1. A driving method of a display panel, comprising:
acquiring display data, having grayscale values corresponding to subpixels emitting light having at least two colors, of a frame;
calculating a typical grayscale value, representing a total grayscale level of subpixels emitting light having each of the at least two colors, corresponding to the subpixels emitting light having each of the at least two colors according to the display data; and
determining a common supply voltage corresponding to the subpixels emitting light having each of the at least two colors according to the typical grayscale value;
wherein determining the common supply voltage corresponding to the subpixels emitting light having each of the at least two colors according to the typical grayscale value comprises:
classifying all grayscale values of the subpixels emitting light having each of the at least two colors into a plurality of grayscale levels, and matching a common supply voltage according to the plurality of grayscale levels to obtain a plurality of voltage levels; and
determining, according to a magnitude of the typical grayscale value, a grayscale level to determine a corresponding voltage level, and the typical grayscale value belonging to the grayscale level.
