Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a field emission device, and more particularly to a field emission pixel tube. [Prior Art] [0002] Carbon Nanotube (CNT) is a new type of carbon material's discovered by the researcher Iijima in 1991, see "Helical Microtubules of Graphitic Carbon" S· Iijima, Nature, V〇l.354, p56 (1991). The carbon nanotubes have a very large aspect ratio (the length of which is above the order of micrometers, the diameter of 1 is only a few nanometers or tens of nanometers), has good electrical and thermal conductivity, and has good mechanical properties. Strength and good chemical stability, these properties make the carbon nanotubes an excellent field emission material. Therefore, the application of the Nile carbon tube in the field emission device has become a research hotspot in the field of nanotechnology. _] "The long carbon nanotubes are linear carbon nanotube materials prepared from super-aligned carbon nanotube arrays. First, the nanocapsule carbon nanotube film is extracted from the super-sequential carbon nanotube array." The method of returning money to (4) into a fiber or a job is screwed into a rope. This linear carbon nanotube material has a macroscopic scale and is extremely convenient for some operations. The end face mask of this nano carbon tube has a good field emission capability and is a good source of field emission electrons. It is an important application field for the field emission electron source of the pixel field of the nanometer emission field. The previous field emission pixel tube comprises a hollow casing, the body has a light exiting portion, and the inner wall of the light exiting portion is sequentially coated with a camping powder layer and an anode layer. The interior of the casing is opposite to the light exiting portion. - Cathode emission 09614561 ^ early number Α )) 1 () 1 帛 4 pages / Du 97 hundred 1013010859 - 0 1362676 I ιοί年 οι月 i 〇 body, the cathode emitter includes a carbon nanotube long line as a field emission electron source .

[0005] 然而，先前的具有奈米碳管陰極發射體的像素管，因為要將螢光粉層塗覆在殼體内一表面上，受製備工藝限制，幾何尺寸較大，一般發光區域為厘米量級，或更大，這使得基於奈米碳管的場發射像素管的應用受到了極大的限制，例如，先前的像素管無法用來組裝具有較高清晰度的大型戶外顯示器。先前的具有奈米碳管陰極發射體的像素管’由於製造過程中陰極與陽極需要準確對準，製造工藝難度大，良品率低。另外，先前的像素管製備方法’先將螢光粉層塗覆在殼體内壁上，再在螢光粉層上沈積一層有機物，然後在有機物層上鍍一陽極層，最後將有機物蒸發掉，製造工藝較複雜。 [〇〇〇6]有黎於此’提供一種尺寸小，.更易於製造的場發射像素管實為必要。【發明内容】 [0007] 一種場發射像素管，其包括一殼體及置於殼體内的一個陰'極至·夕二個陽極和設置於該陽極表面的螢光粉層，所述陰極與每個陽極間隔設置，其中，所述陰極進一步包括至少三個陰極發射體，該至少三個陰極發射體與所述至少三個陽極-----對應設置，所述每個陰極發射體包括一電子發射端，該至少三個陰極發射體的電子發射端分別罪近與之對應的陽極表面設置。 09614561^單編號AQ1Q1 第5頁/共27頁 1013010859-0 1362676 __ 101年01月10日梭正替换頁 [0008] 相較於先前技術，所述的場發射像素管的陰極發射體為奈米碳管長線，陽極為金屬杆，且每個陽極端面設置有一種顏色的螢光粉層，該場發射像素管具有以下優點：第一，通過控制設置有不種顏色的螢光粉層的陽極電壓，使所述不同顏色的螢光粉層分別發出不同強度的單色光從而搭配成不同顏色的混色光，從而實現該場發射像素管的彩色顯示；第二，這種場發射像素管的體積小，發光面積可達到毫米量級甚至更小，因此，可用來組裝[0005] However, the previous pixel tube having a carbon nanotube cathode emitter has a large geometrical size because the phosphor powder layer is coated on a surface of the casing, which is generally limited in size. On the order of centimeters, or larger, the use of nanotube-based field emission pixel tubes is greatly limited, for example, previous pixel tubes cannot be used to assemble large outdoor displays with higher definition. The previous pixel tube with a carbon nanotube cathode emitter requires precise alignment of the cathode and anode during the manufacturing process, and the manufacturing process is difficult and the yield is low. In addition, the previous method for preparing a pixel tube first coats the phosphor layer on the inner wall of the casing, deposits an organic substance on the phosphor layer, and then deposits an anode layer on the organic layer, and finally evaporates the organic matter. The manufacturing process is more complicated. [〇〇〇6] There is a need to provide a field emission pixel tube that is small in size and easier to manufacture. SUMMARY OF THE INVENTION [0007] A field emission pixel tube includes a housing and a cathode disposed in the housing, and a phosphor layer disposed on the surface of the anode, the cathode Arranged from each anode, wherein the cathode further comprises at least three cathode emitters, the at least three cathode emitters being disposed corresponding to the at least three anodes, each cathode emitter An electron emitting end is disposed, and the electron emitting ends of the at least three cathode emitters are respectively disposed adjacent to the corresponding anode surface. 09614561^单单AQ1Q1 Page 5 of 27 Page 1013010859-0 1362676 __ 101 January 101 Shuttle replacement page [0008] Compared to the prior art, the cathode emitter of the field emission pixel tube is nano The carbon tube has a long line, the anode is a metal rod, and each anode end surface is provided with a phosphor powder layer of one color.
