Modular video display system
First Claim
1. A visual display system comprising:
- first and second display screens for displaying a predetermined video image on a front surface thereof, wherein each display screen includes a planar display surface, wherein the first and second display screens are mounted in an abutting relationship along respective edges such that the respective display surfaces of said first and second display screens intersect at a predetermined angle, and wherein the front surfaces of said first and second display screens define a concave shape such that a rear surface of each display screen is wider than a corresponding front surface to thereby define a rear edge portion along each respective edge of said first and second display screens which extends outwardly beyond the corresponding front surface;
video projection means for projecting the predetermined video image on said first and second display screens for display thereon;
first and second tabs bonded to the rear edge portion of a respective display screen, wherein each tab extends rearwardly from the rear surface of the respective display screen such that the video image projected by said video projection means on said first and second display screens is not masked by said rearwardly extending tabs, and wherein at least one of said tabs is opaque such that the projected video image will not pass between said display screens to thereby clarify at least the portion of the video image displayed along the edges of said first and second display screens; and
attachment means for attaching said first and second tabs such that said first and second display screens are thereby securely joined.

Abstract
A visual display system, such as a flight simulation system, includes a number of display screens and a number of associated video projectors which project predetermined video images on the display screens in response to control signals provided by an operator. In one embodiment, the display screens are circumscribed by an imaginary sphere having a predetermined radius and centered about the design eye of the visual display system. The design eye is generally positioned in a predetermined fixed relation to the operator such that the distortion of the displayed video image is reduced. In another embodiment, the video projectors are mounted in a linear side-by-side relationship on a rear side of the display screens, thereby reducing the overall size of the visual display system. The visual display system also includes image redirection means, such as fold mirrors, to redirect the video images projected by the aligned video projectors so as to provide the video images to the respective display screens in a direction perpendicular to the planar surface of each display screen. In addition, adjacent display screens can be attached by a pair of rearwardly extending tabs which are positioned so as to not mask the projected video images. At least one of the pair of tabs is opaque such that the projected video images will not pass between the adjacent display screens. Thus, at least the portion of the video image displayed along the edges of the adjacent display screens is clarified.
