Problems solved by technology

[0003] Due to the large number of signal lines in the GOA and the dense arrangement, it is easy to accumulate charge. When the charge accumulates to a certain extent, the gate drive circuit is very prone to the risk of explosion, causing the panel to display abnormally.

Abstract

The invention discloses a gate drive circuit of a display panel, a display panel and a display device. The gate drive circuit includes a clock signal line to provide a clock signal; multiple cascaded gate drive units receive the clock signal, each The gate driving unit at the stage is configured to drive a scanning line; a reset signal line provides a reset signal for the gate driving unit; and an electrostatic protection device, one end of the electrostatic protection device is connected to the reset signal line, and the other One end is connected to the discharge line of the display panel, and the electrostatic protection device releases the static electricity in the reset signal line to the discharge line. The present invention releases the static electricity in the reset signal line by connecting the reset signal line to the electrostatic protection device. static electricity, which enhances the protection ability of the reset signal line, thereby effectively reducing the risk of static electricity explosion and improving the stability of the gate drive circuit.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit of a display panel, a display panel and a display device. Background technique [0002] With the development and progress of science and technology, flat panel displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. The flat panel display includes a thin film transistor liquid crystal display (ThinFilm Transistor-Liquid Crystal Display-play, TFT-LCD) and an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display. Among them, GOA technology (Gate Driver on Array) is an array substrate row drive technology, which can use the array process of liquid crystal display panels to manufacture the gate drive circuit on the array substrate to realize the driving method of progressively scanning the gate. GOA technology can reduce the welding (bonding) process ...
