Visible dots grid in the screen when turned on (touch sensors) - Touch HD General

Hi,
I wonder if anyone else has noticed this in the blackstone; I can see a grid of dots all over the screen when it's turned on. Ok, you have to look closely, but it's a bit annoying. I can see the dots better when I have a white or green background. For example, going to Start -> Programs I see the dots in the space between the icons.
I know the dots are from the 'resistive' layer, the dots are the sensors of the touchscreen... but they become visible and appear as small green dots perfectly aligned. I don't see them all the time, only when I have a white background or looking with a certain angle.
Should I be concerned? Could it be a problem with my screen?
Thanks!

Sounds a bit strange to me, the only time I can see the dots/grid is in bright sunlight. Then they look like small pin points in plastic.

i've never noticed that on mine...

That is normal, those are touch sensors for the screen. They allow the screen to recognise a touch.

Agree, but I had other PDAs before and never seen the dots when the screen is turned on. I don't care about the dots being visible when I'm under a bright light; my point is that I can see the dots when the screen is turned on, no matter under what kind of light. When I have a white backround, it looks like there's dust on the screen. If I look closely, I can see the dots in green colour, as a result of the reflectied light from the screen. I know they are the touch sensors, but it seems no one else can see them--
Any idea?
Thanks!

it is indeed normal especially under bright sunlight. However if you insist that you can see them when you switvh your device on, no matter the external light conditions, there might be something wrong with the screen. Have you seen other HD phones recently? Do you see the same dots there when they're switched on?

I haven't had the chance to see another HD; I've looked at a Diamond and Cruise, the dots are NOT there. I've tried to take a picture, but seems impossible to see the points in a picture (at least for the N95's camera).
I found an old tread talking about old PDAs that had the same issue, maybe they explain the issue better: http://forum.brighthand.com/showthread.php?t=207321
I'm not sure if I should send the HD to the service. Anyone knows how the 'worlwide warranty' works? I sent an email using htc.com site, but they don't respond.
Thanks!

Any advice on this matter...?

I don't know about colored dots, but every pocket pc I've ever owned had the dot grid visible in sunlight, it is normal, they should be clear dots though.

samsung vibrant pixel marks

There seems to be an issue with the super amoled screen. Its not a biggy as of yet. It seems if you have something on the screen for long periods of time it will wear the pixels out. My example....if you go on a white screen in landscape, the look where the status bar usually is (where it says samssamsun) you can see a fainted image of the status bar and a collage of times, battery and signal (i assume from always changing). U cant really see it and sometimes i wish i couldnt. Small flaws like this upset me. My phone isnt rooted (no screen shots) if you have a vibrant or galaxy s. Could you text and see if this is a product wide issue. Thank you for reading please leave comments.
Don't see that on my phone?
uhh, a screen shot wouldnt show burned out or worn out pixels dude.
So I ran the flashlight application, held up the screen, tried looking at different angles, and couldn't find one anomaly.
You should trade it in for a new one.
did the same thing with the flashlight app, nothing shows up. this dude is on crack.

Maybe he just has a lemon?
I can attest to this. I see it after just booting up and going from the lock screen to the desktop. I can see the faint outline of the white numbers from the time on the lockscreen on my GenieWidget on my desktop at the top of my homescreen(widget has grey background). It seems to dissappear though.
I have some when using color flashlight I see marks where the time is. It is very light but I see it. Tmobile is replacing it now. Lol

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.

Matrix of Dots on the Screen

Hi Everybody,
I got the HTC Desire HD from a time, just i am asking about something
There is a matrix of dots which is visible under the screen in certain light conditions (when the Screen is off), I know this is the Multitouch Matrix and this is normal
but i have other Grid of Dots on the surface of the screen itself, you can see it when you illuminate the screen and there is a white background for example or any solid color, is this considered normal
what is this other Matrix
Note : this one appears on the surface of the Glass of the Screen, I also noticed it on HTC HD7 but it was very strong than the Desire HD Case
What is this Matrix
Thanks
If I'm honest I think it's the exact same matrix of dots...
If I close either my left or right eye, I can't see it any more, but when they're both open I can see it, though it flickers between alternate dots.
If I then tilt the screen then some appear and some disappear. i think it's just the white background playing tricks with the eyes. They appear red to me also...
I think it's the same one, just looking a bit weird because of the backlight...
There are two layers/arrangements of dots. A grid of dots about 1mm apart and a grid of dots about 5mm apart.
you should see the matrix/diagonal lines on the screen of the Archos 101! very visible at any angle when screen is off

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.

Oled problem?

Hi, I moved from OG pixel to pixel 4 and noticed that screen has problem. On 100% on brightness when opening totally black picture screen is not totally turned off and when touching it screen greys out a bit. Is it bug or hardware issue?
Can anyone check it on own device?

I have noticed the following: When screen brightness is 50% or less and I touch the screen such as typing on keyboard, the screen flashes very slightly on every tap. It feels like the screen draws too much power and battery is low. I went to Verizon store to check display unit and it did the same thing. Maybe your issue is similar

I didn't contact Google because the store model had the same thing. I just tried to troubleshoot what could be causing it and seems that when I disable "smooth display" in settings>display and then tried to reproduce the issue by typing on the keyboard and the screen doesn't seem to flicker anymore.
Try to disable the setting on your phone and see. This might be a software issue then.
I found similar thread(you are probably on it too) on Google community site and replied to that thread: https://support.google.com/pixelphone/thread/22331033?hl=en

You are right I disabled smooth display and it stopped flickering but there is one more thing when brightness is on 100% and opening totally black picture I can notice little lightning of the screen in corners it means that pixels are not going off like it should be on oled screens. Could you please check it also?
It could be checked only in the dark daytime it's not noticable

Alright, I found a black image with only a small moon in the middle. Did the test on 100% full brightness but don't see any pixels on the screen. Check my image(attached) and compare.

Yes, of course. I turned off the lights. I have seen issues where some phones had some light seeping through(light bleed) at some edges. Is that what you see?

It is difficult to understand anything from the picture. Try some display test apps. Check to see if you have something installed such as 3rd party theme or an app that interferes with the display of your phone. Also if you can compare your phone with the one from the store.

If it is in the corner(s) then it is light bleed. The screen is good and it is just some screen backlight being seen through the frame. At least this is how I understand your situation from my previous experience.

So can you notice such light bleed on your pixel? or it's on my pixel only?
