  • Patent number: 11092735
    Abstract: A backlight module is provided, including a light guide plate, an optical film, and a light source module. The optical film is disposed on the light guide plate and has an accommodating space. The light source module has at least one light-emitting surface, which can be divided into a light-emitting area and a frame area. The light-emitting area faces the light guide plate, and at least a portion of the frame area enters the accommodating space.
    Type: Grant

  • Patent number: 10473843
    Abstract: A backlight module includes a light source, a light guide plate and a light-adjusting member. A light source chromaticity is measured from light generated by the light source. The light guide plate has a light-incident surface and a light-emitting surface. Light generated by the light source enters the light guide plate and emits out from the light-emitting surface. With the light-adjusting member, a first light guide plate chromaticity is measured from the light-emitting surface. There is a first difference value between the first light guide plate chromaticity and the light source chromaticity. Without the light-adjusting member, a second light guide plate chromaticity is measured from the light-emitting surface. There is a second difference value between the second light guide plate chromaticity and the light source chromaticity. The first difference value is different from the second difference value.

  • 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.

  • Publication number: 20060164863
    Abstract: A light guide plate that can uniformly scatter lights emitted from point light sources is provided. The light guide plate has a light exiting side, a reflection side opposite to the light exiting side, and a light entering side. On the light entering side, there are multiple miniature diffusing entities. Each of the diffusing entities has a curved surface and two slant surfaces extending from the two ends of the curved surface to the light entering side. The curved surface causes the lights from the light sources to undergo multiple-angled refractions. The two slant surfaces cause the lights from the light sources to undergo fixed-angled refraction in both left and right directions. As such, the lights emitted form the light sources could have wider incident angles and could be uniformly scattered into the light guide plate.
