but you will be shortening it's lifespan wearing down the buffer of all the other emitters to match your consistently abused area(s).Ī taskbar, persistent toolbar, or a cross of bright window frames the middle of the same 4 window positions or whatever. So you could be fine abusing the screen outside of recommended usage scenarios for quite some time thinking your aren't damaging it, and you aren't sort-of. As far as I know there is no way to determine what % of that buffer is remaining. However, with the ~25% wear-evening routine buffer you won't know how much you are burning down the emitter range until one day you realize that you've bottomed out that buffer. Primarily that, but along with the other brightness limiters and logo dimming, pixel shift, and the turn off the 'screen'(emitters) trick if utilized, should extend the life of the screens considerably. To answer your second question about lifespan, I'm pasting one of my other replies here from other conversations:įrom what I read the modern LG OLEDs reserve the top ~ 25% of their brightness/energy states outside of user available range for their wear-evening routine that is done in standby periodically while plugged in and powered.

There are other articles about it online if you look around. It also senses any TFT (Thin Film Transistor) voltage changes during power off to detect and correct pixel degradation by comparing it with a set reference value.

The Pixel Refresher feature, built into LG OLED TVs, automatically detects pixel deterioration through periodic scanning, compensating for it as needed. To answer your first question - LG's system compares the oled emitters to a set of reference values, checking for voltage fluctuations to the emitters/transistors during times the screen has been off for awhile.
