Description

Technical Field

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

[0002] With the development of technology, the appearance (ID) of electronic devices (such as mobile phones and tablets) has gradually evolved from candybar phones to foldable phones. Foldable phones have a large screen when open, fully satisfying consumers' visual experience, and are small in size when folded, making them easy to carry. However, when folded, the curved part of the display screen stretches, which can cause light and shadow and creases, affecting the user experience. Summary of the Invention

[0003] This application provides a display module and an electronic device that can solve the technical problems of light and shadow and creases easily appearing on the display screen of electronic devices in the prior art.

[0004] In a first aspect, this application provides a display module. The display module includes a display screen and a support member. The display screen includes a first curved segment, a second curved segment, and a third curved segment, which are sequentially connected along the width direction of the display screen. The support member includes a first support portion, a second support portion, and an elastic portion, which are sequentially connected along the width direction of the support member.

[0005] The support member is disposed on the back of the display screen and is stacked with the display screen along the thickness direction of the display screen. The first support part is disposed opposite to and fixedly connected to the first curved section, the second support part is disposed opposite to and fixedly connected to the third curved section, and the elastic part is disposed opposite to the second curved section.

[0006] When the display screen bends, the second bending segment bends and stretches toward the elastic part, and the elastic part bends and stretches elastically away from the second bending segment.

[0007] When the display screen is unfolded, the elastic part unfolds and elastically returns to its original position, causing both the first support part and the second support part to move toward the elastic part. The first support part causes the first curved segment to move toward the second curved segment, and the second support part causes the third curved segment to move toward the second curved segment, so that the second curved segment retracts.

[0008] The display module is used in foldable electronic devices. When the electronic device is folded, the display module bends. When the electronic device is unfolded, the display module unfolds. When the display module bends, the display bends, and the second bending segment of the display bends and stretches towards the elastic part, thereby forming a dent in the second bending segment.

[0009] In this embodiment, by providing a support member on the back of the display screen and incorporating an elastic portion within the support member, the elastic portion stretches and elongates when the display module bends. When the display module unfolds, the elastic portion elastically returns to its original position, causing the first bent portion of the display screen to retract inward. This reduces or even eliminates the dents generated when the display screen bends, thereby reducing or even preventing light and shadow creases on the display screen, improving the display effect, and enhancing the user experience. Furthermore, in this embodiment, the elastic restoring force of the elastic portion causes the first bent portion to retract inward, eliminating the dents generated when the display screen is bent. This reduces or even prevents creep caused by continuous stretching of the display screen, thus preventing light and shadow creases from forming on the electronic device after repeated use. This extends the lifespan of the electronic device and the display module, further enhancing the user experience.

[0010] In one possible implementation, the elastic portion includes a plurality of tension ribs and a plurality of support bodies. The plurality of support bodies are located between the first support portion and the second support portion, and are spaced apart along the width direction of the support member. The support body closest to the first support portion is fixedly connected to the first support portion, and the support body closest to the second support portion is fixedly connected to the second support portion. At least one tension rib is connected between every two adjacent support bodies.

[0011] When the elastic part bends, the tension rib stretches elastically, increasing the distance between two adjacent supports; when the elastic part unfolds, the tension rib recovers elastically, decreasing the distance between two adjacent supports and causing both the first support and the second support to move toward the elastic part.

[0012] Understandably, the multiple supports and tension ribs in the elastic section are staggered along the width of the support. When the display screen unfolds, the support provides excellent support, improving the display effect. When the display screen bends, the tension ribs bend and stretch, allowing the bending angle of the elastic section to better match the bending angle of the second bending segment. This prevents the support from squeezing the display screen and extends its lifespan.

[0013] In this embodiment, by setting multiple supports and multiple tension ribs, the deformation of the elastic part during elastic recovery can be increased, thereby increasing the amount of retraction when the elastic part retracts inward to drive the first curved part of the display screen. This further reduces the dents generated when the display screen is bent and further avoids light and shadow creases on the display screen, thus improving the display effect.

