[0002] Flexible displays, which offer significant advantages over traditional displays, such as bendability, flexibility, and thinness, are currently attracting widespread attention. Among them, rollable displays, which can be rolled up and unfolded according to user needs, offer a completely new human-computer interaction experience.

[0003] The flexible screen of the scroll screen is made of a multi-layer structure and has its own rebound force. Existing flexible screens often produce a lot of warping outside the bending area, resulting in arched and uneven appearance.

[0006] In a first aspect, the present disclosure provides a display device, comprising: a middle frame, the middle frame comprising a flat region and a scroll region, the scroll region being provided with a scroll shaft, the middle frame further comprising a first magnetic stripe, the first magnetic stripe being located on a side of the flat region adjacent to the scroll region, the extension direction of the first magnetic stripe intersecting the axial direction of the scroll shaft;

[0007] A display module and a support member, wherein the display module is fixed to the support member, the display module is located on a side of the support member facing away from the middle frame, the support member includes a plurality of second magnetic strips, the second magnetic strips are located in the sliding area and at least a portion of the flat area, and the second magnetic strips are magnetically attracted to the first magnetic strips;

[0008] A plurality of second magnetic strips extend along the first direction and are arranged at intervals along the second direction. The second magnetic strips include first magnetic members and second magnetic members alternately arranged along the first direction. The magnetic properties of the first magnetic members are opposite to those of the second magnetic members. The first direction and the second direction are parallel to the plane where the display module is located, and the first direction and the second direction intersect.

[0009] In a second aspect, based on the same inventive concept, the present disclosure further provides an electronic device, comprising the display device as described in the first aspect.

[0010] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art: The present disclosure provides a display device and an electronic device, comprising: a middle frame, the middle frame comprising a flat area and a sliding area, the sliding area being provided with a scroll, the middle frame further comprising a first magnetic strip, the first magnetic strip being located on a side of the flat area close to the sliding area, the extension direction of the first magnetic strip being intersected with the axial direction of the scroll; a display module and a support member, the display module being fixed to the support member, the display module being located on a side of the support member facing away from the middle frame, the support member comprising a plurality of second magnetic strips, the second magnetic strips being located in the sliding area and at least part of the flat area, the second magnetic strips being magnetically adsorbed to the first magnetic strips; the plurality of second magnetic strips extending along a first direction and being arranged at intervals along a second direction, the second magnetic strips comprising a first magnetic member and a second magnetic member alternately arranged along the first direction, the magnetic properties of the first magnetic member being opposite to those of the second magnetic member, the first direction and the second direction being parallel to the plane where the display module is located, and the first direction and the second direction being intersected.

[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0027] Figure 1 FIG. 1 is a side view of a display device provided by an embodiment of the present disclosure. Figure 2 Shown Figure 1 A partial enlarged schematic diagram, Figure 3 Shown Figure 1 Schematic diagram of the middle support. Figure 4 Shown Figure 1 Schematic diagram of the arrangement of the first magnetic stripe, Figure 5 The figure shows a schematic diagram of the position relationship between the first magnetic stripe and the second magnetic stripe provided by the embodiment of the present disclosure. Please refer to Figures 1 to 5 The present disclosure provides a display device 100, comprising: a middle frame 10, the middle frame 10 comprising a flat area 02 and a sliding area 01, the sliding area 01 being provided with a scroll 13, the middle frame 10 further comprising a first magnetic strip 11, the first magnetic strip 11 being located on a side of the flat area 02 close to the sliding area 01, the extension direction of the first magnetic strip 11 intersecting the axial direction of the scroll 13; please refer to Figure 2 , specifically, Figure 2 for Figure 1 The partially enlarged schematic diagram of the middle area 03 shows that the display device 100 further includes a display module 30 and a support member 20. The display module 30 is fixed to the support member 20. The display module 30 is located on the side of the support member 20 away from the middle frame 10. The support member 20 includes a plurality of second magnetic strips 22. The second magnetic strips 22 are located in the sliding area 01 and at least part of the flat area 02. The second magnetic strips 22 are magnetically attracted to the first magnetic strips 11. It should be noted that Figures 1 to 5 The number and spacing of the first magnetic stripes 11 and the second magnetic stripes 22 are for illustration only and are not limited in the present disclosure. They can be set according to actual needs.

