Most reasonable people viewing the GNote pentile screen say it is bright, has high contrast, deep blacks and a sharp image.
It is a 24bit Millions of colours screen.
So why the hatred of pentile?
It's got me f#^ked.
Maybe it is due to old arguments that date back years.
There is an old controversy going around between pentile and LCD proponents, which is apples vs oranges because there are pentile lcd's and rgb oled's.
The controversy is, that pentiles use less sub-pixels and therefore should be rated as such in lower pixel density.
This ignores how vision works, which essentially is an illusion.
To disagree is to dismiss basic Buddhism and modern psychology as well as film theory on visual perception.
At the level of pixels, the illusion of vision breaks down for lcd as well as pentile screens.
So while looking at a pentile screen with a magnifying glass can be scary, it is the same for rgb's.
So why did Samsung go back to using the pentile matrix instead of RGB for the Note?
Only guessing, but some of the advantages of pentile are;
Cuts power consumption in half for equivalent brightness, or
Doubles screen brightness for equivalent power
Achieves higher resolution
Provides flexible settings for color control and power savings
Increases cost savings potential and yield for manufacturers
Accelerates adoption of next-generation devices
Makes text easier to read

Contrary to the hype, pentiles allow higher resolution, all the while using much less power. Talk about a no-brainer.
One of the limitations of the pentile is a cross hatched pattern seen on the edge of some images, like a border between red and white, when seen up close(with a magnifying glass). This is so at lower pixel densities but "for higher pixel densities you stand to gain from PenTile" ; is the PenTile matrix bad for you?

Achieve higher resolution - yes, but already given a 1280 x800 resolution, would you prefer it to be pentile or RGB?
No one is complaining about pentile can give higher resolution, its not like we want 800x480 RGB over 1280x800 pentile. But already given the phone is 1280x800, people would rather it be super amoled plus instead of pentile super amoled.
While pentile consumes less power, super amoled screens sucks power like crazy. It is a fact. But that said, i still think the screen is gorgreous. however if you let me choose - RGB over pentile any day.

Well if you are not talking about super amoled, then yes a pentile layout consumes theoretically 33% less power.
If you are strictly comparing pentile RGBG/RGBW to RGB, pentile looks like sh*t i gotta say. At least my atrix did.
Pentile also ages better than sRGB amoled, because the lifespan of the organic amoled subpixels are different from color to color. The pentile ages better because there are simply more subpixels of the color which has the lowest lifespan.

The color which has the lowest lifespan is blue, from what i can recall)
How does RGBG or RGBW have more blue subpixels than RGB? (I am only asking just wanted to know.)

Actually I gotta agree with you on that. My gf had a SGS II and that blue tint bugged the hell outta me. I dont know what they done to it, but i dont think it was a problem with it being RGB.
Pentile suffers from strange color tints on whites.
Hard time rendering shades of gray.
Strange artifacts in low-light conditions.
Ofc all noise is camouflaged by the high resolution.
I would trade for the S-LCD screen of the Rezound any-day,
the only problem with that screen is that it could use abit deeper blacks.

I think this is related to OLED and not Pentile.
The Note screen does seem bluish to me when seen from an angle.
I don't see problems with grey on the Note.
I have view gradients to test the 24bit resolution and if viewed in a 24bit app, 24bit images look fine, otherwise not, but this is not an intrinsic fault of the Note's screen, only of the low res images or apps.
I'm not going to go back through and quote people, but some people said some things that are downright incorrect. Pentile does NOT "increase the resolution." It does exactly the opposite, decreasing it. Pentile has half the red subpixels and half the blue subpixels that RGB does; that means overall, pentile only has 2/3 the pixel elements that an RGB screen has. You can't display more information with fewer pixel elements.
The unpleasant artifacts I notice on pentile screens are small text, lines, graphics, appear fuzzy and sometimes colored on the edges, and when I look at solid colors that use red and blue (i.e.just about everything but solid green) especially white, I get this screen door effect. It's almost like there's a bit of checkerboard pattern to the solid color rather than being uniform. Hold your phone closer to your face and look at a solid white area, especially try to find a solid white area that is next to a solid green area with the brightness turned up all the way and you'll really see what I'm talking about.
Pentile doesn't necessarily use less energy than RGB. There are fewer subpixels, but they're twice as large and put out twice as much light. Energy in = light out. So in theory, the energy should be exactly the same. Perhaps they've found some way to do pentile a little more efficiently on some phones, but it's not an overall rule at all.
Pentile is used because it allows them to make the blues twice as big. Since they had a problem with short life span on those, making them twice as big made them hardier, longer lived, and higher yields in the manufacturing process. That's the ONLY reason for pentile. You could say this allows manufacturers to build higher resolution displays than they otherwise would be capable of (since they're cheating and using larger blues than an RGB would have) but a 1280x800 pentile is NOT "higher resolution" than a 1280x800 RGB! According to definition, they're the exact same resolution, but in reality, the pentile is lower in resolution.
RGB is ALWAYS better than pentile as far as image quality. The reason the Note's screen looks better than the SGSII, even though the SGSII had RGB, is simply because it has a much higher resolution. The benefits from that outweigh the negatives of pentile.
Here's a pic I put together showing the differences, even though you can find the same thing elsewhere on the net:
Thanks for summing that up =) Can we go on now and accept Sammy's gone cheap on us?
I really am not too bothered about what screen the phone uses as long as it looks good, i do think to me it looks fantastic. Lovely and bright and it displays a fantastic picture. If people dont like a particular screen a phone uses then they have the choice not to buy it. Some posts in here are very informative so in that respect thanks. However people that ***** about the phones screen (not necessarily in this thread) have the choice to return it and wait for the screen of their choice to come out.

The general public isn't noticing these artifacts, which makes me think they made the right decision on this one. After all, the General public would definitely notice a higher battery drain. I won't pretend to know the technical details about why Pentile battery usage < RGB.

