摘要： A transflective display device has a viewing side (7) and a rear side (8) and comprises a plurality of electrowetting elements (2) having a first support plate (5) facing the viewing side and a second support plate (6) facing the rear side. Each electrowetting element comprises a space (10) between the first support plate and the second support plate and includes a first fluid (11) and a second fluid (12) immiscible with each other. The second fluid absorbs at least a part of the optical spectrum. The position of the second fluid is controllable to cover a predetermined area (30) of the cross-section (29) of the space in the plane of the second support plate. A structured reflector (18) is arranged on the second support plate, comprising within the cross-section an area (33, 34) transparent for light incident from the rear side and an area (35, 36) reflective for light incident from the viewing side. The transparent area and the reflective area are arranged such that the predetermined area (30) covered by the second fluid covers the same proportion of the transparent area and the reflective area.

摘要： An electrowetting display device comprises a plurality of picture elements (2) having a first support plate (5) including a surface (68) and a second support plate. A space (10) of a picture element between the surface of the first support plate and the second support plate includes at least one first fluid and a second fluid immiscible with each other, the second fluid being electroconductive or polar. The first support plate includes an electrode (46) for applying an electric field in the picture element. It also includes a layer (44) arranged on a side of the electrode facing away from said space. The layer forms an electronic component (33) for applying a voltage to the electrode. The electrode comprises a height difference (86) corresponding to a thickness of the layer (44). The height difference causes an inhomogeneous electric field in the space, providing a preferred direction of motion of the first fluid on application of the electric field.

摘要： A pixel cell in an active matrix display comprising a current driven emissive element such as an OLED (20) and a data input (17) for receiving an analogue data signal (Vin). The pixel has at least two drive elements (12, 14), each being connected to a power supply (16) and arranged to drive the emissive element in accordance with the data signal, and selecting means (22, 24) for providing, in response to a select signal (21, 23), the data signal to at least one of the drive elements (12, 14). Further, each drive element is adapted to drive the emissive element (20) in a different drive current range in response to a given data signal. Thereby, a required brightness range can be obtained while data voltages too close to the threshold voltage may be avoided.
