The object of the present invention and the technical problems solved thereby can be further achieved by the following technical measures.

Specifically, as shown in fig. 4, the first body 1 and the second body 2 each include a mounting area 11 and a supporting area 12 on a side facing the first side surface 36, a distance from the supporting area 12 to the first plane is greater than a distance from the fixing area 31 to the first plane, the mounting area 11 is attached to the fixing area 31, a supporting protrusion 41 is formed on a side of the supporting area 12 away from the mounting area 11, and the supporting protrusion 41 serves as the supporting portion 4.

Wherein, the installing zone 11 is connected with the first side 36 corresponding to the fixing zone 31, and the flexible display module 3 is not connected with the supporting zone 12, under the folding condition, the fixing zone 31 is located between the first body 1 and the second body 2, and the partial bending zone 32 is located between the two supporting zones 12, wherein, the supporting part 4 has a preset distance from the installing zone 11, and the distance between the supporting zone 12 and the first plane is greater than the distance between the installing zone 11 and the first plane, when the display device is in the folding condition, a gap is formed between the two fixing zones 31 of the flexible display module 3, and the flexible display module is not completely attached. Further, the mounting area 11 and the first plane may be made parallel to each other in the folded state, and as shown in fig. 3 and 4, a height difference may be formed at the connection of the support area 12 and the mounting area 11, or the end of the support area 12 connected to the mounting area 11 is located on the same surface as the mounting area 11, while the height of the support area 12 is gradually reduced in a direction away from the mounting area 11, and the support protrusion 41 is formed at the farthest position of the support area 12 from the mounting area 11. The support portion 4 may be a support protrusion 41, that is, the support portion 4 protrudes from the surface of the support region 12, wherein the support portion 4 may be in a strip shape, and preferably, the length direction of the support portion 4 is parallel to the bending center line 33, and the bending center line 33 is parallel to the boundary line 35 and the boundary line 34, and in this case, the shape of the bending region 32 is easier to control. The support portion 4 and the bending center line 33 may not satisfy the straight line condition, and are not particularly limited herein. Further, the support portion 4 may include a plurality of support protrusions 41, and the plurality of support protrusions 41 may be located on a straight line, which may be parallel to the bending center line 33.

Specifically, the first body 1 and the second body 2 both include an installation area 11 and a support area 12 on a side facing the first side surface 36, a distance from the support area 12 to the first plane is greater than a distance from the fixing area 31 to the first plane, the installation area 11 is attached to the fixing area 31, as shown in fig. 1 and 2, a distance from the support area 12 to the first plane gradually increases along a first direction, and one end of the support area 12 away from the installation area 11 serves as the support portion 4.

Wherein, the distance between the first plane and the first direction support area 12 gradually increases, and at this moment, the one end of the support area 12 far away from the installation area 11 can be used as the support portion 4, so that the one end of the support area 12 far away from the installation area 11 is formed with an edge, and the edge can support the first side surface 36, and at this moment, the support portion 4 and the first side surface 36 are in line contact. Alternatively, as shown in fig. 2, a partial region of one end of the support region 12 away from the mounting region 11 is used as the support portion 4, and is in contact with a partial region of the first side surface 36 to press the first side surface 36, and at this time, the contact area between the first side surface 36 and the support portion 4 is large. The area of the support area 12 not pressing the first side surface 36 can be attached to the first side surface 36, and the area of the support area 12 not pressing the first side surface 36 is curved, and the curved surface is attached to the first side surface 36 only without generating interaction force according to the shape design of the drop-shaped bending area 32. When the supporting region 12 is a plane, the manufacturing process is simple, and a gap can be formed between the first side surface 36 and the region of the supporting region 12 not attached to the first side surface 36, so that the elongation of the folded region 3211 in the thickness direction is further reduced.

In particular, a gap is formed between the support area 12 and the first side 36 between the fixing area 31 and the support portion 4.

In order to ensure the reliability of the flexible display module 3, i.e. further reduce the elongation of the flexible display module 3 in the thickness direction thereof, a gap should be formed between the area between the fixing region 31 and the supporting portion 4 and the first side surface 36.

Specifically, as shown in fig. 1 and 2, one end of the support portion 4 facing the first side surface 36 is formed with a support arc surface.

