A driving method of a display panel is described. A display panel including a pixel array is provided. The pixel array includes N scan lines, M data lines, and a plurality of first pixel units and a plurality of second pixel units electrically connected to the scan lines and the data lines. When an image is displayed with a wide-viewing angle mode, a first scanning procedure is performed to sequentially scan the first scan line of the scan lines to the Nth scan line of the scan lines in order. When the image is displayed with a narrow-viewing angle mode, the second scanning procedure is performed to sequentially scan the Nth scan line of the scan lines to the first scan line of the scan lines in order.
