Abstract:
1. A display device comprising picture elements separated by picture walls, each picture element having at least a first fluid and a second fluid immiscible with each other within a space between a first support plate and a second support plate, the second fluid being electroconductive or polar, the picture elements each comprising at least one barrier separating the picture element to define sub-picture elements, the display device further comprising electrodes separated from each other along the barriers to provide an electrode for each sub-picture element, the barriers during operation allowing transfer of the first fluid within the picture element between a first sub-picture element and a second sub-picture element for moving the first fluid across the barrier away from a first picture area controlled by a first electrode of the first sub-picture element, to a second picture area controlled by a second electrode of the second sub-picture element.
