  • White light source for LCD backlight
    Patent number: 6655825
    Abstract: A white light is provided for backlighting a liquid crystal display by directing red green and blue light into the first end of a color mixing optical fiber, mixing the red green and blue light in the color mixing fiber to produce white light, and conducting the white light out of the second end of the color mixing fiber to the liquid crystal display. The color mixing optical fiber and sources for generating the red green and blue light may be located remotely from the liquid crystal display, and the white light produced in the color mixing optical fiber coupled to the liquid crystal display by coupling optical fibers, thus simplifying and facilitating construction and operation of the backlighting system, and allowing for more convenient removal of heat remotely from the liquid crystal display.
