SHIFT REGISTER AND DRIVING METHOD THEREFOR, GATE DRIVING CIRCUIT, AND DISPLAY DEVICE

WIPO Patent Application WO/2020/224422

A1

A shift register, comprising an input sub-circuit (100). The input sub-circuit (100) is coupled to a signal input terminal (Iput). The input sub-circuit (100) comprises a first input control unit (101) and a boosting unit (102). The first input control unit (101) is coupled to a first clock signal terminal (CLK1), a first node (A), a second node (B), and a pull-up node (PU); and the first node (A) is configured to receive an input signal (input) transmitted by the signal input terminal (Iput). The boosting unit (102) is coupled between the first node (A) and the second node (B). The first input control unit (101) is configured to: under the control of the voltage of the first node (A), transmit a first clock signal (clk1) received at the first clock signal terminal (CLK1) to the pull-up node (PU) via the second node (B). The boosting unit (102) is configured to: under the action of the first clock signal (clk1), when the potential of the second node (B) rises, raise the voltage of the first node (A), so that the voltage loss of the first clock signal (clk1) in the process of being transmitted from the first input control unit (101) to the pull-up node (PU) is reduced.
