Abstract

A display device and method of fabricating the same. The display device comprises a first array of transparent conductors. The first array of transparent conductors has a first pitch defined by a first distance between adjacent transparent conductors of the first array of transparent conductors. The display device further comprises a second array of conductors disposed on a plurality of integrated circuit (IC) devices coupled to a carrier, which couples to the display device. The second array of conductors has a second pitch defined by a second distance between adjacent conductors of the second array of conductors. The first pitch and the second pitch are substantially similar. The first array of transparent conductors interconnects the second array of conductors.

Claims

1. A display device comprising:

a first array of transparent conductors deposited on a display panel, the first array of transparent conductors having a first pitch defined by a first distance between first adjacent transparent conductors;

a carrier having a plurality of blocks each having an integrated circuit (IC) device disposed therein is coupled to the display panel, the carrier having a plurality of receptor sites configured to receive the plurality of functional blocks; and

a second array of conductors disposed on the plurality of IC devices, the second array of conductors having a second pitch defined by a second distance between second adjacent conductors wherein the first pitch and the second pitch are substantially similar and wherein the first array of transparent conductors interconnect the second array of conductors.

2. The display device as in claim 1 wherein the second array of conductors substantially surrounds a perimeter of each of the plurality of the blocks.

3. The display device as in claim 1 wherein the second array of conductors interconnects the first array of transparent conductors along at least one edge of the carrier.

4. The display device as in claim 1 wherein the display device has a first length, the carrier has a second length wherein the second length is substantially similar to the first length.

5. The display device as in claim 1 wherein the display is flexible.

6. The display device as in claim 1 wherein the plurality of blocks are NanoBlocks.

7. The A display device as in claim 1 wherein the carrier is flexible.

8. A method of making a display device comprising:

coupling a carrier having a plurality of blocks each having an integrated circuit (IC) device disposed therein to a display panel, the display panel comprising a first array of transparent conductors having a first pitch defined by a first distance between first adjacent transparent conductors, the plurality of IC devices comprising a second array of conductors disposed thereon, the second array of conductors having a second pitch defined by a second distance between second adjacent conductors, wherein the first pitch and the second pitch are substantially similar; and

interconnecting the first array of transparent conductors to the second array of conductors.

9. The method of making a display device as in claim 8 wherein the second array of conductors substantially surrounds a perimeter of each of the plurality of the blocks.

10. The method of making a display device as in claim 8 wherein the second array of conductors interconnect the first array of transparent conductors along at least one edge of the carrier.
