Flat display employing light emitting device and electron multiplier

Abstract

The present invention related to a flat display employing light emitting device and electron multiplier. A flat display of the present invention is fabricated to comprise the following three parts: an electron emission part of a flat substrate, light emitting device being arrayed at regular intervals in one side of the substrate and driven by video signal voltage, and photoelectric material being coated on the other side of the substrate; an electron multiplication part which comprises an electron multiplier for multiplying electrons emitted from the electron emission part and a power supply of high voltage D.C. to provide driving force therefor; and, a phosphor-activated luminescence part made of a glass coated with red(R), green(G) and blue(B) phosphors corresponding to the light emitting device by one-to-one in a matrix array, which activates each R, G or B phosphor to emit light by accelerating and colliding electrons passing through the electron multiplier with the phosphor-coated side of the glass.
