[Technical Field] The present invention relates to an electronic method in which a solution is homogenized by a spraying technique to form a coating layer, and when the film is removed by a film stripping device, the strength of the material is in the film removing process. The middle can be applied to large-sized panels, and wide. A method for activating the surface of an emissive source, in particular, a surface of each of the transfer layers of the cathode structure is coated with a film of adhesive, and the coating layer is removed, since the coating of the winning film is not damaged or broken, Will be more suitable for the material using the overlay layer [Prior Art] "The three-pole field emission display of the known structure" mainly includes an anode structure / a cathode structure, and a support pacer is disposed between the anode structure and the cathode structure, Provided as a gap between the anode structure and the vacuum region between the cathode structures, ^ = a support between the anode structure and the cathode structure, the anode structure comprising an anode substrate, an anode conductive layer and a phosphor powder layer (ph〇sph〇) Rs丄吖^); the cathode structure comprises a cathode substrate, a cathode conductive layer, a sub-emitter layer, a dielectric layer and a gate layer; wherein the gate layer is provided with a potential difference to induce The electron emission from the electron emission source layer is provided by the high voltage supplied from the anode conductive layer to provide acceleration of the electron beam, and the electron has sufficient kinetic energy to impinge the phosphor powder on the anode structure. Layer is excited to emit light. Thus, in order to move electrons in a field emission display, the need to monitor the vacuum apparatus holding at least 1〇_5 ^ Torr. " The following degree of vacuum 'allows electrons to obtain a good mean free path' while avoiding contamination and poisoning of the electron-emitting source and the phosphor powder region. In order to make the electrons have enough energy to hit the fluorescent powder, it is required between the two boards.

Powder, the so-called electron emission source layer is mainly composed of carbon nanotubes. Since 1991, it has been extremely high by Nji Ershan (Nature 354, 56 (1 991 )). Electronic characteristics, and & used after being used in a variety of electronic components, '❿n carbon nanotubes can have a ratio of more than 500, more than 500, and high rigidity, the length and width of the length of the question is more than lOOOOGPn, and nano The tip of a carbon tube or the lack of a multi-scale "...these characteristics are recognized as: an atomic electron source (electronfield emitter) material, for example; ^ the use of an electron emission source on the cathode structure of an electro-radiation display. J Wild Hair: With the physical characteristics shown above, it can also be designed to use more than carbon, such as screen printing or film processing, to be used in electronic components.

Even if it is heated and cast, the electron emission limitation of the carbon nanotubes formed between the pixel pores will greatly reduce the electronic effect. In addition, the patent application is changed to the cathode electrode of the electron emission source junction structure to achieve the mass production mechanism of the activated electron emission type coating layer, but the material to be coated is dependent on the fracture or Breaking, for a stripping mechanism, stripping to reach a uniform sentence [Summary of the invention] The main coating surface of the present invention is affixed to the application of the film forming method, the hot melt adhesive or the covering layer is easy and cost-effective. For the de-strength, in the large-size mask machine, there is still a limit to the technique of injecting the hot-melt paint. The factor of implementation is the only high-viscosity material, even if it is above 1000 Å, due to field emission. The display components are wider and smaller 'with these high-viscosity viscers: the coating process, often the part of the region is dissolved in the working space gap, I Hai and other air gaps will affect the sol more than the entanglement; the dense and, according to this will be difficult Fully activating the surface, the surface activation area of the source is not uniform, and the display has previously applied for a coating structure to form a so-called source. Although the process is limited by the process, the directly formed coating layer f is deactivated for future mass production. No. 94105204 to facilitate the application of the polymer material to remove the hot melt adhesive or to be high and low, the mechanism is still unclear, the film material is required to enter the dephosphorization process, and the material for the large size surface is deeper than the three-pole sticker. The coating molecular material is applied to the fact that it is necessary to remove the film from the film, and it is necessary to solve the above-mentioned defects. The present invention is in the process of removing the film, because of the material of the film.
