Patent ID: 8294695

Claim:
A display driving apparatus, comprising: a memory unit, for storing a previous compressed frame; a compression and decompression unit, for receiving a current frame and the previous compressed frame, compressing the current frame to obtain a current compressed frame, and decompressing the current compressed frame to obtain a current decompressed frame, and decompressing the previous compressed frame to obtain a previous decompressed frame; a data selection unit, obtaining a frame state information according to the current decompressed frame and the previous decompressed frame, and determining a compression error according to the current frame and the current decompressed frame, wherein when the compression error is smaller than a predetermined value and the frame state information is dynamic, the data selection unit outputs the previous decompressed frame as a first frame, otherwise, when the compression error is greater than the predetermined value or the frame state information is static, the data selection unit outputs the current frame as the first frame; and a display accelerating unit, determining an overdrive value according to the first frame and a second frame.
