Abstract

A compact mirror-based three-dimensional (3D) display system with a polarizer between the viewer in a viewing space and a beam splitter. The beam splitter may be a half-silvered mirror, and the polarizer may be a circular polarizer that acts to cancel the undesired reflections including that of a viewer. A half prop often will be positioned between the beam splitter and the polarizer. The mirror-based 3D display system may also utilize additional components for creating effects that move in depth and that are in 3D. This may include rotation of the display (or its monitor or display screen) from parallel to an offset angle to allow displayed images to move toward and away from the mirror and not be locked into a plane parallel to and often abutting the mirror. The display system may further include configurations that provide a backdrop image behind the displayed image.

First claim

We claim:

1 . A display system for providing a three-dimensional (3D) effect with controlled reflections, comprising:
a viewing space; a planar beam splitter with a first surface facing the viewing space and a second surface facing away from the viewing space; a polarizer disposed between the first surface of the beam splitter and the viewing space blocking light originating in the viewing space and reflected by the beam splitter; a physical prop positioned between the beam splitter and the polarizer; and a display with a display screen facing the second surface of the beam splitter, wherein the display is operated to provide a displayed image on the display screen viewable in the viewing space concurrently with light from the physical prop reflected by the beam splitter through the polarizer.

2 . The display system of claim 1 , wherein the polarizer is a circular polarizer with a planar or curved body.

3 . The display system of claim 2 , wherein the polarizer further comprises an anti-reflection coating on a surface of the body facing the viewing space.

4 . The display system of claim 1 , further comprising a framing panel disposed between the polarizer and the physical prop, wherein the framing panel includes an aperture passing light to and from the viewing space and wherein the framing panel further includes a back surface facing the first surface of the beam splitter and including backdrop imagery or objects.

5 . The display system of claim 1 , wherein the display comprises a 3D display.

6 . The display system of claim 1 , further comprising a lens disposed between the display screen and the beam splitter focusing the displayed image to a location between the beam splitter and the polarizer.

7 . The display system of claim 1 , wherein the polarizer comprises a ¼ wave film proximate to the physical prop and a horizontal polarizer proximate to the viewing space and wherein the display system further comprises a transparent polarization preserving screen disposed between the ¼ wave film and the horizontal polarizer, a projector projecting a backdrop image onto a surface of the transparent polarization preserving screen facing the viewing space, and a circular polarizer disposed between the display and the beam splitter.

8 . The display system of claim 7 , wherein the ¼ wave film and the horizontal polarizer are both planar, are spaced apart, and are arranged to be parallel.

9 . The display system of claim 7 , wherein the projector is a short throw video projector and wherein the projector and display are concurrently operated to provide the displayed image and to project the backdrop image.

10 . The display system of claim 1 , wherein the physical prop is a half prop positioned to abut the first surface of the beam splitter.

11 . The display system of claim 1 , wherein the display is rotated at an offset angle in the range of 15 to 60 degrees to the second surface of the beam splitter.

12 . A display system for providing a three-dimensional (3D) effect with controlled reflections to a viewer in a viewing space, comprising:
a beam splitter with a first surface facing the viewing space and a second surface facing away from the viewing space; a polarizer disposed between the first surface of the beam splitter and the viewing space blocking light originating in the viewing space and reflected by the beam splitter; a physical prop positioned between the beam splitter and the polarizer; and a display providing an image to the second surface of the beam splitter, wherein the display is rotated from the second surface of the beam splitter by an offset angle in the range of 15 to 60 degrees.

13 . The display system of claim 12 , wherein the polarizer is a circular polarizer with a planar or curved body.

14 . The display system of claim 12 , further comprising an opaque framing panel disposed between the polarizer and the physical prop, wherein the framing panel includes an aperture passing light to and from the viewing space, and wherein the framing panel further includes a back surface facing the first surface of the beam splitter and including backdrop imagery or objects.

15 . The display system of claim 12 , wherein the display comprises a 3D display.

16 . The display system of claim 12 , further comprising a lens disposed between the display screen and the beam splitter focusing the image to a location between the beam splitter and the polarizer.

17 . The display system of claim 12 , wherein the polarizer comprises a ¼ wave film proximate to the physical prop and a horizontal polarizer proximate to the viewing space and wherein the display system further comprises a transparent polarization preserving screen disposed between the ¼ wave film and the horizontal polarizer, a projector projecting a backdrop image onto a surface of the transparent polarization preserving screen facing the viewing space, and a circular polarizer disposed between the display and the beam splitter.

18 . The display system of claim 12 , wherein the physical prop is a half prop positioned to abut the first surface of the beam splitter.

19 . A display system for providing a three-dimensional (3D) effect with controlled reflections to viewers in a viewing space, comprising:
a half-silvered mirror with a first surface facing the viewing space and a second surface facing away from the viewing space; a circular polarizer disposed between the first surface of the beam splitter and the viewing space blocking light originating in the viewing space and reflected by the beam splitter; a half prop positioned between the half-silvered mirror and the circular polarizer with a planar back wall facing and substantially co-planar with the first surface of the half-silvered mirror; and a display with a display screen facing the second surface of the half-silver mirror, wherein the display is operated to provide a displayed image on the display screen viewable in the viewing space concurrently with light from the half prop reflected by the beam splitter through the circular polarizer.

20 . The display system of claim 19 , wherein the display screen is rotated about a longitudinal axis parallel to a longitudinal axis of the half-silvered mirror to offset angle in the range of 15 to 60 degrees measured between the second surface of the half-silvered mirror and the display screen.

21 . The display system of claim 19 , further comprising a framing panel disposed between the circular polarizer and the half prop, wherein the framing panel includes an aperture passing light to and from the viewing space and wherein the framing panel further includes a back surface facing the first surface of the half-silvered mirror and including backdrop imagery or objects.

22 . The display system of claim 19 , wherein the display comprises a 3D display.

23 . The display system of claim 19 , further comprising a lens disposed between the display screen and the half-silvered mirror focusing the displayed image to a location between the half-silvered mirror and the circular polarizer.
