[0024] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there may be intervening elements. Further, when a layer is referred to as being "under" another layer, it can be directly under or there may be one or more intervening elements. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there may be one or more intervening elements.

[0027] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0028] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present application.

[0029] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0030] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0031] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0032] As mentioned in the background technology section, for a display device with a foldable screen, after the display device is folded, it can be more convenient for users to carry and store, and after the display device is unfolded, it can provide users with a larger display area when using it, thereby improving the user experience. However, since the display device needs to be folded and unfolded frequently, the bend of the foldable screen is easily damaged, resulting in the bend of the display device being easily peeled off.

[0033] It should be noted that the display module, display device, etc. of the present application are all display structures with a folding function. The display panel in the display device of the present application is the folding screen in the related art.

[0034] Based on the inventor's research, in the related technology, a display device with a folding function includes a foldable display panel and a support structure for supporting the display panel. On the one hand, the support structure can provide stable mechanical support for the folding and unfolding of the display panel, ensuring a smooth folding process and reducing damage to the display panel. For example, a common hinge structure is an important part of the support structure, which connects different parts of the display panel so that the display panel can be folded and unfolded in the designed manner. On the other hand, in the folded state, the support structure can protect the display panel from damage such as external force squeezing, and prevent the display panel from creases, breakage and other problems.

[0035] In addition, it should be supplemented that the display panel and the supporting structure may be directly connected, or other film layers may be provided in the display panel and the supporting structure to achieve indirect connection between the display panel and the supporting structure.

[0036] In the process of folding or unfolding synchronously with the display panel, the support structure in the related technology is affected by its own structure and shape because the support structure is at the bending part of the display device. At the same time, the support structure and the display panel are made of different materials and are affected by the contact part between the support structure and the display panel, resulting in greater stress in the support structure during the bending process.

[0037] Furthermore, in the related art, a groove is formed on a side of the support structure away from the display panel through a half-engraving process, thereby reducing the stress of the support structure during the bending process.

[0038] Among them, the half-engraving process is a processing technology for partially etching or cutting related materials. In a flexible foldable display device, in order to ensure that the display device has good overall flatness, the display device generally uses a thinner stainless steel plate as a supporting structure. For a display device with a teardrop-shaped bending shape, its supporting structure will be provided with a half-engraved area at the outward bending section, and a half-engraved groove will be opened in the half-engraved area. These half-engraved grooves are used to deform and release stress. When the supporting structure is bent, it helps to reduce the probability of excessive local stress in the half-engraved area, thereby improving the reliability of the display device.

[0039] However, the inventors also discovered that by making grooves on the side of the support structure away from the display panel, although the stress of the support structure during the bending process can be reduced, on the one hand, during the bending process of the display device, the stress of the support structure will change unevenly because the side of the support structure facing the display panel and the side away from the display panel are subjected to different forces and bending deformation states. On the other hand, since the bending deformation states of the side of the support structure away from the display panel are also different at different positions during the bending process, the stress of the support structure will also change unevenly. Furthermore, during the bending process of the support structure, although the stress of the side of the support structure away from the display panel can be reduced by making grooves through a half-engraving process, it will still cause uneven stress of the support structure, thereby causing peeling between the support structure and the display panel or other film layers.

[0040] Based on the above technical problems, the inventors have discovered that by using a half-engraving process to make grooves on both the side of the support structure away from the display panel and the side facing the display panel, and the groove sizes on at least one of the sides are different, the stress generated during the bending process can be reduced while the stress on both sides and inside the support structure can be evenly released, thereby reducing the risk of peeling between the support structure and the display panel or other film layers.

[0041] Specifically, the support assembly provided by the embodiment of the present application includes a support member, and the support member has a first surface and a second surface arranged opposite to each other along the thickness direction. A first groove is arranged on the first surface, and a second groove is arranged on the second surface. Further, a plurality of first recessed parts are arranged in the first groove, and a plurality of second recessed parts are arranged in the second groove. At the same time, since the sizes of at least two first recessed parts are different along the first direction, and / or the sizes of at least two second recessed parts are different, during the bending process of the support member, the stress generated during the bending process can be evenly released through the first recessed parts and the second recessed parts of different sizes, thereby reducing the risk of peeling between the support assembly and the display panel or other film layers in the display device during the bending process.

