  • Publication number: 20100309685
    Abstract: Optical assembly comprises a light emitting panel member having opposite sides and an input edge for receiving light from light sources optically coupled to a different location along the input edge. On or in at least one of the sides of the panel member is a pattern of individual optical deformities that are varied throughout the pattern and shaped or oriented throughout the pattern to extract light propagating through the panel member in different directions for viewing from different angles through one of the sides of the panel member.

  • Patent number: 7819558
    Abstract: Light emitting assembly includes at least one film, sheet, plate or substrate positioned between a light source and a display for redirecting at least some of the light emitted by the light source. One side of the film, sheet, plate or substrate may have a pattern of reflective or refractive surfaces or deformities and the other side may have corresponding or aligned optical deformities of well defined shape. Light emitted from the light source that strikes a reflective or refractive surface or deformity on the one side of the film, sheet, plate or substrate passes through the film, sheet, plate or substrate and is redirected by at least one corresponding optical deformity on the other side of the film, sheet, plate or substrate.

  • Patent number: 7810982
    Abstract: Optical assembly includes a light source adjacent a light input edge and generally parallel and planar first and second surfaces each comprising respective patterns of well defined optical elements that are quite small in relation to the length and width of the optical assembly. At least some of the optical elements of each pattern include a respective sloped surface for directing at least some light emitted from the light source. The respective slope angle of the sloped surface of at least some of the optical elements of one of the patterns is different from the respective slope angle of the sloped surface of at least some of the optical elements of the other pattern such that more of the light is emitted from one of the surfaces than is emitted from the other surface.

  • Publication number: 20100172151
    Abstract: Light emitting assembly includes an optical conductor having a pattern of deformities on or in front and back sides of the optical conductor to cause light to be emitted from a light emitting surface on at least one of the sides. At least one of the deformities varies, and at least one planar or curved refractive surface is aligned with at least one light source to redirect a portion of the light from the light source entering the optical conductor in a predetermined manner to cause the light emitted from the light emitting surface to pass through an optical film, which redirects the light through a liquid crystal display with low loss.

  • Patent number: 7712932
    Abstract: The light redirecting films have a thin optically transparent substrate having a light entrance surface and an opposite light exit surface, at least one of the surfaces including a pattern of individual optical elements of well defined shape having two differently curved surfaces.

  • Patent number: 7703967
    Abstract: Light emitting assemblies include at least one light source, an optical film with deformities, an optical conductor, and at least one light input surface for receiving light from the light source. The optical conductor has a pattern of deformities on or in the front and back sides to cause light to be emitted from at least one light emitting surface on one of the sides. At least one planar or curved refractive surface on a transition area between the light source and the light emitting surface or on the light input surface aligned with the light source redirects a portion of the light entering the optical conductor to pass through the optical film. A tray may also be provided that holds the optical conductor and light source.

  • Publication number: 20100026703
    Abstract: Images are displayed in response to a video signal using a light emitting assembly having one or more optically transmissive substrates, films or sheets, each having at least one pattern of optical elements on or in the substrates, films or sheets. A plurality of light sources are configured to illuminate one or more output areas of one or more of the substrates, films or sheets. The light emitting assembly is configured to emit light through the pattern of optical elements and produce a predetermined luminance profile of the light emitting assembly. At least one of the light sources is dimmed or boosted in response to an input video signal while operating a liquid crystal display as a light valve to illuminate the liquid crystal display by the light emitting assembly.

  • Publication number: 20090257244
    Abstract: Light emitting panel assembly includes a panel member, at least one light source and a light transition member located between the light source and the light input surface of the panel member. On or in the light transition member are elements that effect a desired colored or white light output distribution from a light output area of the panel member. The light transition member may comprise a coating or surface treatment on the light input surface that effects the color of light emitted by the light output area. Alternatively a transparent sheet, plate or film attached to or positioned against the light input surface may have a coating, surface treatment or deformities that effect the color of light passing through the sheet, plate or film to obtain a desired colored or white light output distribution from the light output area.

  • Publication number: 20090250829
    Abstract: A method of forming a varying pattern of optical elements on or in at least one side of an optical panel member involves cutting or forming a pattern or patterns of cavities in a cylindrical or curved substrate or in a sleeve or sleeve segment of the substrate that corresponds to a desired pattern and shape of optical elements to be formed on or in the optical member. The substrate or sleeve or sleeve segment containing the desired pattern or patterns of optical element shaped cavities or depositions or mirror copies or inverse copies thereof is used in production tooling or as a master for production tooling to form the corresponding pattern of optical elements on or in at least the one side of the optical panel member.
