«One 2008 technical report on an OLED TV panel found that after 1,000 hours, the blue luminance degraded by 12%, the red by 7% and the green by 8%. In particular, blue OLEDs at that time had a lifetime of around 14,000 hours to half original brightness (five years at eight hours per day) when used for flat-panel displays. In 2016, LG Electronics reported an expected lifetime of 100,000 hours, up from 36,000 hours in 2013. A US Department of Energy paper shows that the expected lifespans of OLED lighting products goes down with increasing brightness, with an expected lifespan of 40,000 hours at 25% brightness, or 10,000 hours at 100% brightness»
By the time five years (at least) have passed, there will be even better tech. But OLED is the best tech today.
