ABSTRACT:
A display driving apparatus and method using a display device, such as a liquid crystal display device, and a medium for implementing a method of display driving method are provided. The display driving apparatus includes: an encoding unit which compresses and encodes image data to be displayed by the display device; a memory which stores the encoded image data; a memory control unit which stores the encoded image data in the memory and reads the encoded image data from the memory; and a decoding unit which decodes the encoded image data read out from the memory to restore the image data. Input image data is compressed and encoded in units of blocks, and the encoded image data is stored in a memory. Thereafter, the encoded image data stored in the memory is decoded, and the decoded result is output to a display device. Thus, it is possible to reduce the size of a memory included in a display driving apparatus without deteriorating the quality of an image displayed.
