Abstract:
1. A light generating device comprising: a brightness detector receiving a plurality of image data from an exterior source, detecting a plurality of brightness data corresponding to the image data, comparing a plurality of gray scales corresponding to the image data with a reference gray scale, and outputting an enable signal based on the compared result; a dimming signal controller receiving a compensation signal and the brightness data and outputting a first dimming signal corresponding to the brightness data and a second dimming signal obtained by compensating the first dimming signal based on the compensation signal; a light source driver outputting a driving signal in response to either the first dimming signal or the second dimming signal from the dimming signal controller; a light source section comprising a plurality of light sources that generates a white light in response to the driving signal; and a light source compensator starting its operation in response to the enable signal, receiving the white light from the light source section, and outputting the compensation signal to compensate a light characteristic of the white light.
