Abstract

A fluorescent display suitable for use in a heads up display contains a laminated glass structure containing a plasticized polyvinyl acetal film, at least one fluorophore, and at least one UV absorber, wherein the fluorophore and UV absorber are and remain spatially separated in the laminating film such that UV light projected from a display generating projector remains able to activate the fluorophores, and a UV component of sunlight has lessened ability to activate the fluorophore.
