An embodiment of the invention relates to the technical field of display, in particular to a driving method, an array substrate, a display panel and a display device used for improving uneven brightness at junctions of independent common electrode blocks. A gate drive unit sequentially outputs gate drive signals to gate lines according to Hs, effective level time of the gate drive signals is T, wherein (N+1)*THs>T>N*THs, T-N*THs>3delta, and delta>/=R*C. Since T-N*THs>3delta, at the end of effective level in the gate drive signals received by the other gate lines in the adjacent gate lines except for the last gate lines, the voltage difference between a pixel electrode and the common electrode block corresponding to the last gate line in the adjacent gate lines reaches the stable state; therefore, uneven brightness at the junctions of the independent common electrode blocks is improved, and further stripes are generated on a display screen.