[0014] Furthermore, in this embodiment, an elastic tension rib is used to achieve elastic stretching and elastic recovery of the elastic part, so that the elastic part can return to its initial state after being stretched, and the creep of the elastic part during the continuous elastic stretching and elastic recovery process can be reduced. As a result, when the display screen switches from the folded state to the unfolded state multiple times, the elastic part can drive the display screen to return to its initial state through elastic recovery, and the dents formed when the display screen is bent will disappear. This can prevent the electronic device from developing light and shadow creases after repeated use, thereby improving the service life of the electronic device and the display module, and enhancing the user experience.

[0015] In one possible implementation, there are at least four supports and at least three tension ribs; when the elastic part is extended to bend, the elongation of the tension rib located at the center of the width direction of the support is greater than the elongation of the tension ribs on both sides.

[0016] In this embodiment, by setting the elongation of the tension rib at the center of the support member in the width direction to be greater than the elongation of the tension ribs on both sides when the elastic part is unfolded to bend, the length of the tension rib at the center is greater than the length of the tension ribs on both sides when the display screen bends. This allows the elastic part to have a larger bending angle, thereby providing more clearance for bending at the center of the display screen in the width direction and providing more clearance for bending of the entire display screen. This can further avoid squeezing the display screen and improve the display effect and service life of the display screen.

[0017] In one possible implementation, each support includes a connecting rib and a plurality of sub-supports, the sub-supports of each support being spaced apart along the length direction of the support, and at least one connecting rib connecting each pair of adjacent sub-supports. Each tension rib includes a plurality of tension ribs, the tension ribs of each tension rib being spaced apart along the length direction of the support and along the width direction of the support, at least one tension rib connecting each pair of adjacent sub-supports.

[0018] In this embodiment, by setting multiple sub-supports in each support body and connecting the multiple sub-supports to each other by connecting ribs, the support performance of the support body can be guaranteed while increasing the flexibility of the elastic part. This makes it easier for the elastic part to bend when the display screen is bent, and the bending angle of the elastic part can be better matched with the bending angle of the second bending segment. This can further prevent the support from squeezing the display screen and improve the service life of the display screen.

[0019] In one possible implementation, at least one of the supports includes a reinforcing support; the dimension of the reinforcing support along the width direction of the support is greater than the dimension of the sub-support along the width direction of the support.

[0020] In this embodiment, by setting a larger reinforcing support body on the support body, the structural strength of the elastic part can be increased while ensuring that the elastic part has a certain degree of flexibility, thereby improving the support performance of the support member for the display screen.

[0021] In one possible implementation, at least two of the supports include the reinforcing support, and the reinforcing support in at least two of the supports is at least partially offset along the width direction of the support.

[0022] In this embodiment, by partially offsetting multiple reinforcing supports along the width direction of the support member, the reinforcing supports are more evenly distributed in the elastic part, thereby improving the uniformity of the structural strength of the elastic part, avoiding areas with excessively low strength in the elastic part, and further improving the structural strength of the support member and the support performance of the support member for the display screen.

[0023] In one possible implementation, the tension bar is curved and made of an elastic material.

[0024] During stretching, the tension rib gradually changes from a curved shape to a straight shape, or the curvature of the curve gradually decreases, thus elongating the tension rib. Simultaneously, the polymer chains in the elastic material move during stretching, causing the tension rib to elongate. This increases the deformation of the tension rib during stretching, thereby increasing the deformation of the elastic part and providing greater clearance for the bending of the display screen, further preventing pressure on the display screen.

[0025] In one possible implementation, the tension bar is made of an elastic material and has a tension hole. When the tension bar elastically elongates, the size of the tension hole increases along the elastic elongation direction of the tension bar.

