    摘要: A backlight module and an illumination device thereof. The illumination device of the backlight module comprises a light source and a lens, disposed over the light source with a predetermined gap therebetween. The lens comprises a bottom surface as an incident surface, a pair of upper refracting surfaces, and a pair of lateral refracting surfaces. The upper refracting surfaces form an included angle substantially in a range of about 80° to about 120°.

    摘要: A light guide plate structure, for use with a back light module of a liquid crystal display, has a top surface, a bottom surface, a first end portion, a second end portion which is opposite the first end portion, and a plurality of substantially paralleled V-shape grooves formed on the bottom surface and extending from the first end portion to the second end portion. Each of said V-shape grooves comprises a top angle with a continuous variation from the first end portion to the second end portion. The present invention gets rid of the dark areas of an LCD that appear adjacent to one of the end portions in conventional models, thus enhancing the uniformity in its brightness levels.

    摘要: A backlight module is provided. The backlight module includes a light guide plate, a lamp and an optical microstructure. The light guide plate has an edge side. The lamp is disposed on the edge side of the light guide plate. The lamp has an electrode end. The light guide plate has a corner shadow area adjacent to the corner shadow area. Light generated by the lamp propagates toward the edge side in the first direction. The optical microstructure is disposed on a surface of the edge side of the light guide plate and guides the light toward the second direction to enter the corner shadow area.

    摘要: A light guide plate has a substrate and a set of curved grooves. The set of curved grooves are on the substrate, and has a plurality of curves parallel to the substrate. By the curved grooves, the light guide plate can mitigate the Moiré effect induced by the conventional light guide plate and increase the intensity of emitting light.
