Till now, I was under the impression that Sharp was the only supplier of the display on the Mix. But thanks to @wu5262, I've learnt that that Xiaomi has also used AU Optronics as a supplier for the display.
From the images, it looks as if the AUO screen has a cooler color temperature compared to the Sharp panel which looks warmer next to the AUO display. While I don't notice a big difference in colors or contrast from the images, I would have preferred to have that AUO display solely because I prefer displays which have a cool color temperature.
At least, the screen on my mix doesn't look warmer than the displays on my other devices. So it doesn't bother me that much. As I haven't seen a device with an AUO display, I can only comment on the Sharp panel. Even though it looks warmer in the photos below, it looks uniform and does not exhibit issues common with TFT panels like backlight bleeding or IPS glow. If you look at reviews of the LG V20 or HTC 10, both using IPS panels, you'll see that both the devices exhibit some amount of backlight bleeding.
So, as far as quality between the Sharp and AUO panel is concerned, I wouldn't say that one appears to be of a higher quality than the other. Though, this is one of those rare times when I've seen Sharp appear warmer than an AUO panel.
If anyone owned the Mi Pad, the AUO display was too yellow compared to the decent Sharp panel. At least thats not the case here.
I guess preference for warmer vs. cooler display varies from user to user. I prefer displays on the cooler side while some may hate the blueish tint and want a warmer display.
Which display panel does your Mix have? Would you have preferred one over the other? Comment below!
You can check this by using AIDA64 or going to Settings» About and tapping on kernel version a few times until the CIT interface loads.
In CIT, select Version info and scroll down to LCM Info.
You will see either Sharp fte716 or AUO fte716
Both displays are good. So there isnt anything to worry when you're buying. This thread isn't meant to show that one is better than the other. Its just to show that the AUO is factory calibrated to have a cooler (blueish) color temperature whereas the Sharp is slightly warmer compared to the AUO.
Please see the difference for yourself. Source : Link (Credits to @wu5262)
The Sharp fte716 is on the left and the AUO fte716 is the one on the right.

As you can see, even while using the calibration settings, the AUO still appears cooler than the Sharp panel.
Side by side comparison with my Galaxy Note 4. As you can see, the display on the Mix has excellent contrast and colors for an IPS panel and you don't have to worry too much if you're coming from a QHD or AMOLED panel
AMOLED vs IPS! But I feel the Sharp display on my Mix compares well with the QHD AMOLED on my Note 4. What do you think?
The Sharp display doesn't look any warmer than the displays on my other devices like my XPS 15 or my tablets and monitors. The AUO may have a blueish tint which is why it appears cooler in the images.
This leads me to believe that Sharp has a better calibrated display as I don't feel that the display is yellowish in real usage scenarios.
While I can live with the Sharp panel, I would be devastated if I happen to see a Mi Mix using Sony or ISOCELL camera sensors!
Still like the sharp one, the Display looks way better then my oneplus 3T or even my s7e.. ^^

Better than one plus 3T sure, it's very possible.
But I find it hard to believe it's better than s7e. I don't own a s7e myself. but my wife does, and it's quite easy to notice the difference. Both colour, resolution and technology used in s7e are superior than Mix. I did owned s6plus edge before and that screen looks better than mix.
FYI, my panel is Sharp also.
But liked i said many times before, I now forget the screen difference after using the mix for a while xD. As long as I don't put 2 screen next to each other to compare, this doesn't bother me at all.

Yeah! The S7 Edge has one of the best displays in the market! Kinda makes me miss AMOLED so I don't want to think about it too much! I even paid about 20-30% more than the S7 Edge to get this device and now I happen to know that there is another panel. I guess, once you go AMOLED, there's no going back eh?
PS, if you ever happen to know there is another Camera sensor supplier (Sony), don't tell me!

LOL on the camera,nothing surprises me w/any mfgs anymore.
I believe HTC has done similar w/displays on some models on their flagship HTC One devices in years past.
As for my MIX,according to the app AIDA 64,mine has the Sharp brand display.
I still have a Samsung Galaxy Note 4 for side by side comparison,& outside of the differences in the black tones
(& really not that much different IMHO),I'm quite impressed w/the overall quality of this display.
TBH,until I did a double-take & reverified that this was an LCD Display,if asked which it was,I woulda said it's an OLED/AMOLED Display...........................

Yeah, you're correct. The HTC 10 used panels from Sharp and Tianma. Surprisingly, the Tianma was voted the slightly better looking panel by most people.
While I am aware that most devices that use LCD displays source panels from multiple suppliers, I didn't expect the Mix to have multiple suppliers due to the device having a custom rounded display and the device being produced in limited quantities.
But it looks like the majority have Sharp panels. The AUO may have been on pre-production units.

Maybe Sharp is the major supplier while AUO is the backup producing a smaller quantity of panels.

If you can point me to the exact link of that image, I will try to remove it. I guess when you quote my post to reply, you can see the links to all the images. Kindly post the exact link so that I can remove it.
I would have done this myself but I cant figure out which one it is as I dont get any images of the nail.
EDIT: I think this is some bug with the XDA app as I don't see any images of nails on any of my devices, even on the XDA app. I have also checked the links to all the images uploaded and still no nails! But if you can help me with the reason why the image is showing up, it would be very helpful.

