    摘要: According to an aspect of the invention, a light guide is provided which includes a light guide substrate having a top surface through which light is to be emitted, a bottom surface, an incident edge surface through which incident light is to be introduced into the light guide substrate, and another edge surface. The another edge surface includes at least one micro structure operative to reflect at least a portion of the incident light, which travels through the light guide substrate and is incident on the another edge surface, back within the light guide substrate.

    摘要: A display is provided having private and public viewing modes. The display comprises a display device and a parallax optic (3) comprising an array of parallax elements (4). Each of the elements (4) co-operates with a set of pixels (1,2) having at least one first pixel (1) and at least one second pixel (2). A line (23) passing through the centre (21) of each first pixel (1) and the centre (22) of the cooperating parallax element (4) extends into a first viewing region (20a). The parallax elements (4) re-strict viewing of the first pixels (1) to the first viewing region and permit viewing of the second pixels (2) in a second viewing region. The display device displays a private image in the private viewing mode by means of only the first pixels (1) and displays a non-private image in the public viewing mode by means of at least the second pixels (2).

    摘要: A display comprises: a single-view image display panel (6); and a parallax optic (8) disposed over a display face of the image display panel for restricting the angular spread of light output from the display face of the image display panel. This enables light to be concentrated in a desired viewing angle range (66), and avoids a user (56) seeing unwanted reflections that may occur as a result of a greater viewing angle range (64) if the parallax optic (8) is not provided. The display may be used, as an example, in a motor vehicle to prevent unwanted reflections from the windscreen (62) of the vehicle.

    摘要: A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. The light extracted from the lightguide has an angular emission profile such that when incident on a prism film, collimated light is produced.

    摘要: A display comprises: a transmissive pixellated spatial light modulator (21); and a backlight (22). The backlight has a light-transmissive waveguide (26), with a first face of the waveguide being opposed to the spatial light modulator (21). The first face of the waveguide comprises a plurality of regions that are not totally internally reflective for at least one polarisation of light propagating within the waveguide, and the remainder of the first face of the waveguide is totally internally reflective for light propagating within the waveguide. Light is extracted from the waveguide at the regions where first face of the waveguide is not totally internally reflective. The pitch of the regions where first face of the waveguide is not totally internally reflective is substantially an integer multiple of the pitch of the pixels of the spatial light modulator.
