Problems solved by technology

[0003] In the prior art, when the GOA drive circuit and touch technology are combined and applied, usually, when the panel is working normally, the advanced GOA circuit drives the scan, and after all the gate line scans are completed, the touch signal output scan is performed. , there is no interruption in the process of GOA circuit driving scanning, so the frequency of GOA circuit driving scanning is consistent with the frequency of touch signal output scanning, that is, one GOA circuit driving scan can only correspond to one touch signal output scanning, which limits the touch control scanning frequency

Abstract

The invention discloses a GOA driving circuit applied to a flat panel display and a flat panel display. The GOA driving circuit includes a front circuit, a middle circuit and a rear circuit, wherein all of the front circuit, the middle circuit and the rear circuit are The GOA drive subunit respectively receives the first clock signal and the second clock signal to sequentially generate corresponding gate drive signals, and an interrupt period is set in the first clock signal and the second clock signal to sequentially An interruption is generated between the generated corresponding gate driving signals, and the flat panel display performs a touch detection operation in the interval of the interruption. Through the above method, the present invention can realize the scanning interruption of the GOA driving circuit and increase the touch scanning frequency.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a GOA driving circuit applied to flat panel displays and the flat panel display. Background technique [0002] The gate driver on array GOA (gate driver on array GOA) has the advantages of lower production cost and narrow frame design, and has been gradually applied in the field of liquid crystal display (LCD); at the same time, it can provide a natural interface touch between the electronic system and the user Sensing technology has also been widely used in various fields, especially in-cell touch, which has the advantages of thin thickness and sensitive touch. [0003] In the prior art, when the GOA drive circuit and touch technology are combined and applied, usually, when the panel is working normally, the advanced GOA circuit drives the scan, and after all the gate line scans are completed, the touch signal output scan is performed. , there is no interruption in the process...
