Two 3‐stack tandem white OLEDs devices with blue‐yellow‐blue and blue‐blue‐yellow structures with fluorescent blue and yellow phosphorescent materials were investigated about various performances for display applications. We report CIE coordinates of (0.335, 0.313) and 23.6 % EQE (external quantum efficiency) at 1000 cd/m 2 in blue‐blue‐yellow structure.
