Document Type and Number:
WIPO Patent Application WO/2021/227766
Kind Code:
A1
Abstract:
A shift register unit and a control method therefor, and a gate drive circuit and a display apparatus. The shift register unit comprises: a first control circuit (110) and an energy storage circuit (150), which directly control the potential of a first node (Q1); a pull-down control circuit (120), a second control circuit (130) and a first pull-down circuit (140), which indirectly control the potential of the first node (Q1); and an output circuit (160), which outputs, under the control of the potential of the first node (Q1), a first voltage signal provided by a first voltage end (VDD) to a signal output end. By means of the shift register unit, the control method therefor and the gate drive circuit, the pulse width of a gate scanning signal can be adjusted, thereby meeting various display requirements.
