Abstract
Foldable AMOLED panel are getting more attention due to portability and size extensibility. If there is a drop or collision impact during use, it is easy to cause panel crack or peeling, which has become a major problem affecting the development of foldable AMOLED panel. We designed the panel impact device and tested the anti‐impact energy and failure mode of the foldable AMOLED panel. Meanwhile, the stress process in the impact process is analyzed in detail based on finite element mechanics simulation. In addition, we also propose schemes to improve the anti‐impact performance of the foldable AMOLED panel through systematic anti‐impact experiments and simulation analysis, including increasing the bending stiffness of the foldable module and optimizing the pattern design of metal supporting material.