[0026] In this embodiment, by providing tension holes on the tension rib made of elastic material, the tension rib elongates not only through the movement of the polymer chains of the elastic material but also through the deformation of the tension holes when it elastically elongates. This increases the deformation of the tension rib, thereby providing more space to avoid bending of the display screen and further preventing compression of the display screen.

[0027] In actual design, the number of tension holes on the tension ribs at different locations can be adjusted according to the required amount of stretching at different positions of the elastic part. The more tension holes on the tension ribs, the greater the stretching amount during tensioning; the fewer tension holes on the tension ribs, the smaller the stretching amount during tensioning.

[0028] In one possible implementation, the tension bar is made of an elastic material and includes a first connecting segment, a second connecting segment, and a tension segment. The first connecting segment and the second connecting segment are located at opposite ends of the tension segment along its length. One end of the first connecting segment is fixedly connected to an adjacent support body, and the other end is connected to the tension segment. Similarly, one end of the second connecting segment is fixedly connected to an adjacent support body, and the other end is connected to the tension segment.

[0029] The dimension of the connecting segment along the length of the support member is smaller than the dimensions of the first connecting segment along the length of the support member and the dimensions of the second connecting segment along the length of the support member. When the tension bar elastically elongates, the tension segment elastically elongates along the width direction of the support member.

[0030] In this embodiment, an elastic material is used to prepare the tension rib, and by setting a tension section with a reduced width in the tension rib, the elastic elongation of the elastic part can be achieved, and the tension of the support can be realized. This simplifies the manufacturing process of the support, thereby simplifying the manufacturing process of the display module and electronic device, and reducing the manufacturing cost of electronic device.

[0031] In practical design, the width of the stretching section of the tension rib at different locations can be adjusted according to the stretching requirements of the elastic part at different locations. The smaller the width of the stretching section of the tension rib, the greater the stretching amount during tensioning; conversely, the larger the width of the stretching section of the tension rib, the smaller the stretching amount during tensioning.

[0032] In one possible implementation, the elastic part includes a connecting shaft that is fixedly connected to the tension bar and the corresponding support.

[0033] The connecting shaft can be a separate structural component, and both the tension rib and the corresponding support body are provided with connecting holes. The connecting shaft passes through the connecting holes of the tension rib and the corresponding support body, and is fixedly connected to the tension rib and the corresponding support body.

[0034] Alternatively, the connecting shaft can be integrally formed with the connecting rib, and the support body corresponding to the tension rib is provided with a connecting hole. The connecting shaft passes through the connecting hole of the support body and is fixedly connected to the support body.

[0035] Alternatively, the connecting shaft can be integrally formed with the support body, and the tension rib corresponding to the support body has a connecting hole. The connecting shaft passes through the connecting hole of the tension rib and is fixedly connected to the tension rib.

[0036] In this embodiment, the support body and the tension rib are fixedly connected by a connecting shaft, allowing the support body and tension rib to be formed separately during the fabrication of the elastic part, and then assembled. This reduces the fabrication difficulty of the elastic part, thereby reducing the manufacturing cost of the support component and the display module. Furthermore, different materials can be used to fabricate the support body and tension rib separately during the manufacturing process, increasing the production flexibility of the elastic part and the support component, further reducing the manufacturing cost of the support component and the display module.

[0037] Secondly, this application provides an electronic device. The electronic device includes a first housing, a second housing, a pivot mechanism, and the aforementioned display module. The display module further includes a first display unit and a second display unit, wherein the first display unit is connected to the side of the first curved section opposite to the second curved section, and the second display unit is connected to the side of the third curved section opposite to the second curved section.

[0038] The hinge mechanism is connected between the first housing and the second housing. The display module is mounted on the first housing, the second housing, and the hinge mechanism. The support member is located between the display screen and the hinge mechanism, and is positioned opposite to the hinge mechanism along the thickness direction of the electronic device. The first display unit is mounted on the first housing, and the second display unit is mounted on the second housing.

