Abstract

The embodiment of the invention provides a shift register and a driving method thereof, a grid driving circuit and a display device, relates to the technical field of display, and can solve the problem of unstable output caused by insufficient potential of a pull-down node in the shift register. The shift register comprises a pull-up node, a pull-down node and a pull-down coupling sub-circuit, Thepull-down coupling sub-circuit is connected with the pull-down node, the first scanning end and the second scanning end; And the pull-down coupling sub-circuit is configured to perform coupling lifting on the voltage of the pull-down node under the control of signals of the first scanning end and the second scanning end.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register, a driving method thereof, a gate driving circuit, and a display device. Background technique [0002] GOA (Gate Driver on Array, array substrate row drive) is a technology that integrates the gate driver circuit on the array substrate, wherein the GOA circuit includes multi-stage cascaded shift registers, and each stage of the shift register is connected to the array substrate. A row of gate lines is connected to output a gate scanning signal to the gate lines, so as to realize progressive scanning (driving) of a plurality of gate lines in the display panel. Contents of the invention [0003] Embodiments of the present invention provide a shift register and its driving method, a gate driving circuit, and a display device, which can solve the problem of unstable output in the shift register caused by insufficient pull-down node potential. [0004] In ...
