Title:
SHIFT REGISTER, GATE DRIVING CIRCUIT AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/178868
Kind Code:
A1
Abstract:
A shift register, comprising: an input circuit (1), configured to, in response to signal control provided by a first clock signal end (CK), write into a third node (N3) a signal provided by a signal input end (INPUT); a first control circuit (2), configured to, in response to a signal provided by a preset control signal end (CS) and signal control provided by a preset clock signal end, write into a first node (N1) a voltage provided by a first power supply end; a second control circuit (3), configured to, in response to signal control provided by the signal input end (INPUT), write into the first node (N1) a voltage provided by a second power supply end; an output circuit (4), configured to, in response to control of the voltage at the first node (N1), write into a signal output end (OUT) the voltage provided by the second power supply end, and in response to control of the voltage at a fourth node (N4), write into the signal output end (OUT) the voltage provided by the first power supply end, the third node (N3) being coupled to the fourth node (N4).
