Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display module and a display device. Background Technology

[0002] With continuous breakthroughs in various display technologies, flexible displays have entered the commercialization stage, and in recent years, various terminal manufacturers have successively launched foldable and rollable display devices.

[0003] In flexible foldable display devices, to ensure good overall flatness of the display module, a relatively thin stainless steel plate is generally used as the support component. For teardrop-shaped folded display modules, the bending shape includes inward bending (bending towards the display panel) and outward bending (bending away from the display panel). To match the bending shape of the display module, the support component has a half-etched area at the outward bending section, and a half-etched groove is formed in the half-etched area. The half-etched groove is located on the side of the support component away from the display panel, and it is used to deform and release stress. Currently, the support component of this structure display module has high stress at the half-etched area and is prone to uneven stress. Summary of the Invention

[0004] In view of this, the present invention provides a display module and a display device, which aims to solve the technical problem of uneven stress in the support member at the outward bending section of the display module and improve the reliability of the display module.

[0005] The technical solution of the present invention is as follows:

[0006] On one hand, the present invention provides a display module, including a display panel and a support member, wherein the support member has a first surface and a second surface disposed opposite to each other, and the display panel is disposed on the side of the first surface away from the second surface;

[0007] The support member has a bent shaft;

[0008] Along a first direction, the support includes a non-bending area and a half-marked area located on at least one side of the bending axis, the half-marked area being located on the side of the non-bending area closer to the bending axis;

[0009] The support member is provided with a first groove, which is located in the half-etched area. The opening of the first groove faces the display panel, and the first direction intersects the bending axis.

[0010] Based on the same inventive concept, the present invention also provides a display device, including the above-described display module.

[0011] Compared with related technologies, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0012] In the display module of the present invention, the support member is provided with a first groove, which is located in the half-mark area and the opening of the first groove faces the display panel. In this way, when the support member is bent, the stress generated in the half-mark area will be released in a direction away from the center of the half-mark area, so the stress in the half-mark area is not easy to concentrate and the phenomenon of excessive local stress is not easy to occur. Therefore, by having the opening of the first groove located in the half-mark area of ​​the support member facing the display panel, the display module of the present invention can reduce the probability of excessive local stress in the half-mark area to a certain extent, thereby improving the reliability of the display module.

[0013] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0014] Other features and advantages of the invention will become clear from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. Attached Figure Description

[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0037] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] Various modifications and variations can be made to this invention without departing from its spirit or scope, as will be apparent to those skilled in the art. Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this invention can be combined with each other without contradiction.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] This invention provides a display module, including a display panel and a support member. The display panel is disposed on one side of the support member. The support member has a bending axis. Along a first direction, the support member includes a non-bending area and a half-marked area located on at least one side of the bending axis, with the half-marked area located on the side of the non-bending area closer to the bending axis. The support member is provided with a first groove located in the half-marked area, the opening of the first groove facing the display panel, and the first direction intersecting the bending axis. Thus, when the support member is bent, the stress generated at the half-marked area will be released in a direction away from the center of the half-marked area, making it less likely for stress to concentrate and causing excessive local stress. Therefore, by orienting the opening of the first groove located in the half-marked area of ​​the support member towards the display panel, the display module of this invention can, to a certain extent, reduce the probability of excessive local stress in the half-marked area, thereby improving the reliability of the display module.

[0041] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the embodiments of this invention.

[0042] Figure 1 The diagram shown is a schematic representation of the display module provided in an embodiment of the present invention in a folded state. Figure 2 The diagram shown is a schematic representation of the display module provided in an embodiment of the present invention in its unfolded state. Figure 3 The image shown is a top view of a display module provided in an embodiment of the present invention; Figure 4 The diagram shown is a structural schematic of the display module provided in an embodiment of the present invention at the half-etched area of ​​the support member.

[0043] Please refer to Figures 1 to 4 The display module of the present invention includes a display panel 1 and a support member 2. The support member 2 is located on one side of the display panel 1. The support member 2 has a bending axis. Along the first direction X, the support member 2 includes a non-bending area P1 and a half-marked area W2 located on at least one side of the bending axis Z. The half-marked area W2 is located on the side of the non-bending area P1 close to the bending axis Z. The support member 2 is provided with a first groove 21. The first groove 21 is located in the half-marked area W2. The opening of the first groove 21 faces the display panel 1. The first direction X intersects with the bending axis Z.

