  • Patent number: 6814443
    Abstract: The present invention provides a projection system for the display of images in a wide range of ambient light conditions. The system comprises a system control component, two or more projectors and a screen unit. The system control component synchronizes two or more images for projection by the projectors, with the image synchronization enabling the generation of a coherent single image from multiple projected images. There are two or more projectors which project separate images and each projector projects an image onto a unique area of a screen unit. The synchronization of the projectors is also controlled by the system control component. The screen unit has one or more screens for receiving the projected images and these screens are compatible with a rear projection system. The screens incorporate a contrast enhancing component which improves the resistance of the projected image to contrast degradation due to a wide range of ambient light conditions.
