Abstract
A sheet in an electronic display is composed of a substrate containing an array of wire electrodes. The wire electrodes are preferably electrically connected to patterned transparent conductive electrode lines. The wire electrodes are used to carry the bulk of the current. The wire electrodes are capable of being extended away from the substrate and connected directly to the printed circuit board. The transparent conductive electrode (TCE) is used to spread the charge or voltage from the wire electrode across the pixel. It is a patterned film and must be at least 50% transparent, and, for most applications, is preferably over 90% transparent. In most display applications, the electroded surface of the electroded sheet has to be flattened. Use of a thin polymer substrate yields a light, flexible, rugged sheet that may be curved, bent or rolled.
