Title: SHIFT REGISTER UNIT, DRIVE METHOD THEREFOR, GATE DRIVE CIRCUIT, AND DISPLAY APPARATUS
Abstract:
A shift register unit, a drive method therefor, a gate drive circuit, and a display apparatus, comprising: a shift register (10) and a potential stabilisation module (20), the potential stabilisation module (20) being used for respectively supplying the signal of a reference signal terminal (VSS) to a pull-up node (PU) and a drive signal output terminal (Output) under the control of a potential stabilisation control terminal (VT); thus, by means of the coordination of the shift register (10) and the potential stabilisation module (20), the signal of a reference signal terminal (VSS) can be supplied respectively to the pull-up node (PU) and the drive signal output terminal (Output) during a discharge holding phase after a reset phase, in order to keep the potential of the pull-up node (PU) and the potential of the drive signal output terminal (Output) in a stable state, and thereby being able to prevent the scanning signal outputted by the drive signal output terminal (Output) from having large noise, improving the stability of the output of the shift register unit.
