Abstract

The invention provides an electrophoretic medium comprising at least two types of particles having substantially the same electrophoretic mobility but differing colors. The invention also provides article of manufacture comprising a layer of a solid electro-optic medium, a first adhesive layer on one surface of the electro-optic medium, a release sheet covering the first adhesive layer, and a second adhesive layer on an opposed second surface of the electro-optic medium.

First claim

The invention claimed is:

1. An electro-optic display comprising:
an electrophoretic medium comprising a suspending fluid, a plurality of electrically charged particles suspended in the suspending fluid and capable of moving therethrough on application of an electric field to the suspending fluid, a plurality of capsules, each capsule having a capsule wall surrounding the suspending fluid and the electrically charged particles, and a binder surrounding the capsules;
a lamination adhesive disposed adjacent the electrophoretic medium;
an addressing electrode to address the electrophoretic medium; and
a front electrode disposed between the electrophoretic medium and a viewing surface of the display, and
wherein the electrophoretic medium is between the addressing electrode and the front electrode, and
wherein at least one of the capsule wall of the plurality of capsules, the binder, the lamination adhesive, and the front electrode is tinted to form a color filter array.
