Abstract: n electro-optic assembly includes a layer of electro-optic material configured to switch optical states upon application of an electric field and an anisotropically conductive layer having one or more moisture-resistive polymers and a conductive material, the moisture-resistive polymer having a WVTR less than 5 g/(m2*d).

Abstract: An electro-optic medium is disclosed including a continuous phase comprising a binder and a discontinuous phase comprising electro-optic material. The binder may include one or more elastomers having a Young's modulus less than 25 MPa. The electro-optic material may include capsules that encapsulate various kinds of materials capable of switching optical states, such as a plurality of charged particles dispersed in a suspending fluid and capable of moving upon application of an electric field to the suspending fluid. The electro-optic medium may be incorporated into a laminated flexible electro-optic display having an outer light-transmissive protective layer and conductive material on either side of the electro-optic medium. The conductive material on at least one side of the electro-optic medium may also be light-transmissive. The opposing side of the display relative to the outer protective layer may also include a substrate.

Abstract: An electrophoretic display (100) comprises an electrophoretic medium (114) having electrically charged particles disposed in a fluid and capable of moving through the fluid on application of an electric field. An electrode (104, 120) is disposed adjacent the electrophoretic medium and arranged to apply an electric field thereto. A dielectric layer (106, 118) is disposed between the electrophoretic medium (114) and the electrode (104, 120) and has at least one aperture (107, 119) extending therethrough. The provision of the apertures (107, 119) in the dielectric layers enables the dielectric layers (106, 118) to protect the electrodes (104, 120) while reducing electro-optical kickback. When multiple electrodes (104, 120) are present adjacent the electrophoretic medium (114), more than one or all of the electrodes (104, 120) may be provided with apertured dielectric layers (106, 118).
