Hi,
Ok first of all i know that there are other threads related to this thing, those threads defined the problem and many posts were speculations and wondering wither its hardware/software/glitch .... etc
As i was searching about this and saw the other members conclusions I wanted to start a new thread so any new member comes and read this and know exactly why is this happening to him/her, and wither its a real problem or not.
Desire's AMOLED displays have a big resolution 480*800 pixels,and have different sub-pixels arrangement in it, each pixel have "RedGreen" and the one after it is "BlueGreen" .... RG BG RG BG, .. etc, that is PenTile Matrix, while other LCD and "normal" displays have RGB RGB RGB, ... etc
for more info about this, click here
the pentile matrix looks exactly like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now the effect of this matrix is double edged, instead of having 3 sub-pixels in each pixel, we have 2 sub-pixels in each pixel, this saves power, precious battery power, but also this arrangement of sub pixels contributes to the issue somehow because the colors will not "look" exactly the way they are (the way the RGB matrix show it, which is used in most of our displays like TV, PC, LAPTOP, ... etc), there will be slight difference due to the screen "approximation", and that difference is NOT noticeable in most cases, only in few cases where the solid colors intersects with each other.
see the posted screenshot of Gmail app with the gradient color near it
see how the color picker identified the gray color, .. and how close it is to the pink, the pink showed due to the display approximation of the color.
and most importantly see how "photohop" saw the color as "not a web safe color" and see how it showed in the small square the pink color!
photoshop detects this because it knows that if an "approximation" happens than this will be displayed as pink.
And not only that, photoshop suggests that you put a "safe" color, and it shows "pink" instead of the gray as a suggestion!! why is that?
To find the answer, look at the circle in the color gradient board, you will see that this "gray" is nearer to the pink than it is to the actual gray!!!
and here we are seeing it pink on the Desire's AMOLED devices, what a surprise!
Now notice how the upper bar is dead gray, and does not have any pink in it, that is because its "GRAY" is not close or near any other visually-different color. and of course photoshop identified it as "SAFE for web", and that even if an approximation happens, this will still be rendered as gray
the good news is, it will NOT be noticeable in most of the cases, because most of the colors are not gray scaled and not "visually close to the human eye" to other colors, as you can see from the gradient color posted there are many "safe" grays out there, ... but google had to choose that gray that is near the pink
Now the bad news is, that this is NOT an android software problem, it is a hardware (display/calibration) issue.
but does that mean it cannot be solved "indirectly" by software? .... not sure, am thinking of what if Android created a layer where it picks each color and see wither its safe or not, .. if its not safe than do an OS approximation for that color, if its "gray near pink" change it to "gray" and pass it to the AMOLED as "safe color". not sure how that would be implemented or what is the weight and impact.
but as i mentioned before, if apps stick to "safe" colors, this will insure that even if an approximation happened, nothing will be noticeable
------------
UPDATE For people who think that the issue is from the browser and not from the AMOLED display that has PenTile matrix.
here is a screenshot from Android SDK emulator with the same browser as in Desire (WebKit)
here is a screen shot of the original website from the PC, using Google Chrome browser
and here is a screenshot of the site taken directly from HTC Desire (the site has been visited from the HTC Desire and a screenshot was taken and transfered)
Its pretty clear that the browser is not the real issue (even though it has some slight very slight pinkish hue), the pinkish is alot worst in the desire than what is the emulator and the screenshots show
-------------
UPDATE
After seeing the below pictures (thanx onkolog for posting those pics!), one can conclude that this "gray shades to strong pinkishness" issue is definitly not a general AMOLED issue.
People reported that in Samsung Galaxy, and Legend (Both AMOLED but not PenTile matrix) have slight pink viewing the htc.com site, but it is nowhere as pink as found in the HTC Desire
HTC Desire:
HTC Legend
as the pictures shows clearly that the legend (which has AMOLED display with normal RGB implementation) shows the Gray as pretty Gray (not as pink as the Desire).
here is a pic of the Desire & Legend side-by-side with the HTC website shown
(thank you ohyeahar for this shoot). the Desire has more pinkishness than the legend, the legend seems fine but some people said that it also has some slight pink (not as desire though)
as you can from the photo and as ohyeahar stated (having both devices, legend and desire) that its not a real issue, but its there if you really look for troubles you will find it, otherwise normally you wouldnt be annoyed from it
EDIT: some people have pink hue all over the screen, not only particular apps/colors, .. IMO this just your device, and you should replace your device
EDIT: I used web-safe colours as a technique to show how the colours might look different due to screen approximation the web-safe colours is not designed to detect the approximation of the Desire's AMOLED accurately, it is designed for web approximation due to compression, but they are similar some how, in terms of that colours are getting approximated and changed sometimes to the nearest possible colour thats why i used it.
the "web-safe" approximation only appears when an image is compressed for web standards (or approximated in case of the Desire's AMOLED), .. some images are not compressed for web use, you see the the HTC.com page gray on your monitor, and i see it gray on my nokia e75, but it looks pink in the Desire's AMOLED because the display of the desire (and i suspect android too) approximate the colour, and i used the web-safe colour technique to detect that (even though that this technique is not dedicated to identify the Desire's AMOLED approximation)
Thanks irkan for that. That goes a long way to explaining why we're getting this pink tint in the same screen when we can also see pure grey.
So, now, what can I/we do ... should we replace our Desires for new ones or not? I suppose there is no harm, just the inconvenience of setting it up again ...

