Screen Burn

[Guest surgex]

So I opened up a browser yesterday and navigated to a page that was mostly white and I could see the after-image of the lock screen burned into my display.

I have it set to not turn the screen off when it's plugged in, but I usually make sure that when I plug it in I manually lock the phone and turn the screen off.

Well, I didn't realize until today that it will turn the screen back on by itself when it's done charging (why!?) and will keep it on.

Just a warning I guess...I think I am pretty much screwed, I don't think Verizon will give me another one.

Sucks, I just got this phone in December.

Really suprising how short of a time span it took for the screen to get a "burn" in image though..is this normal?

I've never had a phone do this to me before, and I've had tons of devices.

I am open to suggestions if anyone has a possible fix for this but I doubt there is one, aside from replacing the screen.

I've googled this and some people seem to think OLED \ AMOLED screen burn in is "impossible" and others say they are *more* succeptible to it.

Anyone have any ideas or say on the subject?

use the warranty that your phone has...1 year............

If this is similar to what I see on my screen, then the image didn't burn in on yours, but rather, the blue sub-pixels simply burnt out.

Blue AMOLED sub-pixels generally die out fast, and they are always "on" when you have anything white on the screen. So when you have a few blue sub-pixels die out and you try to load up an all white wallpaper or image, the parts with dead (or halfway dead) blue sub-pixels seem to show reddish-green burn in images. I think this is exactly the reason why Samsung's themes are mostly black, to try to prolong the sub-pixels in each pixel. I'm actually going to drop by the service center a month before my warranty is over to make sure they get the LCD replaced for free before the phone goes out of warranty.

Yes AMOLED displays do have a limited lifetime (as do LCD and LED displays) but this would typically be longer than the usual lifespan of the whole phone. Below is a quote from Wikipedia about AMOLED lifespan (that doesn't mean it's true but it is consistent with what I have read elsewhere).

"The biggest technical problem for OLEDs is the limited lifetime of the organic materials. In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays, which is lower than the typical lifetime of LCD, LED or PDP technology—each currently rated for about 60,000 hours to half brightness, depending on manufacturer and model. However, some manufacturers displays aim to increase the lifespan of OLED displays, pushing their expected life past that of LCD displays by improving light outcoupling, thus achieving the same brightness at a lower drive current. In 2007, experimental OLEDs were created which can sustain 400 cd/m2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs."

Thanks for the info.

I'm gonna see if i can get a new phone from Verizon tommorrow.

Wish me luck :P

Good info

Cutting back on my white based themes that I use :P

:( :(

[Guest CosminV]

maby that's why samsung insists in using black themes for the display...

[Guest jbr05ki]

It saves battery as well.

Black theme because AMOLED screen would automatically switches off the LEDS when it is displaying black, thus it would produce a beautiful pure black image, rather than LCD screens which is more to the grey side for their black colour.

[Guest CosminV]

i know, i was just joking...

[Guest dwallersv]

This would suggest that not only white should be avoided, but even more any theme that has an overall blue average to it (for example, on MS3 I'm using a Lifestyle background of a seascape with blue sky -- lots of blue tones everywhere... that's gone!). Especially for lockscreen images, or anything that might inadvertantly sit there on the screen for hours, accidentally or otherwise.

So, in that vein, here's some help. Below is a Hue color wheel I've modified to show the range of colors that keep blue in an RGB triplet to half power or less. Stick with scenes that are heavy on the coloration on the light half of the wheel (between 330 and 150 degrees, clockwise), and you'll be giving your blue subpixels a lot less of a workout.

Yes, this sucks, but I'm not posting here to share in a bitch and moan session, so please save that for somewhere else. The display is what it is, I don't think there's any reason to take any precautions for active viewing of images and video, however it's probably a good idea to be aware of this problem for anything like backgrounds that may sit there displaying while you're not around.

If you have photoshop, you can do a histogram on any image and get a clear, detailed picture of the color distribution, making it very easy to select images that stay away from strong blues. Generally, desert images, sunsets, forests, some tropical stuff (where there's not a lot of sky), people (of course, this depends on what they're wearing), cityscapes, etc. -- all are usually pretty low on blue.

The worst are images with lots of clear sky, or ocean.

In my case taskbar is burnt into the screen. Barely visible on red screen, but easy to see on green and blue.

Crap... that's a shame.

One of the reasons I went to Tacchan's dusk taskbar (green version).

[Guest surgex]

Mother f-----...

I went into the power options and changed the settings to this:

Battery:

Turn on backlight when screen is tapped or when button is pressed [yes]

Turn off backlight when not used for [60 seconds]

Turn off device when not used for [2 min]

External Power:

Turn on backlight when screen is tapped or when button is pressed [yes]

Turn on backlight when screen is tapped or when button is pressed [yes]

Turn off backlight when not used for [60 seconds]

Turn off device when not used for [5 min]

However, if I have it plugged in and charging, when it's charged to 100% the screen comes back on and doesn't turn off and it stays on the lock screen (the exact issue that caused the screen burn to happen) -- GRRR SAMSUNG!!!!!!!!!

Is there any way to shut this off?

Also very annoying is that stupid notification box that just won't go away until you unplug the phone after it charges to 100%..

Can we disable this somehow?

This whole "green" thing has really gotten out of hand...

EDIT:

I soft reset and it looks like this is fixed, the screen turns off now.

Would still like to get rid of that notification though ;)

I noticed I have some screen burn too. Oh well.

[Guest babyjosef17]

I use this as my Dummy Lockscreen. With this left ON, will cause my pixels to die?

Its all black execpt for the logo in the middle.

[Guest jlccarv]

interesting info.. ive always used black themes, mainly because i like how they look and because of the slight decrease in power usage. this is another reason i guess...

[Guest BLEK0TA]

can you post photo image of that screen burned on the amoled display? cuz TV seller said me yesterday it is not possible cuz amoled on mobile device is too low power pixel supply for burning it on screen

so he is proffesional and said: it is HOAX

Then your TV seller is not so professional.

Unfortunately blue pixels can "burn-in". You can see it yourself: under Windows click file named LCDTest.exe and then window labeled "blue". Now whole screen is lighted with blue pixels only. Watch closely, especially upper side of the screen where usualy are "battery" or "speaker" icons.

My O2 is only 4 months old but burn-in is very clear.

[Guest dsa88]

i've got burn-in the taskbar on my wm65 O2, the whole upper line usually filled with white icons

tried jscreenfix but:

1) theres no WVGA, WM65, O2 support

2) java MIDlet are not fullscreen, dummies left the taskbar above the shuffling screen

3) i dont know how to run javascrip jnlp file

4) jscreenfix videos wont run

http://www.jscreenfix.com/faq/17-how-do-i-...screenfixmidlet

any idea how to run MIDlet in real full screen or any other alternative for this problem?

tnx

[Guest thebass]

I'm right there with you guys, I had my taskbar burn in and I was really shocked since I turn off my screen every time I quickly use it. It happens when I'm sleeping and the battery gets fully charged and the screen just happily burns its life away. Now I have huge titties burned into the middle of my screen. What do I do now?

I hear they have these anti burn videos built into plasma tv's do you think running something like this will help the screen burning or is it just a marketing gimmick?

I'm hoping Bell Canada replaces this phone and gives me a nice loaner pda phone to use while it's being repaired.
