Abstract
A desk top CRT visual display system for eliminating reflections and glare with respect to an observer having a selected eyepoint is disclosed. The system includes a CRT 18 having a viewing plane 30. The CRT 18 is oriented with respect to a nomimal eyepoint 22 of an observer such that the viewing plane 30 is at a selected angle of between 70.degree. and 30.degree. with respect to a line of sight extending from the selected nominal eyepoint 22. The system is supported by a desk top 26 which also typically supports keyboard 28 at a viewing position juxtaposed to the visual display CRT 18. The system also includes a light obstructing top shield 16 having a front edge 44 and a light absorbing under surface 46. The front edge 44 of light obstructing shield 16, and the display angle of the viewing plane 30 of CRT 18 are selected such that a light path extending from the eyepoint 22 to any point on the viewing plane 30 is reflected into the light absorbing surface 46 of light obstructing top shield 16. This thereby substantially eliminates all glare and reflections originating from an ambient light source when the screen is viewed from the nominal eyepoint 22.
