摘要:
A process for manufacturing an electrochemically active device comprising the steps of: - providing a substrate (110) comprising an electrode receiving surface portion (111) having substantially constant wetting tension throughout said electrode receiving surface portion, - providing a plurality of first electrodes (120) directly on said electrode receiving surface portion, - leaving intermediate portions (130) of said electrode receiving surface portion (111) free from said electrodes, - providing a layer of electrolyte (140) covering said plurality of first electrodes (120) and said intermediate portions (130), and - wherein wetting tension of the surfaces of the intermediate portions (130) is arranged to act more repelling on the electrolyte compared to the wetting tension of the surfaces of the plurality of first electrodes (120), whereby, the electrolyte is concentrated to the surfaces of the plurality of first electrodes (120), and the surfaces of the intermediate portions (130) are substantially free of electrolyte.

There is disclosed an electrochromic passive -matrix display (100), wherein each passively addressed pixel cell (111, 112, 113) comprises an electrolyte (113) ionically connecting an electrochromic and electrochemically active polymer (121) and a layer of electrically conducting carbon (122). Thus, each pixel has a pronounced threshold voltage sufficient for reducing cross talk in an electrochromic display.

There is disclosed a method for manufacturing a display device arrangement, which comprises a plurality of electrochromic pixel devices (101) arranged in a matrix. First a plastic insulating layer (108) is provided comprising passages (112) for electrical conductors. Thereafter, in optional order, electrical conductors (107) are provided in the passages, pixel layers (102) are printed on one side of the insulating layer, and control layers (103) are printed on the other side of the insulating layer. By this method the manufacturing of a printed electrochromic pixel device is improved.
