[0073] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0074] In the related art, reference Figure 1 , the curved display device 10 may include an OLED display panel 101 and a supporting device 102 for supporting the OLED display panel 101. The supporting device 102 may be a curved strip structure, and the supporting device 102 has a fixed curvature. After the OLED display panel 101 is fixedly connected to the supporting device 102, the supporting device 102 may apply a certain force to the OLED display panel 101 to bend the OLED display panel. In addition, in order to obtain OLED display panels with a variety of different degrees of curvature, supporting devices with different curvatures may be selected to be fixedly connected to the OLED display panel, thereby obtaining display devices with different curvatures.

[0075] However, since the curvature of each supporting device in the related art is a fixed value, the curvature of the obtained curved display device is a fixed curvature, and the flexibility of use is low.

[0076] Figure 2 201 is a schematic diagram of a supporting device provided in an embodiment of the present application. The supporting device 201 can be arranged on the back side of the bendable structure to support the bendable structure. Figure 2 It can be seen that the supporting device 201 may include: a plurality of sequentially connected adjustment structures 2011, each of which may be used to adjust the flexible structure ( Figure 1The back side of the flexible structure 2011 is connected to the back side of the flexible structure 2011, and any two adjacent adjustment structures 2011 can rotate relative to each other. Wherein, any two adjacent adjustment structures 2011 can rotate relative to each other in a plane perpendicular to the back side of the flexible structure.

[0077] Since the support device 201 is disposed on the back side of the bendable structure, the support device 201 can apply a force to the bendable structure to bend the bendable structure. For example, the curvature of the bendable structure is the same as the curvature of the support device 201. Furthermore, since any two adjacent adjustment structures 2011 in the support device 201 can rotate relative to each other, the curvature of the support device 201 can be adjusted by adjusting the rotation angle between each adjustment structure 2011 and the adjacent adjustment structure 2011, thereby achieving the adjustment of the curvature of the bendable structure.

[0078] In the embodiment of the present application, the bendable structure may be a flexible display panel. By arranging the support device 201 on the back side of the flexible display panel, the curvature of the flexible display panel can be adjusted by adjusting the curvature of the support device 201, thereby adjusting the curvature of the display device. Since the curvature of the display device is not a fixed curvature, it has high flexibility in use. Of course, the bendable structure may also be other bendable structures, for example, the bendable structure may be a flexible plate-like structure, which is not limited in the embodiment of the present application.

[0079] In the embodiment of the present application, the relative rotation angle of each two adjacent adjustment structures 2011 in the support device 201 can be a fixed angle, and the curvature of each part of the support device can be the same. Thus, the force exerted by each adjustment structure 2011 in the support device 201 on the bendable structure can be the same, so that the curvature of each part of the bendable structure is the same.

[0080] In summary, an embodiment of the present application provides a supporting device, which includes a plurality of adjustment structures connected in sequence, each adjustment structure is used to connect to the back side of a bendable structure, and any two adjacent adjustment structures among the plurality of adjustment structures can rotate relative to each other. Therefore, the curvature of the supporting device can be adjusted by adjusting the rotation angle between each adjustment structure and the adjacent adjustment structure, thereby adjusting the curvature of the bendable structure connected to the supporting device, and the use flexibility of the bendable structure is high.

[0081] It should be noted that the bendable structure may have a back side and a front side opposite to each other. By adjusting the rotation direction of each adjustment structure 2011 in the support device 201, the bendable structure may be bent toward the back side thereof, or may be bent toward the front side thereof.

[0082] For example, assuming that the bendable structure is a flexible display panel, the back side of the flexible display panel is the non-light emitting side, and the front side is the light emitting side. The support device 201 is arranged on the back side of the flexible display panel, and the flexible display panel can be made into a convex display panel or a concave display panel by adjusting the adjustment structure 2011 in the support device. The middle part of the light emitting side of the convex display panel is convex, and the middle part of the light emitting side of the concave display panel is concave.

