Title: GOA DRIVE CIRCUIT AND EMBEDDED TOUCH CONTROL DISPLAY PANEL
Abstract:
Disclosed are a GOA drive circuit and an embedded touch control display panel. The GOA drive circuit comprises multi-stage cascading GOA units (10), wherein an nth-stage GOA unit (10) comprises an output end pull-down unit (400) and an output control unit (600), and the output end pull-down unit (400) and the output control unit (600) are both used for controlling a signal (G(n)) output by an output end of the nth-stage GOA unit; one end of the output end pull-down unit (400) is electrically connected to a first end point (L), and the first end point (L) loads a first signal; one end of the output control unit (600) is electrically connected to an nth clock signal (CK(n)); when an embedded touch control display panel enters a state of signal stop and carries out touch control scanning, the output end control unit (600) is turned off so as to cut off an output path of the nth clock signal (CK(n)) to the output end, and the output end pull-down unit (400) is started so as to enable a first signal to be output through the output end of the GOA unit (10); and when the embedded touch control display panel enters the state of signal stop and carries out touch control scanning, the first signal is a signal consistent with a touch control scanning signal of the embedded touch control display panel.
