Abstract:
1. A method for driving a liquid crystal display device which uses a liquid crystal as a pixel, said method comprising the steps of: (i) the step of displaying an image by supplying an output signal for an image display period to a the pixel of the liquid crystal display device so as to control luminance of the pixel, the output signal corresponding to a video signal indicative of an image to be displayed by the liquid crystal display device, the step (i) being performed repeatedly; and (ii) the step, performed between the steps (i), of controlling blanking by supplying an output signal for a blanking period to the pixel so that luminance of the pixel does not exceed luminance of the pixel in at least one of the steps (i) between which the step (ii) is performed or so that luminance of the pixel becomes a luminance for dark display, in the step (ii), when a change from first luminance to second luminance is a predetermined one where the first and second luminances are luminances indicated by output signals for image display periods in the steps (i) before and after the step (ii), the output signal for a blanking period being corrected so that the output signal for a blanking period has luminance which is corrected in a same direction as a direction of the change from the first luminance to the second luminance, the direction being a direction in which the luminance increases or decreases compared with an output signal for a blanking period obtained in a case where the first luminance is identical with the second luminance.