[0028] Please refer to Figure 3 , multiple second magnetic strips 22 extend along the first direction D1 and are arranged at intervals along the second direction D2. The second magnetic strips 22 include first magnetic members 221 and second magnetic members 222 that are alternately arranged along the first direction D1. The magnetic properties of the first magnetic member 221 and the second magnetic member 222 are opposite. The first direction D1 and the second direction D2 are parallel to the plane where the display module 30 is located, and the first direction D1 intersects with the second direction D2.

[0029] For details, please refer to Figure 1 In an optional embodiment provided by the present disclosure, the display device 100 includes a middle frame 10, which is used to provide support for the display module 30. Optionally, the middle frame 10 can be made of metal, such as a single metal or a metal alloy. The middle frame 10 can also be made of a non-metallic material with a certain strength, such as an inorganic non-metallic material or an organic non-metallic material. This disclosure does not limit this, and the specific material can be selected according to actual needs. The middle frame 10 includes a flat area 02 and a sliding area 01. The sliding area 01 is provided with a scroll 13. It can be understood that the scroll 13 is located on one side of the middle frame 10 along the first direction D1 or the second direction D2. This disclosure does not limit this. Figure 1 The scroll 13 is located on one side of the middle frame 10 along the second direction D2 as an example. The scroll 13 is used to extend the display module 30 along the second direction D2 or the first direction D1, which is not limited in this disclosure. Figure 1 The example of the scroll 13 being used to extend the display module 30 along the second direction D2 is used for illustration.

[0030] Please refer to Figure 4The middle frame 10 further includes a first magnetic strip 11, which is located on a side of the flat area 02 close to the sliding area 01. Optionally, the first magnetic strip 11 is located at the junction of the flat area 02 and the sliding area 01, and is used to provide magnetic adsorption for the display module 30 that is at least partially located in the sliding area 01 and at least partially located in the flat area 02 during the sliding process of the display module 30, thereby reducing warping of the display module 30 during sliding and improving the flatness of the display module 30. The extension direction of the first magnetic stripe 11 intersects with the axial direction of the scroll 13. Optionally, the first magnetic stripe 11 extends along the first direction D1, and the axial direction of the scroll 13 is parallel to the second direction D2. Alternatively, the first magnetic stripe 11 extends along the second direction D2, and the axial direction of the scroll 13 is parallel to the first direction D1. Both the first direction D1 and the second direction D2 are parallel to the plane where the display module 30 is located, and the first direction D1 intersects with the second direction D2. This disclosure is not limited to this. It is sufficient that the extension direction of the first magnetic stripe 11 intersects with the axial direction of the scroll 13. Figure 4 The example in which the first magnetic strip 11 extends along the second direction D2 and the axial direction of the reel 13 is parallel to the first direction D1 is used for illustration.

[0031] The display device 100 also includes a display module 30 and a support member 20. The display module 30 is located on the side of the support member 20 facing away from the middle frame 10. The display module 30 is fixedly connected to the support member 20. The display module 30 is adsorbed by the first magnetic strip 11 on the middle frame 10 through the support member 20 to keep the display module 30 flat during the sliding process. The support member 20 includes a plurality of second magnetic strips 22, and the second magnetic strips 22 are located in the sliding area 01 and at least part of the flat area 02. It can be understood that when the setting range of the second magnetic strips 22 in the support member 20 is larger than the setting range of the first magnetic strips 11 in the middle frame 10, the second magnetic strips 22 in the support member 20 fixed on the display module 30 are displaced as the display module 30 slides. When any part of the display module 30 slides to the junction of the sliding area 01 and the flat area 02, the second magnetic strips 22 in the support member 20 located on the side of the display module 30 facing the middle frame 10 generate magnetic adsorption with the first magnetic strips 11 in the middle frame 10. By enhancing the magnetic attraction between the display module 30 and the middle frame 10, any part of the display module 30 can remain flat when it slides to the junction of the sliding area 01 and the flat area 02, thereby reducing the risk of failure of the display module 30 caused by sliding and warping.

[0032] Optionally, there may be a gap or no gap between the second magnetic stripe 22 and the first magnetic stripe 11 , which is not limited in the present disclosure. It only requires that magnetic attraction can be generated between the first magnetic stripe 11 and the second magnetic stripe 22 .

