Compared to traditional screens, flexible screens offer advantages such as thinness, lightness, and low power consumption. Furthermore, due to their bendability and flexibility, their application scenarios are becoming increasingly widespread.

[0043] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] In related technologies, the support plate, as a supporting component of the flexible display module, is typically designed with a graphical pattern to reduce its stiffness and improve its bending performance. However, the bending radius cannot be controlled, leading to problems when the terminal components compress the module (e.g., ...). Figure 1 As shown), it can only withstand the compressive force through flexible modules, which makes it extremely prone to dead bends (such as...). Figure 2 As shown), this causes the screen to fail; when the support plate is bent to its limit, the patterned design position twists (as shown). Figure 3As shown in the figure, the graphical design (pattern) can only play a mutually restrictive role when the flexible display module is bent to its limit.

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

[0047] Next, let's combine Figures 4-10 This application describes a support plate (Bracket, BKT) provided in an embodiment, which is applied to a flexible display device. The support plate is disposed on the backlight side of the flexible display panel to provide support for the flexible display panel.

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

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

[0050] For example, the material of the support plate can be metal, such as stainless steel (SUS), titanium alloy, etc.; the support layer can also be a composite fiberboard, such as carbon fiber composite board, but is not limited to these. Composite fiberboard has the characteristics of high strength, high modulus, good heat dissipation, and light weight, which is beneficial to the thinning and lightening of display modules and heat dissipation.

[0051] In one embodiment, the bending portion 100 of the support plate includes a plurality of opening units, which are spaced apart in a first direction (X direction). In this embodiment, since the support plate is usually made of metal or composite fiberboard with high rigidity, providing a plurality of opening units on the bending portion 100 can reduce the rigidity of the support plate in the bending area and improve the bending performance of the support plate. At the same time, in order to evenly distribute the stress of the bending portion 100 during bending and avoid stress concentration, adjacent opening units are usually staggered in the first direction (X direction), that is, adjacent opening units are not directly opposite each other 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). In the first direction (X direction), a first rib 31 is provided between adjacent openings 10, that is, adjacent openings 10 are connected by the first rib 31 in the first direction (X direction). In the second direction (Y direction), a second rib 32 is provided between adjacent openings 10, that is, adjacent openings 10 are connected by the second rib 32 in the second direction (Y direction). The first rib 31 and the second rib 32 are integrally formed and are a whole.

[0053] It should be noted that in this embodiment, the direction in which the folding axis of the support plate extends is the first direction (X direction), and the direction perpendicular to the folding axis is the second direction (Y direction). The first direction (X direction) and the second direction (Y direction) are coplanar and are both 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 plane of the support plate. By providing multiple openings 10 penetrating the support plate on the bending portion 100, the stiffness 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 torsional bending) when the bending portion 100 is bent, thereby reducing the stiffness 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 deadening. To reduce the probability of the display module breaking under external force, the rigidity of the first ribs 31 or the connecting plate 34 of the hinge on both sides of the opening 10 is increased to prevent the first ribs 31 or the connecting plate 34 of the hinge on both sides of the opening 10 from twisting and bending. Therefore, at least one self-locking component 20 is provided in the opening 10. The self-locking component 20 is mainly used to prevent the first ribs 31 or the connecting plate 34 of the hinge from excessively twisting and bending when the bending part 100 of the support plate is bent, thereby improving the bending resistance of the support plate and reducing the risk of the module breaking.

[0055] Specifically, the self-locking assembly 20 includes two spaced-apart protrusions 21, which are located on opposite sides of the opening 10 in the first direction (X direction). The orthographic projections of the two protrusions 21 in the first direction (X direction) at least partially overlap. This design ensures that when the bending portion 100 of the support plate is bent, the two protrusions 21 form a hard contact, preventing excessive torsional bending of the first rib 31 or the hinge connecting plate 34. This improves the bending resistance of the support plate and reduces the risk of fatal bending of the display module. Figure 10 As shown, the comparison of the rebound force of the support plate BKT when bending before and after adding the self-locking structure shows that when the self-locking structure (two protrusions) comes into contact, the rebound force of the support plate BKT increases by about 80%, which greatly reduces the risk of module failure.

