In the present exemplary embodiment, a flexible display module is first provided. Referring to fig. 1 to 2, the flexible display module may include: a flexible display panel 100, a buffer film layer 200, and a flexible film layer such as a metal flexible film layer 300. The flexible display panel 100 has a bending region 500. The buffer film layer 200 is located on the lower surface of the flexible display panel 100, and includes a first buffer sub-film layer 201 and a second buffer sub-film layer 202 located in the orthographic projection area of the bending area 500 and separated from the flexible display panel 100. The tough film layer 300 is located on the lower surface of the buffer film layer 200, and includes a first tough film layer 301 and a second tough film layer 302 which are adjacent to each other, at least a part of the first tough film layer 301 and the second tough film layer 302 is located in an orthographic projection area of the bending region 500 and is fixed to the first buffer sub-film layer 201 and the second buffer sub-film layer 202 respectively, and the first tough film layer 301 and the second tough film layer 302 are located in contact with end faces of the part of the bending region 500 respectively.
Through the flexible display module, on one hand, the first buffer sub-film layer 201 and the second buffer sub-film layer 202 which are separated from each other can provide support and shielding for the flexible display panel 100 when the display module is in a flat state, so that the shock resistance of the display module is improved; on the other hand, because first buffering sublayer 201 and second buffering sublayer 202 break away from with flexible display panel 100, consequently, when flexible display module assembly is buckling, first buffering sublayer 201 and second buffering sublayer 202 and flexible display panel 100 can not produce interact's pulling force in bending zone 500, and then can promote the anti bending performance of screen, can avoid flexible display module assembly to damage at the in-process of buckling to a certain extent.
The first buffer sub-film layer 201 and the second buffer sub-film layer 202 in the orthographic projection area of the bending area 500 are separated from the flexible display panel 100, i.e., no bonding material or other mechanical methods are used for connection. The bending area 500 may be located in the display area, the non-display area, the display area, or the non-display area. At least a portion of the first and second ductile film layers 301 and 302 are fixed to the first and second buffer sub-film layers, respectively, by an Adhesive bonding, such as an OCA (optical Clear Adhesive) or other Adhesive bonding.

In one embodiment, the material of the metal flexible film 300 may include metal, specifically, the metal material may be aluminum and/or steel, for example, in one specific example, the material of the metal flexible film 300 may be selected from SUS301 stainless steel or SUS305 stainless steel, stainless steel has good ductility and high hardness, can support the flexible display module and is not easy to break when bent, and of course, other similar materials or materials satisfying the condition of the metal flexible film 300 may be possible and may be set according to the requirement.
In one embodiment, the thickness of the metal ductile film layer 300 is less than or equal to 1mm, so as to avoid the metal sheet from being broken when being bent due to the excessive thickness. Of course, in an actual application scenario, the thickness of the metal flexible film 300 may be adjusted according to the material of the metal flexible film 300, the material of the buffer film 200, the type of the flexible display panel 100, and other factors, and will not be described herein again.
In one embodiment, further comprising: support the rete, support the rete and be located flexible display panel 100 with between buffer film layer 200, because flexible display panel 100 is soft, the thin characteristic of matter, the stress concentration phenomenon appears easily in bending zone 500 especially bending line position flexible display panel 100 during buckling, supports the rete and can provide supporting role to flexible display panel 100 to disperse the stress (tensile stress or compressive stress) that flexible display module group received at the in-process of buckling better, thereby reach the guard action.
In one embodiment, the supporting film layer is a polymer organic film layer, and plays a structural supporting role on the touch screen. In the present embodiment, the material of the supporting film layer includes, but is not limited to, Polyimide (PI), Polyamide (PA), polyethylene terephthalate (PET), and polymethyl methacrylate (PMMA). The stress (tensile stress or compressive stress) that flexible display module received at the in-process of buckling can be dispersed better to the setting of supporting the rete, and the structural support to flexible display panel 100 can also be realized to the rete that supports the rete and can adopt other suitable materials. In addition, the supporting film layer may be omitted if other structures of the display module have sufficient supporting function.
In one embodiment, the buffer film layer 200 includes a foam material film layer, and the first buffer sub-film layer 201 and the second buffer sub-film layer 202 abut at the orthographic projection area. First buffering rete 201 and second buffering rete 202 are connected in metal toughness rete 300, and the alternate segregation, can provide support and shelter from for flexible display panel 100 when display module assembly exhibition flat state like this, and first buffering rete 201 and second buffering rete 202 can alternate segregation when display module assembly is in the state of buckling, do not produce stress to flexible display panel 100, and then have promoted display module assembly's anti bending property.
In one embodiment, the buffer film layer 200 includes a third buffer sub-film layer 203 and a fourth buffer sub-film layer 204 located at two sides of the orthographic projection area of the bending area 500, wherein a predetermined gap is formed between the first buffer sub-film layer 201 and the third buffer sub-film layer 203; the second buffer sub-film layer 202 and the fourth buffer sub-film layer 204 are separated by a predetermined gap. The clearance sets up and has avoided buffer film layer 200 to take place deformation and produce stress when buckling for difficult flexible display module assembly that causes damages in the process of buckling.
