Abstract: An electrowetting display device comprising a first fluid; a second fluid immiscible with the first fluid; a first support plate having: a surface adjoined by at least one of the first or second fluids, and a first electrode. The device further comprises a second support plate; a second electrode in electrical contact with the second fluid; and a third electrode. The device comprises a protrusion formed as part of at least one of the first support plate or the second support plate. The protrusion has an elongate shape extending from one to the other of the first or second support plates. The protrusion comprises a protrusion surface formed of a material which, without a voltage applied, is less wettable for the first fluid than the surface of the first support plate.

Abstract: A display apparatus comprises an electrowetting picture element with a first support plate with a first support plate portion comprising a layer substantially non-transmissive for light and second support plate portion substantially non-absorbing for light. A display controller is configured to control a display effect of the electrowetting picture element between a dark and light display effect, and, responsive to input data corresponding to the dark display effect, output at least one signal to a driver corresponding to the dark display effect. The driver is configured to, responsive to the at least one signal output by the display controller, apply a first, non-zero, voltage to the electrowetting picture element to switch a first and a second fluid of the electrowetting picture element to a first configuration with the first fluid and the second fluid in contact with a first surface of the first support plate portion and the first fluid in contact with a second surface of the second support plate portion.
