Abstract

An embodiment of the invention provides a shifting register unit and a driving method thereof, a grid driving circuit and a display apparatus and relates to the display technology field. A problem that a signal input terminal is in a floating state in a touch control phase for a long time so that a pull-up node potential can not be pulled up to a high level quasi bit can be solved. The shifting register unit comprises a voltage stabilization module, a pull-up control module, a pull-up module, a pull-down control module, a pull-down module and a reset module, wherein the voltage stabilization module outputs a signal of a first control signal terminal to the pull-up control module or pulls down a potential of a signal input terminal to the first control signal terminal; the pull-up control module outputs a signal of a third control signal terminal to a pull-up node; the pull-up module outputs a signal of a first clock signal terminal to a signal output terminal; the pull-down control module outputs a signal of a second clock signal terminal to a pull-down node or pulls down a potential of the pull-down node to a first voltage terminal; the pull-down module pulls down the potentials of the pull-up node and the signal output terminal to a first voltage terminal; and the reset module outputs a signal of a fourth control signal terminal to the pull-up node.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, a gate driving circuit and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) or OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is provided with an array substrate, wherein, the array substrate can be divided into display area and display area peripheral wiring area. Wherein the peripheral area is provided with a gate drive circuit for progressively scanning the gate lines. Existing gate drive circuits often use GOA (GateDriver on Array, array substrate row drive) design to integrate TFT (Thin Film Transistor, Thin Film Field Effect Transistor) gate switch circuits in the above peripheral area to form gate drive circuits. [0003] In addition, with the continuous development of touch (Touch) technology, the ...
