Abstract

The invention provides a shift register unit, a driving method, a gate driving circuit and a display device. The shift register unit comprises a reset circuit, wherein the reset circuit is connected with a pull-up node and is used for resetting the potential of the pull-up node in a reset phase, and the shift register unit also comprises a reset control circuit; the reset control circuit is connected with the reset circuit and is used for controlling and reducing the leakage current of the reset circuit at an output stage so as to maintain the potential of the pull-up node as a first voltage.The shift register unit circumvents the influence of the leakage current of a reset transistor on the output of a gate driving signal, therefore the display is not influenced.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique

[0002] In the existing narrow bezel display module, there is no light-shielding tape on both sides of the backlight, and the backlight directly illuminates the GOA (Gate On Array, gate driver installed on the array substrate) on both sides of the backlight. The reset transistor in the bit register unit generates carriers due to light, so the leakage current of the reset transistor is large, which will pull down the potential of the pull-up node in the output stage, resulting in the shift register unit not being able to output the gate drive signal stably , so that the gate drive voltage drops, and the module displays abnormally. Contents of the invention

[0003] The main purpose of the present invention is to provide a shift register unit, a driving method, a ...
