COMPONENTS AND TESTING METHODS FOR USE IN THE PRODUCTION OF ELECTRO-OPTIC DISPLAYS
First Claim
1. A method for testing a laminate comprising a layer of a solid electro-optic medium having two extreme optical states, and an electrically conductive layer, the method comprising:
- passing the laminate over a pair of electrodes maintained at different potentials, the laminate being passed over the electrodes such that during this passage the electrically conductive layer lies on the opposed side of the layer of electro-optic medium from the electrodes, the potential difference between the pair of electrodes being maintained large enough to switch a surface of the electro-optic medium substantially to one of its extreme optical states.

Abstract
A laminate comprising a solid electro-optic medium and an electrically conductive layer is tested by passing it over a pair of electrodes at different potentials, with the electrically conductive layer lying on the opposed side of the electro-optic medium from the electrodes. An article which can be tested by this method, and which is useful in the manufacture of electro-optic displays, comprises a layer of a solid electro-optic medium and a release sheet comprising an electrically conductive layer.
