An extremely high‐efficiency solution‐processed white organic light‐emitting diode (WOLED) is successfully developed by simultaneously using an ideal dendritic host material and a novel efficient orange phosphorescent iridium complex. The optimized device exhibits forward‐viewing efficiencies of 70.6 cd A −1 , 26.0%, and 47.6 lm W −1 at a luminance of 100 cd m −2 , respectively, promising the low‐cost solution‐processed WOLEDs a bright future as the next generation of illumination sources.
