A driving method of a display panel, comprising: dividing pixels on the display panel into pairs of pixel sets, wherein each pair of pixel sets comprises a first pixel set and a second pixel set; acquiring a first voltage signal and a second voltage signal according to a frame input signal look-up-table, wherein a front viewing-angle mixed brightness of the subpixel driven by the first and second voltage signals alternately is equivalent to a front viewing-angle brightness of the subpixel driven by a frame input signal; driving first subpixels of the first and second pixel sets by first and second voltage signals of the first subpixel of the first pixel set, respectively; and driving second subpixels of the first and second pixel sets by second and first voltage signals of the second subpixel of the second pixel set, respectively.
