Abstract

A system and method for manufacturing a display device having an electrically connected front plate and back plate are disclosed. In one embodiment, the method comprises printing conductive raised contours onto a non-conductive back plate, aligning the back plate with a non-conductive front plate such that the raised contours align with conductive routings on the front plate to electrically connect the raised contours and the routings, and sealing the back plate and the front plate.

Claims

1. A method of manufacturing an electromechanical device, the method comprising:

printing conductive raised contours onto a non-conductive back plate;

aligning the back plate with a non-conductive front plate such that the raised contours align with conductive routings on the front plate to electrically connect the raised contours and the routings; and

sealing the back plate and the front plate.

2. The method of claim 1, further comprising printing conductive traces on the back plate.

3. The method of claim 2, wherein the conductive traces electrically connect the conductive routings to driver circuitry.

4. The method of claim 2, wherein the conductive traces electrically connect the conducting routings to one or more conductive vias extending through the back plate.

5. The method of claim 1, further comprising printing a desiccation pattern on the back plate.

6. The method of claim 3, further comprising depositing a desiccant upon the desiccation pattern.

7. The method of claim 1, further comprising providing the front plate.

8. The method of claim 7, further comprising plating the conductive routings on the front plate.

9. The method of claim 7, further comprising generating a plurality of display elements on the front plate.

10. The method of claim 9, wherein the display elements are interferometric modulators.

11. The method of claim 1, wherein printing conductive raised contours comprises inkjet printing.

12. The electromechanical device produced by claim 1.

13. A system for manufacturing an electromechanical device, the system comprising:

a printer configured to print conductive raised contours onto a non-conductive back plate;

a coordinator configured to align the back plate with a non-conductive front plate such that the raised contours align with conductive routings on the front plate to electrically connect the raised contours and the routings; and

a sealer configured to seal the back plate and the front plate.

14. The system of claim 13, wherein the printer comprises an inkjet printer.

15. The system of claim 13, wherein the coordinator comprises at least one of a motor, a processor, or a position sensor.

16. The system of claim 13, wherein the sealer comprises a sealant injector.

17. A system for manufacturing an electromechanical device, the system comprising:

means for printing conductive raised contours onto a non-conductive back plate;

means for aligning the back plate with a non-conductive front plate such that the raised contours align with conductive routings on the front plate to electrically connect the raised contours and the routings; and

means for sealing the back plate and the front plate.

18. The system of claim 17, wherein the means for printing comprises an inkjet printer, wherein the means for aligning comprises a support or motor, or wherein the means for sealing comprises a press.
