Abstract

Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness uniformity and contrast for both 2D and 3D systems. Generally the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate thus creating engineered particles from the optically functional material. The engineered particles may then be deposited on a second substrate to create a substantially homogeneous optical appearance of the projection screen.
