Abstract
An optical switch, e.g. a display cell based on layer displacement or layer break up having at least two different states, in which one of the fluids e.g. oil in a first state adjoins at least a first support plate and in the second state the other fluid at least partly adjoins the first support plate. Part of an otherwise homogeneous electrode is removed to realize oil motion control.
Claims13
A display device comprising:
- a first support plate;
- an opposing second support plate;
- and
- picture elements disposed between the first and second support plates, each picture element comprising:
- a wall enclosing first and second regions of a surface of the first support plate, the first and second regions being non-overlapping;
- a first fluid and a second fluid immiscible with each other disposed within a space between the first support plate, the second support plate, and the wall, the second fluid being electroconductive or polar, and the first fluid being confined within the wall;
- and
- a first electrode arranged on the first support plate in the first region only and configured to apply an electro-wetting effect, such that the first fluid forms a continuous film covering the first region and the second region when no voltage is applied to the first electrode, and the first fluid moves toward the second region on application of a voltage to the first electrode.
