像素补偿电路及AMOLED显示装置
摘要：
本发明涉及一种像素补偿电路及AMOLED显示装置。所述像素补偿电路包括数据信号写入模块、高电压写入模块、第一基准电压生成模块、驱动晶体管、电容和发光器件；所述数据信号写入模块在发光器件发光前与所述电容的第一端连接；所述高电压写入模块在发光器件发光过程中与电容的第一端连接；所述第一基准电压生成模块在发光器件发光前与电容的第二端、发光器件的阳极和驱动晶体管的漏极连接；所述驱动晶体管的栅极与电容的第二端连接，源极与高电压写入模块连接，漏极与发光器件的阳极连接；所述发光器件的阴极与公共接地电极连接。上述像素补偿电路可以避免发光器件在发光过程中的亮度发生变化，提高发光过程中的亮度均一性。
摘要（英）：

A pixel compensation circuit includes a data signal writing module, a high voltage writing module, a first reference voltage generation module, a driving transistor, a capacitor and a light emitting device. The data signal writing module is connected to a first end of the capacitor. The high voltage writing module is connected to the first end of the capacitor. The first reference voltage generation module is connected to a second end of the capacitor, an anode of the light emitting device and a drain electrode of the driving transistor. A gate electrode of the driving transistor is connected to the second end of the capacitor, a source electrode thereof is connected to the high voltage writing module, and the drain electrode thereof is connected to the anode of the light emitting device. A cathode of the light emitting device is connected to a common grounding electrode.
