1. A process for forming an electro-optic display comprising:
- providing a backplane comprising at least one pixel electrode;
providing a front sub-assembly comprising, in order, an adhesive layer, a layer of electro-optic material and at least one support layer, the support layer being larger than the layer of electro-optic material and the adhesive layer so as to leave a peripheral area of the support layer exposed around the layer of electro-optic material;
dispensing a curable material on to one of the backplane and the peripheral area of the support member, and curing the curable material to form a dam member;
laminating the adhesive layer of the front sub-assembly to the backplane, andthereby causing the dam member to extend between the backplane and the peripheral area of the support layer; and
dispensing a sealing material adjacent the dam member to form a seal extending between the backplane and the peripheral area of the support layer.

Abstract
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.

7. A method of testing an electro-optic medium, the method comprising:
-
disposing a layer of the electro-optic medium on a light-transmissive first electrically-conductive layer; disposing a second electrically-conductive layer on the opposed side of the layer of electro-optic medium from the first electrically-conductive layer; applying a potential difference between the first and second electrically-conductive layers, thereby forming an image on the medium; and observing the image thus formed. - View Dependent Claims (8, 9, 10, 11)

12. A method of testing an electro-optic medium, the method comprising:
-
disposing a layer of the electro-optic medium on a light-transmissive electrically-conductive layer; disposing a release on the opposed side of the layer of electro-optic medium from the electrically-conductive layer; placing an electrostatic charge on the release sheet, thereby forming an image on the medium; and observing the image thus formed. - View Dependent Claims (13, 14, 15, 16)
