Abstract: A carbon nanotube suspension uses water as the basic solvent added with dispersant, stabilizer, coalescing aid, adhesion promoter, and a carbon nanotube. The basic solvent and the above solutes form a low viscosity solvent with carbon nanotube suspending therein. Therefore, the carbon nanotube suspension is formed to serve as a source material of the electron emission source of a field-emission display. That is, the carbon nanotube can be coated on a surface for forming the carbon nanotube electron-emission layer.

Abstract: A method sequentially performs electrophoresis depositing carbon nanotube of field emission display. Only one cathode strip is subjected to electrical field at one time during electrophoresis deposition. Therefore, the electrophoresis deposition is confined to local area. A cathode plate includes a plurality of cathode strips and the cathode strips sequentially have potential difference with respect to the anode strips, whereby only one electrical field is present for one pixel at one time and carbon nanotube is formed at that pixel. The cathode strips are sequentially applied with voltage for global electrophoresis deposition.

Abstract: A method of manufacturing carbon nanotube electron field emitters by do-matrix sequential electrophoretic deposition forms an electric field for only one pixel in the electrophoretic deposition, so that only the electrophoretic area has the electrophoretic effect. Longitudinally aligned cathode electrodes of a cathode plate include a plurality of electron field transmitters at the depositing positions, and anode electrodes of an anode plate perpendicular to the cathode electrodes are preinstalled, and a switch unit provides a potential difference for each cathode or anode electrode by a sequential change, and only one alternating pixel having an electric field between the cathode and anode plates per unit time of the electrophoresis produces a deposition effect in the area for manufacturing a carbon nanotube electron field transmitter, and the sequential voltage change of each cathode or anode electrode is used to achieve the electrophoretic deposition effect for all pixels of the cathode plate.

Abstract: A scanning-matrix type electrophoresis deposition method fabricates nanotube electron emission source. During the electrophoresis deposition process, the electrical field is applied to a single pixel to localize the electrophoresis deposition. The cathode strips on the cathode plate are vertical to the anode strips of the anode plate. A sequential pulse voltage signal is applied to the cathode strips and the anode strips. Therefore only one electrical field is present for one pixel defined by the cathode strip cross with the anode strip at one time and nanotube is formed at that pixel.

Abstract: A method activates the electron emission surface of a field emission display. After an un-activated cathode plate is manufactured, a protective layer is formed by coating a solvent to one face of the electron emission source layer. A coating is applied to the protective layer to form a covering layer on the surface of the electron emission source layer. The covering layer is cured and then a mold-releasing cylinder is used to release the dried film. The surface of the electron emission source layer can be uniformly activated. The electron emission source layer is then baked again to remove the remaining solvent.

Abstract: The mini multilayer band-pass filter for balanced to unbalanced signal transformation includes a multilayer substrate and multiple coupling transmission lines. The multiple coupling transmission lines can be formed on one layer of the multilayer substrate or respectively formed on the corresponding layers. Every two of the coupling transmission lines are coupled in order to form a band-pass filter. The first coupling transmission line is configured with an unbalanced input terminal and the last coupling transmission line is configured with two balanced output terminals. With this configuration, a conventional balanced to unbalanced transformer is not necessary to be configured between the band-pass filter and the post circuit. Hence a volume of the circuit can be reduced, and also a loss of the signal transformation can be reduced. Further, a noise of a coupling effect generated between the filter and the balanced to unbalanced transformer can be avoided.

Abstract: A method for enhancing the adhesion and life span of the electrophoresis deposited electron emission source. The method can form a siloxane film on the surface of carbon nanotubes during a one-time electrophoresis deposition process. The siloxane film is then sintered to form a silicon dioxide film on the surface of the electron emission source. This can prevent the intoxication of carbon nanotubes, thereby enhancing the life span of the carbon nanotubes and the adhesion of carbon nanotubes on the electrode layer.

In addition, the present invention enhances the density of Carbon Nano-Tube (“CNT”) and thereby improves the electron density of the electron beams.

Abstract: A method for batch fabricating electron emission source of electrophoresis deposited carbon nanotubes includes preparing a semi-manufactured cathode structure and a metallic plate connected with electrophoresis electrodes. The cathode structure and the metallic plate that are parallel to each other are separated with a fixed distance and are rinsed in an electrophoresis solution. A processe is performed to remove the bubbles formed in the cathode structure, and to electrophoresis deposit the carbon nanotubes onto the cathode structure. After each deposition process is completed, the cathode structure is baked under a low temperature so as to remove the residual solution remained on the cathode structure. After a homogeneous carbon nanotubes layer is deposited to form the electron emission source, a sintering process is performed so as to transfer the chargers into conductive metallic oxide salts. Thereby, the electron conduction of the carbon nanotubes and the cathode electrode layer is enhanced.
