ABSTRACT:
The invention enhances gradation characteristics and realizes higher quality in a picture, in the context of subfield driving using a pixel provided therein with a memory. A method of driving an electro-optical device that divides a predetermined period of time into a plurality of subfields SF5to SF17, performs gradational display with a combination of subfields SF corresponding to gradation data, and provides a memory storing gradation data that is provided in each of a plurality of pixels is disclosed. In the method, at least part of gradation data is written in a memory provided in each of pixels. Further, data written in the memory are repeatedly read several times based on gradation signals defining each of the subfields SF, and a voltage having time density corresponding to read data is repeatedly applied to the pixels to thereby perform gradational display in accordance with gradation data.
