Cold emission film cathode and flat panel display with nanocrystalline carbon film emitter

The invention relates to flat panel display terminals based on cold emission cathodes.The aim of said invention is to develop a full color processing display terminal using a cold emission cathode having high emission characteristics.The inventive cold emission film cathode comprises an insulated substrate which can be made of glass and a nanocrystalline carbon film emitter placed on it, said emitter is embodied in the form of a mono layer of grains of powder of a high temperature resistive material having a grain size ranging from 10to 10m, said grains being covered with a nanocrystalline carbon film. The inventive flat display terminal comprises flat glass plates on one of which a system of cold emission cathodes is arranged, said cathodes are embodied in a form of busbars coated with the mono layer of grains of powder of high temperature resistive material having a grain size ranging from 10to 10m which are covered with a nanocrystalline carbon film. The powdery grains are made of a material belonging to the family of silicon, diamond, silicon carbide, molybdenum, tungsten, tantalum, titanium and the alloys thereof. The plates are embodied in the form of a sheet glass.At least one grid can be arranged between cathode and the anode.Said invention allows to use a cheap glass and even polymers to produce a cathode assembly of a display terminal, in addition to the use of standard processing for sealing and vacuuming of the display terminal.
