Title:
SHIFT REGISTER AND DRIVING METHOD, GATE DRIVING CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/001200
Kind Code:
A1
Abstract:
A shift register and a driving method, a gate driving circuit and a display device. The shift register comprises: an input circuit (100), which is electrically connected to an input voltage terminal (STV) and a first clock signal terminal (CK), respectively, and is configured to input, under the control of a first clock signal provided by the first clock signal terminal (CK), an input voltage provided by the input voltage terminal (STV) to an intermediate circuit (200); the intermediate circuit (200), which is electrically connected to an intermediate output terminal (GOUT), a first power supply terminal (VGH), a second power supply terminal (VGL), the first clock signal terminal (CK) and a second clock signal terminal (CB), respectively, and is configured to write, under the control of the input voltage and a control circuit (300), into the intermediate output terminal (GOUT) a second clock signal outputted by the second clock signal terminal (CB) or a first power signal outputted by the first power supply terminal (VGH) so as to serve as an intermediate output signal; an output circuit (400), which is electrically connected to the first power supply terminal (VGH), the second power supply terminal (VGL), a third power supply terminal (VGL1), a third clock signal terminal (CK1), the intermediate output terminal (GOUT) and an output terminal (EOUT), respectively, and is configured to output an output signal inverted from the intermediate output signal. The shift register can improve the display quality of a display panel.