I say warmer compared to the AUO display because it looks neutral\natural to me when compared to the devices I have. This leads me to believe that the Sharp display is better calibrated.
Though some may prefer the cooler AUO more pleasing.

Personally, I prefer the cooler calibrated display, which is why I asked. I'd probably compare it against my Nexus 6P to see if I could tolerate it, which ever display the one I get to see in person has.

I don't know about the technical way... but there is a simple way... load a black backround.. and if it's not totaly black and you see a washed out black then you have a SLCD, if it's totaly black then it's a AMOLED.
You could probably see in settings or something.

Because this is not the only difference.
Amoleds use that pentile pixel pattern, have noticeable gaps between pixels, drain huge amount of power on black text on white background, grossly over-saturate and poorly manage colors, burn in.
So it comes down to your personal preferences. There are a lot of people who are seriously irritated by pentile "drizzle" around small text or that grainy pixellated look due to the big gaps between pixels but don't give a damn about those huge viewing angles or deep blacks which you will distinctly notice only in the night anyway.
So I am also seriously thinking about trading my amoled nexus against another one with slcd.

I wrote about black text on white background. I.e. typical web page or email, where black pixels typically are in single digit percent area. In this case amoled easily consumes more than double of the LCD power.
Watching movie is very different, where average pixel luminance is just a fraction of that.
If you want technical details look here, around the page 17:
http://data.4dsystems.com.au/downloads/micro-OLED/Docs/4D_AMOLED_Presentation.pdf
Don't know about you, but I almost never watch anything more than random youtube clip once in one or two months. So this advantage is totally irrelevant to me.
But I often use my email or read something up in the web, so that power consumption really hurts. It is actually the difference between "oh, ****, battery is already empty and I have two more hours to go" and "enough for a work day".

I do not need any googles, I see those distinct pixels at a normal viewing distance (like 30-40cm). They are apparent enough to be noticeable every time I look at the screen. Every homogeneous area has that weird grainy texture. And I have just a normal vision.

Well SLCD tends to look better in the sunlight, but AMOLED's colors are much more accurate (especially blacks, which look a lot like blues on SLCD).
Super AMOLED is the best of both worlds - decent performance in direct light, great, vivid colors. Too bad only Samsung's Galaxy S phones have SAMOLED displays.
Hopefully super amoled plus will be the best of all worlds. No more pentile

We know the differences between the technologies. What he's saying is that real world testing has shown otherwise. Engadget tested two Desires and the Amoled had better life. They even swapped batteries between the two phones and got the same results. There was another tech blog who tested Desires and found the same but its name escapes me right now.

Remains to be seen.
For example, the Nokia N8 has such a amoled display without pentile matrix. As far as I know produced by Samsung.
If this is an indication of what is coming, then I am not impressed. The color drizzle is gone, but weirdly enough there is a distinct red glow on the right side on the letters (white text on black bacground).

SAmoled looks better in the sunlight, have no "view angle" and got true black.

Because they tested it with the movie, which probably got a lot of dark scenes. Super Amoled very good with black color that doest eat the battery, but on full-white scene it consumes about 800mw. LCD - doesnt matter if it black, red or white - power consuming always about 240mw.
Notice that i talking about Super Amoled, because i didnt find any power test of standard amoled and as i know Superamoled is more power efficient than just amoled
Since almost all websites, sms screen and a lot of other things (MIUI rom for example, its almost complete in white) uses white background with black text, not a black background with white text, SLCD will be more better.

You have LED Displays confused with Plasma displays lol.
Plasma runs on gas fumes that burn images to its screen if its used in the same area for too long.
LED OLED and AMOLED are perfect battery savers especially on black bacgrouns and with black text it saved loads of battery.
GSM recently did a preview and said this about the screen. And i'm sure they review tons of phones. Should shut up a lot of haters and doubters who most likely haven't even seen a pentile display =)
The hyperglazed plastic will not enjoy universal appeal, but that might not turn out to be too great a problem - all eyes will be on the screen anyway. It's huge, it's got beautiful colors and deep blacks, it's sharp, and in short it's the best display we've seen recently. As expected, the whole PenTile thing didn't prove to be a big issue and you'll have to have a 20/20 eyesight and look really carefully to even see it.

And in regards to the Hyperglaze
This layer helps mask some of the fingerprints and is actually decently grippy, so it's probably the best bit about the S III back

Real and objective reviews and opinion are only by real users, not "gsm portals" reviewers
GSM Arena are notoriously clueless, as are a lot of tech bloggers.

I've searched as much as I can on this. Despite the materials/construction, views on in-hand seem to be unanimously positive due to the rounded shape. Coupled with the placement of the power button I think this will be what makes me return my hox for this. I really doubt the display will be as good as the slcd2 (it's that good), but I hope it's close.
Since the time i got my first Nokia 6600 i have been following GSMarena reviews and opinions. I would have bought more than 10 phones since 6600 till my i9100 S2 based on their reviews and they never missed a shot. Their reviews exactly reflected the phone. Well, this is my personal opinion and i am not trying to generalize.

