Device for viewing an image on a laminated substrate

摘要

A glazing panel for a display device, includes an external first transparent pane and an internal second transparent pane, each pane including an external face and an internal face, the glass panes being joined together by an interlayer made of a thermoformable material or by a multilayer sheet incorporating such an interlayer; a protective layer made of an opaque material making contact with the internal face of the external first pane; a masking layer made of an opaque material making contact with the internal face of the internal second pane, the masking layer including apertures forming pictograms; and a uniform layer of a material doped with luminescent species chosen because they absorb light radiation produced by the source generating radiation in the UV or IR range, and re-emit light radiation in the visible range, the uniform layer being placed in the glazing panel, between the masking layer and the protective layer.

主权项

1. Glazing panel for a display device, said glazing panel comprising an assembly of at least:
an external first transparent glass pane and an internal second transparent glass pane, each pane comprising an external face and an internal face, said glass panes being joined together by an interlayer made of a thermoformable material or by a multilayer sheet incorporating such an interlayer; a protective layer made of an opaque material making contact with the internal face of the external first pane; a masking layer made of an opaque material making contact with the internal face of the internal second pane, said masking layer comprising apertures forming pictograms; and a uniform layer of a material doped with luminescent species chosen to absorb light radiation produced by a source generating radiation in a ultraviolet (UV) or infrared (IR) range, and to re-emit light radiation in a visible range, said uniform layer being placed in the glazing panel, between said masking layer and said protective layer.
