Apparatus for displaying an image employing a reflective surface
First Claim
1. Apparatus for displaying an image comprising:
- an image light source that transmits non-polarized image light along a first direction;
a transparent plate having forward facing and rearward facing opposing surfaces with said rearward facing surface having a non-polarizing reflective layer thereon and oriented at an oblique angle relative to said first direction to thereby reflect said image non-polarized light along a second rearward direction toward an operator located rearward of said plate for display thereto; and
light control means interposed between said light source and said plate that restricts viewing of said image at locations forward of said forward surface of said plate.

Abstract
Apparatus for displaying an image wherein the apparatus includes an image light source that transmits light along a first direction. A transparent plate having forward facing and rearward facing opposing surfaces is provided. The rearward facing surface has a reflective layer and is oriented at an oblique angle relative to the first direction so that image light is reflected therefrom along a second rearward direction toward the operator. Light control means is interposed between the light source and the transparent plate in such a manner that it restricts viewing of the image at locations forward of the plate while permitting viewing of the image at locations rearward of the plate.
