Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a support component and a display device. Background Technology

[0002] Flexible screens, also known as bendable displays, are increasingly being used in various electronic devices as the technology matures, enabling greater diversification of electronic equipment. To ensure the flatness and rigidity of the flexible screen, a support structure is typically placed on the side of the flexible screen facing away from the display surface. This support structure is attached to the flexible screen; however, existing support structures often do not perfectly match the bending deformation of the flexible screen. Summary of the Invention

[0003] This application provides a support component and a display device that can improve printing problems.

[0004] In a first aspect, embodiments of this application provide a support component for supporting a flexible screen. The flexible screen includes a first flat region, a second flat region, and a bending region located between the first flat region and the second flat region. The support component includes a first support member and a second support member. The first support member includes a first flat portion and a first curved portion connected to one end of the first flat portion along a first direction. The first flat portion is correspondingly disposed to the first flat region. The side of the first curved portion away from the first flat portion includes a groove structure. The first direction is parallel to the plane where the first flat portion is located.

[0005] The second support member includes a second straight portion and a second curved portion connected to one end of the second straight portion along a first direction. The second straight portion is correspondingly disposed to the second straight area. The side of the second curved portion away from the second straight portion includes a protruding structure. The protruding structure is at least partially located in the groove structure and is slidably disposed relative to the groove structure. A portion of the structure in the second curved portion is located on the side of the protruding structure facing the flexible screen, and when the support assembly is in a flattened state, the projection of the second curved portion in the thickness direction of the support assembly at least partially overlaps with the projection of the protruding structure in the thickness direction.

[0006] Secondly, embodiments of this application provide a display device, which includes a flexible screen and a support component as described in any of the foregoing embodiments. The flexible screen includes a first flat region, a second flat region, and a bending region located between the first flat region and the second flat region. The first flat portion of the support component corresponds to the first flat region, and the second flat portion of the support component corresponds to the second flat region.

[0007] This application provides a support component and a display device. The support component includes a first support member and a second support member. The side of the first support member is etched to form a groove structure, and the side of the second support member is designed to protrude to form a raised structure. The sliding fit between the groove structure and the raised structure satisfies the stress release requirements of the support component during bending deformation. With this design, there is no need to etch the surfaces of the first and second support members that are attached to the flexible screen. As a result, the surfaces of the first and second support members that are attached to the flexible screen are both integral structures. This allows more areas of the flexible screen to be attached to the support component in the bending area, thereby improving the support effect of the support component on the flexible screen in the bending area and improving molding and crease problems.

Detailed Implementation

[0011] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0012] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0013] Firstly, please refer to Figures 2 to 6 This application provides a support component 100 for supporting a flexible screen 200. The flexible screen 200 includes a first flat area A1, a second flat area A2, and a bending area A3 located between the first flat area A1 and the second flat area A2. The support component 100 includes a first support member 10 and a second support member 20. The first support member 10 includes a first flat portion 11 and a first curved portion 12 connected to one end of the first flat portion 11 along a first direction X. The first flat portion 11 is correspondingly disposed to the first flat area A1. The side of the first curved portion 12 facing away from the first flat portion 11 includes a groove structure 13. The first direction X is parallel to the plane where the first flat portion is located.

[0014] The second support member 20 includes a second straight portion 21 and a second curved portion 22 connected to one end of the second straight portion 21 along the first direction X. The second straight portion 21 is correspondingly disposed to the second straight region A2. The side of the second curved portion 22 away from the second straight portion 21 includes a protruding structure 23. The protruding structure 23 is at least partially located in the groove structure 13 and is slidably disposed relative to the groove structure 13. A portion of the structure in the second curved portion 22 is located on the side of the protruding structure 23 facing the flexible screen 200. When the support assembly 100 is in a flattened state, the projection of the second curved portion 22 in the thickness direction Z of the support assembly 100 at least partially overlaps with the projection of the protruding structure 23 in the thickness direction Z.

[0015] The support component 100 works in conjunction with the flexible screen 200 to form the display device 300. Specifically, the flexible screen 200 is referred to as a bendable display screen. With the gradual maturation of flexible screen 200 technology, it has been widely used in various fields to achieve diversified displays. During use, the flexible screen 200 can be bent or flattened. For example, when a user needs to carry the display device 300, they can fold it in half and put it in a bag or pocket; when a user needs to view the display device 300, they can unfold it.

[0016] However, when the flexible screen 200 is bent or flattened, the opposite sides of the flexible screen 200 will be continuously subjected to inward compressive force and outward tensile force. Under long-term use, this can easily lead to insufficient flatness and rigidity of the flexible screen 200. Among them, rigidity is called elastic modulus, which refers to the ability of a material or structure to resist elastic deformation when subjected to force. Generally speaking, the larger the elastic modulus or rigidity, the smaller the elastic deformation, and the smaller the elastic modulus or rigidity, the larger the elastic deformation.

[0017] Therefore, to ensure the flatness and rigidity of the flexible screen 200 when bent or unfolded, the display device 300 typically also includes a support component 100. The support component 100 is attached to the back of the flexible screen 200 to support it. The support component 100 needs to have a certain degree of elasticity so that when used in conjunction with the flexible screen 200, it can bend and deform together with the flexible screen 200 while ensuring its flatness and rigidity.

