Abstract

The invention discloses a gate driving circuit, comprising a plurality of gate driving units in cascade, characterized in that the plurality of gate driving units respectively comprise an input moduleconnected with a first node and charging the first node according to a first start signal and a second start signal; a first output module connected to the input module at the first node, generatinga gate driving signal of the present stage according to the first clock signal, and providing the gate driving signal of the present stage at the output terminal; the second output module is connectedwith the input module to the first node, and generates a transfer signal of the current stage according to the first clock signal; a first pull-down module the pulls down the first node to the low level signal under the control of the second clock signal; and a stabilizing module which maintains the gate signal of the current stage at a low level under the control of the first clock signal and the second clock signal. The gate driving circuit can realize a narrow frame and a low power consumption display device, and reduce the occurrence of the cross ripple phenomenon.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly to a gate driving circuit and a display device. Background technique [0002] The liquid crystal display device is a display device that changes the light transmittance of the light source by using the phenomenon that the arrangement direction of the liquid crystal molecules changes under the action of an electric field. Due to the advantages of good display quality, small size and low power consumption, liquid crystal display devices have been widely used in mobile terminals such as mobile phones and large-sized display panels such as flat-panel TVs. Most of the liquid crystal displays on the current market are projection type liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules in the middle of two parallel glass substrates, and apply a driving ...
