Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a display device and an electronic device. Background Technology

[0002] Flexible displays offer significant advantages over traditional displays, including bendability, flexibility, and thinness, making them a popular choice in the industry. Rollable displays, in particular, offer a novel human-computer interaction experience by allowing users to roll them up and unroll them according to their needs.

[0003] Rollable flexible screens are made up of multiple stacked structures and have their own rebound force. Existing flexible screens often produce a lot of warping outside the bending area, resulting in an uneven arching phenomenon.

[0004] Therefore, how to ensure that the flexible screen of a rollable display remains flat outside the bending area has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a display device and an electronic device for ensuring that the flexible screen of a rollable display remains flat outside the bending area.

[0006] In a first aspect, this disclosure provides a display device, including: a middle frame, the middle frame including a flat area and a sliding area, the sliding area being provided with a scroll, the middle frame also including a first magnetic strip, the first magnetic strip being located on the side of the flat area near the sliding area, and the extending direction of the first magnetic strip intersecting the axial direction of the scroll.

[0007] The display module and the support are fixed together. The display module is located on the side of the support away from the middle frame. The support includes a plurality of second magnetic strips. The second magnetic strips are located in the sliding area and at least partially flat area. The second magnetic strips are magnetically attracted to the first magnetic strip.

[0008] Multiple second magnetic strips extend along a first direction and are spaced apart along a second direction. Each second magnetic strip includes a first magnetic element and a second magnetic element that are alternately arranged along the first direction. The first magnetic element and the second magnetic element have opposite magnetic properties. 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] Secondly, based on the same inventive concept, this disclosure also provides an electronic device, including the display device as described in the first aspect.

[0010] Compared with the prior art, the technical solution provided by the embodiments of this disclosure has the following advantages: This disclosure provides a display device and an electronic device, including: a middle frame, the middle frame including a flat area and a sliding area, the sliding area being provided with a scroll, the middle frame also including a first magnetic strip, the first magnetic strip being located on the side of the flat area near the sliding area, the extension direction of the first magnetic strip intersecting 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 the side of the support member away from the middle frame, the support member including 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 attracted to the first magnetic strip; the plurality of second magnetic strips extending along a first direction and spaced apart along a second direction, the second magnetic strips including first magnetic elements and second magnetic elements alternately arranged along the first direction, the first magnetic elements and the second magnetic elements having opposite magnetism, 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 intersecting. By setting a first magnetic strip in the middle frame and a second magnetic strip in the support member facing the middle frame of the display module, the extension direction of the second magnetic strip intersects with that of the first magnetic strip. The second magnetic strip includes a first magnetic element and a second magnetic element with opposite magnetic properties. The second magnetic strip has the same magnetic properties as one of the first and second magnetic elements and the opposite magnetic properties to the other. Based on the attraction between the first and second magnetic strips, precise alignment of the adsorption can be achieved by setting magnetic elements with different magnetic properties, ensuring that the display module remains flat during the sliding process, reducing warping, and thus reducing the risk of display module failure.

[0025] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0027] Figure 1 The image shown is a side view of a display device provided in an embodiment of this disclosure. Figure 2 As shown Figure 1 A partially enlarged schematic diagram, Figure 3 As shown Figure 1 A plan view of the middle support component. Figure 4 As shown Figure 1 A schematic diagram of the arrangement of the first magnetic stripe. Figure 5 The diagram shown illustrates the positional relationship between the first and second magnetic strips according to an embodiment of this disclosure. Please refer to it. Figures 1 to 5 This disclosure provides a display device 100, including: a middle frame 10, the middle frame 10 including a flat area 02 and a sliding area 01, the sliding area 01 being provided with a scroll 13, the middle frame 10 also including a first magnetic strip 11, the first magnetic strip 11 being located on the side of the flat area 02 near the sliding area 01, the extending 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 A partially enlarged schematic diagram of the central region 03 shows that the display device 100 also includes a display module 30 and a support member 20. The display module 30 is fixed to the support member 20 and is located on the side of the support member 20 opposite to the central frame 10. The support member 20 includes a plurality of second magnetic strips 22, which are located in the sliding area 01 and at least partially flat area 02. The second magnetic strips 22 are magnetically attracted to the first magnetic strip 11. It should be noted that... Figures 1 to 5 The number and spacing of the first magnetic strip 11 and the second magnetic strip 22 are for illustrative purposes only, and this disclosure does not limit them. 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 spaced apart along the second direction D2. The second magnetic strips 22 include first magnetic elements 221 and second magnetic elements 222 arranged alternately along the first direction D1. The first magnetic element 221 and the second magnetic element 222 have opposite magnetic properties. 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 and the second direction D2 intersect.

