Abstract
A windshield includes a windshield body and an ambient display coupled to the windshield body. The ambient display includes a light guide plate and a light source optically coupled to the light source. Aside from the light source, the ambient display includes a transparent phosphor film and an optic array. The transparent phosphor film includes at least one phosphor. The optic array includes a plurality of lenses and is disposed between the light guide plate and the transparent phosphor film. The light guide plate is positioned relative to the optic array such that light emitted from the light source is directed toward the optic array. The chromaticity and luminance of the light emitted by the transparent phosphor film can be adjusted based on the electrical current received by the light source.
