Printable electrode structures for displays
First Claim
1. An electrostatically addressable encapsulated electrophoretic image display comprising:
- a film including at least one capsule containing an electrophoretic suspension, said at least one capsule dispersed in a binder; and
at least one pair of electrodes, each of said at least one pair of electrodes disposed adjacent said film, said electrodes comprising printable conductive ink;
wherein application of electrostatic charge to said film modulates the optical qualities of said electrophoretic systems.

Abstract
Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.
