Low Driving Voltage, High Quantum Efficiency, High Power Efficiency, and Little Efficiency Roll-Off in Red, Green, and Deep-Blue Phosphorescent Organic Light-Emitting Diodes Using a High-Triplet-Energy Hole Transport Material
Improved device performance in red, green, and deep-blue phosphorescent organic light-emitting diodes is achieved using a new high-triplet-energy hole transport material. The driving voltage is lowered and the power efficiency is improved by more than 70% using the new hole transport material.
