An electrochromic display device comprising a set of pixel cells, each pixel cell being arranged to display at least one symbol, which at least one symbol is repeatedly switchable between an on-state and an off-state, which on-state and off-state have two different visually detectable colouring states, wherein each pixel cell comprises: a first layer comprising electrochromic and electrochemically active organic polymer material being electrochemically switchable between said two different visually detectable colouring states, a counter electrode comprising an electrically conductive material an electrolyte layer, which electrolyte is arranged spatially between, and in ionic contact with, said first layer and said counter electrode, a symbol defining layer which is electronically and ionically insulating arranged in direct contact with said first layer, and which symbol defining layer comprises one or more openings defining the shape of said symbol, wherein said electrolyte layer fills said openings of said symbol defining layer, a pair of connectors (57, 58), each connector in electronic contact with a respective one of said first layer and said counter electrode, wherein said counter electrodes of said set of pixel cells are electrically separated from each other, and the device further comprises: a circuitry in electronic contact with each connector in said pair of connectors of each pixel cell of said set of pixel cells, which circuitry is configured to be connected to a power supply, and which circuitry is further configured to selectively provide a respective potential difference between said pair of connectors of each pixel cell in said set of pixel cells at least when connected to said power supply, wherein said circuitry is further configured to detect a change in capacitance in at least one pixel cell of said set of pixel cells, said change in capacitance being caused by an external object in close proximity to said at least one pixel cell, and switch a subset of pixel cells of said set of pixel cells between one of said on-state and said off-state and the other of said on-state and said off-state, in response to said change in capacitance exceeding a predetermined threshold, by providing said respective potential difference between each one of said pair of connectors of said subset of pixel cells. a first layer comprising
