Abstract:
A method of driving an electrophoretic display device includes changing the gradation level of image data on the basis of correction data corresponding to the gradation level, converting image data with the changed gradation level to a dithering pattern, in which the first color and the second color are combined, corresponding to the changed gradation level for each predetermined region of image data, and driving the electrophoretic particles of the first color and the electrophoretic particles of the second color on the basis of image data converted to the dithering pattern for the plurality of pixels in the display section.