[0083] Figure 3 yes Figure 2 The partial structural diagram of the supporting device is shown in FIG. Figure 3 Each adjustment structure 2011 may include: a fixed member 20111 and a rotating member 20112. The fixed member 20111 may be connected to the rotating member 20112 to fixedly connect the rotating member 20112 to the bendable structure. In addition, the rotating member 20112 may be rotatably connected to the rotating member 20112 in the adjacent adjustment structure 2011 to achieve relative rotation of the two adjacent adjustment structures 2011.

[0084] Figure 4 Schematic diagram of a rotating member provided in an embodiment of the present application. Figure 4 The rotating member 20112 may include: a main structure 201121, and a first lug 201122 and a second lug 201123 arranged on both sides of the main structure 201121.

[0085] The main structure 201121 may be provided with a first through hole 201121a, and the fixing member 20111 may pass through the first through hole 201121a and be fixedly connected to the bendable structure. Figure 5 The first lug 201122 can be rotatably connected to the second lug 201123 in the adjacent adjustment structure 2011 to achieve a rotatable connection of the adjacent rotating member 20112.

[0086] refer to Figure 4 It can also be seen that each of the first lug 201122 and the second lug 201123 has a first side surface and a second side surface relative to each other, and the second side surface is close to the first through hole 201121a relative to the first side surface, and the first side surface and the second side surface are both parallel to the axial direction of the first through hole 201121a.

[0087] refer to Figure 4, for the first lug 201122, the first side surface 201122a of the first lug 201122 is opposite to the second side surface 201122b of the first lug 201122, and the second side surface 201122b of the first lug 201122 is closer to the first through hole 201121a relative to the first side surface 201122a of the first lug 201122. The first side surface 201122a of the first lug 201122 and the second side surface 201122b of the first lug 201122 are both parallel to the axial direction of the first through hole 201121a. For the second lug 201123, the first side surface 201123a of the second lug 201123 is opposite to the second side surface 201123b of the second lug 201123, and the second side surface 201123b of the second lug 201123 is closer to the first through hole 201121a relative to the first side surface 201123a of the second lug 201123. The first side surface 201123a of the second lug 201123 and the second side surface 201123b of the second lug 201123 are both parallel to the axial direction of the first through hole 201121a.

[0088] In the examples of this application, refer to Figure 4 The first side surface 201122a of the first lug 201122 may be coplanar with the first side surface 201123a of the second lug 201123 , and the second side surface 201122b of the first lug 201122 may be coplanar with the second side surface 201123b of the second lug 201123 .

[0089] refer to Figure 4 It can also be seen that the first lug 201122 may have a second through hole 201122c, and the second lug 201123 may have a third through hole 201123c. Figure 5 Each adjustment structure 2011 may further include: a connecting member 20113. The connecting member 20113 may be used to be arranged in the second through hole 201122c of the first lug 201122 and the third through hole 201123c of the second lug 201123 in the adjacent adjustment structure 2011. The first lug 201122 may be connected to the second lug 201123 in the adjacent adjustment structure 2011 through the connecting member 20113. That is, after the first lug 201122 is connected to the second lug 201123 in the adjacent adjustment structure 2011, the connecting member 20113 may be located in the second through hole 201122c of the first lug 201122 and the third through hole 201123c of the second lug 201123.

[0090] Optional, reference Figure 6, the connecting member 20113 may be a first screw. The interior of one of the second through hole 201122c and the third through hole 201123c has threads. The first screw 20113 penetrates from the one of the second through hole 201122c and the third through hole 201123c that does not have threads and is connected to the other through hole that has threads.

[0091] As an optional implementation, refer to Figure 6 The second through hole 201122c of the first lug 201122 does not have threads, and the third through hole 201123c of the second lug 201123 has threads. Then, the first screw 20113 can be inserted from the side of the first lug 201122 away from the second lug 201123 and connected to the third through hole 201123c of the second lug 201123 in the adjacent adjustment structure 2011.

[0092] Furthermore, the diameter of the head 201131 of the first screw 20113 may be larger than the diameter of the second through hole 201122c of the first lug 201122, and the diameter of the connecting portion 201132 of the first screw 20113 may be smaller than the diameter of the second through hole 201122c of the first lug 201122. The head 201131 of the first screw 20113 can press the first lug 201122 to the second lug 201123, so that the first lug 201122 and the second lug 201123 are in close contact, thereby ensuring the reliability of the connection between adjacent adjustment structures 2011.