[0056] Furthermore, the protrusion 21 is mainly located on the side wall of the first rib 31 or the connecting plate 34 of the hinge facing the opening 10, and the protrusion 21 extends towards 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, the two protrusions 21 can make hard contact, 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 is integrally formed with the first rib 31 or the protrusion 21 is integrally formed with the connecting plate 34 of the hinge. 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 Figures 6-9 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 to ensure that a hard contact can be formed between the two protrusions 21 when the bent portion 100 of the support plate is in the bent state. In one embodiment, the two protrusions 21 of each opening 10 are staggered in the first direction (X direction) (e.g., Figure 8 As shown), the two protrusions 21 overlap in the orthographic projection of the first direction (X direction). The size D3 of this overlap is smaller than the size of each protrusion 21. However, this application has certain requirements for the area of ​​the overlapping portion of the two protrusions 21. If the area of ​​the two hard contacts is too large, it may affect the bending performance of the bending portion 100 of the support plate, causing it to fail to meet the bending requirements. If the area of ​​the two hard contacts is too small, the self-locking component 20 cannot function effectively, and the hard contact between the two protrusions 21 cannot effectively prevent 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 to some extent increases the size of each protrusion 21 in the second direction (Y direction). This design may affect the bending performance of the bending portion 100 in the support plate. Therefore, as a preferred embodiment (e.g....), Figure 6 and Figure 7 As shown), two protrusions 21 within each opening 10 are symmetrically arranged about the axis of the corresponding opening 10 in the second direction (Y direction), that is, the orthographic projections of the two protrusions 21 in the first direction (X direction) completely overlap, and the size of the overlapping part is the size of each protrusion 21.

[0058] refer to Figures 6-9 In one embodiment, the plurality of openings 10 include a plurality of first openings 11 arranged in a column along a second direction (Y direction) and second openings 12 located at at least one end of the column and spaced apart from the first openings 11, wherein the first openings 11 are closed openings 10, the second openings 12 are open openings 10, and the sidewalls of the second openings 12 form part of the sidewalls of the bend 100. The first openings 11 penetrate the bend 100 in a direction perpendicular to the surface of the support plate, and the second openings 12 penetrate the bend 100 in a direction perpendicular to the surface of the support plate.

[0059] Furthermore, 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 size of the second opening 12 specifically refers to the width 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 size of the first opening 11 and the second opening 12 specifically refers to the length of the first opening 11 and the second opening 12. This design ensures that at least one self-locking component 20 will exist in the second opening 12.

[0060] refer to Figure 6 and Figure 9 In one embodiment, a self-locking assembly 20 is provided in each opening 10, and the orthographic projection of the second rib 32 or hinge pin 33 in the first direction (X direction) is located within the orthographic projection range of the self-locking assembly 20 in the first direction (X direction). Further, the orthographic projections of the two protrusions 21 of the self-locking assembly 20 in the first direction overlap, and the orthographic projection of the second rib 32 or hinge pin 33 in the first direction (X direction) is located within the range of the orthographic projection of the overlapping portion in the first direction. In this embodiment, only one self-locking assembly is provided in each of the first opening 11 and the second opening 12. 20. When the support plate is bent at the bending part 100, each opening 10 is prone to twisting at the end position of the second rib 32 or hinge pin 33 in the second direction (Y direction). Therefore, in this embodiment, the self-locking component 20 is set at the end position of the second rib 32 or hinge pin 33 in the second direction (Y direction) corresponding to the opening 10. This can enhance the shape retention ability of this position in the bending state, effectively control the twisting of the first rib 31 or the connecting plate 34 of the hinge on both sides of the opening 10 when the support plate is bent, and increase the ability of the first rib 31 or the connecting plate 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) of the opening 10 would make the stiffness at that position too large, thereby affecting the performance of the bent 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). 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, in this embodiment, the self-locking components 20 are arranged at multiple points in the opening 10, which further improves the ability to resist deformation and improves the stiffness of the bent portion 100 in the support plate when bending.

[0062] Of course, the number of self-locking components in this application can also be 3, 4 or more, but it should be noted that as the number increases, the size of the protrusion needs to be reduced to a certain extent to avoid the protrusion affecting the bending 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 less 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 less than half the width L2 of the opening 10. This design ensures that there is a gap 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 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. This design can, on the one hand, achieve effective hard contact between the two protrusions 21, avoiding torsional bending of the first rib 31 when bending. On the other hand, it can further reduce the probability of torsion at the end position of the second rib 32 corresponding to each opening 10 in the second direction (Y direction), improve the bending resistance of the support plate, and reduce the risk of dead bending of the module.

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

[0066] Based on the same inventive concept, this disclosure also provides a display device, which includes the display module provided in the embodiments of this disclosure. Since the principle of the display device in solving the problem is similar to that of the support plate in solving the problem, the implementation of the display device provided in the embodiments of this disclosure can refer to the implementation of the display module provided in the embodiments of this disclosure, and the repeated parts will not be described again.

[0067] The display device provided in this embodiment of the invention can be applied to mobile phones or any electronic product with display function, including but not limited to the following categories: televisions, laptops, desktop monitors, tablets, digital cameras, smart bracelets, smart glasses, in-vehicle displays, medical devices, industrial control equipment, touch interactive terminals, etc. This embodiment of the invention does not impose any special limitations on these.
