ABSTRACT:
A thin-film multilayer system for use in a head-up display is provided, which comprises: A substrate; a plurality of dielectric layers having a high refractive index sequentially formed on the substrate; and a plurality of dielectric layers having a low refractive index formed alternately with the plurality of dielectric layers having a high refractive index. The thickness and ingredient of each of the plurality of dielectric layers having a high refractive index and the plurality of dielectric layers having a low refractive index are determined according to interference theory for all-dielectric thin-film multilayers to make the thin-film multilayer system able to polarize light and to display images in true color. Further, the ingredients of the thin-film multilayer system are dielectric materials that can endure wear and tear, chemicals, and environmental injuries. The thin-film multilayer system can be directly formed on the windshield of a vehicle, otherwise it can be formed on a substrate made of glass or plastic, and then adhered to the windshield.
