Novel Host-Guest System for Drastic Improvement in the Lifetime of a Deep-Red OLED that Satisfies the Red Chromaticity of the BT.2020 Standard

摘要

We developed a novel host-guest system that increases the lifetime of a deep-red phosphorescent OLED covering the wide color gamut of the BT.2020 standard. An OLED that employs this host-guest system has a ～5.4 times longer lifetime than an OLED that employs the conventional system.
