Abstract:
1. A backlight apparatus having a plurality of light source blocks, the backlight apparatus comprising: a luminance detecting unit which detects a luminance of the light source blocks; a control unit which successively executes a detecting process for each of the plurality of light source blocks by controlling the plurality of light source blocks to turn on one by one, and determines a correction amount of each light source block on the basis of a luminance value detected by the luminance detecting unit and a target value thereof; and a temperature fluctuation suppressing unit which executes a temperature fluctuation suppressing process after the control unit executed the detecting process for a light source block as a detecting objective, and before the control unit executes the detecting process for another light source block as next detecting objective during the entire process of executing detecting processes for all of the light source blocks of the backlight apparatus, wherein, in the temperature fluctuation suppressing process, the temperature fluctuation suppressing unit controls at least one of the plurality of light source blocks to turn on for a predetermined period so that the light source block as the next detecting objective is heated, the at least one of the plurality of light source blocks including the light source block as the next detecting objective.
