3.1: A New AMOLED Pixel Compensating the Combination of n‐Type TFT and Normal OLED Device

A new AMOLED pixel circuit was proposed to compensate for the mismatched combination of n-type TFT and normal bottom-emission OLED. The proposed pixel also compensates for the variation of TFT characteristics and I×R voltage rise in power line. 15-inch AMOLED panel employing reliable a-SPC TFT backplane and the proposed pixel has been developed.
