ABSTRACT:
An electrocapillary color display sheet is disclosed which utilizes a plurality of sets of different color droplets between two sheets in which each set of droplets will create a pixel of an image. Each set of droplets has at least two droplets in which each droplet has a different color. Each droplet of each set is immiscible with the rest of the droplets of the set. There is an electrode on each sheet which corresponds to each set of droplets. There is also an addressable electrical connection to each droplet. By selectively activating droplets of each set of droplets and its corresponding electrodes on the two sheets, at least one of the droplets of the set will expand in a space commonly shared by the droplets of each set to create a colored pixel.