[0093] refer to Figure 6 It can also be seen that the side of the first lug 201122 away from the second lug 201123 may have a groove 201122d, and the diameter of the groove 201122d is larger than the diameter of the head 201131 of the first screw 20113, so that the head 201131 of the first screw 20113 can be located in the groove 201122d, thereby preventing the first screw 20113 from being loosened due to the influence of other structures, thereby ensuring the reliability of the connection between the first lug 201122 and the second lug 201123 in the adjacent adjustment structure 2011.

[0094] As another optional implementation, refer to Figure 7 The second through hole 201122c of the first lug 201122 has threads, and the third through hole 201123c of the second lug 201123 does not have threads. Then the first screw 20113 can be inserted from the side of the second lug 201123 away from the first lug 201122 and connected with the second through hole 201122c of the first lug 201122 in the adjacent adjustment structure 2011.

[0095] Furthermore, the diameter of the head 201131 of the first screw 20113 may be larger than the diameter of the third through hole 201123c of the second lug 201123, and the diameter of the connecting portion 201132 of the first screw 20113 may be smaller than the diameter of the third through hole 201123c of the second lug 201123. The head 201131 of the first screw 20113 can press the second lug 201123 onto the first lug 201122, so that the second lug 201123 is in close contact with the first lug 201122, thereby ensuring the reliability of the connection between adjacent adjustment structures.

[0096] And, reference Figure 7 The second lug 201123 may have a groove 201123d on the side away from the first lug 201122, and the diameter of the groove 201123d is larger than the diameter of the head 201131 of the first screw 20113, so that the head 201131 of the first screw 20113 can be located in the groove 201123d, thereby preventing the first screw 20113 from being loosened due to the influence of other structures, thereby ensuring the reliability of the connection between the first lug 201122 and the second lug 201123 in the adjacent adjustment structure 2011.

[0097] In the embodiment of the present application, as an optional implementation method, combined with Figure 4 and Figure 5 When the first lug 201122 is connected to the second lug 201123 in the adjacent adjustment structure 2011, the first side surface 201122a of the first lug 201122 may contact the first side surface 201123a of the second lug 201123 in the adjacent adjustment structure 2011. Figure 5 , a distance H between an axis of a first through hole 201121a in a main structure 201121 of a rotating member 20112 and an axis of a first through hole 201121a in a main structure 201121 of an adjacent rotating member 20112 is twice a distance h between the first through hole 201121a and the first side surface.

[0098] refer to Figure 8 and Fig. 9 In order to ensure reliable connection between the first lug 201122 and the second lug 201123, the first side surface 201122a of the first lug 201122 may have a protruding structure 2011221, and the first side surface 201123a of the second lug 201123 may have a groove 2011231. Figure 6 and Figure 7The protruding structure 2011221 in the first lug 201122 can be used to connect with the groove 2011231 of the second lug 201123 in the adjacent adjustment structure 2011. That is, after the first lug 201122 is connected with the second lug 201123 in the adjacent adjustment structure 2011, the protruding structure 2011221 in the first lug 201122 can be located in the groove 2011231 of the second lug 201123 in the adjacent adjustment structure 2011.

[0099] Fig.10 is a schematic diagram of a first side surface of a first lug provided in an embodiment of the present application. Fig.10 The protruding structure 2011221 may include: two protruding substructures a located on both sides of the second through hole 201122c. Fig.11 is a schematic diagram of a first side surface of a second lug provided in an embodiment of the present application. Fig.11 , the groove 2011231 may include: two sub-grooves b located on both sides of the third through hole 201123c. Each protruding substructure a of the first lug 201122 may be used to connect with a sub-groove b of the second lug 201123 in the adjacent adjustment structure 2011. That is, each protruding substructure a of the first lug 201122 may be located in a sub-groove b of the second lug 201123 in the adjacent adjustment structure 2011.

