Visualization is a cornerstone in human–computer interaction, evolving from large screens to mobile devices and now to wearable display technology. However, conventional batteries and displays lack the softness and stretchability inherent to human skin. Here, a fully flexible, all-in-one electronic display skin by integrating a flexible microLED display, a stretchable circuit, and a Zn|PAM|V₂O₅ hydrogel battery pack is developed. Vapor-phase bulk transfer is used to efficiently and accurately transfer 10 000 microLEDs onto a flexible substrate, ensuring high flexibility and ultra-thin (240 µm). The flexible hydrogel battery pack provides sustainable energy, with a high specific capacity of 331.3 mAh g⁻¹. Additionally, a transparent stretchable circuit board (maximum stretch 40%) is made by 3D printing technology. The skin display exhibited exceptional stretchability and biocompatibility, conforming to movements while maintaining high-resolution dynamic visual outputs. These innovations pave the way for advanced skin-implanted displays, promising transformative applications in information interaction, healthcare, and artificial intelligence.
