<p>A video wall (10) has a plurality of spatial object image display devices (20), each spatial object image display device (20) including a luminous display screen (22) for providing a first image (24). Each spatial object image display device (20) also includes a lens (26) operatively spaced apart from the luminous display screen (22) for projecting the first image (24) to appear as a first spatial object (28). The luminous display screen (22) and the lens (26) of each spatial object display device (20) are mounted within a surrounding housing, excluding substantially all light from within the housing, except through an aperture (32) in the housing. The lens (26) is mounted in proximity to and substantially covering the aperture (32). The housing further includes a shroud (34) extending from the perimeter of the aperture (32) far enough to shield the lens (26), but not far enough to surround the first spatial object (28).</p> |
