Conducting film or electrode with improved optical and electrical performance

Abstract

A conducting film or device electrode includes a substrate and two transparent or semitransparent conductive layers separated by a transparent or semitransparent intervening layer. The intervening layer includes electrically conductive pathways between the first and second conductive layers to help reduce interfacial reflections occurring between particular layers in devices incorporating the conducting film or electrode.

1 . A transparent or semitransparent conducting article comprising:
 a first electrically conductive layer;   a second electrically conductive layer; and   an intervening layer disposed between the first and second electrically conductive layers, the intervening layer defining a plurality of apertures therein, the first and second electrically conductive layers directly contacting one another through the plurality of apertures.   
     
     
         2 . The conducting article of  claim 1  being transparent. 
     
     
         3 . The conducting article of  claim 1  being semitransparent. 
     
     
         4 . The conducting article of  claim 1 , wherein the first electrically conductive layer is transparent. 
     
     
         5 . The conducting article of  claim 1 , wherein the second electrically conductive layer is transparent. 
     
     
         6 . The conducting article of  claim 1 , wherein the intervening layer comprises a dielectric. 
     
     
         7 . The conducting article of  claim 1 , wherein the intervening layer comprises a polymer. 
     
     
         8 . The conducting article of  claim 1 , wherein the intervening layer comprises an organic material. 
     
     
         9 . The conducting article of  claim 1 , wherein the intervening layer comprises an inorganic material. 
     
     
         10 . A display having a display area electronically displaying content, the display comprising a transparent electrode in the display area, the transparent electrode comprising the conducting article of  claim 1 . 
     
     
         11 . The conducting article of  claim 1  configured to function as a single electrode in a display. 
     
     
         12 . The conducting article of  claim 1  having a greater electrical conductivity than each of the first and second electrically conductive layers. 
     
     
         13 . The conducting article of  claim 1 , wherein the first and second electrically conductive layers and the intervening layer are substantially coextensive with one another. 
     
     
         14 . The conducting article of  claim 1 , wherein the intervening layer is electrically conductive.
