Organic light-emitting materials are key materials for OLED panels, and the industry has broad room for development

Organic luminescent materials refer to organic materials that place organic molecules in an excited state under light excitation. The excited state organic molecules can generate photons during the process of releasing energy and returning to the ground state. According to different molecular structures, organic luminescent materials can be divided into organic complex luminescent materials, organic small molecule luminescent materials and organic polymer luminescent materials.

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​… In large-size OLED panels, organic light-emitting materials account for nearly 40% of their production costs. Benefiting from the increasingly strong market demand for electronic products, the development speed of my country’s OLED panel industry continues to accelerate. In 2021, my country’s OLED panel market size will reach 55.12 billion yuan, a year-on-year increase of 19.7%. According to the “2022-2027 Organic Light-emitting Materials Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center, With the rapid development of downstream industries, the scale of my country’s organic light-emitting materials market continues to expand, reaching 4.23 billion yuan in 2021.

There are many types of organic light-emitting materials, including fluorescent materials and phosphorescent materials. Fluorescent materials belong to the first generation of organic luminescent materials, usually made of rare earth oxides or metal sulfides as raw materials; phosphorescent materials belong to the second generation of organic luminescent materials, mainly including blue phosphorescent materials, red phosphorescent materials, and green phosphorescent materials.

At present, the world’s leading organic light-emitting material companies are mainly concentrated in Europe, the United States and Asia-Pacific countries, including the American Dow Chemical Company, the American General Display Company UDC, the German Merck Group, the Japanese Toray Co., Ltd., and the Japanese Idemitsu Kosan Co., Ltd. , South Korea’s LG Chemical Co., Ltd. and South Korea’s Samsung Group Samsung SDI, etc. The U.S. General Display Company has occupied a monopoly position in the global green phosphorescent materials and red phosphorescent materials markets, while the blue phosphorescent materials market is dominated by Germany’s Merck Group and Japan’s Idemitsu Kosan.

In recent years, my country’s local companies have further increased their research and development efforts on organic light-emitting materials, resulting in an increase in the localization rate of products. Xi’an Ruilian New Materials Co., Ltd., Jilin Aolaide Optoelectronic Materials Co., Ltd., CECEP Wanrun Co., Ltd., Beijing Dingcai Technology Co., Ltd., Beijing Xinyihua Technology Co., Ltd. are the main manufacturers of electroluminescent materials in my country. . However, due to the late start of my country’s organic light-emitting materials industry, there is a certain gap in production technology compared with overseas developed countries, resulting in high-end products being highly dependent on imports.

Industry analysts said that organic light-emitting materials are key materials for OLED panels. As the prosperity of the electronic product industry continues to increase, the OLED panel market The strong demand will bring broad development space for my country’s organic light-emitting materials industry. Currently, due to technical barriers, my country’s high-end organic light-emitting materials market is monopolized by overseas brands. However, driven by the technological innovation of local companies, the localization process of my country’s high-end organic light-emitting materials will be further accelerated.
