SHIFT REGISTER, GATE DRIVING CIRCUIT, AND DISPLAY PANEL

WIPO Patent Application WO/2021/258888

A1

A shift register, a gate driving circuit, and a display panel. In the shift register, a forward input module (1) is used for providing a signal of a forward power supply voltage end (VNN) to a first node (PU) by means of a first transistor (M1) and a second transistor (M2) in sequence under the control of a forward input end; a reverse input module (2) is used for providing a signal of a reverse power supply voltage end (VBB) to the first node (PU) by means of a third transistor (M3) and a fourth transistor (M4) in sequence under the control of a reverse input end; an output module (4) is used for providing a signal of a clock signal end (CLK) to an output end under the control of the first node (PU), or providing a signal of a first reference signal end (VGL) to the output end under the control of a second node (PD); a node control module (3) is used for controlling potentials of the first node (PU) and the second node (PD) to be opposite; and a leakage prevention module (5) is used for transmitting the signal of the first reference signal end (VGL) to the position between the first transistor (M1) and the second transistor (M2) and the position between the third transistor (M3) and the fourth transistor (M4) respectively under the control of the clock signal end (CLK).
