Splitting of the mechanical neutral plane is a promising concept for foldable displays because it reduces the
folding stress and stiffness of the display. We verified the concept experimentally and developed 5.5-inch full high-
definition foldable AMOLED displays, which endured 150 k inward folding cycles with folding radius of 3 mm.
