摘要： An optical element used, e.g., in an electrowetting display device having a number of pixels, is arranged in an array. Each optical element includes a cell filled with a polar conductive fluid, such as a water solution, and a non-polar fluid, such as an oil. The cell further includes first and second planar electrodes covered with first and second hydrophobic layers. By applying a voltage between the first fluid and alternately the first or second electrodes, the oil is forced to migrate between the first and second hydrophobic layers. Thus a bi-stable, energy efficient optical element is provided.

摘要： An exemplary display device based on layer displacement having a perforated white substrate positioned close to a transparent substrate. Layer (fluid) displacement such as oil movement results in the (colored) oil film 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.
