[0037] The embodiments of the present application provide a flexible display module and a display device. The flexible display module and the display device in the embodiments of the present application will be described in detail below with reference to the drawings. Without conflict, the features in the following embodiments may be supplemented or combined with each other.

[0038] The embodiments of the present application provide a flexible display module. As Figure 1As shown, the flexible display module includes a flexible display screen 10, a support structure 20, and a bending assembly 30. The support structure is located on the back surface of the flexible display screen 10. The flexible display screen 10 includes a display surface and a back surface opposite to the display surface. The bending assembly 30 is located on a side of the support structure 20 away from the flexible display screen 10.

[0039] The flexible display module has three states: an unfolded state, a first bending state, and a second bending state. Figures 1 to 4 is a schematic diagram of the flexible display module in the unfolded state; Figure 5 and Figure 7 is a schematic diagram of the flexible display module in the first bending state; Figures 7 to 9 is a schematic diagram of the flexible display module in the second bending state.

[0040] As Figures 2 to 4 shown, the flexible display screen 10 includes at least three non-bending portions 11 and bending portions 12 located between two adjacent non-bending portions 11, and the at least three non-bending portions 11 are arranged side by side. The flexible display screen 10 includes a first end 101 and a second end 102. In the unfolded state, the direction from the first end 101 to the second end 102 intersects with the arrangement direction of the at least three non-bending portions 11. The arrangement direction of the at least three non-bending portions 11 is the first direction X, and the direction from the first end 101 to the second end 102 is the second direction Y. The bending assembly 30 includes at least three bending members 31 and a connecting member 32. The orthographic projection of one bending member 31 on the flexible display screen 10 is located on one non-bending portion 11; two adjacent bending members 31 are connected by the connecting member 32, and the bending member 31 can rotate relative to the connecting member 32 along the direction from the first end 101 to the second end 102, so that the bending portion 12 bends with the support structure 20. After all the bending members 31 are bent, all the non-bending portions 11 are located on the same side of each bending portion 12, causing the flexible display module to change to the first bending state, as Figure 5 and Figure 6 shown. The bending member 31 can be bent and drive the support structure 20 and the flexible display screen 10 to bend, so that the first end 101 approaches the second end 102, and further the flexible display module is in a ring shape or a part of a ring shape, causing the flexible display module to change to the second bending state. As Figure 7 and Figure 9 shown, the flexible display module is in a part of a ring shape after bending.

[0041] When the flexible display module provided by the embodiment of the present application needs to be bent, the bending member 31 can be rotated relative to the connecting member 32 first, and then the bending portions of the flexible display screen 10 and the supporting structure are bent, so that the non-bending portions 11 are located on the same side of each bending portion 12. In this way, the size of the flexible display module in the direction perpendicular to the direction from the first end 101 to the second end 102 is reduced; then the bending member 31 is bent to drive the supporting structure 20 and the flexible display screen 10 to bend, so that the flexible display module is in a ring shape or a part of a ring shape. In this way, the user can wear the flexible display module on the wrist in the bent state, which is convenient for the user to carry; in the unfolded state of the flexible display module, the display area of the flexible display screen is large, and the supporting structure can support the flexible display screen to ensure its flatness.

[0042] In one embodiment, the first direction X is perpendicular to the second direction Y.