as i mentioned in the last line, if you see those damn pink tints every where, than most probably your device is faulty, but if you only see them in GMail app and some few other occasions, than its just the display.
but you know what, if you still feel unsatisfied just go and replace it, setting up a new phone is a pleasure with the desire
It is quite disappointed ... I meant, the AMOLED and Pentile Matrix are suppose to improve battery life, but in fact the HTC Desire battery life is not that good.
Sure, it is not terrible. However, it is not satisfactory when you read from users testimony here:

And I hate seeing that pinkish color
Oh well, my first Android device ...
The battery drain from the screen is somewhat dependant on what you are watching. If you are displaying an image with lots of different colors, areas with black and so on, the screen will not use as much power as an LCD-screen. But if you for instance use a spreadsheat in excel or word-doc. where most of the screen is bright white, then the screen will use more power than an LCD, since it has to light up all pixels, whereas the LCD only has a few backlights.
As an exampel from a QVGA screen; black text on a white background would eat up 3W, white text on a black background would only use 0,7W.
So in real life, there might not be that much gain in powersaving.
Given that the HD2 has a 12% smaller battery and 35% more screen area than the Desire but similar battery life, I don't understand why the Desire needs an AMOLED screen that can't accurately reproduce some colours and doesn't have a true 800 x 480 resolution (more like 392*653 if you read the article linked in the first post).
seriously am i the only one that doesnt see a big difference here? i can hardly see the pink tinting. maybe if i look dead close to it i may see it but as long as its not soo obvious i wont be replacing my device.
nip picking springs to mind but anyways OP thanks for the information though.
I've just canceled my pre-order, no way I'm getting a device with a screen that distorts the colors.
This reminded me of the nexus one screen analysis made by Display Mate.

Have you tried visiting for example the htc.com homepage. As said in another post it looks like a totally different site.. Everything on it is pretty much pink! lol.

Yes i tried and it looks better on my desire actually. the colours are more warmer and sharper then on my TN dell pc monitor.
it is a tiny bit pink on the desire but its hard to tell because generaly TN panels are NOT accurate reproduction of the true colours.
matter of fact, OP did you try viewing that screen shot on a IPS panel monitor?
You guys do know TN panels do not reproduce accurate colours right lads? compare it to a ips panel and i bet you it is the same colour reproduction as the desire.
before slagging off the desire for having tinting issues, check it first. go to a apple store and use there mac to browse the htc website and see for yourselfs
Not slagging off.. Just want to make sure it is correct before I except it.. When i say it is pink i mean not far off the pink of this smilie . It isnt a faint pink which you can just pick out... It is pink.

