Abstract

A novel display system for observing virtual and real images. The display system includes a light redirection surface or reflective surface (e.g, mirrored surface) to display, for example, a virtual image. The system also has a light emitting surface, or LES, which includes first and second sides directly opposite from each other. The LES emits light to form the virtual image at an apparent distance behind the reflective surface. An observing region is also included on the second side of the LES for observing the image through the LES. The LES is static.

Claims

1. A method for observing an image, said method comprising:

emitting light from a first side of a light emitting surface (“

LES”

) to a reflective magnifying optical system (“

RMOS”

) within a field of view of an observer, whereupon said LES providing said light to form a virtual image behind said RMOS, said image being of a sufficient size for a person of ordinary vision to view comfortably without further magnification; and

observing said image through said LES on a second side, said second side being substantially opposite of said first side, said LES being constructed to permit a portion of said light from said RMOS be observed by said observer without substantial optical distortion or attenuation, wherein said LES comprising a static light emitting structure.

2. The method of claim 1 wherein said static light emitting structure selectively emits light from light emitting materials to provide said image from said RMOS.

3. The method of claim 1 wherein said static light emitting structure selectively blocks light from said light emitting materials.

4. The method of claim 1 wherein said static light emitting structure is substantially stationary.

5. The method of claim 1 wherein said LES comprises a source selected from a plurality of electrical potential activated materials, a plurality of UV activated materials, and a plurality of infrared activated materials.

6. The method of claim 5 wherein said electrical potential activated materials comprise organic light emitting diodes, light emitting diodes (LED), electroluminescent materials, porous silicon, electrically addressed phospors, or illuminated light valves.

7. The method of claim 5 wherein said UV activated materials is selected from a UV absorbing dye and visible emitting dye material, a UV absorbing and visible emitting phosphor-type material, or UV absorbing and visible emitting semiconductor-type material.

8. The method of claim 5 wherein said infrared activated materials is selected from an infrared absorbing dye and visible emitting dye-type material, a infrared absorbing and visible emitting phosphor-type material, or infrared absorbing and visible emitting semiconductor-type material.

9. The method of claim 1 wherein said RMOS comprises a substantially spherical concave mirror.

10. The method of claim 9 wherein said LES comprises a substantially spherical surface, said first side corresponds to an outside of said substantially spherical surface, said second side corresponds to an interior of said spherical surface, and said LES comprising an LES radius that is greater than about half of a radius of said RMOS.

11. The method of claim 9 wherein said first side of said LES corresponds to an outside surface, said second side of said LES corresponding to an interior surface, said LES being within a volume defined by the RMOS and within a radius that is greater than about half of a radius of said RMOS.

12. The method of claim 1 wherein said RMOS includes a horizontal viewing angle of greater than about 180 degrees.

13. The method of claim 1 wherein said RMOS includes a horizontal viewing angle of about 360 degrees.

14. The method of claim 1 wherein said RMOS includes a vertical viewing angle of greater than about 90 degrees.

15. The method of claim 1 wherein said RMOS includes a vertical viewing angle of about 180 degrees.

16. A light emitting surface, said light emitting surface comprising:

a first side coupled oppositely to a second side, said first side comprising a plurality of static sources for emitting electromagnetic energy to project as an image onto a RMOS, said image projecting off of said RMOS and passing through said first side to be substantially visible by an observer facing at said second side without further magnification;

wherein said image being substantially visible to said observer having a horizontal viewing angle greater than about 180 degrees and a vertical viewing angle greater than about 90 degrees.

17. A virtual reality system, including a computer having a memory, said memory comprising:

a code directed to selectively emit light from a first side of a light emitting surface (“

LES”

) to a RMOS within a field of view of an observer, whereupon said LES providing said light to form an image behind said surface and allowing a user to observe said image through said LES on a second side, said image being of a sufficient size for a person of ordinary vision to comfortably view without further magnification, said second side being substantially opposite of said first side, said LES being constructed to permit a portion of said light from said RMOS to be observed by said observer without substantial optical distortion or attenuation;

wherein said LES comprising a static light emitting structure.