[0039] When the rotating shaft mechanism rotates, the first housing and the second housing rotate relative to each other, thereby causing the display screen and the support to bend or unfold.

[0040] When the first and second housings rotate toward each other, they cause the display module to fold, thus bending the display and the support. As the display bends, the second bent section is stretched along its width, creating a dent. As the electronic device gradually rotates from its unfolded state to its folded state, the degree of bending in the second bent section gradually increases, and the dent becomes more pronounced. When the support bends, its elastic portion bends and stretches elastically, providing greater clearance for the display's bending and reducing or even eliminating pressure on the display from the support, thereby preventing damage and extending the display's lifespan.

[0041] When the first and second housings rotate toward each other, they cause the display module to unfold, thereby unfolding the display and the support. When the support unfolds, the elastic part elastically recovers and pulls the first and second support parts toward the elastic part, so that the first support part applies a tensile force toward the second curved section of the display screen to the first curved section, and the second support part applies a tensile force toward the second curved section to the third curved section, squeezing the second curved section inward, thereby causing the second curved section to retract inward and elastically recover, thus making the dent disappear.

[0042] The electronic device provided in this embodiment can eliminate the dents generated when the display screen is bent by setting a support member on the display module. This can prevent the electronic device from developing light and shadow creases after repeated use, thereby improving the service life of the electronic device and enhancing the user experience.

[0043] In one possible implementation, the rotating shaft mechanism includes a base, a first rotating member, and a second rotating member. The first rotating member and the second rotating member are respectively connected to opposite sides of the base in the width direction and are capable of rotating relative to the base.

[0044] The first rotating member is fixedly connected to the first housing and is disposed opposite to and fixedly connected to the first support part along the thickness direction of the electronic device; the second rotating member is fixedly connected to the second housing and is disposed opposite to and fixedly connected to the second support part along the thickness direction of the electronic device; the base and the elastic part are disposed opposite to each other along the thickness direction of the electronic device.

[0045] The first housing rotates relative to the base via a first rotating component, and the second housing rotates relative to the base via a second rotating component. In other words, the first and second housings unfold and fold relative to each other via a pivot mechanism.

[0046] In summary, this application provides a support member on the back of the display screen, with an elastic portion within the support member. When the display module bends, the elastic portion stretches and elongates; when the display module unfolds, the elastic portion returns to its original position, causing the first bent portion of the display screen to retract inwards. This reduces or even eliminates dents caused by bending, thereby reducing or preventing light and shadow creases on the display screen, improving display quality, and enhancing the user experience. Furthermore, the display module provided by this application, through the elastic return force of the elastic portion causing the first bent portion to retract inwards, eliminates dents caused by bending, reducing or even preventing creep during continuous stretching. This prevents light and shadow creases from forming on electronic devices after repeated use, thus extending the lifespan of the electronic device and the display module, and improving the user experience.

Figure 2 This is a schematic diagram of the electronic device 500 provided in the embodiments of this application in a second state. Figure 3 This is a schematic diagram of the structure of the electronic device 500 provided in the embodiments of this application in the third state.

[0077] Electronic device 500 includes, but is not limited to, cellphones, notebook computers, tablet computers, laptop computers, personal digital assistants, wearable devices, or mobile devices. In this embodiment, a cellphone is used as an example for illustration.

[0078] Figure 1 The electronic device 500 shown is in an unfolded state. Figure 2The electronic device 500 shown is in a semi-deployed state. Figure 3 The electronic device 500 shown is in a folded state. Figure 1 The unfolding angle β of the electronic device 500 shown is 180 degrees. Figure 2 The unfolding angle α of the electronic device 500 shown is 90 degrees.

[0079] For ease of description, in this application, the width direction of the electronic device 500 in its unfolded state is defined as the X direction, the length direction as the Y direction, and the thickness direction as the Z direction. The X, Y, and Z directions are all perpendicular to each other.

