像素驱动电路及像素驱动方法、阵列基板以及显示装置
摘要：
本发明提供了一种像素驱动电路。该像素驱动电路包括驱动控制模块、第一驱动模块以及第二驱动模块。驱动控制模块连接到数据线、第一扫描线、第二扫描线、第一电压信号端、第一驱动模块和第二驱动模块，并被配置为当第一扫描线输出有效电压信号时，控制第一驱动模块和第二驱动模块中的一者开启，以及当第二扫描线输出有效电压信号时，控制第一驱动模块和第二驱动模块中的另一者开启。第一驱动模块连接到驱动控制模块、第二电压信号端和发光模块，并被配置为在驱动控制模块的控制下驱动发光模块发光。第二驱动模块连接到驱动控制模块、第二电压信号端和发光模块，并被配置为在驱动控制模块的控制下驱动发光模块发光。本发明可减少驱动晶体管的阈值电压和迁移率随时间变化导致的显示不均匀现象。
摘要（英）：

The invention provides a pixel driving circuit. The pixel driving circuit comprises a driving control module, a first driving module and a second driving module, wherein the driving control module isconnected to a data line, a first scanning line, a second scanning line, a first voltage signal terminal, the first driving module and the second driving module and is configured to control one of thefirst driving module and the second driving module to be turned on when the first scanning line outputs an effective voltage signal and control the other of the first driving module and the second driving module to be turned on when the second scanning line outputs an effective voltage signal. The first driving module is connected to the driving control module, a second voltage signal terminal and a light emitting module and is configured to drive the light emitting module to emit light under the control of the driving control module. The second driving module is connected to the driving control module, the second voltage signal terminal and the light emitting module and is configured to drive the light emitting module to emit light under the control of the driving control module. The pixel driving circuit can reduce a phenomenon of nonuniform display caused by variations in threshold voltage and mobility of a driving transistor along with the time.