[0029] For details, please refer to Figure 1 In one optional embodiment provided in this disclosure, the display device 100 includes a middle frame 10, which provides support for the display module 30. Optionally, the middle frame 10 can be made of metal, such as an elemental metal or a metal alloy. Alternatively, the middle frame 10 can be made of a non-metallic material with a certain strength, such as an inorganic or organic non-metallic material. This disclosure does not limit the choice of material; 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. Understandably, 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 the choice of material. Figure 1 The illustration only takes the example of the scroll 13 located on one side of the middle frame 10 along the second direction D2. The scroll 13 is used to extend the display module 30 along the second direction D2 or the first direction D1, but this disclosure does not limit it in this respect. Figure 1 The illustration is based solely on the example of the scroll 13 used to extend the display module 30 along the second direction D2.

[0030] Please refer to Figure 4The middle frame 10 also includes a first magnetic strip 11, which is located on the side of the flat area 02 near 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 attraction for the display module 30, which 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 the warping of the display module 30 during sliding and improving the flatness of the display module 30. The extension direction of the first magnetic strip 11 intersects the axial direction of the scroll 13. Optionally, the first magnetic strip 11 extends along the first direction D1, and the axial direction of the scroll 13 is parallel to the second direction D2; or, the first magnetic strip 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 the second direction D2. This disclosure does not limit this, as long as the extension direction of the first magnetic strip 11 intersects the axial direction of the scroll 13. Figure 4 The illustration is based on the example of the first magnetic strip 11 extending along the second direction D2 and the axis of the spool 13 being parallel to the first direction D1.

[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 away from the middle frame 10. The display module 30 is fixedly connected to the support member 20. The display module 30 is attracted to the first magnetic strip 11 on the middle frame 10 through the support member 20 to keep the display module 30 flat during the rolling process. The support member 20 includes a plurality of second magnetic strips 22, which are located in the sliding area 01 and at least part of the flat area 02. Understandably, when the setting range of the second magnetic strips 22 in the support member 20 is greater 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 will be displaced as the display module 30 slides. When any part of the display module 30 slides to the boundary between the sliding area 01 and the flat area 02, the second magnetic strips 22 in the support member 20 on the side of the display module 30 facing the middle frame 10 will be magnetically attracted to 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 boundary between the sliding area 01 and the flat area 02, thereby reducing the risk of failure of the display module 30 due to sliding warping.

[0032] Optionally, there may be a gap between the second magnetic strip 22 and the first magnetic strip 11 or there may be no gap. This disclosure does not limit this, as long as the first magnetic strip 11 and the second magnetic strip 22 can generate magnetic attraction.

[0033] When the first magnetic strip 11 in the middle frame 10 extends along the second direction D2, the second magnetic strip 22 in the support member 20 extends along the first direction D1 and is spaced apart along the second direction D2. The accompanying drawings in the specification only illustrate the example where the second direction D2 is parallel to the extension direction of the first magnetic strip 11. In some other embodiments, the second direction D2 may be parallel to the extension direction of the scroll 13, and the first direction D1 may be parallel to the extension direction of the first magnetic strip 11. This disclosure does not specifically limit the orientation of the first direction D1 and the second direction D2, as long as the extension direction of the first magnetic strip 11 intersects with the extension direction of the second magnetic strip 22, and the arrangement direction of the second magnetic strip 22 is the same as the extension direction of the first magnetic strip 11.

