Thought I would make a separate thread for this.
I have 2 HTC One X in my possession, one with a great display but has every glitch you could moan about, and my second one seemed perfect only it has a Yellow tinted screen. But today when I was Booting up the Yellow screen One X, I saw that the colours change and the screen goes more yellow after a second, once powered up. The screen is still yellowish to boot before that, but much whiter than when it does boot. Why on earth is this happening? Is it loading a bad colour profile? Are the lights behind the screen yellow? Can anyone else with a Yellow screen confirm this? Can you see a colour change when booting up?
I tested my glitchy One X, and it does the same flicker at boot, but doesn't change the colours. This phone is so bad... I'm sending them back for a refund now. This is really the last straw. Wish there was an app to change the lighting behind the screen of phones...

I have the same problem. My screen has a yellow tint, and when I boot it up it's not yellow the first 2 seconds but then ik flickers and i becomens yellow.
My screen is very warm (reddish hue), but the whites are clear without any yellowing.
Can you please check if the Mirror app makes you look very red/pink? I've been begging users on another thread to check but no one replied to me. Thanks.
Yes, I look quite red on the front facing camera too. In daylight it looks much better.,

I've found out, that the Amoled can't display perfect black. I tried the desktop clock thing, the blackle Google page (scrolled to black only area), and I made a photo in PhotoShop completely black and open it up in gallery.
What I noticed is, that the screen still is displaying something when it should be black. This is very easy to see if you put the phone to sleep when displaying such black.
What am I missing? Doesn't the Amoled completely turn of a pixel that is black? Can someone try to replicate this?
Do you think it's possible that I have an lcd desire and just don't know it?

I have also a Hero (with lcd display) and black on my Desire is "more black" than Hero's
For me it's ok
If you look at LCD screens through a circular polarisation filter you'll sometimes see coloured patterns on it, or it will get completely filtered out at a certain angle. To the best of my knowledge, OLEDs don't emit polarised light, so if you've been to see Avatar or another movie in Real3D and walked away with the glasses then you can use them as an LCD detector...
(The blacking out effect works as a cool CSI-esque monitor dust detector)
No disrespect, but... who cares???
So the blacks are not as deep as say, a Kuro plasma. This is a smartphone, not a home theater tv.

well real black "off pixel" don't use power so all the people who care about batterylife might care...

I don't think they do emit light on blacks. I have noticed that in a completely dark room I can't see blacks on my Desire at all, it emits no visual light. Maybe the black you were testing isn't pure black.

"It's like, how much more black could this be? And the answer is none. None more black."
Couldn't help myself

I do agree that it is much better than any lcd. BUT black should be no light at all. When you turn off the screen when all the pixels are supposed to be off, you see a change. You can also see the outline of the screen when it is in any of the previously mentioned methods of darkness.

I did the following test :
- found a room where I could be in complete darkness
- used the following enclosed file (a pure RGB=(0,0,0) 800x480 png file) and displayed it fullscreen on my phone.
- use the palm of a hand to cover the 4 lit buttons
- the screen is pretty damn BLACK ! (an LCD screen, next to it, also displaying black pixels, would look like a torchlight)
- After a minute or so, the eyes getting used to the darkness, I could very slightly see the screen. I don't know how the phone is built, but I'm guessing it's a light "leak" coming from the LED(s) of the 4 buttons.
I tried this procedure at various brightness settings (from min to max) : the remaining light coming from the screen did not change.
Is there a mod to kill the buttons backlight ?
It is possible to kill the backlights, but have not tried it myself.

Ok, switched off the buttons backlight thx to Flaggie. The screen indeed still emits some light when displaying a full screen black picture. Strange.
It would be interesting to get an explanation from HTC about this, but i'm pretty sure it pointless hoping they would reply to such a question. I'll give it a try...
Perhaps you hae one of those new Desire models with a LCD screen?
No, I bought it the day it came out. Try out on your own. The test I detailed is pretty straight forward...

That is what I thought at first, but than the amount of light on dark would change when you change the brightness.
I want to know what HTC has to say about this.
PS: I bought my phone in June.

OMG does any of you know how a led screen works? lol Active Matrix Organic Light Emitting Diode its name clearly states that the pixels are self-illuminating so clearly unless the screen is of the display is always going to give some light off
It is actually the other way around. They are self emitting, they can turn off. LCDs, however have a backlight, which doesn't turn off, so some light still passes through.

OLED can havae infinate contrast ratios. I have a cowon s9, it has an OLED screen and in a pitch black room you cannot tell it's on. The desire does emit some light even on true black :-/

Unlike over saturated colors and Pentile jagginess which are clearly visible and to some point distracting (at least to me) this seem like pure academic issue, since it can be visible only in total darkness and even then it is not visible unless screen is completely black.
What would be practical purpose in looking at black screen in darkness?

I agree. This is an academic issue, but aren't you a bit disturbed by the fact that there has been soo much talk about this oled screen and its pure black, and it was all a lie?
I think the problem might be in the image to screen processing where it gets converted to the pentile matrix(and over saturated).

