1. A touch screen comprising:

  • a substrate;

    a patterned cathode layer including a plurality of cathode layer segments, including a first cathode layer segment, a second cathode layer segment, and a third cathode layer segment;

    a first encapsulation layer having an overlaying portion overlaying one or more of the plurality of cathode layer segments and a portion disposed between adjacent cathode layer segments, the first encapsulation layer including a first via at a location of the first cathode layer segment and a second via at a location of the second cathode layer segment, wherein;

    the third cathode layer segment is between the first cathode layer segment and the second cathode layer segment in the patterned cathode layer, andthe third cathode layer segment is electrically isolated from the first cathode layer segment and the second cathode layer segment; and

    a conductive connection having an overlaying portion overlaying the first encapsulation layer, a first connection portion connected to the first cathode layer segment, and a second connection portion connected to the second cathode layer segment, wherein;

    the patterned cathode layer is between the substrate and the overlaying portion of the first encapsulation layer.
