Splitting of the mechanical neutral plane is a promising concept for foldable displays because it reduces the folding stress in each layer of the display. We verified the splitting concept experimentally and revealed a linear relation between the position of the neutral plane and the logarithm of the adhesive's elastic modulus. As the modulus decreased, the position of the neutral plane approached that of perfect splitting. Based on the neutral-plane splitting concept, we developed 5.5-inch FHD foldable active-matrix organic light-emitting diode (AMOLED) displays, which endured 150k inward folding cycles with a radius of 3 mm and 150k outward folding cycles with a radius of 5 mm. |
