  • Light module for LCD panel
    Patent number: 6871973
    Abstract: A light module with LED light source for LCD panel. Light-receiving surfaces of LGP (light guide plate), light-receiving surfaces of LGS (light guide stick) or light-emitting surfaces of LGS are coated with the mixed fluorescent powder and the white light with triple wavelength is made by the light rays emitted from UV LED to excite the mixed fluorescent powders. It could replace the white light LED with double wavelength of Nichia to reduce the production cost and increase the color performance of LCD.
    Type: Grant
    Filed: November 25, 2002
    Date of Patent: March 29, 2005

  • Light module for LCD panel
    Publication number: 20040100789
    Abstract: The present invention generally relates to an improved light module with LED light source for LCD panel. The edge surfaces of light-receiving and/or light-emitting of LGP and/or LGS are coated with the mixed fluorescent powder layer and the white light with triple wavelength is made by the light rays emitted from UV LED to excite the mixed fluorescent powders. It could replace the white light LED with double wavelength of Nichia to reduce the production cost and increase the color performance of LCD.