I would have bought more than 10 phones since 6600 till my i9100 S2 based on their reviews and they never missed a shot. Their reviews exactly reflected the phone. Well, this is my personal opinion and i am not trying to generalize.

I agree the guys and girls at GSM arena are non bias and usually accurate. Let's not discredited them just because they did not like some parts.
Overall a positive review.

Editorial aside, the news isn't all good. The good news is that the display's much brighter than the GN where it was a common complaint. The bad news is that it's not as bright as either the SGS2 or G-Note, especially at 50% brightness which is the most typical setting.

Something I'm more interested to hear about is battery life. If the gorilla glass is thinner it might make the phone more visible also. If the battery life is great even with %75 brightness and better than the HOX at %50 brightness lets say, then I don't really see a problem and could see different kinds of trade offs.
I myself don't run my phones at %100 brightness that often.

Even if the glass is thinner it doesn't make the screen "more or less" bright.
One place where the brightness on my SGS2 is on full ALL the time is outdoors (auto sensor) and in bright sun it's hard to see, which means the SGS3 will have worse viewing outdoors than the SGS2.
Do the numbers always translate into how beautiful a display is? Serious question Ive never really paid attention.

"Beautiful" is subjective. "Cd/m2" is not. I should have posted the link, sorry. There's also a sublink in the article that explains the testing methodology.

Battery life is one of the things that concerns me. If any of you used Vlingo on the SGS2 in "listen mode" it was a battery pig. S-Voice always listening has to have an impact. Same thing with all the sensors being alive 24/7 waiting for you to blink or move the phone. You can turn it all off but it kind of kills the sizzle of the phone. I'm guessing Samsung made the battery 2200mAh for a reason.

Having a thinner glass means a lot. If your visibility is improved then you don't need to tune up the brightness as much to see. The type of glass you use also can help our hurt visibility. Think of the glass as a diffuser, when light hits it, it will actually be reflected and diffused throughout the glass, this goes both ways from the monitor and outdoor lighting hitting the screen. By thinning the glass and changing he type of material the glass is made of you can drastically improve visibility. I mean look at the iPhone 4S (541 c^2/m) vs the Galaxy S1 (354 c^2/m) and if I'm not mistaken the Lumia 900 has a pentile (390 c^2/m)
http://www.phonearena.com/news/Noki...martphone-crown-in-outdoor-visibility_id29918
Everyone assumes the Galaxy Nexus and SGS3 are the exact screens, but the way they look is not going to be the same at all. The screen itself is reported to be a bit different as you can see they have different brightness ratings. In addition, the SGS3 is sporting Gorilla Glass 2. Being brighter and having Gorilla Glass 2 will surely bump it up from the Galaxy Nexus screen. But we'll have to wait and see.
I'm sure there are a lot more factors as to what improves what and that's why the engineers went with what they did. In the end the screen probably won't beat the HOS in sharpness and will probably not be as good outdoor but it will be good enough in those areas and better in other areas like contrast. We'll have to wait and see more test done with the device.
Putting all the above aside, Samsung went with the SAMOLED because it helps them make thinner phones in addition to gorilla glass 2 being thinner it probably helped with the foot print in the unit itself to give us the SD card and removable battery and maintain the thinness of the device.

But wouldn't the scope he used to perform the test have netted all the variables out? Unless the test he's using perceives brightness differently than the human eye I'd think the comparisons would be relevant? No?
As for thickness of the glass, it's based on application and ranges from .5MM to 2MM. 2 is 20% thinner than 1 which doesn't seem that meaninful in terms of improved device packaging.
As an engineer, you'll find these interesting. They're way over my head.

Just a minor correction, the Lumia 900 uses an RGB stripe, not PenTile (I assume it's the exact same SAMOLED+ panel that was introduced with the I9100). The Lumia 800 has a smaller, PenTile screen.
About the Lumia's outdoor visibility, it's a result of their "ClearBlack" tech, which is a couple of polarizing filters behind the glass to reduce reflections of outside objects. Of course, thinner glass in the form of Gorilla Glass 2 should help as well.
My main hope is that what reviewers have said about the screen being better than the Nexus is true, especially that the usual PenTile graininess is less visible. I'm sure that the LCD2 on the HOX will remain the superior screen quantitatively, in terms of luminance and color reproduction, but that is not the whole story.

I'm not sure how the apertures work and measure things, visibility of the screen, light coming from the monitor and how the aperture works itself can all be different variables to be measured separately. If it bypasses through the glass and measures off the the panel itself or does it take into account the glass.
Like the test with the Lumia, Galaxy and iPhone. The brightness was measured seprrately and the visibility factor was done by controlling the environment itself by exposing the phones to different exterior brightness levels. They are actually determining outdoor visibility with photography rather than using an aperture, scope or device. So that I believe shows that brightness and outdoor viability should be independent of each other as they were controlled differently.
I had modified my original post to add this about how I have seen glass affect the military displays. "Think of the glass as a diffuser, when light hits it, it will actually be reflected and diffused throughout the glass, this goes both ways from the monitor and outdoor lighting hitting the screen. By thinning the glass and changing he type of material the glass is made of you can drastically improve visibility." There's also other factors such as how the glass is chemically cleaned on the surface and what kind of finish they add to the surface itself.
I wish I could answer more questions but I only have about 1.5 years of experience in this field as I was working on consumer products with no displays beforehand. I will take a look at those links after I eat dinner. Thank you, I've been looking for the test procedures of the gorilla glass.

