Japan is the first to launch a new generation of OLED materials in South Korea. What is the possibility of commercialization?

Japan took the lead in revealing a new generation of OLED materials in South Korea, making Korea a threat to the throne in the display field, and causing the industry to pay attention to the commercialization of this element.

Japan has invested its accumulated material technology in the development of OLEDs. According to Korean media reports, Japanese companies Idemitsu Kosan and Toray announced the third-generation thermally activated delayed fluorescent material (TADF) at the end of last month. The two companies signed an OLED cooperation agreement in September 2017, and a new one was announced after two years. Generation OLED materials.

The two companies plan to commercialize the raw material in 2022, which is more meaningful than South Korea. Currently, Samsung Samsung and LG Display are developing TADF-related technologies, but they have not yet disclosed the related finished products. Therefore, Japan is taking the lead. Aroused the attention of the Korean industry and the media.

Idemitsu Kosan is Japan's second largest oil company, and holds a number of international patents for blue OLED light-emitting materials. According to industry evaluations, OLED displays manufactured using TADF raw materials can overcome the shortcomings of poor OLED luminous efficiency and short life.

The South Korean industry takes this development very cautiously. The Korean display industry generally believes that the raw materials may enter the mass production stage and may have yield problems. It may take some time to invest in the manufacture of televisions and mobile phone panels.

Relevant persons in the industry also pointed out that TADF technology has the danger of accelerating the heating of OLED elements, and high brightness may have a problem of reducing luminous efficiency.

Another person in the industry believes that although the Korean display industry is also developing TADF, the technical difficulty is very high. From the perspective of Japanese companies' published finished products, it is still difficult to determine that TADF technology has been successful, and it is necessary to pay close attention to related developments.