[0080] It should be noted that slight deviations are allowed in the angles illustrated in the embodiments of this application. For example, Figure 1 The unfolding angle β of the electronic device 500 shown is 180 degrees, which means that β can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. Figure 2 The unfolding angle α of the electronic device 500 shown is 90 degrees, meaning that α can be 90 degrees, or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees, or 0 degrees. The angles illustrated in the following text can be understood in the same way.

[0081] The electronic device 500 shown in this embodiment is an electronic device 500 capable of being folded once. In some other embodiments, the electronic device 500 may also be an electronic device 500 capable of being folded multiple times (more than twice). In this case, the electronic device 500 may include multiple parts, with adjacent parts folded relatively close together until the electronic device 500 is in a folded state, and adjacent parts unfolded relatively far apart until the electronic device 500 is in an unfolded state.

[0082] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 1 An exploded view of the electronic device 500 shown. Figure 5 yes Figure 4 The diagram shows a partially exploded view of the electronic device 500 in the first embodiment.

[0083] Electronic device 500 includes a folding device 200 and a display module 100. The folding device 200 includes a first housing 210, a second housing 220, and a pivot mechanism 300. The pivot mechanism 300 includes a base 310, a first rotating member 320, and a second rotating member 330. The first rotating member 320 and the second rotating member 330 are respectively connected to opposite sides of the base 310 in the width direction and are rotatably connected to the base 310. The pivot mechanism 300 is disposed between the first housing 210 and the second housing 220, with the first rotating member 320 fixedly connected to the first housing 210 and the second rotating member 330 fixedly connected to the second housing 220. When the first housing 210 rotates relative to the base 310, it drives the first rotating member 320 to rotate relative to the base 310. When the second housing 220 rotates relative to the base 310, it drives the second rotating member 330 to rotate relative to the base 310, thereby realizing the rotational connection between the first housing 210 and the second housing 220, and enabling the electronic device 500 to switch between an unfolded state and a folded state. The rotation direction of the first housing 210 is opposite to that of the second housing 220, and the rotation direction of the first rotating member 320 is opposite to that of the second rotating member 330.

[0084] The display module 100 includes a display screen 20 and a support member 10. The display screen 20 includes a display surface 201 and a mounting surface 202. The display surface 201 and the mounting surface 202 are disposed opposite to each other along the thickness direction of the display screen 20. The display surface 201 is used to display text, images, and videos, etc. The display screen 20 includes a first display portion 22, a second display portion 23, and a first curved portion 21. The first curved portion 21 is located between the first display portion 22 and the second display portion 23, and the first curved portion 21 can be bent. The first display portion 22, the second display portion 23, and the first curved portion 21 together constitute the display screen 20. In this embodiment, the display screen 20 is a flexible display screen 20, such as an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen.

[0085] The support member 10 includes a first surface 101 and a second surface 102. The first surface 101 and the second surface 102 are disposed opposite to each other along the thickness direction of the support member 10. The support member 10 also includes a first support portion 11, a second support portion 12, and a second curved portion 103. The second curved portion 103 is connected between the first support portion 11 and the second support portion 12. The second curved portion 103 includes a plurality of sub-connecting portions 104. The plurality of sub-connecting portions 104 are connected sequentially along the X direction. Specifically, the edges of the plurality of sub-connecting portions 104 are connected during integral molding. A hollow portion 105 is provided between every two adjacent sub-connecting portions 104. The hollow portion 105 penetrates the second surface 102.

