A display device driver and a control method thereof are provided to restore images in small capacity memories by compressing data based on a correlation between preceding and following data. A sub-pixel renderer(10) constitutes 1/2 RGB data in consideration of peripheral RGB information of basic input RGB data. A data compressor(20) receives output from the sub-pixel renderer and stores redundant portions of the data in a compression format by using a correlation between preceding and following data. A memory(30) stores output from the data compressor. A data restorer(40) restores the data from the memory. A source driver latch unit(50) outputs the data from the data restorer.
