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 nanot ube-based field emission displays fabricated by thick him processing were s uccessfully integrated to demonstrate moving color images. They revealed ex cellent Add emission characteristics of a threshold electric field of appro ximately 2 V/mum. We have also investigated triode-type field emission disp lay structures to achieve high-gray scale and high brightness. In the triod e structure, it was observed that electron emission from carbon nanotube em itters was controlled by modulation of gate voltages. (C) 2001 Published by Elsevier Science B.V.
