The phosphor layer % is covered on 15 200828396 nanometer = transparent conductive film 32, which is close to the edge of the anode electrode % and is spaced apart from the edge of the anode electrode 36 by the nanoporous transparent conductive film 32 to form a nano carbon tube. The bare region 32A of the transparent conductive film 32 is provided with graphite milk 38 under the exposed region 320. The anode electrode 36 includes an anode lead 360, an anode lead post 362, and an anode lead 4. Referring to Figure 3, cathode 40 includes a cathode emitter 42 and a cathode electrode 44 that provides an external electrode 440. The second end of the cathode emitter 42 is fixed to the cathode electrode 44, and the first end is fixed to a nickel tube 46 disposed on the glass stem 50. The cathode (42) 42 includes an electrical conductor - and an electron emission layer 422 formed on the surface of the electrical conductor 420. . The electron-emitting layer is similarly comprised of glass 426, and a plurality of carbon nanotubes 424 and conductive metal particles 428 dispersed in a surface-emitting electron. The cathode electrode 44 is the cathode lead post mentioned in the above manufacturing method. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the present invention are intended to be included in the scope of the following claims.
