Abstract

The invention provides a shifting register unit, a gate drive circuit and a display device, which are used for suppressing interfering noise caused by the change of alternating-current clock signals and improving the stability of the shifting register unit. The shifting register unit comprises an input module for responding to an input signal and charging a pull-up node, a pull-down module for responding to a voltage signal of a pull-down node and providing a low voltage signal for the pull-up node and an output terminal, a pull-down driving module for responding to a voltage signal of the pull-up node and discharging to the pull-down node, an output module for responding the voltage signal of the pull-up node and providing a first clock signal for the output terminal, and a reset module for responding to a second clock signal and discharging to the output terminal.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a shift register unit, a gate drive circuit and a display device. Background technique [0002] The thin film transistor liquid crystal display (TFT-LCD) driver mainly includes a gate drive circuit and a data drive circuit. The pole driving circuit may be formed in the same process as the TFTs and simultaneously formed on the LCD panel together with the TFTs. The gate driving circuit includes a shift register unit having multiple stages, and each stage is connected to a corresponding gate line to output a gate driving signal. The stages of the gate drive circuit are connected to each other, the start signal is input to the first stage of each stage and the gate drive signal is sequentially output to the gate line, wherein the input terminal of the current stage is connected to the output terminal of the previous stage , and the output terminal of the next stage i...
