Abstract
- In this work, we fabricated a biaxially stretchable light-emitting diode (LED) display based on a wavy structured-metal electrode grid packaged together with LED chips. The micro-electromechanical systems (MEMS) fabrication process was utilized to fabricate the wavy-structured metal connections and rigid islands. The resulting LED display can be readily bent, rolled, stretched and even washed with no degradation of its image quality. Here at least 1000 stretching cycles at a 10% strain can be tolerated. This work demonstrated the potential of inorganic materials as stretchable displays and MEMS compatible processes which can be used as stretchable electronics fabrication processes.
