Claims
- 1. An electrophoretic display comprising:a substrate; at least one capsule containing a suspending fluid and at least one charged particle, said charged particle having an optical property; and at least two electrodes disposed on said substrate adjacent said at least one capsule and positioned in a spaced apart relationship to one another, wherein a potential difference between said electrodes causes the particles to migrate toward at least one of said at least two electrodes, thereby effecting change in visual state.
- 2. The display of claim 1, wherein said suspending fluid is substantially transparent.
- 3. The display of claim 1, wherein said at least one charged particle has a black color.
- 4. The display of claim 1, wherein said at least one charged particle has a white color.
- 5. The display of claim 1, wherein one of said at least two electrodes is substantially transparent.
- 6. The display of claim 1, wherein both of said at least two electrodes are substantially transparent.
- 7. The display of claim 1, wherein one of said at least two electrodes has a first optical property and the other of said at least two electrodes has a second optical property.
- 8. The display of claim 7, wherein said at least one charged particle is black and wherein application of a first voltage potential to a black electrode causes said black particles to migrate within said capsule to a location adjacent said black electrode, causing said capsule to appear substantially white, and wherein application of a second voltage potential to said black electrode causes said black particles to migrate within said capsule to a location adjacent said white electrode causing said capsule to appear substantially black.
- 9. An electrophoretic display comprising:at least one capsule containing a suspending fluid and at least one particle having a first optical property; at least two electrodes, each having a second optical property adjacent said at least one capsule; and at least one electrode having said first optical property adjacent said at least one capsule; wherein application of a voltage potential to said at least two electrodes causes the capsule to change visual state.
- 10. The electrophoretic display of claim 9, wherein each of said at least two electrodes has a different optical property.
- 11. The electrophoretic display of claim 9, wherein said suspending fluid is dyed.
- 12. The electrophoretic display of claims 9, wherein said suspending fluid is substantially transparent.
- 13. The electrophoretic display of claim 9, wherein said at least one particle has a black color.
- 14. The electrophoretic display of claim 9, wherein said at least one electrode is substantially transparent.
