Description of the invention (1) The present invention is a method for manufacturing a fluorescent screen of a cathode ray tube and its structure, especially a color laser isolation using a fine carbon powder and other coarse powder particles to form a fluorescent screen. 5 ο The structure of the known cathode ray tube curtain is shown in Figure 1. It has-broken glass (1) 'inner surface and the difference between the coating thickness is less than 1 um, and the diameter of the micro-carbon powder between 〇2 ~ 〇4um is blackened. The substrate (2) to isolate the fluorescent areas (4) arranged between the blackened substrates (2), and each fluorescent area (4) has a plurality of aligned fluorescent spots (3) in order to conduct red, Three or more colored lights such as blue and green, and a metal film (5), such as an aluminum film, covering the fluorescent area (4) and the blackened substrate (2) is extended above and above, so that the electron beam excited by the cathode (6) Have a good substrate when entering the fluorescent area (4), to avoid the dissipation of reflection. The micro-carbon powder constituting the above-mentioned blackened substrate (2) cannot actually pile up a sufficient thickness on the glass (υ) to isolate the fluorescent area (4). The reason is that when the fluorescent screen is flooded, it will cause carbon The surface of the powder is chipped or hardened and peeled off, so that the electron beam excited by the 5 n cathode passes through the metal film (5) and reaches the fluorescent area (4) before forming an adjacent fluorescent area (4) due to poor isolation. The different colors of the laser electron beams between different colors cross the mixed light, causing the loss of color and the change in the projection brightness, which reduces the luminous quality of the screen. Economy The purpose of solving the above problems is as follows: 1. To provide a method and a structure for manufacturing a cathode ray tube screen that does not generate color interference and projection interference of adjacent fluorescent regions. 1. To provide a method that can completely isolate adjacent fluorescent light. The method of manufacturing the isolation zone of the district. 2. Provide a substance for stacking the isolation zone. _____ -2- This paper size photo paper Laijia County (CNS) A4il # (2I〇x297y ^)-5 ο 5 11 Economic Central Bureau Employee Consumption Cooperation Du Yinzhuang V. Invention Description (2 A7 B7 It is tied on the glass for forming the screen, and it is coated with high enough polyvinyl alcohol (PVA) in a stepwise manner, and each polyvinyl alcohol and the two sides form a higher micro-carbon powder and powder. The granular mixture isolation area is decomposed by nitric acid (HNO3) and the polyvinyl alcohol disposed by the gap is washed away with water; the mixture of phosphor and polyvinyl alcohol is coated on the area of the eliminated polyvinyl alcohol, and removed by exposure The polyvinyl alcohol in the mixture leaves the majority of the fluorescent dots formed by the phosphor. Wash the unexposed area with water and apply a flat paint over the fluorescent area to make it flush with the top edge of the isolation area. The metal film is coated to make a good substrate for a cathode ray tube, and the area covered by the substrate is baked at a high temperature to form a well-isolated fluorescent screen. Further explanation of this case is performed in conjunction with FIGS. 2 to 9. Brief description of the figure) Figure 1 is a side cross-sectional view of a known fluorescent screen structure. Figure 2 to Figure 8 are side cross-sectional views of the steps of the method for manufacturing a cathode ray tube in the present case. Polyethanol for most arrays / Tellurium 3 is coated between each polyvinyl alcohol to form an isolation zone. Figure 4 is the elimination of polyvinyl alcohol of each array. Figure 5 is the mixture of phosphor and polyvinyl alcohol in the area where polyvinyl alcohol is removed. Figure 6 The masking process is implemented so that the phosphor and polyvinyl alcohol installation area only leaves the fluorescent dots and fluorescent areas composed of most phosphors.