[0100] for Figure 5 The structure shown is a scene in which the first side surface 201122a of the first lug 201122 contacts the first side surface 201123a of the second lug 201123 in the adjacent adjustment structure 2011. Fig.10 The orthographic projection of each protruding substructure a on the first side surface 201122a of the first lug 201122 may be fan-shaped. Fig.11 The orthographic projection of each sub-groove b on the first side surface 201123a of the second lug 201123 may be fan-shaped.

[0101] And, reference Fig.10 and Fig.11 Since the first sector angle β of each sub-groove b can be greater than the second sector angle α of the protruding substructure a, the position of the protruding substructure a in the sub-groove b can be changed. This can achieve the angle change between the rotating member 20112 and the rotating member 20112 in the adjacent adjustment structure 2011, thereby achieving the curvature adjustment of the support device 201.

[0102] As another optional implementation, refer to Fig.12, the second side surface 201122b of the first lug 201122 can contact the second side surface 201123b of the second lug 201123 in the adjacent adjustment structure 2011. Fig.12 , the distance between the axis of the first through hole 201121a in the main structure 201121 of the rotating member 20112 and the axis of the first through hole 201121a in the main structure 201121 of the adjacent rotating member 20112 is less than twice the distance between the first through hole 201121a and the first side surface.

[0103] refer to Fig.13 In order to ensure reliable connection between the first lug 201122 and the second lug 201123, the second side surface 201122b of the first lug 201122 may have a protruding structure 2011221, and the second side surface 201123b of the second lug 201123 may have a groove 2011231, and the protruding structure 2011221 in the first lug 201122 may be used to connect with the groove 2011231 of the second lug 201123 in the adjacent adjustment structure 2011. That is, after the first lug 201122 is connected with the second lug 201123 in the adjacent adjustment structure 2011, the protruding structure 2011221 in the first lug 201122 may be located in the groove 2011231 of the second lug 201123 in the adjacent adjustment structure 2011.

[0104] Fig.14 is a schematic diagram of a second side surface of a first lug provided in an embodiment of the present application. Fig.14 The protruding structure 2011221 may include: two protruding substructures a located on both sides of the second through hole 201122c. Fig.14 is a schematic diagram of a second side surface of a second lug provided in an embodiment of the present application. Fig.15 , the groove 2011231 may include: two sub-grooves b located on both sides of the third through hole 201123c. Each protruding substructure a of the first lug 201122 may be used to connect with a sub-groove b of the second lug 201123 in the adjacent adjustment structure 2011. That is, each protruding substructure a of the first lug 201122 may be located in a sub-groove b of the second lug 201123 in the adjacent adjustment structure 2011.

[0105] Of course, for Fig.12 The structure shown is a scene in which the second side surface 201122b of the first lug 201122 contacts the second side surface 201123b of the second lug 201123 in the adjacent adjustment structure 2011. Fig.14The orthographic projection of each protruding substructure a on the second side surface 201122b of the first lug 201122 may be fan-shaped, and the orthographic projection of each sub-groove b on the second side surface 201123b of the second lug 201123 may be fan-shaped. In addition, the first fan-shaped angle β of each sub-groove b may be greater than the second fan-shaped angle α of the protruding substructure a, so as to achieve the angle change between the rotating member 20112 and the rotating member 20112 in the adjacent adjustment structure 2011, thereby achieving the curvature adjustment of the support device 201.

[0106] refer to Fig.16 If each adjustment structure 2011 is connected to an adjacent adjustment structure 2011, and the axis a1 of the protruding substructure a is collinear with the axis b1 of the subgroove b, the curvature of the support device 201 is the smallest within the adjustable curvature range, and the minimum curvature of the support device 201 can be 0. Fig.17 and Fig.18 , if each adjustment structure 2011 is connected to the adjacent adjustment structure 2011, the axis a1 of the raised substructure a and the axis b1 of the subgroove b are not colinear, and the end surface of the raised substructure a contacts the end surface of the groove d, the curvature of the support device 201 is the largest within the adjustable curvature range. The maximum adjustable curvature of the support device 201 is determined based on the curvature of the maximum bending degree of the bendable structure without damage. The maximum bending degree of the bendable structure depends on the characteristics of the bendable structure.

