Compressed data transmission in panel display system

Abstract:

A host device divides original data into first to N.sup.th stream data for N being an integer of two or more, generates first to N.sup.th compressed stream data by sequentially compressing the first to N.sup.th stream data with a variable length compression, divides the first to N.sup.th compressed stream data into fixed-length blocks, and sequentially transmits the fixed-length blocks to the display driver. The display driver includes a memory storing therein the fixed-length blocks and a decompression circuitry reading out the fixed-length blocks from the memory. The decompression circuitry includes first to N.sup.th processing circuits. The first to N.sup.th processing circuits each perform a predetermined process on the fixed-length blocks received to generate processed data. The host device sorts the fixed-length blocks so that the fixed-length blocks are supplied in the order in which the first to N.sup.th processing circuits require the fixed-length blocks.
