An experimental dismountable high-voltage field-emission display has been fabricated. It is used to demonstrate that gated structures may be adapted to the case where flat-film emitters are made of a carbon-nanotube-epoxy composite. Experiments have been carried out to study the field electron emission characteristics of the display unit and to optimize the structural parameters. Our findings indicate that it is very likely for one to produce a near-market prototype high-voltage field-emission display, if a more sophisticated fabrication and assembly technique is adapted.
