Improved electro-optic devices are disclosed comprising an electrophoretic material layer comprising electrophoretic medium disposed between electrodes, and a conductive edge seal. The conductive edge seal is not only used to prevent ingress of moisture in the device, but also to electrically connect the electrodes. An improved method of producing an electro-optic device having conductive edge seal is also disclosed.

An electrical connection between the backplane and the light-transmissive front electrode of an electrowetting device is provided by forming an aperture through the top front electrode coupled and a substrate coupled thereto and subsequently introducing a flowable, electrically-conductive material into the aperture. The flowable, electrically-conductive material provides an electrical contact between the light-transmissive electrically-conductive layer and the backplane.

Method of forming a top plane connection in an electro-optic device

Methods of making a top-plane connection in an electro-optic device and devices including such connections. A through hole is created through a rear substrate to provide a connection between a conductor coupled to the rear substrate and a light-transmissive conductive layer coupled to a top transparent substrate. The hole is subsequently filled with a top-plane connection material that provides an electrical connection between the conductor and the light-transmissive conductive layer, but does not provide an electrical connection between a separate rear conductive layer and the light-transmissive conductor.

An electrical connection between the backplane and the light-transmissive front electrode of an electro-optic display is provided by forming an aperture through the top front electrode coupled and a substrate coupled thereto and subsequently introducing a flowable, electrically-conductive material into the aperture. The flowable, electrically-conductive material provides an electrical contact between the light-transmissive electrically-conductive layer and the backplane.

A method of forming an electrophoretic display is provided that includes forming a front plane laminate having a first substrate, a first conductive layer, a layer of electrophoretic media, and an adhesive, as well as coating an insulating layer and a second conductive layer onto a second substrate to provide a backplane. The first substrate and first conductive layer may be transparent, and the second substrate may include a plurality of conductors. The method may further include scoring the second substrate to provide a removable portion, laminating the front plane laminate to the backplane, removing the portion from the second substrate to provide an opening in the backplane, and filling the opening with a conductive material to provide an electrical connection between the first conductive layer and one of the plurality of conductors. Electrophoretic displays made according to the various methods are also provided.

Processes for the production of electro-optic displays

A display assembly comprises a backplane assembly comprising a plurality of spaced backplane areas, each backplane area comprising a plurality of electrodes, the backplane areas being separated by gutter areas free from electrodes; an adhesive layer overlying the plurality of spaced backplane areas; and a layer of a solid electro-optic medium overlying the adhesive layer in the plurality of spaced backplane areas. The display sub-assembly can be produced via a single lamination and severed to form a plurality of separate electro-optic displays. Processes for producing the display assembly are also described.

Components and methods for use in electro-optic displays

A multi-layer film (), useful as a barrier film in electro-optic displays, comprises a light-transmissive adhesive layer (), a light-transmissive first protective layer (), a light-transmissive first moisture barrier layer (B), an intermediate layer (typically an adhesive layer) (), a light-transmissive second moisture barrier layer (A) and a light-transmissive second protective layer (). The second protective layer may be covered by a hard coat () and/or a masking film ().
