摘要： The invention relates to a method of driving an electrowetting display device including a display element, the display element having an electrode for applying a voltage and providing a display state in response to a signal level of the voltage. The method comprises the following subsequent steps for maintaining a display state of the display element: (1) applying a first signal level (Va) during a first period (t1 t2) for the display state; (2) applying a second signal level (0) during a second period (t2-t3); and (3) applying the first signal level during a third period (t3-t4). The first period is longer than 1 ms and the first period plus the third period is longer than five times the second period.

摘要： The present invention describes a method for fabricating micro-devices comprising aluminumoxide structures without the need for an extra lithographical processing step. So, no extra mask is needed. It appears that under certain circumstances, aluminumoxide walls arise in the etching process, just above sloped walls of underlying metal structures. The fact that the walls of the metal structures are sloped, is essential here. Using the method according to the invention, aluminumoxide structures can be fabricated that are aligned exactly above the sloped walls of the metal structure. These aligned aluminumoxide structures can be used as walls in for example microfluidic channels, electrowetting displays, electrophoretic displays or field emitting displays.

摘要： A switchable optical element is described, along with a method of manufacturing such an element. The switchable optical element (1) comprises a fluid chamber (2) including immiscible first and second bodies of fluid (20, 22) disposed relative to one another along an optical axis (A) of the element (1). The second body of fluid (22) is movable in a direction away from the optical axis (A) by electro-wetting action, giving the switchable optical element (1) a changeable transmissivity along the optical axis (A). The switchable optical element (1) is suitable for use as an optical attenuator, e.g. a shutter, filter or diaphragm, and can be conveniently used in place of mechanical alternatives in applications such as cameras, laser resonant cavities, projectors and devices for scanning optical record carriers.

摘要： Display device based on layer break up or layer displacement having at least two different states, in which one of the fluids (5) e.g oil in a first state adjoins at least a first support plate (3) and in the second state the other fluid (6) at least partly adjoins the first support plate. In one embodiment a picture element corresponds to a substantially closed space and in the first state the other fluid layer substantially completely adjoins both support plates and is divided in two sub-layers. This makes it possible on the one hand to use lower voltages to make displacement occur. On the other hand this opens the opportunity to color displays.

摘要： The present invention relates to an optical element, used e.g. in an electrowetting display device comprising a number of pixels, arranged in an array. Each optical element comprises a cell filled with a polar conductive fluid (5), such as a water solution, and a non-polar fluid (6), such as an oil. The cell further comprises first and second planar electrodes (7, 10), covered with first and second hydrophobic layers (8, 11). By applying a voltage between on one hand the first fluid and on the second hand alternately the first or second electrodes (7, 10), the oil (6) is forced to migrate between the first and second hydrophobic layers (8, 11). Thus a bi-stable, energy efficient optical element is provided.

摘要： Apparatus for providing a fluid meniscus with variable configurations by means of electrowetting. A fluid chamber (5) holds two different fluids (A, B) separated by a meniscus (14) of which the edge, having different sides, is constrained by the fluid chamber. A first electrowetting electrode (2a) is arranged to act on a first side of the meniscus edge and a second electrowetting electrode (2a′) is arranged to act separately on a second side of the meniscus edge. Selected meniscus configurations can be formed by providing selected voltages to the first and second electrowetting electrodes respectively.
