LIGHT SOURCE DEVICE AND METHOD FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of highly accurately adjusting emission luminance at a light emitting part.SOLUTION: A light source device of the present invention includes: a light source substrate where a light emitting part is provided; an optical sheet reflecting light emitted from the light emitting part; two or more detectors detecting reflected light reflected by the optical sheet; and an adjustment means for adjusting the emission luminance at the light emitting part using the two or more detectors. The adjustment means estimates an estimated detection value using detection values of the two or more detectors, the estimated detection value being a detection value of a detector in a case when the detector is provided at a position where a variation of a detection value due to deflection of the optical sheet is equal to or less than a predetermined value, and adjusts the emission luminance at the light emitting part on the basis of the estimated detection value.
