CYNORA presents record results for high-efficiency blue OLED emitters
CYNORA, which is based in Bruchsal, Germany, a leader in TADF (thermally activated delayed fluorescence) materials for OLEDs, has reached new performance records with its newest blue emitter material. With the current performance, the company is getting close to commercialisation of its first product by the end of 2017.
Despite urgent requests by the OLED display panel makers for a high-efficiency blue emitter material in the last few years, no material supplier has yet been able to produce such a material. High-efficiency blue emitters are needed to reduce power consumption and increase the display resolution further. At SID Display Week 2017, CYNORA will now present a blue emitter with a performance that is very close to the requirements of the panel makers. Using TADF technology, the company has achieved 15% EQE at 1000cd/m² with an emission peak at < 470nm and a LT97 of > 90 hours (at 700cd/m²) on a device level.
“Our latest patent-protected materials show a performance in the range of the customer´s specifications for blue” says Thomas Baumann, CYNORA´s CSO, “This is the best overall performance of a high-efficiency blue emitter so far from what we have seen. In the finalisation of our product development, we will now focus on moving the emission peak slightly towards 460nm.”
“Our progress in the last few months makes us very confident that we can commercialise our first highly efficient blue emitter by the end of this year, as planned” says Andreas Haldi, CMO at CYNORA. “But our goal is to become a leading OLED material supplier by providing emitters of all display colours. Therefore, we are planning to follow up on the blue emitter with a green emitter by 2018 and a red emitter by 2019.”