Probably - but it's not interesting if that's not how you generally use your phone.
I wish I could find the interview, but they interviewed a samsung executive who was quite candid about the whole thing. He said quite clearly that Amoled + is sharper than Pentile. But he said that they went Pentile because in terms of sharpness, Amoled is good enough (i.e. still fantastic) - production is better (i.e. it's cheaper to make) and uses less battery power.
And they are correct. I've watched/read many many reviews of the GNote. For the most part, they all rave about the Screen, complain about the price, and are happy with the battery.
It would have been a mistake to put AMOLED+ in, and have the reviews (still) rave about the Screen, be even more turned off by the price, and only be 'okay' with the battery. (perhaps even complaining about it, saying 'Luckily it has a huge battery, because otherwise you'd be toast)
The GNote is already a niche device - you want to widen its appeal as much as possible.
- Frank
Don't get me wrong, I'm very happy with my Note, including the screen. Search my posts and you'll see me say that several times. I'm a long time pentile hater from the day I first powered on my nexus one and started wondering what was wrong with the screen. Yet I've said several times that the Note's so awesome and the screen otherwise so beautiful that I'm able to overlook the pentile layout.
However I'm not going to read people claiming that pentile is better than RGB without speaking up, because it's not.

(This isn't meant to be a hostile response, I apologise if it comes across that way - it's absolutely not intended)
It doesn't directly, no. But you then go on to point out exactly how it enables much higher pixel densities - in an RGB layout each sub-pixel is the same size, so they need to make the blue sub-pixel at a viable size (as you said,) then make green and red sub-pixels that are the same size again.
On a PenTile screen, they can print the blue sub-pixel at it's required size, but the green component can be much smaller - and as a result, you can fit more pixels into the same space. If you compare the Galaxy Nexus's 316ppi PenTile screen to the S2's 216ppi RGB screen, you'll find that the blue and red sub-pixels are actually of a comparable width.
Sure RGBRGB is technically superior to RGBG in terms of image quality, but after a certain pixel-density:distance ratio, it just doesn't matter anymore, and allows for a greater pixel density regardless of display technology.
As a point of curiosity (I know you gave this first point, I'm just elaborating,) resolution is a measure of the number of horizontal or vertical alternating black and white lines a display can produce while maintaining a certain level of contrast. PenTile screens actually are their advertised resolution. However low-density RGBG will lose some detail in reds, but greens are still fine, and the human eye can't see enough detail in blue to tell a difference there. That's in general though - obviously there are biological differences in people, and that is where the legitimate complaints come from - not from holding a phone 3 inches from your face.
As for whether RGB or PenTile is better - consider that the Galaxy Nexus's 4.65" screen could fit either 1280x720 RG/BG pixels, or 960x540 RGB pixels, and it's too dense to be able to tell the difference in sub-pixel arrangement. I think PenTile actually is better in that case.
small dots and big dots
okay so everyone is forgetting that not so long ago printers used to print using
only one size dot of ink. well the picture from same size dots looked grainy. so the print people came up with different size dots of ink to make the pictures look
amazing. i look at the pentile displays the same way. in comparison the
screens on rgb screens look blocky to me and those on pentile look smoother and
less grainy. iphone just shrank the dots to where the human eye can't detect
them. but i believe to acheive the same thing on a larger screen isn't very
pratical. that's where different size pixels will make images appear smooth.
Some great info that dispels some pentile myths can be found here - http://pentileblog.com/uncategorized/pentile-for-720-hd-oled-smartphones/.
Put simply, a lot of the criticisms of pentile displays are only relevant to particular implementations, and not necessarily to the technology.

I looked at the Note screen under a loupe and I could see a serrated edge along the top of white text on a black bacground. If I looked at it normally I couldn't tell. In this case the pentile doesn't bug me.
What DOES bug me is the low color depth that the Note displays. It is odd as it is inconsistant. If I look at photos it is fine. Some apps though look like the color depth is drastically reduced. Two apps to test are Angry birds Rio, and Google Sky. In AB look at the sky and clouds on the title screen, the shades all blend smooth on other devices (checked on an Infuse). On the Note there is severe color loss and much banding evident. Same with google sky There are these sky gradients, smoother on other OLED screens like the Infuse, much more bandy on the Note. I don't know why on some things like photos the note looks fine, but in many apps color loss and banding is evident. Maybe it is some weird incompatibility of the apps? Maybe they mis-read the screen capability and drop to low color mode? I don't know but it is weird and bothers me much more than the pentile matrix.

