Abstract

A method and apparatus for a light emitting device (LED) based modular display have been described.

Claims

1. A method comprising:

receiving a signal representing an image; and

controlling a plurality of light emitting device (LED) based modular displays based on said received signal.

2. The method of claim 1 wherein one or more of said plurality of LED based modular displays further comprises one or more light emitting devices.

3. The method of claim 2 wherein said controlling further comprises controlling the activation of said one or more light emitting devices.

4. The method of claim 3 wherein said activation of said one or more light emitting devices further comprises controlling the intensity of said one or more light emitting devices.

5. The method of claim 4 wherein said controlling the intensity further comprises controlling said intensity based upon a factor determined from a measurement of a test pattern image.

6. The method of claim 4 further comprising mounting one or more of said plurality of LED based modular displays in a pattern capable of displaying said image across one or more of said LED based modular displays.

7. The method of claim 6 further comprising adjusting said mounting such that said image appears seamless to an unaided human eye across said one or more of said plurality of LED based modular displays in said pattern.

8. The method of claim 6 further comprising manipulating said controlling said intensity such that said image appears seamless in display intensity to an unaided human eye across said one or more of said plurality of LED based modular displays in said pattern.

9. The method of claim 2 wherein controlling further comprises moving one or more of said light emitting devices.

10. The method of claim 9 wherein said moving further comprises moving substantially at a resonant frequency said one or more light emitting devices.

11. The method of claim 10 further comprising locating between said one or more of said plurality of LED based modular displays and a surface displaying said image one or more optical elements.

12. The method of claim 10 further comprising coupling one or more optical elements to one or more of said plurality of LED based modular displays.

13. The method of claim 10 wherein said moving further comprises moving one or more of said light emitting devices in opposite directions.

14. The method of claim 2 further comprising optically coupling one or more of said plurality of LED based modular displays to a mirror.

15. The method of claim 14 wherein said mirror has a motion selected from the group consisting of rotating, pivoting, and oscillating.

16. The method of claim 1 wherein each of said LED based modular displays processes less than a full frame of said image.

17. An apparatus comprising:

a plurality of light emitting device (LED) based modular displays mounted in an optical plane and capable of producing an optical output;

one or more optical elements having an input and an output, said one or more optical elements input coupled to receive said LED based modular displays'"'"' optical output; and

a surface coupled to receive the optical output of said one or more optical elements.

18. The apparatus of claim 17 wherein one or more of said light emitting device based modular displays has one or more columns of light emitting diodes.

19. The apparatus of claim 18 wherein one or more of said one or more columns of light emitting diodes are moving at substantially a resonant frequency.

20. The apparatus of claim 19 wherein one or more of said one or more columns of light emitting diodes are moving in opposite directions.

21. An apparatus comprising:

means for receiving a signal representing an image;

means for controlling the movement of one or more light emitting devices in a columnar arrangement;

means for controlling the excitation of one or more of said one or more light emitting devices in said columnar arrangement based on said received signal; and

means for coupling an optical output from said one or more light emitting devices in said columnar arrangement to a viewing surface.

22. A display apparatus comprising:

a plurality of reconfigurable display modules wherein said reconfigurable display modules have a moving mass, and

if said plurality is an even number then half of said reconfigurable display modules'"'"' moving mass is moving in an opposite direction to the other half;

if said plurality is an odd number then one or more of said reconfigurable display modules'"'"' moving mass, or acceleration of said mass, is adjusted to substantially cancel any net force on said display.

23. An apparatus comprising:

a plurality of columns of light emitting devices capable of producing an optical output; and

one or more mirror elements capable of receiving said optical output and reflecting said received optical output onto a viewing surface.

24. The apparatus of claim 23 wherein one or more of said one or more mirror elements has a motion selected from the group consisting of rotating and pivoting.

25. The apparatus of claim 24 wherein more than one of said plurality of columns of light emitting devices is used to produce an image.

26. The apparatus of claim 24 wherein a light emitting device from more than one column of said plurality of columns is used to produce a same pixel of an image.

27. The apparatus of claim 26 wherein said plurality of columns of light emitting devices are not moving.

28. The apparatus of claim 27 wherein each column of said plurality of columns of light emitting devices do not produce light at exactly the same time.