Numbers does reflect how beautiful a display will be. But it won't matter to most of average users like me. In fact, I never pay to much attention on the screen to avoid over stress my eyes.

I would have to agree with you for the most part. I currently own the ipad 3 and the GS1. When it comes to text and sharpness, there is no challenge, ipad 3 owns my gs1. But in terms of pictures and videos, even my humble GS1 screens owns the lcd on my ipad (both made by samsung)
In the case of the GS3, it has a HD 720P over 300PPI. Texts will be crystal clear and sharp all the while giving me superior amoled video and picture qualities. Thats why I will never own another lcd screen given a choice. (didn't really have a choice with a tablet since ipad 3 was the best tablet to get)
Have you seen the 500px app on an amoled? It's freakin amazing. Much more than on my ipad 3. I doubt One X has a better screen than ipad 3 which has some serious color spectrum coverage.
As far as i'm aware the GS3 gas the same screen tech as the Galaxy Nexus, only that it's a little bit bigger. Does this mean that we can expect the same "burn in" issues as well...

I created this thread specifically for all the members to talk about the new 2k screen of the LG G3. The screen is the most important feature of the LG G3 and it is what LG brags about the most. For many of us including me, the screen will be the deciding factor of whether we buy the phone or not.How does the new 2k display panel perform in real life situations compared to other high end phone display panels like the Galaxy S5 or HTC One M8? Let's have a nice dedicated thread to the most important feature on this phone.
Ideas to talk about:
•Contrast levels
•How your content looks on it
•Your thoughts of it compared to the previous display you had.
•Any weird issues? (Screen interlacing, ghost issues)
•Color production
•Do you find it nice and worthwhile?
•How are those BLACK LEVELS (Important!)
•Any heat issues with the screen?
•Good high and low brightness levels?
All of the above... Thinking of upgrading from a nexus 5...

Go to s5 ^^ it's too bright and too vibrant :laugh: (^^)
And ffs please, reviewers, don't simply declare that you can't distinguish individual pixels on 1080p as well as 2k and then conclude from that that the extra resolution doesn't make a difference. The question is: how do you subjectively experience visual items in 2k vs. 1080p--images, text, UI items, etc.. Past 325 dpi, a pixel is not an item, so it's irrelevant that you can't see one. Tons of those online reviews provide what the reviewer thinks their impression of the screen must be instead of the reviewer providing their true impression.

I don't like the s5. Various reasons but mainly the cover over the charging port and overall design.
I love my g2 but need more memory (64gb minimum). I am worried about the screen on the g3 but the reviewers all focus on the resolution but I want to hear from real users about the real world experience of the screen.
Many thanks in advance for any input from owners of the phone.
Great Arstechica review as usual

That cover on the S5 (my wife has one), is for water proofing and easily ripped off.
Personally, I could use a screen with less pixels and longer screen-on time. I consider the screen resolution to be a minus. My preference is less pixels and make it a 6", like the HTC One Max I just returned after a week.

Can't agree with you there. They did the same move as all the other reviewers where they presume that the inability to distinguish individual pixels automatically means people can't see any overall difference in image quality:
Even at point-blank range, it's hard to resolve a single pixel. 1080p screens are also beautiful, though, and when looking at the two, side-by-side, we aren't convinced the jump to 1440p is necessary. More pixels only matter if you can see them, and on a ~5-inch device, it's almost impossible to tell the difference between a 1080p screen and the 1440p screen of the G3.

That's why I asked above that any reviewers here avoid that particular groupthink and tell us how they actually experience 2k vs. 1080p.

I think the most important caveat is that hardly any apps will be optimized for 2k display when the phone finally arrives.

That's logical. But so is the idea that the human eye can't distinguish pixels at a density greater than 326dpi. So, yeah, it comes down to subjective judgment calls. In that case, I'm interested in the subjective point of view of people who actually have one of these devices and their actual experience. We already know how do deduce logically what everyone's experience must be, and all the reviews I've read only do that. Images and text may appear sharper at a given distance from the eye in a way unrelated to whether or not you can distinguish an individual pixel.
The LG G3 has the best smartphone display I've seen: It's sharp, but it's also bright and has great color. The colors don't pop quite as much as on some of the better SuperAMOLED screens I've seen (such as on the just-announced Samsung Galaxy Tab S), but the sharpness is off the charts.
Comparing the G3's display to the one on the HTC One M8 (my current favorite Android phone), I felt the LG's was just as sharp, and a few details — such as drop shadows in Evernote — stood out slightly more. And even though colors weren't as vivid as on the HTC, the G3 had more natural skin tones

From Mashable's review. Everyone's eyes are different I guess.
Contrast was superb. Black text on white background — one of the most essential things a smartphone, or any display, needs to get right — really stood out. The ultra-sharp characters nearly jumped off the screen, and I couldn't discern individual pixels, no matter how close I put my eye to the screen.
So the LG G3's Quad HD display is more than just hype. But only a bit. There's nothing wrong with the HTC One M8's screen — or the Samsung Galaxy S5's or the iPhone 5S's for that matter. They're still mighty sharp, and can display great images, just not quite as sharply or as impressively as the LG G3.

