Abstract

A tiled electro-optic imaging device includes two or more tiles each tile having a two dimensional array of pixels and at least one non-linear edge, the tiles being aligned edge to edge such that pixels from the tiles are inter-digitated along the non-linear edge, whereby the visibility of the non-linear edge is reduced and the visual uniformity of the device is enhanced.

Claims (30)

1. A tiled electro-optic imaging device, comprising: two or more tiles, each tile having a two dimensional array of pixels and at least one non-linear edge, the non-linear edges of the tiles being aligned edge to edge such that pixels along the non-linear edge of one tile are inter-digitated with pixels along a complementary non-linear edge of an adjacent tile, whereby the visibility of the non-linear edge is reduced and the visual uniformity of the device is enhanced.

2. The device claimed in claim 1 , wherein the pixels are light sensing elements and the device is an image sensor.

3. The device claimed in claim 1 , wherein the pixels are light emitting elements and the device is an image display device.

4. The device claimed in claim 3 , wherein the display device is a digital emissive flat-panel display.

5. The device claimed in claim 4 , wherein the display device is an OLED display device.

6. The device claimed in claim 1 , wherein the pixels are inter-digitated by more than one pixel.

7. The device claimed in claim 1 , wherein the non-linear edges are sinusoidal.

8. The device claimed in claim 1 , wherein the edges are saw-tooth shaped.

9. The device claimed in claim 1 , wherein the edges are step-shaped.

10. The device claimed in claim 9 , wherein the steps are inter-digitated periodically by more than one step.

11. The device claimed in claim 1 , wherein each tile comprises a substrate, the array of pixels being formed on the substrate, and one or more edges of the substrate define the non-linear edge.

12. The device claimed in claim 1 , wherein each tile comprises a substrate, the array of pixels being formed on the substrate, and an image expanding fiber optic face plate having at least one fiber per pixel; and one or more edges of the fiber optic face plate define the non-linear edge.

13. The device claimed in claim 1 , wherein the tiles are rectangular and arranged in aligned rows and columns.

14. The device claimed in claim 1 , wherein the tiles are rectangular and are arranged in slanted rows and columns.

15. The device claimed in claim 1 , wherein the tiles are rectangular and are arranged in rows and columns slanted at 45 degrees.

16. A method of making a tiled electro-optic imaging device, comprising the steps of: providing a plurality of tiles, each tile having a two dimensional array of pixels and at least one non-linear edge, and arranging the non-linear edges of the tiles edge to edge such that pixels along the non-linear edge of one tile are inter-digitated with pixels along a complementary non-linear edge of an adjacent tile, whereby the visibility of the non-linear edge is reduced and the visual uniformity of the device is enhanced.

17. The method claimed in claim 16 , wherein the pixels are light sensing elements and the device is an image sensor.

18. The method claimed in claim 16 , wherein the pixels are light emitting elements and the device is an image display device.

19. The method claimed in claim 18 , wherein the display device is a digital emissive flat-panel display.

20. The method claimed in claim 19 , wherein the display device is an OLED display device.

21. The method claimed in claim 16 , wherein the pixels are inter-digitated by more than one pixel.

22. The method claimed in claim 16 , wherein the non-linear edges are sinusoidal.

23. The method claimed in claim 16 , wherein the edges are saw-tooth shaped.

24. The method claimed in claim 16 , wherein the edges are step-shaped.

25. The method claimed in claim 24 , wherein the steps are inter-digitated periodically by more than one step.

26. The method claimed in claim 16 , wherein each tile comprises a substrate, the array of pixels being formed on the substrate, and one or more edges of the substrate define the non-linear edge.

27. The method claimed in claim 16 , wherein each tile comprises a substrate, the array of pixels being formed on the substrate, and an image expanding fiber optic face plate having at least one fiber per pixel; and one or more edges of the fiber optic face plate define the non-linear edge.

28. The method claimed in claim 16 , wherein the tiles are rectangular and arranged in aligned rows and columns.

29. The method claimed in claim 16 , wherein the tiles are rectangular and are arranged in an offset rows and columns.

30. The method claimed in claim 16 , wherein the tiles are rectangular and are arranged in slanted rows and columns.