[0034] Please refer to Figure 3 and Figure 5 The second magnetic strip 22 also includes a first magnetic element 221 and a second magnetic element 222 arranged alternately along the first direction D1. The first magnetic element 221 and the second magnetic element 222 have opposite magnetic properties. Understandably, in a direction parallel to the plane of the middle frame 10, multiple first magnetic strips 11 extend along the second direction D2 and are spaced apart along the first direction D1. There is a first gap 111 between adjacent first magnetic strips 11. Optionally, when the first magnetic strip 11 has the opposite magnetic properties to the first magnetic element 221 in the second magnetic strip 22, the first magnetic strip 11 attracts the first magnetic element 221 in the second magnetic strip 22 arranged alternately along the second direction D2. The length of the first gap 111 along the first direction D1 is greater than or equal to the length of the second magnetic element 222 along the first direction D1, allowing the first magnetic strip 11 to attract the first magnetic element 221. The first magnetic strip 11 and the second magnetic element 222 have the same magnetic properties, which allows the first magnetic strip 11 and the adjacent second magnetic element 222 to repel each other due to their similar polarities, thus facilitating precise alignment of the magnetic adsorption. Alternatively, when the first magnetic strip 11 and the second magnetic element 222 in the second magnetic strip 22 have opposite magnetic properties, the first magnetic strip 11 attracts the second magnetic element 222 in the second magnetic strip 22 that are spaced apart along the second direction D2. The length of the first interval 111 along the first direction D1 is greater than or equal to the length of the first magnetic element 221 along the first direction D1, which allows the first magnetic strip 11 and the second magnetic element 222 to attract each other strongly. Since the first magnetic strip 11 and the first magnetic element 221 have the same magnetic properties, the first magnetic strip 11 and the adjacent first magnetic element 221 can repel each other due to their similar polarities, thus facilitating precise alignment of the magnetic adsorption.

[0035] Thus, by setting a first magnetic strip 11 in the middle frame 10 and a second magnetic strip 22 in the support member 20 on the side of the display module 30 facing the middle frame 10, the second magnetic strip 22 intersects the extension direction of the first magnetic strip 11. The second magnetic strip 22 includes a first magnetic element 221 and a second magnetic element 222 with opposite magnetic properties. The second magnetic strip 22 has the same magnetic properties as one of the first magnetic elements 221 and the second magnetic element 222, and the opposite magnetic properties to the other magnetic element. Based on the magnetic attraction between the first magnetic strip 11 and the second magnetic strip 22, precise alignment of adsorption can be achieved by setting magnetic elements with different magnetic properties, ensuring that the display module 30 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 this. Figure 5 This disclosure provides a display device 100 in which a first magnetic strip 11 is attracted to a first magnetic element 221 among a plurality of second magnetic strips 22, or the first magnetic strip 11 is attracted to a second magnetic element 222 among a plurality of second magnetic strips 22, along a direction perpendicular to the plane of the middle frame 10.

[0037] Specifically, in one optional embodiment provided in this disclosure, when the display module 30 is rolled up, the projection of the first magnetic element 221 in the second magnetic strip 22 onto the plane of the middle frame 10 at least partially overlaps with the projection of the first magnetic strip 11 onto the plane of the middle frame 10. The projection of the second magnetic element 222 in the second magnetic strip 22 onto the plane of the middle frame 10 at least partially overlaps with the projection of the first interval 111. The first magnetic element 221 has the opposite magnetism to the first magnetic strip 11, and the second magnetic element 222 has the same magnetism as the first magnetic strip 11. The first magnetic element 221 in the second magnetic strip 22 magnetically attracts the first magnetic strip 11. Since the second magnetic element 222 between two adjacent first magnetic elements 221 along the first direction D1 has the same magnetism 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 the repulsion of like charges, thus reducing adsorption misalignment.

[0038] In another optional embodiment provided in this disclosure, when the display module 30 is rolled up, the second magnetic element 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 element 221 in the second magnetic strip 22 at least partially overlaps with the projection of the first interval 111 on the plane where the middle frame 10 is located. The second magnetic element 222 has the opposite magnetism to the first magnetic strip 11, and the first magnetic element 221 has the same magnetism as the first magnetic strip 11. The second magnetic element 222 in the second magnetic strip 22 magnetically attracts the first magnetic strip 11. Since the first magnetic element 221 between two adjacent second magnetic elements 222 along the first direction D1 has the same magnetism 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 the repulsion of like charges, thus reducing adsorption misalignment.

