OLED organic light-emitting materials have high technical barriers and my country’s market size continues to expand

OLED, also known as organic light-emitting diode, is an emerging flat panel display technology. OLED organic materials are the main materials for the production of OLED display panels, including OLED organic light-emitting materials and OLED basic materials. Among them, OLED organic light-emitting materials are the core component of OLED display panels.

OLED organic light-emitting materials can be divided into two categories: small molecule materials and polymer materials. Since the application technology of polymer materials is not yet mature, small molecule materials are currently the mainstream materials for industrial production of OLED display panels. Small molecule materials include general layer materials and light-emitting layer materials. The general layer materials are divided into hole injection layer materials, electron injection layer materials, hole transport layer materials and electron transport layer materials; the light emitting layer materials are divided into green light host/guest materials, red light host/guest materials and blue light host/guest materials. Material.

According to “2023-2028 OLED organic light-emitting materials industry market in-depth research and investment prospect forecast analysis report” released by the Industrial Research Center > It shows that the development of OLED organic light-emitting materials has gone through two stages so far. The first-generation OLED organic light-emitting materials are traditional fluorescent materials such as tris(8-hydroxyquinoline)aluminum. Traditional fluorescent materials are limited by spin statistics and can only use singlet excitons to emit light, resulting in a waste of triplet excitons. Therefore, the first-generation OLED The energy utilization rate of organic light-emitting materials does not exceed 25%.

The second generation of OLED organic light-emitting materials is phosphorescent materials such as iridium complexes. Electrophosphorescent devices made of phosphorescent materials have greatly improved exciton utilization and luminous efficiency, and are currently the mainstream OLED organic light-emitting materials. However, precious metals such as iridium and platinum used in phosphorescent materials are expensive and resource-scarce, which greatly limits the further development of OLED organic light-emitting materials. Therefore, there is an urgent need to develop materials with high exciton utilization, high luminous efficiency, and low cost. OLED organic light-emitting materials.

In recent years, in order to promote the technological upgrading of my country’s OLED organic light-emitting material research and development and the rapid development of the industry, the Chinese government has successively promulgated the “Guidance Catalog for the First Application Demonstration of Key New Materials (2019 Edition)”, “Classification of Strategic Emerging Industries”, “Industrial and the Ministry of Information Technology’s Implementation Opinions on Promoting the Quality Improvement of Manufacturing Products and Services” and other policies. In addition, as OLED display panels are widely used in televisions, mobile phones, tablets, computers, indoor lighting, automotive light sources, biomedical equipment and other fields, the demand for OLED display panels in my country has surged, driving the rapid development of OLED organic light-emitting materials. The market scale of OLED organic light-emitting materials continues to expand.

Industry analysts said that at present, the supply of global OLED organic light-emitting materials is basically in the hands of overseas companies. Compared with developed countries abroad, my country’s OLED organic light-emitting material industry started late, and the technical barriers to OLED organic light-emitting materials are high. There is a lack of domestic companies that can produce high-quality OLED organic light-emitting materials on a large scale. In the future, with the continuous improvement of the production technology level of my country’s enterprises and the long-term support of policies, my country’s OLED organic light-emitting materials have great development potential.
