摘要

提出了一种由非晶铟镓锌氧化物薄膜晶体管(A - igzo TFTs)组成的新型立体三维有源矩阵有机发光二极管(AMOLED)像素电路。该像素电路采用一列共享外电路，结构简单，能有效补偿a-IGZO TFTs的阈值电压变化。因此，可以有效地改善显示器的孔径比和亮度均匀性。仿真结果表明，在整个输入数据范围内，所提出的像素电路的相对电流误差率小于7%。

Novel a-IGZO pixel circuit adopting external circuit for use in 3-D AMOLED displays

A new stereoscopic three-dimensional (3-D) active-matrix organic light-emitting diode (AMOLED) pixel circuit composed of amorphous indium-gallium-zinc-oxide thin-film transistors (a-IGZO TFTs) is presented in this paper. The proposed pixel circuit has simple structure by adopting external circuit shared in one column and successfully compensates for the threshold voltage variation of a-IGZO TFTs. Therefore, the aperture ratio and brightness uniformity of displays can be ameliorated effectively. Simulation results show that the relative current error rates of the proposed pixel circuit are less than 7% over the entire input data range.
