MICRO-STRUCTURE BASED SCREEN SYSTEM FOR USE IN REAR PROJECTION ARRAY DISPLY SYSTEMS

摘要

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 (200) of this invention, being comprised of a micro-structure array screen (210) combined with a conventional diffusion screen (205), 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.
