With the development of display technology, foldable display products become a focus of attention, especially flexible foldable products, and have become a popular trend in the development of electronic products. However, in the case of the current flexible folding products, a supporting plate with a Pattern structure (Pattern structure) is usually disposed on the back of the display panel to improve the resilience and flatness of the flexible folding product when unfolded. After the research of the inventor, the inventor finds that the rigidity of the bending area provided with the Pattern structure of the existing support plate is lower, the rigidity of the support area is higher, and the rigidity change at the junction of the bending area and the support area is mutated, so that the stress generated by the support plate in the bending process is concentrated at the junction, and the support plate is easy to break at the junction of the bending area and the support area.
