Efficient and mechanically robust stretchable organic light-emitting devices by a laser-programmable buckling process

Abstract

Highly stretchable organic light-emitting diodes tend to suffer from a lack of mechanical robustness. Here, Yin et al. fabricate ordered buckled films by laying flexible light-emitting diodes on laser-ablated, prestretched substrates. The devices exhibit good emission stability over 15,000 stretching cycles.
