20‐2: <i>Invited Paper:</i> Maximizing Blue OLED Power Efficiency Using Ultra‐Strong p‐Dopants

Blue phosphorescent emitters significantly boost current efficiency in organic light‐emitting diode (OLED) displays but require host materials with high triplet energy and large bandgaps. Consequently, conventional hole‐transport layers create large hole‐injection barriers. We show that combining deep‐HOMO hole‐transport materials with our recently developed ultra‐strong p‐dopants effectively reduces these barriers, paving the way for blue OLEDs with maximum power efficiency and enhanced lifetime.

Abstract

Blue phosphorescent emitters significantly boost current efficiency in organic light‐emitting diode (OLED) displays but require host materials with high triplet energy and large bandgaps. Consequently, conventional hole‐transport layers create large hole‐injection barriers. We show that combining deep‐HOMO hole‐transport materials with our recently developed ultra‐strong p‐dopants effectively reduces these barriers, paving the way for blue OLEDs with maximum power efficiency and enhanced lifetime.
