Gate drive circuit, display substrate and display device

Abstract

The invention provides a gate drive circuit, a display substrate and a display device, relates to the technical field of display, and aims to solve the problems that due to the fact that an existing gate drive circuit cannot provide appropriate signals according to the characteristics of a transistor controlled by the gate drive circuit, the provided signals cannot be well matched with the characteristic requirements of the transistor, and a display product is liable to flicker under low-frequency driving. The gate drive circuit comprises a plurality of first shift register units and a plurality of second shift register units; the first shift register unit is respectively coupled with a first high-level signal input end and a first low-level signal input end; the second shift register unit is respectively coupled with a second high-level signal input end and a second low-level signal input end; the first high-level signal input end and the second high-level signal input end are configured to be connected with different input ends; the first low-level signal input terminal and the second low-level signal input terminal are configured to connect different input terminals.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, a display substrate and a display device. Background technique [0002] Currently, display products generally include a pixel drive circuit and a gate drive circuit, wherein the pixel drive circuit is located in the display area of ​​the display product, and the gate drive circuit is located in the non-display area of ​​the display product. The gate drive circuit is used to provide corresponding signals for the transistors in the pixel drive circuit to control the transistors to be turned on and off. [0003] However, the existing gate drive circuit cannot provide a suitable signal according to the characteristics of the transistor it controls, so the signal it provides cannot match the characteristic requirements of the transistor well, which in turn makes the display product prone to flicker under low-frequency drive. And other issues. Contents...

Problems solved by technology

[0004] The purpose of the present invention is to provide a gate drive circuit, a display substrate and a display device, which are used to solve the problem that the existing gate drive circuit cannot provide suitable signals according to the characteristics of the transistors controlled by it, resulting in that the signals provided cannot be very fast. The characteristic requirements of well-matched transistors lead to problems such as flicker (Flicker) in display products under low-frequency drive
