Session: OLED Common Layer Materials

Maximizing Blue OLED Power Efficiency Using Ultra-Strong p-Dopants

Invited

Description:

Blue phosphorescent emitters significantly boost current efficiency in 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.
