Abstract:
The invention provides a GOA driving circuit applied for a flat panel display device and a flat panel display device. The GOA driving circuit includes a front-stage circuit, a middle-stage circuit and a rear-stage circuit. GOA driving subunits in the front-stage circuit, the middle-stage circuit and the rear-stage circuit receive a first clock signal and a second clock signal to sequentially generate corresponding gate driving signals. The first clock signal and the second clock signal are set with an interruption period to generate an interruption between the sequentially generated gate driving signals. The flat panel display device performs a touch detection operation in the interruption period. By the above solution, the invention can achieve the interruption of GOA driving circuit scan and thereby increase touch scan frequency.
