ELECTRO-OPTIC DISPLAYS, AND MATERIALS AND METHODS FOR PRODUCTION THEREOF
First Claim
1. An article of manufacture for use in the production of an electro-optic display, the article comprising a conductive layer and a layer of electro-optic medium, the conductive layer having a main section covered by the layer of electro-optic medium, an exposed section in at least part of which the conductive layer is exposed free from the electro-optic medium, and a weak section connecting the main section and the exposed section, such that the exposed section can be manipulated to cause rupture of the weak section, thereby separating the exposed section from the main section without substantial damage to the main section.

Abstract
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.

- 1. An article of manufacture for use in the production of an electro-optic display, the article comprising a conductive layer and a layer of electro-optic medium, the conductive layer having a main section covered by the layer of electro-optic medium, an exposed section in at least part of which the conductive layer is exposed free from the electro-optic medium, and a weak section connecting the main section and the exposed section, such that the exposed section can be manipulated to cause rupture of the weak section, thereby separating the exposed section from the main section without substantial damage to the main section.

12. A process for testing a layer of electro-optic medium, the process comprising:
-
providing an article comprising a conductive layer and a layer of electro-optic medium, the conductive layer having a main section covered by the layer of electro-optic medium, an exposed section in at least part of which the conductive layer is exposed free from the electro-optic medium, and a weak section connecting the main section and the exposed section; applying a potential to the conductive layer sufficient to change the optical state of the layer of electro-optic medium; observing the appearance of the layer of electro-optic medium following the change; and thereafter, manipulating the exposed section to cause rupture of the weak section, thereby separating the exposed section from the main section without substantial damage to the main section.

13. A process according to claim 30 wherein the article comprises first and second conductive layers disposed on opposed sides of the layer of electro-optic medium, each of the first and second conductive layers being provided with an exposed section and a weak section, the potential is applied between the first and second conductive layers, and thereafter both exposed sections are manipulated to cause rupture of both weak sections.
