Overview
- A peer-reviewed Nature paper details a fully stretchable OLED that achieves a record 17% external quantum efficiency for such devices.
- Transparent electrodes made from MXene combined with silver nanowires create a conductive percolation network that preserves charge injection during deformation.
- An exciplex-assisted phosphorescent emissive layer in a stretchable matrix raises exciton utilization to over 57%, supporting high light production.
- Mechanical testing shows stable luminance under large tensile strain, with the Nature summary reporting 1.6× stretch and press accounts citing up to 2.0×, along with modest losses over limited cycling.
- Early applications are expected in wearable and on-skin displays, with remaining challenges including device lifetime, truly stretchable encapsulation against oxygen and moisture, image stability, and scalable manufacturing.
