Cynora, established in 2003 in Germany, was a developer of materials for OLEDs and OPVs. Cynora started out to develop copper-based OLED compounds, in addition to developing flexible OLED and OPV technologies.
The company later changed direction and focused on TADF OLED emitters, specifically aiming to develop an efficient blue emitter. The company hoped to have a commercial blue by 2017, but it was not successful.
In 2020 Cynora announced its first commercial product, a fluorescent blue emitter that is 15% more efficient that current fluorescent blue emitters on the market. Cynora branded its new material as cyBlueBooster. We are not aware of any companies that actually adopted this new material. In March 2020 we posted an interview with Cynora's CEO to discuss this new material.
In 2021, Cynora announced that it achieved a breakthrough in its deep-green TADF material, which it brands as cyUltimateGreen. Cynora started to offer test kits of the new deep-green emitter and Cynora promised it will follow soon with a deep-blue TADF solution. The company did not provide any updates since.
In June 2022 it was reported that Samsung Display acquired Cynora for $300 million.
The latest Cynora OLED news:
An interview with Cynora's CMO Dr. Andreas Haldi - talking about TADF, lifetime, color points and more
German TADF developer Cynora presented its latest blue TADF material in May 2018 - with a CIEy of 0.14, EQE of 20% and a lifetime of 20 hours LT97 at 700 nits. Cynora expects to have blue material in the mass production by 2020.
Cynora's Chief Marketing Offer, Dr. Andreas Haldi was kind enough to answer a few questions we had regarding TADF emitters, the differences between next-generation emitter technologies, lifetime, color points and more.

CYNORA, a leader in TADF (thermally activated delayed fluorescence) materials for OLEDs, presents its newest high-performing blue emitting materials at the SID Display Week 2018 in Los Angeles. The company is currently working with the key display makers to finish the commercialization of the industry’s first blue high-efficiency emitter.
OLED displays have become standard for premium mobile and TV displays in the last couple of years. However, those OLED displays have not yet reached their fullest potential. High-efficiency blue OLED emitters are needed to reduce power consumption and increase the display resolution further. Despite urgent requests by the OLED display panel makers for a high-efficiency blue emitter in the last few years, no material supplier has yet been able to produce such an emitter.
German TADF developer Cynora recently participated in the international OLED summit in China, and the company presented its latest blue TADF material that features a CIEy of 0.18, EQE of 21% and a lifetime of 10 hours LT97 at 700 nits. This is an improvement of the material shown in September 2017 (which had the same specification but with a lower EQE of 14%).
Cynora reports that during the last 24 months, the company achieved its most important goals - high efficiency and a satisfying color point. It has made "tremendous progress" in the last year on the lifetime front and is now close to commercial lifetime specification.
Many OLED producers believe that Ink-Jet printing of OLED emissive materials is the best way to achieve lower-cost OLED TV production, and to enable OLEDs to compete in the medium part of the TV market. Ink-Jet printing is an efficient process (less material waste compared to evaporation) and it can be very quick as well. The main drawbacks of inkjet are the limited resolution and the need for soluble emissive materials which are less efficient compared to evaporation ones.

These challenges are being overcome, and it seems that at least four groups (in Korea, Japan and China) are charging forward towards mass production of ink-jet printed OLEDs. Ink-jet printer makers and soluble material suppliers are also optimistic ink-jet printing commercialization will soon be here as the material performance gap is diminishing.
In 2015 the EU launched a 3-year €4 million OLED lighting project, the LEO project (Low-cost / energy Efficient OLEDs) that had an aim to develop efficient and cost-effective bendable OLED lighting technologies. The project consortium included Osram, and Cynora.
A month before the project officially ends, the partners updated on their progress. For this project, the partners develops several technologies, including low-cost metal foils integrating OLED anodes and possibly backside monitoring printed circuits, smart OLED top-electrode architectures and light out-coupling solutions and a novel thin film top-encapsulation strategies. These technologies together increased the light output by 50% while providing better surface scratch resistance.
A few days ago, Cynora hosted the 2017 International TADF Symposium in Frankfurt, Germany. Cynora reports that about 150 attendees from all over the world listened to experts from the industry and academia and were updated on the latest news regarding TADF OLED emitters.
Cynora itself showed an update on its latest blue emitter. The company now has material that features a CIEy of 0.18 (target - 0.1), EQE of 14% (target 15%) and a lifetime of 10 hours LT97 at 700 nits (target is over 100 hours). Cynora says that development is progressing well and it is confident it will reach its target material performance by the end of the year.
Cynora announced that it finalized its Series-B funding round. Both Samsung (via Samsung Ventures) and LG Display participated in this round which totaled €25 million. Both LGD and samsung will also establish separate joint development efforts to assist in advancing Cynora's R&D.
Cynora did not disclose how much did each company invest, although earlier reports suggested that LG invested €15 million while Samsung invested €10 million.
A report from the Korea Herald suggests that Samsung Display decided to invest €10 million in TADF developer Cynora, which follows LG Display's €15 million investment in the company. Both companies aim to secure access to next-generation emitter technology.
The Korean report actually states €100 million from SDC and €150 million from LGD - but this is surely a mistake as it's highly unlikely that Cynora could be raising such a huge sum of money at this stage. An earlier report from ETNews claimed LGD's investment totaled $9 million.
In May 2017 Cynora announced a new blue TADF emitters that achieves a 15% EQE at 1000 nits with an emission peak of 470 nm and a LT97 of > 90 hours (at 700 nits) on a device level. Cynora has stated several times that it aims to commercialize its first highly efficient blue TADF emitter by the end of this year.
According to Cynora, the performance requested from customers is an EQE (at 1000) of over 15%, a lifetime (LT97 at 700 nits) of over 100 hours and a wavelength of 460 nm (color purity FWHM 60 nm).
ETNews reports that Cynora is finalizing its latest financing round, with aims to raise €15 million. LG Display will participate in the round, investing $9 million, and Samsung Display is also considering a similar sized investment.
Cynora, based in Germany, is developing OLED emitters, and has recently announced its blue TADF OLED performance. Cynora's new blue achieves a 15% EQE at 1000 cd/m² with an emission peak at < 470 nm and a LT97 of > 90 hours (at 700 cd/m²) on a device level. Cynora says that it is very confident that it can commercialize its first highly efficient blue emitter by the end of this year, as planned.
