A scheme of driving AMOLED displays with amorphous silicon (a-Si) thin film transistors (TFTs) is presented. By exploiting current feedback, a transresistance amplifier as column driver, and an accelerating current pulse, the driving scheme provides fast programming and low sensitivity of OLED current to shift in VT in a-Si TFTs. Prototypes of the pixel circuit and the transresistance amplifier were...