[0039] Thus, by setting one magnetic element in the second magnetic strip 22 to have the opposite magnetic properties to the first magnetic strip 11 and setting the other magnetic element to have the same magnetic properties as the first magnetic strip 11, the present embodiment can improve the precise alignment of magnetic adsorption while maintaining the flatness of the display module 30 during the sliding process, and reduce defects or failures caused by misalignment.

[0040] Figure 6 As shown Figure 1 Another enlarged partial schematic diagram, specifically, Figure 6 for Figure 1 Please refer to the enlarged view of a portion of the central 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 protrudes at least partially from the support layer 21.

[0041] Specifically, in one optional embodiment provided in this 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 and 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, and the support member 20 includes a second magnetic strip 22. The second magnetic strip 22 and the first magnetic strip 11 are magnetically attracted to each other. The support member 20 also includes a support layer 21, which 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 metallic material or a non-metallic material, which is not limited in this disclosure. 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. The second magnetic strip 22 is fixed to the support layer 21, which facilitates magnetic attraction between the second magnetic strip 22 and the first magnetic strip 11 in the middle frame 10. 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 allows for magnetic attraction between the second magnetic strip 22 and the first magnetic strip 11 in the middle frame 10, while reducing the overall thickness of the display device 100. Thus, by setting the second magnetic strip 22 to at least partially protrude from the support layer 21, the overall thickness of the display device 100 can be reduced by decreasing the height of the second magnetic strip 22 protruding from the support layer 21, while achieving magnetic attraction between the second magnetic strip 22 and the first magnetic strip 11, thereby facilitating the thinning of the display device 100.

[0042] Please continue to refer to this. Figure 1 , Figure 2 and Figure 6This disclosure provides a display device 100, in which a first magnetic strip 11 is embedded inside a middle frame 10, and the side surface of the first magnetic strip 11 facing the support member 20 is on the same plane as the side surface of the middle frame 10 facing the support member 20.

[0043] Specifically, in one optional embodiment provided in this disclosure, the middle frame 10 includes a first magnetic strip 11. The first magnetic strip 11 is located on the side of the flat area 02 near the sliding area 01. Along 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 is on the same plane as the side surface of the middle frame 10 facing the support member 20. That is, the first magnetic strip 11 is embedded inside the middle frame 10 and 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 prone to jamming or obstruction when sliding. By setting the first magnetic strip 11 to not 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 guaranteed based on the magnetic adsorption between the first magnetic strip 11 and the second magnetic strip 22. Thus, by setting the side surface of the first magnetic strip 11 facing the support member 20 to be on the same plane as the side surface of the middle frame 10 facing the support member 20, the smoothness of the display module 30 can be ensured while reducing the stuttering or obstruction during the scrolling process, thereby further improving the smoothness of the scrolling and enhancing the user experience.

[0044] Figure 7 As shown Figure 4 Cross-sectional view along A-A' Figure 8 As shown Figure 1 For another top view of the middle frame, please refer to [reference needed]. Figure 7 and Figure 8 This disclosure provides a display device 100, in which the middle frame 10 includes a slot 12, and a first magnetic strip 11 is located in the slot 12. The slot 12 is used to restrict the first magnetic strip 11 from being dislodged.

[0045] For details, please refer to Figure 7 In one optional embodiment provided in this disclosure, the middle frame 10 includes a slot 12, and the first magnetic strip 11 is located within the slot 12. Optionally, the cross-section of the slot 12 can be a structure similar to that of being narrow at the top and wide at the bottom, used to reduce the first magnetic strip 11 being lifted by magnetic attraction and thus detached from the middle frame 10 by setting a smaller opening. The cross-sectional shape of the slot can be trapezoidal, wedge-shaped, etc. This disclosure does not limit the shape of the slot 12, as long as the slot 12 can restrict the first magnetic strip 11 from detaching. Optionally, please refer to Figure 8The card slot 12 may also include a limiting structure 121. The limiting structure 121 can be, for example, a narrowed portion of the opening of the card slot 12. The limiting structure 121 can press down on the first magnetic strip 11 within the card slot 12, reducing the likelihood of the first magnetic strip 11 being lifted by magnetic attraction and thus detaching from the middle frame 10. This disclosure does not limit the structure or shape of the card slot 12 and the limiting structure 121; it only needs to prevent the first magnetic strip 11 from detaching. Thus, by providing the card slot 12 in the middle frame 10, the first magnetic strip 11 is located within the card slot 12. By reducing the likelihood of the first magnetic strip 11 detaching from the middle frame 10, the reliability of the first magnetic strip 11's attraction is ensured, thereby guaranteeing the stability of the magnetic attraction force.