I truly hope that the screen is great on this phone but I can't wait any longer and have just ordered an S5. I have waited for all the flagships to come out this year and was truly hoping that the G3 would be the one. Two of the most important things to me are brightness and battery life and I'm worried that with the G3 I would end up having the brightness cranked all the time and would have poor battery life as a result. Really wanted to try LG this time but lost my nerve
Tapped it!

yes but not for marketing.
I'm most concerned with the viewing angles, black levels, contrast, and color accuracy. I'm definitely getting the G3 but I really don't want to have to play the panel lottery. I'd prefer a warmer display over a cooler display - as long as it's not noticeably pink/green/blue, I'm fine. A slight yellow/orange tint is okay, but obviously a calibrated display would be the best. My black Nexus 5's viewing angles aren't great, with the screen washing out at 30+ degree angle. My buddy's white Nexus 5 seems to have better viewing angles, so I'm not sure what the deal is. I'm pretty confident in LG's ability to produce good displays -- they pretty much made this phone just to show off their new display.
Actually, I'm now concerned about the narrowness of the bezel. Yes, it's a cool feature, and everyone dreams of a bezel-less phone, but I already have problems due to the narrowness of my S4's bezel. When I'm holding my phone for an extended time, referring to notes while speaking to people, my grip often gets interpreted by the system as a touch and hold. That pops up a dialog that I have to dismiss, and it's really obtrusive in real time situations. Sure, I could be more careful, but it's just too easy to make that problem happen during normal usage. It's not like I have big fat hands or a weird grip or anything. I've already been thinking that when we finally get bezel-free phones, there will have to be utilities to create a non-reactive border of pixels in a user-specified width, or else the user will accidentally be popping things up all over the place. At present, though, I think the G3's large size and tiny bezel are actually going to make it difficult to use the way I want to use it even though it's hardly bigger than my S4. You never know until you actually use it for a few days and try to adapt, but there's no way to do that without buying it, which I'm now hesitant to do.
You're holding it wrong ☺

Introduction
If you own a OnePlus One and have kept up with news covering it, you should already be aware of the infamous "yellow tint/band/gradient/screen/tinge" (how many terms have been coined for this phenomenon?). If not, basically, it's an issue that has evidently plagued some* OnePlus Ones.
*I find that people can be generally divided into four camps:
All OnePlus Ones are perfect, the yellow tint doesn't exist
All OnePlus Ones are affected, none are perfect
Some^ OnePlus Ones are affected to different extents, but most are unaffected
Most^ OnePlus Ones are affected to different extents, but some are unaffected
^The proportion of affected vs. unaffected Ones is very unclear. Both of these cases are based on the fact that there are people who own OnePlus Ones that are completely fine, and the portion of affected users are the vocal minority.
I'm in the third camp. Mine has shown the tiniest bit of tint since day one (bottom 1/10th of the screen, more visible when looking down from above), remained unchanged after a month of owning it, and to this day remains unchanged as of the day before yesterday (17th December 2014).
SPOILER: 1 Month of Use

SPOILER: Day Before Yesterday
Pictured: @Aaahh's pretty neat software fix, turned off
I need to learn how to work the manual settings on my camera.
When displaying a prominently white screen/image/webpage, there is a visible yellow "tint" (let's just call it a tint for now) at the bottom of the screen that's "yellow-er" than the rest of the screen, right above where the capacitive buttons are. It is also the edge where the backlight LEDs are situated. Now, its severity depends from case to case, and often it doesn't really affect functionality, but it's there, when it shouldn't be.
OnePlus has kinda addressed this in two threads, but the conclusion was a bit ambiguous. The first thread thread addresses an "overall yellowish hue", and details how OnePlus sources panels from JDI, different factories have different batches, different screen temperatures, other flagship phones also suffer from this etc....and the second thread thread lines up the One with other phones and is seemingly normal.
As far as I know, "officially" speaking, this issue doesn't exist. People have RMA'ed their yellow tinted One (success? failure?), others who have purchased multiple Ones have the tint on all of them (at different extents, never subsided), and some other stuff. I couldn't keep track of it all.
So, knowing me, I downloaded the RAW files from the second aforementioned thread and checked the EXIF data. I'm sure their one wasn't affected, so it wasn't to determine whether the image was doctored. I just wanted to know all of the settings they used to take those two pictures, so I could replicate those shots. It's a good opportunity to try out my Canon 450D!
Note that the Canon 6D is a full frame camera, and the Canon 450D is a crop frame, so there's a crop factor difference of 1.6x. Full frames also capture more light than crop frames, among other differences like how the 450D is only 12.2 MP and doesn't have multi-segment metering...it was free though, so I can't complain :silly:
Picture 1: f/4, 1/125 s, ISO 100, 24-105 @ 47 mm, no flash, using Manual mode and multi-segment metering (+ a whole bunch of other stuff)
Picture 2: f/4, 1/25 s, ISO 320, 24-105 @ 50 mm, no flash, using aperture-priority AE and multi-segment metering
My attempt at replicating those pictures (to emulate the wider angle of a full frame, I used a 32 mm focal length instead of ~50 mm, which also changed the aperture from f/4 to f/4.5):
Left is unaltered original, right is messing around with levels
Picture 1: f/4.5, 1/125 s, ISO 100, 18-55 @ 32 mm, no flash, using manual mode and center-weighted average metering
Picture 2: f/4.5, 1/20 s, ISO 400, 18-55 @ 32 mm, no flash, using aperture-priority AE and center-weighted average metering
I'll see if I can upload my RAWs too.
Conclusion? I'm a noob at Photoshop/photography. But I can see why people alter the picture and take them at extreme angles; it's too hard to capture on camera. You see it with the naked eye, but it's really hard to capture what you see using a camera.
From the second thread:
Another thing to consider when seeing photos of the yellow band problem is that a lot of the photos were taken at extreme angles with Contrast and Levels changed for more visibility. We have been able to replicate some of the pictures posted here by playing with the Levels settings in Photoshop and the angle at which the picture was taken. We have attached the raw files and settings used to manipulate them in Photoshop below so you can download them and reproduce these images.
Some people have complained that their screen’s yellow hue is due to a “bad” batch. This is not true. JDI and OnePlus extensively test the quality of the screens, and while the factory hue of the screen may vary slightly by batch, we can recreate the level of “yellowness” through software changes.

