  • Patent number: 7948581
    Abstract: In a liquid crystal display equipped with a side edge backlight device, visualization of “a dot provided to a light guide plate” in the vicinity of the light source while keeping the luminance of the display screen. The shapes and the arrangement of the light diffusing dots (dots) provided to the principal surface of the light guide plate of the backlight device are made different between the area of the principal surface in the vicinity of the light source and the other areas, thereby adjusting the whiteness of the light guide plate in the vicinity of the light source. The plurality of dots formed in the vicinity of the light source are each composed of a first section for diffusing the light propagating the light guide plate, and a second section surrounded by the first section and less capable of diffusing the light, and are disposed in the vicinity of the light source in a zigzag manner.

  • Patent number: 7710515
    Abstract: In order to solve the problem that sufficient center brightness is not always obtained in a conventional liquid crystal TV and a liquid crystal monitor, a backlight module of the invention includes a plurality of cold cathode fluorescent lamps (CFL) and a diffusing reflector below, the distance between the respective CFLs is arranged so that a central portion is narrow and an end portion is wide, and the backlight module includes a triangular sectional projection structure on at the diffusing reflector only between the CFLs between which the distance is the widest, in the end portion. According to the invention, enhancement of the center brightness without increasing consumption power, reduction in the number of CFLs, and cost reduction accompanying it are achieved.
