ABSTRACT:
Driving condition is determined so that the stimulating values of brightness with respect to drive data become closer to being regular in interval. As the drive condition, the frequency of a reference clock used for the pulse width modulation is changed to be higher than the range of high gradations in the range of low gradations in drive data. Accordingly, smaller increment in brightness in the range of low gradation and larger increment in the range of high gradations are achieved.
