In this work, we demonstrate a light‐emitting diode with voltage‐controlled multicolor electroluminescence. The emission color can be finely tuned by the applied voltage, corresponding to a color change from red to orange, yellow and finally to green. Voltage‐controlled red‐green multicolor electroluminescence can take place in either the CsPbBr 3 or CdSe QDs, depending on the ratio of the recombination zone between these two materials.
