Description of the Invention) Background of the Invention: The present invention relates to an antistatic / anti-reflective coating for an information display, especially an ion display method for an information display. On the outer wall of the display panel, a 1T0 transparent film and a silicon dioxide film are sequentially formed by sputtering, as an antistatic and an anti-reflection coating layer on the display panel of the information display. Previous technology: Press, the reflected light intensity on the surface of the cathode ray tube (CRT) of general video display is about 4% ~ 8% of the incident light. Such reflected light is likely to cause eye fatigue for long-time users. And damage ', 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 very easy to form on the display surface. The static voltage causes the dust particles in the atmosphere to be adsorbed on the surface, which deteriorates the display quality of the display, and when the display is used in a low-humidity area, the user is also prone to 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_Static) will be performed on the outer wall surface of the display panel of the cathode ray tube. ) 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 thereon. In recent years, due to the increasing demand of consumers for the image quality of monitors, video display manufacturers are always aiming at designing and manufacturing higher-quality and higher-quality displays. Because of this, the anti-static and anti-reflection of video displays The good and bad effect is one of the important standards for evaluating quality. Due to the current anti-glare, anti-reflection and anti-static coating processes used in the manufacture of cathode ray tubes, they are all sprayed or rotated. Spin coating methods, these coating methods are generally known as "wet coating methods", these wet coating methods must be carefully considered in the research and development and practical application of coating materials The dispersibility of the coating materials used and the added solvents. Generally speaking, traditional coating materials mainly include Yi Ning-2- This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 public love) (Please read the precautions on the back before filling this page) n ϋ »ϋ ϋ &一; a a ϋ ϋ · ϋ H ϋ ϋ I» 522421 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (2) Gel materials (such as silica gel, silica gel ), Its coating method uses a coating device to pre-configure antistatic and anti-reflection coating materials, and sprays or spins the coating method by means of a nozzle provided on the coating device. The material is uniformly sprayed on the outer wall of an information display panel in the form of mist particles, so as to form an antistatic and anti-reflective coating layer, or multiple layers of antistatic and anti- Reflective coating. In this so-called "wet coating" method, the anti-reflection and anti-static effects are not stable and cannot be effective because the spray amount and uniformity of each anti-static and anti-reflective coating material are difficult to control. Improving the video quality of video displays, and in these "wet coating" processes, each of the antistatic and anti-reflective coating materials will also cause problems such as recycling difficulties and environmental pollution. SUMMARY OF THE INVENTION In view of the many problems caused by the anti-static and anti-reflective coating materials in the wet coating process of the aforementioned traditional video display, the inventor has invented an "information display using ion sputtering method" "Coating with low resistance and low reflectance" is planned to form an ITO transparent film and a silicon dioxide film by sequential sputtering on the outer wall of an information display, respectively, by ion sputtering. An antistatic and an anti-reflection coating layer on the display panel of the display. The main purpose of the present invention is to use a dry coating method to sequentially form an ITO transparent film and a silicon dioxide film on the outer wall of the display panel of an information display. Through a simple and pollution-free process, the ITO film is used. The low-resistance characteristic and the low-reflectivity characteristic of the silicon dioxide film form an antistatic and an anti-reflective coating layer on the outer wall surface of the display panel of the information display in order.
