ABSTRACT:
An image screen includes a transparent substrate, a metal film, and an optical reflective stack layer. The metal film is disposed on a first surface of the transparent substrate, having a thickness and a set of material characteristic constants being predetermined. The optical reflective stack layer is disposed over the metal layer. The metal film and the optical reflective stack layer function together to selectively reflect a light with a portion of wavelength. In addition, according to the need, a diffusion micro-structure layer can be disposed on a second surface of the transparent substrate. Further for example, another reflective layer or optical absorbing layer can be further disposed on another surface of the optical reflective stack layer. The reflective layer can be, for example, a metal film.
