Everyone with a HD2 must have come from at least 1 resistive screen here, am I right? What do you prefer, resistive or capacitive? What are the benefits and faults of each? Which is more durable, and longer lasting?
Not necessarily longer lasting, but I would assume capacitive screens would be more resilient against day-to-day abuses.
I agree, more durability against scratches and such but what about breaking. Wouldn't a glass screen be easier to break than plastic?
Resistive screens:
+Precise
+Passive and stimulus-agnostic (stylus)
+Handwriting recognition
-Prone to scratching
-Plastic top layer distorts over time
-Difficult to implement effective multitouch
Capacitive screens:
+Responsive
+Easy to implement effective multitouch
+Can sit under glass; very durable and hardy, virtually scratchproof
-Active, requires bare or near-bare touch
-Prone to shattering
-Difficult to achieve precision (hitting those small x's)
After using the XPERIA X1, iPhone 3G and 3GS, Milestone, N97 and finally the HD2 it's capacitive for me all the way. I value a scratch-proof responsive screen much more than I do flexy, crappy (IMO) resistive screens.
Never had a resistive phone... 1st touch phone was the 1st gen iphone, and I could never deal with resistive after that... Kinda miss my g1 now that I think about it... But love my hD2
it would be nice if someone could invent a hybrid resistive/capacitive touch screen, have a thin plastic membrane over the glass for the resistive function
basically when the screen would sense pressure on the resistive touch screen it could check the capacitive sensor function of the screen to see if its a finger, if so shut off resistive and use the capacitive function to allow multi touch and better sensitivity for finger use.
However if the resistive layer of the screen senses pressure, but the capacitive layer picks up nothing, then it assumes a stylus is on the screen and just functions using the resistive layer
I dont see why this couldn't be done, the fact that we can put screen protectors on the screen shows that a plastic layer on the glass doesn't affect the capacitive function too badly, so you would basically have the capacitive sensors under the glass as is now, on top of the glass would be one layer of the resistive sandwich, and then put the plastic layer on top with the other layer of the resistive sandwich
My only gripe about the HD2 is not being able to use a stylus to take hand written notes in the office notes app like i used to be able to do on my old wizard. the huge screen would be perfect to be able to use as a notepad.
All the capacitive styli ive seen just look like blunt unsharpened pencils, they cant be terribly accurate for handwriting, though i have to admit i haven't tried one yet.

Dude, that's an absolutely awesome idea...and I suspect that the reason we don't have that isn't because it's not possible yet, but rather because it's not profitable yet Once it becomes a technology that either enough people will pay a premium for it, or it can be implemented cheaply enough to avoid a significant cost increase in production, we'll have it....or something that achieves the same thing anyway.
I would LOVE a capacitive + Wacom screen. The HD2 screen is big enough to be like a tablet and it'd be great to use a stylus with it. The finger goodness of capacitive with the precision of wacom. I miss being able to jot down notes on my iPaq hx4700.

Is it the same kind of touchscreen as all the other HTC models have or is it like the iPhone....
The onlu thing about the iphone is it's touch screen of hard glass coated with stuff to make it touch sensitive.
This looks to be hard glass too but it's very hard to see on video is there anybody who knows if it's hard glass or the same kind of touch screen as the Touch pro has...
Watskeburt,
Well the French chick in the video decribed the HD as having a better touchscreen than the diamond and it bieng almost as good as the Iphones. Although the Iphones touch screen is capacitive.
The Hd's touch screen is still pressure sensitive.
The HD's touch screen will be the same as the Diamond and Touch Pro. As the guy in the video was saying it was sensitive, he scrolled along the bottom of TF3D and it stopped going with his finger and treated it as a tap later down the line of icons. No touch screen can compare to a capacitive screen, the iPhone and G1 will always be more sensitive.
http://www.youtube.com/watch?v=Aiw5PsQ50Uc
Skip to like 1:25, as he says it's a very sensitive screen it doesn't even track his finger along the bottom.
The screen isn't multitouch compatible. if that's what you were asking.
No i was just wondering what kind of glass was used.
Is it lik ethe iPhone. Regular hardened glass with a touch sensitive coating ( that wears off after a while i know)
or is it the same old touchscreen that we are used to. You know sevral layers of thin glass and plastic that's so easy to scratch and break......
Well, "scratch" and "break" are relative, IMO. The iPhone's glass screen may have a more durable feel under normal finger usage but can shatter more easily when dropped, whereas plastics might feel cheaper but have a bit more give for better durability under sudden shock.
Resistance to scratches will depend wholly on the type of scratch abuse and choice of screen protector.
As far as the glass+capacitive coating (on the iPhone) goes, let me say that resistive touchscreens are also susceptible to damage, namely the "oil patch" where the touch-sensitive layer is subject to too much pressure and "breaks" (not immediately, but over time it loses its accuracy/sensitivity) and discoloration similar to an oil patch appears. This has happened to me on my Touch Pro, and others on their Diamonds, and I suspect it might happen on the HD as well (since it is also a flush-mounted touch-resistive display).
The capacitance screen of the iPhone also means it cannot be used with anything other than a finger, i.e. no stylus. This means that every interface has to be sized accordingly for finger user rather than being able to be smaller and more detailed for stylus use.
It's true that in the french video the menu scroller does not keep up with his finger. However, he is brushing the menu very lightly in order to demonstrate that the pressure threshold is much lower. No, it does not equal a capacitive screen, but he does specifically state that it is different to that of the diamond in terms of sensitivity. The diamond requires a lot of pressure, and you don't need a capacitive screen just to have it respond to much less pressure.
capacitance screen for winmo?
I wonder whether it would be possible for a capacitance screen to work with WinMo? I am massively jealous of the easy usability of my friend's iPhone, but at the end of the day, I use winmo programs. Capacitance screens feels like a superior technology - it just works better with your fingers