Samsung announced its new Galaxy S III smartphone to great fanfare last week, though some observers weren't terribly happy with one particular feature: the 4.8-inch 720p Super AMOLED display uses a PenTile(INFO) subpixel layout instead of the generally more favorable RGB(INFO) layout. At CTIA 2012, we spoke to Samsung about its choice to use PenTile layouts in a large number of its displays, and the answer really comes down to durability and longevity.
Ever since the original Galaxy S in 2010, Samsung has used AMOLED(INFO) (usually branded as Super AMOLED or Super AMOLED Plus) displays in many of its high-end smartphones, and many consumers are big fans of them. AMOLED screens have tremendous contrast, very saturated and vibrant colors, and extremely wide viewing angles. Devices that feature AMOLED displays have a certain 'wow' factor when you first look at them, and many users appreciate that, even if the displays don't provide the most accurate color reproduction. Samsung says that it fully believes AMOLED displays are the best for its mobile devices, and that's why it uses them time and again.
However AMOLED isn't without its faults. Displays that use AMOLED technology have a tendency to deteriorate over time. One doesn't have to look back that far to remember the problems Google had with the original Nexus One smartphone, which featured an AMOLED screen. There were numerous reports of screen deterioration after only a few months of use, and in some cases the display was rendered unusable (HTC, the maker of the Nexus One, eventually switched to using Super LCD displays in later versions of the phone, though it cited supply constraints as the reason for the switch).
Samsung's Philip Berne explained to me that the blue subpixels on AMOLED displays actually degrade the fastest - quicker than the red or green subpixels. With a PenTile layout, the subpixels are arranged RGBG (red, green, blue, green), so they feature more green subpixels and fewer red or blue subpixels than an RGB stripe layout with the same resolution. Because of this, AMOLED displays that have the PenTile layout tend to have a longer lifespan than those with RGB layouts. Since Samsung is selling its phones to users that usually keep them for 18 months or longer, it has to be sure that the display will still offer peak performance at that time. According to the company, PenTile AMOLED displays have proven to be more reliable than those with RGB layouts.
Those that have issues with the PenTile arrangement usually complain that the screen does not look as crisp as an RGB display or that there is odd color fringing along the edges of images, such as app icons. While Berne did agree that the PenTile arrangement's faults are pronounced at lower resolutions, such as qHD or WVGA, high-resolution displays hide the problems due to the sheer density of pixels. The Galaxy S III and the Galaxy Note, for example, both feature high-resolution Super AMOLED displays with PenTile subpixel arrangements (the Galaxy S III has a 1280 x 720 pixel screen, while the Note has a 1280 x 800 pixel display). Under a microscope, one can see the pixel layout on these displays, but in real-world use, it is not visible to the vast majority of users. To that point, the Galaxy S II, which had a lower-resolution WVGA (800 x 480 pixel) display, featured an RGB layout for its subpixels.
Today's choice to use PenTile in its high-end Super AMOLED displays doesn't mean that Samsung isn't working on or won't develop future AMOLED displays that use the RGB pixel layout, provided it can maintain reliability across the board. In fact, the Samsung Galaxy Tab 7.7 tablet features a 7.7-inch Super AMOLED Plus display with 1280 x 800 pixels and an RGB pixel layout, though that screen is obviously larger than what we see on smartphones, thereby making any PenTile-related issues more noticeable.
Is the PenTile subpixel layout something that should be a concern for prospective buyers of the new Galaxy S III? We really don't think so, and in our hands-on time with the device, we really could not see any issues with the screen. Trust me, I tried. Berne did point out that the 4.8-inch display on the Galaxy S III is improved over the 4.65-inch 720p Super AMOLED screen used on the Google Galaxy Nexus, as it features smaller gaps in its subpixel matrix, further minimizing the fringing effects of the PenTile layout.
Some reviewers and users may disagree, and contend that "once you see the PenTile, you can't unsee it," but we really think that the average smartphone buyer (the people that Samsung is actually selling the phone to) will never be the wiser. Additionally, as smartphones get higher and higher density displays, the argument over PenTile and RGB subpixel layouts will become less and less relevant. Are we going to be discussing this matter when smartphones with 1080p displays, perhaps some with PenTile subpixel layouts, come out in the next year or so? We really doubt it.
i wont believe that unless it comes straight from a Samsung press release article
I would say this is a make over from samsung, simply the technology is not ready for mass production hence the pentile.
So before I post this i'd just like to say this is my 1st post, and because of that I was not able to share links to the websites that I wanted to. So if you would like to visit the websites that I point to where I have only quotes with no links, just Google "oled-info note 2 display" and the first website to come up should be where I posted essentially the same thing and you can see the websites I am pointing to. Thanks!
Ok so all of the talk on different articles and forums about the Note 2's display about it not being a pentile, but also not being the SAMOLED+ with the typical RGB stripe got me thinking. Before the pentile discussion began to get heated all over the web, everyone was concerned about their phones' PPI. But obviously once the pentile displays came out and veered away from the typical RGB stripe (maybe there have been other display types b4 the pentile but that’s kind of irrelevant to the point I am going to make) there became a whole ‘nother thing to consider when it came to display clarity. IMHO this clarity comes down to the smallest part that makes up the picture, and that, for all intents and purposes, is the sub-pixel, not the pixel itself.
Now personally when the Note 2 was 1st announced I was pissed that Samsung decided to make the screen bigger and lower the pixel count because I currently have the S3 with Sprint and for me personally, the bigger the screen the better because I use my phone for TV and movies all the time. Now I understood that they wanted to have a 16:9 aspect ratio, but then why not just increase the horizontal, or both, resolution, not decrease the vertical! Especially since it was not a SAMOLED+, but just a regular SAMOLED which obviously meant another pentile right? But then I started reading into the screen and found out that even though it does not follow the typical RGB stripe, it does in fact have all 3 red, green & blue sub-pixels in each pixel instead of sharing pixels like the pentile does, which is shown very clearly in this picture:"".
So this got me curious because as I stated before, at least to my eyes, the sub-pixel count seems to have a greater affect on image quality than just the pixel count itself, which to me was proven when I got my Sprint Galaxy S2 and even though it had the same number of pixels with a .52" larger screen than my original Galaxy S, the screen clarity on my S2 was noticeably better which, if you dont consider the sub-pixel difference, should not be true. So I decided to do a comparison between what I am going to call the "SPPI" (Sub-Pixels Per Inch) of the original Note, the S3, and the Note 2 as I own a S3 and as much as I would love to have a larger screen, I really would not be happy with the huge loss of quality that would normally come when you stretch the same amount of pixels by .7" as the S2 has a 4.8" screen and the Note 2's display is 5.5", and what I found out really surprised me.
So here's the math of how I got to my conclusions. 1st of all according to the information from Samsung that can be found here: "" the sub-pixel count on the SAMOLED WVGA screen is 768,000 and for the SAMOLED+ WVGA screen it is 1,152,000. Now a WVGA screen is 800x480, which comes to 384,000 total pixels, the Note 1 is 1280x800 which = 1,024,000 and the S3 and Note 2 both are 1280x720 equaling 921,600. Now at this point I needed to figure out the number of sub-pixels on each phone by doing a simple algebraic comparison of the number of pixels to sub-pixels between the WVGA screen and each one of the other phones, which is done here:
Note 1: 384,000/768,000=1,024,000/x and x = 2,048,000 sub-pixels
Galaxy S3: 384,000/768,000=921,600/x and x = 1,843,200 sub-pixels
Note 2: 384,000/1,152,000=921,600/x and x= 2,764,800 sub-pixels
Now at his point I needed to take the aspect ratio of each phone, which is 16:10 for the 1st Note and 16:9 for the other 2 phones, and use the formula on this website to get the horizontal and vertical “sub-pixel resolution”: "". In doing this I came up with the following resolutions:
Note 1: 1,810 x 1,131
Galaxy S3: 1,810 x 1,018
Note 2: 2,217 x 1,247
I then put that information in with the screen sizes in this website: "" and came up with the following “SPPI” results:
Note 1: 402.7 “SPPI”
Galaxy S3: 432.6 “SPPI”
Note 2: 462.5 “SPPI”
So in a similar scenario as the Galaxy S vs. S2 screen clarity comparison, as long as my calculations are correct, theoretically not only should the Note 2 have a better clarity than the original one despite having a larger screen and lower resolution, it should also be clearer than the Galaxy S3! I have to say I was shocked at that and very much look forward to actually holding one in my hand to compare against my S3. I’d like to hear some opinions as to whether in general people agree or disagree with what I came up with here and for anyone that has held the S3 and Note 2 side by side if these calculations hold up in the real world.
Thanks!

