Embodiment Construction

[0038] exist figure 1 , schematically shows a windshield and device according to the invention:

[0039]The windshield 1 comprises two panes 2 and 9 made of glass. Between the two plates there is a plastic intermediate sheet 3 (for example made of PVB (polyvinyl butyral), plasticized PVC, PU or EVA), or containing for example PET (polyethylene terephthalate). ester) thermoplastic multilayer sheet, a series of layers such as PVB / PET / PVB.

[0040] Before lamination, ie before assembly of the individual pieces, a black coating 6 is deposited on at least the lower edge of the inner surface of the first glass pane 9 .

[0041] Generally, the black coating is a coating that already exists on current glass windows and has, for example, a decorative function or a protective function, especially the function of light protection for the adhesive layer used to cover the heat collecting strips of the heating grid. Regardless of its function, the black coating is generally visible over ...

Abstract

The present invention relates to a laminated windshield consisting of a head-up display device, including an assembly of two transparent sheets of inorganic glass or of a polycarbonate-type PC impact-resistant organic material, connected to each other by an insert of thermoformable material or by a multi-layer sheet incorporating such an insert, said windshield is characterized in that the windshield comprises at least one layer of at least one phosphor material selected to respond to an incident light excitation wave within the ultraviolet or IR range by re-emitting light radiation in the visible range and in that said layer is positioned on the windshield, following the driver's angle of vision, with a layer of opaque material arranged on at least one of the edges of said windshield. The invention also relates to the display device for an image on such a laminated windshield.

Description

technical field [0001] The invention relates to the field of display systems projected onto an at least partially transparent carrier of the windshield type. [0002] In particular, the present invention relates to the field of heads-up display systems known technically in English as Head Up Display or simply HUD. Such systems are particularly useful in aircraft cockpits, trains and more recently in private motor vehicles (cars, trucks, etc.). Background technique [0003] In such systems, the glazing generally consists of a sandwich structure comprising, at its simplest, two panes of glass. The two glass panes are connected to each other by a thermoformable intermediate sheet, wherein the intermediate sheet most often comprises polyvinyl butyral (PVB) or consists of PVB. [0004] Head-up display systems are known which display information projected onto glass windows, reflected towards the driver or observer. These systems in particular allow relevant information to be p...
