Abstract

A visual display unit creating a three-dimensional volumetric space. The display includes a first screen in a first focal plane, wherein the first screen displays a first image. The display includes a second screen in a second focal plane distinct from the first focal plane, wherein the second screen displays a second image, and wherein the second screen at least partially overlaps the first screen. The display includes a physical object located between the first screen and said second screen, wherein at least one of the first and second images is displayed in response to a placement of the physical object.

Claims

1. A display system for a vehicle comprising:

a first display screen, of the display system for the vehicle, in a first plane, wherein said first display screen is for displaying a first image;

a second display screen in a second plane, wherein said second display screen is for displaying a second image, and wherein said display system is configured so that the first and second images, from the first and second display screens respectively, are to at least partially overlap;

a physical object located between said first display screen and said second display screen, wherein the display system is configured so that at least one of said first and second images is displayed in response to a placement of said physical object; and

an emissive layer comprising a sheet provided between said first display screen and said second display screen and configured to provide light to said first display screen and the physical object.

2. The display system of claim 1, wherein said first screen is configured to display the first image in response to movement of the physical object.

3. The display system of claim 2, wherein said second display screen is configured to display the second image in response to display of the first image.

4. The display system of claim 1, wherein the second display screen is configured to display the second image in response to movement of the physical object.

5. The display system of claim 1, wherein the physical object is configured to move in response to at least one of said first image and second image.

6. The display system of claim 1, wherein said physical object is opaque.

7. The display system of claim 1, wherein said physical object is transparent.

8. The display system of claim 1, wherein said physical object comprises a vehicle dash gauge needle.

9. The system of claim 1, wherein said emissive layer comprises a TOLED.

10. A method for operating a visual display system for a vehicle, the method comprising:

providing a first display screen in a first plane, wherein said first display screen displays a first image;

providing a second display screen in a second plane different from the first plane, wherein said second display screen displays a second image, and wherein said second display screen at least partially overlaps said first display screen;

providing a physical object between at least said first display screen and said second display screen, wherein at least one of said first and second images is displayed in relation to said physical object; and

providing an emissive layer comprising a sheet between said first display screen and said second display screen, said emissive layer providing light to said first display screen and said physical object.

11. The method of claim 10, further comprising displaying said first image on said first screen in response to movement of said physical object.

12. The method of claim 11, further comprising displaying said second image on said second screen in response to display of said first image.

13. The method of claim 10, further comprising displaying said second image on said second screen in response to movement of said physical object.

14. The method of claim 10, further comprising moving said physical object in response to at least one of said first image and second image.

15. The method of claim 10, wherein said emissive layer comprises a TOLED.

16. The method of claim 10, wherein said first and second display screens comprise first and second LCD screens, respectively.

17. The method of claim 10, wherein said wherein said physical object is opaque.

18. The method of claim 10, wherein said wherein said physical object is at least partially transparent.

19. The method of claim 10, wherein said wherein said physical object comprises a vehicle gauge needle.
