  • Light generating module, liquid crystal display device having the same, and method of improving color reproducibility thereof
    Patent number: 8159143
    Abstract: A light generating module includes a light emitting part and a power supplying part. The light emitting part includes a first region and a second region. First and second lights having different wavelengths from each other are generated in each of the first and second regions. The first region is an outermost region of the light emitting part. The power supplying part applies different currents to the first region from the second region to generate the first and second lights having different intensities from each other. Therefore, color uniformity is increased so that an image display quality is improved.
