ABSTRACT:
An aircraft passenger entertainment system projects three complementary color component images, preferably from a passenger cabin ceiling, onto a flat screen with the aid of three imaging devices, each of which presents a different color component image in an image display field, and three associated projecting devices including a lens for each imaging device. Each image display field is disposed in a plane which is either parallel to the plane of a flat display screen or which intersects the plane of the display screen along a line extending parallel to the cabin floor of the aircraft. Each of the mentioned projecting lenses has an axis which is either perpendicular to the plane of the display screen or which is disposed in one of three parallel planes extending between the cabin ceiling and floor at right angles to the display screen.
