Patent ID: 8564870

Claim:
A method for manufacturing a flexible display arrangement including electrochromic pixel devices arranged in a matrix, said method comprising providing a continuous and flexible insulating layer comprising plastic, the insulating layer forming a carrier for said display arrangement, wherein the thickness of the insulating layer is at least 10 μm and at most 200 μm, and thereafter providing a passage in said insulating layer, wherein the method further comprises in optional order: providing an electrical conductor in said passage; providing a first control layer to a first side of said insulating layer, providing an electrolyte control layer of solidified electrolyte in ionic contact with said first control layer, providing a first pixel layer to a second side of said insulating layer, providing an electrolyte pixel layer of solidified electrolyte in ionic contact with said first pixel layer; arranging a second control layer in ionic contact with said electrolyte control layer, wherein one of said first and second control layers is electronically conducting and electrochemically active and the other is arranged of an electrochemically active organic material, which material has the ability of electrochemically altering its electronic conductivity through change of redox state thereof; arranging a second pixel layer in ionic contact with said electrolyte pixel layer, wherein one of said first and second pixel layers is electronically conducting and electrochemically active and the other pixel layer is arranged of an electrochromic and electrochemically active organic material; and such that said electronic conductor in said passage is in electronic contact with said first control layer and first pixel layer, and said continuous insulating layer forms an insulating layer of each one of said pixel devices.
