We report on active matrix-organic polymer light-emitting displays AM-OLEDs based on a three hydrogenated amorphous silicon a-SiH thin-film transistor TFT pixel electrode circuit that supplies a continuous output current to organic polymer light-emitting devices OLEDs. The output current level drifts induced by either process variations or devices aging can be reduced in this design by adjusting the driver TFT operating point with the active resistor. Our first green light-emitting engineering prototype had a brightness of 120 cdsq m and fill factor of about 45.