Wherein, the centre of a circle of supporting the cambered surface is located the one side that the first side 36 was kept away from to the supporting cambered surface, supports the cambered surface through setting up and can make supporting cambered surface and 36 smooth contact of first side, avoids supporting part 4 to scrape flexible display module 3 bad. Under the condition that the distance between the supporting area 12 and the first plane is gradually increased along the first direction, as shown in fig. 1 and fig. 2, a supporting arc surface is formed on one side of the supporting area 12, which is far away from the fixing area 31, instead of forming an edge, so that the edge is prevented from scratching the flexible display module 3.

Specifically, as shown in fig. 3, an area of the first side surface 36 pressed by the supporting portion 4 is a pressing area, and an included angle between a plane passing through the connecting line and any point on the pressing area and the first plane is greater than or equal to 8 ° and less than or equal to 15 °, where the connecting line is a junction between the fixing area 31 and the bending area 32.

Wherein, the extrusion area is strip-shaped, and the length direction thereof is parallel to the bending central line 33. A plane passing through the connecting line and any point on the pressing area is set as a second plane, wherein an included angle between the second plane and the first plane is related to a distance from one end of the supporting part 4 facing the first plane to the first plane and a distance from the supporting part 4 to the fixing area 31. As shown in fig. 3, the included angle between the second plane and the first plane is ≦ B, wherein ≦ B is preferably equal to or less than 8 ° and equal to or less than 15 °. When the included angle between the second plane and the first plane is smaller than 8 °, the pressing force applied to the first side surface 36 by the supporting portion 4 is relatively large, so that the transition fluctuation of the area of the first side surface 36 between the pressing area and the bending central line 33 is relatively large, and the flexible display module 3 in the area is prone to glue failure. If the included angle between the second plane and the first plane is too large, the transition fluctuation between the outward folding region 3211 and the inward folding region 3212 is still large, and the outward folding region 3211 is still prone to glue failure. Among them, angle B is preferably 11.5 °.

Specifically, as shown in fig. 4, a distance between an orthogonal projection of the crush zone on the first plane and an orthogonal projection of the connecting line on the first plane is greater than or equal to 5mm and less than or equal to 24mm.

As shown in fig. 4, a distance between an orthographic projection of the extrusion region on the first plane and an orthographic projection of the connecting line on the first plane is L, and in order to effectively avoid glue failure in the folded region 3211, L should be greater than or equal to 5mm and less than or equal to 24mm.

Specifically, as shown in fig. 4, the distance from the vertex to the first plane is 3mm or more and 5mm or less.

Wherein, the distance of summit apart from first plane is R, and when R more than or equal to 3mm less than or equal to 5mm, the effect of preventing splitting is better in this application. In addition, the length of the bending region 32 in the first direction is 40mm or more and 50mm or less.

Specifically, as shown in fig. 5, the flexible display module 3 includes a cover plate 371, a first optical adhesive layer 372, a touch layer 373, a display panel 374, a second optical adhesive layer 375, and a support layer 376, which are sequentially stacked, where a side of the support layer 376 away from the second optical adhesive layer 375 is used as the first side surface 36.

Wherein, the supporting layer 376 can be made of a metal material, and specifically can be SUS, in the prior art, because the rigidity of the supporting layer 376 is stronger than that of the cover plate 371, when the outward folding region 3211 of the flexible display module 3 is bent, the outward folding region 3211 protrudes toward the first plane, so that the elongation of the first optical adhesive layer 372 below the cover plate 371 is the largest, and the cracking is most likely to occur. And this application can effectively avoid the first optics glue film 372 fracture of outer book district 3211 through setting up the shape of the 3 bending zones 32 of supporting part 4 control flexible display module. Wherein the support layer 376 is fixedly connected with the first body 1 and the second body 2. The flexible display module 3 includes fpc (flexible circuit board), cof (chip on film), and the like in addition to the above structure.

On the other hand, an embodiment of the present invention further provides an electronic device, where the electronic device includes: the display device of any preceding embodiment. Therefore, the present embodiment includes the advantages of any of the above embodiments, which are not described herein again.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and shall cover the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
