HIGH-BRIGHTNESS DIRECTIONAL VIEWING SCREEN

摘要

A high-brightness directional viewing screen (10) having an output directed toward a predefined viewing area (12) and providing high brightness is disclosed. The viewing screen has a micro-sculpted surface relief structure therein which increases brightness in a predefined viewing area by controlling the direction in which light propagates from the screen. The screen works either in reflection or transmission in a wide variety of viewing situations such as viewing slides, television, overhead transparencies, liquid crystal displays, microscope projection screens, and many others.
