Abstract
A matrix driven electrophoretic display with a multi-layer back plane is disclosed. The display comprises a top electrode layer, a display cell layer, and a multi-layer back plane. In one embodiment, the multi-layer back plane comprises an electrode formed on the top surface of the top substrate of the multi-layer back plane, a conductive via structure through the substrate, and a conductive trace connected electrically to the via structure at the bottom surface of the first substrate, whereby an electrical connection may be made from the electrode to a structure or component not located immediately beneath the electrode in the multi-layer back plane. In other embodiments, the multi-layer back plane may comprise additional layers and via holes, as needed to connect the electrode with the appropriate switching elements and/or driver elements, as applicable. Such switching and driver elements, integrated with multi-layer back plane.
