摘要： The present invention provides a gate driving circuit and a driving method thereof, a display device, which relates to the field of display technology. The gate driving circuit may comprise a plurality of mutually cascaded shift register units and a pre-charging unit, the gate row drive scanning and touch control scanning of the plurality of mutually cascaded shift register units are performed alternately. By additionally arranging a pre-charging unit connected with the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished, the first stage of shift register unit can be pre-charged during the touch control scanning. In this way, the electric leakage phenomenon of the pull-up control node (PU point) of the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished due to a relatively long touch control scanning time interval between outputs of two rows of shift register units is avoided, thereby avoiding the defect of insufficient charging rate of row of pixels while ensuring touch control scanning of high report rate.
摘要翻译：本发明提供一种与显示技术领域相关的门驱动电路及其驱动方法，显示装置。栅极驱动电路可以包括多个相互级联的移位寄存器单元和预充电单元，交替执行多个相互级联的移位寄存器单元的栅极行驱动扫描和触摸控制扫描。通过在完成触摸控制扫描之后再次执行栅极行驱动扫描时，另外布置与相应的第一级移位寄存器单元连接的预充电单元，可以在触摸期间预充电第一级移位寄存器单元控制扫描。以这种方式，当触摸控制扫描完成后，由于相对较长的触摸而完成了栅极行驱动扫描时，对应的第一级移位寄存器单元的上拉控制节点（PU点）的漏电现象避免了两排移位寄存器单元的输出之间的控制扫描时间间隔，从而避免了像素行的充电率不足的缺陷，同时确保了高报告率的触摸控制扫描。
