There are a wide variety of polarizing films (polarizing films), with the display panel and automotive fields being their largest demand ends.

Polarizing film, also known as polarizing film, is the core material of polarizers. It refers to a transparent film based on polymer materials that can produce polarized light or suppress the polarization effect of the film. Polarizing film has excellent performance and has the advantages of UV protection, effective filtering of light reflection, and high transparency. It is widely used in display panels, automobile manufacturing and other fields.

There are many types of polarizing films. According to different reflection principles, polarizing films can be divided into semi-scattering polarizing films, scattering polarizing films, reflective surface polarizing films, etc.; according to different base materials, polarizing films can be divided into dye polarizing films, iodine-based polarizing films, metal polarizing films, polyethylene polarizing films, etc. Vinyl polarizing film, etc. Reflective surface polarizing film is the mainstream product in the polarizing film market. It has the advantages of high reflectivity, low operating cost, and small light transmission loss. It is widely used in LCD monitors, cameras and other products.

Polycarbonate film, polyolefin film, polyester film and other high molecular polymer films are the main raw materials of polarizing films. Polyester film has the advantages of good heat resistance, high mechanical strength, good tensile resistance, oil resistance, chemical corrosion resistance, etc., making it an ideal raw material for polarizing films. In recent years, with the continued efforts of local companies, my country’s low-end polyester film production capacity has continued to expand. However, currently, due to factors such as high technical barriers and high production costs, my country’s high-end polyester film production capacity is low and demand is highly dependent on imports, which brings certain challenges to the development of the polarizing film industry.

According to the “2023-2028 China Polarizing Film (Polarizing Film) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that polarizing films are mainly used in display panels, automobile manufacturing and other fields. In the field of display panels, polarizing films can be used on the inside and outside of liquid crystal displays to reduce reflection problems; in the field of automobile manufacturing, polarizing films can be attached to car windows to effectively prevent ultraviolet rays and filter reflected light. Benefiting from the gradual transfer of the global display panel industry to my country and the increasing prosperity of the automobile industry, my country’s polarizing film market demand is increasingly strong.

Global polarizing film industry research first originated in the United States. American Polaroid Company (Polaroid), American Polarizers Company, and American Swift Glass Company are world-renowned manufacturers. In terms of the local market, attracted by market prospects, the number of companies in my country’s polarizing film industry continues to grow, driving competition in the market to become increasingly fierce. Weida Optoelectronics, Fosu Technology, Jiemei Technology, etc. are the main manufacturers of polarizing films in my country. Fosu Technology has independent research and development capabilities for high-performance polarizing films, and its product quality has a competitive advantage in the global market.

Industry analysts said that polarizing films have excellent performance and have broad application prospects in display panels, automobile manufacturing and other fields, benefiting from downstream industries. The pace of development is accelerating, and my country’s polarizing film market space continues to expand. Reflective surface polarizing film has the advantages of low operating cost and small light transmission loss, and is a mainstream product in the polarizing film market. It is expected that companies with high-performance polarizing film production capabilities will occupy a larger space in my country’s market in the future.
