US Patent 7811667 - CNT transparent electrode with optimized conductivity and permeability

http://www.freepatentsonline.com/7811667.html

Carbon nanotubes have been proposed by a variety of different groups as future transparent electrodes for flat panel and flexible displays. This patent from Samsung teaches a configuration to optimize both the electrical conductivity and the transparency to CNT electrode films. Claim 1 reads:

1. A carbon nanotube film comprising:

a transparent substrate;

three-dimensional structures disposed apart from each other on the transparent substrate; and

carbon nanotubes disposed on the transparent substrate where the three-dimensional structures are not disposed, wherein carbon nanotubes are not disposed on the surface of the three-dimensional structures.
