Abstract:
The present invention provides a GOA drive circuit and embedded type touch display panel. The GOA drive circuit comprises GOA units cascade coupled in multilevel, the nth level GOA unit comprises an output end pull down unit and an output control unit, both the output end pull down unit and the output control unit are employed to control a signal outputted by an output end of the nth level GOA unit, and one end of the output end pull down unit is coupled to a first end point, the first end point is loaded with a first signal, and one end of the output control unit is coupled to a nth clock signal, and as the embedded touch display panel enters signal interrupt and performs a touch scan, the output control unit is off to cut off an output path that the nth clock signal outputs to the output end.
