Blue for OLED screens
South Korean scientists say they have developed a new material they call "true blue" that should speed up the development of organic light-emitting displays (OLEDs), according to a weekend report. The announcement comes from a chemistry professor at Pusan National University, Jin Sung-Ho, who led the state-funded project, which was performed in conjunction with engineers at Seoul National University. Up until now, scientists had trouble developing efficient blue lights for the application. OLEDs require green, red and blue lights in their screens for proper color reproduction.
With this breakthrough, Sung-Ho says OLED screens can be made more efficient. Compared to LCD screens, OLED displays offer advantages such as a greater field of vision, better color accuracy and use up less energy, leading many to believe it will be the technology of choice in the future of displays. South Korea is home to the world's largest manufacturers of LCD screens and produces the most LCDs.
