45‐5: Green Phosphor Sensitized Multiple Resonance OLEDs with Current Efficiency of More Than 250 cd/A

Abstract

An advanced organic light‐emitting diode (OLED) architecture featuring a green phosphorescent emitter with multiple resonance sensitization achieves a notable current efficiency exceeding 250 cd/A at a density of 10 mA/cm2. This design integrates phosphor‐sensitized fluorescent technology, resulting in significant longevity enhancement, superior color accuracy and reduced sensitivity to doping concentrations.
