Direct-contact dual emitting layers with tailored host materials improve exciton recombination and luminous efficiency in OLEDs.
NHC-based Ir(III) complexes shorten radiative lifetime and suppress quenching to deliver efficient, stable true blue OLED emission.
Specific amine compounds in the hole transport region suppress exciton diffusion, raising OLED luminous efficiency while extending service life.
A triazine-based OLED compound composition balances electron and hole transport to improve efficiency, thermal stability, and lifespan.
