Stretchable light-emitting diodes (LEDs) and electroluminescent capacitors have been reported to potentially bring new opportunities to wearable electronics; however, these devices lack in efficiency and/or stretchability. Here, a stretchable organometal-halide-perovskite quantum-dot LED with both high efficiency and mechanical compliancy is demonstrated. The hybrid device employs an ultrathin (<3 mu m) LED structure conformed on a surface-wrinkled elastomer substrate. Its luminescent efficiency is up to 9.2 cd A(-1), which is 70% higher than a control diode fabricated on the rigid indium tin oxide/glass substrate. Mechanical deformations up to 50% tensile strain do not induce significant loss of the electroluminescent property. The device can survive 1000 stretch-release cycles of 20% tensile strain with small fluctuations in electroluminescent performance.
