First Claim
Patent Images
1. A curved-screen rear projection display, comprising:
- a curved translucent display screen;
plural electronic projectors positioned behind the display screen to project respective display images adjacent each other onto the display screen; and
pincushion distortion-compensating optical elements in association with the electronic projectors to compensate for pincushion distortion arising from projection of display images onto the curved display screen, the pincushion distortion-compensating optical elements including curved reflectors positioned in optical paths between the electronic projectors and the curved display screen.

Abstract
The present invention provides an immersive rear projection display capable or providing aspect ratios of 2.66:1 or 4:1, or even greater. This allows viewers to be “immersed” in the images being displayed because the images can encompass both the direct and the peripheral views of a viewer. In one implementation, the immersive rear projection display includes two or more electronic projectors (e.g., three) that are positioned behind a curved translucent display screen. The electronic projectors project respective display images adjacent each other onto the display screen.
