Abstract

A composite display is disclosed. In some embodiments, a composite display comprises a set of one or more paddles, a plurality of pixel elements installed on each paddle, and an optic configured to substantially collimate light attached to a surface of each pixel element. In some embodiments, a diffuser film is mounted in front of the set of paddles, wherein the diffuser film diffuses incident collimated light from the pixel elements.

Claims

1. A light source, comprising:

a pixel element configured to emit light; and

a thin film optic configured to substantially collimate light emitted by the pixel element, wherein the thin film optic is attached to a surface of the pixel element.

2. A light source as recited in claim 1, wherein the pixel element comprises a diffused light source.

3. A light source as recited in claim 1, wherein the pixel element comprises a light emitting diode.

4. A light source as recited in claim 1, wherein the thin film optic is associated with Fresnel lens characteristics.

5. A light source as recited in claim 1, wherein the thin film optic comprises a microlens array.

6. A light source as recited in claim 1, further comprising a diffuser film configured to diffuse incident light.

7. A light source as recited in claim 6, wherein the diffuser film is mounted in front of the pixel element.

8. A light source as recited in claim 6, wherein the diffuser film is mounted on a surface of a cover plate positioned in front of the pixel element.

9. A composite display, comprising:

a set of one or more paddles, wherein each paddle is configured to sweep out an area;

a plurality of pixel elements installed on each paddle; and

an optic configured to substantially collimate light attached to a surface of each pixel element.

10. A display as recited in claim 9, wherein the set of paddles is arranged in an out-of-plane paddle configuration.

11. A display as recited in claim 9, wherein a spacing between adjacent temporal pixels associated with the composite display is larger than an out-of-plane spacing between paddles and wherein each temporal pixel of the composite display corresponds to a pixel element at a given sweep location.

12. A display as recited in claim 9, wherein the set of paddles is arranged in an in-plane paddle configuration.

13. A display as recited in claim 9, wherein at least one of the pixel elements comprises a diffused light source.

14. A display as recited in claim 9, wherein at least one of the pixel elements comprises a light emitting diode.

15. A display as recited in claim 9, wherein the optic comprises a lenslet configured to collimate light.

16. A display as recited in claim 9, wherein the optic comprises a thin film optic.

17. A display as recited in claim 9, wherein the optic comprises a microlens array.

18. A display as recited in claim 9, wherein the optic is associated with Fresnel lens characteristics.

19. A display as recited in claim 9, wherein the optic provides local collimation at each pixel element.

20. A display as recited in claim 9, further comprising a diffuser film mounted in front of the set of paddles, wherein the diffuser film diffuses incident collimated light from the pixel elements.

21. A display as recited in claim 9, further comprising a cover plate mounted in front of the set of paddles.

22. A display as recited in claim 9, further comprising a cover plate mounted in front of the set of paddles, wherein a diffuser film is mounted on an inside surface of the cover plate.

23. A display as recited in claim 9, further comprising a cover plate mounted in front of the set of paddles, wherein an anti-reflective coating or film is applied on an outside surface of the cover plate.

24. A display as recited in claim 9, wherein selectively activating one or more of the plurality of pixel elements on each paddle while the paddle sweeps out an area causes at least a portion of an image to be rendered.

25. A method, comprising:

obtaining a set of one or more paddles, wherein each paddle is configured to sweep out an area;

installing a plurality of pixel elements on each paddle; and

attaching an optic configured to substantially collimate light to a surface of each pixel element.
