Title:
DISPLAY APPARATUS, GATE ELECTRODE DRIVER CIRCUIT, SHIFT REGISTER CIRCUIT AND DRIVE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/063314
Kind Code:
A1
Abstract:
A display apparatus, a gate electrode driver circuit, a shift register circuit and a drive method thereof, the shift register circuit comprising an input sub-circuit connected to a first node of the shift register circuit, configured so as to receive a first control signal, and causing a potential of the first node to jump from a starting potential to a first potential according to the first control signal, the first potential being greater than the starting potential; an output sub-circuit connected to the first node of the shift register circuit, configured so as to receive a first clock signal, generating an output signal according to the first clock signal and the potential of the first node and causing the potential of the first node to jump from the first potential to a third potential, the third potential being greater than the first potential; a shading sub-circuit connected to the first node of the shift register circuit, configured so as to receive a second control signal, causing the potential of the first node to gradually decrease from the third potential to a fourth potential according to the second control signal, causing a potential of the output signal to gradually decrease, and causing the potential of the first node to jump from the fourth level to the starting potential according to a third control signal, the fourth potential being greater than the starting potential and less than the third potential.
