Abstract
An information processing system includes a bus, a display data generating circuit coupled to the bus, and a display apparatus coupled to the bus. The display apparatus includes a display panel capable of displaying a grayscale image in accordance with display data in a form of a plurality of bits for each of a plurality of pixels of a display panel generated by the display data generating circuit, and a signal driver which supplies driving voltages corresponding to the display data to at least a part of the plurality of data lines to display a grayscale image on the display panel. The signal driver includes a display memory which stores the display data, and is embodied in an integrated circuit. The display data generating circuit transfers the display data to the display memory via the bus.