[0042] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] See also Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 1 provided in the embodiment of the present application includes a bending area 1a and a non-bending area 1b, and the bending area 1a and the non-bending area 1b are arranged along the first direction. The support assembly 1 includes a support member 11. The support member 11 includes a first surface 11a and a second surface 11b arranged opposite to each other along the thickness direction of the support member 11; the first surface 11a located in the bending area 1a is provided with a first groove 111, and the second surface 11b located in the bending area 1a is provided with a second groove 112; the first groove 111 includes a plurality of first recessed portions 1111 arranged at intervals, and the second groove 112 includes a plurality of second recessed portions 1121 arranged at intervals; along the first direction, at least two first recessed portions 1111 have different sizes, and / or at least two second recessed portions 1121 have different sizes. Wherein, the first direction intersects with the thickness direction of the support member 11.

[0044] It should be noted that the first direction is Figure 1 The X direction of the support member 11 is Figure 1 in the Y direction.

[0045] Among them, the support component 1 is used to support the display panel in the display device. The support component 1 includes a bending area 1a and a non-bending area 1b, and the bending area 1a and the non-bending area 1b are arranged along the first direction. The bending area 1a of the support component 1 is the part where the bending occurs in the support component 1, and the bending area 1a of the support component 1 can be folded or unfolded synchronously with the display panel, so that the display panel can be protected from damage such as external force squeezing by the bending area 1a of the support component 1, and the display panel can be prevented from creases, breakage and other problems. At the same time, the non-bending area 1b of the support component 1 is the part where the bending does not occur in the support component 1, and is set corresponding to the part where the bending does not occur in the display panel. On the one hand, it can provide stable mechanical support for the display panel to ensure a smooth folding process of the display panel and reduce damage to the display panel; on the other hand, it can provide support for the display panel to protect the normal use of the display panel.

[0046] Specifically, the support member 11 has a first surface 11a and a second surface 11b that are arranged opposite to each other along the thickness direction. A first groove 111 is arranged on the first surface 11a, and a second groove 112 is arranged on the second surface 11b. Further, a plurality of first recessed portions 1111 are arranged in the first groove 111, and a plurality of second recessed portions 1121 are arranged in the second groove 112. At the same time, since the sizes of at least two first recessed portions 1111 are different along the first direction, and / or the sizes of at least two second recessed portions 1121 are different, during the bending process of the support member 11, the stress generated during the bending process can be evenly released through the first recessed portions 1111 and the second recessed portions 1121 of different sizes, thereby reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0047] It should be supplemented that the direction intersecting the first direction and the thickness direction of the support member 11 is defined as the second direction. Figure 1 As shown, along the second direction, the first recessed portion 1111 and the second recessed portion 1121 are both partially disposed on the first surface 11a and the second surface 11b, that is, the lines of the first recessed portion 1111 and the second recessed portion 1121 are shown as dotted lines. Figure 2 As shown, along the second direction, the first recessed portion 1111 and the second recessed portion 1121 penetrate the two side surfaces of the support member 11 along the second direction, that is, the lines of the first recessed portion 1111 and the second recessed portion 1121 are shown as solid lines. That is, the present application does not limit the specific positions of the first recessed portion 1111 and the second recessed portion 1121 along the second direction.

[0048] It should be further explained that, in the present application, along the first direction, the sizes of at least two first recessed portions 1111 are different, and / or, the sizes of at least two second recessed portions 1121 are different, and the and / or here means that along the first direction, the sizes of at least two first recessed portions 1111 are different, or along the first direction, the sizes of at least two second recessed portions 1121 are different, or along the first direction, the sizes of at least two first recessed portions 1111 and at least two second recessed portions 1121 are different, that is, in the present application, as long as the sizes of the recessed portions on at least one side in the thickness direction of the support member 11 are different, the description will not be repeated here. At the same time, for the convenience of explanation, in the embodiments of the present application, the examples in which the sizes of at least two first recessed portions 1111 and at least two second recessed portions 1121 are different along the first direction are used for explanation.

