    摘要: Disclosed is a backlight control apparatus for controlling a backlight used in a liquid crystal display, the backlight having a lighting area that includes a plurality of blocks in each of which a backlight luminance is individually allowed to change. The apparatus includes a backlight control unit that calculates the backlight luminance of each block so that the absolute value of the difference between a backlight lighting ratio and 1 is at or below a first value, and controls the backlight so as to yield the calculated backlight luminances of the respective blocks, the backlight lighting ratio being the ratio between backlight set values of neighboring blocks.

    摘要: A surface light source device which illuminates a transmission-type liquid crystal display unit from the back surface includes P×Q surface light source units with individually controlled light sources. Each of the light sources includes a plurality of light-emitting element units. Each of the light-emitting element units includes at least one red light-emitting element that emits red light, at least one green light-emitting element that emits green light, and at least one blue light-emitting element that emits blue light. The center of mass of a luminance profile based on each of a plurality of red light-emitting elements, a plurality of green light-emitting elements, and a plurality of blue light-emitting elements in each surface light source unit substantially coincides with the center of mass of the surface light source unit.
