Screen printed carbon nanotube field emitter array for lighting source application

Photosensitive carbon nanotube (CNT) paste was synthesized with spin on glass (SOG) as inorganic binder. The field emission characteristics of this CNT paste was studied. CNT field emitter arrays (FEAs) was then fabricated using screen-printing method, photolithography and vacuum-in-line sealing technology. It is concluded that the diode type FEA using CNT paste with SOG can be used for lighting system applications such as the back light unit in TFT-LCD.
