Hyperfluorescence™ (HF), widely recognized as the fourth generation of OLED emitting technology, provides high efficiency and pure color with a narrow emission spectrum without using any rare metals such as iridium and platinum. The very narrow FWHM smaller than 25 nm across all RGB colors enables HF to cover a wide color space close to BT.2020. Kyulux has been focusing on the development of HF technology and materials since 2015. The cornerstone for Kyulux’s steady development growth is our original Materials Informatics System, Kyumatic. Kyumatic consists of quantum chemistry, machine learning, mass molecular generation, device simulations and experimental data management. It enables not only the material development expedition close to hundred folds, but also the curation of proper materials combination in the emissive layer. As the most promising cutting-edge technology, HF continuously progresses and advances ever highly efficient performance for the next-generation OLED display. Alongside the deep-blue progress, Kyulux will present its latest achievements at the conference. Top emission green HF has achieved BT.2020 color requirement with very narrow emission, FWHM <17 nm. The current efficiency and lifetime have met the industrial targets for mobile applications. Kyulux also made a breakthrough in blue HF lifetime by combining multiple approaches such as developing robust blue TADF and dopant as well as the proper combination with the adjacent materials. The company plans to achieve the industrial target by the end of this year.
