Abstract:
1. A display control device comprising: a display data interface which is supplied with display data from outside; a plurality of line buffers serving as buffer regions, and arranged so that a writing process for writing each display line of display data output from the display data interface into part of the buffer regions, and a reading process for reading out display lines of display data written therein from other parts of the buffer regions can be conducted in parallel; a compressing part for compressing display-line data read out from the line buffers; a frame buffer memory for storing compression-display data subjected to compression by the compressing part; a decompressing part for reading out compression-display data from the frame buffer memory for each line, and decompressing the compression-display data into display lines of display data; and a driving part for outputting driving voltages for driving signal electrodes of a display device by use of decompressed display data.
