Abstract
Abstract An image capture panel includes a substrate layer of dielectric material having a top surface and a bottom surface. A plurality of sensors is arrayed in a matrix of rows and columns adjacent the top surface of the substrate layer. Each of the sensors has a switching device and a sensing element. A portion of the sensing element are really covers the switching device so as to be substantially coextensive therewith. Prefereably, the sensing element also extends over at least a part of the horizontal spacing and/or the vertical spacing which separates, respectively, each row of sensors and each column of sensors.
