Abstract

A system for generating a display is disclosed. The system includes a base on which one or more paddles are mounted, wherein each paddle includes a plurality of pixel elements and is configured to sweep out an area during a paddle cycle, a processor configured to generate a script based at least in part on a pixel map and an image, and a pixel element driver configured to receive at least a portion of the script and activate a pixel element on a paddle when the pixel element coincides with an image pixel of the image. At least a portion of the image is represented on the display by activating the pixel element.

Claims

1. A system for generating a display including:

a base on which one or more paddles are mounted, wherein each paddle includes a plurality of pixel elements and is configured to sweep out an area during a paddle cycle;

a processor configured to generate a script based at least in part on a pixel map and an image; and

a pixel element driver configured to receive at least a portion of the script and activate a pixel element on a paddle when the pixel element coincides with an image pixel of the image;

wherein at least a portion of the image is represented on the display by activating the pixel element.

2. A system as recited in claim 1, wherein the pixel element is a light emitting diode (LED).

3. A system as recited in claim 1, wherein the processor is a master processor configured to generate a master script for two or more paddles.

4. A system as recited in claim 1, wherein the processor is a local processor configured to generate a local script for the paddle.

5. A system as recited in claim 1, wherein the script is stored in SDRAM.

6. A system as recited in claim 1, further including a serializer configured to serialize at least a portion of the script.

7. A system as recited in claim 1, further including a paddle base comprising a portion of the base on which the paddle is mounted, wherein the portion includes one or more devices associated with the paddle.

10. A system as recited in claim 1, wherein the script comprises a sequence of data indicating which pixel elements on the paddle to activate, intensities associated with the pixel elements, and when to activate the pixel elements.

11. A system as recited in claim 1, wherein the script includes one or more of:

LED driver chip control commands, timing information, LED current settings, and LED grayscale information.

12. A system as recited in claim 1, wherein the script is pre-generated or generated in real time.

13. A system as recited in claim 1, wherein the script comprises a master script and further comprising an FPGA configured to parse the master script into local script data for each paddle.

8. A system as recited in claim 8, further including an optical link between the paddle base and the paddle.

9. A system as recited in claim 8, further including an optical link between the base and the paddle base.

14. A method for providing a display including:

sweeping out an area during a paddle cycle, wherein sweeping is performed by one or more paddles mounted on a base, wherein each paddle includes a plurality of pixel elements;

generating a script based at least in part on a pixel map and an image; and

receiving at least a portion of the script and activating a pixel element on a paddle when the pixel element coincides with an image pixel of the image;

wherein at least a portion of the image is represented on the display by activating the pixel element.

15. A method as recited in claim 14, wherein the pixel element is a light emitting diode (LED).

16. A method as recited in claim 14, wherein a master processor is configured to generate a master script for two or more paddles.

17. A method as recited in claim 14, wherein a local processor is configured to generate a local script for the paddle.

18. A method as recited in claim 14, wherein the script comprises a sequence of data indicating which pixel elements on the paddle to activate, intensities associated with the pixel elements, and when to activate the pixel elements.

19. A method as recited in claim 14, wherein the script is pre-generated or generated in real time.

20. A method as recited in claim 14, wherein the script comprises a master script and wherein an FPGA is configured to parse the master script into local script data for each paddle.
