Problems solved by technology

But at the same time, as the resolution and screen refresh rate of the display device continue to increase, the wiring space of the GOA circuit will also continue to increase, resulting in an increase in the size of the borders on both sides of the display device, making it difficult to meet the design requirements of narrow borders or no borders

Abstract

The invention provides a gate drive circuit and a display device, and belongs to the technical field of display. The provided gate drive circuit comprises a plurality of shift registers. Each shift register comprises an input sub-circuit, an output sub-circuit, a first reset sub-circuit and a second reset sub-circuit. Each input sub-circuit is configured to pre-charge a pull-up node under the control of an input signal. Each pull-up node is a connection node of each input sub-circuit and the corresponding output sub-circuit. Each output sub-circuit is configured to output a clock signal through a first signal output end under the control of the voltage of the corresponding pull-up node. Each first reset sub-circuit is configured to reset the corresponding pull-up node and the corresponding first signal output end through a first non-effective level signal under the control of a first reset signal. Each second reset sub-circuit is configured to output a second non-effective level signal through a second signal output end under the control of a second reset signal.

Description

technical field [0001] The present disclosure belongs to the field of display technology, and in particular relates to a gate drive circuit and a display device. Background technique [0002] The basic principle of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film transistor liquid crystal display) to realize a frame display is to input a square wave of a certain width to each row of pixels sequentially from top to bottom through the gate drive. strobe, and then through the source (source) to drive the signal required for each row of pixels to be output from top to bottom in turn. At present, the display device with such a structure is usually made of gate drive circuit and source drive circuit on the glass panel by COF (Chip On Film, chip-on-film) or COG (Chip On Glass, chip directly fixed on the glass) process. However, when the resolution is high, the output of the gate drive circuit and the source drive circuit will increase, and the length of the drive ci...
