Abstract

In order to enhance the brightness level of viewing, reflective screens having gain have been developed. These screens require a concave shaping which generally requires a fixed structure that cannot be easily moved or stored. The screen shown in the diagram achieves that concave shape but does so by making use of a plastic air pillow with a reflective screen surface on the inside of the back of the pillow. Thus, this screen can be easily rolled or folded for storage and movement.