**Quick edit: as someone on a different site pointed out to me, the screen size on the Note 2 is actually 5.55", not 5.5". So according to the members.ping.de dpi/ppi calculator that I used for this calculation, the "SPPI" for that device would actually be 458.3. Not that it really makes any difference, but if I'm gonna do all this work I might as well do it right
In the words of Mythbusters.... "myth, plausible" lol
Swyped from my finger to your face, on my Samsung Galaxy Note.
What you say it's completely true... What you call sub pixel its just a diode led... So adding more leds per pixel gives you better quality.. Indeed the pixels are Rgb and not pentile as someone will try to say here... Does not matters how are they arranged a red/green/blue pixel its an Rgb pixel... That said your math are to complicated and it's easier..
It's 1280x720 =921600 pixels note 2
For Rgb its 921600x3= 2764800 sub pixels or leds but distributed in 921600 leds of each color
It's 1280x800 = 1024000 pixels note 1
For pentile its 1024000x2=2048000 sub pixels or leds because it's 2 leds per pixel distributed in 2048000x¼ red + 2048000x¼ blue + 2048000x ½green
So clearly Rgb arrangement has way more leds than pentile arrangements and finally as easy as
2764800÷5.55=498162 leds per inch in the Rgb arrangement and
2048000÷5.3=386415 leds per inch in the pentile arrangement
So that's why note 2 screen its way better than note 1 screen

Because the S3 and Nexus are both pentile displays with a 1280x720 res, they both have 1,843,200 sub-pixels and if u put that into the same ppi calculator as I used b4, inputting the same horizontal and vertical resolutions and just changing the screen size to 4.65", it comes out to 446.6 "SPPI" which is still less than the note 2
c'est bien ça.

The original Galaxy S has a total of 768,000 sub-pixels and an aspect ratio of 5:3, making the number of horizontal & vertical sub-pixels 1,131x679 on a 4" screen which once again according to members.ping.de ppi/dpi calculator the "SPPI" would be 329.8. So the difference between that and the Note 2 should be pretty significant!

But then I started reading into the screen and found out that even though it does not follow the typical RGB stripe, it does in fact have all 3 red, green & blue sub-pixels in each pixel instead of sharing pixels like the pentile does, which is shown very clearly in this picture:"".
So this got me curious because as I stated before, at least to my eyes, the sub-pixel count seems to have a greater affect on image quality than just the pixel count itself, which to me was proven when I got my Sprint Galaxy S2 and even though it had the same number of pixels with a .52" larger screen than my original Galaxy S, the screen clarity on my S2 was noticeably better which, if you dont consider the sub-pixel difference, should not be true. So I decided to do a comparison between what I am going to call the "SPPI" (Sub-Pixels Per Inch) of the original Note, the S3, and the Note 2 as I own a S3 and as much as I would love to have a larger screen, I really would not be happy with the huge loss of quality that would normally come when you stretch the same amount of pixels by .7" as the S2 has a 4.8" screen and the Note 2's display is 5.5", and what I found out really surprised me.
So here's the math of how I got to my conclusions. 1st of all according to the information from Samsung that can be found here: "" the sub-pixel count on the SAMOLED WVGA screen is 768,000 and for the SAMOLED+ WVGA screen it is 1,152,000. Now a WVGA screen is 800x480, which comes to 384,000 total pixels, the Note 1 is 1280x800 which = 1,024,000 and the S3 and Note 2 both are 1280x720 equaling 921,600. Now at this point I needed to figure out the number of sub-pixels on each phone by doing a simple algebraic comparison of the number of pixels to sub-pixels between the WVGA screen and each one of the other phones, which is done here:
Note 1: 384,000/768,000=1,024,000/x and x = 2,048,000 sub-pixels
Galaxy S3: 384,000/768,000=921,600/x and x = 1,843,200 sub-pixels
Note 2: 384,000/1,152,000=921,600/x and x= 2,764,800 sub-pixels
Now at his point I needed to take the aspect ratio of each phone, which is 16:10 for the 1st Note and 16:9 for the other 2 phones, and use the formula on this website to get the horizontal and vertical “sub-pixel resolution”: "". In doing this I came up with the following resolutions:
Note 1: 1,810 x 1,131
Galaxy S3: 1,810 x 1,018
Note 2: 2,217 x 1,247
I then put that information in with the screen sizes in this website: "" and came up with the following “SPPI” results:
Note 1: 402.7 “SPPI”
Galaxy S3: 432.6 “SPPI”
Note 2: 462.5 “SPPI”
So in a similar scenario as the Galaxy S vs. S2 screen clarity comparison, as long as my calculations are correct, theoretically not only should the Note 2 have a better clarity than the original one despite having a larger screen and lower resolution, it should also be clearer than the Galaxy S3! I have to say I was shocked at that and very much look forward to actually holding one in my hand to compare against my S3. I’d like to hear some opinions as to whether in general people agree or disagree with what I came up with here and for anyone that has held the S3 and Note 2 side by side if these calculations hold up in the real world.
Thanks!
-Brian
**Quick edit: as someone on a different site pointed out to me, the screen size on the Note 2 is actually 5.55", not 5.5". So according to the members.ping.de dpi/ppi calculator that I used for this calculation, the "SPPI" for that device would actually be 458.3. Not that it really makes any difference, but if I'm gonna do all this work I might as well do it right

right, pentile is not limited to RGBG
BUT: as the pics from verve showed it looks like we get a real RGB matrix (not the regular stripe, but still RGB)!
for us this means that the note 2 will have 50% (2x1,5=3) more subpixels (actually lesser because of the lesser resolution, see calc afterwards), and due to this fact it's almost sure that the "disadvantage" (in terms of DPI) of having a slightly bigger screen will be overcompensated by this fact!
some maths:
note 1: 1.280x800x2 = 2.048.000 subpixels
note 2: 1280x720x3= 2.764.800 subpixels
in total this is an increase of exactly 35% in terms of subpixels!
additionally the manufacturing quality of OLED screens from samsung increased during the last year, so i guess that at least the screen will be a real improvement! and i tend to say that 2gb ram will also make a feel-able difference!
don't get me wrong, i'm also a little bit disappointed about the specs,
but over all they are worth upgrading, at least from my point of view!