[0018] Next, the structure of the flexible screen 200 and the supporting component 100 will be described in detail. The flexible screen 200 includes a first flat area A1, a second flat area A2, and a bending area A3 located between the first flat area A1 and the second flat area A2. During the bending or flattening of the flexible screen 200, the first flat area A1 and the second flat area A2 will not bend or deform, while the bending area A3 will deform relatively. Specifically, when the flexible screen 200 is flat, the first flat area A1, the second flat area A2, and the bending area A3 are all flat, and all three are relatively exposed to increase the display panel size. When the flexible screen 200 is bent, the first flat area A1 and the second flat area A2 are flat, while the bending area A3 is bent. The second flat portion 21 is hidden behind the first flat area A1 through the bending area A3. At this time, only a portion of the structure in the first flat area A1 and the bending area A3 is exposed, thus facilitating transfer and carrying.

[0019] For support component 100, support components in related technologies often adopt the following... Figure 1 The structure shown, where the surface of the support component facing the flexible screen is not a single, continuous structure matching the flexible screen, is instead formed with multiple hollow sections 40 through etching and other processes. At least some of these hollow sections 40 correspond to the bending areas in the flexible screen. In this way, the support component can release stress in the corresponding areas of the bending areas using the hollow sections 40, meeting the requirement of bending and deforming together with the flexible screen. However, this design reduces the contact area between the flexible screen and the support component in the bending areas, resulting in a decrease in the support effect of the support component on the flexible screen in the bending areas, and consequently, mold marks and creases appearing in the bending areas.

[0020] In view of this, the structure of the support component 100 has been adjusted in this application embodiment. The support component 100 includes a first support member 10 and a second support member 20. The first straight portion 11 in the first support member 10 is used to support the first straight area A1 of the flexible screen 200, and the second straight portion 21 in the second support member 20 is used to support the second straight area A2 of the flexible screen 200. Furthermore, regardless of whether the support component 100 is in a flattened state or a bent state, the first straight portion 11 in the first support member 10 and the second straight portion 21 in the second support member 20 are both in a straight shape.

[0021] The first curved portion 12 is a part of the first support member 10 used to support the bending area A3, and the second curved portion 22 is a part of the second support member 20 used to support the bending area A3. The first curved portion 12 and the second curved portion 22 cooperate with each other to take into account both support and bending deformation requirements. Specifically, the first curved portion 12 has a groove structure 13, the opening of which faces the second support member 20. The second curved portion 22 has a protruding structure 23, which extends protruding towards the first support member 10. The protruding structure 23 is at least partially located within the groove structure 13, and the protruding structure 23 is not connected to the bottom wall of the groove structure 13 to meet the sliding requirement of the protruding structure 23 relative to the groove structure 13.

[0022] During the transition of the support assembly 100 from a flattened state to a bent state, the first bent portion 12 and the second bent portion 22 not only undergo individual bending deformation, but also slide relative to each other. The distance between the protruding structure 23 and the bottom wall of the groove structure 13 gradually increases. Thus, by means of the bending deformation of the two bent portions themselves and the relative sliding between them, the bending deformation requirements of the part of the support assembly 100 corresponding to the bending area A3 can be met. Similarly, during the transition of the support assembly 100 from a bent state to a flattened state, the first bent portion 12 and the second bent portion 22 gradually return to a straight shape, and also slide relative to each other. The distance between the protruding structure 23 and the bottom wall of the groove structure 13 gradually decreases.

[0023] Furthermore, the relative sliding between the protruding structure 23 and the groove structure 13 can meet the stress release requirements of the support component 100 during bending deformation. A portion of the structure in the first bent portion 12 is located on the side of the protruding structure 23 facing the flexible screen 200. That is, the structure within the groove structure 13 of the protruding structure 23 is hidden within the first bent portion 12 and will not be exposed relative to the surface of the first bent portion 12 facing the flexible screen 200 and will not adhere to the flexible screen 200. In other words, this embodiment achieves stress release within the support component 100 through relative sliding between different structures. Based on this, there is no need to etch the surface of the support component 100 that adheres to the flexible screen 200. This allows more areas of the flexible screen 200 within the bending region A3 to adhere to the support component 100, thereby improving the support effect of the support component 100 on the flexible screen 200 at the bending region A3.

[0024] It should be noted that, depending on the actual needs, the recessed size of the groove structure 13 and the protruding size of the protruding structure 23 can be the same or different. When the support assembly 100 is in a flattened state, the protruding structure 23 can be in contact with the bottom wall of the groove structure 13, or the protruding structure 23 can be spaced apart from the bottom wall of the groove structure 13. Furthermore, the first curved portion 12 can have only one groove structure 13, or the first curved portion 12 can have multiple groove structures 13 simultaneously. This application embodiment does not impose any limitations on this.

