[0043] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] In the related art, the support plate is used as a support member of the flexible display module. The support plate is usually patterned to reduce the rigidity of the support plate, thereby improving the bending performance of the support plate. However, the bending limit radius cannot be controlled, resulting in the terminal mechanism extruding the module (such as Figure 1 As shown in the figure), the flexible module can only bear the extrusion force, which is very easy to produce dead folds (such as Figure 2 As shown), the screen fails; when the support plate is bent to the limit, the pattern position is twisted (as shown Figure 3As shown in the figure, and only when the flexible display module is bent to the extreme, the graphic design (pattern) can play a role of mutual restraint.

[0046] Based on the above reasons, the present application provides a support plate and a display device, which support plate includes at least one bending portion 100 and a flat portion 200 connected to the bending portion 100, the bending portion 100 includes a plurality of opening units, the plurality of opening units are arranged at intervals along a first direction (X direction), and the opening unit includes a plurality of openings 10 arranged along a second direction (Y direction), and the first direction (X direction) is perpendicular to the second direction (Y direction); at least one self-locking component 20 is arranged in each opening 10, and the self-locking component 20 includes two protrusions 21 arranged at intervals, and the two protrusions are respectively located on the two side walls of the opening 10 in the first direction (X direction), and the orthographic projections of the two protrusions 21 in the first direction (X direction) at least partially overlap. In this embodiment, by adding the self-locking component 20 in the opening 10, when the bending portion 100 of the support plate is bent, the two protrusions 21 in the opening 10 will form a hard contact, thereby improving the bending resistance of the support plate and reducing the risk of dead bending of the flexible display module.

[0047] Next, combine Figure 4-Figure 10 The support plate (Bracket, BKT) provided in the embodiment of the present application is described, and the support plate is applied to a flexible display device. The support plate is arranged on the backlight side of the flexible display panel to support the flexible display panel.

[0048] In this embodiment, the support plate includes at least one bending portion 100 and at least two flat portions 200 connected to the bending portion 100, wherein the number of the bending portions 100 and the flat portions 200 in the support plate mainly depends on whether the display device has a folding structure. For example, when the display device has a two-folding structure, the support plate includes two flat portions 200 and a bending portion 100 connecting the two flat portions 200. For example, when the display device has a three-folding structure, the support plate includes three flat portions 200 and two bending portions 100 respectively connecting adjacent flat portions 200.

[0049] It should be noted that the flat portion 200 and the bent portion 100 of the support plate in this embodiment are fixedly connected and may be an integrally formed structure, such as Figure 6 As shown, it can be understood that the flat portion 200 and the bent portion 100 are connected by ribs, wherein the ribs include first ribs 31 arranged between adjacent openings in the first direction (X direction) and second ribs 32 arranged between adjacent openings 10 in the second direction (Y direction); or as Fig. 9As shown, in this embodiment, at least one bent portion is connected to the flat portion by a hinge unit. The hinge unit includes a hinge located between adjacent openings, and multiple hinges are connected to each other. Each hinge includes a connecting plate 34 connecting adjacent openings 10 in a first direction (X direction) and a hinge axis connecting adjacent openings 10 in a second direction (Y direction); wherein the hinge axis 33 of each hinge, wherein the extension direction of the hinge axis of the hinge is parallel to the second direction (Y direction), and the opening in this application can be understood as the gap between multiple hinges.

[0050] For example, the material of the support plate can be metal, such as stainless steel (SUS), titanium alloy, etc.; the support layer plate can also be a composite fiber board, such as a carbon fiber composite board, but not limited thereto. The composite fiber board has the characteristics of high strength, high modulus, good heat dissipation effect, and light weight, which is conducive to the thinness and heat dissipation of the display module.

[0051] In one embodiment, the bending portion 100 of the support plate includes a plurality of opening units, and the plurality of opening units are spaced apart in a first direction (X direction). In this embodiment, since the support plate is generally made of metal or composite fiber board having greater rigidity, a plurality of opening units are provided on the bending portion 100, which can reduce the rigidity of the support plate in the bending area to improve the bending performance of the support plate. At the same time, in order to evenly disperse the stress of the bending portion 100 during bending and avoid stress concentration, adjacent opening units are generally staggered in the first direction (X direction), that is, adjacent opening units are not directly opposite one to another in the first direction (X direction).

[0052] In one embodiment, each opening unit includes a plurality of openings 10 arranged along a second direction (Y direction), wherein, in the first direction (X direction), a first rib 31 is arranged between adjacent openings 10, that is, in the first direction (X direction), adjacent openings 10 are connected by the first rib 31, and in the second direction (Y direction), a second rib 32 is arranged between adjacent openings 10, that is, in the second direction (Y direction), adjacent openings 10 are connected by the second rib 32, wherein the first rib 31 and the second rib 32 are integrally formed, and the first rib 31 and the second rib 32 are a whole.

[0053] It should be noted that, in the present embodiment, the direction in which the folding axis of the support plate extends is a first direction (X direction), and the direction perpendicular to the extension of the folding axis is a second direction (Y direction), wherein the first direction (X direction) and the second direction (Y direction) are coplanar and parallel to the surface of the support plate.

