Rear electrode structures for displays
First Claim
1. An electrode structure for electrically addressable displays, the structure comprising:
- a substrate defining at least one via;
a electrode disposed on a first side of said substrate;
a conductor disposed on a second side of said substrate, such that said electrode and said conductor are in electrical communication by way of said via; and
at least one electrophoretic display element disposed on said substrate adjacent said electrode.

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.