[0025] As for the second curved portion 22, the second curved portion 22 may only include the protruding structure 23, or the second curved portion 22 may also include other structures. Specifically, since the second curved portion 22 is a part of the second support member 20 used to support the bending area A3, if the end of the protruding structure 23 facing the second straight portion 21 is aligned with the boundary of the bending area A3, then the second curved portion 22 only includes the protruding structure 23, which is directly connected to the second straight portion 21. However, if the end of the protruding structure 23 facing the second straight portion 21 is not aligned with the boundary of the bending area A3, then the second curved portion 22 also includes other structures between the protruding structure 23 and the second straight portion 21.

[0026] Furthermore, the first support member 10 and the second support member 20 can be two completely independent components, meaning they are not connected in any region along the thickness direction Z. Alternatively, the first support member 10 and the second support member 20 can be connected in a portion of the thickness direction Z, but not connected in the remaining regions, thus satisfying the sliding requirement of the protruding structure 23 relative to the groove structure 13.

[0027] In summary, in this embodiment, the support component 100 includes a first support member 10 and a second support member 20. The side of the first support member 10 is etched to form a groove structure 13, and the side of the second support member 20 is designed to form a protruding structure 23. The sliding fit between the groove structure 13 and the protruding structure 23 satisfies the stress release requirement of the support component 100 during bending deformation. Under this design, there is no need to etch the surfaces of the first support member 10 and the second support member 20 that are attached to the flexible screen 200. As a result, the surfaces of the first support member 10 and the second support member 20 that are attached to the flexible screen 200 are both integral structures. This allows more areas of the flexible screen 200 within the bending area A3 to be attached to the support component 100, thereby improving the support effect of the support component 100 on the flexible screen 200 at the bending area A3 and improving the molding and crease problems.

[0028] In some embodiments, please refer to Figures 7 to 11The first support member 10 includes a first support surface M1, which includes a first sub-surface M11 located within the first curved portion 12. The second support member 20 includes a second support surface M2, which includes a second sub-surface M21 located within the second curved portion 22. In the flattened state, the protruding structure 23 and the second sub-surface M21 are spaced apart in the thickness direction Z. The first sub-surface M11 and the second sub-surface M21 abut against each other and are coplanar to form a curved support surface, which covers the bending area A3. Figure 7 In the diagram, the curved support surface is indicated by thickened straight lines.

[0029] The first support surface M1 is the surface of the first support member 10 that is in contact with the flexible screen 200. The first sub-surface M11 is located within the first support surface M1 and is correspondingly arranged with the bending area A3. The first sub-surface M11 and the groove structure 13 have various dimensional relationships. For example, when the support assembly 100 is in a flattened state, the dimension of the first sub-surface M11 in the first direction X can be equal to the dimension of the groove structure 13 in the first direction X, or the dimension of the first sub-surface M11 in the first direction X can be greater than the dimension of the groove structure 13 in the first direction X.

[0030] The second support surface M2 is the surface on the second support member 20 that is in contact with the flexible screen 200. The second sub-surface M21 is located inside the second support surface M2 and is correspondingly arranged with the bending area A3. Since the protrusion structure 23 is not used to fit and support the flexible screen 200, when the support assembly 100 is in a flattened state, the protrusion structure 23 and the second sub-surface M21 are spaced apart in the thickness direction Z, and the projection of the second sub-surface M21 in the thickness direction Z is located on one side of the projection of the protrusion structure 23 in the thickness direction Z along the first direction X.

[0031] In this embodiment, by adjusting the dimensional relationship between the groove structure 13 and the protrusion structure 23, the protrusion size of the protrusion structure 23 is set to be no greater than the recess size of the groove structure 13. Thus, when the support component 100 is in a flattened state, the protrusion structure 23 can be completely located within the groove structure 13. Based on this, the first sub-surface M11 and the second sub-surface M21 can abut, that is, there is no gap between the first support surface M1 and the second support surface M2. In this way, the curved support surface formed by the coplanar first sub-surface M11 and the second sub-surface M21 can completely cover the bending area A3, so that the flexible screen 200 is completely fitted with the support component 100 at the bending area A3, thereby further enhancing the support effect of the support component 100 on the flexible screen 200 and improving the problems of molding and creases.

[0032] It should be noted that when the support component 100 is in a bent state, due to the relative sliding between the protruding structure 23 and the groove structure 13, there will be a certain gap between the first sub-surface M11 and the second sub-surface M21. However, the size of this gap is usually small. Therefore, most of the structure of the flexible screen 200 in the bending area A3 can fit with the support component 100, which can meet the support requirements of the flexible screen 200.

[0033] In some embodiments, such as Figures 8 to 11 As shown, the first curved portion 12 includes a first sub-portion 121 connected to the first straight portion 11, and a second sub-portion 122 connected to the side of the first sub-portion 121 away from the first straight portion 11. In the flattened state, the groove structure 13 is disposed through the second sub-portion 122 along the first direction X. The second curved portion 22 includes a third sub-portion 221 connected to the second straight portion 21, and a protruding structure 23 connected to the side of the third sub-portion 221 away from the second straight portion 21. During the transition from the flattened state to the curved state, the unit deformation of the second sub-portion 122 is greater than that of the first sub-portion 121, and the unit deformation of the protruding structure 23 is greater than that of the third sub-portion 221.

