Red light auxiliary layer material (Red prime) is a kind of OLED panel emitting layer (EML) material. It refers to a functional material that can convert various forms of energy absorbed from the outside into non-equilibrium light radiation.
OLED, organic light-emitting diode, is the core of the third generation display technology and has been widely used in mobile phones, computers, smart wearable devices, televisions and other fields. OLED panels are mainly composed of cathode, anode, hole injection layer (HIL), electron injection layer (EIL), light emitting layer (EML) and other parts. Among them, the luminescent layer material is the core material of OLED panels. It accounts for about 12% of the cost of mobile phone OLED panels and about 27% of the cost of computer OLED panels. The performance of EML materials has a direct impact on the luminous efficiency of OLED display devices.
At the same time, OLED light-emitting layer materials are also the organic materials with the highest technical barriers in OLED panels. According to different light-emitting colors, they can be divided into Red (Red Host, Red Prime, Red Dopant), Blue (Blue Host, Blue Prime, Blue Dopant), Green (Green Host, Green Prime, Green Dopant) 9 categories. Among them, compared with blue light and green light auxiliary layer materials, the development and application progress of red light auxiliary layer materials is lagging behind.
According to the “2023-2028 Red Prime Auxiliary Layer Material (Red Prime) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that the technical barriers to Red Prime materials are extremely high. For a long time, the domestic market has been dominated by foreign companies that entered the OLED material market earlier, have a variety of core patents, and have relatively mature technologies, including UDC of the United States and DuPont of the United States. , Japan’s Tokuyama, Germany’s Merck, South Korea’s LG Chem and other companies.
Restricted by technology and patent barriers, Chinese companies entered the Red Prime material market late. However, in recent years, as the patents of most foreign companies have expired and local companies have increased their efforts in technological research, Chinese companies have gradually realized the success of OLED terminal materials such as Red Prime. It is localized and has more competitive advantages in terms of cost performance, delivery cycle, and after-sales service.
The company that has achieved large-scale mass production of Red Prime in China is Shaanxi Light Optoelectronic Materials. The company independently develops and produces Red Prime materials and has its own patent protection. It has now become the exclusive domestic supplier of Red Prime materials for BOE and CSOT, and is also the The only supplier of Red Prime materials for the photovoltaic flat panel series. At the same time, Wright Optoelectronics is also actively expanding its Red Prime production capacity. The company’s OLED terminal material research and development and industrialization project will be completed in 2025. After completion, it will add 4 tons of Red Prime material production capacity.
Industry analysts said that Red Prime (red light auxiliary layer material) is the core luminescent material of OLED panels First, its industry development is closely related to the development of the OLED industry. Under the background of the rapid development of the domestic OLED panel industry, the demand for Red Prime materials continues to increase. The domestic OLED panel market size will exceed 230 billion yuan in 2022. Against this background, the demand for Red Prime materials is approximately 700 million yuan, and the market development prospects broad. However, due to technical limitations, at this stage, only Wright Optoelectronics has achieved mass production of Red Prime materials in my country, and there is still huge room for development in the industry in the future.