[0086] The support member 10 and the first curved portion 21 of the display screen 20 are stacked along the Z direction and arranged opposite to each other, with the first surface 101 facing the mounting surface 202. The display screen module 100 is mounted on the folding device 200, with the first display portion 22 arranged opposite to and fixedly connected to the first housing 210, and the second display portion 23 arranged opposite to and fixedly connected to the second housing 220. The first curved portion 21 is arranged opposite to the pivot mechanism 300. The support member 10 is disposed between the display screen 20 and the folding device 200, with the second surface 102 facing the folding device 200, and the support member 10 is arranged opposite to the pivot mechanism 300. In this embodiment, the support member 10 is fixedly connected to the display screen 20. Exemplarily, the support member 10 is bonded to the mounting surface 202 of the display screen 20. In other embodiments, the support member 10 may also be fixedly connected to the pivot mechanism 300. For example, the first support portion 11 is fixedly connected to the first rotating member 320, the second support portion 12 is fixedly connected to the second rotating member 330, and the second curved portion 103 is disposed opposite to the base 310.

[0087] In this embodiment, the area of ​​the support member 10 is the same as or approximately the same as the area of ​​the first curved portion 21. The orthographic projection of the support member 10 along the Z direction coincides with or approximately coincides with the orthographic projection of the first curved portion 21 along the Z direction. That is, the support member 10 and the rotating shaft mechanism 300 are arranged opposite each other along the Z direction, and the orthographic projection of the support member 10 along the Z direction coincides with or approximately coincides with the orthographic projection of the rotating shaft mechanism 300 along the Z direction.

[0088] In other embodiments, the area of ​​the support member 10 may also be larger than the area of ​​the first curved portion 21. For example, the support member 10 may also be attached to the entire back of the display screen 20, that is, the orthographic projection of the support member 10 along the Z direction coincides with or substantially coincides with the orthographic projection of the display screen 20 along the Z direction. Alternatively, the orthographic projection of the support member 10 along the Z direction covers the first curved portion 21 and partially covers the first display portion 22 and the second display portion 23.

[0089] Combination Figure 1The first housing 210 and the second housing 220 rotate in a relatively distant direction, causing the first rotating member 320 and the second rotating member 330 to rotate in a relatively distant direction, and causing the display module 100 to unfold, so that the electronic device 500 can unfold. When the electronic device is in the unfolded state, the included angle between the first housing 210 and the second housing 220 is β. The first curved portion 21 of the display 20 and the second curved portion 103 of the support member 10 are both unfolded. The first display portion 22 and the second display portion 23 are unfolded relative to each other, and the first support portion 11 and the second support portion 12 are unfolded relative to each other. At this time, the included angle between the first display portion 22, the second display portion 23 and the first curved portion 21 is β. The display 20 has a large display area, thereby realizing a large-screen display of the electronic device 500 and improving the user experience. The included angle between the first support portion 11, the second support portion 12, and the second curved portion 103 is β. The sub-connecting portions 104 are arranged side by side along the X direction and the interval between them is small. That is, the size of the hollow portion 105 is small. The support member 10 supports the display screen 20 and can improve the display effect of the display screen 20.

[0090] Please combine Figure 2 , Figure 4 and Figure 5 The first housing 210 and the second housing 220 rotate toward each other, causing the first rotating member 320 and the second rotating member 330 to rotate toward each other, and causing the display module 100 to fold, so that the electronic device 500 is in a semi-open state. Specifically, when the first housing 210 and the second housing 220 rotate toward each other, the first display part 22 and the second display part 23 of the display screen 20 rotate toward each other, and the first curved part 21 bends, thereby causing the first curved part 21 to drive the first support part 11 and the second support part 12 of the support member 10 to rotate toward each other, which in turn causes the second curved part 103 to bend, and increases the gap between two adjacent sub-connecting parts 104, that is, increases the size of the cutout part 105. When the electronic device 500 is in the semi-open state, the included angle between the first display part 22 and the second display part 23 is α.

[0091] Please combine Figures 3 to 6 , Figure 6 yes Figure 5 A schematic diagram of the support member 10 in another state in the electronic device 500 shown.

