Abstract

The invention discloses a shift register, a gate drive circuit and a display device, when a pull-up node is at a low level, the shift register controls a first noise reduction module to be conducted through a third signal control end and provides a low-level signal of a first power supply end to the pull-up node, so that the signal of the pull-up node is pulled down, noise is reduced, and the display effect is improved. Therefore, the problem that noise interference is generated to the gate driving signal output end when the clock signal provided by the clock signal end is high level is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a shift register, a gate driving circuit and a display device. Background technique [0002] As a display component of an electronic device, a display device has been widely used in various electronic products, wherein a gate driving circuit is an important component of the display device. The gate driver circuit can also be called GOA (GateDriverOnArray, array substrate row driver) circuit, which uses the array process of the thin film transistor display to fabricate the gate row scan drive signal circuit on the array substrate to realize the drive of the gate row by row scan. way of a technology. [0003] As a shift register, each GOA unit transmits the scan signal to the next GOA unit in turn, turns on the thin film transistor switch row by row, and completes the input of the data signal of the pixel. In the related art, due to the inherent characteristics of...
