Projection screen and projection method
First Claim
1. A projection screen defining a horizontal direction and a vertical direction, comprising a panel, said panel having a front and a rear surface, the front surface formed of a plurality of vertically oriented rod segments comprised of parallel surfaces defining pairs of vertically oriented reflective surfaces, the reflective surfaces of each of said pairs forming a plurality of substantially V-shape channels, said rod segments being arranged in a plurality of horizontal rows of predetermined vertical lengths, each said row of said rod segments having a predetermined angle of inclination with respect to a vertical plane.

Abstract
A reflective projection screen has in a first aspect a plurality of reflective elements. The upper surface of the reflective elements is either coated or textured to interfere with reflection of light from the upper surface to an adjacent reflective element. In a second aspect of the invention, a screen is provided that reflects light in the vertical direction like a plane surface, while reflecting light in the horizontal direction back toward the light source. In a third aspect of the invention, a projection system projects a three-dimensional image.
