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.

Abstract: A supporting structure is described that may be applied to a flexible display panel and a display device. A flexible display panel includes a bendable region, where a bending axis corresponds to the bendable region extends in a first direction. The supporting structure includes a hollowed-out region, which has an orthographic projection on the flexible display panel completely covering the bendable region. The hollowed-out region includes a first portion having a plurality of first hollowed-out holes, and at least two second portions located at opposite sides of the first portion in the first direction and having a plurality of second hollowed-out holes. A ratio between a total area of the plurality of second hollowed-out holes and a total area of the at least two second portions is different from a ratio between a total area of the plurality of first hollowed-out holes and a total area of the first portion.

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: This application relates to a supporting structure applied to a flexible display panel and a display device. The supporting structure includes: a bendable region having a plurality of first hollowed-out holes, a bendable axis corresponding to the bendable region extending in a first direction; and at least two fixed regions at opposite sides of the bendable region in a second direction intersecting with the first direction. The fixed region has a rigid holding portion and a buffer portion having a plurality of second hollowed-out holes. The buffer portion is connected to the bendable region, and rigidity of the buffer portion is greater than or equal to rigidity of the bendable region. At least part of the rigid holding portion is provided at a side of the buffer portion away from the bendable region, and rigidity of the rigid holding portion is greater than rigidity of the buffer portion.
