colourful mark at the center of the screen

Hi all,
Just noticed this issue and want to see if there are any others noticed the same before or can check their HD2 for same issue.
My HD2 screen is perfect under day light or yellow light at night. with no mark-spot and very smooth.
Bu last night I noticed that under white light like fluorescent, there is a mark at the center of the screen with colours. you can see it when the screen is on or off. But on daylight or yellow light lamp, you can not see it in anyway.
Can you please check yours in white light?
Thanks.

reminder please

Could be a light case of newton ring...
I sat on my HD2 and ended up with what looked like a smudge / spot on my screen which had a kind of petrol rainbow around it...(you know when petrol mixes with water on the ground you can see a kind of rainbow effect??).
It was the "newton ring" issue, HTC replaced the screen for me via the service center...(search for "newton ring" on this forum and you can see many posts / pics I think)
What you have could be a light form of that, I guess the "smudge" (which was pretty prominent on my phone) is small on yours and you can only see the rainbow colours that appear around it...
On my phone the smudge and colors were right in the center of the screen...
Hope this helps.
Whatever

It is good to hear a reply. very clear.
Thank you.

thank you very much.
please try in LCD Test(*#0*# in Diagnostic Mode) select RED you will see a white border but on my device left-border is green (other sides are OK).

It's very hard to be absolutely sure on red, but on blue and green the edges are definitely all white.

I loaded your JPG onto my Focus and the left side is green. The left side is always green, but the right side and even the top and bottom can also appear green if you hold the phone at certain angles. The green can also appear purple at extreme angles.
Is this a manufacturing flaw, or just a characteristic of AMOLED screens? Could it be some sort of back-lighting source that's located along the left edge that's causing the green tint?

I loaded the picture after downloading it and then attaching it to an email.
It does have a strange tint on the left side.
I then created my own version of the image. I started with a 480 x 800 blank image in Photoshop. I filled the entire image with black at 100% opaque.
Then I stroked the outer edge with 1 pixel of white. I repeated this using 2 pixels and then 3 pixels. As you can see, it is still visible at 3 pixels, but it is starting to turn white. I think we are seeing a consistent result that means the AMOLED screens have a slight design problem that is not considered to be worth holding back this technology from the market. I know I like the display and this is minor.

darker and brighter stripes on gray background

i have this problem(maybe common in amoled devices) if i take gray pitchure and put it on background there is distorsion in grey. like brighter and darker stripes(but you need to look it realy good) for exsample download program screen helper lite and tell me do you see stripes on main gray program screen.

There is a thread going for so long,

I think that he meant this:

I dont think he is refering to both yellowish screens or banding.
I'm having this issue too. It doesnt show itself unless the screen brightness is turned down, and especially an grey background. There will be faint large vertical stripes. It is as if the backlighting is uneven. Increase the brightness and it'll go away.
Seeing that i do not have the yellowish screen problem, no stuck/dead pixels and no bluish tint problem, im very reluctant to send this phone back for a replacement due to this problem. Its something that i can live with.

Problem with screen backlight

Hello,
When I checked my phone today, I noticed that on left and right side of the screen, backlight seems to be different than on the rest. This causes screen to have different colour on the borders, like a little bit brighter. Is this a common problem? Anybody else had this issue? Any way to fix this, or should I replace the whole panel?

Mine has screen bleed as well. And every P8 that i saw had an amount of light bleed. So the chance to get a new screen with same screen bleed is high..

Mine has a little in the bottom left corner, unnoticable though unless I install the Backlight Bleed Test app & run it.
I was going to ask you to post a screenshot to see how much BLB there is on yours (would've posted mine too), but it doesn't show up in screenshots.
