Focusing on the development of quantum dot-based flexible and stretchable displays, our research group is dedicated to pioneering advancements in next-generation display technologies. We proposed high-efficiency full-color QLED arrays using high-resolution intaglio transfer printing (^(ⅰ)Nature Communications, 2015). We also developed an ultrathin skin-attachable QLED display (^(ⅱ)Advanced Materials, 2017) that can visualize various information acquired from wearable electronics. Furthermore, we demonstrated highly bright and transparent QD-LEDs (^(ⅲ)Advanced Materials, 2017) with an ultrathin form factor and high color purity. Based on ultrathin QLEDs, we reported 3D foldable QLEDs (^(ⅳ)Nature Electronics, 2021), utilizing controlled folding techniques to create customized 3D architectures. We also developed intrinsically stretchable QLEDs (^(M)Nature Electronics, 2024; ^(ⅴ)Nature Nanotechnology, 2026) featuring high power density, high patterning resolution, and excellent color purity. Recent developments in stretchable QD color converters have further expanded the potential of stretchable display technologies (^(ⅵ)Advanced Materials, 2025).
