  • Light guide plate having light diffusing entities on light entering side
    Patent number: 7347610
    Abstract: A light guide plate has a light exiting side, a reflection side opposite to the light exiting side, and a light entering side. A plurality of miniature diffusing entities, each having a curved surface and two slant surfaces extending from the two ends of the curved surface, are formed on the light entering side. The combination of the curved surface and the two slant surfaces cause light emitted from point-like light sources to have wider incident angles and be uniformly scattered into the light guide plate.
