Patent number: 7843624Abstract: A first sub-assembly useful in an electro-optic display is produced by: providing an electro-optic sub-assembly comprising a layer of electro-optic medium; providing an adhesive sub-assembly comprising an adhesive layer, the adhesive layer being larger than the layer of electro-optic medium and having one or more apertures; adhering the adhesive sub-assembly to the electro-optic sub-assembly so that a part of the adhesive layer adheres to the layer of electro-optic medium but the aperture(s) are spaced from the layer of electro-optic medium. A second sub-assembly comprises a conductive layer and a layer of electro-optic medium. The conductive layer has a main section covered by the electro-optic medium, an exposed section free from the electro-optic medium, and a weak section connecting the main section and the exposed section, so that the exposed section can be manipulated to rupture the weak section, thus separating the exposed section from the main section without substantial damage.Type: GrantFiled: June 25, 2008Date of Patent: November 30, 2010Assignee: E Ink CorporationInventors: Guy M. Danner, Sandra Rifai, Valerie C. Northrop
