Abstract
The authors have demonstrated the structure optimization for high-efficiency white organic light-emitting diodes (WOLEDs) using codoped blue emitting layers with different functional materials or hybrid-spacer between emitting layers. The optimized WOLEDs characteristics showed the maximum external quantum efficiency of 11.8%, the maximum luminous efficiency of 25.29 cd/A, and Commission Internationale de I´Eclairage coordinates of (x = 0.37, y = 0.38), respectively.
