    • A display apparatus is described comprising a plurality of electrofluidic chromatophore (EFC) pixel cells. Each pixel cell comprises a fluid holder for holding a polar fluid and a non-polar fluid having differing display properties. The fluid holder comprises a fluid reservoir with a geometry having a small visible area onto the polar fluid, and a channel with a geometry having a large visible area onto the polar fluid. The channel is connected to the reservoir to enable free movement of the polar fluid and non-polar fluid between the channel and the reservoir. At least part of a surface of the channel comprises a wetting property responsive to a supply voltage. The pixel cell comprises at least one further pixel cell terminal that is coupled to a further electrode to supply a direct voltage to the pixel cell.
    • 描述了一种显示装置,其包括多个电流体色差(EFC)像素单元。 每个像素单元包括用于保持极性流体的流体保持器和具有不同显示特性的非极性流体。 流体保持器包括具有在极性流体上具有小可见区域的几何形状的流体储存器,以及具有在极性流体上具有大的可见区域的几何形状的通道。 通道连接到储存器,以使极性流体和非极性流体在通道和储存器之间自由移动。 通道的表面的至少一部分包括响应于电源电压的润湿特性。 像素单元包括至少一个另外的像素单元端子,其耦合到另一电极以向像素单元提供直接电压。