My apologies, I would have given you credit for finding out the total number of sub-pixels for those 2 phones in my post if I had seen it. It would have eliminated the need for me to have to figure it out to get to my conclusion. But I was more looking to find how many sub-pixels per inch there were more so than just how many total because I feel like having that allows for a good mental idea of how the screen clarity will compare to peoples' current phones. For example I have the S3 right now so I wanted to do this comparison so I could have some idea of whether or not the clarity will be comparable to that phone since it has a .75" smaller screen with the same resolution. Come to find out that theoretically it should be better and. Thats more why I created this post.. Once again though I apologize for not giving you credit where deserved

Well before I give you the figure I have to say first that all the screens I have been comparing so far have been Super AMOLED screens. And organic LED screens are VERY different than regular IPS LCD screens. I actually owned a HTC ONE X for a little while because I didn't want to have another pentile display because I was worried that the S3 would look kind of grainy like the original Galaxy S. So I upgraded from the S2 to the One X and within 2 days I couldn't take it and returned it for an S3(which ended up looking amazing). But when I had the HTC I even missed the 800x480 display on my S2, and that's because even though the One X has a VERY clear screen as far as not having any pixelation, the LED screens on the Samsung, IMHO, blow away the LCDs on One X. The blacks are actually totally black, not just dark gray lol, the colors are sooo much brighter and saturated because the contrast ratio is technically infinite as compared to I believe 1400:1 on the One X. So compared to the S3 the colors just look washed out. Now there are some people out there who don't like the colors being so intense, but I believe that it just makes everything you watch on your phone just so much more enjoyable. And as I said not everyone agrees but if you never used an S3, go to the store and put your phone side by side and you will notice a TINY bit more pixelation (I mean your nose basically has to be touching the phone lol) but MUCH brighter colors and MUCH deeper blacks. And because of the difference of how the LED screens display as compared to the LCDs just the numbers really aren't going to tell the whole story. So I would STRONGLY recommend not letting the numbers deter you from at least checking the Note 2 out in person. (If you couldn't tell by now I'm a strong advocate of Samsung's LED screens lol, but for good reason) So after that long-winded speech the simple answer is the One X has a "SPPI" of 541.2 lol

hell ya, i just wan the new Note 2...
but will it be Kernel Brick-free?... zzzz.....
btw the screen should be awesome... long live Super Amoled
Very interesting information.
Just want to get my hands on the Note 2!
I was only disappointed by the screen resolution But this thread changed my mind, might switch to note 2 from S2, I still think the screen is big but the S-Pen and it's features are too much attractive :silly:

another thing:
i'm with you that amoled is superb to lcd,
but few things about their disadvantages:
possible burn-ins
much more energy consumption as most people think
almost all displays have some tint (mostly yellowish or blueish), due to
big production (quality) differences between screens (had to cherry-pick my perfect one out of over ten (!) devices), there are a lot of threads about this. in short: screens from the middle of the 'wafer' are best, the more from the off-center your screen got cut out the more tint and uneveness you would have). this is due to the 'old' lithography process used, the new one (hope they used it with note 2 screens) with fine metal masks and perhaps lasers should improve this dramatically!
litte oversaturated, almost ever a not so good low grey level seperation (and often a bad gamma or mdnie factory calibration as well), search for gamma.png and or 'black crush' where low greys got cut-off
about contrast:
technically impossible to be oo!
black is NOT 100% black, as every (!) active oled screen emits a very small amount of light when active! also lots of threads regarding that, try it out: go into a totaly dark environment, display a black image and,VERY IMPORTANT, let your eyes accomodate for 1min! then look at the screen also with this method you will notice the uneveness and lithography projected dirt (dust) particles as with a microscope!
don't get me wrong, i love my amoled screen and i do not want to sound like a teacher!
but one has to be aware about this things as well...

The Note 12.2 uses a pentile [RB][GW] subpixel layout vs the TabPro 8.4 which has full [RGB].
Pentile screens use just 2/3 of the subpixels compared to full RGB.
Accordingly subPixel counts:
Note 12.2 ... 2560x1600x2 gives about 8 million sub pixels
tabPro 8.4 ... 2560x1600x3 gives about 12 million
Disappointing for a device priced so high with a 'Pro' tag?

Turn that in to PPI and it doesn't look so bad. The gross PPI for the N12.2 is 247. The addition of the white sub-pixel (25% of the total count) reduces the RGB pixels by 8% each leaving them at 227 PPI each. The iPad Air is at 264 PPI and the net RGB for the N10.1-14 is 274 (gross is 299) resulting in the N12.2 having 14% fewer RGB pixels per inch than the iPad and 17% less than the N10.1-14. It's 24% less than the N10 which uses a RGB stripe display. Whether those PPI reductions are comparatively noticeable depends more on individual visual acuity and the distance the device is viewed from than anything else. Some reviewers commented on the display being less sharp when compared to the Tab|Pro 8.4/10.1 and N10.1-14.
Same here. No perceived difference in sharpness/quality with my Nexus 10.

