3D curved shape display with non‐zero Gaussian curvature can only be adapted by a stretchable display panel. Other displays are almost impossible to achieve, even if they are flexible. In this work, we designed a stretchable stacking structure and a 3D deformation process to realize the dome‐shape samples, with reference to the commercial 3D‐shape displays. And a blue‐light 3D scanning method was applied to measure the length change and area change of the dome‐shape samples. The measurement method covered in this paper can be a promising candidate for a standard method of measuring 3D deformation of stretchable displays.