[0049] Furthermore, during the bending process of the support member 11, the bending deformation states of different positions on any side of the first surface 11a or the second surface 11b are different, resulting in uneven stress changes on any side of the first surface 11a or the second surface 11b of the support member 11. Since the sizes of the recessed portions on at least one side of the thickness direction of the support member 11 along the first direction are different, the stress generated at different positions on any side of the first surface 11a or the second surface 11b of the support member 11 during the bending process can be evenly released through the first recessed portions 1111 or the second recessed portions 1121 of different sizes, thereby reducing the deformation of any side of the first surface 11a or the second surface 11b of the support member 11 during the bending process, and evenly releasing the stress generated on any side of the first surface 11a or the second surface 11b of the support member 11 during the bending process, thereby avoiding the inability to dissipate the bending stress, thereby reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0050] In addition, during the bending process of the support member 11, the bending deformation states at different positions on both sides of the first surface 11a and the second surface 11b are also different. Since the sizes of at least two first recessed portions 1111 and at least two second recessed portions 1121 are different along the first direction, the stress generated at different positions on both sides of the first surface 11a and the second surface 11b of the support member 11 during the bending process can be evenly released through the first recessed portions 1111 and the second recessed portions 1121 of different sizes, thereby further reducing the deformation of the first surface 11a and the second surface 11b of the support member 11 during the bending process, and evenly releasing the stress generated on both sides of the first surface 11a and the second surface 11b of the support member 11 during the bending process, thereby avoiding the inability to dissipate the bending stress, thereby further reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0051] In addition, since the sizes of at least two first recessed portions 1111 and at least two second recessed portions 1121 are different along the first direction, that is, along the first direction, the numbers of the first recessed portions 1111 and the second recessed portions 1121 are both multiple, during the process of synchronous folding or unfolding of the support member 11 and the display panel, the probability of excessive local stress on the first surface 11a and the second surface 11b can be reduced by the multiple first recessed portions 1111 and the second recessed portions 1121, thereby improving the reliability of the display device.

[0052] In summary, the support assembly 1 provided in the embodiment of the present application includes a support member 11, and the support member 11 has a first surface 11a and a second surface 11b arranged opposite to each other in the thickness direction. A first groove 111 is arranged on the first surface 11a, and a second groove 112 is arranged on the second surface 11b. Further, a plurality of first recessed portions 1111 are arranged in the first groove 111, and a plurality of second recessed portions 1121 are arranged in the second groove 112. At the same time, since the sizes of at least two first recessed portions 1111 are different along the first direction, and / or the sizes of at least two second recessed portions 1121 are different, the stress generated during the bending process of the support member 11 can be evenly released through the first recessed portions 1111 and the second recessed portions 1121 of different sizes, thereby reducing the risk of peeling between the support assembly 1 and the display panel or other film layers in the display device during the bending process.

[0053] In some embodiments, see Figure 4 As shown, along the first direction, the sizes of the plurality of first recessed portions 1111 gradually increase or decrease.

[0054] In this way, since the sizes of the multiple first recessed portions 1111 gradually increase or decrease along the first direction, during the bending process of the support member 11, the stress generated in the bending process can be evenly released along the first direction through the multiple first recessed portions 1111 that gradually increase or decrease, thereby improving the bending performance of the support member 11.

[0055] In some embodiments, see Figure 4 As shown, along the first direction, the sizes of the plurality of second recessed portions 1121 gradually increase or decrease.

[0056] In this way, since the sizes of the multiple second recessed portions 1121 gradually increase or decrease along the first direction, during the bending process of the support member 11, the stress generated in the bending process can be evenly released along the first direction through the multiple second recessed portions 1121 that gradually increase or decrease, thereby improving the bending performance of the support member 11.

[0057] In some embodiments, see Figure 4 , Figure 5 and Figure 6 As shown, the support assembly 1 further includes a first filling piece 12 and a second filling piece 13. The first filling piece 12 is at least partially disposed in the first groove 111; the elastic modulus of the support member 11 is greater than the elastic modulus of the first filling piece 12. The second filling piece 13 is at least partially disposed in the second groove 112; the elastic modulus of the support member 11 is greater than the elastic modulus of the second filling piece 13.

[0058] In this way, since the first filling member 12 is at least partially disposed in the first groove 111, and the elastic modulus of the support member 11 is greater than the elastic modulus of the first filling member 12. The second filling member 13 is at least partially disposed in the second groove 112, and the elastic modulus of the support member 11 is greater than the elastic modulus of the second filling member 13, during the bending process of the support member 11, the stress generated by the support member 11 during the bending process on the first surface 11a can be buffered by the first filling member 12, and the stress generated by the support member 11 during the bending process on the second surface 11b can be buffered by the second filling member 13. On the one hand, the deformation of the support member 11 during the bending process can be further reduced, thereby further improving the bending performance of the support member 11. On the other hand, the first filling member 12 and the second filling member 13 will contact the display panel or other film layers in the display device, thereby providing further support for the display panel or other film layers in the display device, thereby improving the overall stability and reliability of the display device.

