Impact of long-term stress on the light output of a WRGB AMOLED display [PDF]
, 2016 This paper describes how long-term use impacts the light output of a commercial 55' WRGB AMOLED display with InGaZnO TFT backplane. This covers effects which are known by the terms 'aging', 'image-sticking,' and 'burn-in.' The focus is on three different
