A simple and universal strategy for easily controllable, reproducible and color‐stable white organic light‐emitting diodes (WOLEDs) utilizing a single‐emitting‐layer consisting of two complementary nondoped emitters with blocked energy transfer is demonstrated. The device efficiencies achieve 3.64 cd/A and 3.81 lm/W, respectively, with a small CIE fluctuation of only (0.009, 0.016) from 6.3 to 924.5 mA/cm 2 .
