    • 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.
    • 基于层位移的显示装置具有位于靠近透明基板(4)的穿孔白色基板(14)。 诸如油运动的层(流体)位移导致(着色)油膜(5)以受控的方式泵送在白色基底上方。 可以独立地将三个减色器的液体泵送到分开的空间。 基于所使用的流体的颜色强度,可以获得小于25微米的流动通道厚度的良好的颜色再现性,因此包括小于200微米的子像素储存器的总像素厚度。

    • 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.
    • 光学元件技术领域本发明涉及一种光学元件, 在包括排列成阵列的多个像素的电润湿显示装置中。 每个光学元件包括填充有诸如水溶液的极性导电流体(5)和诸如油的非极性流体(6)的电池。 电池还包括用第一和第二疏水层(8,11)覆盖的第一和第二平面电极(7,10)。 通过一方面交替地施加第一和第二电极(7,10)之间的电压,迫使油(6)在第一和第二疏水层(8,11)之间迁移。 因此,提供了双稳态,高能量的光学元件。
