Patent ID: 7486262

Claim:
A method of driving an electronic device for performing display of an image using an n-bit digital image signal (where n is a natural number, n≧2), wherein the electronic device has a source signal line driver circuit, a gate signal line driver circuit, and a plurality of pixels, the method comprising: in the source signal line driver circuit, outputting a sampling pulse from a shift register and inputting the sampling pulse to a latch circuit; storing the n-bit digital image signal in the latch circuit in accordance with the sampling pulse; and writing the n-bit stored digital image signal to a source signal line; in the gate signal line driver circuit, outputting a gate signal line selection pulse and selecting a gate signal line; writing a first bit data of the n-bit digital image signal into a first memory provided in one of the pixels; writing a second bit data of the n-bit digital image signal into a second memory provided in the one of the pixels; writing an n-th bit data of the n-bit digital image signal into an n-th memory provided in the one of the pixels; and obtaining a gray scale in the one of the pixels based on the n-bit digital image signal in a frame comprising a first period, a second period, and an n-th period so that the one of the pixels is placed in an ON state in at least one of the first period, the second period, and the n-th period based on the first bit data, the second bit data, and the n-th bit data, respectively, wherein the first period is longer than the second period, and the second period is longer than the n-th period.