[0107] refer to Fig.16 , if each adjustment structure 2011 is connected to the adjacent adjustment structure 2011, the axis a1 of the protruding substructure a and the axis b1 of the sub-groove b are collinear, the angle γ between the first surface a2 of the protruding substructure a and the first surface a2 of the sub-groove b can be equal to the angle φ between the second surface a3 of the protruding substructure a and the first surface a3 of the sub-groove b. In this case, the protruding substructure a can rotate relative to the sub-groove b along the first direction X or the second direction Y. The first direction X and the second direction Y are opposite, and the first direction X and the second direction Y are parallel to the first side surface 201122a of the first lug 201122.

[0108] Combination Figures 16 to 18 ,because Fig.17 The first surface a2 of the raised substructure a contacts the first surface a2 of the subgroove b. Therefore, the raised substructure a can rotate relative to the subgroove b along the first direction X. Fig.18 The second surface a3 of the middle protruding substructure a contacts the second surface b3 of the sub-groove b. Therefore, the protruding substructure a can rotate along the second direction Y relative to the sub-groove b.

[0109] It should be noted that the roughness of the side where each lug contacts the other lug may be greater than the roughness threshold. By setting the roughness of the side where each lug contacts the other lug to be relatively large, the relative movement of the two lugs due to the reverse elastic force of the bendable structure can be avoided, thereby ensuring the stability of the support device 201 composed of multiple adjustment structures 2011.

[0110] Optionally, during the process of manufacturing the adjustment structure 2011, the contact surface of the lug in the adjustment structure 2011 may be processed into a frosted surface by a sandblasting process or an oxidation process to increase the roughness of the contact surface of the lug.

[0111] for Figure 5 , Figure 8 as well as Fig. 9 In the structure shown, the first side surface 201122a of the first lug 201122 contacts the first side surface 201123a of the second lug 201123 in the adjacent adjustment structure 2011, so the roughness of the first side surface 201122a of the first lug 201122 and the first side surface 201123a of the second lug 201123 in the adjacent adjustment structure 2011 can be set larger. Fig.12 as well as Fig.13 In the structure shown, the second side surface 201122b of the first lug 201122 contacts the second side surface 201123b of the second lug 201123 in the adjacent adjustment structure 2011, so the roughness of the second side surface 201122b of the first lug 201122 and the second side surface 201123b of the second lug 201123 in the adjacent adjustment structure 2011 can be set to be larger.

[0112] In the embodiment of the present application, the main structure 201121, the first lug 201122 and the second lug 201123 can be an integral structure. That is, the main structure 201121, the first lug 201122 and the second lug 201123 can be manufactured using the same manufacturing process. For example, the main structure 201121, the first lug 201122 and the second lug 201123 are manufactured using the same mold.

[0113] refer to Figure 4 and Fig.13, the first side surface 201122a of the first lug 201122, the first side surface 201123a of the second lug 201123 and the first side surface 201121b of the main structure 201121 may be coplanar. Of course, the first side surface 201122a of the first lug 201122 may be coplanar with the first side surface 201123a of the second lug 201123, and the first side surface 201122a of the first lug 201122 and the first side surface 201123a of the second lug 201123 are not coplanar with the first side surface of the main structure 201121. In the embodiment of the present application, the first side surface 201121b of the main structure 201121 is parallel to the axial direction of the first through hole 201121a of the adjustment structure 2011.

[0114] After the curvature of the support device 201 changes, the distance between the axis of the first through hole 201121a of each adjustment structure 2011 and the axis of the first through hole 201121a of the adjacent adjustment structure 2011 will change. Figure 4 , Figure 5 , Figure 8 , Fig. 9 , Fig.12 as well as Fig.13 The first through hole 201121a provided in the main structure 201121 can be a strip-shaped through hole to facilitate adjusting the curvature of the supporting device 201.

[0115] The greater the curvature of the support device 201, the greater the bending degree of the support device 201, and the greater the distance between the axes of the first through holes 201121a in the adjacent adjustment structures 2011 in the support device 201. The smaller the curvature of the support device 201, the smaller the bending degree of the support device 201, and the smaller the distance between the axes of the first through holes 201121a in the adjacent adjustment structures 2011 in the support device 201.

