Abstract
The viewing angle brightness sensitivity typically encountered in tiled rear projection display systems cannot be solely overcome by edge blending and calibration techniques. The rear projection array display-screen system of this invention, being comprised of a micro-structure array screen combined with a conventional diffusion screen, overcomes this viewing angle brightness sensitivity in both linear as well as matrix tiled rear projection display systems including those that use wide field-of-view projectors. The latter capability enables low form-factor and compact packaging of tiled rear projection display systems.
