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.
