Abstract

A display device for creating the illusion of a three dimensional image is disclosed. The device includes a generally planar light transmitting surface having both a background image and an intermediate image formed thereon, the foreground image being in focus, the background scene or image being out of focus. A generally planar mirror has a foreground image located thereon and is maintained at an acute angle with respect to the light transmitting surface such that the light transmitting surface may be viewed by looking at the mirror along an axis which is within the acute angle. A light source is provided for projecting light through the light transmitting surface onto the mirror for reflection thereby.

Claims

1. A display device, comprising:

a generally planar light transmitting surface having both a background and an intermediate image located thereat, said intermediate image being in focus, said background image being out of focus;

a generally planar mirror having a foreground image located thereat;

first means for projecting light through said background and intermediate images onto said mirror for reflection thereby; and

second means for maintaining said light transmitting surface at an acute angle with respect to said mirror such that said light transmitting surface may be viewed by looking at said mirror along an axis which is within said acute angle whereby said background, said foreground and said intermediate images are superimposed on each when viewed along said axis to create the illusion that said intermediate image is located behind said foreground image and said background image is located behind both said foreground image and said intermediate image, thereby creating a three dimensional scene.

2. The display device of claim 1, further including a light box, said light transmitting surface constituting one surface of said light box, said first means including a light source located in said light box.

3. The display device of claim 2, wherein said second means includes a support for said mirror which is integral with said light box.

4. The display device of claim 2, wherein said background and intermediate images are formed on a light transmitting image carrier positioned at said light transmitting surface.

5. The display device of claim 2, wherein said foreground image is formed on a sheet which is adhered to a front surface of said mirror.

6. The display device of claim 1, wherein said background and intermediate images are formed on a light transmitting substrate which is located on said light transmitting surface.

7. The display device of claim 1, wherein said mirror is a full reflecting mirror.

8. The display device of claim 1, wherein said foreground image is in focus.
