Combined Materials to Deliver Brightest Organic EL Device

摘要

Idemitsu Kosan Co., Ltd., and Toray Industries, Inc., have jointly developed an organic electroluminescent (EL) device that offers one of the highest luminous efficiencies, with a near practical range of 46cd/A. The new device employs thermally activated delayed fluorescence (TADF) and red fluorescent materials. The new technology combines Idemitsu Kosan's TADF material, which offers an exceptional luminous efficiency and lifespan, and Toray's new red fluorescent material, which features a narrower emission spectrum than its conventional counterparts, thus providing high color purity. With this combined technologies, the new development could help reduce the costs and energy consumption of organic EL displays while enabling wide color gamuts.