Interactive part! To those who have a yellow tint that's more visible than mine, take a picture of it and post it below.
Different Circumstances?
Yes, I am aware that the screen temperature variation and unevenly diffused backlight/yellow band issue plagues not only the OnePlus One. This will be covered in the posts after this one.
In OnePlus' first explanation thread, some points were made; OnePlus deliberately chooses warmer displays for aesthetics, different batches have varying color temperatures, the latest CM11S update (as of 21 June 2014) is calibrated to be warmer to avoid fatigue, and we are reassured that this can be rectified through software.
I think not all Ones have a distinctively warmer display (I must've missed that warmer displays window), because my One's display looked pretty cool on CM11S 38R, and still looks pretty cool on PA 4.6 Beta 6 at stock settings (PA doesn't have any options to change the tone of the screen) when compared with the iPhone 6+. Say what you will about Apple, but the iPhone 6 Plus makes a great reference display device, because it's factory calibrated to full sRGB standards (quoting an Apple Store Genius (lol) and Apple's specs page).
Here's the iPhone 6 vs. the OPO on LiquidSmooth Lollipop:
Since PA is not CM11S, it doesn’t have a default warm screen temperature bias. I have been told that PA uses a "stock" color profile. Whether this is stock CM11S or stock AOSP I'm not sure. I will flash 44S (edit: probably not) on my One whenever I can. I wish I hadn’t encrypted it. In order to remove the encryption, the whole internal storage (all my stuff and the system) has to be wiped too, and I'm having difficulty backing up the contents. (encryption works on PA 4.6 for the OPO btw, but only use it if you really need it; TWRP doesn't get themed if you encrypt the phone)
After occasionally looking into it on-and-off and not really yielding any definitive results, it can be deduced that there are a few main possibilities that may contribute to this yellow tint:
The backlight LEDs were placed too close to the visible display area of the LCD, so the light didn't have enough room to fully diffuse before becoming visible, resulting in the yellow tint ("the "all ones are affected" camp)
Due to high demand and low supply, the factory at which the screens were produced were forced to ramp up production, rushing the LOCA curing process, resulting in some phones having "undercooked" displays that have a yellow tint localized at the bottom portion (the "some Ones are affected" camp)
Something could be up with the actual backlight diffuser in the LCD
A combination of 1 and 2, because the tint is coincidentally localized where the backlight LEDs are
Heresy
I will try and investigate the validity of possibilities 1, 2, and 3 (3 mightn't be by me, because I don't have access to an OPO LCD that can be dismantled). I can't do anything about number 5.
Possibility 1: Backlight Placement
This was explained by a OnePlus team member:
1. Our fans have also brought up a yellow band the bottom of the screen fearing it may be a quality issue. It is not. Since brightness influences color temperature, the yellow tint at the bottom is due to the design of the phone. There are 14 backlights under the screen, which were not meant to be uniformly distributed along the screen but to be all at the bottom. Since we needed to make the screen shorter, the lights were put very closely to the edge. If we didn’t, we’d have a leakage of light.

