Abstract
In our laboratory we have simulated, designed, and fabricated hydrogenated amorphous silicon (a-Si:H) thin-film transistors (TFTs) based pixel electrode circuits for active-matrix organic light-emitting displays (AM-OLEDs). These pixel circuits, having very small feed-through voltages, can supply a continuous output current at an adequate level for AM-OLEDs up to 500 dpi of resolution. Each pixel electrode has also compensation circuits that will allow to adjust the output current level for the OLED and a-Si:H TFTs threshold voltage variations. Therefore, we can control display brightness uniformity at an acceptable level.
