Characterization of triode‐type CNT‐FED fabricated using Photo‐sensitive CNT Paste

Abstract A carbon nanotube field emission display (CNT FED) panel with a 2 inch diagonal size was fabricated through screen printing of a prepared photo‐sensitive CNT paste and vacuum in‐line sealing technology. After surface treatment of the patterned CNT, only the carbon nanotube tips are uniformly exposed on the surface. The diameter of the exposed CNTs are usually about 20nm. The sealing temperature of the panel is around 390 °C and the vacuum level is obtained with 1.4×10−5torr at the sealing. The field emission properties of the diode type CNT FED panel are characterized. Currently, we are in the process of developing a triode type CNT FED with a self‐aligned gate‐emitter structure.
