Patent ID: 10546549

Abstract:
The present invention provides a shift register unit and its driving method, a gate drive circuit and a display device, which can at least partially alleviate the problem of noise interference caused by non-release of the coupling capacitance of the thin film transistor itself in the GOA circuit. The shift register unit comprises: a pull-up control module for transmitting voltage of a first voltage terminal to a pull-up control node under the control of a first signal input terminal; a reset module for pulling down the potential of said pull-up control node to a voltage of a second voltage terminal under the control of a second signal input terminal; an output module for transmitting a signal input through a first clock signal terminal to a signal output terminal under the control of said pull-up control node; a first control module for pulling down the potential of the signal output terminal to the voltage of the second voltage terminal under the control of a second clock signal terminal; a second control module for pulling up or down the potential of the pull-up control node to a voltage of the first signal input terminal under the control of the second clock signal terminal.
