A study of burn-in damage in OLED TVs found severe degradation around the panel edges, particularly in older WOLED designs. After 18,000 hours of accelerated longevity testing, 14 of the 16 LG TVs tested developed dead pixels and visible deterioration. The three QD-OLED Samsung TVs displayed no such issues.
The ongoing study comes courtesy of the TV and monitor testers at RTINGS, which looks at the long-term image retention issues faced by OLED TV technologies. However, it also found unique deterioration in some TV panels, particularly around the edges.
RTINGS calls the phenomenon "edge rot" and makes it clear this has nothing to do with burn-in, but may instead be a manufacturing defect or damage to the protective layers that keep moisture out of the panel. As those layers fail, moisture may damage individual pixels and short them...
