  • LED LIGHT ENGINE FOR BACKLIGHTING A LIQUID CRYSTAL DISPLAY
    Publication number: 20060256555
    Abstract: An edge-lit backlighting system for liquid crystal displays employs a number of light strips in the form of thin, light weight sections of a thermally conductive substrate each of which mounts a plurality of light engines having an array of densely packed, primary color light emitting diodes, which, when collectively illuminated, produce a white light of desired reference white chromaticity.
    Type: Application
