Abstract
A display driver IC for controlling display of an image on a display panel is provided with a DRAM and a driver circuit. The DRAM has a plurality of memory cells and stores digital data corresponding to the image. The driver circuit converts the digital data into a gray-scale voltage and outputs the gray-scale voltage to the display panel. The DRAM is configured to store one bit data by using n memory cells of the plurality of memory cells, n being an integer of 2 or more.
