Abstract

The embodiments of the invention provide shift registers, a drive method thereof, gate driver on array circuits, a display panel and a display device and relates to the technical field of display. Theproblem that display is abnormal due to the fact that a high level potential of a pull-down node is too low can be solved. A shift register comprises a pull-up node and the pull-down node. The shiftregister also comprises a pull-down compensation sub-circuit. The pull-down compensation sub-circuit is connected with the pull-down node and a high level voltage end. The pull-down compensation sub-circuit is configured to output a high level of the high level voltage end to the pull-down node under the control of the high level of the pull-down node.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register and its driving method, a gate driving circuit, a display panel, and a display device. Background technique [0002] GOA (Gate Driver on Array, array substrate row drive) is a technology that integrates the gate drive circuit on the array substrate, in which each stage of the GOA circuit (that is, the shift register) is connected to a row of gate lines. The gate scan signal is output to the gate line to realize the progressive scanning of the multiple gate lines in the display panel. [0003] Among them, for each stage of shift register in the GOA circuit, it generally includes a plurality of transistors, capacitors, etc., and the potentials of the pull-up node (PU) and the pull-down node (PD) are controlled through the transistors and capacitors, so that the shift register However, due to the channel resistance of the transistor itself and the influenc...
