Consequently, curved displays have gained popularity as one of next-generation display technologies that combines functionality and attractivity. While planar displays remain the dominant form of displays, emerging applications, from wearable devices 1, smart skin 2, 3 to curved optics, soft robotics 4, 5, and home embellishment, require three-dimensional curved structures 6, 7, 8. This proposed technology paves a feasible solution of mass production of adaptive curved displays and sets the trend for the next-generation display. Theoretical models and finite element calculations are established to describe the tensile behavior of the structures under different boundary conditions and agree with the experimental results. A prototype stretchable display is demonstrated that it can maintain electrical performance under biaxial strain and adapt to different Gaussian curvature surfaces, including cylindrical, spherical, saddle and arbitrary surfaces. Further, the freed-up space by folded interconnects allows the structure to be compressed. The vertical interconnects are patterned on a flexible printed circuit board (FPCB) using laser cutting and folded up via specially designed molds. We connect square islands by vertical interconnects to relieve the stress concentration and provide extra deformation patterns. Inspired by kirigami and auxetic structures, we propose an approach that combines luminescent elements and rotating square tessellations to create a stretchable, arbitrary curve adaptive display. Due to the immutable pixel spacing, existing commercial curved displays are flexible but not compatible with undevelopable surfaces. Curved displays can adjust their shape to accommodate different objects and are used in electronics and decorative lighting.