[0033] When the first magnetic stripe 11 in the middle frame 10 extends along the second direction D2, the second magnetic stripes 22 in the support member 20 extend along the first direction D1 and are arranged at intervals along the second direction D2. The drawings in this specification illustrate the example of the second direction D2 being parallel to the extension direction of the first magnetic stripe 11. In other embodiments, the second direction D2 may be parallel to the extension direction of the reel 13, and the first direction D1 may be parallel to the extension direction of the first magnetic stripe 11. This disclosure does not specifically limit the orientation of the first direction D1 and the second direction D2; it is sufficient that the extension direction of the first magnetic stripe 11 intersects the extension direction of the second magnetic stripe 22, and the arrangement direction of the second magnetic stripe 22 is the same as the extension direction of the first magnetic stripe 11.

[0034] Please refer to Figure 3 and Figure 5 , the second magnetic strip 22 also includes a first magnetic member 221 and a second magnetic member 222 alternately arranged along the first direction D1, and the magnetism of the first magnetic member 221 and the second magnetic member 222 are opposite. It can be understood that in a direction parallel to the plane where the middle frame 10 is located, multiple first magnetic strips 11 extend along the second direction D2 and are arranged at intervals along the first direction D1. There is a first gap 111 between two adjacent first magnetic strips 11. Optionally, when the first magnetic strip 11 and the first magnetic member 221 in the second magnetic strip 22 are magnetically opposite, the first magnetic strip 11 and the first magnetic member 221 in the second magnetic strip 22 arranged at intervals along the second direction D2 are adsorbed. The length of the first gap 111 along the first direction D1 is greater than or equal to the length of the second magnetic member 222 along the first direction D1, so that the first magnetic strip 11 and the first magnetic member 221 are adsorbed. The first magnetic strip 11 and the second magnetic strip 222 have the same magnetic properties, which can cause the first magnetic strip 11 and the adjacent second magnetic strip 222 to repel each other with the same polarity, which is conducive to precise alignment of magnetic attraction. Alternatively, when the first magnetic strip 11 and the second magnetic strip 22 in the second magnetic strip 22 have opposite magnetic properties, the first magnetic strip 11 and the second magnetic strip 22 in the second magnetic strip 22 arranged at intervals along the second direction D2 are attracted to each other, and the length of the first interval 111 along the first direction D1 is greater than or equal to the length of the first magnetic strip 221 along the first direction D1, which can cause the first magnetic strip 11 and the second magnetic strip 222 to have strong attraction, and the first magnetic strip 11 and the first magnetic strip 221 have the same magnetic properties, which can cause the first magnetic strip 11 and the adjacent first magnetic strip 221 to repel each other with the same polarity, which is conducive to precise alignment of magnetic attraction.

[0035] In this way, by setting the first magnetic stripe 11 in the middle frame 10, and setting the second magnetic stripe 22 in the support part 20 on the side of the display module 30 facing the middle frame 10, the second magnetic stripe 22 intersects with the extension direction of the first magnetic stripe 11, and the second magnetic stripe 22 includes a first magnetic part 221 and a second magnetic part 222 with opposite magnetic properties. The second magnetic stripe 22 has the same magnetic properties as one of the first magnetic part 221 and the second magnetic part 222, and is opposite to the magnetic properties of the other magnetic part. On the basis of the magnetic attraction between the first magnetic stripe 11 and the second magnetic stripe 22, precise alignment of the adsorption can be achieved by setting magnetic parts with different magnetic properties, thereby ensuring that the display module 30 always remains flat during the sliding process, reducing warping, and thus reducing the risk of failure of the display module 30.

[0036] Please continue to refer to Figure 5 The present disclosure provides a display device 100, in which the first magnetic strip 11 is adsorbed with the first magnetic member 221 among the plurality of second magnetic strips 22, or the first magnetic strip 11 is adsorbed with the second magnetic member 222 among the plurality of second magnetic strips 22, in a direction perpendicular to the plane where the middle frame 10 is located.