We are assuming this is a design characteristic (the "all Ones are affected" camp). I thought the bolded part sounded weird, because if the LEDs were placed further from the edge, wouldn't those 14 visible spots be hidden from view?
Also, after some quick Googling, apparently:
Brightness is a human perception, and luminance is an objective measurement
Brightness ≠ luminance
Color temperature affects brightness, not the other way round
That powerpoint was for entertainment lighting systems though, and it didn't specify whether the brightness and color temperature thing applied to halogens or LEDs.
The HTC One X/XL has a very similar display backlight configuration to that of the OnePlus One. The backlight array starts from the bottom edge, and it also has three backlit capacitive buttons.
The difference is the HTC One X/L's backlight diffuser extends over the capacitive buttons (requiring extension things to provide button backlight), and the OnePlus One's extends over it not as much (those white bits allow light to shine through the capacitive buttons, see two pictures ago).
Also, the back of the LCD is stuck on the chassis, making removal without damaging the LCD very difficult (more difficult than the OnePlus One). This one broke when it was removed from the frame
For this investigation, I'm going to measure the lengths of the screen bezel on the side where the backlight LEDs are (from where the display area ends to the edge of the glass), and from where the backlight diffuser assembly ends to the edge of the glass. Subtracting the second measurement from the first measurement will give us the distance that the backlight has before its light can be seen through the LCD.
Note: the accuracy of the measurements below aren't guaranteed.
OnePlus One
12.94 - 6.63 = 6.31 mm from end of backlight to visible display area
Sony Xperia Z
15.44 - 9.02 = 6.42 mm from end of backlight to visible display area
LG Nexus 5
14.96 - 9.56 = 5.4 mm from end of backlight to visible display area
Motorola Moto G (1st gen)
18.23 - 8.77 = 9.46 mm from end of backlight to visible display area
HTC One M4 Mini
10.81 - 2.83 = 7.98 mm from end of backlight to visible display area
iPhone 5
15.68 - 11.01 = 4.67 mm from end of backlight to visible display area
Apple iPhone 4S
19.71 - 14.12 = 5.59 mm from end of backlight to visible display area
LG G2
10.80 - 5.58 = 5.22 mm from end of backlight to visible display area
I don't think the measurements were very accurate, but from what we've got, the placement of the backlight LEDs shouldn't alter the color temperature of the display. The OnePlus One's placement is on-par with other phones' placement, so those spots may be more of a diffuser problem.
Possibility 2: Under-cured LOCA (Liquid Optical Clear Adhesive)
This possibility was speculated by users, and was not addressed by OnePlus. It has been said that exposing the OnePlus One's display to UV light or sunlight (apparently, 5-10 minutes in UV, 1-2 hours in sun) completes the curing process, thereby eliminating the tint. (will find sources when I have the time, it has also been said that this doesn't fix the tint/band)
Edit: might as well try the sunlight fix. I'd actually have to buy the UV lamps, and wait for them to post. Since my tint is barely noticeable, it's worth a shot. Bottoms up!
Looks like it did make a little difference! (or it might just be my mind playing tricks on me + wishful thinking)
We are assuming this is manufacturing process related ("some Ones are affected" camp). This would imply it is a QC issue, which it is not, according to OnePlus.
Samsung?
It has been noted that some Samsungs may suffer from unevenly cured LOCA. I have yet to see this for myself, but that's not to say it doesn't exist.
By design, Samsung's Super AMOLED panels have no discrete backlight; each individual pixel emits its own light. That's why dark/black images save power, and bright/white images consume more. Due to the nature of OLEDs, blue subpixels age faster than red and green, so the PenTile subpixel configuration aims to compensate for this by having twice as many (but smaller) blue subpixels than the rest. PenTile displays may exhibit a slightlu cool/blue tint as a result. An aged AMOLED display may exhibit a yellowish tint, due to the deficiency of blue.
Every generation has introduced upgrades and improvements to continually improve AMOLED tech. The Galaxy S5 and Note 4's displays finally outshine LCDs of the same class in terms of color accuracy/gamut, contrast, power efficiency, and uniformity of luminance. Sharpness has become increasingly irrelevant, thanks to the 500+ ppi of the Note 4. Any claims that LCD is objectively superior to the current generation of Samsung AMOLEDs is purely subjective. The only advantage that LCD has is its increased durability and lower price. They are less likely to fracture/crack and render the whole display useless.
I will get a phone that does not have a laminated display, and intentionally leave part of the LOCA uncured/under-cured in an attempt to replicate the tint where the backlight LEDs are.
How would this happen at the factory? I'd like to think the curing process involves a conveyor belt pizza-oven like device that "bakes" the display under UV light, but who knows!
We could ask Apple, since their iPhone 4 suffered from a similar problem
Update!: I think I should wear sunglasses next time.
I "only" put it in the lamp for 2 minutes, because that's how long the built-in timer is, and apparently some 20W UV lamps can fully cure a particular LOCA in a mere 6 seconds. I didn't want to risk damage to the LCD, so you could say I "chickened out"...
You can come to your own conclusions about what this means
In all seriousness, my One's probably not the best "poster child" for this, because I've actually heated the screen enough to separate the factory bond with the chassis, and exposed it to sunlight uninterrupted. We'll probably get more visible results by doing the curing process from scratch.
Pictured below is the phone in question; an iPhone 5S knockoff. Most of the better Chinese no-brand/knockoff phones have an OGS display (One Glass Solution), which is already laminated. It is like the OnePlus One's ToL (Touch on Lens), but not. I've posted on XDA before about it!
LOCA time!
As it turns out, the LCD is stuck to the front glass with adhesive tape all around the border. I didn't remove all of it, which resulted in some of the air bubbles to have nowhere to go
Get the display all clean, and apply the glue in an elongated "X" fashion:
I didn't have one of these:
So I used the phone's chassis. Bad idea. The glue leaked all over the place. The whole idea of the alignment frame thing above is to allow air bubbles and excess glue to escape, while also maintaining a uniform thickness between the glass and the LCD.
Lookin' good! This was the best I could make it. An autoclave would've came in handy.
Into the manicure UV lamp for 2 minutes. That should be inadequate enough!
The glue had already solidified enough such that air bubbles could no longer move around freely. The bubble in the top right corner became bigger, but other than that, everything went better than expected!
...or so I thought. LOCA had leaked underneath the LCD and into the backlight, because I used the chassis as the alignment frame, but it did not allow glue to escape.
The glue did not become yellow. It wasn't yellow when it was in liquid form, and I don't have much idea how long you're supposed to cure it for. Maybe it yellows further down the road?
Well, at least the properly laminated areas look great, and glare has been reduced. In hindsight, I should have used a display that could be replaced if I messed up this process.
¯\_(ツ)_/¯
This process is not going well with the Galaxy S3 display
If only I had gotten that $600 machine that make this process a whole lot easier (the frame laminator bit), or the lot for $4,250...
Conclusion?
We cannot come to a definitive conclusion at this point. The backlight placement doesn't seem to result in the yellowing, and neither does under-cured LOCA, since it yellows in a different fashion. Something's probably up with the design of the display itself, and it might have something to do with the color shift you see when viewing it from a different angle.
Either that, or like the touchscreen issues, there might be multiple causes of the yellowing.
Omg man, you deserve the crown of the unofficial Oneplus hardware development.
I'm so lucky to not suffer this problem (but i'm going crazy by the unresponsiveness of my touchscreen).
/p/ says your problem is that your using cannon I' just teasing man, this is an awesome post and we appreciate your efforts.
The complete yellower screen thing is really a color profile(ak has the old one, see the difference)
The tint 92% in the UK

