The present invention provides an electron amplification plate placed between a first substrate and a second substrate of a field emission display device. The electron amplification plate comprises at least two insulating layers for electrical insulation; and at least one conductive electrode layer having plural apertures, wherein the conductive electrode layer is sandwiched between the insulating layers. The surface of the inner wall of the apertures is coated with an electron-amplifying material for multiplying the quantity of electrons as the surface is impacted. The inner wall of each aperture comprises an upper concave wall and a lower concave wall, and the lower concave wall is used for collecting electrons, and the upper concave wall is used for focusing electrons. Thereby, the electron beam emitted from the emitters can be effectively amplified, and color purity of the field emission display device is high.

Electron amplification plate for field emission display device

A field emission display device includes three parts: a cathode emitter unit, an electron amplification unit, and a faceplate unit. The primary emission of electrons emitted from the cathode emitter unit bombards an electrode layer that includes an electron amplification material in order to generate secondary emissions of electrons. The secondary emissions of electrons bombard a light-emitting layer of the faceplate unit to generate fluorescence. Then, the fluorescence is transmitted through a transparent faceplate for viewing.

Field emission display device

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.
