Abstract
A front projection screen is provided having a first portion of material and a second portion of material. The first and second portions of material may have an undercut edge profile, and the first and second portions of material may be perforated, such that the perforations allow the first and second portions of material to be at least somewhat acoustically transmissive while substantially maintaining optical efficiency from the front side of the front projection screen. Such optical efficiency has particular utility in stereoscopic projection applications utilizing polarized encoded light.
