LIGHT SOURCE DEVICE AND DISPLAY DEVICE

摘要

The purpose of the present invention is to enable light having a desired light intensity to be outputted in a broad brightness range spanning from low to high brightness, even if light intensity characteristics of light sources have been changed. Light sources emit inspection light of a fixed output and image light of an output based on an image signal. A light-branching unit branches the light from the light sources. A light detection unit detects the light intensity of reflected light branched by the light-branching unit. A signal conversion unit converts a first detection signal from the light detection unit, and outputs the resultant signal as a third detection signal. A main control unit inputs the third detection signal, and controls the output of the image light on the basis of the third detection signal. A refresh unit refreshes the third detection signal inputted to the main control unit.

1. A light source device comprising:
a light source capable of emitting at least image light having output power that is based on an image signal; a light branching unit branching light from the light source; a light detection unit detecting a light intensity of the light branched by the light branching unit; a signal conversion unit converting a detection signal from the light detection unit and outputting the converted signal; a control unit controlling output power of the image light based on the input converted signal; and a refresh unit refreshing the converted signal input to the control unit.
