ABSTRACT:
A light generating device includes a brightness detector. The brightness detector extracts a brightness data from an image data. The light generating device compensates the uniformity of a white light whenever the image data that is greater than a reference gray scale is input through the brightness detector. Thus, the light generating device may compensate the uniformity of the white light in real time, so that a display apparatus employing the light generating device may improve a high-quality image.
