ABSTRACT:
A cabinet for use with a visual display for eliminating reflections and glare with respect to an observer having a selected eyepoint is disclosed. The cabinet includes a housing 9 having means mounted to housing 9 for adjustably positioning a visual display having a viewing plane 30. The viewing plane 30 is oriented with respect to a nominal eyepoint 28 of an observer such that the viewing plane 30 is at a selected angle between 65.degree. and 30.degree. with respect to a line of sight extending from the selected nominal eyepoint 28. A support shelf 22 secured to housing 9 supports and locates a keyboard 24 at a viewing position juxtaposed to the visual display CRT 18 such that minimal eye motion is required for an observer to view both visual display 18 and keyboard 24. Also included is an adjustable light obstructing shield 16 having a front edge 26 and a light absorbing inside surface 44. The front edge 26 of light obstructing shield 16, and the display angle of the viewing display 30 are selected such that a light path extending from the eyepoint 28 to any point on the viewing plane 30 is reflected into the light absorbing surface 44 of light obstructing shield 16. This thereby substantially eliminates all glare and reflections originating from an ambient light source.
