Patent ID: 7352375

Claim:
A method of driving a light emitting device in which a plurality of pixels having a light emitting element are formed, the method comprising: setting j display periods (where j is a natural number) 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); subjecting lower n bits of the k bits (where n is a natural number, j≧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; and turning on the pixels that perform display of the q-th gray scale information for at least one display period in addition to all of the turn-on display periods for displaying the (q−1)-th gray scale information (where q is a natural number).
