We have demonstrated a novel white OLED with two vertically stacked emission units. The first emission unit employs a blue fluorescent emitter and the second one uses green and red phosphorescent emitters. The device architecture achieves low‐driving voltage and the combination of the emitters without deterioration in luminous efficiency.