[0034] The first curved portion 12 includes a first sub-portion 121 and a second sub-portion 122. The second sub-portion 122 has a groove structure 13. In the flattened state, the projection of the groove structure 13 in the thickness direction Z is located on one side of the projection of the first sub-portion 121 in the thickness direction Z along the first direction X. The first sub-surface M11 includes the surface of the first sub-portion 121 facing the flexible screen 200 and the surface of the second sub-portion 122 facing the flexible screen 200.

[0035] The second curved portion 22 includes a third sub-portion 221 and a protruding structure 23. The protruding structure 23 protrudes from the side of the third sub-portion 221 facing the first support member 10. The surface of the third sub-portion 221 facing the flexible screen 200 is the second sub-surface M21.

[0036] It should be noted that, in the flattened state, the dimension of the first sub-part 121 in the first direction X can be greater than, less than or equal to the dimension of the second sub-part 122 in the first direction X. Similarly, the dimension of the third sub-part 221 in the first direction X can be greater than, less than or equal to the dimension of the protruding structure 23 in the first direction X. This application embodiment does not impose any restrictions on this.

[0037] Unit deformation is a physical quantity describing the degree of local deformation of an object. It can be quantified by the deformation per unit length. The unit deformation of the second sub-part 122 is greater than that of the first sub-part 121, indicating that the second sub-part 122 has a greater degree of deformation relative to the first sub-part 121 during the state transition of the support assembly 100. Similarly, the unit deformation of the protruding structure 23 is greater than that of the third sub-part 221, indicating that the protruding structure 23 has a greater degree of deformation relative to the third sub-part 221 during the state transition of the support assembly 100. Furthermore, considering that the support assembly 100 often has a large amount of deformation at the center region corresponding to the bending area A3, the protruding structure 23 and the groove structure 13 can be arranged corresponding to the center region of the bending area A3.

[0038] In this embodiment, a protrusion structure 23 and a groove structure 13 are provided in the area of ​​the support component 100 where the deformation is large. By means of the relative sliding between the protrusion structure 23 and the groove structure 13, more stress caused by the bending deformation of the support component 100 is released. While taking into account the support effect of the support component 100 on the flexible screen 200, the bending performance of the support component 100 is improved.

[0039] It should be noted that in some embodiments, the first curved portion 12 may only have a second sub-portion 122, without including the first sub-portion 121. In this case, the second sub-portion 122 is directly connected to the first straight portion 11. Similarly, in some embodiments, the second curved portion 22 may only have a protruding structure 23, without including the third sub-portion 221. In this case, the protruding structure 23 is directly connected to the second straight portion 21.

[0040] In some embodiments, such as Figures 8 to 11 As shown, the first curved portion 12 includes a second sub-portion 122. In the flattened state, the groove structure 13 extends through the second sub-portion 122 along the first direction X. The second sub-portion 122 and the second support member 20 are slidably disposed.

[0041] In this embodiment, the second sub-part 122 and the second support member 20 are slidably disposed, meaning that the second sub-part 122 and the second support member 20 are independent of each other and are not directly connected. In this case, when the state of the support assembly 100 changes, the protruding structure 23 can have a larger sliding distance relative to the groove structure 13, thereby improving the stress relief degree and further enhancing the bending performance of the support assembly 100.

[0042] In some embodiments, please refer to Figure 12The first curved portion 12 includes a second sub-portion 122. In the flattened state, a groove structure 13 penetrates the second sub-portion 122 along a first direction X. The second sub-portion 122 includes multiple segmented structures 14. In the flattened state, the multiple segmented structures 14 are spaced apart in the thickness direction Z, and the groove structure 13 is located between adjacent segmented structures 14. Among them, the multiple segmented structures 14 include a first segment 14a, and the curved support surface includes the surface of the first segment 14a facing the flexible screen 200. The first segment 14a is connected to the second support member 20.

[0043] Unlike the aforementioned embodiments, in this application embodiment, the second sub-part 122 is connected to the second support member 20, so as to... Figure 12 Taking the structure shown as an example, in the flattened state, the segmented structure 14 is located on both sides of the groove structure 13 along the thickness direction Z. One segmented structure 14 is connected to the second support member 20, while the other segmented structure 14 is slidably set with the second support member 20.

[0044] In this embodiment, by connecting a portion of the segmented structure 14 to the second support member 20, the relative positional reliability between the first support member 10 and the second support member 20 is improved. Furthermore, the remaining portion of the segmented structure 14 is slidably connected to the second support member 20, allowing the protruding structure 23 and the grooved structure 13 to slide relative to each other, thus satisfying the need for stress release and improving the bending performance of the support assembly 100. Further, considering that the first segment 14a is a segmented structure 14 used to fit with the flexible screen 200, connecting the first segment 14a to the second support member 20 allows the bent support surface to maintain a continuous structure and cover the bending area A3 in a bent state, thereby improving the support effect of the support assembly 100 on the flexible screen 200 in a bent state.