[0092] The first housing 210 and the second housing 220 rotate further toward each other, causing the first rotating member 320 and the second rotating member 330 to rotate further toward each other, and causing the display module 100 to fold further until the electronic device 500 is in a folded state. When the first housing 210 and the second housing 220 rotate further toward each other, the first display part 22 and the second display part 23 rotate further toward each other, and the first bent part 21 bends further, so that the first bent part 21 drives the first support part 11 and the second support part 12 of the support member 10 to rotate further toward each other, thereby causing the second bent part 103 to bend further, and the gap between the two adjacent sub-connecting parts 104 to increase further, that is, to increase the size of the hollow part 105.

[0093] like Figure 3 As shown, when the electronic device 500 is in a folded state, the first curved portion 21 of the display screen 20 bends, and the first display portion 22 and the second display portion 23 are positioned opposite each other. At this time, the display screen 20 is located between the first housing 210 and the second housing 220, which greatly reduces the probability of the display screen 20 being damaged and achieves effective protection for the display screen 20.

[0094] like Figure 6 As shown, when the electronic device 500 is in a folded state, the first support portion 11 and the second support portion 12 are folded relative to each other, and the second curved portion 103 is in a curved state, bending away from the display screen 20. This provides clearance for the first curved portion 21 of the display screen 20, allowing it to have greater bending space when the electronic device 500 is folded. This reduces or even eliminates pressure from the support member 10 on the display screen 20, thereby reducing creases in the display screen 20 and extending its lifespan.

[0095] At the same time, when the second bending portion 103 bends, the gap between the two adjacent sub-connecting portions 104 increases, that is, the size of the hollow portion 105 increases, thereby increasing the bending angle of the second bending portion 103, which in turn provides more clearance space for the display screen 20, further reducing or even avoiding the pressure of the support member 10 on the display screen 20.

[0096] Please see Figure 7 , Figure 7 yes Figure 5 A schematic diagram of the display module 100 in the electronic device 500 being in a stretched state.

[0097] When the display module 100 is subjected to tensile forces on opposite sides in the width direction (X direction) of the display module 100, the display 20 is stretched in the width direction, thereby forming a recess 1 in the first curved portion 21. At the same time, the display 20 causes the second curved portion 103 of the support member 10 to be stretched, and the size of the cutout portion 105 increases.

[0098] Please combine Figures 1 to 3 When the electronic device 500 rotates from the unfolded state to the folded state, the first housing 210 and the second housing 220 rotate toward each other, causing the first display unit 22 and the second display unit 23 to rotate toward each other, thereby causing the first curved portion 21 to bend. When the first curved portion 21 bends, the display module 100 is in a stretched state. At this time, when the first curved portion 21 bends, the display screen 20 is stretched in the width direction, thereby forming a dent 1 in the first curved portion 21. Simultaneously, the display screen 20 causes the second curved portion 103 of the support member 10 to bend, and the size of the cutout portion 105 increases.

[0099] When the angle between the first housing 210 and the second housing 220 is greater than or equal to 0 degrees and less than 180 degrees, the display module 100 is in a stretched state.

[0100] When the electronic device 500 rotates from a folded state to an unfolded state, the first housing 210 and the second housing 220 rotate in a direction away from each other, causing the first display unit 22 and the second display unit 23 to rotate in a direction away from each other, thereby unfolding the first curved portion 21, simultaneously unfolding the support member 10, and unfolding the second curved portion 103. When the second curved portion 103 unfolds, the size of the cutout portion 105 decreases.

[0101] As the electronic device 500 continuously switches between a folded and unfolded state, the first curved portion 21 of the display screen 20 continuously bends and unfolds, and is constantly stretched. This causes the creep phenomenon of the first curved portion 21 to become increasingly obvious, making it impossible for the first curved portion 21 to return to its initial state. That is, when the electronic device 500 is in the unfolded state, the size of the first curved portion 21 along the X direction increases. As a result, when the electronic device 500 rotates to the unfolded state, the display screen 20 cannot return to its initial state, meaning that the indentation 1 formed on the display screen 20 in the folded state cannot be completely eliminated. This causes the light and shadow creases on the display screen 20 to become increasingly obvious, which in turn affects the display effect of the display screen 20 and the user experience.