[0043] In one embodiment, as Figure 5 With Figure 6 As shown, the flexible display screen 10 includes four non-bending portions 11 and three bending portions 12. The four non-bending portions 11 are respectively: non-bending portion 111, non-bending portion 112, non-bending portion 113 and non-bending portion 114; the three bending portions 12 are respectively: bending portion 121, bending portion 122 and bending portion 123. The first direction X is perpendicular to the second direction Y; the sizes of the non-bending portions 11 in the arrangement direction of the four non-bending portions 11, that is, the first direction X, are the same. In this way, the appearance of the flexible display module is more beautiful after folding, and the width of the flexible display module after bending is smaller, making it easier to carry. During the folding process of the flexible display module, as Figure 10 As shown, first bend the bending portions 121 and 123 on both sides. The bending of the bending portion 121 drives the non-bending portion 111 and the part of the supporting structure opposite to the non-bending portion 111 to bend relative to the non-bending portion 112. The bending of the bending portion 123 drives the non-bending portion 114 and the part of the supporting structure opposite to the non-bending portion 114 to bend relative to the non-bending portion 113, and the non-bending portion 111 and the part of the supporting structure opposite to the non-bending portion 111, and the non-bending portion 114 and the part of the supporting structure opposite to the non-bending portion 114 are bent to the same side of the non-bending portion 112; then bend the bending portion 122, so that the non-bending portion 112 and the part of the supporting structure opposite to the non-bending portion 112 bend relative to the non-bending portion 113, so that the non-bending portion 111 and the part of the supporting structure opposite to the non-bending portion 111, and the non-bending portion 114 and the part of the supporting structure opposite to the non-bending portion 114 are opposite, as Figure 5 With Figure 6 As shown. By Figure 5 And Figure 6It can be seen that after each bending member 31 is bent, each non-bending portion is located on the same side of each bending portion: the non-bending portions 111, 112, 113 and 114 are located on the same side of the bending portion 121 toward the bending portion 122, the non-bending portions 111, 112, 113 and 114 are located on the same side of the bending portion 122 toward the bending portion 121, and the non-bending portions 111, 112, 113 and 114 are located on the same side of the bending portion 123 toward the bending portion 122. Then, the bending member 31 is bent to drive the support structure 20 and the flexible display screen 10 to bend, so that the first end 101 is close to the second end 102, and the flexible display module is annular or a part of annular, as shown. Figure 7 and Figure 9 As shown. Figure 7 and Figure 9 In the illustrated embodiment, the flexible display module is a portion of a ring.

[0044] In one embodiment, after the bending member 31 drives the support structure 20 and the flexible display screen 10 to bend, the display surface of the flexible display screen 10 is located on the outside. In this way, after the flexible display module is bent, the outside side is the display surface, and the user can obtain the information displayed on the display surface, that is, the flexible display module is equivalent to a bracelet after bending, which is more helpful to improve the user experience.

[0045] In one embodiment, the first end 101 and the second end 102 are provided with a locking structure that cooperates with each other, and after the flexible display module is bent, the first end 101 and the second end 102 can be buckled together through the locking structure. In this way, after the flexible display module is bent, the user wears it on the wrist, and the locking structure can prevent the flexible display module from falling off the user's wrist.

[0046] In one embodiment, the flexible display module includes a substrate, a driving circuit layer located on the substrate, a light emitting structure layer located on a side of the driving circuit layer away from the substrate, and an encapsulation layer located on a side of the light emitting structure layer away from the substrate. The light emitting structure layer may include a plurality of sub-pixels. The driving circuit layer flexibly includes a plurality of pixel circuits. The pixel circuits may correspond to the sub-pixels one by one, and the pixel circuits drive the corresponding sub-pixels. The display surface of the display module is the side of the flexible display module away from the substrate, and the back side of the flexible display module is the side of the flexible display module away from the encapsulation layer.

[0047] In one embodiment, the support structure 20 includes a foam layer and a heat-conducting layer located on the side of the foam layer facing the flexible display screen. That is, the support structure 20 can play a role of buffering and heat dissipation, and can also support the flexible display screen. The material of the heat-conducting layer can include copper, stainless steel, etc.

[0048] In one embodiment, the support structure 20 further includes an adhesive layer on the side of the heat-conducting layer facing the flexible display screen, and the support structure 20 is fixed to the flexible display screen 10 through the adhesive layer.