[0044] For details, please refer to Figure 1 , Figure 2 and Figure 3 In some optional embodiments of the present invention, when the display module is folded with the bending axis Z as the axis, the display module located on one side of the bending axis Z sequentially includes an inward bending section, a smooth transition section, an outward bending section, and a non-bending section. The bending direction of the inward bending section faces the display panel 1, and the bending direction of the outward bending section faces the support member 2. Corresponding to the structure of the display module in the folded state, the support member 2 in the display module of the present invention includes a hollow area W1, a connecting area L1, a half-cut area W2, and a non-bending area P1. The hollow area W1 is located at the inward bending section of the display module, the connecting area L1 is located at the smooth transition section of the display module, the half-cut area W2 is located at the outward bending section of the display module, and the non-bending area P1 is located at the non-bending section of the display module.

[0045] Please continue to refer to this. Figure 1 , Figure 2 and Figure 3 Generally speaking, in order to ensure that the display module has good overall flatness, the support member 2 is set on one side of the display panel 1 as a whole layer, which has the function of supporting and shaping the display panel 1. When the display module is folded, the support member 2 deforms and generates a certain stress. Since there is a difference between the elastic modulus of the support member 2 and the film material of each film layer of the display panel 1, there is usually a phenomenon of uncoordinated stress deformation between the film layers during the folding process. In particular, when the stress generated by the support member 2 during the deformation process is not properly released and accumulates to a certain extent, it will lead to the phenomenon of debonding and breakage between the film layers of the display module.

[0046] Figure 5 The diagram shown is a partial structural schematic of the support component used in a display module in related technologies. Figure 6 The following is an example of using Figure 5 The diagram shows the structure of the display module of the support component at the half-cut area of ​​the support component, as shown. Figure 5As shown, in order to ensure that the support component 2' can both support and shape the module during the folding process, and to prevent excessive or uneven stress on the support component 2' during bending, which could lead to the failure of the display panel 1', the support component 2' generally includes a hollow area W1', a connecting area L1', a half-etched area W2', and a non-bending area P1'. The hollow area W1' usually has some hollowed-out structures. The hollowed-out design can reduce the stiffness of the support component 2' at the hollow area W1'. By using multiple hollowed-out structures 12' to generate cumulative deformation during the bending process of the support plate, the support component 2' can have a certain degree of flexibility and ductility. Since the bending degree at the location of the half-etched area W2' is less than that of the hollow area W1', the half-etched area W2' will have some half-etched grooves 21', the depth of which is less than the depth of the support component; for example Figure 6 As shown, the half-groove 21′ is located on the side of the support member away from the display panel 1′.

[0047] Currently, for Figure 5 The stress state of the display module structure in the folded state was analyzed. The analysis results show that the stress on the support member 2′ at the half-cut area W2′ is relatively large, which poses a risk to the display panel 1′. Further analysis revealed that when the support member 2′ is in a bent state, such as Figure 6 As indicated by the arrow, the stress in the half-mark region W2′ tends to concentrate towards the central axis of the half-mark region. Therefore, the stress at the half-mark region W2′ is difficult to release, and stress concentration is likely to occur, which can lead to larger local stress.

[0048] In view of this, the present invention proposes a display module that breaks with the conventional approach of placing the half-slot 21' of the half-slot area W2' on the side of the support member 2' away from the display panel 1, and instead places the slot of the half-slot area on the side of the support member closer to the display panel, such as... Figure 4 As shown, the opening of the first groove 21 located in the half-cut area W2 faces the display panel 1; thus, please refer to... Figure 3 When the support member 2 is bent, the stress generated at the half-mark area W2 will be released in a direction away from the center of the half-mark area. In this way, the stress at the half-mark area W2 is not easy to concentrate, and it is not easy to cause excessive local stress. Therefore, the display module of the present invention can reduce the probability of excessive local stress at the half-mark area W2 to a certain extent by facing the opening of the first groove 21 located at the half-mark area W2 of the support member towards the display panel 1, thereby improving the reliability of the display module.

[0049] It should be noted that, Figure 1 , Figure 2 and Figure 3This is merely a schematic diagram of one structure of the display module of the present invention, intended to illustrate the position and stress condition of the half-etched area W2, and is not intended to limit the structure of the display module of the present invention; in some other embodiments, the display module may have other bending shapes, such as no connecting area L1, or multiple half-etched areas W2, etc.

