[Q] How do I fix stuck pixels on my IPS display? - General Questions and Answers

Hello!
Please help me to fix two (maybe there are more, I haven't noticed yet; but I hope there aren't any more) stuck pixels on my Cynus T1's IPS display. One pixel is somewhere at the top of the screen and is blue when the screen is black and... is dark when the screen is blue. Another one is always white and located somewhere on the right side.
I tried to fix these pixels by running JScreenFix with maximal brightness. Overall this app has worked for... errr.. 3 hours with regular pauses when I wanted to know whether these pixels have been already fixed.
So JScreenFix did'nt help. Maybe run it for more than 3 hours? BTW can other pixels get stuck because of this app running and display working for a long time.
Another idea I have read in one forum is to... freeze the phone in a refrigerator (previously putting out acc, cards and sim). It is claimed by some people that this method will help to free stuck pixels.
To say more, currently my phone is in a refrigerator. I hope this won't at least damage more pixels... Or should I run and get it out of there??
So, what can you suggest?? I repeat: screen is IPS type....

[Q][Xoom 2] Dead pixel

Hi,
I just bought new Xoom 2 and I have 1 dead pixel. Is it enough to put the tablet on warranty repair?
You have to check with your warranty papers.
From what I know, you need a percentage of pixels to be dead in order to issue a refund/replace.
Something like 7-8% .
Just like monitors & tv sets.
That would be entirely too high of a percentage. Usually it's like 3 or more dead pixels, or 2 connected. Are you sure they are dead though? If they are just stuck (dead pixels are black, stuck pixels stay red, green, etc), then you should be able to just find a flash .GIF file or even an app that flashes all the colors to get it fixed.
This must be a stuck pixel, is only visible when screen is black or very dark. Am I able to repair it just flashing this place with gif image?
edit: now I have 6 stuck pixels, the rest are smaller, I probably didnt see them :[
Return it to where you purchased it or send it in, that's unacceptable. While you're at it...just take back the Xoom 2 and get a Xoom.

Can software really fix a stuck pixel?

I just got a replacement Nexus 5 which is fine except for 1 stuck green pixel just about at the centre of the screen. It's a bit annoying. I don't know if they would send me a new phone over this or if it's worth the hassle.
There are a number of apps that claim to fix stuck pixels by cycling through colours. I've tried a few for a few minutes. People in the comments have said running it overnight fixed their stuck pixels.
Does this really work? What's the principle that would allow a stuck pixel to become unstuck?
If I want to try this should the screen be set to maximum brightness or not? I'm a little concerned that leaving the phone plugged in with the screen on at max brightness may cause damage to the phone or screen due to overheating. Is this something I should be worried about?
Thanks.

Usualy its hardware (screen itself) related so software cannot fix that.
No. In answer to your question

So what's going on with people who claim it's worked for them?
In any case, I think I'll call Google and see if I can get another replacement. Maybe third time will be the charm...
Because it can work.
Think of each pixel as 3 switches.
One red. One blue. B one green.
In your case one pixel has the green switch stuck on.
These apps are designed to force the switches to keep turning on and off.
Sometimes you can get lucky and the switch will eventually free itself after so many tries.
Sometimes it will not work no matter what.
These apps just try to get it unstuck.
Sometimes it works. Sometimes it doesn't

[Q] Defective display?

I don't really know what is happening but my year old nexus 5 seems to be developing a display problem.
It got a yellowish tint at the bottom of the screen but the top 3/4 is totally fine. What is causing it and is it just me who have this problem? Also, if you have any, please post some solutions to the problem without RMA or replacing anything.
It might be something about light leak but I am not seeing any when the screen is displaying a black picture.

I have a similar thing but it tends to only be on the bottom 1/8 of the screen.
I tend to find this is because this is the least used area of the screen - being where the soft keys go. Try running it full screen, full brightness on a white page (probably using something like this https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&hl=en_GB). When you do this, does the yellowish tint fade over time?

By Over Time do you mean 30 minutes or a day? I tried this method before for about half an hour and it does not seems to be working. Will try it again now. But will it really help?
My OCD is killing me. I told myself not to look at the tint and I end up just staring at it.

G920T Screen burning or whatever its called

Hey guys, I recently got this problem of my OLED screen getting burn in effect or whatever this thing is called. Anyways, everytime I lock my phone and unlock it acts up and goes away after 10-30 secs. I will upload a picture and maybe someone can help me and tell me what the problem might be.
*P.S: it started acting up 2 days ago and today the screen was black with these lines on the bottom. I haven't dropped it either.

that is not a screen burn in, looks more like a faulty display. try claiming your warranty
I had that sort of problem with an incompatible kernel on my rom. Try another rom or update to latest official stock firmware
Looks like resolution is not set to WQHD, check to see if it's incorrectly set to FHD.
I fixed it. Thank you guys.
LoL its not a screen burn !!
Screen Burn Means the pixels of ur display go completely black
U hv switched to HD/FHD resolution which aint supported by current ROM so change resolution to WQHD

Lol no, screen burn-in means the image who was showed too much time has marked screen pixels.

X2 Pro Screen burn?

I'm using CN X2 Pro, 2 weeks old. I noticed that I get 1-2 seconds of ghosting/screen burn from the always on display when I unlock the phone. I still see the dark numbers on my light background. This fades after 1-2 seconds but I've never noticed this on other phones with AoD's? Do you think it's a sign my display might suffer in the future?
I have the same issue with AOD turn on, there is a ghost effect and disappear after few second. I found if you choose dimmer clock color, there is no issue. So, try switch to different clock style, try avoid those white color clock.
Hi. I have the same problem. What do you do guys? Other light spot and the same trouble
Hello. I think its's because of AMOLED screen.
I started getting it with AOD after updating to Android/ColorOS 11.
Previously, the AOD would move around the screen so it didn't happen.
I've had to turn off AOD because of this.
And what do you do? Send to service or something?

Interesting. Yes, prolonged static displays should be avoided.
AMOLED screens do not suffer from burn in. They degrade over time from usage.
They have a long but finite life span.
High screen intensity is the biggest degradation accelerant plus time. High heat ie sunlight should be avoided when possible.
The highest energy blue pixels burn out first, lowest energy red pixels last.
Damage shouldn't be observable in a screen so new. These screens are rated for thousands of hours.
The ghosting may be a firmware glitch and nothing more.
Avoid using over 50% intensity except when needed.
Don't use in direct sunlight except briefly.
Make use of black wallpapers and dark mode as much as possible. Whites and blues should cause the most damage. Reds the least.

So what do you suggest? Warranty, hard reset or just learn to live with it. can update help you think?

A hard reset will do nothing but waste your time and patience.
If you really have damaged pixels, warranty as the display is likely defective.
If it's not actual physical damage only a firmware update can fix it. It may take months or never come at all. So again, I send it back either to be fixed, replaced with a new unit or a 100% cash refund. Nothing less.
Use screen testing app like this one:
Display Tester – Apps on Google Play
Test your screen and figure out whether it has hassles.
play.google.com
I use Screen Test but can't pull up a link. Playstore may have pulled it... as usual.
I guess I will only send the problem is that I bought it abroad and it will probably take two months

That sucks. If the problem is physical it may degrade rapidly; a new display shouldn't have these symptoms.

if there is a bright point, you can see it for about 5 seconds on a gray background. the brighter the screen is, the clearer it is. after a while it disappears

Sounds like hardware. Either way unacceptable.
