P‐10.2: The Fabrication and Characterization of Stretchable Metal Wires

Abstract

In recent years, flexible display becomes a research hotspot for its applications in foldable or rollable devices. However, these flexible displays are still unable to stretch or twist, which limit their future applications. In this research, we demonstrated a stretchable circuit capable of 20% elongation by using patterned aluminum (Al) as conductor and Poly‐dimethylsiloxane (PDMS) as substrate. On the basis of simulation, the Al conductor was fabricated on the neutral layer to minimize the tensile stress. After bonding the light emitting diode (LED) chips onto the circuit, a stretchable passive matrix micro‐LED (SPMLED) display was prepared to accommodate up to 10 % deformation.
