OLED also has disgusting streaking issues. Both my Galaxy S3 and Vita have black splotches that are easily visible on a dark background.

Vita OLED burn in.

Launch system here. No burn in. I do have small scratches but that's my fault for not using a screen protector.
Yeah, I have that since I have the vita. Only visible during pure black transitions. You can see black... spots on the screen over the normal "gray" black.
Hmm that sucks..haven't noticed it on mine yet. I have it set to the maximum time before screen-off and I've left it on the PSASBR title screen loads of times! I remember once I don't think it even turned off after 10minutes :S
Mura becomes a non-issue, don't think I've noticed the splotches in months, not even sure if they are still there for me.
TBH I'm looking to buy an OLED tv once they are out, the quality is just too much of an improvement, same with my Note II. Hopefully they improve the durability of the tech.

Sorry for the bump, but hey! At least I searched before posting.
Just found out about this today. I thought the screen protector I had put on had some residue/moisture stuck behind it, and upon Googling, I found that it was something different. I was about to rip the protector off too..
Not too bad, but terribly distracting nonetheless. (During loading screens.)

What image is burned in, if you don't mind sharing? Was it something you kept on for a long time?
I wouldn't call it burned in, more like.. splotchy. It looks like the image above, just not as green.
It definitely looks like a poorly placed screen protector too. I've seen the burn-in issues over the past few pages, definitely not like that. Light use, always keep the brightness setting all the way down.
That doesn't look like burn-in. Looks like the splotchy phase that most Vita screens seem to go through for the first few dozen hours. I had a bunch of gunky stuff visible during Uncharted GA loading screens for a month or so when I bought mine last year. Gone now.

just noticed mines got 2 burn-ins.
Got one across top where the status bar is and another where the browser bar is on right side.
cant really notice it except for on purple background (got purple for my 1st bubble set and messages).
I bought a FEB unit but had it shipped to sony a few months later for a analog problem....hope I get a year warranty from that date or im screwed

That's the mura effect, not burn-in. It's normal, and can only be noticed on mostly black screens in the dark.
I don't think it will. I think its inherent to the way it (the screen) is produced and fitted. Could be wrong.
No, it's inherent to OLED tech for now. You'll see it on samsung smart phones as well. You'll have to live with it.

I remember my old TV had burn in.... pausing in Red Dead Redemption for a few minutes was a problem.
Yeah, so I noticed that there is burn in on my Vita. Very noticeable during black loading screens. I'm a sad panda now
If it's during black loading screens that's not burn-in, but mura:

Yuck! So glad I only have one horizontal line! and that to is neatly drawn lol!

I noticed this too on my Vita. Seeing how that only appears during things like loading screens where the screen is completely black I don't have a problem with it.
Me neither.
It's still a great screen considering the unit is a mere $200 when on sale. But then again, I also like the 3d on the 3ds, so maybe don't take my advice on screen quality.
The thing about mura is that even the "bright" parts of an oled screen with mura displaying black are much darker than any LCD displaying black. As such, if you consider any light produced while showing a black screen a screen issue (as IMHO you should), even an OLED with significant mura is still far better off than any LCD display.
I made an image illustrating this last year:

Is the picture posted by Takao making things look much worse than they are? Because that's the only way that LCDs could potentially be worse than this.
The picture Takao posted doesn't show an LCD screen's black level to compare. Mine does.

I haven't heard of this. Thankfully this hasn't happened to me...now I know to be vigilant...

I'm not sure what the point of that picture is? I mean, why use a 4 second exposure time? It just makes the LCD panels look way worse than they are, no? And of course the OLEDs are gonna be black. They emit no light.
Got the same problem as you , it's really ugly and make the hardware looks cheap when on black screen (loading mostly) .
No problem in game I can barely notice it
I have a Vita with this issue and yeah, Takao's image really exaggerates it to make it more visibile in a photo. It's a bit more subtle than that in actual use.
The point of the 4 second exposure time is to show the difference. If all OLED displays emitted no light with black screens there wouldn't be mura to worry about. As that is not the case, the picture is intended to show that even with mura, OLED black levels are still incredibly superior to LCD. Which it does. (Also, if you look at the picture in some photo editing application, you'll see that the OLED screens aren't actually black -- the Vita is brighter than the S2 and has mura)

It doesn't. I mean it may do, but that's not the real black level that I see on my monitor, so imo that comparison is BS.
Ah, I see. Fair enough!
Better to ask Samsung, they're the ones who actually make the damn screens.
Well, it uses a CCD sensor in a digital camera to measure the light output of each device in the same environment. I don't know what else I could do to make the comparison better.

