Electro-wetting display apparatus

摘要

An electro-wetting display apparatus includes a first base substrate, a plurality of first electrodes on the first base substrate, an insulating layer which overlaps the first electrodes, a pixel wall on the insulating layer, where the pixel wall partitions a plurality of pixels respectively corresponding to the plurality of first electrodes, a second base substrate which face the first base substrate, a second electrode on the second base substrate and including a plurality of openings, and a fluid between the first base substrate and the second base substrate and in the plurality of pixels. The movement of the fluid in the plurality of pixels is controlled by voltages respectively applied to the first electrodes and the second electrode.

1. An electro-wetting display apparatus comprising:
a first substrate; a plurality of first electrodes disposed on the first substrate; a hydrophobic surface disposed on the plurality of first electrodes; pixel walls disposed on the hydrophobic surface, wherein the pixel walls intersect to partition a plurality of pixels, wherein the plurality of pixels respectively corresponds to the plurality of first electrodes such that each pixel includes a corresponding first electrode, and wherein each corresponding first electrode is spaced from at least one pixel wall to define a region within the pixel that includes the corresponding first electrode; a second substrate that faces the first substrate; a second electrode disposed on the second substrate; and a first fluid disposed on a second fluid, wherein the second fluid is disposed on the hydrophobic surface and is substantially immiscible with the first fluid, and wherein the first fluid and the second fluid are disposed in each of the pixels of the plurality of pixels between the first substrate and the second substrate, wherein displacement of the second fluid on the hydrophobic surface to the regions in the plurality of pixels, such that the first fluid replaces the second fluid on a portion of the hydrophobic surface, is controlled by voltages that are respectively applied to the plurality of first electrodes and the second electrode.
