South Korea successfully developed blue OLED dopants
Korean industry has successfully developed new technology to develop blue OLED dopants (Dopant) materials, the future panel industry will have more choices, no longer need to rely on the Japanese industry's exclusive supply.
According to ZDNet Korea, Creative Material has developed a patented blue OLED dopant that can replace Japan's Idemitsu Kosan, the first to be supported by a large enterprise without the support of a large enterprise. Technology into the commercialization of the Korean material industry.
In 1995, after the development of blue OLED dopants, to the current total in Japan to apply for more than 30 pieces of technical patents, of which eight patents valid until 2034, and exclusive anthracene (Anthracene) structure of blue materials and Pyrene (Pyrene) blue dopant combination of OLED material technology.
So the panel to buy blue dyed products to the industry must be even with the blue material to buy, Samsung Display, LG Display and other major Korean technology are all so.
The Blue Dye developed by Material Science completely out of the technology patent, the molecular design to abandon the use of electronic receptors (Electron Acceptor), and the electronic body (Electron Donor) into the molecule, to improve the OLED material luminescence Efficiency and extended luminous life, while reducing the solvent discoloration (Solvatochromism) phenomenon, showing a real blue.
Material Science said that the use of new materials structure and synthesis technology, the development of differentiated blue OLED dopants, the panel industry to provide more material selectivity; recently also developed to extend the blue fluorescent life of the thermal activation of delayed fluorescence (Thermal Activated Delayed Fluorescence; TADF) technology.
