US Patent 7294372 - Carbon nanotubes for color filter

http://www.freepatentsonline.com/7294372.html

Conductive color filters are useful in display applications to provide conductive paths to control circuitry while regulating the colors of display pixels. This patent from Kodak discloses the use of carbon nanotubes with a resin colorant to construct such filters. Claim 1 reads:

1. An array of electrically connected conductive color filters, wherein each conductive color filter is in electrical contact with a transparent conductive electrode, at least one conductive color filter comprising an unpatterned layer of carbon nanotubes covered by a patterned layer of colored polymeric resin binder, wherein the color of the colored polymeric binder is black, red, green or blue.
