ABSTRACT:
A field emitting luminous device is disclosed. The device includes a cathode electron emitting unit, an electron amplifying unit, a panel unit, and an electric power supply unit. The primary electrons emitted from the cathode electron emitting unit hit the electron amplifying material on the electrode surface of the electron amplifying unit, generating amplified secondary electrons. The secondary electrons bombard the light-emitting layer of the panel unit, producing fluorescence. The fluorescence penetrates the upper transparent panel and is thus observed by eyes.
