US Patent 8062697 - Inkjet fabrication of CNT field emitters


This patent from Applied Nanotech has priority going back to 2001 and includes some broad claims for forming field emission displays using inkjet deposition of carbon nanotube materials. Claim 1 reads:

1. A method for making a field emission cathode comprising the step of

selectively depositing a field emitter mixture onto a substrate using an ink jet dispenser,

wherein the field emitter mixture further comprises carbon nanotubes and other nanoparticles comprising other forms of carbon.