[0045] It should be noted that, in addition to Figure 12 In addition to the structure shown, in other embodiments, multiple groove structures 13 may be provided and spaced apart in the thickness direction Z. In this case, segmented structures 14 are also provided between adjacent groove structures 13. Furthermore, in order to achieve relative sliding between the protrusion structure 23 and the groove structure 13, at least one segmented structure 14 located on both sides of a single groove structure 13 needs to be slidably disposed with the second support member 20.

[0046] In some embodiments, please refer to Figure 13 The protruding structure 23 includes a plurality of protruding segments 231 spaced apart in the second direction Y, and the first direction X, the second direction Y, and the thickness direction Z intersect each other. Optionally, the first direction X, the second direction Y, and the thickness direction Z are perpendicular to each other.

[0047] Multiple protruding segments 231 are spaced apart in the second direction Y. When the support assembly 100 is in a flattened state, the projection of a single protruding segment 231 in the thickness direction Z can be a strip-shaped structure extending along the first direction X. Taking the second curved portion 22 including a third sub-portion 221 as an example, the multiple protruding segments 231 are all protruding and connected to the side of the third sub-portion 221 facing the first support member 10. Further optionally, the multiple protruding segments 231 and the third sub-portion 221 are an integral structure.

[0048] It should be noted that the dimensions and shape of the groove structure 13 are not limited in this embodiment. Optionally, the groove structure 13 is continuous in the second direction Y, that is, the plurality of protruding segments 231 are at least partially located within the same groove structure 13. Alternatively, the groove structure 13 may be provided in a plurality of locations and disposed in the second direction Y. In this case, the plurality of protruding segments 231 may be disposed in different groove structures 13.

[0049] In this embodiment, the protruding structure 23 is not continuous in the second direction Y, and includes a plurality of protruding segments 231 spaced apart. Under this design, when the state of the support component 100 changes, in addition to stress relief by the relative sliding of the protruding structure 23 in the concave direction of the groove structure 13, stress relief can also be achieved by the hollow structure between adjacent protruding segments 231, thereby further improving the bending performance of the support component 100.

[0050] Of course, in other embodiments, the size of the protrusion structure 23 in the second direction Y can also be equal to or slightly smaller than the size of the flexible screen 200 in the second direction Y. In this case, when the support assembly 100 is in a flattened state, the projection of the protrusion structure 23 in the thickness direction Z is a full-surface structure. Figure 2 The diagram shows that the size of the protrusion 23 in the second direction Y is slightly smaller than the size of the second flat portion 21 in the second direction Y, that is, the size of the protrusion 23 in the second direction Y is slightly smaller than the size of the flexible screen 200 in the second direction Y.

[0051] In some embodiments, please refer to Figure 14 and Figure 15 In the flattened state, the bottom walls of the protruding structure 23 and the groove structure 13 are spaced apart in the first direction X.

[0052] By adjusting the dimensional relationship between the protruding structure 23 and the recessed structure 13, the protruding size of the protruding structure 23 is set to be no larger than the recessed size of the recessed structure 13, thereby enabling the bottom walls of the protruding structure 23 and the recessed structure 13 to be in a flattened state. Furthermore, when the first curved portion 12 includes the third sub-portion 221, in the flattened state, the third sub-portion 221 will abut against the second sub-portion 122.

[0053] In this embodiment, by spacing the bottom walls of the protruding structure 23 and the groove structure 13 in the flattened state, the bottom walls of the protruding structure 23 and the groove structure 13 are free from compressive stress in the flattened state. This reduces the risk of deformation of the first support member 10 and the second support member 20 due to compression in the flattened state, thereby helping to improve the flatness of the curved support surface in the flattened state and enhancing the support effect of the support component 100 on the flexible screen 200.

[0054] In some embodiments, such as Figure 15 As shown, the number of groove structures 13 and protrusion structures 23 corresponds to the number of each, and there are multiple of each. The first curved portion 12 includes a second segment 14b. In the flattened state, the multiple groove structures 13 are spaced apart in the thickness direction Z of the support assembly 100. The second segment 14b is located between adjacent groove structures 13, and the first direction X intersects the thickness direction Z. The second segment 14b is slidably disposed with respect to the second support member 20.

[0055] As described above, the first segment 14a is a segmented structure 14 that can be attached to the flexible screen 200, while the second segment 14b is located between adjacent groove structures 13. Therefore, the second segment 14b and the flexible screen 200 are often spaced apart. In the flattened state, the dimension of the first segment 14a in the thickness direction Z can be equal to the dimension of the second segment 14b in the thickness direction Z, or the dimension of the first segment 14a in the thickness direction Z can be greater than or less than the dimension of the second segment 14b in the thickness direction Z. Furthermore, when multiple second segments 14b are provided, the dimensions of different second segments 14b in the thickness direction Z can be the same or different.

[0056] In this embodiment, the second segment 14b is located between adjacent groove structures 13. By not connecting the second segment 14b to the second support member 20, the second segment 14b and the second support member 20 can slide relative to each other. In this way, the protrusion structures 23 on both sides of the second segment 14b can be slidably arranged with the corresponding groove structures 13, thereby improving the deformation performance of the support assembly 100.

