Abstract (en)
[origin: WO2023038797A1] A vehicle or other system may have windows. The windows may be formed by laminating together glass layers. The glass layers may include a curved inner glass layer with a convex outer surface and a curved outer glass layer with a concave inner surface. A polymer adhesive film such as a polyvinyl butyral film may be adhered to the convex outer surface. An additional polymer layer formed from a different material than the polymer film may be interposed between the polymer film and the second glass layer. The additional polymer layer may be formed from a gap-filling liquid polymer adhesive layer. The layer of gap-filling liquid polymer adhesive may have a first surface adhered to the polymer film and a second surface adhered to the concave inner surface. An optical layer may be embedded in the additional polymer layer.