[0049] In one embodiment, as Figure 2 shown, when the flexible display module is in the unfolded state, the dimension of the flexible display screen 10 in the direction from the first end 101 to the second end 102, which is also the second direction Y, is the first dimension d2, and the dimension of the flexible display screen 10 in the direction perpendicular to the direction from the first end 101 to the second end 102, which is also the first direction X, is the second dimension d1, and the first dimension d2 is greater than the second dimension d1. With such a setting, after the flexible display module is folded into the Figure 5 state shown, the length in the second direction Y is larger. The larger length can ensure that the flexible display module can be worn on the user's wrist after being bent, and the second dimension d1 is smaller, which can make the width of the flexible display module smaller after being bent, and it is also more convenient for the user to wear on the wrist.

[0050] In one embodiment, when the flexible display module is in the second bending state, the non-bending parts can be parallel to each other, that is, the distance between adjacent non-bending parts can be equal everywhere, as Figure 6 shown. In other embodiments, the distance between two adjacent non-bending parts can gradually change. For example, in the direction from the bending part 121 to the bending part 122, the distance between the non-bending part 111 and the non-bending part 112 can gradually decrease, and the distance between the non-bending part 113 and the non-bending part 114 can gradually decrease; or in the direction from the bending part 121 to the bending part 122, the distance between the non-bending part 111 and the non-bending part 112 first gradually decreases and then remains unchanged, and the distance between the non-bending part 113 and the non-bending part 114 first gradually decreases and then remains unchanged.

[0051] In one embodiment, as Figure 11 and Figure 12As shown, the bending member 31 includes a plurality of bending structures 312 and a plurality of connecting structures 311. The plurality of connecting structures 311 are arranged at intervals in the direction from the first end to the second end, that is, the second direction Y. Both ends of the same bending structure 312 are respectively connected to two adjacent connecting structures 311, and two adjacent bending structures 312 in the second direction Y are respectively connected to the same connecting structure 311. The bending structure 311 can rotate relative to the connecting structure 311 connected thereto in a direction perpendicular to the direction from the first end to the second end, that is, the first direction X. With such a setting, when the bending member 31 is bent, two adjacent bending structures 312 respectively rotate relative to the connecting structures 311 connected thereto in the first direction X, so that the included angle between two adjacent bending structures 312 changes, and thus the plurality of bending structures 312 of the bending member 31 can be integrally in a ring shape or a part of a ring shape.

[0052] In one embodiment, the bending structure 312 can be a strip-shaped plate structure. In its length direction, one end of the bending structure 312 is connected to one connecting structure 311, and the other end is connected to another connecting structure 311.

[0053] In one embodiment, as Figure 11 and Figure 12 shown, both ends of the connecting structure 311 are respectively connected with bending structures 312. In this way, the bending member 31 has better stability and is not easily deformed.

[0054] In one embodiment, as Figure 11 shown, the connecting structure 311 includes a sleeve 314 and a ball 315 located in the sleeve 314. The ball 315 can rotate in the sleeve 314. Both ends of the bending structure 312 are respectively connected to the ball 315 of one connecting structure 311 in a relatively rotatable manner. And the adjacent end portions of two adjacent bending structures 312 in the direction from the first end to the second end are respectively connected to the same ball 315. Thus, when the bending member 31 is bent, two adjacent bending structures 312 respectively rotate relative to the balls 315 connected thereto, so that the included angle between two adjacent bending structures 312 changes, and thus the plurality of bending structures 312 of the bending member 31 can be integrally in a ring shape or a part of a ring shape.

[0055] In one embodiment, as Figure 11 shown, the connecting structure 311 includes two balls 315 located in the sleeve 314, and the two balls 315 are arranged at intervals in the first direction X. The two balls 315 are respectively connected to a bending structure 312, and the two bending structures are opposite to each other in the first direction X.

[0056] In one embodiment, asFigure 11 As shown, the bending member 31 further includes a connecting rod portion 318, and the connecting rod portion 318 is fixedly connected to the ball 315. The rotation of the ball 315 drives the rotation of the connecting rod portion 318. The bending structure 312 is rotatably connected to the connecting rod portion 318. For example, the bending structure 312 may be provided with a through hole, and the connecting rod portion 318 passes through the through hole and can rotate within the through hole.