[0059] In some embodiments, see Figure 4 and Figure 5 As shown, the first groove 111 also includes a first connecting portion 1112, and a plurality of first recessed portions 1111 are arranged on the side of the first connecting portion 1112 facing the second surface 11b, and the plurality of first recessed portions 1111 are all connected to the first connecting portion 1112. The first filling member 12 includes a first filling portion 121 and a plurality of first protrusions 122, and the plurality of first protrusions 122 and the plurality of first recessed portions 1111 are arranged correspondingly, the first protrusions 122 are arranged in the corresponding first recessed portions 1111, and the first filling portion 121 is arranged in the first connecting portion 1112.

[0060] In this way, multiple first protrusions 122 and multiple first recessed portions 1111 can be set correspondingly, and the first filling portion 121 and the first connecting portion 1112 can be set correspondingly, so that the multiple first recessed portions 1111 can be connected through the first connecting portion 1112, and the first filling portion 121 can be connected to multiple first protrusions 122, so that the first connecting portion 1112 and the first filling portion 121 can play a role in stress transition during the bending process, which can avoid stress concentration in some of the first recessed portions 1111, and can improve the reliability of the support member 11 during the bending process.

[0061] In some embodiments, see Figure 4 and Figure 6As shown, the second groove 112 further includes a second connecting portion 1122, a plurality of second recessed portions 1121 are provided on the side of the second connecting portion 1122 facing the first surface 11a, and the plurality of second recessed portions 1121 are all connected to the second connecting portion 1122. The second filling member 13 includes a second filling portion 131 and a plurality of second protrusions 132, the plurality of second protrusions 132 and the plurality of second recessed portions 1121 are provided correspondingly, the second protrusions 132 are provided in the corresponding second recessed portions 1121, and the second filling portion 131 is provided in the second connecting portion 1122.

[0062] In this way, multiple second protrusions 132 and multiple second recessed portions 1121 can be set correspondingly, and the second filling portion 131 and the second connecting portion 1122 can be set correspondingly, so that the multiple second recessed portions 1121 can be connected through the second connecting portion 1122, and the second filling portion 131 can be connected to the multiple second protrusions 132, so that the second connecting portion 1122 and the second filling portion 131 can play a role in stress transition during the bending process, which can avoid stress concentration in some of the second recessed portions 1121, and can improve the reliability of the support member 11 during the bending process.

[0063] In some embodiments, see Figure 4 As shown, along the thickness direction of the support member 11 , the orthographic projection of the first connecting portion 1112 on the first surface 11 a at least partially overlaps with the orthographic projection of the second connecting portion 1122 on the first surface 11 a .

[0064] In this way, during the bending process of the support member 11, the first connecting portion 1112 and the second connecting portion 1122 can simultaneously buffer stress and release stress in the corresponding areas in the thickness direction of the support member 11, thereby ensuring uniform stress release on both sides of the support member 11 and reducing the risk of peeling between the support member 11 and the film layers on both sides thereof during the bending process.

[0065] In some embodiments, see Figure 7 As shown, there are multiple first grooves 111 , and the multiple first grooves 111 are arranged along the first direction.

[0066] It should be noted that the first direction in this embodiment is Figure 7 The X direction in .

[0067] In this way, since there are multiple first grooves 111, during the process of synchronous folding or unfolding of the support member 11 and the display panel, the multiple first grooves 111 can reduce the probability of excessive stress in local positions on the first surface 11a along the first direction, thereby improving the reliability of the display device.

[0068] In some embodiments, see Figure 7As shown, there are multiple second grooves 112 , and the multiple second grooves 112 are arranged along the first direction.

[0069] It should be noted that the first direction in this embodiment is Figure 7 The X direction in .

[0070] In this way, since there are multiple second grooves 112, during the process of synchronous folding or unfolding of the support member 11 and the display panel, the multiple second grooves 112 can reduce the probability of excessive stress in local positions on the second surface 11b along the first direction, thereby improving the reliability of the display device.

[0071] In some embodiments, see Figure 4 As shown, along the thickness direction of the support member 11, a plurality of first recessed portions 1111 and a plurality of second recessed portions 1121 are arranged correspondingly, and the orthographic projections of the first recessed portions 1111 on the first surface 11a overlap with the orthographic projections of the corresponding second recessed portions 1121 on the first surface 11a.

[0072] In this way, during the bending process of the support member 11, the first recessed portion 1111 and the second recessed portion 1121 can simultaneously buffer stress and release stress in corresponding areas in the thickness direction of the support member 11, thereby ensuring uniform stress release on both sides of the support member 11 and reducing the risk of peeling between the support member 11 and the film layers on both sides thereof during the bending process.

