Document Type and Number:
WIPO Patent Application WO/2020/177008
Kind Code:
A1
Abstract:
A shift register (400) and a driving method therefor, and a gate driving circuit. The shift register (400) comprises: an input circuit (410), a reset circuit (420), a first output circuit (430) and a second output circuit (440), wherein the input circuit (410) is configured to provide a first node (PU) with an input signal from an input end (INPUT); the reset circuit (420) is configured to provide the first node (PU) with a first voltage from a first voltage end (V1) under the control of a reset signal from a reset signal end (RESET); the first output circuit (430) is configured to output, based on a first control signal (ctr1), a second control signal (ctr2) and the voltage of the first node (PU), one of a first clock signal (CLK1) and a second clock signal (CLK2) from a first output end (OUT1), and to use same as a first scanning signal; and the second output circuit (440) is configured to output, based on the first control signal (ctr1), the second control signal (ctr2) and the voltage of the first node (PU), another one of the first clock signal (CLK1) and the second clock signal (CLK2) from a second output end (OUT2), and to use same as a second scanning signal.
