Illumination device and display device including the same
First Claim
1. An illumination device comprising:
- a light source in which a plurality of light emitting elements are arranged;
a luminous intensity controller configured to control luminous intensities of the plurality of light emitting elements separately in groups of one or more light emitting elements; and
a predetermined correction table indicating temperature distribution characteristics corresponding to position information of the plurality of light emitting elements in the light source, whereinthe luminous intensity controller controls the luminous intensities of the plurality of light emitting elements corresponding to the position information in accordance with the temperature distribution characteristics of the correction table, andthe luminous intensity controller controls the luminous intensities of the plurality of light emitting elements based on temperature differences between temperature settings at positions corresponding to the plurality of light emitting elements in the temperature distribution characteristics of the correction table, and a reference temperature which is used as a reference for a luminous intensity control of controlling the luminous intensity.
