Abstract

Rendering an image pixel in a composite display is disclosed. In some embodiments, an image pixel is mapped to a plurality of temporal pixels, and the image pixel is rendered in a composite display using at least a subset of the plurality of temporal pixels to which it is mapped, with the intensity of the image pixel spread across the subset of temporal pixels.

Claims

1. A method for rendering an image pixel in a composite display, comprising:

mapping an image pixel to a plurality of temporal pixels, wherein each temporal pixel corresponds to a pixel element at a given sweep location; and

rendering the image pixel using at least a subset of the plurality of temporal pixels;

wherein an intensity of the image pixel is spread across the subset of temporal pixels.

2. A method as recited in claim 1, wherein the pixel element is installed on a paddle.

3. A method as recited in claim 2, wherein the paddle is configured to sweep out an area.

4. A method as recited in claim 1, wherein the sweep location of the pixel element varies with time.

5. A method as recited in claim 1, wherein the sweep location of the pixel element varies with angle.

6. A method as recited in claim 1, wherein the image pixel is included in an image being rendered by temporal pixels including the subset of temporal pixels in the composite display.

7. A method as recited in claim 1, wherein the plurality of temporal pixels includes one or more redundant temporal pixels.

8. A method as recited in claim 1, wherein the intensity is divided equally across the subset of temporal pixels.

9. A method as recited in claim 1, wherein the intensity is not divided equally across the subset of temporal pixels.

10. A method as recited in claim 1, wherein the intensity includes an amplitude.

11. A method as recited in claim 1, wherein the intensity includes a duty cycle.

12. A method as recited in claim 1, wherein the intensity comprises a grayscale value.

13. A method as recited in claim 1, further comprising using a driver chip for pixel elements including the pixel element that has sufficient bit depth to spread the intensity across the subset of temporal pixels.

14. A method as recited in claim 1, further comprising creating a pixel map.

15. A method as recited in claim 1, wherein mapping comprises overlaying an image over a display area of the composite display.

16. A system for rendering an image pixel in a composite display, comprising:

a processor configured to;

map an image pixel to a plurality of temporal pixels, wherein each temporal pixel corresponds to a pixel element at a given sweep location; and

render the image pixel using at least a subset of the plurality of temporal pixels, wherein an intensity of the image pixel is spread across the subset of temporal pixels; and

a memory coupled to the processor and configured to provide instructions to the processor.

17. A system as recited in claim 16, wherein the intensity includes one or more of an amplitude and a duty cycle.

18. A computer program product for rendering an image pixel in a composite display, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

mapping an image pixel to a plurality of temporal pixels, wherein each temporal pixel corresponds to a pixel element at a given sweep location; and

rendering the image pixel using at least a subset of the plurality of temporal pixels;

wherein an intensity of the image pixel is spread across the subset of temporal pixels.

19. A computer program product as recited in claim 18, wherein the intensity includes one or more of an amplitude and a duty cycle.

20. A computer program product as recited in claim 18, wherein the intensity is divided equally across the subset of temporal pixels.
