Abstract

A composite display is disclosed. In some embodiments, a composite display comprises a paddle configured to sweep out an area and a plurality of pixel elements mounted on the paddle. Selectively activating one or more of the plurality of pixel elements during a fractional rotation of the paddle within its sweep area causes an image to be rendered.

Claims

1. A composite display, comprising:

a paddle configured to sweep out an area; and

a plurality of pixel elements mounted on the paddle;

wherein selectively activating one or more of the plurality of pixel elements during a fractional rotation of the paddle within its sweep area causes an image to be rendered.

2. A composite display as recited in claim 1, wherein the fractional rotation comprises a first fractional rotation and the image comprises a first image and wherein selectively activating one or more of the plurality of pixel elements during a second fractional rotation of the paddle within its sweep area causes a second image to be rendered.

3. A composite display as recited in claim 1, wherein the image comprises a frame of video data.

4. A composite display as recited in claim 1, wherein a plurality of consecutive frames of video data are rendered during a full rotation of the paddle through its sweep area.

5. A composite display as recited in claim 1, wherein the paddle comprises a disc.

6. A composite display as recited in claim 5, wherein the plurality of pixel elements are mounted along one or more radii of the disc.

7. A composite display as recited in claim 5, wherein no pixel elements are mounted in a center portion of the disc.

8. A composite display as recited in claim 5, wherein pixel elements are mounted in a center portion of the disc.

9. A composite display as recited in claim 1, wherein a rotational rate of the paddle is less than or equal to 2 Hz.

10. A composite display as recited in claim 1, wherein a different image is rendered each fractional rotation of the paddle within its sweep area.

11. A composite display as recited in claim 1, wherein the pixel elements are mounted in arrays on the paddle.

12. A composite display as recited in claim 11, wherein a rotational rate of the paddle is inversely proportional to the number of arrays of pixel elements mounted on the paddle for a given resolution.

13. A composite display as recited in claim 1, wherein the paddle is in the shape of a belt configured to rotate around one or more rollers.

14. A composite display as recited in claim 1, wherein a maximum display area of the composite display corresponds to the sweep area.

15. A composite display as recited in claim 1, wherein a maximum display area of the composite display is divided into one or more smaller display areas.

16. A composite display as recited in claim 15, wherein the one or more smaller display areas are reconfigurable.

17. A composite display as recited in claim 1, wherein at least one pixel element comprises a light emitting diode (LED).

18. A method comprising,

obtaining a paddle configured to sweep out an area;

and

mounting a plurality of pixel elements on the paddle;

wherein selectively activating one or more of the plurality of pixel elements during a fractional rotation of the paddle within its sweep area causes an image to be rendered.

19. A method as recited in claim 18, wherein a different image is rendered each fractional rotation of the paddle within its sweep area.

20. A method as recited in claim 18, wherein a plurality of consecutive frames of video data are rendered during a full rotation of the paddle through its sweep area.
