  • Backlight system and liquid crystal display using the same
    Patent number: 7101070
    Abstract: A backlight system (100) in accordance with the present invention includes a plurality of light sources (110) for emitting light beams and a light guide plate (120) for receiving the light beams emitted by the light sources. The light guide plate includes a light input surface (121) and a light output surface (122) joining the light input surface. The light input surface has a plurality of protrusions (124) thereon. The light beams are refracted and diffused by the protrusions, and are then transmitted through the light guide plate to be emitted with a high degree of uniformity through the light output surface.
    Type: Grant

  • Light guide module having uniform light diffusion arrangement and method for making the same
    Patent number: 7039286
    Abstract: A light guide module (10) for use in a flat panel display (21) comprises a light guide pipe (20) having a light emitting surface (21), and a light incident surface (25) orthogonal to the light emitting surface. A light diffusion arrangement (30) is deployed over the light emitting surface and includes organic scattering balls (31) homogenously mixed within a bonding agent (33). At least a light source (60) is arranged adjacent the light incident surface to project light beams into the light guide module.
