摘要: Display device based on layer displacement having a perforated white substrate (14) positioned close to a transparent substrate (4). Layer (fluid) displacement such as oil movement results in the (colored) oil film (5) being pumped in a controlled manner above the white substrate. Fluids of three subtractive colors can be independently pumped to separate spaces. Based on the color strength of the used fluids good color rendition can be obtained for a flow channel thickness of less than 25 microns and therefore a total pixel thickness including the sub pixel reservoirs of less than 200 microns.

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: 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.