Hello. Received my HTC Desire today (typing this post on this lovely device)
Unfortunately, I'm noticing a subtle pinkish display instead of white and wondering if anyone else is experiencing this?
This is my first AMOLED display and wondering if this is normal or have I got a faulty display and should get it replaced?
sounds like a faulty display, as you can see on many videos on youtube none of them are pinkish
if you have another camera (or phone with cam) try to take a pic of it and post it. ... it does sound strange never heard anyone complain about the display
The only pinkish thing on my phone is background in Google Mail app. But that's how it's supposed to be I guess.
If the screen brightness is turned to a minimum, there is a certainly visible pinkish tint to the screen. This isn't bothering me though as I don't ever plan to reduce the backlight to that level!

I think that pinkishness (now that's a word!) comes from overall theme colors. If you turn it down to the minimum and visit a while page on your browser it won't look pinkish. At least it doesn't to me.
Thanks everyone. Tried the suggestions and here's what happened.
If I turn down the brightness, the subtle pinkish display becomes very pinkish, definitely exaggerates the pink hue effect ...
If I turn up the brightness to full, the pinkish display disappears.
Here's the funny thing ... Google Mail definitely has a slight pink hue, regardless of what the brightness level is but in all other apps, it doesn't ...
So, fellow xda'ers ... should I replace it or not ...? I wish I could say the subtle pink hue doesn't bother me, but I can't help notice it in Google Mail (which also happens to be my number one, most used application).
Really, I need to know whether this is a fault (or the start of this display becoming 'more' faulty) or just something that AMOLED displays generally exhibit ...
Your thoughts are much appreciated, as always ...

I would still recommend you take a pic of the screen in "normal" brightness and post it, .. that way every one can see and compare it to their own device (preferably use stock wallpaper).
This happens on the Nexus One too. There is nothing to be concerned about.

Think hue you see is probably due to a characteristic of the amoled used in the Desire (and Nexus One). Have a read here.
I get this too I just assumed it was due to the AMOLED screen.

No i think his issue is something different, .. as he is noticing it on the pictures also not only text, ... (text is mostly effected because usually the black and white intersects, thast where the problem appears). however in the pictures, there should not be a problem (unless if this picture is black/white ofcourse)
I have this too, and I have two Desires - it only appears on one of them, so not all machines are the same. See my post new post from this morning.

It's NOT serious. In fact you could say the pinkish one is slightly warmer (which many people prefer), leaving the other machine looking slightly blue and colder.
Unless the machines are side by side, you'd never notice. There is probably more difference between your desktop computer and your laptop.
i have a zune hd and that is amoled and there is not even a slight hint of pink, so this is not something to do with amoled as a technology in general.
Figured I'd post this, clearly pink hue in comparison to the iphone. However this is one of the only videos I've noticed it in
Hmm, cant post links as I'm new,
youtube.com/watch?v=Tbb1b3AXOGs
Yes, just wanted to post that one. I found another one.
Funny thing is that some devices have that effect, some of them hoesn 't (or effect is not visibile on video).
Hi, I really want to buy a Desire but when I tried it in a store I could easily notice the fuziness caused by the Pentile subpixel layout. This was on white text on a medium coloured background - I've read it's worst on black/white. I also looked at the Galaxy S and the fuzziness was much less noticable - I just hate the look and feel of that phone.
The problem is I have a pretty low tolerance to small details like that and pretty good eyesight, so I was wondering if anyone here is as anal about visual flaws as me but happily lives with the Desire's screen? I want my next phone purchace to last a couple of years at least...
I also thought it might be nice to wait and see if HTC release a Desire with a S-LCD screen - sharpness wins over deep blacks for me considering the other potential flaws with the AMOLED screens. Any thoughts?
(If the Wildfire had either an AMOLED RGB screen or a higher resolution LCD then I'd just settle for that - it looks sexy enough to live with the lack of power.)
any thoughts? eh, sure. I don't see the the "potential flaws" of AMOLED screens at all. Sure a true LCD display will have sharper definition for black on white text, but I hardly would clal my Desire screen blurred or fuzzy. I think its fine. I do a lot of reading on the net too and its absolutely fine, but you are right an LCD like iPhone is sharper for text.
I prefer the colours and the perfect blacks myself. Makes using the phone for watching movies etc a pleasure. If you use it just for very small text though, get something else. If your as picky as you seem, you will definitely have problems with this one with its amoled screen. I won't even mention the over saturated colours or the pink hue when viewing grays. You won't like that either.
i compared the screen on my desire to my friends new iphone 4 and honestly i could only tell the difference when i got so close it was physically hurting my eyes to focus on it, i really think that the screen on the desire is top and i dont seem to have much trouble with it in the daylight either for some reason
By potential flaws I meant the uneven & relatively fast fading and the burn in that some people are reporting.
I looked for the pink hue in the shop but couldn't notice it. Isn't that a hit or miss thing?
OLED is a major selling point for me. But then is resolution (<3 my x50v)
Anyone think the Desire with an S-LCD would be a big improvement?
Yeah, daylight didn't seem to be an issue at all, compared to other devices I've used over the years.
I definitely see a huge difference between Desire and iPhone 4 though. Desire is actually about on par with the previous iPhones in terms of actual blurryness, but the fact the pattern is staggered makes it more noticeable.

