Abstract
A light-transmissive substrate having an inner surface, an outer surface opposite the inner surface, and a plurality of through holes. When coupled with a light-transmissive conductive material; such as indium tin oxide (ITO), the substrate provides electrical connections between a light-transmissive electrically-conductive layer, which may be used as a top electrode in an electro-optic display, and contact spots on the outer surface of the light-transmissive substrate. Accordingly, the light-transmissive substrate allows for simpler electrical connections for electro-optic displays, especially for large format devices that may need to be cut or assembled in the field. Additionally, the redundancy of having tens to hundreds of electrical contacts minimizes the chance that a device will be rendered inoperable due to a broken electrical connection.
