Abstract:
1. An electro-optical device comprising: a plurality of pixels arranged in association with intersections of a plurality of scanning lines and a plurality of data lines, each of the plurality of pixels displaying a grayscale level corresponding to a data signal supplied to a corresponding data line when a scanning line is selected; a memory that stores upper n bits of input image data in which the grayscale level of each of the plurality of pixels is designated by m bits and that reads the stored n bits of image data, where “m” and “n” represent positive integers satisfying a condition m>n; an adding circuit that adds lower (m−n) bits to the n bits of image data read from the memory; a selector that selects the input image data when the m bits of image data are input and that selects image data including the (m−n) bits added thereto by the adding circuit when the n bits of image data are read from the memory; a scanning line driving circuit that selects, from among the plurality of scanning lines, the scanning line corresponding to the image data selected by the selector; and a data line driving circuit that supplies the data signal based on the image data selected by the selector to the data line corresponding to the selected image data.
