Abstract

A display system is provided. An eye-glass is provided. A projector is provided comprising a display device and an optical system for directing an image from the display device to reflect off of the eye-glass and into an eye. The eye-glass and projector may be supported by a frame, which is able to be mounted on a head.

Claims

1. A display system, comprising:

an eye-glass;

a projector, comprising;

a display device; and

an optical system for directing an image from the display device to reflect off of the eye-glass and into an eye.

2. The display system, as recited in claim 1, further comprising a conditioning on the eye-glass that is partially reflective of the image from the display device.

3. The display system, as recited in claim 2, wherein the conditioning is an etching of a surface of the eye-glass.

4. The display system, as recited in claim 2, wherein the conditioning is a beam combiner film on a surface of the eye-glass.

5. The display system, as recited in claim 4, wherein the eye-glass is monocular.

6. The display system, as recited in claim 4, wherein the eye-glass is binocular.

7. The display system, as recited in claim 4, further comprising a communication device electrically connected to the display device.

8. The display system, as recited in claim 4, wherein the beam combiner film is a photo-polymer.

9. The display system, as recited in claim 4, wherein the beam combiner film provides a holographic optical element beam combiner.

10. The display system, as recited in claim 8, wherein the optical system comprises:

a first lens system adjacent to the display device for creating an intermediate image in an intermediate image plane more than 250 mm from a retina of the eye along an optical path; and

a secondary lens system on an opposite side of the intermediate image plane from the display device and first lens system.

11. The display system, as recited in claim 4, further comprising a frame for supporting the display system on a head.

12. The display system, as recited in claim 1, wherein the eye-glass is an auxiliary tilted meniscus and semitransparent minor.

13. The display system, as recited in claim 1, wherein the optical system comprises:

a first lens system adjacent to the display device for creating an intermediate image in an intermediate image plane more than 250 mm from a retina of the eye along an optical path; and

a secondary lens system placed on an opposite side of the intermediate image plane from the display device and first lens system.

14. The display system, as recited in claim 1, further comprising a frame for supporting the display system on a head.

15. The display system, as recited in claim 1, further comprising a communication device electrically connected to the display device.

16. A display system, comprising:

a glasses frame, comprising a mount for supporting the glasses frame on a head;

a first eye-glass supported by the glasses frame;

a second-eye glass supported by the glasses frame;

a projector, supported by the frame, comprising;

a display device; and

an optical system for directing an image from the display device to reflect off of the first eye-glass and into an eye; and

a communication device electrically connected to the projector.

17. The display system, as recited in claim 16, further comprising a conditioning on the first eye-glass that is partially reflective of the image from the display device.

18. The display system, as recited in claim 17, wherein the conditioning is a beam combiner film on a surface of the eye-glass.

19. A method for providing information to a person wearing a head-up display system, comprising:

determining a location of the person;

receiving information related to the location of the person;

projecting the information from a projector, which is part of the head-up display system;

reflecting the information from the projector off of a partially reflecting eye-glass, which is part of the head-up display, into an eye of the person, so that the information from the projector is superimposed over a view passing through the eye-glass.
