Abstract

Claims (7)

1. A patterned substrate comprising:

a visible light transparent substrate; and

a plurality of spaced apart substantially parallel electrically conductive mesh bars disposed on or in the visible light transparent substrate, each mesh bar comprising a plurality of first traces having a first width and defining a plurality of enclosed open areas, the mesh bar electrically connected to an electrically conductive second trace, the second trace comprising a first portion extending laterally across the mesh bar and making contact with the first traces of the mesh bar and a second portion having a second width greater than the first width and extending from the first portion to an electrically conductive pad for making electrical contact with an electronic device, wherein the mesh bar and the first portion of the second trace include a same metal at approximately a same thickness.

2. The patterned substrate of claim 1 , wherein for each mesh bar, the first width of the first traces is less than or equal to 10 micrometers.

3. The patterned substrate of claim 1 , wherein each mesh bar comprises random cell shapes, irregular polygons, or a combination thereof.

4. The patterned substrate of claim 1 , wherein the electrically conductive pad is not transparent and has a width between 25 micrometers and 1 mm, and wherein the mesh bar and the conductive pad include the metal at approximately a same thickness.

5. The patterned substrate of claim 1 , wherein the mesh has an open area between 90 and 99.5 percent.
