Abstract
A foldable display stack for an electronic device comprising a covering structure comprising a first cover layer and a polarizing layer, a second cover layer, and a displaying structure arranged between the covering structure and the second cover layer. A first adhesive layer attaches the covering structure to the displaying structure. A second adhesive layer attaches the displaying structure to the second cover layer. The displaying structure comprises a plurality of layers and the neutral plane of the foldable display stack. The first cover layer is arranged at a first distance from the neutral plane, in a first direction perpendicular to the neutral plane. The second cover layer is arranged at a second distance from the neutral plane, in a second direction opposite to the first direction. The first distance and the second distance are equal.
