US Patent 7741232 - Electron emitting nanofabric

http://www.freepatentsonline.com/7741232.html

In order to form large area electronic displays from plastic or flexible material new manufacturing techniques will need to be developed. This patent from Ideal Star Inc. teaches using woven fabrics as an alternative to planar deposition manufacturing for developing wide area field emission material for displays. Claim 1 reads:

1. An electron-emitting woven fabric comprising:

first linear bodies having a conductive layer covered with an insulating layer; and

second linear bodies formed of a conductive material and crossing the first linear bodies to form cross parts, wherein the conductive layer comprises a conductive polymer,

a carbonaceous material is provided on a surface of the second linear bodies of the cross parts, the carbonaceous material is one or more selected from a group consisting of carbon nanotubes and fullerenes, and electrons are emitted from the cross parts of the first linear bodies and the second linear bodies.
