ABSTRACT:
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 10−9to 10−4m, 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 10−9to 10−4m 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.
