Abstract
An electrowetting display device comprising an electrowetting element comprising a control system, a first fluid, a second fluid immiscible with the first fluid, and a first and second support plate. A first and second electrode are, respectively, overlapped by a first and second portion of a surface of the first support plate. The control system is operable to, in response to input data indicative of a first grey level, apply a first voltage between the second fluid and the first electrode such that the second fluid is in contact with at least part of the first portion and, subsequently, apply a second voltage between the second fluid and the second electrode to translate the first fluid such that the second fluid is in contact with at least part of the second portion.
