4. The array according to claim 1 , wherein edges of the non-transparent portion of the edge seal zone of each package are linearly aligned.
5. The array according to claim 4 , wherein said edges are configured to be disposed along a linear bus bar and connected thereto.
6. The array according to claim 1 , wherein edges of the non-transparent portion of the edge seal zone of each package are aligned in parallel.
7. The array according to claim 1 , wherein
the plurality of packages are arranged in at least two rows; and
the transparent portion of the edge seal zone of each package in a first row overlaps the electroactive area of an adjacent package in the first row and the electroactive area of an adjacent package in a second row.
8. The array according to claim 7 , wherein the electroactive area of each package in the first row overlaps the non-transparent portion of the edge seal zone of an adjacent package in the second row.
9. The array according to claim 1 , wherein the conductive layer is disposed directly on the anode.
10. The array according to claim 1 , additionally comprising an electrically insulating layer disposed between the anode and the conductive layer in the non-transparent portion of the edge seal zone, and configured to electrically isolate the anode from the cathode.
11. The array according to claim 1 , wherein each optoelectronic device is an OLED.
12. An array comprising a plurality of packages positioned in at least one row, each package enclosing an optoelectronic device and overlapping at least one adjacent package;
wherein
each package comprises an edge seal zone defining an electroactive area, and at least a portion of the edge seal zone is transparent;
the electroactive area of a first package in each row is overlapped by the transparent portion of the edge seal zone of an adjacent package;
the transparent portion of the edge seal zone of each package other than the first package in each row overlaps the electroactive area of an adjacent package;
a portion of the edge seal zone of each package is non-transparent,
the electroactive area of each package in the row overlaps the non-transparent portion of the edge seal zone of an adjacent package;
the non-transparent portion of the edge seal zone comprises a conductive layer configured to connect an anode and a cathode of the optoelectronic device to an external power source via a plurality of terminals; and
the conductive layer is disposed directly on the anode.
13. The array according to claim 12 , wherein each of the plurality of packages comprises a single pixel.
14. The array according to claim 13 , wherein the plurality of packages is configured to form a continuous light emitting area.
15. The array according to claim 12 , wherein edges of the non-transparent portion of the edge seal zone of each package are linearly aligned.
16. The array according to claim 12 , wherein said edges are configured to be disposed along a linear bus bar and connected thereto.
17. The array according to claim 12 , wherein edges of the non-transparent portion of the edge seal zone of each package are aligned in parallel.
18. The array according to claim 12 , wherein
the plurality of packages are arranged in at least two rows; and
the transparent portion of the edge seal zone of each package in a first row overlaps the electroactive area of an adjacent package in the first row and the electroactive area of an adjacent package in a second row.
19. The array according to claim 18 , wherein the electroactive area of each package in the first row overlaps the non-transparent portion of the edge seal zone of an adjacent package in the second row.
20. The array according to claim 12 , wherein the cathode and the anode extend through a non-transparent portion of the edge seal zone.
21. The array according to claim 12 , additionally comprising an electrically insulating layer disposed between the anode and the conductive layer in the non-transparent portion of the edge seal zone, and configured to electrically isolate the anode from the cathode.
