Samsung - United States Patent 7,372,194 - Moon, May 13, 2008

Electron emission source composition for flat panel display and method of producing electron emission source for flat panel display using the same

Abstract

Disclosed is an electron emission source composition for a flat panel display using the same, comprising carbon nanotubes, a vehicle, and an organotitanium or an organometallic compound, and a method of producing the electron emission source composition having improved adherent strength with the substrate and providing stable and uniform electron emitting characteristics.

Inventors: Moon; Jong-Woon (Busan, KR)
Assignee: Samsung SDI Co., Ltd. (Suwon, KR)

What is claimed is:

1. A flat panel comprising: a substrate; an electrode formed on the substrate; and an electron emission source layer formed on the electrode, a surface of the layer having micro-cracks in a range of about 0.1 .mu.m to about 100 .mu.m, wherein the electron emission source layer comprises: carbon nanotubes; a vehicle; and an organotitanium crack formation compound or an organometallic crack formation compound.

2. The flat panel of claim 1, wherein the carbon nanotubes are present in a range of 5 wt % and 80 wt %, and the organotitanium crack formation compound or the organometallic crack formation compound is present in a range of 20 wt % and 95 wt %.

Kinda reminds me at first glance (!!) of a combination of SED and CNT, cracks and C nanotubes in those micro-cracks - between 0.1 and 100 mu.m across (X by 1000 to get nm).

Moon me!

Samsung rules!!
