Description of the invention (1) Background of the invention: The present invention relates to an antistatic / anti-reflective coating for an information display, especially an indium tin oxide (Indium) -doped Tin Oxide (hereinafter referred to as ITO) is added to the antistatic coating solution, carbon black is added, and the amount of carbon black is adjusted to form the surface on the display panel of the information display. The conductive properties of the antistatic coating layer and the transmittance of the entire display panel. Previous technology ... Press, the intensity of the reflected light on the surface of the cathode ray tube (CRT) of a general video display is about 4% to 8% of the incident light. Such reflected light is extremely likely to cause eyes for long-term users. Fatigue and injury, and will reduce the resolution and color contrast that should be on video displays. In addition, in high-resolution and high-quality displays that are becoming popular today, the driving voltage is generally up to 25KV, which is extremely easy to display. The formation of a static voltage on the surface causes fine dust particles in the atmosphere to adsorb on its surface, which disrupts the display quality of the display, and when the display is used in a low-humidity area, it is easy for users to receive an electric shock. Therefore, in order to solve the above problems and make the video display meet the relevant quality requirements, anti-glare, anti-reflection and anti-static (Anti-Glare) -Static) and other surface treatments, by applying multiple layers of antistatic and anti-reflection coatings, to effectively reduce the adverse effects of light source reflection on the video image and greatly reduce the static voltage accumulated on it. In recent years, due to the increasing demand of consumers for the image quality of monitors, video display manufacturers are always aiming to design and manufacture higher-quality and higher-quality displays. Because of this, the antistatic and anti-reflective effects of video displays The good and bad will become one of the important standards for evaluating the quality. Because at present, in the manufacture of cathode ray tubes, the coating treatments such as Anti-Reflection and Anti-Static are used by spray, spin coating or In the ion-sputtering method, an antimony-doped tin oxide (hereinafter referred to as ATTO, such as a chain-tin oxide Sb-Sn02) or an indium-doped oxide (Indium-doped paper size) Applicable Chinese National Standard (CNS) A4 Specification (210 X 297 male f) (Please read the precautions on the back before filling this page)

Tin Oxide，以下簡稱ITO，如：錫-三氧化二銦In203-Sn 02)成份之抗靜電塗佈 溶液，塗佈在陰極射線管上呈曲面之顯示面板之外側表面，以形成一抗靜電塗佈 層，嗣再於該抗靜電塗佈層上，塗佈一含二氧化矽(Si〇2)(如：矽質凝膠，silica gel)成份之抗反射塗佈溶液，形成一抗反射塗佈層，以實現抗靜電及抗反射之 效果。然而，近年來，陰極射線管之設計及製造業者，爲改善陰極射線管之可視 角度及外觀造型，已逐漸將呈曲面狀之顯示面板，設計成平面直角狀，由於此一 設計上之改變，頗受消費者喜愛，且已在坊間造成流行，幾乎有取代曲面狀陰極 射線管之趨勢。 按，在現今廣泛被使用之平面直角陰極射線管中，參閱第1圖所示，其顯 示面板上位於中央位置之玻璃，均較其周邊位置之玻璃爲薄，導致其中央位置玻 璃之穿透率爲80%，而周邊位置玻璃之穿透率則僅爲約72%，故爲使該等平面 直角陰極射線管之整體顯示面板具有較均勻之穿透率，一般均係藉降地整個顯示 面板之穿透率（大約將中心位置降至約50。/。），以縮小顯示面板上中央與周邊位 置間玻璃穿透率之差距比，令顯示面板能呈現更均勻之整體畫面。以目前業界在 平面直角陰極射線管平面管上所使用之塗佈方式爲例，除了利用離子濺鍍方式， 將含ITO、鈦金屬(Ti)及氮化鈦(ΉΝ)成份之材料，塗佈至該顯示面板上外，大都 係利用含銀鈀(Ag-Pd)或銀金(Ag-Au)成份等導電材料之抗靜電塗佈溶液，透過 旋轉式塗佈(Spin coating)法，將其噴塗在於該顯示面板上，以降地整個顯示面板 之穿透率’進而縮小中央與周邊位置間玻璃穿透率之差距比，然而，無論係利用 前者或後者之作法，其製作成本均相當昂貴。 發明綱要= 有鑑於前述傳統視訊顯示器上所使用之抗靜電及抗反射塗佈材料之高成本 問題，發明人乃硏究發明出一種「可令資訊顯示器具備抗靜電、抗反射且可調穿 -3 本紙張尺度適用中國國家標準（〇\：S)A4規格（2Ι〇χ 297公t ) (請先閱讀背面之注意事項再填寫本頁)Tin Oxide, hereinafter referred to as ITO, such as: tin-indium trioxide In203-Sn 02) 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 A cloth layer, and then apply an anti-reflection coating solution containing silicon dioxide (Si02) (such as a silica gel) on the antistatic coating layer to form an anti-reflection coating Fabric layer to achieve anti-static and anti-reflective effects. 