[0050] It should also be noted that the bending axis Z is the axis along which the display module folds, and is not a separate physical axis existing in the display module; Figure 1 , Figure 2 The bending axis Z shown should be a straight line parallel to the plane of the display module, and the direction of the bending axis Z should be perpendicular to the paper surface, represented as a point; in order to facilitate a clear and intuitive display of the bending axis Z, this invention... Figure 1 and Figure 2 The bent axis Z is represented by a dashed line.

[0051] Figure 7 As shown Figure 3 The diagram shown is a cross-sectional view of the display module at point AA. Figure 8 The diagram shown is a structural schematic of a support member in a display module provided in an embodiment of the present invention. Please refer to it. Figure 7 and Figure 8 In some optional embodiments of the present invention, there are multiple first grooves 21, which are arranged along a first direction X and extend along a second direction Y. Two adjacent first grooves 21 along the first direction X are provided with first support ribs 22; the second direction Y is parallel to the bending axis z.

[0052] Specifically, please combine Figure 1 , Figure 4 , Figure 7 and Figure 8 When the display module bends, the support member 2 deforms, bending away from the display panel 1 at the half-mark area W2. Therefore, the support member 2 experiences stress at the half-mark area W2 due to deformation. The support member 2 in the display module of this invention has multiple first grooves 21 opening towards the display panel 1 at the half-mark area W2. As mentioned above, the first grooves 21 opening towards the display panel 1 have the function of releasing stress and avoiding localized stress concentration. Also as mentioned above, the support member 2 in this invention supports and shapes the display panel 1; therefore, the arrangement of the first grooves 21 needs to consider not only stress release but also the necessary rigidity of the support member 2. Figure 4 As shown, when the support member 2 is bent, the stress generated at the half-mark area W2 will be released in a direction away from the center of the half-mark area W2. Therefore, as Figure 7 and Figure 8As shown, the plurality of first grooves 21 in this invention are arranged along the first direction X. Thus, the arrangement direction of the first grooves 21 is relatively consistent with the stress release direction, which can make the stress release better. In addition, the first grooves 21 extend along the second direction Y, which is parallel to the bending axis Z. The support member 2 is more likely to deform at the half-marked area W2. Thus, the depth of the first grooves 21 can be relatively shallow, which can take into account the rigidity of the support member 2 at the half-marked area W2. Furthermore, the structure of the first grooves 21 arranged along the first direction X and extending along the second direction Y in this invention is relatively regular and easy to process.

[0053] It should be noted that, Figure 7 and Figure 8 Only one structural form of the support member 2 is given to illustrate the opening, arrangement, and extension direction of the first groove 21 in the half-marked area W2. However, the structure of the support member 2 in the half-marked area W2 of the present invention is not limited to this. Figure 8 The structure shown, as in practical applications, based on the ideas of the present invention, the structure of the support member 2 at the half-marked area W2 can also take many forms. For example, multiple first grooves 21 are arranged in an array, including multiple groove columns arranged along the first direction X, each groove column including multiple first grooves 21 arranged along the second direction Y, and each first groove 21 extending along the second direction Y.

[0054] Figure 9 The diagram shown is a structural schematic of a display module provided in an embodiment of the present invention. Please refer to it. Figure 9 In some optional embodiments of the present invention, at least a portion of the first support rib 22 has a gap d between it and the display panel 1.

[0055] Specifically, please combine Figure 1 , Figure 4 and Figure 9 When the display module is folded, the support member 2 will bend away from the display panel 1 at the half-mark area W2. A relatively large stress will be generated on the side of the half-mark area W2 facing the display panel 1. If the first support rib 22 is in contact with the display panel at this time, the stress is likely to be transmitted to the display panel 1, causing the display panel 1 to be stressed and potentially damaged. In the structural design of the display module, the present invention maintains a gap d between the first support rib 22 and the display panel. This serves two purposes: firstly, it avoids the stress generated during bending from being transmitted to the display panel; secondly, the gap d between the first support rib 22 and the display panel 1 also facilitates stress release.

[0056] Furthermore, in some embodiments of the present invention, the first support rib 22 may be the groove wall between two adjacent first grooves 21, and the gap between the first support rib 22 and the display panel 1 may be achieved by providing a groove on the side of the half-etched area W2 facing the display panel 1.

