Abstract

The mobile display market is strongly shifting towards AMOLED technology which enables curved and flexible displays. Therefore, the demand for highly efficient OLED emitters to reduce power consumption and increase display resolution at the same time is growing. There are efficient green and red OLED emitters in mass production already, but there is no efficient blue counterpart. CYNORA´s approach to provide efficient blue OLED emitters is based on thermally activated delayed fluorescence technology. TADF emitter systems allow for an efficiency increase of up to four times compared to conventional fluorescent systems by utilizing both triplet and singlet excitons for the emission of light. At the same time, they maintain deep blue emission, i.e. CIEy < 0.2. Herein, we review our recent progress on TADF emitters, reaching 20% EQE at 1000 nits in deep blue OLED devices (< 460 nm peak wavelength) together with reasonable LT97 values. The performance of these new blue TADF emitters is now in the range of commercial requirements for blue emitters in OLED displays.