All these calculations are a waste of time and effort. I can't tell the difference side by side so no one is going to be able to honestly perceive that one is better then another... These kind of arguments and numbers are only for haters or people who can't afford a device but want to convince themselves they really don't want it because of some technical specs that can't be perceived in real world usage/conditions.
Look it is what it is.
Samsung used a pentile screen in the 12.2 . Pentile screens have 2/3 of the sub pixels of a normal RGB display.
The display quality of the TabPro 8.4 is incredible, 1078 sub pixels per inch,
whereas the 12.2 pentile display clocks in at 494 sub pixels per inch.
As others have noted, the 12.2 Note screen is more than usable, but it's inferior to a full RGB display.

As I said actual experience matter than paper specs and calculations etc. I have seen no one disappointed about the screen not on here or in a YouTube video but you . everyone is charmed by the beauty of the screen and happy with it . those calculations are not a deal breaker for anyone around here and if you are not happy with what you would get with the note pro you could simply get the 8.4 tap pro its a personal reference .

Sorry but you are being stupid. Stop analyzing the specs and actually try out the devices. No way you can perceive any difference under normal operating conditions. I truly feel sorry for you...
It's an lower quality display. The difference can be seen, and stated and is unexpected in a premium product.
If your charmed by the product or unable to see the difference, all the better.

Actually the way pentile and rgb stripe displays render information is totally different. Rgb use an entire pixel (rgb) to create an image. Rgbw displays render on the subpixel level. The pixels actually have no locked in grid they must conform to but rather work with all those around them to render the same resolution image as rgb with 2/3 of the subpixels. There is no discernable difference except that rgbw actually conforms to the process of the human eye better and thus can achieve better color parity with real life.
PenTile® technology is biomimetic, meaning it is designed to compliment the complex mechanics of the eye-brain system. As a simple example of eye mechanics consider how the eye utilizes the color blue. The eye has cone receptors that sense color and brightness, and discern patterns. These cones are sensitive to different wavelengths of color—primarily red, green, and blue. The blue cones detect mostly color (chroma) information, while the red and green cones do most of the work resolving images by discerning luminance, edges, and structural details of images, as well as contributing to color vision. The red and green cones are used independently, each cone seeing a "dot" of black and white—ignoring its color to produce high resolution luminance perception—and are used in opposition, comparing the amount of red versus green, to produce low resolution color perception.
If there was an obvious disadvantage I doubt one of the largest and most successful electronics companies to ever exist would not use pentile. Or have you all forgotten that the NOTE 3 pentile is hailed as the best screen on a phone period (with regards to new 2k screens coming this year) even beating out all lcd rgb competition?

PREACH.
The only other image related difference, I believe, is that the tab can record HD video at a higher fps. The camera only weighs in at a craptastic 8 MP, and I don't use my tablet, of all things, to film video. The s-pen, on the other hand, is fantastic for graphic work.

How is this stupid? We are not talking about a $100 or a $200 device; this is the most expensive Android tablet where EVERYTHING should be premium. When the build quality is already meh, not having 2560x1600 at standard RGB stripe for a LCD is a kick to the teeth.
The comparison with the Note 3 is asinine, because this is not 1080p AMOLED on a 5.7" screen where the tradeoffs with Pentile are more than worth it. 2560x1600 RGB is only 227 ppi, Pentile reduces it to 2/3 to 150 ppi. The claim you make that people can't see the difference like Retina iPad is ridiculous.
My brother has the 12.2 which I have actually used it so don't use the "you didn't tried it out hurr hurr" excuse to shut people up. Straight edges are clearly blurrier than my iPad Air. But hey if you like Samsung to continue selling you inferior specs at high prices be their guest.
But at the end it's not the pixel density. If you get the same effect with new technique, you don't need so high density. But as you said you see the difference in straight edges so probably buyers should then first check the screen do they see the same or not.

I have the note 3, note 10.1 2012 and the note pro 12.2, the note pro is much better than my note 3 and my note 10.1 2012 combined. If you want to complain about ppi, then you should complain about the first note 10.1. 1280 x 800 on a 10.1 inch screen vs 2560 x 1600 on a 12 inch screen. Considering the first note 10.1, that is a screen upgrade to me.

Good, I hope you don't buy a 12.2 for this reason. No one really cares and it's your loss... I firmly stick by my claims, I have better then 20/20 vision and at normal viewing distance (i.e. 18inches or so) it's impossible to tell the difference. You go ahead and stick face right up to the tablet screens and compare them side by side finding that under non normal usage it's technically possible to see a slight difference if that is what you need to do. 99.9% of people who want this tablet have no issue with the screen cause if you take away the specs and evaluate the screen under normal usage conditions it's as good as anything on the market. If you think your little online rant about the resolution is going to force Samsung to make a screen that meets your specs you need a reality check. I'm going to enjoy my Note 12.2 and in a year from now Samsung will likely release a newer upgrade model with a "better" screen (as that is what happens every year) that may meet your technical requirements. Until then you enjoy your little iPad Air and I'll me enjoying my Note 12.2!
How is this thread still going? Either you buy one, or you don't. I bought it, and I'm never looking back. It has all the functionality I need, plus things I've not yet gotten around to messing with. It's an awesome tablet. If subpixels are what you're in the market for, then you have done your homework and know this isn't what you need.
This is what I need. Very pleased.
Thank you, and goodnight.

