Claim:
1. A display device comprising: a plurality of pixels including a plurality of sub-pixels respectively corresponding to different colors, and a plurality of source lines; a driver configured to drive the source lines; and a controller configured to compress image data showing the level of the sub-pixel and generate compression data, and supply transfer data including the compression data to the driver, wherein the controller includes: a first sorter circuit configured to perform a first sorting process to sort data included in the image data in at least one of either a time sequence or a spatial sequence; and a compression circuit to perform compression processing on the first sorted image data output from the sorter circuit to generate the compression data, wherein the compression processing performs different processes on the image data of the sub-pixels corresponding to different colors, and wherein the driver includes: a decompression circuit to decompress the compression data included in the transfer data and generate decompression data; a second sorter circuit configured to perform a second sorting process on the decompression data to sort the image data in at least either a time sequence or a spatial sequence to generate second sorted image data; and a display driver circuit configured to drive the source line in response to the second sorted image data, wherein when performing the compression processing on image data corresponding to a plurality of specified pixels, one among the specified pixels includes a dummy sub-pixel not utilized in the display, wherein, when the number of a certain color sub-pixel among sub-pixels included in the specified pixels is fewer than the other color sub-pixels, the first sorter circuit in the first sorting process inserts copied image data copied from the specified sub-pixel image data for any of a certain color sub-pixel into the first sorted image data.
