A driving method of display panel includes: dividing pixels with same one color on the display panel into sets of pixel pairs, each set including a first subpixel and a second subpixel; displaying each frame using two frame images in order; obtaining a first voltage signal and a second voltage signal, a positive-viewing-angle mixed brightness of the subpixel being equivalent to a positive-viewing-angle brightness of the subpixel; driving the first subpixel of the first frame image by the first voltage signal of the first or second subpixel, and driving the second subpixel by the second voltage signal of the first or second subpixel; and driving the first subpixel of the second frame image by the second voltage signal of the first or second subpixel, and driving the second subpixel of the second frame image by the first voltage signal of the first or second subpixel.
