Abstract

An instrument cluster includes a display using persistence of vision. The display includes a moving portion and light sources carried by the moving portion. The persistence of vision effect gives the display a resolution that is greater than the number of light sources carried by the moving portion. The display may be connected to a vehicle bus such that it can communicate with sensors and other devices connected to the vehicle bus.

Claims

1. A vehicle instrument cluster having a display, the display comprising:

a moving portion; and

light sources carried by the moving portion;

wherein the display generates a resolution that is greater than the number of light sources.

2. The instrument cluster of claim 1, wherein the light sources are arranged in a staggered pattern, the staggered pattern configured to enable the light sources to illuminate the spaces between the light sources when the moving portion is operating.

3. The instrument cluster of claim 2, wherein the light sources are arranged in at least two columns such that the columns of the light sources define spaces there between and wherein the moving portion is configured such that light sources in a first column can illuminate spaces between light sources of a second column.

4. The instrument cluster of claim 1, wherein the moving portion rotates with respect to the display and the light sources are configured to extend from the center of rotation of the moving portion.

5. The instrument cluster of claim 1, further comprising a pointer configured to move with respect to the display.

6. The instrument cluster of claim 1, further comprising a second moving portion with light sources carried therein, wherein the second moving portion is coupled to the first moving portion and the first and second moving portions are configured to move with respect to the display so as to collectively appear as one three-dimensional member.

7. The instrument cluster of claim 1, further comprising:

a power source configured to supply power to the light sources; and

brushings configured to make contact with a conductive portion of the light sources and transfer power thereto while the light sources are moving.

8. The display of claim 1, further comprising:

a power source configured to supply power to the light sources, wherein the power source and light sources are configured to inductively transfer power there between.

9. A display comprising:

light sources configured to move with respect to the display, wherein the display generates a resolution that is greater than the number of light sources; and

a control circuit configured to control operation of the light sources;

wherein the display uses persistence of vision to form an image.

10. The display of claim 9, wherein the control circuit is configured to control the light sources to display tick marks via movement of the light sources.

11. The display of claim 9, wherein the light sources are configured to display a tick mark which varies in size.

12. The display of claim 9, wherein the light sources are configured to be able to form a three-dimensional image via movement thereof

13. The display of claim 9, wherein the control circuit is coupled to a vehicle information bus and wherein the display is reconfigurable in response to a user input.

14. The display of claim 9, wherein the control circuit is coupled to a vehicle information bus and wherein the display is reconfigurable in response to a predetermined event.

15. The display of claim 9, wherein the light sources are configured to collectively appear as one three-dimensional member when in motion.

16. The display of claim 9, further comprising:

a power source configured to supply power to the light sources; and

brushings configured to make contact with a conductive portion of the light sources and transfer power thereto while the light sources are moving.

17. The display of claim 9, further comprising:

a power source configured to supply power to the light sources, wherein the power source and light sources are configured to inductively transfer power there between.

18. A method of increasing the resolution of a display without adding light sources to a plurality of light sources, comprising:

providing a pattern for arranging the plurality of light sources with respect to the display;

illuminating the plurality of light sources; and

moving light sources with respect to the display in a manner to increase the overall resolution of the display.
