At the 4th OLED KOREA CONFERENCE, Kyulux and CYNORA, the leaders in the development of next generation emitting materials, announced the results of research and future development directions.

Junji Adachi, CEO of Kyulux, said, “We are developing Hyperfluorescence in the form of adding a TADF dopant to the existing fluorescent host and dopant.” He also emphasized that the emission FWHM (full width at half maximum) of Hyperfluorescence is about 35% of that of TADF, and the luminance is about twice as high, and this material can solve the drawbacks of TADF (wide FWHM and low luminance) at the same time.

The latest Hyperfluorescence, which Jundi Arachi introduced, has efficiencies of red 28 cd /A, yellow 43 cd/A, green 81 cd / A, and life span is 10,000 hours, 62,000 hours, and 48,000 hours based on LT50 (1000nit) respectively. The color coordinates are red (0.64, 0.36), yellow (0.46, 0.52), and green (0.28, 0.65).

Andreas Haldi, CYNORA’s Chief Marketing Officer of CYNORA, said that the blue TADF emitter developed by CYNORA now has a color coordinate of 0.16, EQE of 24% and 10-hour lifetime (LT97 @ 700nit).

The performance is more than twice as efficient as the blue material currently used in OLEDs, and the color coordinates (0.10) are similar but the lifespan is short. He added that the Blue TADF emitter is scheduled to be developed within 2018 and will be available for mass production in 2019.

He also mentioned that the manufacturing cost is reduced and the power consumption is reduced, thereby minimizing battery consumption if blue TADF emitters with high efficiency are used instead of conventional low-efficiency blue materials. At the same time, it is expected to be able to improve the resolution of OLEDs and be applied to large-scale vacuum processing lines of major panel makers.
According to CYNORA, next step is to develop green TADF emitters (2019) and red emitters (2020) after finishing the development of blue TADF emitters (2018). Thus, it might be completed ‘RGB TADF emitter development’ by 2020.

Cynora, TADF will contribute to high-resolution implementation of OLED devices and panel cost reduction

/in /by

At the Global Materials Tech Fair 2017 held on September 22 in COEX, CEO Ko Chang-hoon of EM Index, Cynora’s Korean partner, announced the development of the thermally activated delayed fluorescence, blue TADF, which is currently under development at Cynora.

<CEO Ko Chang-hoon of EM Index>

Generally, the blue light emitting material is insufficient in life and efficiency compared to red and green. For this reason, OLED panels for mobile devices are manufactured relatively large in blue pixel size compared to other pixels, in the OLED panel for TV, blue light emitting layers are laminated twice. The blue TADF is the material that is being developed to overcome the limitations of this blue light emitting material.

CEO Ko Chang-hoon mentioned “Applying blue TADF increases lifetime and efficiency, so it does not need to increase pixel size and it is advantageous for high resolution implementation” and emphasized “In mobile devices, it will be advantageous to reduce power consumption as well as realize high resolution and in case of TV, it will be advantageous to reduce the panel cost because only one layer of blue light emitting layer needs to be formed.”

He referred to the recent investments of € 25 million from Samsung Venture Investment and LG Display and explained that it was a proof that blue TADF is attracting a lot of attention.

It is also close to the efficiency, lifetime and color purity of the blue TADF required by major OLED panel makers and is expected to meet these requirements by the end of 2017.

CYNORA presents record results for high-efficiency blue OLED emitters

/in /by

CYNORA, 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 commercialization 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 2017, CYNORA presented a blue emitter with a performance that was very close to the requirements of the panel makers. Using TADF technology, the company has achieved 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’s latest patent-protected materials show a performance in the range of the customer´s specifications for blue” said Thomas Baumann, CYNORA´s CSO, “This is the best overall performance of a high-efficiency blue emitter so far from what CYNORA has seen. In the finalization of CYNORA’s product development, CYNORA will now focus on moving the emission peak slightly towards 460 nm.”

 

“CYNORA’s progress in the last few months makes us very confident that CYNORA can commercialize CYNORA’s first highly efficient blue emitter by the end of this year, as planned” said Andreas Haldi, CMO at CYNORA. “But CYNORA’s goal is to become a leading OLED material supplier by providing emitters of all display colors. Therefore, CYNORA is planning to follow up on the blue emitter with a green emitter by 2018 and a red emitter by 2019.”

