The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by printing the obscuration on a film laminated between at least two layers of plastic interlayers or directly on the interlayer rather than printing and firing an enamel frit onto the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.

The present invention proposes an optical device according to claim 1. The optical device comprises a glazing with a top outer surface and a bottom outer surface extending between a first lateral end face and a second lateral end face. The glazing comprises at least one outer layer made of glass or of an optically clear polymer material. The glazing comprises a photoluminescent structure having one or more photoluminescent domains. The optical device comprises a light source for injecting excitation light into said glazing, said excitation light being suitable to excite the one or more photoluminescent domains to induce photoluminescence of the one or more photoluminescent domains. The light source is optically coupled to the glazing to inject light such that the light injected at the first lateral end face of the glazing so that the light is guided to propagate through the glazing from the first lateral end face to the second lateral end face, the glazing forming a waveguide between the top surface and the bottom surface by total internal reflection of the light at the top outer surface and the bottom outer surface, to induce photoluminescence of the one or more photoluminescent domains.

A glass laminate structure is disclosed with a first and a second glass ply and a printed polymer ply interposed between the first and second glass plies, the printed polymer ply may be of PVB or PET having nanoparticle-containing ink adhered to at least a portion of a surface. Optionally there may be at least one further polymer ply which may be of PVB, PVA, COP or TPU. The nanoparticle-containing ink may contain electrically conductive nanoparticles, especially silver nanoparticle-containing ink. Also disclosed is a process for producing such a glass laminate structure.

Disclosed is a multi-layer screen protector for a display of an electronic device. The screen protector may include a glass exterior surface for tactile response, an optically clear anti-explosion adhesive to contain broken glass from the protector or the display, and a TPU layer to provide impact resistance. The screen protector may be flat or curved.
