Abstract
In one embodiment, a projection screen includes a diffuse reflecting polarizer that diffusively reflects light polarized in a first direction and transmits light polarized in a second direction. The projection screen may also include a second polarizer adjacent a back side of the diffuse reflecting polarizer, wherein the second polarizer is oriented to transmit light polarized in the second direction. The projection screen may appear substantially diffuse when viewed from a front side and substantially transparent when viewed from a back side.