[0057] In another embodiment, as Figure 12 As shown, the connecting structure 311 includes a rotating shaft 316. Two ends of the bending structure 312 are respectively connected to one rotating shaft 316 and can rotate relative to the rotating shaft 316. In this way, when the bending member 31 is bent, two adjacent bending structures 312 respectively rotate relative to the rotating shafts 316 connected thereto, and the included angle between the two adjacent bending structures 312 changes, so that a plurality of bending structures 312 of the bending member 31 can be integrally in a ring shape or a part of a ring shape. The bending structure 312 may be provided with a through hole, and the rotating shaft 316 passes through the through hole and can rotate within the through hole.

[0058] In one embodiment, as Figure 12 As shown, the connecting structure 311 further includes a sleeve 317. The rotating shaft 316 passes through the sleeve 317, and both ends are exposed from the sleeve 317. Among the two bending structures 312 connected to the end of the same rotating shaft 316, the bending structure 312 located inside abuts against the sleeve 317, so that the sleeve 317 can prevent the bending structure 312 from moving.

[0059] In one embodiment, the connecting member includes a plurality of sub-connecting members, and in the direction from the first end to the second end, that is, the second direction Y, the plurality of sub-connecting members are arranged at intervals. With such a setting, when the flexible display module is bent, since the plurality of sub-connecting members are arranged at intervals in the second direction Y, the sub-connecting members do not hinder the bending of the flexible display module.

[0060] In one embodiment, as Figure 13 As shown, the support structure 20 includes a plurality of support portions 21. When the flexible display module is in an unfolded state, the plurality of support portions 21 are arranged at intervals in the direction from the first end 101 to the second end 102, that is, the second direction Y. With such a setting, when the flexible display module is bent, the wrinkles generated by the support structure 20 can be improved. Figure 13 In the embodiment shown, the support portion 21 is rectangular. In other embodiments, the support portion 21 may also be diamond-shaped, circular, oval, irregular in shape, etc.

[0061] In one embodiment, as Figure 13As shown, the support structure 20 is provided with a plurality of through-hole groups 22, and each through-hole group 22 includes a plurality of through-holes 221. When the flexible display module is in the unfolded state, the plurality of through-hole groups 22 are arranged at intervals in a direction perpendicular to the direction from the first end 101 to the second end 102, that is, in the first direction. Each through-hole group 22 may include at least one column of through-holes 221 arranged at intervals in the second direction Y. Figure 13 In the illustrated embodiment, each through-hole group 22 includes three columns of through-holes 221 arranged at intervals in the second direction Y. When the flexible display module is switched from the unfolded state to the first bent state, the arrangement of the plurality of through-hole groups 22 can improve the wrinkles generated by the support structure 20.

[0062] In one embodiment, the display screen further includes a polarizer located on the light-emitting structure layer, and the polarizer is a flexible structure.

[0063] In one embodiment, the display screen further includes a cover plate located on the light-emitting structure layer, and the cover plate is a flexible cover plate.

[0064] In one embodiment, the size of the flexible display module may be as follows: when the flexible display module is in the unfolded state, its size in the first direction X is 80 mm, and its size in the second direction is 166 mm; when the flexible display module is Figure 10 in the bent state as shown, its size in the direction from the bent portion 121 to the bent portion 123 is 49.5 mm, the outer diameter after bending of the bent portion 121 and the bent portion 123 may be 6.5 mm, the distance between the first end 101 and the outer side surface of the bent portion 121 is 16.25 mm, and the distance between the second end 102 and the outer side surface of the bent portion 123 is 16.25 mm; when the flexible display module is in the second bent state, its width is 23.26 mm, the outer diameter is 86 mm, the inner diameter is 59 mm, and the thickness is 13.5 mm; when the bending member of the flexible display module is as Figure 11 shown, the diameter of the ball 315 is 2 mm, and the size of the connecting structure 311 in the first direction X is 5 mm.

[0065] The embodiment of the present application further provides a display device. The display device includes the flexible display module described in any of the above embodiments. The display device is a flexible display device.
