8.1: Invited Paper: Advancements and Outlook of High Performance Active-Matrix OLED Displays

By introducing new terminology, active-matrix OLEDs advanced performance can be well characterized. “Luminous Flux” and Assured Dynamic Range” better represent the viewers impression than previous terminology such as “front luminance” and/or “viewing angle.” Compensation circuit, low-stress driving technique, CVD condition, TFT shape, and high-efficiency OLEDs are the keys to enabling low-cost a-Si AMOLED manufacturing in order to compete with other display technologies.

P-70: Image Sticking Measuring Method by Usage Model

Two quantities, effective intensity and effective current density, are defined. By measuring luminance degradation of areas varying in current density at different time intervals and determining these quantities, image sticking can be measured and accurately simulated for representative image sets on RGBW and RGB OLED displays using only one image.
