CYNORA has made progress in its highly efficient blue material developments during the last six months, a strong indicator for reaching performance levels requested by the OLED industry.

CYNORA has been working on organic TADF (thermally activated delayed fluorescence) emitting materials during the last five years. Since 2015, CYNORA applies its experience to develop pure organic highly efficient blue dopants for vacuum deposition.

The TADF technology combines high efficiency (three times better than the state-of-the-art fluorescence technology) together with long lifetime. OLED displays incorporating blue TADF materials will reduce power consumption up to a factor of two.

CYNORA has developed deep blue material reaching an EQE of 16.3% (at 100 cd/m2) compared to 3% reached in October 2015, a factor five 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.

“We have yet to reach the performances requested by the OLED display industry” said Thomas Baumann, CYNORA’s CSO, “but our rapid progress during the last six 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 owns a broad IP portfolio on TADF with more than 100 patent families and is aiming for more than 600 patents.