[0037] Specifically, in an optional embodiment provided by the present disclosure, when the display module 30 slides, the first magnetic member 221 in the second magnetic strip 22 at least partially overlaps with the projection of the first magnetic strip 11 on the plane where the middle frame 10 is located, and the second magnetic member 222 in the second magnetic strip 22 at least partially overlaps with the projection of the first spacer 111 on the plane where the middle frame 10 is located. The first magnetic member 221 has opposite magnetic properties to the first magnetic strip 11, and the second magnetic member 222 has the same magnetic properties as the first magnetic strip 11. The first magnetic member 221 in the second magnetic strip 22 generates magnetic adsorption with the first magnetic strip 11. Since the second magnetic member 222 between two adjacent first magnetic members 221 along the first direction D1 has the same magnetic properties as the first magnetic strip 11, the alignment accuracy between the first magnetic strip 11 and the second magnetic strip 22 can be improved by repelling like charges, thereby reducing adsorption misalignment.

[0038] In another optional embodiment provided by the present disclosure, when the display module 30 slides, the second magnetic member 222 in the second magnetic strip 22 at least partially overlaps with the projection of the first magnetic strip 11 on the plane where the middle frame 10 is located, and the first magnetic member 221 in the second magnetic strip 22 at least partially overlaps with the projection of the first spacer 111 on the plane where the middle frame 10 is located. The second magnetic member 222 has opposite magnetic properties to the first magnetic strip 11, and the first magnetic member 221 has the same magnetic properties as the first magnetic strip 11. The second magnetic member 222 in the second magnetic strip 22 generates magnetic adsorption with the first magnetic strip 11. Since the first magnetic member 221 between two adjacent second magnetic members 222 along the first direction D1 has the same magnetic properties as the first magnetic strip 11, the alignment accuracy between the first magnetic strip 11 and the second magnetic strip 22 can be improved by repelling like charges, thereby reducing adsorption misalignment.

[0039] In this way, the embodiment of the present disclosure improves the precise alignment of magnetic adsorption and reduces defects or failures caused by misalignment while maintaining the flatness of the display module 30 during the sliding process by setting one magnetic component in the second magnetic strip 22 to have opposite magnetic properties to the first magnetic strip 11 and the other magnetic component to have the same magnetic properties as the first magnetic strip 11.

[0040] Figure 6 Shown Figure 1 Another partially enlarged schematic diagram, specifically, Figure 6 for Figure 1 Please refer to the enlarged diagram of the middle area 03. Figure 2 and Figure 6 The present disclosure provides a display device 100, wherein the support member 20 includes a support layer 21, the support layer 21 is located on the side of the second magnetic strip 22 facing the display module 30, and the second magnetic strip 22 is located on the side of the support layer 21 facing the middle frame 10; the second magnetic strip 22 at least partially protrudes from the support layer 21.

[0041] Specifically, in an optional embodiment provided by the present disclosure, the display device 100 includes a display module 30, a support member 20, and a middle frame 10. The support member 20 is fixed to the display module 30. The support member 20 is located on the side of the display module 30 facing the middle frame 10. The middle frame 10 includes a first magnetic strip 11. The support member 20 includes a second magnetic strip 22. The second magnetic strip 22 generates magnetic adsorption with the first magnetic strip 11. The support member 20 also includes a support layer 21. The support layer 21 is located on the side of the second magnetic strip 22 facing the display module 30. The support layer 21 is used to provide support for the display module 30. The support layer 21 includes a metal material or a non-metallic material. The present disclosure does not limit this. The second magnetic strip 22 at least partially protrudes from the support layer 21. Optionally, please refer to Figure 2 The second magnetic strip 22 can be located on the side of the support layer 21 facing the middle frame 10, and the second magnetic strip 22 is fixed on the support layer 21, so that the second magnetic strip 22 and the first magnetic strip 11 in the middle frame 10 can be magnetically adsorbed; optionally, please refer to Figure 6 The second magnetic strip 22 can be at least partially embedded in the support layer 21, and the second magnetic strip 22 can at least partially protrude from the support layer 21. This can facilitate magnetic attraction between the second magnetic strip 22 and the first magnetic strip 11 in the middle frame 10, thereby reducing the overall thickness of the display device 100. Thus, by configuring the second magnetic strip 22 to at least partially protrude from the support layer 21, the second magnetic strip 22 can be magnetically attracted to the first magnetic strip 11 while reducing the height of the second magnetic strip 22 protruding from the support layer 21, thereby reducing the overall thickness of the display device 100. This facilitates thinning of the display device 100.

[0042] Please continue to refer to Figure 1 、 Figure 2 and Figure 6The present disclosure provides a display device 100 , wherein a first magnetic strip 11 is embedded in a middle frame 10 , and a surface of the first magnetic strip 11 facing the support 20 and a surface of the middle frame 10 facing the support 20 are located in the same plane.

