1. A driving method of a display panel, comprising:
initializing gray level states of sub-pixels of the display panel, wherein the gray level states comprise a high gray level and a low gray level;
dividing the sub-pixels of the display panel into N areas, wherein N is a positive integer greater than or equal to 2; and
driving the gray level states of the sub-pixels in the same area to remain for N consecutive frames, and switching the gray level states of the sub-pixels in one of the N areas in the same frame;
wherein the step of the gray level states of the sub-pixels of the display panel comprises:
initializing the gray level states of the sub-pixels to a corresponding high gray level or a corresponding low gray level;
configuring a point value in a gamma curve with a first correction coefficient of less than an average value to be the corresponding high gray level; and
configuring a point value in the gamma curve with a second correction coefficient of greater than or equal to the average value to be the corresponding low gray level, wherein the average value of the first correction coefficient and the second correction coefficient is obtained by dividing a sum of the first correction coefficient and the second correction coefficient by 2.