[0057] In some embodiments, please refer to Figure 16 In the flattened state, the second segment 14b has a dimension D1 in the thickness direction Z, the protrusion structure 23 has a dimension D2 in the thickness direction Z, the groove structure 13 has a dimension D3 in the thickness direction Z, and the spacing between adjacent protrusion structures 23 is D4. Wherein, D3 > D2; and / or, D4 > D1.

[0058] Since there are multiple groove structures 13, there are also multiple protrusion structures 23, which are spaced apart in the thickness direction Z. On this basis, not only are multiple protrusion structures 23 located at least partially within the corresponding groove structure 13, but the second segment 14b is also located at least partially between adjacent protrusion structures 23.

[0059] Therefore, in this embodiment, the dimension D3 of the groove structure 13 in the thickness direction Z is set to be larger than the dimension D2 of the protrusion structure 23 in the thickness direction Z. In the flattened state, the protrusion structure 23 will be spaced apart from at least one sidewall of the groove structure 13 in the thickness direction Z. Thus, during the state transition of the support assembly 100, in addition to sliding relative to the groove structure 13, the protrusion structure 23 can undergo a certain deformation along the thickness direction Z within the groove structure 13, thereby further improving the stress release effect and enhancing the deformation performance of the support assembly 100. Furthermore, this design can reduce the contact friction between the protrusion structure 23 and the sidewall of the groove structure 13, improving the smoothness of bending deformation.

[0060] Similarly, regarding the space between the second segment 14b and the adjacent protruding structure 23, this embodiment sets the spacing D4 between the adjacent protruding structures 23 to be greater than the dimension D1 of the second segment 14b in the thickness direction Z. Thus, in the flattened state, the second segment 14b will be spaced apart from at least one protruding structure 23 in the thickness direction Z. Therefore, during the state transition of the support assembly 100, in addition to sliding relative to the adjacent protruding structures 23, the second segment 14b can also undergo a certain deformation along the thickness direction Z between the adjacent protruding structures 23, thereby further improving the stress release effect and enhancing the deformation performance of the support assembly 100. Furthermore, this design can reduce the contact friction between the protruding structure 23 and the second segment 14b, improving the smoothness of bending deformation.

[0061] In some embodiments, please refer to Figure 17 In the flattened state, at least some of the different groove structures 13 have different dimensions in the first direction X; and / or, in the flattened state, at least some of the different protrusion structures 23 have different dimensions in the first direction X.

[0062] Considering that the degree of bending deformation of the support component 100 at different positions in the thickness direction Z is usually different, in order to match the stress relief requirements of different deformation degrees, the embodiments of this application set the dimensions of at least some different groove structures 13 in the first direction X to be different, or set the dimensions of at least some different protrusion structures 23 in the first direction X to be different, so that the sliding distance of different protrusion structures 23 relative to the groove structure 13 is different, thereby matching the stress relief requirements of different positions, which has strong flexibility and practicality.

[0063] It should be noted that the specific dimensional relationships of the multiple groove structures 13 and the multiple protrusion structures 23 need to be determined based on the actual bending situation, and this application embodiment does not impose any restrictions on this. Optionally, in the direction close to the flexible screen 200, the dimensions of the multiple groove structures 13 and the multiple protrusion structures 23 gradually increase in the first direction X.

[0064] In some embodiments, please refer to Figure 18 The first curved portion 12 includes a second sub-portion 122. In the flattened state, a groove structure 13 is disposed through the second sub-portion 122 along a first direction X. The second sub-portion 122 includes a plurality of segmented structures 14. In the flattened state, the plurality of segmented structures 14 are spaced apart in the thickness direction Z, and the groove structure 13 is located between adjacent segmented structures 14. In the flattened state and in a direction gradually moving away from the flexible screen 200, the dimensions of the plurality of segmented structures 14 in the thickness direction Z gradually decrease.

[0065] As can be seen from the accompanying drawings, the segments 14 closer to the flexible screen 200 have larger dimensions in the thickness direction Z, with the first segment 14a being the segment 14 with the largest dimension in the thickness direction Z. Optionally, in the flattened state and gradually moving away from the flexible screen 200, the dimensions of the multiple segments 14 in the thickness direction Z exhibit a gradient increasing relationship.

[0066] In this embodiment, the dimensions of the multiple segmented structures 14 in the thickness direction Z are not consistent. Instead, the closer to the flexible screen 200, the larger the dimension of the segmented structure 14 in the thickness direction Z. This design enables the first segment 14a to have a larger dimension in the thickness direction Z, thereby improving its support effect on the flexible screen 200 and further improving the molding and crease problems.

[0067] In some embodiments, please refer to Figure 19At least a portion of the groove structure 13 includes a groove body 131 and a limiting groove 132, and at least a portion of the protrusion structure 23 includes a protrusion body 232 and a limiting block 233. In the flattened state, the groove body 131 and the limiting groove 132 are connected in the thickness direction Z, and the openings of the limiting groove 132 and the groove body 131 are spaced apart in the first direction X. The limiting block 233 is connected to one side of the protrusion body 232 in the thickness direction Z. In the flattened state, the limiting block 233 is at least partially located within the limiting groove 132, and the dimension of the limiting block 233 in the first direction X is smaller than the dimension of the limiting groove 132 in the first direction X.

