Abstract
A rear projector for projecting an image onto a display screen mounted on a frame. The frame includes first and second pairs of oppositely disposed mounting members having surfaces adapted to contact the screen. Each mounting member of the first pair is formed of first and second inwardly angled portions which meet at a juncture in a middle region of the member. The screen is coupled to the surfaces of the first and second pairs of mounting members to form an inward curvature of the screen.
