(iTers News) -CYNORA, a leader in TADF, thermally activated delayed fluorescence materials, has made major breakthroughs in its highly efficient blue material developments, a result of its 6 month-long research and development effort. The technology breakthrough has a far-reaching implication for the OLED industry’s future rise as mainstream replacement for LCD panel, as the industry is now grappling to enlarge OLED lifetime and improve its performances.

For the past 5 years, CYNORA has been working on organic TADF emitting materials during the last 5 years.

Since 2015, CYNORA has applied its experience to develop pure organic highly efficient blue dopants for vacuum deposition.

The TADF technology boasts of a high efficiency, 3 times better than the state-of-the-art fluorescence technology, while long lifetime.

OLED displays incorporating blue TADF materials will reduce power consumption up to a factor of 2.

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 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.

“We have yet to reach the performances requested by the OLED display industry” says Thomas Baumann, CYNORA’s CSO, “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.”