Samsung FIRMLY believes that pentile is a better screen technology than lcd they are the ones driving it's development. It is more akin to how the human eye actually works and it is easier on the eyes. The number of sub pixels is the same just one per every four is white, It is 30% more energy efficient and it requires fewer sub pixels to display at the same resolution, the human eye will see it the same as a higher resolution. To be technical though gentile displays have ZERO sub pixels. Each individual subpixel is rendered separately. They are not in pre defined groups and can be combined into any number of logical pixels. So technically the screen is using 12,288,000 individual pixels.*
conventional RGB stripe displays render (draw) images by assigning a color and luminance (brightness) to an entire RGB-triplet as a whole pixel, adjusting its three RGB subpixels to set a single addressable point. Images on a PenTile RGBW™ panel are subpixel rendered, meaning they are drawn at the subpixel level (the individual points of light), rather than to the whole pixels of an RGB stripe display. In fact "pixels" in the traditional sense have been eliminated in PenTile RGBW™ displays; individual subpixels are not restricted to use in one pixel group, but instead participate in multiple "logical" pixels in their surrounding vicinity.
Subpixel rendering dramatically increases addressability and enables the sophisticated image processing used in PenTile RGBW™ displays.
That is from nouyance the company that invented pentile and rgbw They also say
PenTile® technology is biomimetic, meaning it is designed to compliment the complex mechanics of the eye-brain system. As a simple example of eye mechanics consider how the eye utilizes the color blue. The eye has cone receptors that sense color and brightness, and discern patterns. These cones are sensitive to different wavelengths of color—primarily red, green, and blue. The blue cones detect mostly color (chroma) information, while the red and green cones do most of the work resolving images by discerning luminance, edges, and structural details of images, as well as contributing to color vision. The red and green cones are used independently, each cone seeing a "dot" of black and white—ignoring its color to produce high resolution luminance perception—and are used in opposition, comparing the amount of red versus green, to produce low resolution color perception.
The PenTile RGBW™ layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the red and green cones, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone types. Combined, this optimizes the match of display technology to the biological mechanisms of human vision.
Other human-vision factors such as the logarithmic representation of luminance values, variable resolution between the center and edge of vision, and the separation and compression of brightness and color differences are also exploited in the design of PenTile RGBW™ displays.
The human eye perceives the resolution of the PenTile RGBW™ panel as the same as an equivalent RGB stripe panel, yet the PenTile®*panel uses one-third fewer subpixels. Consider the figure below to understand how this is accomplished.
At the top is the PenTile RGBW™ layout; at the bottom RGB stripe. The circle at the bottom center demonstrates the finest pattern of vertical black and white lines an RGB stripe display is capable of rendering. This requires three columns (R + G + B) be turned "on" and an equivalent width of three columns be turned "off" to write one cycle of a black and white line. From a suitable distance this collection of color subpixels appears to the eye as a white line.
The top center circle shows the equivalent pattern of vertical black and white lines written to the PenTile RGBW™ layout. From a distance the array of color subpixels in two columns will appear to the eye as a white line, identical to that generated by the RGB stripe layout, and the following two columns will write the corresponding black line. With only four columns being used to accomplish the same linear cycle that required six columns for legacy RGB stripe, two columns are saved. Hence, PenTile RGBW™ technology maintains the same resolution with one-third fewer columns, one-third fewer subpixels and one-third fewer transistors in the array. This results in wider columns and improved aperture ratio (ratio of transmissive area of a subpixel to the total area of that subpixel).
The circles on the right of the figure demonstrate the finest pattern of black and white lines which may be written horizontally to RGB stripe (bottom) and PenTile RGBW™ (top). Note that both layouts require the same number of rows for horizontal lines.
from this information we can see that a rgb display and a rgbw pentile are equal in displayed resolution and the pentile is more efficient. In black and white images and full color media Petite and rgb are 100% indistinguishable and only when displaying text against a fully saturated background (color text against a solid Colored background) or a sudden transition between two colors can a difference be seen and these are almost unnoticeable on high density displays like the Note 2014 or Note 12.2 pro. What you call drawbacks to pentile I call progress and efficiency. If I can't see a difference there isn't one. Only mine is bigger and more useful with better battery life. I owned the 2014 and work around and begrudgingly sell ipad airs on regular basis. I also have perfect vision in one eye and nobody I have EVER had come into my store has seen the 12.2's Screen as anything short of magnificent. Yes I suppose if you get close enough to your screen that you can barely focus on it that You could see a difference but ya Know I have a life and at normal viewing distances it is flawless. I mean I guess I better not buy a laptop anytime Soon since their dpi's are lower than an ipads right? Or if I want something really worth owning I need that 20" 4K tablet. And my TV is only 1080p? Its 50" THAT'S ONLY 44 DPI OMG I BETTER TRASH IT!!! Forget viewing distances I can't believe I enjoy this crap. I need at least an 8K tv to get a good dpi now I just need to wait about 6 years before I can own a tv again. And a 100" tv? Give me 16k and we can talk.

How is this thread still going? Either you buy one, or you don't. I bought it, and I'm never looking back. It has all the functionality I need, plus things I've not yet gotten around to messing with. It's an awesome tablet. If subpixels are what you're in the market for, then you have done your homework and know this isn't what you need.
This is what I need. Very pleased.
Thank you, and goodnight.

you said what i wanted to say exactly last night but i decided not too since things are getting awkward and pointless since he clearly is decided not to buy it but also the thread seems to be to make people stop buying the device based on some quality calculations
Maybe Google has taken cuts with the phone?
I hear the moto x 2014 compared to galaxy S5, the screen difference is pretty big.
One uses amoled and one uses super amoled. Hopefully the 2k resolution will help the brightness and vibrancy.
What do you guys think? I haven't held a moto x and S5 together but I absolutely love the S5 screen.

It's harder to push light through more pixels, so sure you can get a stronger backlight, but then you get more power consumption and heat.

Huh? You don't push light through pixels with amoled screens. Per pixel brightness is certainly not affected by resolution, perhaps only with LCD screens.

Amoled displays don't have backlights, the display itself is the source of light.

My mistake, completely forgot that part about AMOLED. Been using IPS screens since I had a Galaxy Nexus, and that screen was junk.. so I've been wanting to stick to IPS. My G3 is gorgeous, so I'm kinda scared to see the N6 with AMOLED.

