Abstract:
A cathodoluminescent display device, which comprises:a faceplate through which emitted light is transmitted from an inside surface to an outside surface of the faceplate for viewing;a cathode electron emitter, for primary field emissions of electrons, where said cathode electron emitter comprises a radioactive material of an amorphous silicon film formed using tritium doped silane that decays to provide a source of primary electron emissions with which the display device is activated;an anode, comprising a layer of electrically conductive material disposed between the inside surface of the faceplate and the cathode electron emitter; anda light emitter layer of cathodoluminescent material capable of emitting light through the faceplate in response to bombardment by electrons emitted within the device, disposed between the anode and the cathode emitter.
