P-172: Temperature Distribution in WRGB AMOLED Displays

This paper explains how a non-uniform temperature distribution arises across an OLED display and how it is influenced by the image content. IR camera measurements on a sample 55” WRGB OLED display and a thermal model that allows simulating the temperature distribution across an OLED display are presented. It has been shown before that temperature has a direct impact on the picture quality of an OLED display. Therefore, a good understanding of the thermal behavior of an OLED display is important. The presented thermal model can be a useful tool in the design phase of an OLED display.
