Method for Improving Burn-in for RGBW OLED Displays

Description:

RGBW OLED displays. While there is only one combination of grey levels of R, G, B which realize a color in a RGB-pixel, there are numerous possible combinations of grey levels of R, G, B and W which can realize a color in a RGBW-pixel. Among the numerous possible combinations of grey levels of R, G, B and W, we selected specific combinations which suppress the peak of sub-pixels’ total accumulated amounts of illuminance so that burn-in can be slowed down. And we selected specific combinations which make the pattern of burn-in less artificial so that the burn-in still can occur but it can be felt less severe or less recognizable from a human perceptual view.
