Abstract: A flexible OLED display device includes a flexible display panel and a support member. The flexible display panel includes an active area, an extension portion and a bending portion connecting the active area and the extension portion. The support member is located between the active area and the extension portion. The active area, the support member and the extension portion are stacked, and a first distance is set between the support member and the bending portion in an extending direction parallel to the extension portion. The bending portion is substantially of a semicircular shape, and an inner radius of the semicircular shape is equal to a sum of a half of a thickness of the support member and a third distance between an upper surface of the support member and a lower surface of the active area, and the third distance is less than the thickness of the support member.

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.