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. According to the flat right-angle cathode ray tube which is widely used today, as shown in Fig. 1, the glass in the central position on the display panel is thinner than the glass in the peripheral position, which leads to the penetration of the glass in the central position. The rate is 80%, and the transmittance of the surrounding glass is only about 72%. Therefore, in order to make the overall display panel of these flat right-angle cathode ray tubes have a more uniform transmittance, the entire display is generally borrowed. The transmittance of the panel (reduced the center position to approximately 50%) to reduce the gap between the central and peripheral positions of the glass panel on the display panel, so that the display panel can present a more uniform overall picture. Taking the coating method currently used in the flat right-angle cathode ray tube plane of the industry as an example, in addition to using ion sputtering, a material containing ITO, titanium (Ti) and titanium nitride (ΉN) 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 gap ratio of the glass transmittance between the central and peripheral positions. However, whether the former or the latter method is used, the production cost is quite expensive. Summary of the Invention = In view of the high cost of the antistatic and antireflective coating materials used in the aforementioned traditional video displays, the inventors have invented a "can make information displays with antistatic, antireflective and adjustable wear- 3 This paper size applies the Chinese national standard (〇 \: S) A4 specification (2Ι〇χ 297 metric t) (Please read the precautions on the back before filling this page)

The coating layer 44 includes an inner anti-static coating layer 46 and an outer anti-reflection coating layer 48. A conductive element 50 is connected to the surface of the anti-static coating layer 46. The panel 40 is connected to a ground terminal to effectively remove the electrostatic charge accumulated on the outer wall surface of the display panel 40. The anti-reflection coating layer 48 is used to reduce the reflection of the outer wall surface of the display panel 40 to the external ambient light. The panel 14 can present a clearer video image. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The present invention is mainly a method of adding carbon black powder to a powder containing ITO conductive material, wherein the weight percentage of the added carbon black and ITO conductive powder depends on actual needs It can be in the range of about 10% to 50%. After mixing the two coating materials, a certain proportion of a surface activation agent can be added to the two coating materials, so that the two are evenly mixed to prepare a concentrated drug solution. Then, A certain proportion of the solvent is added to the concentrated chemical solution and diluted so that the carbon black and the ITO conductive powder can be uniformly mixed in an antistatic coating solution formed. In the present invention, the chemical liquid solvent may be an organic solvent containing an Off structure such as methyl, ethyl, propyl, or butanol, or a solvent such as water, ether, or ketone. The carbon black and IT0 are made conductive by these solvents The powder can be uniformly mixed to prepare a desired antistatic coating solution. The dispersant (surface activation agent) can be an anionic polymer dispersant, such as: polycarboxylate and polystyrene sulfonate, etc., and the added amount is equal to the carbon in the concentrated chemical solution.
