Abstract: An electrowetting display apparatus includes a first substrate including a first electrode that receives a gray-scale voltage and a second electrode insulated from the first electrode and receiving a reference voltage, a second substrate, a fluid layer, and a color filter. The color filter has a first thickness in an area corresponding to the first electrode and a second thickness in an area corresponding to the second electrode, and the first thickness is larger than the second thickness. Accordingly, a cell gap of the electrowetting display apparatus is reduced, and color reproducibility of the electrowetting display apparatus is improved without sacrificing brightness.

Abstract: An electrowetting element includes a surface having a display area; a first fluid and a second fluid immiscible with the first fluid; and a non-switchable color filter for further determining the display effect. A configuration of the first and second fluids is switchable, using an applied voltage, to determine a size of area that the first and second fluids adjoin the display area, which thereby determines a display effect provided by the electrowetting element. An extent of the non-switchable color filter in a plane parallel to a plane of the display area is smaller than the display area.

Abstract: An electrowetting element comprising a first support plate, a second support plate and a first and second fluid located between the first support plate and the second support plate, the second fluid immiscible with the first fluid. The first support plate comprises a wall extending along at least part of a perimeter of the electrowetting element and an electrode comprising a first electrode portion having a first electrode portion area and a second electrode portion having a second electrode portion area larger than the first electrode portion area. The first electrode portion is closer to the second support plate than the second electrode portion. The first electrode comprises a first edge portion and a second edge portion positioned further from an inner surface of a wall in a direction substantially perpendicular to the inner surface of the wall than the first edge portion.

Abstract: A display apparatus includes an electrowetting element including a non-switchable color filter, a first support plate with a surface having a first part overlapped by the non-switchable color filter and a second part not overlapped by the non-switchable color filter, and a first and second fluid. A control apparatus of the display apparatus is operable to switch the first fluid between at least a first configuration with the first fluid in contact with the first part but not substantially in contact with the second part and a second configuration with the first fluid in contact with the second part and with the first fluid being at least one of: not substantially in contact with the first part or at least partly in contact with the first part.
