Kind Code:
B2
Abstract:
Provided is a display device capable of switching a refresh rate while suppressing deterioration in display quality and degradation in liquid crystal. In the case of switching the refresh rate from 60 Hz to 7.5 Hz, a transition period for gradually changing the refresh rate from 60 Hz to 7.5 Hz is provided between a 60-Hz period and a 7.5-Hz period. This transition period is configured by sequentially arraying a 30-Hz period, a 20-Hz period, a 15-Hz period, a 12-Hz period and a 10-Hz period from a start point of the transition period. Hence the refresh rate gradually changes from 60 Hz to 7.5 Hz sequentially through 30 Hz, 20 Hz, 15 Hz, 12 Hz and 10 Hz. The number of positive-polarity frames and the number of negative-polarity frames are respectively 20 in the whole of the transition period, and are equal to each other.