[0054] In one embodiment, the opening 10 penetrates the support plate in a direction perpendicular to the surface of the support plate. By providing a plurality of openings 10 penetrating the support plate on the bending portion 100, the rigidity of the bending portion 100 in the support plate can be reduced to improve the bending performance of the support plate. However, the first ribs 31 on both sides of the opening 10 or the connecting plate 34 of the hinge will deform (such as torsion bending) when the bending portion 100 is bent, thereby reducing the rigidity of the first ribs 31 on both sides of the opening 10 or the connecting plate 34 of the hinge. Under the action of external force, the display module is prone to deadlock. Therefore, in order to reduce the probability of the display module being bent to death under the action of external force, the stiffness of the first ribs 31 on both sides of the opening 10 or the connecting plates 34 of the hinges is increased to avoid the first ribs 31 on both sides of the opening 10 or the connecting plates 3 of the hinges from twisting and bending. Therefore, in the present application, at least one self-locking component 20 is arranged in the opening 10. The self-locking component 20 is mainly used to avoid the first ribs 31 or the connecting plates 34 of the hinges from transitional twisting and bending when the bending portion 100 of the support plate is bent, thereby improving the anti-bending ability of the support plate and reducing the risk of the module being bent to death.

[0055] Specifically, the self-locking component 20 includes two protrusions 21 arranged at intervals, and the two protrusions 21 are respectively located on the two side walls of the opening 10 in the first direction (X direction), and the orthographic projections of the two protrusions 21 in the first direction (X direction) at least partially overlap. This design makes it possible for the two protrusions 21 to form a hard contact when the bending portion 100 of the support plate is bent, thereby avoiding transitional torsional bending of the first rib 31 or the connecting plate 34 of the hinge, thereby improving the anti-bending ability of the support plate and reducing the risk of dead bending of the display module, such as Fig.10 As shown, the rebound force of the support plate BKT when bent is compared before and after the self-locking structure is added. When the self-locking structure (two protrusions) are in contact, the rebound force of the support plate BKT is increased by about 80%, greatly reducing the risk of module dead bend.

[0056] Furthermore, the protrusion 21 is mainly located on the side wall surface of the first rib 31 or the connecting plate 34 of the hinge facing the opening 10, and the protrusion 21 extends to one side of the opening 10. This design reduces the gap between the opening 10 and the protrusion 21, so that when the bending portion 100 of the support plate is bent, hard contact can be achieved between the two protrusions 21, thereby improving the bending resistance of the support plate and reducing the risk of dead bending of the display module. Specifically, in this embodiment, the protrusion 21 and the first rib 31 are integrally formed or the protrusion 21 and the connecting plate 34 of the hinge are integrally formed. In the direction perpendicular to the surface of the support plate, the size of the protrusion 21 is equal to the size of the first rib 31 or the connecting plate 34 of the hinge. In this embodiment, the size of the protrusion 21 in the first direction (X direction) can be specifically understood as the height of the protrusion 21 in the first direction (X direction), and the size of the first rib 31 or the connecting plate 34 of the hinge in the first direction (X direction) can be specifically understood as the height of the first rib 31 or the connecting plate 34 of the hinge in the first direction (X direction).

[0057] refer to Figure 6-Figure 9 In one embodiment, the orthographic projections of the two protrusions 21 in the self-locking assembly 20 in the first direction (X direction) must at least partially overlap, so as to ensure that when the bending portion 100 of the support plate is in the bent state, the two protrusions 21 can form a hard contact. In one embodiment, the two protrusions 21 of each opening 10 are staggered in the first direction (X direction) (such as Figure 8 As shown), that is, the orthographic projections of the two protrusions 21 in the first direction (X direction) overlap, and at this time, the size D3 of the overlapping portion is smaller than the size of each protrusion 21. However, the present application has certain requirements for the area of ​​the corresponding overlapping portion of the two protrusions 21. If the two hard contact areas are too large, it may affect the bending performance of the bending portion 100 of the support plate, so that the bending performance of the bending portion 100 in the support plate cannot meet the bending requirements. If the two hard contact areas are too small, the self-locking component 20 cannot play a role, and the hard contact between the two protrusions 21 cannot be effectively exerted to avoid the first ribs 31 on both sides of the opening 10 or the connecting plate 34 of the hinge from twisting. In this embodiment, the two protrusions 21 are staggered, which increases the size of each protrusion 21 in the second direction (Y direction) to a certain extent. Such a design may affect the bending performance of the bending portion 100 in the support plate, so as a preferred embodiment (such as Figure 6 and Figure 7 As shown in FIG. 1 , the two protrusions 21 in each opening 10 are symmetrically arranged about the axis of the corresponding opening 10 in the second direction (Y direction), that is, the positive projections of the two protrusions 21 in the first direction (X direction) completely overlap, that is, the size of the overlapping part is the size of each protrusion 21.

