Document Type and Number:
WIPO Patent Application WO/2019/085578
Kind Code:
A1
Abstract:
Provided are a shift register and a drive method therefor, a gate drive circuit, and a display apparatus. The shift register comprises a first input sub-circuit for outputting, under the control of a first signal input terminal, a voltage of a first control voltage terminal to a pull-up node; n output sub-circuits for sequentially outputting, under the control of the pull-up node, signals of an output clock signal terminal to various signal output terminals; a first pull-down control sub-circuit for outputting, under the control of a first clock signal terminal, a voltage of a first control voltage terminal to a pull-down node; a second pull-down control sub-circuit for pulling down, under the control of the pull-up node, a voltage of the pull-down node to a first voltage; and a pull-down sub-circuit for pulling down, under the control of the pull-down node, a voltage of the pull-up node to the first voltage.