[0057] Figure 10 The diagram shown is a partial structural diagram of a support component in a display module provided by an embodiment of the present invention. Figure 11 As shown Figure 10 BB cross-section; Figure 12 The diagram shown is a partial structural diagram of a support component in a display module provided by an embodiment of the present invention. Figure 13 The diagram shown is a schematic diagram of a partial area of ​​the support component in the display module provided in an embodiment of the present invention.

[0058] It should be noted that, Figure 8 , Figure 10 , Figure 12 and Figure 13 These are all schematic diagrams of a partial area of ​​the support component in the display module. The first grooves 21 shown in the figures are all semi-grooves, and the depth of each first groove 21 is less than the thickness of the support component 2. Figure 8 , Figure 10 , Figure 12 and Figure 13 When understanding the structure of the support shown, it can be combined with... Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 14 , Figure 15 , Figure 16 and Figure 17 .

[0059] Please refer to Figures 10 to 13 In some optional embodiments of the present invention, the support member 2 further includes a connecting groove 23, which is located in the half-cut area W2, and at least a portion of the connecting groove 23 is formed at the first support rib 22.

[0060] Specifically, please combine Figure 1 , Figure 4 , Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 13 When the display module is folded, the support member 2 will bend away from the display panel 1 at the half-mark area W2. A relatively large stress will be generated on the side of the half-mark area W2 facing the display panel 1. Some of the stress will be released through the first groove 21, and some stress will be transmitted through the area of ​​the half-mark area W2 where the first groove 21 is not located. At this time, if... Figure 8As shown, if the connecting groove 23 is not opened at the first support rib 22, the stress will be concentrated in a strip shape at the first support rib 22. The purpose of opening the connecting groove 23 at the first support rib 22 in this invention is to interrupt the stress propagation at the first support rib 22 and avoid stress concentration in a strip shape.

[0061] Please continue to refer to this. Figures 10 to 13 In some alternative embodiments of the invention, at least a portion of the connecting groove 23 overlaps with at least a portion of the first groove 21.

[0062] Specifically, as mentioned above, the function of the connecting groove 23 is to interrupt the stress propagation at the first support rib 22. At the same time, the connecting groove 23 also has the function of releasing stress. Similarly, one of the functions of the first groove 21 is also to release stress. In this invention, at least a portion of the connecting groove 23 coincides with at least a portion of the first groove 21. That is to say, the connecting groove 23, which has the function of releasing stress, is connected with the first groove 21, which has the function of releasing stress. Thus, compared with the state where the connecting groove 23 and the first groove 21 are not connected to each other, the space for stress release is expanded, and the stress of the support member 2 at the half-marked area W2 will be better dispersed, which helps to avoid local stress concentration.

[0063] In some preferred embodiments of the present invention, such as Figure 10 As shown, the connecting groove 23 includes multiple first sub-connecting grooves 231 and multiple second sub-connecting grooves 232. The first sub-connecting grooves 231 are located at the first supporting rib 22, and the second sub-connecting grooves 232 partially overlap with the first grooves 21. The first sub-connecting grooves 231 and the second sub-connecting grooves 232 are spaced apart and connected to each other. Thus, the connecting groove 23 and the multiple first grooves 21 form a large stress relief space, helping to avoid localized stress concentration. It should be noted that... Figure 10 , Figure 12 and Figure 13 To clearly illustrate the position of the connecting slot 23, a large dashed box is used to represent the setting area of ​​a connecting slot 23, a small dashed box represents the position of the first sub-connecting slot 231, and another small dashed box represents the position of the second sub-connecting slot 232.

[0064] Please continue to refer to this. Figure 10 , Figure 12 and Figure 13 In some optional embodiments of the present invention, there are multiple connecting slots 23, and the multiple connecting slots 23 are arranged along the second direction Y.

[0065] Specifically, in some preferred embodiments of the present invention, the connecting groove 23 includes a plurality of first sub-connecting grooves 231 and a plurality of second sub-connecting grooves 232, wherein the first sub-connecting grooves 231 are formed at the first support rib 22, and the second sub-connecting grooves 232 are formed at the first groove 21. The first sub-connecting grooves 231 and the second sub-connecting grooves 232 are spaced apart and connected in series. Furthermore, a plurality of connecting grooves 23 may be arranged along the second direction Y, thus forming a larger stress relief space with a mesh-like structure between the plurality of first grooves 21 and the plurality of connecting grooves 23. Therefore, the arrangement of the plurality of connecting grooves 23 along the second direction Y helps to disperse stress across the entire support surface and avoids localized stress concentration.