AMOLED is the screen technology. "Super AMOLED" is just Samsung's brand name for their own screens using AMOLED technology, not a separate technology. It remains to be seen what the Nexus 6 screen looks like when compared to Note 4.
Are you sure cause the S2 with Super AMOLED was significantly better than their regular AMOLED models like the GNEX.
HTC One M8
I've not used AMOLED since my Galaxy Nexus, but it was horrendous. Banding visible all over the screen on grey or beige (light colored) screens.
Plus, it had burn in on the status bar that I could always see on full screen youtube videos etc. Was terrible.
I'm wondering have they improved the hardware technology since then or can I expect that again on the Nexus 6,
Look forward to the reviews on here after launch. :laugh:
The OCD fanboys who buy the first wave will be busy detailing the issues. I used to be one of them. I'll wait till the second wave this time. haha :good::laugh:

Super AMOLED is based on AMOLED a technology, but has an integrated digitizer instead of it laid on top, making it brighter and more vibrant. It also reflects less sunlight than a standard AMOLED screen.
It is their marketing term, but does have some modifications

Imagine if they used non pentile
This is a quick pull from wiki explaining the difference between all amoled screens
Super AMOLED[edit]
Super AMOLED is Samsung's term for an AMOLED display with an integrated digitizer, meaning that the layer that detects touch is integrated into the screen, rather than overlaid on top of it. According to Samsung, Super AMOLED reflects one-fifth as much sunlight compared to the first generation AMOLED.[21][22] The display technology itself is not changed. Super AMOLED is part of the Pentile matrix family. It is sometimes abbreviated SAMOLED.
For the Samsung Galaxy S III, which reverted to Super AMOLED instead of the pixelation-free conventional RGB (non-PenTile) Super AMOLED Plus of its predecessor Samsung Galaxy S II, the S III's larger screen size encourages users to hold the phone further from their face to obscure the PenTile effect.[23]
Super AMOLED Advanced[edit]
Ambox current red.svg
This section is outdated. Please update this article to reflect recent events or newly available information. (January 2014)
Super AMOLED Advanced is a term marketed by Motorola to describe a brighter display than Super AMOLED screens, but also a higher resolution – qHD or 960 × 540 for Super AMOLED Advanced compared to WVGA or 800 × 480 for Super AMOLED. It also is 25% more energy efficient. Super AMOLED Advanced features PenTile, which sharpens subpixels in between pixels to make a higher resolution display, but by doing this, some picture quality is lost.[24] This display equips the Motorola Droid RAZR.[25]
Super AMOLED Plus[edit]
The Samsung Galaxy S II, with a Super AMOLED Plus screen
Super AMOLED Plus, first introduced with the Samsung Galaxy S II and Samsung Droid Charge smartphones, is a branding from Samsung where the PenTile RGBG pixel matrix (2 subpixels) used in Super AMOLED displays has been replaced with a traditional RGB RGB (3 subpixels) arrangement typically used in LCD displays. This variant of AMOLED is brighter and therefore more energy efficient than Super AMOLED displays[26] and produces a sharper, less grainy image because of the increased number of subpixels. In comparison to AMOLED and Super AMOLED displays, the Super AMOLED Plus displays are even more energy efficient and brighter. However, Samsung cited screen life and costs by not using Plus on the Galaxy S II's successor, the Samsung Galaxy S III.[18]
HD Super AMOLED[edit]
Galaxy Note II subpixels representation, based on 400X image of the Note II display[27]
The Galaxy Nexus, with an HD Super AMOLED screen[28]
HD Super AMOLED is a branding from Samsung for an HD-resolution (>1280×720) Super AMOLED display. The first device to use it was the Samsung Galaxy Note. The Galaxy Nexus and the Galaxy S III both implement the HD Super AMOLED with a PenTile RGBG-matrix (2 subpixels/pixel), while the Galaxy Note II uses an RBG matrix (3 subpixels/pixel) but not in the standard 3 stripe arrangement.[27]
HD Super AMOLED Plus[edit]
A variant of the Samsung Galaxy S3 using Tizen OS 1 was benchmarked using a non-pentile HD Super AMOLED Plus screen in 2012.[29]
Full HD Super AMOLED[edit]
As featured on the Samsung Galaxy S4[30] and Samsung Galaxy Note 3. It has the broadest color gamut of any mobile display of up to 97% of the Adobe RGB color space, hence making it a wide-gamut display.[31][32]
Future[edit]
Future displays exhibited from 2011 to 2013 by Samsung have shown flexible, 3D, unbreakable, transparent Super AMOLED Plus displays using very high resolutions and in varying sizes for phones. These unreleased prototypes use a polymer as a substrate removing the need for glass cover, a metal backing, and touch matrix, combining them into one integrated layer.[33]
So far, Samsung plans on branding the newer displays as Youm.[34]

OMFG are people here really this clueless? Samsung calls ALL their AMOLED panels Super AMOLED. That includes the ones they sell to Motorola and Nokia. They are ALL made by Samsung. The reason why the Moto X 2014 doesn't look as good as the Galaxy S5 is because Samsung ALWAYS sells the last generation to their competitors and saves the latest generation for themselves. In other words what you see on the Moto X is the same tech as the Galaxy S4, not the S5. And for those dumb people who keep on saying higher resolution means lower brightness, this is only true for LCD since they use a backlight and it has to shine through each pixel, with more pixels decreasing the brightness overall. AMOLED is completely different in that each pixel is its own light source and when you pack them together, they will be brighter not dimmer, just like how your vanity mirror in your restroom will be brighter with three small 600 lumen bulbs near each other versus just one 900 lumen bulb.

Ah yes, now I remember those black spots too.. what exactly caused those and can we expect this on the N6?
Hopefully screen burn is a thing of the past, especially with the nav and status bars going transparent on the home screen.
If the display is PenTile, that will probably kill it for me right away. I can't stand the fuzziness that comes with that junky setup. I bought a Yoga 2 Pro and noticed it right away which is part of why I returned it. I also hate how AMOLED has a very blue/green hue to it.. guess we'll see how the N6 turns out.

For me both suck... cause of degradation of the organic led.. colors become toned... and burn in issue.. they are simply inadequate.. expecially at that price...
From what I recall Samsung makes all AMOLED displays so you should expect it to be great. Google wouldn't put a bad display on a flagship phone.

screen burn isn't a thing of the past.. beacause the technology il still the same.. organic led degradate with use.. losing brightness and uncalibrating all screen colors (this with homogeneous wear) but some elements like status bar icons and navbar buttons are always in the same position!! And they will burn in inevitably

Super AMOLED is a version of AMOLED display technology that integrates a capacitive touchscreen layer directly into the display instead of overlaying it on top of the display, as has traditionally been done. This results in a thinner design that uses less power and reflects less light, and as a result works better outdoors.
