Putting Organic EL on Display
Thin, transparent, and flexible – a trio of properties that make organic EL displays the next phase in the evolution of TVs, smart phones, and other digital devices. It was Idemitsu Kosan who first developed practical applications for blue organic EL, and in 2018 we received the prestigious Imperial Invention Prize for this transformative breakthrough. Since those early successes, we’ve greatly improved the functionality of this extraordinary technology. Our goal is to reinvigorate the display industry, while highlighting Japan’s world-leading technological capabilities.
A Colorful Man
“Ever since I was little, I loved things that give off light,” says Tetsuya Masuda, leader of the organic EL material development and technical sales team. “I always wondered how TVs could display so many colors.” His lifelong curiosity serves him well as he handles a myriad of responsibilities, from developing testing protocols to interacting directly with customers. It's a colorful job for a colorful individual.
Learning from Failure
Organic EL displays utilize ten or more types of organic materials, and Tetsuya looks for the ideal combinations. Based on current knowledge and previous test results, he develops a hypothesis and tests it again and again. “Tests are successful less than one percent of the time,” he admits. Fortunately, a great deal can be learned from these failures. Tetsuya further augments his knowledge by consulting the world’s most advanced case studies, poring over countless research papers and patent documents in English.
A Shining Success
In May 2018, the man who loves things that give off light gave off a little light of his own. After submitting a research paper summarizing his team’s results, Tetsuya received a prestigious award from The Society for Information Display, the world’s largest academic society in the field of display technologies. “The ideas we presented in the paper might be all around us in a few years,” he predicts. Clearly, it’s his time to shine.
The Global Stage
“Working on the global stage means representing Japan,” Tetsuya affirms. It is a responsibility he takes on with enthusiasm. “I want to energize the Japanese display industry with organic EL technology developed by Idemitsu.” And then, as if to emphasize this point, he waves good-bye and gets back to work.
