    摘要: A display panel driver includes a color reducing circuit and a driving section. The driving section is configured to drive a first pixel and a second pixel. If a second input image data and a third input image data corresponding to the second pixel are supplied as an image data of a second image display format, then the color reducing circuit generates a third color reduction image data and a fourth color reduction image data. If the first input image data is supplied as the image data of the first image display format, then the first selector selects the third error value, and if the second input image data and the third input image data are supplied as the image data of the second image display format, then the first selector selects the second error value.

    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.
