PROTECTIVE ELECTRODES FOR ELECTROPHORETIC DISPLAYS

摘要

An electrophoretic display having a protective electrode that reduces the degradation of the display caused by mechanical or electrochemical action. T he electrode can include a protective layer that reduces the mechanical or electrochemical damage to a transparent conductive electrode. The protective electrode can be a vapor permeable electrode that is a reticulated electrically conductive structure, such as a metal screen or wire mesh, or a reticulated structure coated or impregnated with a conductive material. The protective electrode can include a layer that protects the display media fro m physical abrasion or removal by mechanical action, while allowing the application of an electric field to cause the display to be addressed.