[0068] The protruding body 232 is a major component of the protruding structure 23, and the recessed body 131 is a major component of the recessed structure 13. In the flattened state, the protruding body 232 extends protrudingly along the first direction X, the recessed body 131 is recessed along the first direction X, the protruding structure 23 is at least partially located within the recessed body 131, and the protruding structure 23 is slidably disposed relative to the recessed body 131.

[0069] A limiting block 233 is connected to one side of the protruding body 232 along the thickness direction Z. Optionally, the limiting block 233 and the protruding body 232 are an integral structure. The dimension of the limiting block 233 in the first direction X is smaller than the dimension of the protruding body 232 in the first direction X, and the end faces of the limiting block 233 and the protruding body 232 facing away from the bottom wall of the groove body 131 are spaced apart in the first direction X. Optionally, the end face of the limiting block 233 facing the bottom wall of the groove body 131 can be flush with the end face of the protruding body 232 facing the bottom wall of the groove body 131, or the two end faces can also be spaced apart in the first direction X.

[0070] The limiting groove 132 is connected to one side of the groove body 131 along the thickness direction Z. The limiting groove 132 can be located on the side of the groove body 131 facing the flexible screen 200, or it can be located on the side of the groove body 131 away from the flexible screen 200. The groove body 131 has an opening in the first direction X opposite to its bottom wall, and the limiting groove 132 is spaced apart from the opening of the groove body 131 in the first direction X. One sidewall of the limiting groove 132 in the first direction X can be flush with the bottom wall of the groove body 131, or the two can be spaced apart.

[0071] The limiting block 233 is at least partially located within the limiting groove 132, and the dimension of the limiting block 233 in the first direction X is smaller than the dimension of the limiting groove 132 in the first direction X. Therefore, the limiting block 233 is slidably disposed relative to the limiting groove 132. The dimension of the limiting block 233 in the thickness direction Z can be equal to the dimension of the limiting groove 132 in the thickness direction Z, or the dimension of the limiting block 233 in the thickness direction Z can be smaller than the dimension of the limiting groove 132 in the thickness direction Z. This embodiment does not impose any limitations on this.

[0072] In this embodiment, at least a portion of the groove structure 13 is provided with a limiting groove 132, and at least a portion of the protrusion structure 23 is provided with a limiting block 233. The limiting block 233 is at least partially located within the limiting groove 132 and can slide relative to the limiting groove 132. Based on this, by spacing the limiting groove 132 from the opening of the groove body 131 in the first direction X, the sidewall of the limiting groove 132 in the first direction X can block the limiting block 233, preventing excessive sliding distance between the protrusion structure 23 and the groove structure 13, reducing the risk of separation between the protrusion structure 23 and the groove structure 13, and improving the reliability of the fit between the first support member 10 and the second support member 20.

[0073] It should be noted that all protruding structures 23 may be provided with limiting blocks 233. In this case, all recessed structures 13 may be provided with limiting grooves 132. Alternatively, only some protruding structures 23 may be provided with limiting blocks 233, while the remaining protruding structures 23 may not be provided with limiting blocks 233. In this case, only some recessed structures 13 may be provided with limiting grooves 132, while the remaining recessed structures 13 may not be provided with limiting grooves 132.

[0074] In some embodiments, please refer to Figure 20 The support assembly 100 also includes a blocking structure 30 disposed on the side of the first support member 10 and the second support member 20 away from the flexible screen 200. The Young's modulus of the blocking structure 30 is less than that of the first support member 10, and at least a portion of the blocking structure 30 is disposed corresponding to the bending area A3.

[0075] The blocking structure 30 is located on the side of the first support member 10 and the second support member 20 away from the flexible screen 200. In the display device 300, in addition to the support assembly 100 and the flexible screen 200, mechanical structures such as a hinge are typically included. This mechanical structure is located on the side of the support assembly 100 away from the flexible screen 200 to meet the requirements of bending deformation. Based on this, the blocking structure 30 is closer to the hinge or other mechanical structures than the first support member 10 and the second support member 20.

[0076] Young's modulus is a mechanical property of solid structures, used to measure the tensile or compressive stiffness of a structure when a longitudinal force is applied. A larger Young's modulus indicates that the structure is less likely to deform under stress, while a smaller Young's modulus indicates that the structure is more likely to deform under stress.

[0077] In this embodiment, the first support member 10 has a larger Young's modulus, which gives it greater stiffness and improves its support for the flexible screen 200. The blocking structure 30 has a smaller Young's modulus and is at least partially positioned corresponding to the bending region A3. This makes the blocking structure 30 more prone to deformation during the bending process of the support assembly 100, thereby reducing the compressive stress transmitted from the mechanical structure (such as the shaft) to the first support member 10 and the second support member 20, and improving the bending performance of the support assembly 100.

