Neutral‐plane splitting is essential for the durability and the usability of foldable displays. In this study, we use folding stiffness measurements and finite element method simulations to establish the relationship between split neutral planes’ positions and folding stiffness. Based on the relationship, the folding stiffness is predicted from the split neutral‐planes position.
