BACKLIGHT DEVICE AND BACKLIGHT CONTROL METHOD |
摘要 |
A backlight device includes: a light emitting unit that includes a plurality of light sources having different light emission colors from each other; a detection unit that detects light emission states of the plurality of light sources; a temperature sensor that measures a temperature in a proximity of the plurality of light sources; a brightness conversion unit that converts values indicating the detected light emission states to obtain a detection value for each color of the light emission colors; and a calculation unit that corrects the obtained detection value for each of the light emission colors by using information indicating a relationship between the measured temperature and a correction value, and determines drive values for the light sources based on the corrected detection value. |
