Abstract
In a field sequential type liquid crystal display apparatus in which each frame period is configured with first to fourth transparent subframe periods and blue, green, white, and blue subframe periods, a backlight unit is driven as follows. Light sources are in a turn-off state in the transparent subframe periods. In a second half of the blue, green, and red subframe periods, each of blue, green, and red light sources is in a turn-on state. In a second half of a white subframe, all light sources are in the turn-on state. Driving image data that corresponds to such a configuration of the frame period is generated from input image data, and a liquid crystal panel is driven based on the driving image data.
