Patent ID: 7050035

Claim:
A drive circuit for an electro-optical device, including a display portion having pixels arranged in a matrix and having a light transmittance ratio changed by applying voltage, supplying on-voltage to make the light transmittance ratio be saturated, or off-voltage to make the light transmittance ratio be a non-transmissive state to the display portion, and implementing sub field drive to realize gray-scale display in response to a ratio of an optical transmissive state to a non-transmissive state of the electro-optical material per unit time, comprising: a first pixel driving device, driving each of the pixels with each sub field as a unit of control that is formed by dividing a field into plural portions on a time axis, and driving one of the pixels located at a predetermined position in an image by a first sub field drive pattern that is an arranged pattern of a sub field of applying the off-voltage and a sub field of applying the on-voltage; a second pixel driving device, driving the pixel with each sub field as a unit of control that is formed by dividing a field into plural portions on a time axis, and driving another of pixels adjacent to the pixel located at the predetermined position in an image by an least one second sub field drive pattern differentiated from the first sub field drive pattern; and a timing of starting a field to supply the on-voltage or the off-voltage to the pixel is shifted regarding each adjacent pixel.
