The application range of ITO conductive films continues to expand, and local companies have a competitive advantage in the global market
ITO conductive film refers to a film material obtained by sputtering a transparent indium tin oxide (ITO) conductive film coating on a transparent organic film material using magnetron sputtering and other methods, and then subjecting it to high-temperature annealing treatment. ITO conductive films have the advantages of good chemical stability, good conductivity, low resistivity, good wear resistance, high temperature resistance, corrosion resistance, etc., and are widely used in optical equipment, solar cells, household appliances, gas sensors and other fields.
Preparation methods for ITO conductive films include magnetron sputtering, reactive ion plating, pyrolysis spraying, chemical vapor deposition, etc. Magnetron sputtering is the mainstream preparation method for ITO conductive films. This method has the advantages of green environmental protection, high production efficiency, uniform film formation, high deposition rate, and convenient operation. It can be subdivided into DC magnetron sputtering and radio frequency magnetron. There are two types of sputtering methods. In recent years, the maturity of my country’s magnetron sputtering technology has continued to improve, which provides favorable conditions for the development of the ITO conductive film industry.
According to the “2023-2028 China ITO Conductive Film Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, ITO conductive films are widely used in optical equipment, solar cells, household appliances, gas sensors and other fields. In the field of solar cells, ITO conductive films have excellent conductivity and light transmittance and can be used to produce heterojunction solar cells; in the field of household appliances, ITO conductive films can be used to produce liquid crystal displays for refrigerators, washing machines, air conditioners and other appliances; In the field of gas sensors, ITO conductive films can be used as sensor electrode plates to ensure their normal operation.
In recent years, with in-depth research and technological progress, the application scope of ITO conductive films in my country has been further expanded, and flexible electronic products have become its emerging application field. Flexible electronic products include smart wearable devices, flexible displays, flexible smart keyboards, flexible electronic smart desk lamps, etc. Flexible ITO conductive films usually use ITO conductive films as raw materials, combine them with elastic polymers, and then undergo deep processing to obtain finished products. This film has the advantages of folding, curling, and high conductivity, and is an important component of flexible electronic products.
The world’s largest ITO conductive film manufacturer is Japan’s Nitto Denko Co., Ltd., with a market share of nearly 40%. The main manufacturers of ITO conductive films in my country include Rijiu Optoelectronics, CSG Group, Kaisheng Technology, etc. Rijiu Optoelectronics is a representative enterprise of ITO conductive films in my country, occupying nearly 30% of the global market share, and its product quality has reached the world’s advanced level.
Industry analysts said that ITO conductive film, as a conductive material, is widely used in many fields. In recent years, the application scope of ITO conductive films has continued to expand, and the industry’s development prospects continue to improve. Compared with Japan, my country’s ITO conductive film industry started late, but its development momentum is rapid. As my country’s leading enterprise, Rijiu Optoelectronics ranks second in the world in market share. In the future, as local companies continue to exert their efforts, my country’s ITO conductive film industry will gradually develop in a high-quality direction.
