The market size of light control film (LCF) continues to grow, with strong demand in the automotive and electronic products fields.

Light control film (LCF), also known as light collimating film and dimming film, refers to an optical film that can adjust the directionality of transmitted light. Light control film has the advantages of reducing ultraviolet radiation, reducing glare, adjustable light, and good safety. It is widely used in automobile manufacturing, electronic products, construction engineering, aerospace, medical and health and other fields.

The preparation methods of light control films include flat coating method, ion-assisted deposition method and coating method. The flat plate coating method, also known as the spin coating method, refers to mixing organic solvents and photosensitive materials to make light control materials, and then using spin coating to coat them on the surface of the substrate to obtain the finished product; the ion-assisted deposition method is the light control material. An emerging film preparation method, this method has the advantages of green environmental protection, fast deposition speed, good controllability, low operating cost, and good finished product quality. It is expected to become the mainstream preparation method of light control film in the future.

​ ​​Light control films have a wide range of applications and the industry has good development prospects. The automotive manufacturing and electronic product fields are their largest demand ends. In the field of automobile manufacturing, light control films can be used to produce vehicle display screens and automotive glass, which have functions such as screen protection, anti-blue light, anti-ultraviolet, anti-glare, and anti-reflective functions; in the field of electronic products, light control films can be used to manufacture mobile phones. , tablet computers and other electronic products privacy film. In the future, as research continues to deepen, the application scope of light control films will be further expanded.

According to the “2023-2028 China Light Control Film (LCF) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》shows that in recent years, with the growth in sales of automobiles and electronic products, the prosperity of the light control film industry has continued to increase. The global light control film market will reach 2.76 billion yuan in 2022, a year-on-year growth of 8.3%. The Asia-Pacific region is the world’s largest consumer market for light control films, accounting for nearly 50%. It is expected that in the future, with the growth of downstream demand, the market space of light control film will further expand, and its market size will exceed 4 billion yuan by 2028.

​​ ​ Major global manufacturers of light control films include Taiwan Chiefway Co., Ltd. (Chiefway), 3M Company of the United States, Avery Dennison Company of the United States, KIMOTO Co., Ltd. of Japan, Dainippon Printing Co., Ltd. (DNP), etc. In the local market, as the industry’s prosperity increases, the number of light control film manufacturers in my country continues to grow. Dingtai High-Tech and Wanshun New Materials are representative companies in my country. Dingtai Hi-Tech has independent production capabilities for two types of light-control film products: mobile phone privacy film and vehicle-mounted light-control film. Its vehicle-mounted light-control film has entered the client testing and verification stage.

Industry analysts said that as a high-performance optical film, light control film has a wide range of uses and the development trend of the industry continues to improve. In recent years, Chinese companies have continued to increase their investment in research and development of light control films, driving the expansion of their application scope. It is expected that in the future, driven by market demand, the development speed of the light control film industry will further accelerate.
