Document Type and Number:
WIPO Patent Application WO/2019/076124
Kind Code:
A1
Abstract:
A gate drive circuit (40) and a drive method therefor, and a display device (90). The gate drive circuit (40) comprises shift registers (41) of N grades which are in cascade connection, wherein N is an integer that is greater than or equal to 4. Among the shift registers (41) of N grades, the signal output end (OUTPUT) of the nth grade shift register (41) is connected to the signal input end (INPUT) of the (n+I/2)th grade shift register (41); and the reset signal end (RESET) of the nth grade shift register (41) is connected to the signal output end (OUTPUT) of the (n+K)th grade shift register (41), wherein n is an integer that is greater or equal to 1 and is less than (N-I/2), K is an integer that is greater than I/2 and less than I, and I is the number of clock signal lines connected on the gate drive circuit (40) and is an even number greater than or equal to 4.
