ABSTRACT:
In accordance with the invention, there are systems for electronic paper, apparatus for electrophoretic display, and methods of making an electrophoretic display. The apparatus for electrophoretic can include an electret substrate and a plurality of capsules disposed in the electret substrate, wherein each of the plurality of capsules can include a first plurality of charged pigments with a first color and a first charge, a second plurality of charged pigments with a second color and a second charge greater than the first charge, a third plurality of charged pigments with a third color and a third charge greater than the second charge, and a fluid, wherein the plurality of charged pigments are subjected to a non-uniform electric field.
