驱动电路和方法、移位寄存器、像素单元和显示装置
摘要：
本发明提供了一种驱动电路和方法、移位寄存器、像素单元和显示装置。所述驱动电路包括驱动放大模块、触摸屏驱动模块和分时驱动控制模块，分时驱动控制模块根据第一控制信号和第二控制信号发出分时驱动控制信号；驱动放大模块根据所述分时驱动控制信号，在OLED驱动阶段驱动所述OLED，在触摸屏驱动阶段放大触摸传感器输出信号，并控制所述触摸屏驱动模块根据触摸控制信号和放大后的触摸传感器输出信号驱动触摸屏。本发明对OLED和触摸屏进行分时驱动，从而以较少的器件即可以完成对OLED和触摸屏的驱动，同时能够有效OLED驱动信号和触摸屏驱动信号之间的互相串扰。
摘要（英）：

The invention is directed to a drive circuit, drive method and a shift register for a display device with touch control function. The drive circuit includes a driving and amplifying module, a touch screen driving module and a time-sharing drive control module. The time-sharing drive control module is adapted to send a time-sharing drive control signal according to a first control signal and a second control signal. The driving and amplifying module is adapted to drive the OLED during an OLED drive phase according to the time-sharing drive control signal, amplify a touch sensor output signal during a touch screen drive phase and control the touch screen driver module to drive the touch screen according to a touch control signal and the amplified touch sensor output signal.
