Problems solved by technology

[0005] However, for a large-sized liquid crystal display panel, the load driven by the gate drive circuit is very large, and the display uniformity is high, so the gate drive circuit is required to output a large and stable gate voltage. Drive signal, the prior art generally solves the above problems by increasing the number and size of switching elements and capacitors in the gate drive circuit, but the above method is not conducive to the design of the narrow frame of the liquid crystal display device, and the power consumption is large

Abstract

The invention discloses a gate drive circuit, comprising multiple stages of gate drive units, wherein each stage of gate drive unit comprises a first switch element to a thirteenth switch element. Each stage of gate drive unit receives a first clock signal, a second clock signal, a third clock signal, a first sequence signal and a second sequence signal, wherein the fourth switch element, the sixth switch element, the eighth switch element, the tenth switch element and the twelfth switch element form a first stabilization unit; the fifth switch element, the seventh switch element, the ninth switch element, the eleventh switch element and the thirteenth switch element form a second stabilization unit. The invention also provides a display device. According to the gate drive circuit and the display device using the gate drive circuit, disclosed by the invention, the switch elements for stabilizing and the switch elements for outputting gate drive signal receive different signals, so that the output capacity of the gate drive circuit is strong, and the gate drive circuit comprises two stabilization units, thus the stability is good.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gate drive circuit and a display device. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as lightness, lightness, energy saving, and no radiation, so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Taking a thin film transistor (Thin Film Transistor, TFT) liquid crystal display device as an example, it includes: a liquid crystal display panel and a driving circuit, wherein the liquid crystal display panel includes a plurality of gate lines and a plurality of data lines, and two adjacent gate lines The polar line intersects two adjacent data lines to form a pixel unit, and each pixel ...
