beeOLED: BeeOLED Emerges from Stealth to Develop Deep-Blue OLED Emitter Tech

Dresden, Germany-based startup beeOLED has raised €13.3 million ($14.4 million) in series A funding to further develop its high-efficiency deep-blue emitter technology, and advance the emitters toward commercial availability. The company aims to overcome a bottleneck that has to date prevented a market-ready technology that delivers deep-blue OLED emitters that are both stable and efficient at the same time. Currently, according to the company, such emitters are either only stable, like fluorescent emitters, or efficient, like phosphorescent emitters and/or thermally activated delayed fluorescence emitters. The company said its intrametallic emission technology has previously demonstrated high stability and high efficiency when...