[0116] Optionally, the curvature of the support device 201 can be as small as 0, that is, the line connecting the axes of the first through holes 201121a in the adjacent adjustment structures 2011 in the support device 201 is a straight line. In addition, when the curvature of the support device 201 is 0, the distance between the axes of the first through holes 201121a in the adjacent adjustment structures 2011 in the support device 201 is as small as possible.

[0117] In the examples of this application, refer to Fig.19The fixing member 20111 may be a second screw. The first through hole 201121a may have a first annular boss 201121a1, and the diameter of the head 201111 of the second screw 20111 may be larger than the inner diameter of the first boss 201121a1 and smaller than the inner diameter of the first through hole 201121a.

[0118] Furthermore, the head 201111 of the second screw 20111 near the side of the connecting portion 201112 of the second screw 20111 can contact the first surface c1 of the first boss 201121a1. After the rotating member 20112 is fixedly connected to the bendable structure 202 by the second screw 20111, the first surface c1 of the first boss 201121a1 is away from the back side of the bendable structure 202 relative to the second surface c2. The first surface c1 of the first boss 201121a1 can be parallel to the second surface c2.

[0119] In the examples of this application, refer to Fig.19 The distance m1 between the first surface c1 of the first boss 201121a1 and the first end surface d1 of the main structure 201121 may be equal to the distance m2 between the second surface c2 of the first boss 201121a1 and the second end surface d2 of the main structure 201121. The first end surface d1 of the main structure 201121 may be parallel to the second end surface d2 of the main structure 201121, and the second end surface d2 is a surface connected to the back side of the bendable structure 202.

[0120] Of course, the distance between the first surface c1 of the first boss 201121a1 and the first end surface d1 of the main structure 201121 may not be equal to the distance between the second surface c2 of the first boss 201121a1 and the second end surface d2 of the main structure 201121, and this embodiment of the present application does not limit this.

[0121] refer to Fig.19 The length of the connecting portion 201112 of the second screw 20111 may be smaller than the distance between the first surface c1 of the first boss 201121a1 and the second end surface d2 of the main structure 201121, so as to prevent the connecting portion 201112 of the second screw 20111 from abutting against the back side of the bendable structure 202 and causing damage to the bendable structure 202.

[0122] In addition, in order to ensure the reliability of the support device supporting the bendable structure, the distance between the end surface of the multiple adjustment structures 2011 in the support device 201 that is away from the back side of the bendable structure and the back side of the bendable structure is equal. For example, if the curvature of the support device 201 is 0, the first end surfaces d1 of the multiple adjustment structures 2011 in the support device 201 are coplanar, and the second end surfaces d2 of the multiple adjustment structures 2011 are coplanar.

[0123] In the embodiment of the present application, the roughness of the side where the head 201111 of the second screw 20111 and the first boss 201121a1 contact each other is greater than the roughness threshold, which can avoid relative movement between the second screw 20111 and the first boss 201121a1 after the second screw 20111 is used to fix the rotating part 20112 and the flexible structure 202, thereby ensuring the reliability of the supporting device 201.

[0124] Optionally, the roughness of the side of the head 201111 of the second screw 20111 close to the connecting portion 201112 of the second screw 20111 can be set to be larger, and the roughness of the first surface c1 of the first boss 201121a1 in contact with the head 201111 of the second screw 20111 can be set to be larger.

[0125] In summary, an embodiment of the present application provides a supporting device, which includes a plurality of adjustment structures connected in sequence, each adjustment structure is used to connect to the back side of a bendable structure, and any two adjacent adjustment structures among the plurality of adjustment structures can rotate relative to each other. Therefore, the curvature of the supporting device can be adjusted by adjusting the rotation angle between each adjustment structure and the adjacent adjustment structure, thereby adjusting the curvature of the bendable structure connected to the supporting device, and the use flexibility of the bendable structure is high.

[0126] Fig. 20 is a schematic diagram of the structure of a bendable device provided in an embodiment of the present application. Fig. 20 The bendable device 20 may include: a bendable structure 202 and at least one supporting device 201 as provided in the above embodiment. For example, Fig. 20 A supporting device 201 is shown in FIG.

