Quantum dot light-emitting diodes (QLEDs) with advantages in color quality, stability, and cost-effectiveness are emerging as a candidate for single-material, full color light sources. Despite the recent advances in QLED technology, making high-performance flexible QLEDs still remains a big challenge due to limited choices of proper materials and device architectures as well as poor mechanical stability. Here, we show highly efficient, large-area QLED tapes emitting in red, green, and blue (RGB) colors with top-emitting design and polyimide tapes as flexible substrates. The brightness and quantum efficiency are 20 000 cd/m2 and 4.03%, respectively, the highest values reported for flexible QLEDs. Besides the excellent electroluminescence performance, these QLED films are highly flexible and mechanically robust to use as electrically driven light-emitting stickers by placing on or removing from any curved surface, facilitating versatile LED applications. Our QLED tapes present a step toward practical quantum dot based platforms for high-performance flexible displays and solid-state lighting. © 2014 American Chemical Society. © 2021 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/openAccessElectroluminescenceFlexibilityLight-Emitting DiodesPolyimide TapeQuantum DotColorCost EffectivenessElectroluminescenceFlexible DisplaysLightLight Emitting DiodesMechanical StabilityNanocrystalsOptoelectronic DevicesOrganic Light Emitting Diodes (Oled)PolyimidesSemiconductor Quantum DotsCurved SurfacesDevice ArchitecturesFlexibilityFlexible SubstrateInformation DisplayMechanically RobustQuantum-Dot Light Emitting DiodesSolid State LightingQuantum EfficiencyArticle10.1021/nn502588k2-s2.0-84906708532