[0043] Specifically, in an optional embodiment provided by the present disclosure, the middle frame 10 includes a first magnetic strip 11, which is located on a side of the flat area 02 close to the sliding area 01. In a direction parallel to the plane where the middle frame 10 is located, the first magnetic strip 11 extends along the second direction D2 and is arranged at intervals along the first direction D1. The side surface of the first magnetic strip 11 facing the support member 20 and the side surface of the middle frame 10 facing the support member 20 are located in the same plane, that is, the first magnetic strip 11 is embedded in the middle frame 10, and the first magnetic strip 11 does not protrude from the side surface of the middle frame 10 facing the support member 20. When the display module 30 slides along the middle frame 10, compared with the case where the first magnetic strip 11 protrudes from the middle frame 10, the display module 30 is more likely to cause jamming or obstruction during sliding. In the embodiment of the present disclosure, by setting the first magnetic strip 11 not to protrude from the side surface of the middle frame 10 facing the support member 20, the smoothness of the sliding of the display module 30 can be ensured based on the magnetic adsorption between the first magnetic strip 11 and the second magnetic strip 22. In this way, by setting the side surface of the first magnetic strip 11 facing the support member 20 to be in the same plane as the side surface of the middle frame 10 facing the support member 20, the smoothness of the sliding of the display module 30 can be ensured while reducing the jamming or blockage during the sliding process, further improving the sliding smoothness and improving the user experience.

[0044] Figure 7 Shown Figure 4 Cross-section along A-A', Figure 8 Shown Figure 1 For another top view of the middle frame, please refer to Figure 7 and Figure 8 The present disclosure provides a display device 100 , wherein a middle frame 10 includes a card slot 12 , a first magnetic strip 11 is located in the card slot 12 , and the card slot 12 is used to limit the first magnetic strip 11 from escaping.

[0045] For details, please refer to Figure 7 In an optional embodiment provided by the present disclosure, the middle frame 10 includes a card slot 12, and the first magnetic strip 11 is located in the card slot 12. Optionally, the cross-section of the card slot 12 can be a similar structure with a narrow top and a wide bottom, which is used to reduce the first magnetic strip 11 from being lifted up by the magnetic adsorption force and thus separated from the middle frame 10 by setting a smaller opening. The cross-sectional shape of the slot can be trapezoidal, wedge-shaped, etc. The present disclosure does not limit the shape of the card slot 12, as long as the card slot 12 can limit the first magnetic strip 11 from escaping. Optionally, please refer to Figure 8The card slot 12 may also include a limiting structure 121. The limiting structure 121 may be, for example, a narrowed portion of the card slot 12 opening. The limiting structure 121 may press the first magnetic strip 11 in the card slot 12, reducing the first magnetic strip 11 from being lifted up by the magnetic adsorption force and thus detaching from the middle frame 10. The present disclosure does not limit the structure or form of the card slot 12 and the limiting structure 121. It only needs to limit the first magnetic strip 11 from escaping. In this way, by providing the card slot 12 in the middle frame 10, the first magnetic strip 11 is located in the card slot 12, and by reducing the first magnetic strip 11 from escaping from the middle frame 10, the adsorption reliability of the first magnetic strip 11 is ensured, thereby ensuring the stability of the magnetic adsorption force.

[0046] Figure 9 Shown Figure 1 Another partially enlarged schematic diagram, specifically, Figure 9 for Figure 1 Please refer to the enlarged diagram of the middle area 03. Figure 9 The present disclosure provides a display device 100, which further includes a friction-reducing layer 40. The friction-reducing layer 40 is located between the middle frame 10 and the support member 20. The material of the friction-reducing layer 40 includes a thermoplastic polyester material or a pressure-sensitive adhesive.