[0066] Please continue to refer to this. Figure 12 In some optional embodiments of the present invention, one end of two adjacent connecting slots 23 is connected, and the two adjacent connecting slots 23 have an included angle α, where 15° < α < 90°.

[0067] Specifically, as mentioned above, multiple connecting grooves 23 are arranged along the second direction Y, forming a larger stress release space with a mesh-like structure between the multiple first grooves 21 and the multiple connecting grooves 23. Based on this, one end of two adjacent connecting grooves 23 is connected, and the two adjacent connecting grooves 23 have an included angle α, 15° < α < 90°. Thus, not only are there direct connections between the connecting grooves 23 and the first grooves 21, but there are also direct connections between two adjacent connecting grooves 23. This allows for faster release of larger stresses, helps disperse stress across the entire surface, and avoids localized stress concentration.

[0068] Please continue to refer to this. Figure 13 In some optional embodiments of the present invention, the connecting groove 23 is an annular connecting groove.

[0069] Specifically, such as Figure 13 As shown, the annular connecting groove 23 includes multiple first sub-connecting grooves 231 and multiple second sub-connecting grooves 232. The first sub-connecting grooves 231 are formed at the first supporting ribs 22, and the second sub-connecting grooves 232 are formed at the first grooves 21 between two adjacent first supporting ribs 22. The second sub-connecting grooves 232 partially overlap with the first grooves 21. The first sub-connecting grooves 231 and the second sub-connecting grooves 232 are spaced apart and connected end to end in sequence. In this way, the connecting groove 23 and the multiple first grooves 21 form a large stress relief space, which helps to avoid local stress concentration.

[0070] Figure 14 The diagram shown is a partial structural diagram of a display module provided in an embodiment of the present invention. Please refer to it. Figure 14In some optional embodiments of the present invention, the first groove 21 is further filled with an elastic material 3.

[0071] Specifically, as mentioned above, when the display module is folded, the support member 2 will bend away from the display panel 1 at the half-mark area W2. A relatively large stress will be generated on the side of the half-mark area W2 facing the display panel 1. Some of the stress will be released through the first groove 21, and some of the stress will be transmitted through the part of the half-mark area W2 where the first groove 21 is not provided. By filling the first groove 21 with elastic material 3, the stress released at the half-mark area W2 can be buffered by the elastic material 3, thereby reducing the stress on the display panel 1.

[0072] In addition, please combine Figure 9 and 14 In some preferred embodiments of the present invention, there is a gap d between the first support rib 22 and the display panel 1. When the display module is folded, the gap d can prevent the stress generated during the bending process from being transmitted to the display panel 1. On the other hand, it is conducive to the release of stress. In addition, elastic material 3 can be filled at the position of the gap d to further buffer the stress on the display panel 1 and improve the reliability of the display panel 1.

[0073] Please continue to refer to this. Figure 7 Along the first direction X, the support member 2 also includes a hollow area W1 and a connecting area L1 located on the same side as the bending axis Z. The connecting area L1 is located between the half-cut area W2 and the hollow area L1, and the hollow area W1 is located between the bending axis Z and the connecting area L1. The hollow area W1 is provided with a through hole 24 that penetrates the support member 2 along the thickness direction of the support member 2.

[0074] Specifically, please combine Figure 1 , Figure 2 and Figure 7When the display module is folded along the bending axis Z, the display module on one side of the bending axis Z includes, in sequence, an inward bending section, a smooth transition section, an outward bending section, and a non-bending section. The bending direction of the inward bending section is towards the display panel 1, and the bending direction of the outward bending section is towards the support member 2. The hollow area W1 of the support member 2 corresponds to the inward bending section of the display module, the connecting area L1 corresponds to the smooth transition section of the display module, and the half-cut area L2 corresponds to the outward bending section of the display module. The inward bending section requires significant deformation. Therefore, the support member 2 has a through hole 24 in the hollow area W1 to facilitate the bending deformation of the support member 2 in the hollow area W1 towards the bending axis Z. Since the bending deformation in the half-cut area W2 is smaller, the depth of the first groove 21 in the half-cut area W2 is less than the thickness of the support member 2. In order to improve the strength of the support member, a connecting area L1 is provided between the hollow area W1 and the half-cut area W2. The setting of the connecting area L1 is beneficial to improving the overall strength of the support member 2.

