Abstract. This paper describes a projection system using DLP projectors and parabolic mirrors to provide a 90° curved screen with a 4-to-1 aspect ratio. This display is intended to provide an 'immersive' experience for the user and facilitate a very large canvas on which to utilize multiple applications or single ones requiring a large screen. The resulting display has a 3072 × 768 pixel display area.

Keywords: Display, projection, lumens, parabola, immersive
