Abstract: This disclosure provides a supporting structure disposed at a side of the flexible display panel and at least including a first bendable region, and a display device. A bending axis corresponding to the first bendable region extends in a first direction. The first bendable region has a plurality of first primary bending regions and a plurality of first deformation compensation regions alternately arranged in the first direction. The first primary bending region includes a plurality of first primary strip-shaped holes arranged in an array, and the first primary strip-shaped holes extend in the first direction. The first deformation compensation region includes a plurality of groups of first hollowed-out patterns arranged in an array. Each group of first hollowed-out patterns is formed by combining a plurality of hollowed-out holes, and at least two of the plurality of hollowed-out holes are different in a shape or an extending direction.

Abstract: Embodiments of the present disclosure provide a display module, including: a flexible panel, a first group of film layers attached to a light-emitting side of the flexible panel, and a second group of film layers attached to a non-light-emitting side of the flexible panel away from the light-emitting side. The display module is capable of being folded to a curved plate, such that at least a portion of an orthographic projection of the display module on a first plane perpendicular to the curved plate has a shape of a water-drop profile comprising a neck portion and a body portion. At least a portion of orthographic projections, on the first plane, of two opposite ends of the display module forms the neck portion, and an orthographic projection, on the first plane, of a middle portion of the display module between the two opposite ends forms the body portion.
