    摘要： 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.

    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.

    摘要： A directly addressable display device comprising at least one pixel cell (1-9), each pixel cell (1-9) being arranged for displaying a symbol, which symbol is repeatedly switchable between an on-state and an off-state, wherein each pixel cell (1-9) comprises an electrochromic layer (110) comprising an electrochromic and electrochemically active organic polymer material being electrochemically switchable between two different visually detectable coloring states; a counter electrode layer (140) comprising an electronically conductive material, wherein said counter electrode layer (140) in the viewing direction of the display device is arranged behind said electrochromic layer (110); an electrolyte layer (130), which electrolyte layer (130) is solid and arranged spatially between, and in ionic contact with, said electrochromic layer (110) and said counter electrode layer (140); a symbol defining layer (120) which is electronically and ionically insulating, arranged in direct ionic contact with said electrochromic layer (110), and which comprises one or more openings (121-129) which encloses said electrolyte layer (130) and defines the shape of said symbols; wherein said electrolyte layer (130) comprises a composition comprising a polyelectrolyte selected from one or more cationic polymers, wherein the electrolyte is substantially free of small cations.
