Abstract
Disclosed is a display driving device, a display device including the same, and an image data compression and decompression method. The display driving device comprises an encoder that compresses PenTile® matrix encoded input image data using a binary encoding scheme and a DPCM encoding scheme, calculates errors produced by each encoding scheme, and selects an encoding scheme mode and its compressed data according to the calculated errors. A decoder decompresses the compressed data according to a decoding scheme corresponding to the selected encoding scheme mode. And a source driver drives source lines connected with a display panel based on decompressed data.