I disagree about the superior technology. As was said earlier in this thread you can't use a stylus witha captive screen or gloved fingers come to think about it. What about a combination of the 2, that would be superior tech.
I can tell you that the screen is really great. better than i thought.
It is still a resitive screen, but it feels like glass, especially after you put the screen protector which comes with the device on the screen. an as far as it goes, i think its very scratch resistent, even against fingernails and so.
It doesn't even feel like you are pressign the screen, its much more like the iphone glass display and comes very close to it.

Ok Ok. You can use a stylus with a capacitive screen but it has to be charged i.e produce electrons. On HTC devices you can use anything thats at hand.
Like i said before i like the feeling of a capacitive screen but it does lack in key areas. A combination of the 2 screens would be the future, but i'm sure there are technical limitations to such a project.

I wear leather gloves when it is cold and I am happy that I would not need to take them off to use my phone and freeze my fingers when outside. I have seen iphone users wearing gloves taking them off to use the phone. I guess another perk to using pressure sensitive screen - warmer hands
seeing no body answered OP's question, but all came at a very close tangent, i'll take a stab at it.
HD's screen is not glass, it cannot be glass like iphone because HD requires it screen to "bend" and "depress" a little at the specific spot so the second layer can sense the pressure. the first//top layer is only a screen, touch/pressure panel is beneath that.
do you definitely need to put a screen protector on or is it going to be pretty scratch resistant without?

I didn't test ist without the screen protector (but the one which is in the package is very good and invisible, as the edges are perfectly cut.)
With the Screen protector of the packages, it seems very scratch resistant and fells like the glass iphone screen
did the screen protector go on easy or do you have the bubbling problem?, this is the main reason i dont bother with screen protectors.
Before I got my HD2, all I read was that iphones dont work with gloves due to the capacitive screen, I thought bummer when it snows here the same will apply to the HD2.
Having just come from a snowball fight, and taken loads of pics in the process, I was surprised that I could whith my huge thick gloves.
My question is, is this the same for all capactive screens?
maybe this is the reason why the touch screen doesn't work proper in many cases - it's too sensible, there is a too big electric field, therefore when using the virtual keyboard it happens that an other letter is displayed on the screen than you've pressed.
Just a thought but...... won't the tip of woolly/cotton gloves scratch the screen?
Well, mine sure doesn't. And I wish it would! I go to work on my bike and this is the season where I have to wear thick gloves. I'm afflicted like many of us by the "music stops" bug and I have to stop, take off my gloves and starts the player again. It's a pain!
It depends on the material of your gloves. As I mentioned in my tips thread, thin leather gloves DO work on capacitive screens such as HD2 and iPhone. However I also have another pair of leather gloves which have like a knitted wool lining which is quite thick (the lining not the leather) and was suprised to see them work too. I think it is probably because the wool lining holds the static from my finger that allows it to work. I think. I am not an expert in how capacitive screens work. I can happily type an sms without having to remove my gloves in this cold snowy weather.
Generally the thinner the glove material the better. Don't waste your money on these special capacitive finger tip gloves. There are far more better looking gloves out there. Just choose thin leather gloves to be certain they will work.
Should have mentioned that these arnt woolly but polyester with a thick inner lining,
Maybe its the reason for all those extra diagonal lines on the screen??

conductive thread
today i received about a metre of conductive thread from ebay. (under 3 quid)
initial test show that this:
http://www.instructables.com/id/Making-A-Glove-Work-With-A-Touch-Screen/ is going to work really well.
my gloves are however massive so i'm going to get a higher quality, thinner pair and then with a few stitches i'll be nice and cosy.
Can i use scratch remover for plastic as Displex for polishing touch pro external screen?
I think the Displex site specifically says don't use their products for touchscreens.
I just checked on Google and some people have tried using it with good results (NO EXAMPLES FOR FUZE) on resistive touchscreens. Because it removes material it may change the touch properties at the spot being polished or may mess it up completely.

thx but i think touch pro's screen is different than other touchscreens.
i think it is similar to htc touch and it has two separate screen parts (screen and touch panel).
i don't know... yet...
i've send email to displex manufacturer (now in Germany) and asked them about this, in detail .but only response i got is : "we do not have application for that". I don't know what they meant...
Display isn't different say between a FUZE/TouchPro Kaiser or TYTN. All resitive - pressure triggers event. Tilt2 still uses same technology. Capacitive is whats in the TOUCH HD2 or Apple Iphone. Uses a piece of glass to detect current not pressure which I think still has some coating on the glass.
The resistive uses pressure points in the digitizer. Displex or any polish removes a slight amount of material from the plastic so the resistive capabilities may be different in certain sections versus others. Calibration won't help because the thickness won't be uniform in theory.
If the screen is pretty bad you could try it although I've seen sites where someone has used it and messed up his touchscreen. There is also something called iDrops which polishes the Apple's screen/case. Someone on the Kaiser board attempted to use it and it worked without messing up the screen. I think Displex may just be too harsh.
Displex sucks...

