Abstract
An electrophoretic display unit includes a substrate, a first electrode, a first insulation layer, a second electrode and a second insulation layer. The first electrode is disposed on the substrate. The first insulation layer is disposed on the first electrode. The second electrode is disposed on the first insulation layer. The second insulation layer is disposed on the second electrode. Wherein, the second insulation layer has an opening for appearing a part of the second electrode.
Claims8
An electrophoretic display unit comprising:
- a substrate;
- a first electrode disposed on the substrate;
- a first insulation layer disposed on the first electrode;
- at least a second electrode disposed on the first insulation layer;
- a second insulation layer disposed on the second electrode, wherein the second insulation layer has an opening for appearing a part of the second electrode, so that the at least second electrode acts as at least a side electrode, and the at least second electrode is disposed at the middle of a side wall of the opening;
- wherein a depth of the opening is greater than a depth of the second insulation layer;
- and
- a third electrode disposed on the second insulation layer, wherein the third electrode, the first electrode and the at least second electrode are used for controlling the motion of electrophoretic particles within the opening.
