Abstract
A foldable display has multiple layers, including at least a display layer that creates the display that users see when looking at the foldable display and a stiff support layer that provides the display layer with support despite the foldable nature of the display. An adhesive layer binds the display layer to the stiff support layer. The stiff support layer has a stiffness that is at least six times greater than the stiffness of the adhesive layer and at least six times greater than the stiffness of the display layer. Given the foldable nature of the display, there is typically a hinge system below part of the display. In situations in which pressure is applied to the foldable display (e.g., by a user's finger or stylus), the stiffness of the stiff support layer prevents the display from being damaged despite the presence of the hinge system.
