OLED vs IPS - difference

[KrzysiuM]

Iam already using 4K monitor on ips with 144hz. Will there be a huge difference between 4K ips display vs oled one? Or should i wait for something better like newer versions of OLED Panel?

im sorry, but some movies and pictures of light/white images do exist

the leds are only on/off, no inbetween state
the appear light/dark by adjusting the pwm % (on vs off times) the pwm freq is in the khz range

for white, all it does is turn the pwm % to 100 for r/g/b subpixels

if you never look or check for a problem, you may will never know it exists until its blatantly obvious

Yes .. and that is a destructive thing to do on an OLED screen. It's fine for normal LCD Screens but should never be done on an OLED screen, even for a short time. An all-white static image on an OLED is literally destroying the screen every second that it's on. Don't do it.

If people do not see burn-in under normal usage conditions (NOT A BRIGHT WHITE SCREEN) then they don't care. It's not worth destroying the screen's pixels just to look for something.

no it is not bad to run a led at 100% its rated spec

again, they like a switch, on/off anytime the led is not at 0% pwm, it will be on for short periods at during its pwm frequency

you can lower the overall brightness of the display, or do a gray image, to see if there is any uneven lighting which would be an indicator of screen burn
but the displays overdriving can override grays to lighter white which would hide burned pixels making them the same shade of the gray, so white is better to use white image to see burned pixels

its like saying dont display anything white, as that will burn those pixels faster
which is true, but only if those specific pixels are left on longer than the rest
but all white image, will burn the entire display evenly which would not leave any noticeable burn

On a NORMAL SCREEN that is LED, LCD, IPS, VA, Etc, No it won't harm it but it's completely different on an OLED screen which is what you don't seem to understand for some reason.

You need to think of an OLED like a candle that's lit. Slowly over time the wax melts away until there's none left. That's what happens with an OLED screen when we use it. All OLED screens will very slowly get dimmer and dimmer over time. It's just part of the technology. If we use the screen normally then it's like a very small flame at the top of the candle, about the size of the head of a match. But if you have an OLED screen at 100% brightness with a solid white static image it's like placing the candle next to a space heater. It definitely will cause the screen to degrade a lot faster.

Maybe this might help you understand more: 5 minutes of sustained time displaying a static all white image on an OLED screen would be the same amount of degradation as multiple months of normal usage.

The whole problem with your suggestion is there is literally no reason at all to ever do this. Displaying an all white static image on an OLED is just degrading the screen rapidly for literally no reason. It's nothing like normal usage. That's just degrading the screen for the sake of degrading it, completely and utterly wasteful.

OLED's already typically only have about 7-10 years of usable lifespan as they are. No one should be reducing that at random for no reason.

the short time it takes to check for screen burn will not degrade the monitors lifetime by any amount of time

its not going to burn out all of the pixels instantly

Yes it will. I just explained that.

Displaying an all-white static image on an OLED for even a couple minutes will reduce it's usable life by multiple months.

No but there's no reason to do it. Just.. no. Never do it. Not when people are paying $700 - $1000+ for the screen already.

No one cares what you do with your own screens in your house. But when you are on the internet and offering suggestions to other people it's a completely different thing. You don't know them. They spent a lot of money on their screens. It's probably a good idea to NOT suggest things to them that you know will degrade their screens. That's called malicious intent.

Misinformation. Yes, 100% for RGB (or in my case WRGB) pixels will wear out the panel more than normal usage, but it will not cause super quick burn. If it was the case, you literally could never browse the web in fullscreen light mode.

In addition, the 27QHD240 has brightness compensator that automatically lowers max brightness (in SDR mode) for large, all-white parts (or whole screen), to prevent just that kind of damage. I imagine newer panels have similar features.

Sure. You can do that if you want your screen to last for 5 years of ownership instead of 7. It's your choice and your money. Personally I'll never do that with my OLED screen. I want it to last as long as possible.
