Abstract
There is provided a display device, which is arranged to display a predetermined fixed image, having a pixel electrode layer comprising a plurality of pixel portions, and opaque solidified electrolyte arranged in a plurality of separated segments in ionic contact with a respective pixel portion, wherein each electrolyte segment and respective pixel portion form a pixel element. The fixed image display further comprises at least one continuous electrode layer extending across at least two rows and two columns of the pixel matrix, and is connected to the electrolyte segments of a subset of the pixel elements. Upon application of an electric potential difference between the patterned electrode layer and the pixel electrode layer, the pixel portions of the subset of the pixel elements switch color.
