Title:
SHIFT REGISTER, GATE DRIVE CIRCUIT, DISPLAY DEVICE AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/157862
Kind Code:
A1
Abstract:
A shift register (200, 400, 1000), a gate drive circuit, a display device and a driving method (2000), the shift register (200, 400, 1000) comprising: a first input sub-circuit (210, 410), which is configured to receive a first input signal from a first input end (STU1) and output a blanking output control signal; a second input sub-circuit (220, 420), which is configured to receive a second input signal from a second input end (STU2) and output a display output control signal; a selection sub-circuit (230, 430), a first end of the selection sub-circuit (230, 430) being connected to the second input sub-circuit (220, 420), a second end of the selection sub-circuit (230, 430) being connected to the first input sub-circuit (210, 410), and a third end of the selection sub-circuit (230, 430) being connected to a first node (Q); the selection sub-circuit (230, 430) is configured to control the potential of the first node (Q) according to the display output control signal and the blanking output control signal; and an output sub-circuit (240, 440), which is configured to output a composite output signal by means of an output end (OUT) under the control of the first node (Q).
