Structural optimization method of foldable active-matrix organic light-emitting diode panel based on mechanical theory

The multineutral plane phenomenon of foldable panel can obviously reduce the strain of the active-matrix organic light-emitting diode (AMOLED) panel after being bent, but it also complicates the optimization of the panel structure. Considering the force balance at the axis of symmetry after the panel was folded, this paper established the basic theory of AMOLED panel structure optimization, which indicated the direction of structure optimization of the panel. Then, the theory was validated by numerical simulation. It can be used to guide the structural design of the foldable panel.
