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. The gate drive circuit comprises a plurality of levels of gate drive units. Each level of gate drive unit comprises a first switch element to a seventeenth switch element. Each level of gate drive unit receives a first clock signal. A first stabilizing unit is formed by the tenth switch element, the twelfth switch element, the fourteenth switch element and the sixteenth switch element. A second stabilizing unit is formed by the eleventh switch element, the thirteenth switch element, the fifteenth switch element and the seventeenth switch element. The invention further provides a display device. According to the gate drive circuit and the display device using the gate drive circuit, the switch elements playing a stable role and the switch elements playing a role in outputting gate drive signals receive different clock signals, the output capability of the gate drive circuit is higher, and the gate drive circuit comprises the two stabilizing units, so that stability is high.

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 ...