[0058] refer to Figure 6-Figure 9 In one embodiment, the plurality of openings 10 include a plurality of first openings 11 arranged in a row along a second direction (Y direction) and a second opening 12 located at at least one end of the row and spaced apart from the first openings 11, wherein the first opening 11 is a closed opening 10, the second opening 12 is a non-closed opening 10, and the side wall of the second opening 12 constitutes a partial side surface of the bending portion 100, the first opening 11 penetrates the bending portion 100 in a direction perpendicular to the surface where the support plate is located, and the second opening 12 penetrates the bending portion 100 in a direction perpendicular to the surface where the support plate is located.

[0059] Further, in the first direction (X direction), the size of the first opening 11 is equal to the size of the second opening 12, where the sizes of the second opening 12 and the second opening 12 specifically refer to the widths of the first opening 11 and the second opening 12; in the second direction (Y direction), the size of the second opening 12 is smaller than the size of the first opening 11 and greater than or equal to half the size of the first opening 11, where the sizes of the first opening 11 and the second opening 12 specifically refer to the lengths of the first opening 11 and the second opening 12. This design ensures that there is at least one self-locking component 20 in the second opening 12.

[0060] refer to Figure 6 and Fig. 9 In one embodiment, a self-locking component 20 is provided in each opening 10, and the orthographic projection of the second rib 32 or the hinge shaft 33 in the first direction (X direction) is located within the orthographic projection range of the self-locking component 20 in the first direction (X direction). Further, the orthographic projections of the two protrusions 21 of the self-locking component 20 in the first direction have an overlapping portion, and the orthographic projection of the second rib 32 or the hinge shaft 33 in the first direction (X direction) is located within the orthographic projection range of the overlapping portion in the first direction. In this embodiment, only one self-locking component is provided in each of the first opening 11 and the second opening 12 20. When the bending portion 100 of the support plate is bent, each opening 10 corresponding to the second rib 32 or the hinge shaft 33 is prone to twisting at the end position in the second direction (Y direction). Therefore, in this embodiment, the self-locking component 20 is set at the end position of the opening 10 corresponding to the second rib 32 or the hinge shaft 33 in the second direction (Y direction). This can enhance the shape retention ability of this position in the bent state, effectively control the distortion of the first ribs 31 on both sides of the opening 10 or the connecting plates 34 of the hinge when the support plate is bent, and increase the ability of the first ribs 31 or the connecting plates 34 of the hinge to resist deformation.

[0061] refer to Figure 7In another embodiment, considering that setting a self-locking component 20 at the end position of the second rib 32 in the second direction (Y direction) corresponding to the opening 10 will make the stiffness at this position too large, thereby affecting the performance of the bending portion 100 in the support plate, two self-locking components 20 are set in the first opening 11, and the two self-locking components 20 are arranged at intervals along the second direction (Y direction), and one self-locking component 20 is set in the second opening 12. Furthermore, the two self-locking components 20 in the first opening 11 are distributed on both sides of the second rib 32 or the hinge shaft 33, that is, the self-locking components 20 are arranged at multiple points in the opening 10 in this embodiment, which further enhances the ability to resist deformation and improves the stiffness of the bending portion 100 in the support plate when bending.

[0062] Of course, the number of self-locking components in the present application can also be 3, 4 or more, but it should be noted that as the number increases, the corresponding size of the protrusion needs to be reduced to a certain extent to avoid the protrusion affecting the bending property of the bending part in the support plate.

[0063] refer to Figure 6 In one embodiment, in the first direction (X direction), the size of the protrusion 21 is smaller than half the size of the opening 10. In this embodiment, the size of the protrusion 21 in the first direction (X direction) can be specifically understood as the width of the protrusion 21 in the first direction (X direction), that is, in the first direction (X direction), the width L1 of the protrusion 21 is smaller than half the width L2 of the opening 10. Only in this way can a gap be provided between the two protrusions 21 in each opening 10, thereby avoiding affecting the bending of the bending portion 100 in the support plate.

[0064] refer to Figure 6 and Figure 8 In one embodiment, in the second direction (Y direction), the size of the protrusion 21 is greater than or equal to the size of the second rib 32 or the hinge shaft 33. In this embodiment, the size of the protrusion 21 in the second direction (Y direction) can be specifically understood as the length of the protrusion 21 in the second direction (Y direction), that is, in the second direction (Y direction), the length D2 of the protrusion 21 is greater than or equal to the length D1 of the second rib 32. Furthermore, the orthographic projections of the two protrusions in the first direction have an overlapping portion. In the second direction (Y direction), the size D3 of the overlapping portion is greater than or equal to the size D1 of the second rib. On the one hand, such a design can achieve effective hard contact between the two protrusions 21 to avoid torsional bending of the first rib 31 when bending. On the other hand, this can further reduce the probability of torsion at the end position of each opening 10 corresponding to the second rib 32 in the second direction (Y direction), thereby improving the anti-bending ability of the support plate and reducing the risk of dead bending of the module.

[0065] In one embodiment, the orthographic projection of the protrusion 21 in a direction perpendicular to the surface where the support plate is located is rectangular or trapezoidal.
