Abstract
The invention is directed to a variety of designs of piezo electrophoretic displays which may be driven without connecting to a power source. The piezo-electrophoretic display comprises an electrophoretic layer, a conductor layer, and a layer of piezo material. The processes for manufacturing the piezo electrophoretic displays are also provided.
Claims12
A piezo-electrophoretic display comprising:
- (a) a first layer of piezo material sandwiched between a first conductor layer and a second conductor layer, (b) a second layer of piezo material sandwiched between a third conductor layer and a fourth conductor layer and (c) an electrophoretic layer sandwiched between the second conductor layer and the third conductor layer.
A piezo-electrophoretic display comprising:
- an electrophoretic layer sandwiched between a first conductor layer and a second conductor layer, a layer of piezo material sandwiched between a third conductor layer and a fourth conductor layer, the first conductor layer and the third conductor layer are connected, and the second conductor layer and the fourth conductor layer are connected.
A piezo-electrophoretic display comprising an electrophoretic layer sandwiched between a first conductor layer and a third conductor layer, a layer of piezo material sandwiched between a second conductor layer and the third conductor layer, wherein the first conductor layer and the second conductor layer are connected.
A piezo-electrophoretic display comprising a layer of piezo material sandwiched between a first conductor layer and a second conductor layer, and an electrophoretic layer sandwiched between the second conductor layer and a third conductor layer, wherein the first conductor layer and the third conductor layer are connected.
A piezo-electrophoretic display comprising an electrophoretic layer, a conductor layer, and a layer of piezo material, wherein the electrophoretic layer is microcup-based.
A U-shaped piezo-electrophoretic display comprising an electrophoretic layer sandwiched between a first conductor layer and a second conductor layer, and a layer of piezo material which, on one side, is in contact with the first conductor layer and the second conductor layer, and on the other side, is in contact with a third conductor layer, wherein the layer of the piezo material and the third conductor layer are folded into a U-shape.
