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.

摘要: Switching between 2D and 3D visualization is achieved by an optical-index matching fluid (9) which can be brought between a lenticular sheet (6, 7) and a top plate (10). The fluid may contain two immiscible fluids while switching is based on (re)distribution of the fluids due to electrostatic forces.

摘要: Optical apparatus for a display device. The optical apparatus comprises a cavity, and a first fluid (14) and a second fluid (16), held within the cavity, which are immiscible with each other. The first and second fluids are separated from each other by a meniscus (28) having a peripheral edge (30). The optical apparatus further comprises a fluid motion control system arranged to control movement of the first and second fluids within the cavity using electrostatic forces, and a first surface (26) and a second surface (21). The first surface has a different wettability for the first fluid than for the second surface. The first and second surfaces are arranged in the cavity to determine, upon activation of the fluid motion control system, a motion of the fluids within the cavity which has a preferential initiation at a first part (32) of the peripheral edge.

摘要: Display device is based on layer break up or layer displacement having at least two different states, in which one of the fluids, e.g., oil in a first state, adjoins at least a first support plate and, in the second state, the other fluid 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.