Hey guy,
So a friend of mine had a strange problem with his htc desire
Last night while reading some stuff his displayed color changed,
first thing i noticed was the rly pinkish tint, everything was slightly pink Oo
noticed this Thread but that wasnt the issue here
hope u guys can see sth, it seems its only 8bit color depth, 256 color
since some pictures are getting some rly ugly "blocks" in it
Well my question is, is the display broken? should he get a new one?
can a new rom fix this problem?
Thanks in advance
Kemo~
Try resetting brightness to auto.
we did that already, the pink tint increases with lower brightness
we also did a hardreset of the phone nothing changed
When i take a picture with ddms.bat it looks normal
its rly strange :/
Is it an LCD (slcd) or AMOLED Desire?
Its an amoled
Sent from my HTC Desire using XDA App
The AMOLED screen on the Desire has more red pixels (not quite right, but the easiest way to put it) then blue or green. What this means, is that the screen of the Desire is inherently tinted red. This is mainly more noticeable when the brightness is at low level as the color spectrum on a screen uses light to adjust the colors. With less light, the red has more of a bleed through effect and becomes noticeable. I really don't notice it unless it is at VERY low light or I have the screen with a white background and next to a device with another high end type of display such as the iPhone 4 or the Galaxy S which don't have the bleed through effect... well, with red anyways... they have the effect with blue.
Strange... I've seen oled displays look like that after only a year but that's in very rare cases. They wear out but not just like that if it happened almost insantly.
Did you look at the display just when it happened, did the other colors just sort of fade away or did they go in a snap?
it happend in an instant, an no i didnt have a look at it when it happend
but it seems the display is broken
well he gonna replace it, lucky he still has warranty =)
Thanks guys for the replies
Cheers

Hi,
I got a grey One X last week and while fairly happy with the phone I thought the notification LED was pretty dim. Unless I look at the phone flat on I can't see it is on. I accepted this was to do with the LED being placed within the speaker grill; however a friend got a White version a few days later and the LED on his is about 3 times brighter.
A few videos I have seen show the Grey phone has a very dim light, would post them but can't link unfortunately.

Has anyone else noticed this or is this an issue with my phone?

I think that is simply because with the white casing, the light is able to shine through the white casing itself. Whereas obviously with the darker casing, it is truly confined to the tiny little hole of the earpiece. I do get the feeling that HTC designed the white one first
Yeah maybe, but comparing the two side by side, it looks as though his LED is a different type entirely. Looking at the LED straight on should negate the case colour and in that scenario his white version is still far brighter.
As long as other people think the grey one is dim there is no reason to send mine back.

It was one of the first things I noticed when I held a grey one. So I don't think it is faulty. But just like most things, LEDs do vary from unit to unit in brightness.
i haven't seen a grey one, but with my 2nd white replacement, the charging led was stupidly dim. now im on the 3rd replacement, the same led is much much brighter. leads me to believe it was positioned incorrectly, or just a crap led.
quality control really sucks atm.
Ever since I got my Xperia M the display has had blueish tint and bad color reproduction but I acknowledged that is a problem with every Xperia M. But beside that, when I look at the display from an angle, on a white background, I can see a gray line appearing from top of the screen and a gray circle in the middle. Again, it is visible as an effect when looking at an angle, cannot see it when looking directly at it. I also have a bright pixel on a black background. Are these also negligible, common issues or along already bad screen I've got a defected screen? I am very disappointed in Sony anyhow.

I'm pretty sure I saw this post somewhere b4... anyway for bluish tint - get the white balance app from @xperiaz2 (Yes, you need root and the bluish tint is due to the colour temperature, its at around 10k+, the norm. being around 6500k) Gray line appearing... pretty sure you're having a defected display and about the bright pixel, display is defected. Yes you got a defected screen (The bluish tint is not a defect though) so just bring it back to where you bought it and they'll replace it for you! (If the warranty is still live)
Well I posted on Xperia support forum trying to get help there, too. Or just an insight of what could that be and what could cause the problem. Anyway, here are a couple of pictures taken with a phone. The camera couldn't get that grey line properly but it appeared as a shadow from the top of the screen probably because as I said it's like an effect when tilting the phone, not a still colour. http://imgur.com/3Ae2rdr http://imgur.com/Nyv2maS
I suggest you to bring it back to the shop, that problem isn't present on mine.
So I just bought a cheap used tab S 10.5, and though it is in otherwise perfect condition it seems that it was some sort of display model at some point, because against a blue or white background there is some visible burn in of some text that is obviously from a samsung promo video.
Thing is, the "burned in" part is actually brighter than the rest of the screen, not darker, and the video that i believe was playing on this screen for a long time has black text over a white background. Here's a pic of what seems to be the same video that was running on mine: i.imgur.com/drGA93d.png
So the conclusion i've come to is that the whole screen is worn in except for where that text was shown. Is it a good solution to just leave the screen on with a fully white screen and high brightness to try to wear down those bright pixels to the same level as the rest of the screen? would it be better to maybe do that with only that specific section of the screen lit up instead?
Here is an link to the Same image that burned you tablet, you might be invert it so the black becomes white and you can avarge the burn across your whole tablet screen.
Also i inverted the image for you, make sure the image lines up perfectly with the burn-in on you screen then stop the screen from turning off, and run the brightness at max or whatever you are same with, I accept no responsibility for any damage that happens.

John.
I don't think that's going to work. The display is amoled not LCD. The dark parts will simply be in an off state, so will have no effect.
Only the active pixels in the middle are going to be on, which may further increase the burn in effect.
^thats the main idea, if you read the post again, it was a black text over a white background. I.verting the color and burning in the white text over a black background may help lessen the degration between the burned in parts

Although this may not be exactly what you're looking for it may help in fine tuning your screen colors to lessen the burn-in effect. It is a new SAMOLED color control but needs root which is possible without tripping KNOX (keep waranty). The devs are looking for beta testers.