No the pink hue effects all AMOLED screens when displaying certain gray shades. I suggest you read the sticky post all about the AMOLED Pentile display and how it works.
Is the Desire available with S-LCD? If not, whats the point? Just get yourself a phone with LCD and be happy. The power drain on a desire with LCD would be significantly increased too. Sure AMOLED uses more on a 100% white screen, but it use much less on darker themed screens or coloured screens.
I've read the sticky and think I have a good grasp of the issue, but I've seen reports from people saying the pinkness varies.
I also have 20/20 vision and this screen is fine, the only times I'm disappointed is while text is scrolling there is a visable wave in the letters and outdoor in direct sunlight you need to find the good angle to read.

I used to be very anal about my phone. And of course you might be different but for me trying to choose the perfect one / making the perfect one ever more perfect just does not work. Huge effort, lots of frustration, little or no results and even the ones you get are brief. That's the problem with this attitude - you'll just always find another flaw to frown upon.
What worked for me was taking positive action rather than getting rid of all the faults. I implemented Allen's GTD system and I'm using my phone as a collection/organisation tool. Works great and now my phone is a very useful tool instead of being just a gadget. Flaws don't matter anymore. And with GTD I can be as anal as I only wish and still happy
BTW totally agree on Galaxy S. It's so much better phone than Desire but it's simply atrocious. Couldn't bear the thought of carrying something that makes me wanna puke for next 2/3 years.

Pink hue is not AMOLED related since it shows also in software emulator (on PC) and varies among phones. Sticky post is wrong all around but arguments for that are buried too deep in long thread.
AS for OP, HTC announced LCD Desire, and I would like to see one. I can notice PenTile artifacts and don't like it (together with over saturated colors and pink hue), but phone is so good in other segments it is worth owning.
Lots of anal talk in this thread!
Seriously, I have never seen the pink everyone is talking about and I have had my phone since the middle of april. It's weird that some phones are affected and some are not.

Yeah sure the screen has some negatives about it but when compared side to side to my old iPhone's screen its blows the iPhone out of the water. I prefer AMOLED because I can turn it up full brightness and not be blinded by an annoying backlight that make sthe phone more suitable as a flashlight than a screen.
I thought I replied earlier, but it seems Opera 10.60 is a little glitchy with the forum (and in general...)
Anyway, thanks for all the replies guys. On the way home I had a look at the Desire again in another store and found the screen a lot more agreeable. I tried it sitting down, making me naturally hold it a couple of inches farther away, which makes a big difference. Plus I had more of an "how nice is this display?" attitude rather than "can I notice the flaw?"
So I came home and ordered one online. If the text bugs me that much, I can always stick to my Axim for ebooks.
edit: Still eager to see what S-LCD brings to the table, though.
Apparently, S-LCD does not stand for 'Super LCD', it is just a name of Samsung-Sony LCD factory.

