Abstract:
According to an aspect, a display device includes: a first liquid crystal panel; a second liquid crystal panel; a light source configured to emit light; and a controller configured to control the first liquid crystal panel and the second liquid crystal panel based on an image signal corresponding to a resolution of the second liquid crystal panel. The first liquid crystal panel includes dimming pixels, and the second liquid crystal panel includes pixels. More than one of the pixels is arranged within a region of each of the dimming pixels. The controller performs blurring processing and determination of dimming gradation values as processing related to operation of the second liquid crystal panel. Each of the dimming gradation values corresponds to a highest gradation value set after the blurring processing among gradation values set for the more than one pixel arranged within the region of each of the dimming pixels.
