Abstract

An image display device is disclosed. The image display device includes: an image processing unit; a projecting system; a head-mounted display; and a switch mirror disposed between the projecting system and the head-mounted display for switching lights projected from the image processing unit to the head-mounted display or the projecting system.

Claims

1. An image display device, comprising:

an image processing unit;

a projecting system;

a head-mounted display; and

a switch mirror disposed between the projecting system and the head-mounted display for switching lights projected from the image processing unit to the head-mounted display or the projecting system.

2. The image display device of claim 1, further comprising an attenuator disposed between the switch mirror and the head-mounted display.

3. The image display device of claim 2, wherein the attenuator is a variable attenuator.

4. The image display device of claim 2, wherein the attenuator is an optical film coated on surface of the switch mirror.

5. The image display device of claim 1, wherein the head-mounted display further comprises a polarizer.

6. The image display device of claim 5, further comprising an attenuator coated on the polarizer.

7. The image display device of claim 1, wherein the switch mirror further comprises two different types of reflectivity.

8. The image display device of claim 1, wherein the image process unit comprises a light source, a prism group, and at least one LCoS display panel.

9. The image display device of claim 8, further comprising a light source switching device disposed before the light source for controlling the intensity of light projected from the light source.

10. An image display device, comprising:

an image processing unit;

a projecting system;

a head-mounted display; and

a beam splitter disposed between the projecting system and the head-mounted display for directing lights projected from the image processing unit to the head-mounted display and the projecting system simultaneously.

11. The image display device of claim 10, further comprising an optical fiber for controlling the head-mounted display remotely.

12. The image display device of claim 10, further comprising an optical fiber for controlling the projecting system remotely.

13. The image display device of claim 10, further comprising an optical fiber for controlling the projecting system and the head-mounted display remotely.

14. The image display device of claim 10, further comprising an image enhancer connecting to an optical fiber for enhancing image received by the head-mounted display and the projecting system.

15. The image display device of claim 10, wherein the image processing unit comprises a light source, a prism group, and at least one LCoS display panel.
