A vehicle glazing and display system includes a vehicle compound glazing unit including a layer or surface which diffusely reflects incident light directed to the glazing unit from the interior of the vehicle and having a maximum gain in the range of 0.1 to 0.8 and a viewing angle for a real image element generated within the glazing plane of more than 60°, in a first direction and of more than 30°, in a second direction, perpendicular to the first direction, and a projector for projecting an image to the vehicle glazing unit to generate a real image in the plane of the glazing unit and wherein the vehicle compound glazing unit is a windshield.

An article used as black or dark-colored front-projection screen includes two distinct diffusely reflecting scattering elements, taking the form of parallel sheets or planes, qualified first and second scattering elements, wherein the first scattering element is translucent or transparent and the second scattering element is of dark color.

Dark-coloured or black projection screen

A method for obtaining a glass plate marked on a portion of one of its faces with code-forming symbols, includes a stage of etching the symbols by laser radiation on a glass sheet obtained by floating on a bath of molten tin, the etching being carried out on the face which has been in contact with the bath of molten tin.

A transparent layered element includes two transparent external layers having substantially the same refractive index and each having a smooth external main surface, and a central layer intermediate between the external layers, the central layer including at least one transparent layer of refractive index different from that of the external layers or a metal layer. All the contact surfaces between two adjacent layers of the layered element, one of the two layers of which is a metal layer, or that are two transparent layers of different refractive indices, being textured and parallel to one another, the diffuse light reflection of the layered element on the side of at least one of the external layers having at least one maximum in a direction different from the direction of specular reflection. In addition, the surface of the layered element is divided into a plurality of pixels of same size.

A layered element includes two transparent outer layers having approximately the same refractive index and each having a smooth outer main surface, the layered element including a screen zone with properties of diffuse reflection and specular transmission comprising a textured middle layer interposed between the outer layers, a peripheral zone with properties of specular reflection and specular transmission, and a transition zone with properties of diffuse reflection and specular transmission between the screen zone and the peripheral zone, which includes a textured middle layer interposed between the outer layers. The diffuse light reflection at any point of the transition zone is less than or equal to the diffuse light reflection at any point of the screen zone and the variation of the diffuse light reflection in the transition zone from the screen zone to the peripheral zone, in any direction joining the screen zone to the peripheral zone, is decreasing.
