摘要

本文介绍了一种5T2C像素电路，用于补偿有源矩阵-有机发光二极管(AMOLED)显示器中TFT v值的变化。仿真结果表明，当驱动晶体管的阈值电压变化为±1V时，发射电流误差减小到10%以下，在中高电平灰度下，发射电流误差甚至小于5%。将该像素电路应用于CSOT的15英寸IGZO TFT - AMOLED面板显示，照明结果表明，该像素电路可以大大提高显示发光的均匀性。

A High Accuracy 5T2C Compensation Circuit used in IGZO TFT_AMOLED Displays

We introduce a 5T2C pixel circuit in this paper to compensate TFT Vth variation in active matrix-organic light emitting diode (AMOLED) displays. Simulation results show that the emission current error is decreased to less than 10% with ±1V threshold voltage variation of the driving transistor, which is even less than 5% in middle and high level gray. This pixel circuit was used in the 15 inch IGZO TFT - AMOLED panel display of CSOT, and the lighting results show that the pixel circuit can greatly improve the uniformity of display’s luminescence.
