Grid driving circuit, restoration method thereof, display panel and display device

摘要: The invention discloses a grid driving circuit, restoration method thereof, display panel and device, wherein the is used for improving capacity of circuit. circuit comprises M levels sub-circuits, an Nth-level sub-circuit. Each level sub-circuit shift register scanning control at least sub-circuits corresponding to sub-circuits. providing signal (N+1)th-level according output when works abnormally in forward (N-1)th-level reverse scanning, N=2,3,4......M-2, M-1, positive integer equal or larger than four.
