Document Type and Number:
WIPO Patent Application WO/2020/220812
Kind Code:
A1
Abstract:
A shift register circuit and a driving method therefor, a gate driving circuit, and a display device. The shift register circuit (100) comprises: an input circuit (110) which is connected to an input end, a first clock end, a first reference voltage end, a first node and a second node and configured to control, in response to a first clock signal from the first clock end, turning on and turning off of the input end and the first node and turning on and turning off of a first reference voltage end and the second node, and control, in response to a potential of the first node, turning on and turning off of the first clock end and the second node ; a first control circuit (120) connected to the first node, the input end, a second clock end, the first reference voltage end and a third node, and configured to control turning on and turning off of the first node and the third node in response to an input signal from the input end and a second clock signal from the second clock end; a second control circuit (130) electrically connected to the second node, the second clock end, a second reference voltage end and the first node, and configured to control turning on and turning off of the second reference voltage end and the first node in response to the potential of the second node and the second clock signal; a third control circuit (140) connected to the first node, the second node, the second reference voltage end, the second clock end, and a fourth node, and configured to control turning on and turning off of the second reference voltage end and the fourth node in response to the potential of the first node, and control turning on and turning off of the second clock end and the fourth node in response to the potential of the second node and the second clock signal; and an output circuit (150) which is connected to the second reference voltage end, the third node, the fourth node and an output end, and configured to control, in response to the potential of the third node, turning on and turning off of the first reference voltage end and the output end, and control, in response to the potential of the fourth node, turning on and turning off of the second reference voltage end and the output end.
