Application of carbon nanotubes to field emission displays

Large-area field emission displays were fabricated with single-wall carbon nanotube emitters. A carbon nanotube paste was prepared and screen-printed to form an electron emission layer on a glass-based substrate. Carbon nanotube-based field emission displays fabricated by thick him processing were successfully integrated to demonstrate moving color images. They revealed excellent Add emission characteristics of a threshold electric field of approximately 2 V/mum. We have also investigated triode-type field emission display structures to achieve high-gray scale and high brightness. In the triode structure, it was observed that electron emission from carbon nanotube emitters was controlled by modulation of gate voltages. (C) 2001 Published by Elsevier Science B.V.