Did you know that PenTile OLED was in tens of thousands of cell phones for over a year before anyone noticed that they were different? If one has to be told that they are different... well that tells me that they work as designed.
Full Disclosure: I'm one of the inventors of PenTile technology.
PenTile technology was actually designed with a specific minimum distance from which to view it. Bring it too close to one's eyes, one will see the pattern. Actually the same thing also happens with the legacy RGB Stripe matrix, but since one is used to seeing that pattern, one mentally filters it out. The same should happen with the PenTile screen, once one is used to seeing it, one no longer "sees" it, if you can pardon my circular explanation, but it's true. If you use the phone at a more comfortable distance, as opposed to as close to your eyes as you can get, the screen will appear as intended.

I definitely would have noticed it if I didn't know in advance. (I'm not trying to imply there's anything good about extreme pickiness - it's a compulsive disorder and a bloody nightmare.)
I appreciate the minimum distance thing, but obviously it varies with eyesight - hence the brief controversy over Apple's 'retina' claims. It's just going to require a slight adjustment to my habits while standing to compensate for this.
As for the RGB thing, I feel that's easier to mentally filter out because it's consistent vertically whereas Pentile alternates the relatively larger red/blue subpixels. I imagine this is why the effect was less noticeable on the Galaxy S's RGBW layout, despite the slightly lower DPI?

As above, I think this is subjective. Some people stare at their phones looking for dust, looking for a hint of pink, looking for a mark in the case, looking for... etc etc etc... If you want to treat it like that you will be a very miserable camper. It's a phone, it has an average lifespan of 2 years probably. Use it. It reminds of these people who own a beautiful Ferrari but on't drive it. just keep it in a garage and rub it with a cloth. whats the point?
I think the only thing thats variable on the pink hue thing is the persons opinion of how pink it is. not noticeable or noticeable. some people will say its not there, some people will say it sso pink they cannot even see any other colours.
I had my eyes colour calibrated in a 16 hour operation at an optical lab in switzerland 4 weeks ago, they now recognise 400 shades of pink and have 20/20 vision, so I KNOW my phone has pink. etc etc LOL

So your saying the new forum theme doesn't look pink to you on your phone? All the grey bits around the forum are definitely pink in colour on mine. Maybe i have one of the affected phones.

The forum doesn't look at all pink on my phone, I've never seen this issue either.

Full Disclosure: I'm one of the inventors of PenTile technology.
PenTile technology was actually designed with a specific minimum distance from which to view it. Bring it too close to one's eyes, one will see the pattern. Actually the same thing also happens with the legacy RGB Stripe matrix, but since one is used to seeing that pattern, one mentally filters it out. The same should happen with the PenTile screen, once one is used to seeing it, one no longer "sees" it, if you can pardon my circular explanation, but it's true. If you use the phone at a more comfortable distance, as opposed to as close to your eyes as you can get, the screen will appear as intended.

Sorry, but all your arguments don't add up. On LCD screens i have perfectly straight horizontal and vertical lines, there is no need to filter out anything.
On PenTile displays i dont have straight lines because of the pattern that is used. THAT is the problem. Lines look like zigzag-lines not straight ones. And no i'm not looking at my phone from 1 cm distance, i'm looking at it from a normal distance and i can see the pentile effect on my Nexus One. I also had a Motorola Milestone which comes with an LCD that surpasses any AMOLED PenTile screen quality regarding resolution. (while both claim to have wvga)
There is a very easy test for this. Take a Motorola Droid and a Nexus One. Place them side by side and open a webpage on full zoomed out view. You will see the difference in resolution quality VERY clearly. Anybody who claims that there is no difference is lying. You can't just imply that the eye can't see an difference because there are many people out there with normal eyesight (i'm not talking about eagle eyes here) which see the pentile pattern too clearly.
The whole topic is quite frustrating because when buying a nexus one you make one step forward (generall hardware) and two steps back (pentile).
The phone also feels tangibly heavier.
Think it may be a Super LCD screen rather than AMOLED (how can I check?). Overall, the screen just looks grey. I want my old AMOLED one back?!
Some things to try:
- look at the screen through a circular polarisation filter, eg. RealD glasses (no idea if this works with SLCD...)
- set brightness to maximum and display a black image in a dark room
- look really closely at the screen with a magnifier (or someone with good eyesight) to see if it's Pentile (I guess an LCD screen could be Pentile too...)
- weigh the phone on some good scales to see if it really is any heavier
I've weighed it - and it's just a bit higher than 135 grams. Even though it matches the spec listed on HTC's website, I still think my previous phone was lighter. Now to test the AMOLED screen. Hmm..

the backlight is apparent then. when i switch the phone off, it goes completely black, otherwise it's a grey colour. does that mean it is not AMOLED?
It certainly sounds like that may be the case
Would you be able to post pictures? This is bad news for anyone wanting a replacement. AMOLED was a big selling point for me.
However,
Can you read it in daylight outdoors?

