Abstract
A rear screen projection apparatus comprises a screen (3), the screen being translucent and extending in a first direction (x) and a second direction (y) perpendicular to the first direction (x) and curved by a constant radius of curvature in a third direction (z) perpendicular to the first and second directions (x, y); a reflector (2), the reflector extending in the first direction (x) and the second direction (y) and being curved by a constant radius of curvature in the third direction (z); and a position (1) for an optical focal point of a projector_ The curvatures of the screen (3) and the reflector (2) may be concentric. The rear screen projection apparatus may have a projector (6) with its optical focal point at the position (1). The reflector (2) may be made of plastic. The position (1) may be in the radial direction of the concentric reflector (2) and screen (3), half way between the reflector (2) and the screen (3).