[0073] In some embodiments, see Figure 8 As shown, along the thickness direction of the support member 11, the orthographic projection of a first recessed portion 1111 on the first surface 11a is a first orthographic projection, and the orthographic projection of a second recessed portion 1121 on the first surface 11a is a second orthographic projection. There is a spacing between the first orthographic projection and the second orthographic projection, and the first orthographic projection and the second orthographic projection are alternately arranged.

[0074] It should be noted that the thickness direction of the support member 11 in this embodiment is Figure 8 in the Y direction.

[0075] In this way, during the bending process of the support member 11, the first recessed portion 1111 and the second recessed portion 1121 can buffer stress and release stress in different areas in the thickness direction of the support member 11, thereby ensuring that stress release in different areas on both sides of the support member 11 is uniform, and reducing the risk of peeling between the support member 11 and the film layers on both sides of the support member 11 during the bending process.

[0076] In some embodiments, see Fig. 9As shown, the orthographic projections of the plurality of first recessed portions 1111 on the first surface 11 a and the orthographic projections of the plurality of second recessed portions 1121 on the first surface 11 a at least partially do not overlap.

[0077] It should be noted that the thickness direction of the support member 11 in this embodiment is Fig. 9 in the Y direction.

[0078] In this way, during the bending process of the support member 11, the first recessed portion 1111 and the second recessed portion 1121 can buffer stress and release stress in different areas in the thickness direction of the support member 11, thereby further ensuring that stress release in different areas on both sides of the support member 11 is uniform, and further reducing the risk of peeling between the support member 11 and the film layers on both sides of the support member 11 during the bending process.

[0079] In some embodiments, see Figure 4 As shown, along the first direction, the size of the first recessed portion 1111 is in the range of 15 μm to 25 μm.

[0080] It should be noted that the first direction in this embodiment is Figure 4 The X direction in .

[0081] In this way, it can be avoided that the size of the first recessed portion 1111 is too small, so that the stress generated by the support member 11 during the bending process cannot be completely and evenly released. Therefore, when the size of the first recessed portion 1111 is too small, the stress of the first surface 11a of the support member 11 is not fully released, and the problem of peeling between the first surface 11a of the support member 11 and the film layer in contact with it still occurs. At the same time, if the size of the first recessed portion 1111 is too large, the main body of the support member 11 will have a smaller space, so that it cannot support the display panel, thereby affecting the overall stability of the display device. That is, the size range of the first recessed portion 1111 is 15μm-25μm, which can ensure the support effect of the support member 11 on the display panel while completely and evenly releasing the stress generated by the first surface 11a of the support member 11 during the bending process, thereby minimizing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0082] In some embodiments, see Figure 4 As shown, along the first direction, the size of the second recessed portion 1121 ranges from 15 μm to 25 μm.

[0083] It should be noted that the first direction in this embodiment is Figure 4 The X direction in .

[0084] In this way, it can be avoided that the size of the second recessed portion 1121 is too small, so that the stress generated by the support member 11 during the bending process cannot be completely and evenly released. Therefore, when the size of the second recessed portion 1121 is too small, the stress of the second surface 11b of the support member 11 is not fully released, and the problem of peeling between the second surface 11b of the support member 11 and the film layer in contact with it still occurs. At the same time, if the size of the second recessed portion 1121 is too large, the main body of the support member 11 will have a smaller space, so that it cannot support the display panel, thereby affecting the overall stability of the display device. That is, the size range of the second recessed portion 1121 is 15μm-25μm, which can ensure the support effect of the support member 11 on the display panel while completely and evenly releasing the stress generated by the second surface 11b of the support member 11 during the bending process, thereby minimizing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0085] In some embodiments, see Figure 4 As shown, along the thickness direction of the support member 11, the thickness of the support member 11 is A, the maximum dimension from the bottom of the first recessed portion 1111 to the first surface 11a is B, and the maximum dimension from the bottom of the second recessed portion 1121 to the second surface 11b is C; A, B and C satisfy the following condition: 0.2≤[1-(B+C) / A]≤0.6.

