Abstract

Abstract : 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.