Simple (imo): take a Vita and an LCD screen and put them next to each other. If possible the Vita with Mura effect. And try to take a picture that's as close to real world conditions, i.e. how your eyes see it, as possible. Because after all that's what counts imo.
The odd thing is, AMOLED/OLED burn in has improved significantly over the last couple of years. Makes you wonder why the Vita screens continue to have this problem.
So what you're really saying is "Science - How does it work?"
He increases the exposure time to amplify the delta. The ratios to one another are all the same, but the sample size has been increased to make it readily apparent.
A "real world" screen shot doesn't highlight the gap clearly enough for easy comparison, despite the fact that your eye still inherently registers the difference in black level. His example shows why.
Equal amplification is a long used scientific practice.
If you put a Vita next to a LCD and take a "real-world" picture, the LCD will look gray (dark gray if it has good contrast) and the Vita will be totally black (regardless of any mura present). Is that really helpful?
Sony probably went for the cheapest displays Samsung offered.
Yup - if you put them side by side, LCD(say, IPad3 one) in complete darkness is more than bright enough to completely drown out any light-leakage on Vita(or other OLED) screen - even to the human eye (camera sensors have even less chance to pick it up).Durante said:
Actually it looks a lot like that to human-eye if you observe it in complete darkness - I've done that test before too(without side-by-side, as I wanted to see the actual light-leaking on OLED as well).Frankfurter said:
Ultimately mura is only visible in darkness, and LCDs are flash-lights in those conditions.

I can't tell you if it's more helpful until I have seen it.
Edit: What I'm trying to get at is that I don't know why you'd just chose a 4 seconds exposure time. Let's just say that LCD monitor would have a 100times better black level than they one you used for the comparison (that kind of black level probably doesn't exist for LCDs, but anyway). You could still get the same kind of difference by simply raising exposure time to 20 seconds or 50 seconds or 5 minutes. But that's not showing the difference that our eyes will see between these 2 displays (in the latter case there probably would be basically zero difference).
Because Mura's effect is on black levels. Yes it affects the quality of the image, but even with Mura, an OLED screen is several orders of magnitude better than a run of the mill LCD panel. Hence the OLED screen with Mura will still look leagues better.
I don't quite see how the Vita "continue to have this problem" when a very small percentage of users report burn in on the Vita and mura is just a nature of OLED technology that while improving is still present and, most importantly, completely benign as it doesn't show up during game play.
All screens can burn in if put in the right circumstances. There is a reason the Vita, like all other screen carrying products, have brightness settings and display timers. They're meant to be used, not for you to ignore and all but disable in an attempt to burn out both your retinas and your screen.
Because what your eye finds appealing and what you can consciously separate as superior are two entirely different things.
A rock solid 30 fps versus a solid 60 fps isn't something most people can inherently pick out, but the 60 fps game unequivocally feels smoother to all users. How then do you outline the importance of frame rate to someone who can't pick out the difference on their own?
You proportionally scale both the 30 fps source and the 60 fps source down (as lower frame rate results in more perceptible difference) until the person sees the divide.
It's the same with Durante's image. In order to make the difference readily apparent he scales the exposure up to highlight amplify that delta without changing the ratio of said delta.
Your eye might not see an LCD as being that gray, but it definitely notices how washed out blacks look on them. Durante's image outlines the reason why blacks look so much nicer on OLEDs in a way even passing observation can pick out.
I'll take that picture for you later today. I just don't think it will be nearly as helpful for comparison as the one I posted -- it will just be a gray rectangle floating in space.
