A Biaxially Stretchable and Washable LED Display Enabled by a Wavy-Structured Metal Grid

In this work, we fabricated a biaxially stretchable light-emitting diode (LED) display based on 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. resulting can be readily bent, rolled, stretched even washed no degradation of its image quality. Here at least 1000 stretching cycles 10% strain tolerated. This work demonstrated potential inorganic materials as displays MEMS compatible processes which used electronics processes. [2022-0029]
