    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： The present invention relates to a method for making an electrowetting display device comprising a plurality of picture elements and a first support plate and a second support plate. Each picture element comprises a space between the first support plate and the second support plate. The method comprises the steps of: providing the first support plate with an electrode structure; arranging an insulating layer on the electrode structure, the insulating layer having a thickness and a hydropobic surface facing the space; temporarily applying an electric field across the thickness of the insulating layer to reduce permanently the hydrophobicity of a predetermined area of the surface. The invention further relates to an electrowetting display device and a use of an area of reduced hydrophobicity in an electrowetting device.

    摘要： The present invention relates to reducing backflow in an electrowetting element for modifying a radiation beam characteristic. The electrowetting element comprises a first and a second fluid which are immiscible with each other and are switchable between a first configuration and a second configuration by application of a voltage across at least one of the first and second fluids. There is a tendency for backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration. The electrowetting element comprises a backflow reducer arranged for reducing the backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration.

    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.
