像素驱动电路及有机发光二极管显示器
摘要：
本发明提供了一种像素驱动电路及具有该像素驱动电路的有机发光二极管显示器。该像素驱动电路采用6T2C像素结构，以对像素中驱动薄膜晶体管的阈值电压进行有效补偿，使流经有机发光二极管的电流与驱动薄膜晶体管的阈值电压无关，从而消除因第一薄膜晶体管的阈值电压漂移而引起的画面显示不良的现象。
摘要（英）：

A pixel (PX) drive circuit and an organic light-emitting diode (OLED) display having said pixel (PX) drive circuit. The pixel (PX) drive circuit uses a 6T2C pixel structure to effectively compensate a threshold voltage Vth driving a thin film transistor (T1), so that a current flowing through the OLED is irrelevant with the threshold voltage Vth driving the thin film transistor (T1), thereby eliminating poor image display due to a threshold voltage Vth drift of a first film transistor (T1).