[0086] In this way, while ensuring the supporting effect of the support member 11 on the display panel, the stress generated by the support member 11 during the bending process can be completely and evenly released, thereby minimizing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0087] In some embodiments, see Figure 4 As shown, along the thickness direction of the support member 11, the thickness of the support member 11 is A, the maximum dimension from the bottom of the first recessed portion 1111 to the first surface 11a is B, and the maximum dimension from the bottom of the second recessed portion 1121 to the second surface 11b is C; A, B and C satisfy the following conditions: 20μm≤(ABC)≤30μm.

[0088] In this way, while ensuring the supporting effect of the support member 11 on the display panel, the stress generated by the support member 11 during the bending process can be further evenly released, further reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.

[0089] In some embodiments, see Figure 3As shown, the bending zone 1a includes a first sub-bending area 1a1, a second sub-bending area 1a2 and a third sub-bending area 1a3. Along the first direction, the first sub-bending area 1a1 is located between the second sub-bending area 1a2 and the third sub-bending area 1a3; the first groove 111 and the second groove 112 are both located in the second sub-bending area 1a2 and the third sub-bending area 1a3.

[0090] In this way, the first groove 111 and the second groove 112 are respectively located in different sub-bending areas along the first direction in the bending zone 1a, so that the stress generated in different sub-bending areas of the support member 11 during the bending process can be evenly released, thereby reducing the risk of peeling between different sub-bending areas in the support member 11 and corresponding areas of the display panel or other film layers in the display device during the bending process.

[0091] In some embodiments, see Figure 3 As shown, the orthographic projections of the first groove 111 and the second groove 112 on the first surface 11a do not overlap with the orthographic projections of the first sub-bending region 1a1 on the first surface 11a. The support member 11 is also provided with a plurality of through holes 113 arranged at intervals; the plurality of through holes 113 are all located in the first sub-bending region 1a1, and the plurality of through holes 113 pass through the first surface 11a and the second surface 11b.

[0092] In this way, since the multiple through holes 113 are all located in the first sub-bending area 1a1, and the multiple through holes 113 all pass through the first surface 11a and the second surface 11b, the risk of peeling off between the first sub-bending area 1a1 and the corresponding area of ​​the display panel or other film layers in the display device can be reduced during the bending process further released through the multiple through holes 113.

[0093] In some embodiments, see Figure 1 and Figure 3 As shown, there are two non-bending areas 1b, and the two non-bending areas 1b are respectively located on both sides of the bending area 1a along the first direction. The support member 11 includes a first sub-portion 11c, a second sub-portion 11d and a third sub-portion 11e arranged in sequence along the second direction; the orthographic projections of the first groove 111 and the second groove 112 on the first surface 11a are both located within the orthographic projection of the second sub-portion 11d on the first surface 11a, and do not overlap with the orthographic projection of the first sub-portion 11c on the first surface 11a and the orthographic projection of the third sub-portion 11e on the first surface 11a. Among them, the second direction intersects with the first direction and the thickness direction of the support member 11.

[0094] It should be noted that the first direction in this embodiment is Figure 3 The second direction in this embodiment is Figure 3 The Z direction in .

[0095] In this way, since the orthographic projections of the first groove 111 and the second groove 112 on the first surface 11a are both located within the orthographic projection of the second sub-section 11d on the first surface 11a, and do not overlap with the orthographic projections of the first sub-section 11c and the third sub-section 11e on the first surface 11a, during the bending process of the support member 11, the first groove 111 and the second groove 112 in the second sub-section 11d can release stress, thereby ensuring that the stress generated during the bending process is evenly released, thereby reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process. In addition, the first sub-section 11c and the third sub-section 11e can support the display panel or other film layers, thereby improving the overall stability and reliability of the display device.

[0096] In some embodiments, the number of non-bending regions 1b is two, and the two non-bending regions 1b are respectively located on both sides of the bending region 1a along the first direction. The support member 11 includes a first sub-portion 11c, a second sub-portion 11d, and a third sub-portion 11e arranged in sequence along the second direction; the first sub-portion 11c, the second sub-portion 11d, and the third sub-portion 11e are each provided with a first groove 111 and a second groove 112. The second direction intersects with the first direction and the thickness direction of the support member 11.

[0097] In this way, since the first sub-portion 11c, the second sub-portion 11d and the third sub-portion 11e are all provided with the first groove 111 and the second groove 112, during the bending process of the support member 11, the first groove 111 and the second groove 112 in the first sub-portion 11c, the second sub-portion 11d and the third sub-portion 11e can release the stress, thereby further ensuring that the stress generated during the bending process is evenly released, thereby further reducing the risk of peeling between the support component 1 and the display panel or other film layers in the display device during the bending process.
