A Novel P-type LTPS Pixel Circuit for AMOLEDs with Dual-Compensation Function

Abstract
In this paper, we proposed a novel voltage-programmed pixel circuit with p-type low temperature polycrystalline-silicon thin film transistor (LTPS TFT) for active-matrix organic light-emitting display (AMOLED) with an enhanced electrical stability and uniformity. Through an extensive simulation work based on p-type LTPS TFT and OLED experimental data, we confirm that the proposed pixel circuit can compensate for both mobility variation and threshold voltage shift of the driving TFT.
