Abstract
A woven projection screen includes a viewing portion having a front side facing toward a viewing zone. The viewing portion includes a plurality of first filaments having asymmetric geometries in cross-section and having reflective surfaces for primarily reflecting an image signal light and a plurality of second filaments. The plurality of first filaments are interwoven with the plurality of second filaments, such that, the plurality of second filaments are configured to support the plurality of first filaments in a manner that causes the reflective surfaces to be positioned to redirect the image signal light into a range of angles toward the viewing zone.
