摘要

提出了一种应用于有源矩阵有机发光二极管(amoled)的非晶硅(A - si)薄膜晶体管(TFTs)及其外部驱动器的新型电压程序化像素。所提出的像素电路是一个只有2个控制信号的3- TFT结构。这种像素结构及其驱动器补偿了tft阈值电压的偏移，降低了OLED对tft W/L的电流灵敏度。

A novel 3-TFT AMOLED pixel driver for threshold voltage shift compensation

A new voltage-programmed pixel using amorphous silicon (a-Si) thin film transistors (TFTs) for active matrix organic light-emitting diodes (AMOLEDs) and its external driver is presented. The proposed pixel circuit is a 3- TFT structure with only 2 controlling signals. This pixel structure along with its driver compensates for the shift in TFTs threshold voltage and reduces current sensitivity of OLED to W/L of TFTs.
