A Novel a-InGaZnO TFT Based Voltage Programmed Pixel Circuit to Compensate Threshold Voltage and Mobility Variations
Yongchan Kim, Jerzy Kanicki, and Hojin Lee
Abstract
In this paper, we proposed a novel voltage-programmed pixel circuit based on amorphous indium gallium zinc oxide thin-film transistor (a-InGaZnO TFT) for active-matrix organic light-emitting display (AMOLED) with an enhanced electrical stability and uniformity. Through an extensive simulation work based on a-InGaZnO 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.
