Abstract

Recent advances in skin-attachable electronics have attracted substantial interest because of their potential in various fi elds

such as robotics, healthcare, and wearable technology. Among various electroluminescent (EL) devices, quantum dot lightemitting

diodes (QLEDs) are promising for next-generation displays due to their superior color purity, high brightness,

excellent effi ciency, high stability, and ultrathin form factors, making them promising for fl exible electronic applications.

This review outlines the recent progresses in QLEDs for skin-attachable electronics. First, materials selection and various

structural designs that impart mechanical fl exibility into QLEDs are discussed. We also discussed the design strategies of

fl exible displays based on the array of QLEDs. Then, we summarize skin-attachable displays based on the fl exible QLEDs,

including the integration with sensors capable of detecting various signals. The discussion includes the promising role of

skin-attachable QLEDs in healthcare, particularly their potential as wearable light sources for monitoring biologic signals.

Overall, this review article highlights the remarkable progress made in the skin-attachable QLEDs.
