  • Back lighting apparatus of liquid crystal display using optical fiber
    Patent number: 6714185
    Abstract: One embodiment of a back lighting apparatus of a liquid crystal display apparatus includes a light source for generating light, a plurality of optical fibers having both ends optically connected with the light source and a part of the optical fibers attached to the back surface of the liquid crystal display panel. Each optical fiber has one or more diffusion lines for scattering light from the light source to a pixel line of the liquid crystal display panel, thereby lighting the entire portion of the back surface of the liquid crystal display panel. The apparatus has a support plate for fixing the optical fibers to the back surface of the liquid crystal display panel, and an optical diffusing unit for optically connecting the light source to the optical fibers. The present invention can improve the resolution of a liquid crystal display apparatus and allow implementation of a 3D image.
