本文介绍了一种用于有源矩阵有机发光二极管显示器的高速电压编程像素电路,该电路采用阈值电压一次性检测法。所提出的像素电路由一个驱动薄膜晶体管(TFT)、四个开关TFT、两个电容和四条控制信号线组成,可以有效地补偿驱动TFT的阈值电压漂移和OLED退化。通过巧妙地利用电容耦合效应实现了一次检测法的阈值电压,并与传统的驱动方案进行了比较,得到了很好的验证。在这种方法中,数据直接更新,而不需要从第二帧开始的初始化和阈值电压检测周期。此外,该方法也可应用于其他补偿像素电路。
This letter presents a high-speed, voltage-programmed pixel circuit for active-matrix organic light-emitting diode displays employing threshold voltage one-time detection method. The proposed pixel circuit that consists of one driving thin-film transistor (TFT), four switching TFTs, two capacitors, and four control signal lines can effectively compensate for the threshold voltage shift of the driving TFT and the OLED degradation. The threshold voltage of one-time detection method is realized by an ingenious application of capacitor coupling effect, and it is well-verified by comparing it with the conventional driving scheme. In this method, data is directly renewed without the periods of initialization and threshold voltage detection from the second-frame beginning. Moreover, this method can also be applied to other compensation pixel circuits.