If it's LCD, can I have your Desire then? I hate the Pen-Tile pixel layout...
Seems the black wallpaper in the dark test isn't a valid avenue to test if it's AMOLED (see: http://forum.xda-developers.com/showthread.php?t=725656).
Think it may be either me just imagining things - or a defective AMOLED screen.
I'm sending my Desire for repair as I have dust under my screen, I contacted HTC support worried if I may get an LCD screen and they asured me they are currently still using AMOLED displays only
tell me if my screen looks washed out to you. I'm sure my last desire, the colours were a lot more vivid.
Can't really tell if it looks washed out in a photo with nothing to compare it to, but it's definitely a Pentile matrix...
Yes, definitely Pentile. Damn.
Well to me it looks ok and very much the same as mine. I have never returned my Desire to be fixed.
My colors are very vibrant and i can see the screen on daylight (using auto-brightness).
I have noticed one thing on your photos though: your Internet icon is different from mine. Yours seems an older icon, really washed out, being gray and having the home icon. Mine looks more recent, it's a earth icon in blue (same blue as the mail or message icons) with some orbits rotating around the world...
Could this be it?

The internet icon i think is Orange's reworking (notice the orange door to the house).
I just wanted to mention, I 've had 5x different Desires and some have had a more vibrant screen to others.
Through the range of brightness from minimal to maximum I've definitely been able to see that some of the handsets are bright but seem to have very slightly less clarity, whilst others have a sharper image but loose some vividness.
I prefer the brighter / more colourful one I have now.

5 Desires. I've been through 3 so far. The first two were very similar (although the second one for some reason just felt so much lighter). This one is washed out. Going to try and phone Orange and try and see if I can have another one sent. :/
Hi
I've bought yesterday my Desire and I've noticed that in the upper middle screen part there is a small yellowish backlight glow only seen on black background. Can You tell me if there should be one or I should take it back to the shop ? This is probably the new SLCD version. I don't know is this a flaw or all of the sceens have some little glow on the black.
Thanks in advance
yellowish backlight?
is it in a dot size?
have you try different background color (red, green, blue)?

It is some kind of LCD bleeding. It looks similar to the picture attached below.
Mine is just slightly visible compared to this photo (copied from androidforums.com) but still it's the same issue. I just wanted to confirm from a SLCD Desire user if this is a typical for those diplays, or if I should take it back to the shop.
Most LCD screens bleed light to some degree, but that looks totally unacceptable to me. I'd take it back.
EDIT: Oops, should have read the full post. Well that one above is really bad, any chance of getting a picture of yours?

Yeah, I finally managed to do some photos.
The second one is with other light source (a 20W lamp). The first and third are without any lamp, high iso photos, but the first one has added brigthness in Photoshop, and third is on default. Remember these photos are on full display brightness, just to show how the screen behaves on dark, black background.
cant u see if its slcd on the side of ur package?

It is a slcd because it doesn't say it's amoled on the back. I just wanted to know if all slcds in Desire have this problem. I don't want to take it back just to get another device that has the same problem or even worse.
Well that's definitely SLCD... OLED (like my phone) will be pitch black when it's on a black screen, as there is no backlight on them.
Yes that is definitely a flaw. I would definitely take it back. It's unlikely you'd get another one that bad.
I've found a film on YouTube:
So it's just probably the thing with all SLCD's. Still I love the phone and since I know that I won't get a AMOLED version I'll probably keep this and just have fun with it. Thank You all for Your replies
So I got my One X since thursday and noticed my screen has a "Yellow tint". I compared it with my Desire HD, which is more white..
Went to some shops to compare it.. one had about the same, and the other I compared with, had a noticeble difference, like on these pictures

