Abstract
Stretchable displays represent a cutting‐edge technology for creating novel freeform deformable displays. In this study, we developed a highly stretchable liquid metal‐based stretchable backplane technology for deformable micro‐LED displays. We developed a fine liquid metal patterning process and highly stretchable backplane fabrication technology to implement micro‐LED stretchable displays utilizing liquid metal electrodes. The developed stretchable display demonstrated exceptional flexibility allowing it to transition from planar to hemispherical shapes with up to 50% stretchability without disconnection of lines. Even when subjected to dome‐shaped deformation under 50% strain, the developed stretchable display utilizing liquid metal electrodes exhibited stable electrical characteristics, showcasing its practical applicability.