Displex does not work, It didnt damage my screen but it didnt remove the scratches either, didnt even change them i used a whole tube on my screen still all the scratches were there (I didnt scratch it I bought it used =D). Also tried it on my brothers Nokia which is not a touch screen he has loads of those really light scuff scratches and it still didnt work? So yeah its a wate of money.
displex is a piece of ****.
It does not make less visible scrathes even on CD roms, plastic glasses watches and any type of mobile phone's housing lens.
It works a bit only on plastic housing because it can losly remove polish and paint.
Do not use it on housing more and more so no losses of clour you live. But try it any type of plastic or plastic covered screens.
Do not try it on glass so do not try it on capacitive screen because dottes and scrathes become more visible (rainbow effect).
I know we are waiting to see about the gorila glass thing, but I read on a forum that it had capacitive touch... I'm not sure what that means, can some one explain to me? Looking at the Toshiba screen+ thing I am inclined to think the Toshiba screen will be better... not saying that as a fact or anything...
gorilla glass is a glass developed by corning and is much stronger and scratch resistant than normal glass.
i'm not an expert, but I think that capacitive touchscreens uses electricity to sense a touch.
The transformer has both of those technologies, and I'm pretty sure that the Toshiba tablet also has a capacitive touchscreen, but not gorilla glass.
There are THREE type of "Touchscreens"
1.) Laser grid ( example HP Touchsmart IQ series PC )
This type of touchscreen is actually NOT a touchscreen at all. It shoots out invisible lasers in a tight grid and see where the grid break when you put your finger on it.
2.) Resistive Touchscreens ( Example Nintendo DS and DSi and 3DS Series ) This touchscreen uses a type of pressure sensitive and very flimsy film to register and touch. This type of touchscreen is the cheapest option available and as a result are VERY crappy for gaming console and the like. However some WACOM devices use it perfectly for drawing and such.
3.) Capacitive Touchscreens ( example....Asus Transformer and most of all tablets these days ) This is the BEST type of touchscreen. With sensors that detect where you touch by measuring electricity from our bodies. This is the smart choice for all devices these days.
Hope that helps you out....and yes the TF has Gorilla Glass.
thanks!!!!
I also read in a review that the Thrive's LCD is nowhere as good as the Transformer's.
What review? I thought the tablet wasn't even out yet?

Just a point of clarification on point 2....
Resistive screens are not bad at all. In fact, they have better accuracy, b/c they are meant to be used with a stylus (a slim point). Whereas capacitive screens expect fat fingers, which make them feel better when not using a stylus.
The very obvious benefit to capacitive screens have the glass up front, vs. the touch layer being up front on resistive screens.
-bZj
Also, capacitive touch screens aren't very good with stylus input (handwriting) because your hand will trigger the input too. So you'll either have to hover your hand while writing or wear a glove, or pull your sleeve down over your hand.

For those that are wondering about what handwriting on the Galaxy Note 10.1 is like, here's a sample of one page of text from the Papyrus app handwritten by me. I was writing pretty fast and I know my handwriting is not the best but I did it like that to prove that the active digitizer works quite well. This also gives you an idea of how much text you can actually fit on a screen. Of course, you can zoom out and pan around to fit more but I think that's incredibly annoying for writing (but for drawing diagrams it'd probably be great).

This is excelent. I've been writing with capacitive stylus (Adonit Jot) and I wouldn't be able to write nowhere near that good with it (while for a capacitive stylus it's pretty good). I wonder why we don't see such writing in reviews... Also a question: doesn't the stylus slide a little because of the glass? Wouldn't it be better with a matte screen protector so it has some resistance?

Thanks! Yeah, when I was reading all the reviews I didn't understand why no one thought to do this, instead we get the random drawings and one line sentences. The stylus should be the focal point of the review for a device such as the Note.
Yes, the stylus definitely slides because of the glass. I actually used to use an HP tablet PC about 4 years ago and it had a similar feel (although it wasn't as smooth because it had a resistive touchscreen layer instead of capacitive glass), and I think you do sort of get used to it. However, I think you can get Wacom styluses with felt tips or something like that so that you get a little more resistance, and as you said a matte screen protector would definitely make it better too (and is probably the best solution). I haven't tried one yet though. It's not the same feel as paper but I think it's not really bad, just not the same feel, and you could get used to it.
