OLED Devices Have Bright Future With Technology Developed By Wako Scientists

The highly expensive and complicated manufacturing process is the main hindrance in the advancement of the OLED technology.

An advanced technology developed by a group of scientists from the Advanced Science Institute, RIKEN in Wako has succeeded in producing highly efficient OLED by eradicating the specific limit of doping concentration from the manufacturing procedure.

The Wako scientists made it possible by employing a metal dopant that prevents the self quenching metal complex interactions that reduces the phosphorescent ability of OLED.

Zhaomin Huo and his team have employed amidinates in modifying the metal complex of iridium. And the scientists have used the iridium-amidinate metal complex in model OLED display panels which use minimum driving voltages while emitting dazzling florescent green light.

The group of Wako scientists has discovered that in manufacturing the highly efficient next generation OLED devices (including better OLED televisions) the use of various doping concentrations ranging from 7% to 100% would be possible. This paves the way for the advancement of practically applicable OLED devices.
