LIGHT SOURCE MODULE, LIGHT SOURCE SYSTEM, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To maintain superior white light in a light source module suitably utilized for a direct type backlight device in particular.

SOLUTION: The light source module 31 which has a plurality of kinds of LEDs 31b to respectively emit light of RGB and carries out light emission of the white light by mixed color of the respective colors is provided with a light receiving sensor 31c to receive the light emitted from the LEDs 31b and to measure strength of the light, and a color correction circuit 31i to carry out color correction by controlling output of the LEDs 31b based on a light measurement result of the light receiving sensor 31c. The color correction circuit 31i controls the output of the light-out LEDs 31b based on a differential between the light measurement result in a state that all the LEDs 31b are lighted on and the light measurement result in a state that the LED 31b of either kind of RGB is in light-out state.
