Abstract Realizing of full-color quantum-dot LED display remains a challenge because the poor stability blue and immature inkjet-printing color patterning technology. Here, we develop multifunctional tandem by stacking yellow with organic using an indium–zinc oxide intermediate connecting electrode. Under parallel connection alternate-current driving, is full-color-tunable, which can emit red, green primary colors as well arbitrary that cover 63% National Television System Committee triangle. series direct current efficient white light high brightness 107000 cd m −2 maximum external quantum efficiency up to 26.02%. The demonstrated hybrid LED, multi-functionality full-color-tunability light-emission, could find potential applications in both full-color-display solid-state-lighting.
