Claims
- 1. A rear electrode structure for electrically addressable displays, the structure comprising:
a substrate; a first electrode disposed on a first side of said substrate; and a conductor disposed on a second side of said substrate, said substrate defining at least one conductive via in electrical communication with said first electrode and said conductor.
- 2. The rear electrode structure of claim 1, wherein said conductor is completely covered in an electrically conducting material.
- 3. The rear electrode structure of claim 1, further comprising at least one electrophoretic display element disposed on said substrate adjacent said electrode.
- 4. The rear electrode structure of claim 1, wherein said at least one conductive via is in electrical communication with a network of conductors.
- 5. The rear electrode structure of claim 4, wherein said network of conductors is in electrical communication with an edge conductor.
- 6. The rear electrode structure of claim 1, wherein said substrate comprises a flex circuit coated with conductive material, and wherein said first electrodes and said conductor are etched into said conductive material.
- 7. The rear electrode structure of claim 1, wherein said substrate comprises a printed circuit board, said printed circuit board having one or more copper pads etched in an arbitrary shape.
- 8. The rear electrode structure of claim 1, wherein said substrate consists of a thin sheet made of a dielectric material selected from the group of materials consisting of polyester, polyimide, and glass and wherein said first electrode comprises conductive ink capable of filling said at least one conductive via.
- 9. The rear electrode structure of claim 1, wherein said conductor comprises of a printable display material and wherein a dielectric coating and a layer of conductive ink is printed on said printable display material.