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

[0047] Specifically, in one optional embodiment provided in this disclosure, the display device 100 includes a mid-frame 10, a support member 20, a display module 30, and a friction-reducing layer 40. The support member 20 is located between the mid-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 mid-frame 10. Optionally, the friction-reducing layer 40 may at least partially cover the mid-frame 10 to reduce friction on the display module 30 during its sliding motion. Optionally, the friction-reducing layer 40 may be a low-friction coefficient material, such as thermoplastic polyester or pressure-sensitive adhesive. The thermoplastic polyester material may be polyethylene terephthalate (PET), 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, for example, by adding slip agents, lubricants, carbon black, etc., which are not limited in this disclosure. The friction-reducing layer 40, made of a low-friction coefficient 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. This allows for adjustment of friction by increasing the distance between the magnetic strips. This disclosure does not limit the thickness of the friction-reducing layer 40; it can be set according to actual needs. Thus, by providing the low-friction coefficient material friction-reducing layer 40 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, reducing the friction between them; on the other hand, the material properties of the friction-reducing layer 40 itself can adjust the friction coefficient of the display module 30 during the sliding process, thereby adjusting the friction and reducing wear on various components.

[0048] Please continue to refer to this. Figure 9 This disclosure provides a display device 100, in which a heat dissipation portion 23 is included between adjacent second magnetic strips 22 along the second direction D2, and the side surface of the heat dissipation portion 23 facing the middle frame 10 is located on the same plane as the side surface of the second magnetic strip 22 facing the middle frame 10.

[0049] Specifically, in one optional embodiment provided in this disclosure, the support member 20 includes a second magnetic strip 22 extending along a first direction D1 and arranged along a second direction D2. The support member 20 also includes a support layer 21. The second magnetic strips 22 at least partially protrude from the support layer 21. A heat dissipation portion 23 is disposed 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 located on the same plane as the surface of the second magnetic strips 22 facing the middle frame 10, that is, the heat dissipation portion 23 is flush with the surface of the second magnetic strips 22 facing the middle frame 10. Optionally, the heat dissipation portion 23 includes a heat dissipation material, which can be a material with heat dissipation function such as silicone. This disclosure does not limit the composition of the heat dissipation material, as long as it has heat dissipation function. Distributing the heat dissipation portion 23 on the side of the display module 30 facing the middle frame 10 can enhance the heat distribution of the display module 30, reduce heat concentration, and ensure display stability. The heat dissipation part 23 is flush with the surface of the second magnetic strip 22 facing the middle frame 10, which can reduce jamming during the scrolling process of the display module 30 while ensuring heat dissipation and improving the smoothness of scrolling. In this way, by setting the heat dissipation part 23 between adjacent second magnetic strips 22 along the second direction D2, the heat dissipation of the display module 30 can be improved, ensuring display stability. Setting the surface of the heat dissipation part 23 facing the middle frame 10 and the surface of the second magnetic strip 22 facing the middle frame 10 to be on the same plane can ensure the smoothness of scrolling of the display module 30, reduce jamming, and improve the user experience.

