(57) [Summary] [PROBLEMS] For a display panel such as a liquid crystal used for a portable type, Although the number of display colors has been reduced due to power saving, a display system with higher image quality (multicolor display) and power saving has been demanded. A controller performs an error diffusion process or a dither process, and performs a spatial color reduction process on multicolor original image data. After the processing, the data is transferred to the internal memory of the segment driver IC 14. The segment driver 14 reads data from the built-in memory and displays an image. |
