    摘要: 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≧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.

    摘要: There is provided an electronic device in which the deterioration of the device is prevented and an aperture ratio is improved without using a black mask and without increasing the number of masks. In the electronic device, a first electrode (113) is disposed on another layer different from the layer on which a gate wiring (145) is disposed as a gate electrode, and a semiconductor layer of a pixel switching TFT is superimposed on the gate wiring (145) so as to be shielded from a light. Thus, the deterioration of the TFT is suppressed, and a high aperture ratio is realized.
