Kind Code:
A1
Abstract:
A shift register, a gate driving circuit, and a display device. The shift register comprises: an input circuit (1) configured to control, in response to signal control provided by a first clock signal end (CK), a signal provided by a signal input end (INPUT) to a third node (N3); a first control circuit (2) configured to write, in response to a signal provided by a preset control signal end (CS) and signal control provided by a second clock signal end (CKB), a voltage provided by a first power supply end into a first node (N1); a second control circuit (3) configured to write, in response to signal control provided by the signal input end (INPUT), a voltage provided by a second power supply end to the first node (N1); and an output circuit (4) configured to write, in response to the control of a voltage at the first node (N1), the voltage provided by the second power supply end to a signal output end (OUT), and write, in response to the control of a voltage at the fourth node (N4), the voltage provided by the first power supply end to the signal output end (OUT), the third node (N3) being coupled to the fourth node (N4).
