1. A transparent screen comprising:

  • a first enclosure;

    a first polarizer retardation film with half wave mirror;

    a first diffusion surface, or diffractive surface or element;

    a first optical grade plastic with Cold Cathode Florescent Lamp (CCFL) or Light Emitting Diodes (LEDs) surrounding the circumference of the optical grade plastic;

    a second diffusion surface;

    a first transflective film;

    a LCD panel;

    a second transflective film;

    a third diffusion surface;

    a second optical grade plastic with Cold Cathode Florescent Lamp (CCFL) or Light Emitting Diodes (LEDs) surrounding the circumference of the optical grade plastic;

    a fourth diffusion surface, or diffractive surface or element;

    a second polarizer retardation film with half wave mirror, and a second enclosure. wherein the first polarizer retardation film is positioned between the first enclosure and the first diffusion surface;

    the first diffusion surface is positioned between the first polarizer retardation film and the first optical grade plastic;

    the first optical grade plastic is positioned between the first diffusion surface and the second diffusion surface;
