OLED Burn-In Issue Among Non-OLED Producers
January 27, 2020
While the regularity and seriousness of OLED burn-in is often overstated (usually by manufacturers who don't produce OLED sets), the fact is that OLEDs absolutely can suffer from burn-in, and that it's usually fixed, static images such as logos that are the cause. Philips has has developed a new logo identifier is designed to almost entirely eradicate the problem caused by logos. Once enabled, it scans whatever's currently playing for any static images and carefully maps them using a series of little squares. It applies a localized dimming effect that prevents the logo from causing an issue for the panel. The precision of the scanning probably needs some tuning area of screen much larger than the logo is dimmed, at least for purposes of the demonstration. In actual home use, the dimming will apparently be more gradual and perhaps therefore less noticeable. Besides, even if the area dimmed is a little larger than the scan might suggest, its efficacy could still win it lots of fans. Philips's has been developing the technique for a long time claims it solves 95 per cent of burn-in issues.
Why the panel makers don’t use some form of real time sensing of sub-pixel aging is still a mystery to us.
