Bright, low‐voltage driven colloidal quantum dot (QD)‐based white light‐emitting devices (LEDs) with practicable device performances are enabled by the direct exciton formation within quantum‐dot active layers in a hybrid device structure. Detailed device characterization reveals that white‐QLEDs can be rationalized as a parallel circuit, in which different QDs are connected through the same set of electrically common organic and inorganic charge transport layers.