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

[0051] Specifically, in one optional embodiment provided in this disclosure, the magnetism of the first magnetic strip 11 gradually decreases along the second direction D2, while the magnetism of the second magnetic strips 22 spaced apart along the second direction D2 remains unchanged; or, the magnetism of the first magnetic strip 11 remains unchanged along the second direction D2, while the magnetism of the second magnetic strips 22 spaced apart along the second direction D2 gradually decreases; or, the magnetism of the first magnetic strip 11 gradually decreases along the second direction D2, and the magnetism of the second magnetic strips 22 spaced apart along the second direction D2 also gradually decreases. The decrease in magnetism can be achieved by reducing the area of ​​the magnetic strips or changing the magnetism of the magnetic material, etc., and this disclosure does not limit this. Along the direction from the sliding area 01 to the flat area 02, the magnetic attraction force between the first magnetic strip 11 and the second magnetic strip 22 gradually decreases, which can adjust the attraction and friction between the first magnetic strip 11 and the second magnetic strip 22 in different areas, while ensuring the flatness of the display module 30 during the sliding process. Thus, by setting the magnetic attraction force between the first magnetic strip 11 and the second magnetic strip 22 to gradually decrease along the second direction D2, and setting the attraction and friction forces in different areas between the two to be flexibly adjustable, the flatness of the display module 30 during the sliding process is ensured while unnecessary friction is reduced to reduce wear.

[0052] Figure 10 As shown Figure 4 Cross-sectional view along B-B' Figure 11 The image shown is a top view of another mid-frame provided in an embodiment of this disclosure. Please refer to [the image]. Figures 1 to 11 This 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 one optional embodiment provided in this disclosure, the magnetism of the first magnetic strip 11 gradually decreases along the second direction D2. That is, along the direction from the sliding region 01 to the flat region 02, the magnetism of the first magnetic strip 11 gradually decreases along the second direction D2, thereby reducing the magnetic attraction force between it and the second magnetic strip 22. This adjusts the attraction and friction between different regions of the first magnetic strip 11 and the second magnetic strip 22. Optionally, please refer to... Figure 10 The magnetism of the first magnetic strip 11 can be achieved by reducing its thickness, magnetic energy product, etc., and this disclosure does not limit this. Please refer to... Figure 11In one optional embodiment provided in this disclosure, the width of the first magnetic strip 11 gradually decreases or narrows along the second direction D2. By reducing the width of the first magnetic strip 11 along the second direction D2, the magnetism of the first magnetic strip 11 is gradually reduced, thereby reducing the magnetic attraction force between it and the second magnetic strip 22. This adjusts the attraction and friction between different areas of the first magnetic strip 11 and the second magnetic strip 22. Thus, by reducing the magnetism or width of the first magnetic strip 11 along the second direction D2, the magnetism of the first magnetic strip 11 in the direction from the sliding area 01 to the flat area 02 can be reduced, thereby reducing the magnetic attraction force between the first magnetic strip 11 and the second magnetic strip 22. While ensuring the flatness of the display module 30 during the sliding process, by reducing the magnetic attraction force between the first magnetic strip 11 and the second magnetic strip 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 this disclosure, the electronic device 200 may also be circular, elliptical or any other feasible shape, and this disclosure does not specifically limit it in this regard.

[0056] In summary, the present disclosure provides a display device and an electronic device, comprising: a middle frame, the middle frame including a flat area and a sliding area, the sliding area being provided with a scroll, the middle frame also including a first magnetic strip, the first magnetic strip being located on the side of the flat area near the sliding area, the extension direction of the first magnetic strip intersecting 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 the side of the support member away from the middle frame, the support member including 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 attracted to the first magnetic strip; the plurality of second magnetic strips extending along a first direction and spaced apart along a second direction, the second magnetic strips including first magnetic elements and second magnetic elements alternately arranged along the first direction, the first magnetic elements and the second magnetic elements having opposite magnetic properties, 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 intersecting. By setting a first magnetic strip in the middle frame and a second magnetic strip in the support member facing the middle frame of the display module, the extension direction of the second magnetic strip intersects with that of the first magnetic strip. The second magnetic strip includes a first magnetic element and a second magnetic element with opposite magnetic properties. The second magnetic strip has the same magnetic properties as one of the first and second magnetic elements and the opposite magnetic properties to the other. Based on the attraction between the first and second magnetic strips, precise alignment of the adsorption can be achieved by setting magnetic elements with different magnetic properties, ensuring that the display module remains flat during the sliding process, reducing warping, and thus reducing the risk of display module failure.