Started a search at Google and found this post:
After all this trouble and bickering I finally have 2 Iphones side by side in the comfort of my home to compare.
1x 16gb Iphone 4 week 44 (Blue Tint) (My girlfriend)
1x 32gb Iphone 4 week 36 (Yellow Tint) (Mine)
Set both to max brightness:
Blue Tint:
- appears brighter
- more "White" when on the brightness screen settings
- when tilted to its side and there were no apparent "Light Bleed"
Yellow Tint:
- appears less bright
- less "White"
- when tilted LED backlit can be seen. However, only when looking at this extreme angle. Less extreme angle this is not an issue and should not be of a concern for both Screen Tints
Here's a thread describing what I mean by "tilted to side":
http://forums.macrumors.com/showthread.php?t=1030940
Here is what's really surprising
Colors:
Many look at the white screen and think the Blue Tint is a superior screen to the "Yellow Screen" but I exclusively own only IPS screens for my desktop, TV, and laptop and have compare many screens for color reproduction as well as the famous IPS viewing angles.
To do this comparison, the wallpaper settings was use for the many photos as well as Iphone dead pixel test for solid one color (black, red, blue, etc...). The lights was turned off so to get the full effects of the comparison.
Result:
Wow...the yellow screen reproduced color very accurate like an IPS screen should. Blacks look black, yellows are yellows, etc..., pictures are detailed and color accurate.
Blue Tint screen is a tiny bit of a disappointment. Colors look a little washed out. Blacks appear to have tint of gray. Color reproduction was off and not as accurate as the yellow screen. Only the blank white screen appears to be more vibrant but I suspect this is due to its unnatural color reproduction of "White".
Conclusion:
The "Yellow Tint" many of you have complained about (including myself) is not an issue but in actuality a blessing. The "Yellow Tint" has superior color reproduction...Whites, blacks, red, yellow, etc...you name it. However, on initial encounter the "Blue Tint" will appear whiter, brighter, and is reminiscent of TN screen technology and will offer an instant gratification that it is a superior screen but in fact the opposite. However, those who appreciate brightness more than color accuracy should be content with the "Blue Tint" while those who are more picture/graphical directed should opt for the "Yellow Tint". Either screen will be fine for Smart Phone operations but I prefer the "Yellow Tint" and my GF likes the "Whiter-Blue Tint"...Win Win.

Can someone confirm this quote? Is the "Yellow Tint" better?
Because I'm doubting about going to exchange my phone in the store
here is my feedback on this I spent time with both, both have their virtues, keep in mind out of box both will be extra yellower than usual due to lamination glue, needs few days to reach full brightness n colors
hamdir said:
yes the more i work the my One X, the more i realize things about the two screens
- Warm screen: Saturated colors, sharper contrast, less bright, more yellow/red whites, flawless color banding (display tester), no visible pixel grid, slightly better blacks. conclusion: richer like amoled
- Whiter screen: Accurate colors, less contrast, a lot more bright, colder whites, not as flawless color banding (display tester), very faint but visible pixel grid. conclusion: accurate like iphone
Both still the best screens i ever saw on a mobile device
here is my white screen from angle, you can see my semi dead pixel at the end of the word notifications, it only shows in angle and solid brightness, doesn't appear on black, its only annoying when im using the phone tilted like laid down on the table and im using whats app i can see it
absolutely no gap, flex or flicker so far
i also have the line in the polycarbonate shell like some reported, its in the lower left corner of the glossy side, perfectly straight seems part of the production process, the soft coated edge under the front screen is not as perfectly finished there is some noise in the coating and a tiny bump plus a pealed off edge, needs very close observation to see it
All not worth complaining about, i'm just showing you that even on the 9th One X i unboxed so far its still not a perfect specimen
by the way it mentions in the manual that the battery will stop charging if it gets hot as a precaution, same situation with iPad3

you can adjust your screen with this app; Screen Adjuster
Add for example, +12 to blue
But it makes your phone a little less smooth..
Well the HTC One X has a "Super IPS LCD2" screen whereas the iPhone 4 has a "LED-backlit IPS TFT", so while the yellow-tinted screen may be better on the iPhone, it might not necessarily be the same for the One X.

