SEL develops a new Host-Guest system that enables red phosphorescent emitters with 5.4X the lifetime

Researchers from Japan's Semiconductor Energy Laboratory (SEL) developed a novel Host-Guest system that drastically improves the lifetime of OLED emitters. The researchers report that using this system, a deep-red phosphorescent emitter achieved 5.4 times longer the lifetime compared to the same emitter with a conventional system.

The researchers will present the new system at SID DisplayWeek 2018 in May. The new system is not only highly durable, it also satisfies the red chromaticity of the BT.2020 standard.
