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

DRESDEN, Germany, Sept. 1, 2023 — 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 employed in other display technologies. So far, however, it has not been useable in OLEDs.

Now, said the beeOLED team, it has managed to make molecules used in its technology compatible with the vacuum processing technology used in high-volume OLED display manufacturing. The current advancement allows for 100% internal quantum efficiency, which, company CTO Carsten Rothe said, is a prerequisite for the highest power efficiency in OLED displays.

Innovation Industries Inc. and eCapital Corp. co-led the funding. According to Innovation Industries director Tom van Vuren, increasing the efficiency of blue emitters for OLED displays is considered a driver to reduced energy consumption in modern devices.
