Description of the Invention (1) Background of the Invention: The present invention relates to an anti-reflection / anti-static coating that can form a pure black display panel on an information display, especially one An antistatic coating solution uniformly mixed with carbon black and blue additives is uniformly coated on the surface of an information display display panel to form an antistatic coating layer, and the blue additives are used to effectively compensate The carbon black's excessive absorption of blue light in the spectral wavelength range of 400 ~ 700nm enables the antistatic coating solution to form a pure black display panel on the information display. Previous skills: According to the current application of anti-reflection (Anti-Reflection) and anti-static (Anti-Static) coatings in the production of cathode ray tubes, generally spraying, spin coating ( spin coating) or ion coating (Sputtering coating), the chain containing tin oxide (Antimony-doped Tin Oxide, hereinafter referred to as ATTO 'for example: chain-tin dioxide Sb-Sn02) or indium tin oxide (Indium_doped Tin Oxide , Hereinafter referred to as ITO, such as: tin-indium trioxide In203-Sii02) antistatic coating solution, coated on the outside surface of the display panel with a curved surface on the cathode ray tube to form an antistatic coating layer,嗣 Apply an anti-reflection coating solution containing SiO2 (such as sand gel) to the anti-static coating layer to form an anti-reflection coating layer to realize Antistatic and anti-reflective effect. However, in recent years, in order to improve the viewing angle and appearance of the cathode ray tube, manufacturers and manufacturers of the cathode ray tube have gradually designed curved display panels to be flat rectangular. Due to this design change, It is loved by consumers and has become popular in the market. It has almost replaced the curved cathode ray tube. In the flat right-angle cathode ray tube widely used today, as shown in Fig. 1, the glass in the center position on the display panel is thinner than the glass in the peripheral position, resulting in the penetration rate of the glass in the center position. 80%, and the penetration rate of the surrounding glass is only about 72%, so in order to make these-2-X 297 mmi (Please read the precautions on the back before filling this page)-522426 A7 B7 Ministry of Economic Affairs Printed by the Intellectual Property Bureau's Consumer Cooperative Co., Ltd. 5. Description of the invention) The overall display panel of the flat right-angle cathode ray tube has a more uniform transmission rate, which is generally reduced by reducing the transmission rate of the entire display panel (about reducing the center position to about 50%), in order to reduce the gap ratio of the glass transmittance between the central and peripheral positions on the display panel, so that the display panel can present a more uniform overall picture. Taking the coating method currently used on the flat tube of the flat right-angle cathode ray tube in the industry as an example, in addition to using ion sputtering, a material containing ITO, titanium metal (Ti) and titanium nitride (TiN) components is coated. To the display panel, most of them are anti-static coating solutions containing conductive materials such as silver-palladium (Ag-Pd) or silver-gold (Ag-Au) components, which are spin-coated by a spin coating method. Spraying is applied to the display panel to reduce the transmittance of the entire display panel, thereby reducing the ratio of the transmittance of the glass between the central and peripheral positions. However, whether the former or the latter method is used, the production cost is quite expensive. In view of this, the inventors have proposed to add carbon black to the antistatic coating solution. The carbon black can be effectively adjusted by adjusting the amount of carbon black through a simple and low-cost coating process. On the surface of a display panel of an information display, the conductive properties of an antistatic coating layer formed and the uniformity of the transmittance of the entire display panel. However, due to the carbon black added in the coating process, among colored lights with a spectral wavelength in the range of 400 to 700 mn, the light absorption of blue light is much greater than other colored lights. This feature will make carbon black added. After the component's antistatic coating solution is applied to the surface of the display panel, the antistatic coating layer formed by it will show a yellow and black background color, which will destroy the appearance color of the display panel and the image color of the information display. Pure and not acceptable to consumers. Summary of the Invention: In view of the foregoing, the addition of carbon black with superconductivity to the antistatic coating solution will cause the problem of yellowish black background color of the display panel. The inventor has invented a method that can form a pure color on the information display. The anti-reflection and anti-static coating of the black panel is mainly composed of carbon black powder and blue additives with a spectral wavelength of 400 ~ 500nm, mixed in a certain ratio, and then a certain proportion of dispersant is added to make the two uniformly mixed and adjusted. 1-4 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ------- Γ 丨. ^ -------- Order -------- -Line · (Please read the precautions on the back before filling this page) 522426 A7 B7 V.