The display may have been deliberately designed that way, but changing the colors counteracts anything out of ordinary.
In fact, I like it better than the Samsung and HTC, there screens look colorless or flat. I like my screen, it has depth

Are you kidding me? Samsung screens are extremely saturated? That's pretty much their thing, over saturating their screens.

I have to agree here, the saturation on Samsung displays is ridiculous.

If we're talking color depth, Samsung definitely has the upper hand over the OPO and HTC.

The S4 Active had a terrible display. It is not representative of Samsung's better displays.
I wouldn't say HTCs are dark. In fact, the HTC One M8 has a brighter than average display. Some OEM screen assemblies can be complete crap though.

It's just more accurate/has a wider color gamut that what you're used to on other phones.
Take a look at some of DisplayMate's Samsung display shoot-outs. The Galaxy S5 and Note 4 have some of the most accurate mobile displays on the market (not directly comparable with LCD tech).
He has a fix for that

I'm done fighting.
The Xiaomi Mi 9 SE has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!
This is the first time I use a phone that has Amoled screen. I heard about color shifting which happens to Amoled screen but I still curious. Does color shifting happen to your devices ?
For mine, when I tilt the phone, even a little bit, I see the blocks of color turn from blue (cool) to pink (warm) and backward. This only happens on white background. If the view angle is 90 degree, its fine. But if it greater or smaller than that, about 60 degree, it's just like a rainbow is moving. Kind of annoying

Please post some pictures of the display at different viewing angles.
Ive been using OLED screens for the last couple of years, mostly from Samsung, as is the one on the Mi 9 SE. They have never had any issue of the sort. I have however seen such a thing on the panels used in Blackberry phones.
The SE seems like the only device out this year that ticks my boxes as far as size and display quality, i would dearly like to know if sammy is delivering sub par screens here.
I have to say i am skeptical, so some proof would be appreciated.

Interesting. I've never used a phone with an amoled screen, but sounds like this would put me off.
Not sure if any stores here in the UK have the mi9se that I could try out before purchasing.
Pocophone I've just bought is lovely, but just a little too big for me coming from a mi6,which is why I'm considering the mi9 se.
No headphone socket though.!

Lets see if its actually true first. Here is a very detailed review that includes many angles on the display, none show any color shifting:

That review also has some interesting info about the notification handling and the state of the currently available ROMs.

Sorry about vid quality, I recorded it by RMN 3
You can see the color turn into warm and cool blocks when I change view angle vertically

it's hard to see much wrong with that.

Honestly I'm not seeing a big problem there... But the resolution isn't great. Someone below said the A50 display at the store was better but it too has an original Sammy screen, also manufactures in Vietnam.
Mb a good quality photo?
Also, what about the issue with the notifications? Ant solution for it other than AOD?

1 month used and I think I get use to it. Maybe after I checked Mi 8, it also has the same issue. So I guess this is actually not an issue anymore
I also hope for solution replacing notification light. Heard alot about "the dot" but after many attemps with many apps, the choosen one is still missing I guess.
I have a Pixel 3. The Mi 9 SE, despite technically having a lower PPI value, is noticeably sharper. I imagine this is because it's not using the Pentile layout that the Pixel 3 screen has.
