Patent ID: 7106351

Claim:
A method of driving an electro-optical device having a memory, which is provided in each of a plurality of pixels, to store gradation data, the electro-optical device dividing a predetermined period of time into a first subfield group and a second subfield group and performing gradational display with a combination of subfields corresponding to first data forming some of the gradation data and second data being different from the first data and forming some of the gradation data, the method of driving an electro-optical device comprising: first writing the first data in a memory provided in each of the pixels; second reading the first data written in the memory and applying a voltage corresponding to the first read data to the pixels based on a first gradation signal defining each of the subfields forming the first subfield group; third writing the second data in the memory; and fourth repeatedly reading the second data written in the memory a plurality of times and repeatedly applying a voltage corresponding to the second read data to the pixels a plurality of times based on a second gradation signal defining each of the subfields forming the second subfield group.