CYNORA, what is its research and development goal from now on?

/in /by

During the 3rd OLED KOREA CONFERENCE, Andreas Haldi of CYNORA presented the research result and future development direction with the topic on Efficient blue TADF emitter: material in high demand.

Andreas Haldi said that he did an in-depth anaylsis on the spectrum characteristic development of deep-blue TADF emitter classification and the interaction between host and guest. He revealed that the EQE (1000nits) of the deep-blue TADF emitter improved from 15% to 24% and life time (500nits) rose to 1000h from 300h.

However, it was mentioned that the efficiency and life time showed a decrease due to material quenching when applying the deep-blue TADF emitter to the OLED. He added that in order to resolve this problem, CYNORA is doing a joint development with a panel company and plans to reach a minimum of 0.2 for CIEy, above 15% for EQE(1000nits), more than 100h for LT97(700nits) by 2017, which is the aim for mass producing a mobile and TV deep-blue TADF emitter.

Andreas Haldi revealed and expected that in the case of using the improved deep-blue TADF emitter, the production unit price and power consumption decreases and at the same time makes it possible to produce an improved OLED display resolution which can be used in large vacuum processing lines of main panel production companies.

He also presented that with the device based light-blue TADF emitter a host and stack which can apply material refining technology and injection, layer, transport layer, and blocing layer was developed.
He ended with that in regard to the future direction of the blue-emitter development it will improve the EL peak to its fullest and set a goal and develop a deep-blue TADF emiiter that has 60nm FWHM and 460nm wavelength range.

As the leading company that has actively done studies on TADF material for many years, CYNORA is focusing on blue emitter material which is the biggest issue of improving the performance of OLED displays.

An update of the status of TADF emitters at CYNORA will be shown by the CMO, Dr. Andreas Haldi during the Session “Better Materials for Better Performance”. Andreas Haldi will present improved OLED devices with a sky-blue material with an EQE of 24% and with 1000 h lifetime (LT80), both measured at display brightness. The performance of these devices is so far the best result combining efficiency and lifetime that has been reported for the TADF technology with blue emission. Andreas Haldi will also disclose in his presentation some more details relating to the planned commercialization of CYNORA’s blue TADF emitters by end of this year.

<Picture : CYNORA>

UBI Research has recently announced that the OLED emitting material market is increasing sharply and is expected to reach about US$ 980 million in 2017. With Apple starting to use OLED displays in the near future, the demand for high-performance OLED panels will increase significantly. Therefore, the panel makers are currently pushing the adaptation of high-efficiency blue pixels in their panels to gain an edge towards the competition.

CYNORA Achieves a New Milestone in Efficiency and Stability of Blue TADF Emitters for OLEDs

/in , , , , , /by

CYNORA, a leader in TADF (thermally activated delayed fluorescence) materials, has developed new material classes that combine both, high efficiency and long lifetime, for blue emission. With these new achievements, the company is on track to reach the performance requested by the OLED industry. The commercialization of CYNORA´s TADF materials is therefore still planned for the end of 2017.

Earlier this year, in May 2016, CYNORA had established two blue emitter systems where one of them showed a high efficiency while the other showed a long lifetime. During the last 6 months CYNORA has made further, significant progress by combining high efficiency and long lifetime in a single blue emitter system. In an OLED device, the new blue material reaches 14% EQE (external quantum efficiency) together with a lifetime of 420h (LT80, at 500 cd/m2, λ < 480 nm). With this performance, CYNORA has now shown that blue TADF emitters can reach OLED display specifications soon.

“Our constant progress on blue TADF emitters was made possible by our growing team of TADF experts and by the close collaboration with CYNORA’s customers” says Thomas Baumann, CSO at CYNORA, “We have developed several classes of high performance TADF materials which we are currently optimizing for market readiness at the end of next year.”

CYNORA’s dopants are fully organic and designed for existing vacuum deposition. The company will adapt the blue TADF emitters for solution processing in a second step. With its blue TADF technology CYNORA will enable device makers to provide OLED displays with significantly increased energy efficiency and higher display resolution.
