    Abstract: A display may be based on a display unit that is mounted within a chassis. The display unit may be a liquid crystal display unit. A backlight may be used to illuminate the display unit. The backlight may include a light guide plate. Light from a light source may be launched into an edge of the light guide plate. Scattered light from the light guide plate may travel vertically along a vertical axis that is perpendicular to the plane that contains the light guide plate. The scattered light may pass through the display unit and may serve as backlight for the display. The light guide plate may be mounted within a rectangular opening in the chassis. The edges of the rectangular opening and the edges of the light guide plate may be configured to reduce excessive reflections. These edges may have reflection-reducing coatings, non-planar surfaces, and other reflection-reducing configurations.

  • Patent number: 8102494
    Abstract: An anti-reflection film that can provide high visibility and has an anti-reflection function by which reflection of incident light from external can be further reduced, and a display device having such an anti-reflection film. A plurality of contiguous pyramidal projections is arranged in a geometric pattern, so that reflection of incident light is prevented. In addition, a protective layer formed of a material having a lower refractive index than the pyramidal projections is provided so as to fill a space between the plurality of pyramidal projections. The plurality of pyramidal projections has a hexagonal shape and can be densely arranged with no space therebetween. Further, since six sides of each pyramidal projection are provided at a different angle from the base, light can be effectively scattered in many directions.

  • Patent number: 8088475
    Abstract: A conventional thin membrane of aerogel, although achieving a low refractive index, retains some difficulty when it is to be applied to display apparatuses or the like, because of its low strength. Membranes produced by other methods are difficult to simultaneously achieve low refractive index and sufficient strength. The present invention provides an anti-reflecting membrane which is formed at least on one side of a plate transmitting visible light, is composed of fine inorganic oxide particles and a binder, contains a number of pores inside, and has an arithmetic average surface roughness (Ra) below 6 nm. The present invention also provides preferred embodiments of the display apparatuses provided with the membrane.

  • Patent number: 8049824
    Abstract: A single-layer birefringent crystal trim retarder includes a birefringent crystal cut such that its optic axis is at a high oblique angle and such that it provides low in-plane retardance values even when the birefringent crystal is relatively thick. To compensate for the inherent high +C-plate retardance of this high-tilt O-plate, the single-layer birefringent crystal is coupled with a ?C-plate thin-film retarder to provide a trim retarder having an overall A/?C-plate retarder functionality. This full-function trim retarder is practical to fabricate, is thickness and azimuthal angle tolerant, and is suitable for low sensitivity angular clocking requirements of LCoS panel compensation.
