Abstract: The present invention discloses a structure for storing overdrive image data and a method thereof, which divide image data into non-video data and video data and respectively store them in a non-video data storage region and a video data storage region of a memory unit, wherein the RGB data of the non-video data is directly stored in the video data storage region; the RGB data of the video data is transformed into YCbCr data; via checking a lookup table, the RGB data of the present video data is compared with the RGB data of the preceding frame to obtain overdrive YCbCr data; the YCbCr data and the overdrive YCbCr data are sampled, compressed and synthesized according to a video data compression standard and then stored in the video data storage region. Thereby, the memory space required by the overdrive technology can be reduced.

Abstract: An access structure for an internal memory of driving control elements includes a transformation and compression module to transform three primary color signals of graphic data to YCbCr signals and compress the YCbCr signals, thereby to reduce storage requirement so that a given internal memory in a driving control element can store bigger or more image and graphic data, a memory module to store the compressed YCbCr signals and a decompression transformation module to read and decompress the compressed YCbCr signals, and transform the YCbCr signals to three primary color signals to output image data.