[0078] It should be noted that the specific material composition of the blocking structure 30 and the first support member 10 is not limited in the embodiments of this application. Optionally, the blocking structure 30 may include foam adhesive, and the first support member 10 may include metal materials such as steel.

[0079] Furthermore, the specific positional relationship of the blocking structure 30 relative to the first support member 10 and the second support member 20 is not limited in the embodiments of this application. Optionally, in the flattened state, the blocking structure 30 includes two parts spaced apart, one part being disposed on the first support member 10 and the other part being disposed on the second support member 20.

[0080] Similarly, in some alternative embodiments, the Young's modulus of the blocking structure 30 is less than that of the second support 20. Further alternatively, the first support 10 and the second support 20 have the same or similar Young's modulus.

[0081] In some embodiments, please refer to Figure 21 The first support member 10 includes a first surface M3 facing away from the flexible screen 200 and a first recess 15 formed by the recess of the first surface M3; and / or, the geothermal support member includes a second surface M4 facing away from the flexible screen 200 and a second recess 24 formed by the recess of the second surface M4.

[0082] Taking the first support member 10 with a first recess 15 as an example, the first surface M3 is the surface of the first support member 10 facing away from the flexible screen 200, and is also the surface of the first support member 10 facing the mechanical structure such as the rotating shaft. Based on this, by providing the first recess 15 on the first surface M3, on the one hand, while ensuring that the surface of the first support member 10 facing the flexible screen 200 remains flat, the overall weight of the first support member 10 is reduced, making it easier to bend and deform. On the other hand, when the first support member 10 bends and deforms, the presence of the first recess 15 can also help avoid interference with mechanical structures such as the rotating shaft, reducing the risk of interference between the first support member 10 and other components, and helping to improve its impact resistance.

[0083] Similarly, taking the second support member 20 with a second recess 24 as an example, the second surface M4 is the surface of the second support member 20 facing away from the flexible screen 200, and is also the surface of the second support member 20 facing the mechanical structure such as the rotating shaft. Based on this, by providing a second recess 24 on the second surface M4, on the one hand, while ensuring that the surface of the second support member 20 facing the flexible screen 200 remains flat, the overall weight of the second support member 20 is reduced, making it easier to bend and deform. On the other hand, when the second support member 20 bends and deforms, the presence of the second recess 24 can also help avoid interference with mechanical structures such as the rotating shaft, reducing the risk of interference between the second support member 20 and other components, and helping to improve its impact resistance.

[0084] It should be noted that the first recess 15 can have various positional forms. For example, the first recess 15 can completely correspond to the bending area A3, or the first recess 15 can partially correspond to the bending area A3 and partially correspond to the first straight area A1. Furthermore, in the flattened state, the projection of the first recess 15 in the thickness direction Z can overlap with the projection of the groove structure 13 in the thickness direction Z, or the projection of the first recess 15 in the thickness direction Z can be located outside the projection of the groove structure 13 in the thickness direction Z. The positional form of the second recess 24 is similar, and will not be described again in this embodiment.

[0085] Furthermore, depending on the actual needs, neither the first recess 15 nor the second recess 24 may be provided with other solid structures, or the first recess 15 and the second recess 24 may also be provided with other solid structures, so as to improve the layout integration of the display device 300.

[0086] In some embodiments, please refer to Figure 22 The first support member 10 includes a first recess 15, and the support assembly 100 also includes a blocking structure 30. The Young's modulus of the blocking structure 30 is less than that of the first support member 10, and the blocking structure 30 is located within the first recess 15. The surface of the blocking structure 30 facing away from the flexible screen 200 is coplanar with the first surface M3.

[0087] In this embodiment, the blocking structure 30 can prevent contact interference between the mechanical structure, such as the rotating shaft, and the first support member 10 during the bending and deformation of the support assembly 100, thereby achieving stress buffering and improving bending reliability. Furthermore, by placing the blocking structure 30 within the first recess 15, the adverse effects of the blocking structure 30 on the dimensions of the support structure in the thickness direction Z are reduced. Further, by making the surface of the blocking structure 30 facing away from the flexible screen 200 coplanar with the first surface M3, the side of the support assembly 100 facing away from the flexible screen 200 becomes a flat surface, improving the overall structural reliability of the support assembly 100.

[0088] Similarly, in some alternative embodiments, the second support member 20 includes a second recess 24, and the blocking structure 30 is also located within the second recess 24.

[0089] Secondly, embodiments of this application provide a display device 300, which includes a flexible screen 200 and a support component 100 as described in any of the foregoing embodiments. The flexible screen 200 includes a first flat area A1, a second flat area A2, and a bending area A3 located between the first flat area A1 and the second flat area A2. The first flat portion 11 in the support component 100 corresponds to the first flat area A1, and the second flat portion 21 in the support component 100 corresponds to the second flat area A2.

[0090] The display device 300 provided in this application embodiment has the beneficial effects of the support component 100 in any of the foregoing embodiments. For details, please refer to the foregoing description of the beneficial effects of the support component 100. This application embodiment will not repeat the details.
