  • Patent number: 7688402
    Abstract: A backlight module includes a light box and multiple real light sources. The light box has an opening and a plurality of substantially parallel grooves recessed from a bottom surface thereof. Each of the slots has a reflection curved surface. A light source allocation line is defined between every two adjacent grooves. The light source allocation lines are parallel to the grooves. The sum of shortest distances between any point of the reflection curved surface and the two adjacent light source allocation lines is substantially the same. In addition, the real light sources are alternately allocated in the light source allocation lines. A part of light emitted from each light source is reflected from the reflection curved surface to the light source allocation line in which no light source is allocated. Thereby, a virtual light source is formed on the light source allocation line that does not contain a real light source.

  • Patent number: 7316496
    Abstract: A planar light source device includes a substrate, a circuit layer and light sources. The substrate is penetrable to visible light and has a radiating surface and a second surface opposite the radiating surface. The circuit layer and the light sources are disposed on the second surface of the substrate, and the light sources are electrically connected to the circuit layer.

  • Patent number: 7264373
    Abstract: A backlight module (BLM) including a bezel, at least a first lamp and at least a second lamp is provided. The bezel has a first lighe region and is arranged substantially in parallel to the top side of the bezel. The second lamp is positioned in the second light source region and is arranged substantially in parallel to the top side of the bezel. The second lamp corresponds to the first lamp.

  • Patent number: 7220044
    Abstract: A liquid crystal display and backlight module. The backlight module comprises a base plate, first reflectors, light sources, second reflectors, diffuser plate and diffuser film. Each first reflector comprises a wave-shaped structure and is provided with a first reflecting surface facing toward the base plate and a focus. Each light source is disposed at the focus of the first reflector and the light beams from the light source reflected by the first reflector pass through the base plate toward the diffusive film in parallel. Each second reflector is disposed on the base plate and provides with a second reflecting surface faced toward the light source. Thus, mura phenomenon and interferences between the two adjacent light sources can be reduced.
