Abstract:
1. A liquid crystal panel driving apparatus which sequentially receives, at intervals, pieces of video data each corresponding to one data signal line, wherein: the pieces of video data are divided into groups to each of which a predetermined number of pieces of video data belong and in each of which a piece of dummy data is added in a predetermined position; a signal potential corresponding to the piece of dummy data is outputted during a dummy scanning period; a signal potential corresponding to each of the predetermined number of pieces of video data is outputted during one horizontal scanning period; each of the intervals consists of a first horizontal display period and a first horizontal blanking period; the one horizontal scanning period consists of a second horizontal display period and a second horizontal blanking period; and (i) a number of dots of the second horizontal display period is set to be identical to a number of dots of the first horizontal display period and (ii) a number of dots of the second horizontal blanking period is set to be less than a number of dots of the first horizontal blanking period so that the one horizontal scanning period is shorter than each of the intervals.
