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.
