Abstract
A reflective projection screen comprising multiple horizontal row segments facilitates directing a reflected image to provide a wide horizontal viewing angle within a relatively narrow vertical viewing band. Each horizontal row segment has a surface that distributes incident light over a wide horizontal angle. The vertical inclination of each row segment is varied from the top to the bottom of the screen to direct the light vertically.
