Cynora has announced they have made significant progress in its highly efficient blue material developments during the last six months which the company believes will enable the company to develop materials that reach the performance levels required by the OLED industry.
According to Cynora they have been working on organic TADF emitting materials during the last five years, and since 2015, Cynora has applies its experience and know-how to develop pure organic highly efficient blue dopants for vacuum deposition.
The Cynora TADF technology combines high efficiency (which the company claims is three times better than the state-of-the-art fluorescence technology) together with long lifetime.
Further, OLED displays incorporating these blue TADF materials are expected to reduce power consumption up to a factor of 2.
Cynora announced they have developed deep blue material reaching an EQE of 16.3% (at 100 cd/m2) compared to 3% reached in October 2015, a factor 5 improvement in six months.
In parallel, the company is using sky blue material to improve the device lifetime. A significant increase in the lifetime to more than 400 h (LT50, 500 cd/m2) has recently been achieved from a level of a few minutes in last October.
Thomas Baumann, CSO Cynora, said, "We have yet to reach the performances requested by the OLED display industry." Thomas added, "but our rapid progress during the last 6 months proves our capability to reach the performance levels we have defined together with our key customers to support their technical roadmap. We will use the coming months to combine both efficiency and lifetime in a single deep blue material."
Cynora said that they own a broad IP portfolio on TADF with over 100 patent families and is aiming for over 600 patents.
