Title:
SHIFT REGISTER UNIT, GATE DRIVE CIRCUIT, DISPLAY DEVICE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/134413
Kind Code:
A1
Abstract:
A shift register unit (300, 400, 500, 600, 700, 900), a gate drive circuit, a display device, and a control method (1200) for the display device. The shift register unit (300, 400, 500, 600, 700, 900) comprises an input sub-circuit (310, 510, 710), an output sub-circuit (320, 520, 720), and a shutdown control sub-circuit (330, 530, 730). A first end of the input sub-circuit (310, 510, 710) is connected to a first signal line (Vdd); a second end of the input sub-circuit (310, 510, 710) is connected to a pull-up node (PU); a third end of the input sub-circuit (310, 510, 710) is connected to an input signal line (Output n-1); a first end of the output sub-circuit (320, 520, 720) is connected to the pull-up node (PU); a second end of the output sub-circuit (320, 520, 720) is connected to a clock signal line (CLK); a third end of the output sub-circuit (320, 520, 720) is connected to an output end (Output n) and is configured to be controlled by the pull-up node (PU) to output a clock signal inputted by the clock signal line (CLK) to the output end (Output n); a first end of the shutdown control sub-circuit (330, 530, 730) is connected to the output end (Output n); a second end of the shutdown control sub-circuit (330, 530, 730) is connected to a first shutdown control signal line (SHUTDOWN 1); a third end of the shutdown control sub-circuit (330, 530, 730) is connected to a second shutdown control signal line (SHUTDOWN 2), wherein the shutdown control sub-circuit (330, 530, 730) is configured to be controlled by a first shutdown control signal to output a second shutdown control signal inputted by the second shutdown control signal line (SHUTDOWN 2) to the output end (Output n).