[0047] Specifically, in an optional embodiment provided by the present disclosure, the display device 100 includes a middle frame 10, a support member 20, a display module 30 and a friction-reducing layer 40, wherein the support member 20 is located between the middle frame 10 and the display module 30, and the friction-reducing layer 40 is located on the side of the support member 20 facing the middle frame 10. Optionally, the friction-reducing layer 40 may at least partially cover the middle frame 10 to reduce the friction of the display module 30 in the sliding roll. Optionally, the friction-reducing layer 40 may be a low-friction coefficient material, such as a thermoplastic polyester material or a pressure-sensitive adhesive, wherein the thermoplastic polyester material may be polyethylene terephthalate (PET), etc., or other materials, which are not limited in this disclosure. The thermoplastic polyester material or pressure-sensitive adhesive may also be modified to further reduce the friction coefficient, such as by adding a slip agent, a lubricant, carbon black, etc., which are not limited in this disclosure. The friction-reducing layer 40, made of a low-friction material, can adjust the friction coefficient of the display module 30 during sliding. The friction-reducing layer 40 has a certain thickness, further increasing the distance between the first magnetic strip 11 and the second magnetic strip 22. The friction force can be adjusted by increasing the distance between the magnetic strips. This disclosure does not limit the thickness of the friction-reducing layer 40, and the thickness can be set according to actual needs. Thus, by providing the friction-reducing layer 40, made of a low-friction material, between the middle frame 10 and the support member 20, on the one hand, the distance between the first magnetic strip 11 and the second magnetic strip 22 can be increased to reduce the friction between them. On the other hand, the friction coefficient of the display module 30 during the sliding process can be adjusted by the material properties of the friction-reducing layer 40 itself, thereby adjusting the friction force and reducing wear on various components.

[0048] Please continue to refer to Figure 9 The present disclosure provides a display device 100, comprising a heat dissipation portion 23 between adjacent second magnetic stripes 22 along a second direction D2, wherein a side surface of the heat dissipation portion 23 facing the middle frame 10 and a side surface of the second magnetic stripe 22 facing the middle frame 10 are located in the same plane.

[0049] Specifically, in an optional embodiment provided by the present disclosure, the support member 20 includes a second magnetic strip 22, which extends along a first direction D1 and is arranged along a second direction D2. The support member 20 also includes a support layer 21, with the second magnetic strip 22 at least partially protruding from the support layer 21. A heat dissipation portion 23 is provided between two adjacent second magnetic strips 22 along the second direction D2, and the surface of the heat dissipation portion 23 facing the middle frame 10 is coplanar with the surface of the second magnetic strip 22 facing the middle frame 10. That is, the heat dissipation portion 23 is flush with the surface of the second magnetic strip 22 facing the middle frame 10. Optionally, the heat dissipation portion 23 includes a heat dissipation material, which can be a material having heat dissipation function, such as silicone. The present disclosure does not limit the composition of the heat dissipation material; it only needs to have heat dissipation function. Providing the heat dissipation portion 23 on the side of the display module 30 facing the middle frame 10 can enhance heat distribution in the display module 30, reduce heat concentration, and ensure display stability. The heat dissipation portion 23 is flush with the surface of the second magnetic strip 22 facing the middle frame 10, ensuring heat dissipation while reducing sticking during the display module 30's sliding, thereby improving smoothness. Thus, by providing the heat dissipation portion 23 between adjacent second magnetic strips 22 along the second direction D2, heat dissipation from the display module 30 is improved, ensuring display stability. By arranging the surface of the heat dissipation portion 23 facing the middle frame 10 and the surface of the second magnetic strip 22 facing the middle frame 10 to be coplanar, smoothness of the display module 30's sliding is ensured, sticking is reduced, and the user experience is enhanced.

[0050] Please refer to Figures 1 to 9 The present disclosure provides a display device 100 , in which the magnetic attraction force between the first magnetic stripe 11 and the second magnetic stripe 22 gradually decreases along the direction from the sliding area 01 to the flat area 02 .

[0051] Specifically, in an optional embodiment provided by the present disclosure, the magnetism of the first magnetic stripe 11 gradually decreases along the second direction D2, while the magnetism of the second magnetic stripes 22 arranged at intervals along the second direction D2 remains unchanged; alternatively, the magnetism of the first magnetic stripe 11 remains unchanged along the second direction D2, while the magnetism of the second magnetic stripes 22 arranged at intervals along the second direction D2 gradually decreases; alternatively, the magnetism of the first magnetic stripe 11 gradually decreases along the second direction D2, while the magnetism of the second magnetic stripes 22 arranged at intervals along the second direction D2 gradually decreases. The reduction in magnetism can be achieved by reducing the area of ​​the magnetic stripes or changing the magnetism of the magnetic material, which is not limited by the present disclosure. The magnetic attraction force between the first magnetic stripe 11 and the second magnetic stripe 22 gradually decreases along the direction from the sliding area 01 to the flat area 02, allowing the attraction and friction between the first magnetic stripe 11 and the second magnetic stripe 22 to be adjusted in different areas, while ensuring the flatness of the display module 30 during the sliding process. In this way, by setting the magnetic adsorption force between the first magnetic strip 11 and the second magnetic strip 22 to gradually decrease along the second direction D2, the suction and friction forces in different areas between the two are set to be flexibly adjustable, while ensuring the flatness of the display module 30 during the sliding process, unnecessary friction is reduced to reduce wear.

