Title almost says it all. OLED monitors are getting more and more affordable, but it’s almost out of the picture when buying a monitor because of toolbars and HUD elements. I don’t understand why monitors “burn-in”, when I shine my LED flashlight or some LED xmas lights they won’t simply start emitting the same light even when I turn them off. I know it’s a dumb comparison, but still, what happens?
The other thing that I don’t understand is the fact that I’ve never seen any signs of burn-in on anyone’s phone. Alright, technically that’s a lie, I did see some on a work phone (or two), that only had some chat app open, seemingly since ages, and the namebar was a bit burned-in, or something like that, as you’d guess I also didn’t interact with that phone a lot. As as said above “but still,” I’ve had my phone for a while now, so does my family and friends, some of us even doomscroll, and I’ve never seen any signs of burn-in on any (actually used) phone.
so, I can watch my background all day, but I should open my browser every like 3 hours press f11 twice and I’m safe? Ff I’m away just let the screensaver save my screen? In that case why would anyone ever worry about burn it, you almost have to do it intentionally. But if it’s really dangerous, like I immerse myself into a youtube video, but it has the youtuber’s pfp on the bottom right (does youtube still do that?), and it was hbomberguy’s, am I just done, toasted, burnt-in?
How long have you had your phone? I have seen it begin to happen around the three year mark on my Galaxy S8+ and my S20+. Slight ghosting of parts of the Wayz UI. My S23 Ultra hasn’t yet, but still have a while on it.
mine has it from the navbar
Burn-in is a misnomer.
OLEDs don’t burn their image into anything. CRTs used to burn in right onto the screen making it impossible to fix without physically changing the “glass” (really the phosphor screen).
What happens is the OLED burns out unevenly, causing some areas to be weaker than others. That clearly shows when you try to show all the colors (white) because some areas can no longer get as bright as their neighboring areas. It is reminiscent of CRT burn-in. LCDs just have one big backlight (or multiple if they have zones) so unevenness from burnout in LCDs is rarely seen, though still a thing.
So, OLED manufacturers do things to avoid areas from burning out from staying on for too long like pixel shifting, reducing refresh rate, or dimming areas that don’t change for a long time (like logos).
There is a secondary issue that looks like burn-in which is the panel’s ability to detect how long a pixel has been lit. If it can’t detect properly, then it will not give an even image. This is corrected every once in a while with “compensation cycles” but some panels are notorious for not doing them (Samsung), but once you do, it removes most commonly seen “burn-in”.
You’d have to really, really leave the same image on your screen for months for it to have any noticeable in real world usage, at least with modern OLED TVs. You would normally worry more about the panel dimming too much over a long period of time, but I don’t believe lifetime is any worse than standard LCD.
TL;DR: Watch RTings explain it
People leave a tv on a 24h news channel with a logo that never moves. Or play a game that has certain elements of the GUI that never move. That’s how it happens most often, I think.
My pixel 3a had burn in after 3 years. It’s the screen gui elements that rarely change that show the burn in. On android that’s the message bar at the top and the white line task switch at the bottom.
I’ve been hearing “OLED burn in is better now” ever since I got my Galaxy Nexus 12 years ago. But it still seems to last only 3 years.
