Description:
SAIT's unique technologies for developing highly efficient and robust green Pt and Ir complexes for next-generation OLED displays are presented. Our approach focuses on two key innovation points: maximizing efficiency and device lifetime by enhancing horizontal emitting dipole orientations and emission spectral shapes, and improving molecular stability through the development of new emitting chromophores. We also address the challenge of long turn-on times by reducing the permanent dipole moments of the complexes, thereby improving display quality at low luminance levels. The resulting OLED devices exhibit excellent performance, with higher efficiencies and longer lifetimes compared to devices using conventional dopants. These developments hold great promise for the future of OLED technology, enabling the creation of even more advanced and high-performing displays.