[0075] Figure 15 The diagram shown is a partial structural diagram of a display module provided in an embodiment of the present invention. Please refer to it. Figure 15 In some optional embodiments of the present invention, the support member 2 further includes a second groove 25, which is located in the connection area L1 and the opening of the second groove 25 faces the display panel 1.

[0076] Please combine Figure 1 , Figure 4 and Figure 15 ,like Figure 4 As shown, the opening of the second recess 25 located in the connection area L1 faces the display panel 1; thus, please refer to... Figure 3 When the support 2 is bent, similar to the stress release at the half-marked area W2, the stress generated at the connection area L1 will be released in a direction away from the center of the connection area L1. In this way, stress concentration at the connection area L1 can be avoided.

[0077] In addition, please continue to refer to Figure 15 In some preferred embodiments of the present invention, since the deformation and stress at the connection area L1 are small, the width or depth of the second groove 25 or both the width and depth of the second groove 25 can be smaller than the first groove 21. Since the present invention provides a through hole 24 at the hollow area W1, a half groove 21 at the half groove area W2, and a second groove 25 with a width or depth smaller than the first groove 21 at the connection area L1, the stress distribution of the support member 2 from the hollow area W1, the connection area L1 to the half groove area W2 will be relatively uniform, which helps to improve the quality of the display module.

[0078] Please continue to refer to this. Figure 15In some optional embodiments of the present invention, there are multiple second grooves 25, which are arranged along the first direction X and extend along the second direction Y. A second support rib 26 is provided between two adjacent second grooves 25. The second direction Y is parallel to the bending axis Z. At least a portion of the second support ribs 26 have a gap d1 with the display panel 1.

[0079] Specifically, please combine Figure 1 , Figure 4 and Figure 15 When the display module is folded, the support member 2 will bend away from the display panel 1 at the connection area L1. Stress will be generated on the side of the connection area L1 facing the display panel. If the second support rib 26 is in contact with the display panel 1 at this time, the stress is likely to be transmitted to the display panel 1, causing the display panel 1 to be stressed. In the structural design of the display module, the present invention maintains a gap d1 between the second support rib 26 and the display panel. In this way, on the one hand, the stress generated during the bending process can be avoided from being transmitted to the display panel 1; on the other hand, the gap d1 between the second support rib 26 and the display panel 1 is also conducive to stress release.

[0080] Figure 16 The diagram shown is a partial structural diagram of a display module provided in an embodiment of the present invention. Please refer to it. Figure 16 In order to further buffer the stress generated by the support member 2 in the half-mark area W2 and the connecting area L1 and avoid damage to the display panel, the present invention fills the gap d1 between the second groove 25 and the second support rib 26 and the display panel 1 with elastic material 3. In this way, when the stress is released in the half-mark area W2 and the connecting area L1, it can be buffered by the elastic material 3, thereby reducing the stress on the display panel 1.

[0081] Figure 17 The diagram shown is a partial structural diagram of a display module provided in an embodiment of the present invention. Please refer to it. Figure 17 In some embodiments of the present invention, along the first direction X, the width of the first groove 21 near the middle position of the half-marked area W2 is wider than the width of the first groove 21 away from the middle position of the half-marked area W2; and / or, along the first direction X, the depth of the first groove 21 near the middle position of the half-marked area W2 is deeper than the depth of the first groove 21 away from the middle position of the half-marked area W2.

[0082] Specifically, widening or deepening the width of the first groove 21 helps to expand the stress release space, which in turn helps to release stress. Furthermore, since the stress at the half-mark area W2 decreases from the center to both sides along the first direction X, this invention designs the width of the first groove 21 near the center of the half-mark area W2 to be wider than the width of the first groove 21 away from the center of the half-mark area W2; and / or, along the first direction X, makes the depth of the first groove 21 near the center of the half-mark area W2 greater than the depth of the first groove 21 away from the center of the half-mark area W2. This allows for a more uniform stress distribution and lower stress in the support member 2 at the half-mark area W2, while also helping to ensure the strength of the support member 2.

[0083] Based on the same inventive concept, the present invention also provides a display device, please refer to [reference needed]. Figure 18 , Figure 18 The diagram shown is a structural schematic of a display device provided in an embodiment of the present invention.

[0085] In summary, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0086] By orienting the opening of the first groove 21 located at the half-mark area W2 of the support member toward the display panel 1, the display module of the present invention can reduce the probability of excessive local stress at the half-mark area W2 to a certain extent, thereby improving the reliability of the display module.
