Abstract
A method of driving a light emitting device in which a plurality of pixels having a light emitting element are formed, characterized by including: setting j display periods (where j is a natural number) to appear in one frame period, each of the j display periods corresponding to one bit of a k-bit digital video signal (where k is a natural number); and subjecting lower n bits of the k bits (where n is a natural number, j.gtoreq.k-n) to one or both of dither processing and error diffusion processing to thereby select whether the pixels turn on or turn off in each of the j display periods according to a (k-n)-bit digital video signal that is converted from the k-bit digital video signal.
