A front plane laminate useful in the manufacture of electro-optic displays comprises, in order, a light-transmissive electrically-conductive layer, a layer of an electro-optic medium in electrical contact with the electrically-conductive layer, an adhesive layer and a release sheet. This front plane laminate can be prepared as a continuous web, cut to size, the release sheet removed and the laminate laminated to a backplane to form a display. Methods for providing conductive vias through the electro-optic medium and for testing the front plane laminate are also described.

Components and methods for use in 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.

The invention relates to electro-optic displays and methods for driving such displays. The invention provides (i) electrochromic displays with solid charge transport layers; (ii) apparatus and methods for improving the contrast and reducing the cost of electrochromic displays; (iii) apparatus and methods for sealing electrochromic displays from the outside environment and preventing ingress of contaminants into such a display; and (iv) methods for adjusting the driving of electro-optic displays to allow for environmental and operating parameters.

Electro-optic displays, and methods for driving same

A front plane laminate (see U.S. Pat. No. 6,982,178) is produced by forming a sub-assembly comprising a lamination adhesive layer and an electro-optic layer, forming an aperture through the sub-assembly, and securing a light-transmissive electrode layer to the sub-assembly so that the electrode layer extends across the aperture. Alternatively, formation of the aperture is omitted, and the electrode layer has a tab portion extending beyond the edges of the lamination adhesive and electro-optic layers. When a front plane laminate is secured to a backplane to form an electro-optic display, a stiffening layer may be attached to either part to increase its stiffness, then removed after the lamination. An electro-optic display or front plane laminate may use an adhesive layer comprising separate layers of cross-linked and non-cross-linked adhesive.

Electro-optic displays, and materials and methods for production thereof

An electrophoretic medium consists of a plurality of discrete droplets () in a polymeric binder ('): each droplet () itself has a plurality of electrophoretic particles dispersed in a suspending fluid. An encapsulated electrophoretic display is produced by laminating the electrophoretic medium to a backplane () having at least one electrode at a temperature such that the polymeric binder (&#x2032;) flows and secures the electrophoretic medium to the backplane ().

Sub-assemblies and processes for the production of electro-optic displays

An encapsulated electrophoretic display is produced by laminating an electrophoretic medium, comprising a plurality of discrete droplets () in a polymeric binder ('), each droplet () comprising a plurality of electrophoretic particles dispersed in a suspending fluid, to a backplane () having at least one electrode at a temperature such that the polymeric binder (&#x2032;) flows and secures the electrophoretic medium to the backplane ().
