Embodiment Construction

[0046] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0047] refer to figure 1 with figure 2 The schematic diagram of the structure of the flexible support plate in the related art shown, in order to achieve a smaller bending radius and reduce the stress of the film layer after bending, a patterned flexible support plate will be used, that is, in the middle of the bending of the flexible support plate Some patterns are designed and through holes 3 are formed to increase the du...

Abstract

The invention relates to the technical field of display and provides a flexible supporting plate and a flexible display device. The flexible support plate comprises an open pore area and at least onesolid area arranged on at least one side of the open pore area, wherein a plurality of through holes are formed in the perforated area, the perforated area comprises a middle area and a transition area, the transition area is arranged between the middle area and the entity area, and the width of the transition area is reduced along with the increase of the distance between the transition area andthe middle area. When the flexible support plate is bent, deformation of the transition area is gradually changed, and the stress is also gradually changed without sudden change, i.e., the stress is uniformly changed, so that hard corner bending caused by sudden change of the stress during bending is avoided, and problems of film separation and cracks are avoided; in addition, the flexible displaypanel can be applied to a flexible display device with a small bending radius.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible support plate and a flexible display device comprising the flexible support plate. Background technique [0002] A flexible OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device includes a flexible display panel, on which a glass cover is pasted, and the glass cover protects the flexible display panel and maintains the strength of the flexible display panel. Because the glass cover has high hardness and low toughness and is brittle after being stretched, the surface of the foldable flexible display panel needs to be protected by a cover film. In order to ensure the strength of the flexible display panel, a stainless steel support plate is usually attached to the back of the flexible display panel. After the flexible display panel is bent, the neutral layer changes due to the stress change of the film layer, and film layer separation...
