DISPLAY AND DISPLAY CONTROL CIRCUIT

摘要

A display control circuit of a display performs generation of overdrive processed data and detection of a proper direction of overdriving from current frame uncompressed compressed data obtained by performing compression processing and uncompression processing on compressed data corresponding to image data of a current frame, and previous frame uncompressed compressed data obtained by performing the compression processing and the uncompression processing on image data of a previous frame, and generates post-correction overdrive processed data by correcting the overdrive processed data according to the detected proper direction. The display control circuit transmits post-correction compressed data obtained by compressing the post-correction overdrive processed data to a driver as transfer compressed data.
