P‐5.25: Mechanical Design and Simulation Design of Support Layer of the Crossed Foldable Display Module

In this paper, the concept of crossed foldable display module is proposed as follows: there are two foldable axes, and the two foldable axes intersect vertically. In order to realize the crossed foldable display, it needs to be designed in terms of modules, hinges and so on, especially the module support layer in the intersection area. In this paper, the steps of structural design, numerical simulation and sample verification are used to obtain two kinds of support layers suitable for crossed foldable modules, which can be folded hundreds of thousands of times without failure in the whole module test verification, providing a new form for flexible display.
