The 51 year-old Jang jin and 37 year-old Park Gyu-chang Professorial research team of the department of Information Display, Kyunghee University, yesterday announced that it has succeeded in developing 'Phosphorescent organic light-emitting diode (OLED)' that measures 2cm in width, 1.5cm in height and 3mm in thickness. All the OLED materials developed so far consist of fluorescent materials that emit light only when electric flows and stop emitting promptly if electricity is turned off. However, the research team applied a fluorescent material that emits light for a long time even after electricity is turned off for the first time. "The new phosphorescent OLED is brighter than OLEDs made from fluorescent materials, resulting in sharply reduced power consumption and extended life-span," Professor Park said. " In addition, it can have the effect of two conventional display outputs by allowing screens on both sides (front and back)," The technology was developed as a result of a three-year R&D grant sponsored by UDC, who retains the source technology of phosphorescent materials, and is scheduled to be unveiled at the Information Display Association International Symposium planned to be held in the U.S on 24 this year.