True, but I think it's similar to the One X, despite the screen difference.
What do you think is better? The "Yellow tint" or the "Blue tint" screen?
Does one of the phones run a custom rom on the pic of the two X's.
Or why is one bar green and the other blue on the brightness bar?

We need to get the 2 screens side by side really to fully test them out.

Both stock.. you can change your HTC theme, when you use the HTC aluminium skin, you'll get blue instead of green

on the picture it shows 2 next to each other, both stock
also, I went to the city yesterday, to check with some demo models
1 got the "yellow tint" and the other one got the "blue tint, more white"
Comparing the output of the "yellow" screen with my calibrated monitor, I don't think it is over-saturated. It looks pretty "bang-on" in that aspect and one of the best phone screens I have seen in that regard. So if the "white" screen is less saturated, it is probably that one that is more wrong in that regard.
Saying that, I don't really care how accurate a phone screen is as long as it looks pleasing to the eye. In that regard, I would probably prefer the whiter one.
Often the reason for colour temperature choices of backlight is to do with the saturation.
One of my 6 HTC One Xs had the whiter screen and it was immediately apparent that it was different. It also had different viewing angles to the yellowy one. However, it was also clear that while it was brighter, that black level was not as good either.
Neither screen is perfect....and trying to find the whiter one is like a lottery because there are clearly less of those in circulation so far.
After quite a number of years we are still scrapping around to get screens with good backlights, good colour temperature, good uniformity, no bleed, no stuck/dead pixels. Technology has not moved as fast as I would have hoped.
I think the biggest issue is not which screen is the best, but that the consumer doesn't know what he's going to get. That's really bad and unacceptable. The difference is too big to be a normal situation.
Ok, than I just keep the one I got now
i know the warm one might look less appealing to the eye, since colder tint is always more eye pleasing but the warm one has a lot going on for it
better blacks and hence better contrast, flawless in banding test and most importantly no visible pixel grid (the scan-line like grid on the white version)
both are amazing, much better contrasts than the iPhone4 Retina display and iPad3
and i really think we are starting to get spoiled if we exchange for this reason

Gah, sorry, the pictures didn't show up for me when I posted ><
The "blue tint" looks a lot better in my opinion, I realise the "yellow tint" one may technically be better, but the "blue tint" is much easier on the eye.
I've got a blue tint display on my One X and I've had some yellow tint display devices (not One X, but some "old" Motos with LCD and some other HTCs with LCD).
I've always hated the yellow tint and I find the blue one is better.
Also, I've tried to get a blue tint using screen adjuster softwares on my yellow tint displays, without any particular success....while on blue tint displays I've been able to get yellow tint just fine.
Personally, I think blueish ones are better.
Have any of you complaining (op not intended) actually compared the two screens on THIS phone. I did a little test in the store and can confirm what has been said here about warmer tinted ips screens. The yellow one, on this phone, is amazing the contrast is deep, colors jump from the screen and I found that even the viewing angle was far superior to the colder tinted screen. I specifically bought the warmer tinted screen as, apart from displaying an entirely white screen, I and the store employees all found it to be much much better, very close to amoled.

Most people arn't returning their phones because yellow screen is not a issue for them. Interesting

I can confirm this except the view angles which get darker on the yellow screen
depth and contrast for sure like amoled, also it has a significant advantage if you look close the screen doesn't not show any pattern, while the whiter acer screen has a horizontal lines grid
people who updated to 1.29 are saying it cures the extra yellow if that is the case on the yellow screen, it becomes the winner in my eye
I really hate the grid on the acer screen it reduces pixel density, it's very faint but its there
I would definitely change back to the yellow/sharp if I get the change, its more impressive overall and calibration can always be fixed either by an HTC update or dev efforts
Never noticed a yellow tint on my phones original screen. When I got it back from repair it now has a yellow tint. Definately noticable to acceptable to me
If you have this issue, just call HTC and tell them about your situation, they will normally replace it with a new one.
