Abstract
A backlight unit includes a light source having a plurality of light-emitting units that emit light in at least three different colors, a light guide plate having N preset regions, where N is a positive integer, and a backlight control unit controlling the light-emitting units to provide light to the N preset regions. The light guide plate has a light incidence side, and the light source is disposed opposite to the light incidence side. The light emitted by the light source spreads in the preset regions. The backlight control unit acquires image data information corresponding to the preset regions, and derives chrominance and luminance information of the image corresponding to the preset regions, by calculating the acquired image data information. The backlight control unit then, based on the chrominance and luminance information of the preset regions, controls the light-emitting units to provide light to the preset regions.
