Abstract : Screens used for viewing projected images have been analyzed to consider the effect on brightness as a function of viewing angle caused by making the screen directional in its reflective properties. In each case the screen is compared to a matte-white surface. This surface has the property of brightness being a constant at all viewing angles. Three screens are considered: a beaded screen and two hypothetical screens. The beaded screen is the most directional screen commercially available. (Author)
