Abstract
Provided is a display control device capable of coping with high-resolution display readily in terms of conducting data write and read on a frame buffer memory in time for the timing of display. The display control device has a plurality of line buffers, and is arranged so that a writing process for writing, into part of the line buffers, display lines of display data from outside, and a reading process for reading out written display lines of display data from other line buffers can be conducted in parallel. In the display control device, display-line data read out from the line buffers are compressed and stored in the frame buffer memory. The compression-display data read out from the frame buffer memory are read out for each line, and decompressed into display lines of display data. The decompressed display data are used to drive signal electrodes of a display device.
