Abstract

The embodiment of the invention discloses a shift register unit and a driving method thereof, a gate driving circuit and a display device. The shift register unit includes: an input circuit configuredto output an input signal from an input signal terminal to the pull-up node; an output circuit configured to output a clock signal from a clock signal end to an output signal end under the potentialcontrol of the pull-up node; a reset noise reduction circuit configured to perform reset and noise reduction on the pull-up node and the output signal end under the control of the potential of the pull-down node; and a pull-down node control circuit connected to the first voltage end and the pull-down node, and configured to electrically connect the pull-down node with the first voltage end underthe potential control of the pull-down node.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to a shift register unit and a driving method thereof, a gate driving circuit and a display device. Background technique [0002] In a liquid crystal display (Liquid Crystal Device, LCD) based on a thin film transistor (Thin Film Transistor, TFT), a gate drive circuit for driving a gate may be formed on a display panel to constitute a Gated Drive On Array (GOA) panel. The gate drive circuit may include a plurality of cascaded shift register cells. In a traditional gate drive circuit, the output signal of the next-stage shift register unit is usually used as the reset signal of the current-stage shift register unit, and the output signal of the upper-stage shift register unit is used as the current-stage shift register unit input signal. [0003] However, especially when the area of ​​the display panel is large, the output signal of the shift register unit will have waveform distor...
