Abstract
A glazing unit includes a transparent display located in only one portion of the glazing unit, at least one light-guiding substrate located nearer the exterior than the display, at least one light source located on the periphery of the substrate, for example facing an edge face of the light-guiding substrate, and a light extraction device for extracting the light emitted by the light source. The light source may be formed from a plurality of light emitting diodes.
Claims22
A glazing unit comprising an interior face and an opposed, exterior face:
- a transparent display located in only one portion of an area of the glazing unit, such that at least one other transparent portion of the area of the glazing unit in a plane parallel to the transparent display comprises no portion of the transparent display and the at least one other transparent portion of the area of the glazing unit is configured to allow light to pass from the exterior face to the interior face of the glazing unit, the transparent display comprising an image-producing system configured to display digital format images;
- at least one light-guiding substrate located nearer the exterior face than said transparent display;
- at least one light source located on a periphery of said light-guiding substrate;
- and
- a light scattering structure configured and arranged to scatter the light emitted by the light source through the interior face of the glazing unit.
A glazing unit of a transportation vehicle, the glazing unit comprising:
- an external face to face an exterior of the transportation vehicle and an internal face to face an interior of the transportation vehicle;
- a transparent display located in only one portion of an area of the glazing unit such that at least one other transparent portion of the area of the glazing unit in a plane parallel to the transparent display comprises no portion of the transparent display and the at least one other transparent portion of the area of the glazing unit is configured to allow light to pass from the external face to the internal face of the glazing unit, the display comprising an image-producing system configured to display digital format images;
- a light-guiding substrate located nearer the exterior of the transportation vehicle than the transparent display;
- a light source located on a periphery of said light-guiding substrate, and
- a light extraction device to extract light emitted by the light source.