[0052] Figure 10 Shown Figure 4 Cross-section along B-B', Figure 11 The figure shows another top view of the middle frame provided by the embodiment of the present disclosure. Please refer to Figures 1 to 11 The present disclosure provides a display device 100 , in which the magnetism of the first magnetic strip 11 gradually decreases along the direction from the sliding area 01 to the flat area 02 .

[0053] Specifically, in an optional embodiment provided by the present disclosure, the magnetism of the first magnetic stripe 11 gradually decreases along the second direction D2, that is, along the direction from the sliding area 01 to the flat area 02, the magnetism of the first magnetic stripe 11 gradually decreases along the second direction D2, so as to reduce the magnetic adsorption force between the first magnetic stripe 11 and the second magnetic stripe 22, thereby adjusting the attraction and friction between different areas of the first magnetic stripe 11 and the second magnetic stripe 22. Optionally, please refer to Figure 10 The magnetism of the first magnetic stripe 11 can be achieved by reducing the thickness of the first magnetic stripe 11, the magnetic energy product, etc., which is not limited in this disclosure. Figure 11In an optional embodiment provided herein, the width of the first magnetic stripe 11 gradually decreases or narrows along the second direction D2. By reducing the width of the first magnetic stripe 11 along the second direction D2, the magnetism of the first magnetic stripe 11 is gradually reduced, and the magnetic attraction between the first magnetic stripe 11 and the second magnetic stripe 22 is reduced, thereby adjusting the attraction and friction between different regions of the first magnetic stripe 11 and the second magnetic stripe 22. Thus, by reducing the magnetism or width of the first magnetic stripe 11 along the second direction D2, the magnetism of the first magnetic stripe 11 in the direction from the sliding area 01 to the flat area 02 can be reduced, thereby reducing the magnetic attraction between the first magnetic stripe 11 and the second magnetic stripe 22. While ensuring the flatness of the display module 30 during the sliding process, by reducing the magnetic attraction between the first magnetic stripe 11 and the second magnetic stripe 22 away from the sliding area 01, the frictional resistance between the display module 30 and the middle frame 10 is reduced, thereby reducing wear.

In some other embodiments of the present disclosure, the electronic device 200 may also be circular, elliptical or any other feasible shape, and the present disclosure does not specifically limit this.

[0056] In summary, the present disclosure provides a display device and electronic device, including: a middle frame, the middle frame including a flat area and a sliding area, the sliding area is provided with a scroll, the middle frame also includes a first magnetic strip, the first magnetic strip is located on a side of the flat area close to the sliding area, and the extension direction of the first magnetic strip intersects with the axial direction of the scroll; a display module and a support member, the display module is fixed to the support member, the display module is located on the side of the support member away from the middle frame, the support member includes a plurality of second magnetic strips, the second magnetic strips are located in the sliding area and at least part of the flat area, and the second magnetic strips are magnetically adsorbed to the first magnetic strips; the plurality of second magnetic strips extend along the first direction and are arranged at intervals along the second direction, the second magnetic strips include a first magnetic member and a second magnetic member arranged alternately along the first direction, the magnetism of the first magnetic member and the second magnetic member are opposite, the first direction and the second direction are parallel to the plane where the display module is located, and the first direction intersects with the second direction. By setting a first magnetic strip in the middle frame and setting a second magnetic strip in the support member on the side of the display module facing the middle frame, the second magnetic strip intersects with the extension direction of the first magnetic strip, and the second magnetic strip includes a first magnetic part and a second magnetic part with opposite magnetic properties. The second magnetic strip has the same magnetic properties as one of the first magnetic part and the second magnetic part, and is opposite to the magnetic properties of the other magnetic part.
