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.”

The 4th Generation Emitting Material, Hyperfluorescence

Thermally activated delayed fluorescence(TADF), still under development to complement OLED emitting materials insufficient as both fluorescence and phosphorescent materials, takes time to be commercialized at the present stage. Even Kyulux considered the most advanced company in terms of TADF technology hasn’t yet to commercialized TADF dopant suitable for display.

Adachi, CTO of Kyulux said the unprepared TADF host material is an obstacle to the commercialization of TADF, so the full width at half maximum of emitting peak is too wide to be applied to display. To solve this problem, the 4th generation hyperfluorescence is under development to commercialize the TADF material.

<Kyulux CTO Adachi>

Hyperfluorescence aims at having the effect of a phosphorescent material by adding TADF dopant to existing fluorescence host and dopant.

<Hyperfluorescence Effect>

This effect has a structure that can solve both the full width at half maximum of TADF and the low brightness of fluorescence materials as seen in the above figure, Adachi emphasized.

<Hyperfluorescence vs General fluorescence>

As seen in the above photo, Kyulux’s OLED made of general green fluorescence material and OLED made of hyperfluorescence by adding TADF to this material have a distinct difference on the same substrate.

Kyulux’s goal is to commercialize hyper fluorescence by 2017. Its target is PMOLED.

OLEDON with Dankook University succeeding in developing next-generation ultra high resolution patterning deposition technology

/in , , , , , , , , , /by

Chin Byung-Doo, professor at Dankook University and Hwang Chang-Hoon, professor at Dankook University and CEO of OLEDON announced that they have succeeded in developing evaporation pattern deposition technology which can realize 0.38um shadow distance (SD) at SID 2017.

Mr. Hwang, CEO of OLEDON announced at 2016 IMID Business forum that he succeeded in implementing plane source evaporation and 1.1um shadow distance with 100um-thick shadow mask. At that time, Mr. Hwang said, ‘If we reduce the step height to 3μm, theoretically, we can implement the shadow distance down to 0.38 um, so the OLED panel resolution will be possibly more than 2250ppi.’

At the SID 2017, OLEDON’s solid result of implementing SD 0.38um in application of actual plane source drew great attention from people in relevant industries regarding the possibility of mass production.

Current OLED panel production technology has the limits on implementing the resolution higher than QHD (about 600ppi) for about 3 um thick shadow which causes overlapping micro patterns in the UHD (over 800ppi) AMOLED patterning process to degrade the fine pattern density. Consequently, OLED panels are produced only at QHD level.

If OLEDON’s surface source patterning deposition technology is applied to mass production, the shadow distance can be reduced to 0.38 ~ 0.56um, which can improve the resolution about 8 times higher. In addition, if scale-up development is applied to a large size OLED display production in the future, it is possible to manufacture a micro AMOLED device equipped with super ultra resolution (SUHD) resolution higher than 3300ppi.

<Shadow data from the surface source deposition technology>

Hwang Chang-hoon, CEO of OLEDON said, ‘using the idea of primarily evaporating the organic material and its deposition on the metal surface in the vacuum environment to form organic molecular film and re-evaporate it for the second coating deposition, we have found a condition to minimize the evaporation angle of the organic molecular beam. ”

<The principle of film source presented by Mr. Hwan at the SID>

With the recent focus on display resolution, OLEDON’s research results are expected to bring significant impact on the relevant industry.

Meanwhile, Prof. Hwang Chang-hoon has been developing new deposition technology for 25 years via a deposition specialist company. He holds the original patent of surface source deposition technology (Linear organic device mass production equipment with top-down thermal induction deposition: Registration No. 101206162000).
