ABSTRACT:
A compressive overdrive circuit includes: a compression unit for compressing a current frame to generate compressed data for buffering, where the compressed data comprises pixel values of a plurality of non-encoded pixels and a plurality of index values associated with the non-encoded pixels; and a decompression unit for decompressing according to the pixel values of the non-encoded pixels and the index values to generate data of a previous frame. The overdrive circuit performs overdrive processing according to the current frame and the previous frame.