[0127] The support device 201 can be disposed on the back side of the bendable structure 202 and connected to the back side of the bendable structure 202. Furthermore, since the curvature of the support device 201 can be adjusted, the curvature of the bendable structure 202 can also be adjusted, that is, the curvature of the bendable structure 202 is not a fixed curvature, and the bendable structure 202 has high flexibility in use.

[0128] Optionally, the bendable structure 202 may be a flexible display panel. Accordingly, the bendable device 20 may be a display device. Of course, the bendable structure 202 may also be other bendable structures, which is not limited in the present embodiment.

[0129] refer to Fig.21, the flexible display panel 202 may include a flexible display screen 2021 and a flexible backplane 2022. The flexible backplane 2022 may be located on the non-display side of the flexible display screen 2021, and the flexible backplane 2022 may be fixedly connected to the flexible display screen 2021. The support device 201 may be located on a side of the flexible backplane 2022 away from the flexible display screen 2021, and the support device 201 may be fixedly connected to the flexible backplane 2022. And, referring to Fig.21 The fixing member 20111 in the supporting device 201 may point to the center of the curved surface of the flexible display panel.

[0130] refer to Fig.19 and Fig. 22 The bendable device 20 may further include a plurality of annular second bosses 203 located on a side of the flexible back plate 2022 away from the flexible display screen 2021, and each second boss 203 may have a thread. The fixing member 20111 in the supporting device 20 may be threadedly connected to a second boss 203 to fix the rotating member 20112 in the supporting device 20 to the flexible back plate 2022.

[0131] In the examples of this application, refer to Fig.23 , the bendable device 20 may include: a plurality of supporting devices 201, for example, Fig.23 Two supporting devices 201 are shown. Since each of the multiple supporting devices 201 can support the bendable structure 202 and apply force to the bendable structure 201, the reliability of supporting the bendable structure 202 can be guaranteed, and the bending degree of each part of the bendable structure 201 can be made the same, thereby ensuring the quality of the bendable device 20.

[0132] The multiple adjustment structures 2011 in each support device 201 may be arranged along the target direction, so that the forces applied by the multiple support devices 201 to the bendable structure 202 are in the same direction, ensuring that the bendable structure 202 can bend in one direction.

[0133] For example, assuming that the bendable structure 202 is a flexible display panel, the target direction Z may be a row direction of pixels in the flexible display panel 202 .

[0134] Optionally, the display device can be electronic paper, an organic light-emitting diode (OLED) display device, an active-matrix organic light-emitting diode (AMOLED) display device, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame or a navigator, or any other product or component with a display function.

[0135] It should be noted that when the support device 201 provided in the embodiment of the present application is used to support the bendable structure 202, the user can first place the support device 201 (at this time, the connecting member 20113 is not completely tightened, and the adjacent adjustment structures 2011 can still rotate) on the back side of the bendable structure 202, and use the fixing member 20111 to pre-fix the rotating member 20112 (at this time, the fixing member 20111 is not completely tightened). Then, after the user adjusts the angle between each adjustment structure 2011, the connecting member 20113 is tightened to fix the curvature of the support device 201 (at this time, the curvature of the bendable structure 202 can be equal to the curvature of the support device 201). Finally, the fixing member 20111 is tightened to fix the rotating member 20112 to the bendable structure 202, thereby realizing the support of the bendable structure 202 by the support device 201, and fixing the curvature of the bendable structure 202.

[0136] In summary, an embodiment of the present application provides a bendable device, which includes a bendable structure and at least one supporting device, wherein the supporting device includes a plurality of adjustment structures connected in sequence, each adjustment structure is used to connect to the back side of the bendable structure, and any two adjacent adjustment structures among the plurality of adjustment structures can rotate relative to each other, so the curvature of the supporting device can be adjusted by adjusting the rotation angle between each adjustment structure and the adjacent adjustment structure, thereby adjusting the curvature of the bendable structure connected to the supporting device, and the use flexibility of the bendable structure is high.

[0137] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
