Abstract

The invention provides a GOA circuit. According to the GOA circuit, an electric leakage inhibition module is arranged, and electric leakage of a first node is inhibited when an embedded type touch control display panel enters a stage in which a signal is interrupted and touch control scanning is carried out, so as to maintain high level of the first node, thereby reducing the risk of level transmission failure, and making the GOA circuit more stable.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a GOA circuit. Background technique [0002] GOA (Gate Driver on Array) technology is array substrate line drive technology, which uses the thin film transistor liquid crystal display array process to manufacture the gate scanning drive circuit on the thin film transistor array substrate to realize the driving method of progressive scanning. [0003] At present, with the mature development of the integrated touch panel technology, the display panel will choose to embed the touch display panel. In the embedded touch display panel, because the display refresh time is separated, the touch scanning is done in the free time (TP pause time), so the working state of the GOA circuit of the panel is no longer continuous, but every scan A certain number of stages, keep for a period of time, continue to scan. In this way, when the GOA circuit is in the holding state, the problem of c...