[0102] Please see Figures 8 to 10 , Figure 8 yes Figure 4 The diagram shows a partial structural representation of the electronic device 500 in the second embodiment. Figure 9 yes Figure 8 A schematic diagram of the structure of the support member 10 in the electronic device 500 is shown. Figure 10 yes Figure 9 A partial structural diagram of the support member 10 shown at another angle.

[0103] This embodiment and Figure 5 The difference in the illustrated embodiment is that, in this embodiment, the support member 10 includes a first support portion 11, a second support portion 12, and an elastic portion 13. The elastic portion 13 is connected between the first support portion 11 and the second support portion 12. The elastic portion 13 is elastic and capable of elastic elongation and elastic recovery. The support member 10 has an unfolded state and a bent state. When the support member 10 is in the unfolded state, the elastic portion 13 is in a pre-stretched state. When the support member 10 is in the bent state, the elastic portion 13 elastically elongates and is in a stretched state. When the support member 10 switches from the bent state to the unfolded state, the elastic recovery force of the elastic portion 13 causes it to switch back to the pre-stretched state. When the elastic portion 13 is in the pre-stretched state, it can be in a natural state. Alternatively, when the elastic portion 13 is in the pre-stretched state, it can also be compressed and have a certain rebound force. This rebound force ensures that the first support portion 11 and the second support portion 12 remain in a relatively unfolded state, that is, that the support member 10 remains in the unfolded state. When the elastic part 13 is in a pre-stretched state and subjected to a tensile force, it can elastically elongate.

[0104] The elastic part 13 includes a support body 14 and a tension rib 15. There are multiple support bodies 14. The multiple support bodies 14 are spaced apart along the X direction, and at least one tension rib 15 is provided between every two adjacent support bodies 14. The tension rib 15 is elastic. The elastic part 13 achieves elastic elongation or elastic recovery through the elastic deformation of the tension rib 15, that is, it can maintain the elastic part 13 in a stretched or pre-stretched state.

[0105] The tension rib 15 is made of an elastic material, while the support 14 is made of a rigid material. A rigid material is one that exhibits good resistance to deformation under static load. Rigid materials deform very little or negligibly under external force. Specifically, the support 14 can be made of plastic, metal, or other materials with high rigidity. In this embodiment, by simultaneously providing the tension rib 15 made of elastic material and the support 14 made of rigid material in the elastic part 13, the elastic part 13 can bend and deform while also providing support for the display screen 20.

[0106] In this embodiment, there are four support bodies 14. The four support bodies 14 are spaced apart along the X-axis. Along the positive X-axis, the four support bodies 14 are respectively a first support body 141, a second support body 142, a third support body 143, and a fourth support body 144. The first support body 141 is connected to the first support portion 11. Specifically, the first support body 141 and the first support portion 11 can be integrally formed, or they can be connected by a pin, or by welding, bonding, or other methods. The fourth support body 144 is connected to the second support portion 12. The connection between the second support body 142 and the third support body 144 is located between the first support body 141 and the fourth support body 144.

[0107] In other embodiments, the support 14 may be two, three, or more than five. No specific limit is placed on the number of support 14 here.

[0108] like Figure 10 As shown, each support body 14 includes multiple sub-support bodies 145. The multiple sub-support bodies 145 of each support body 14 are arranged sequentially at intervals along the Y direction. The multiple sub-support bodies 145 of the multiple support bodies 14 form a mesh structure. Specifically, the first sub-support body of the first support body 141, the first sub-support body of the second support body 142, the first sub-support body of the third support body 143, and the first sub-support body of the fourth support body 144 are arranged side-by-side and at intervals along the X direction. The second sub-support body of the first support body 141, the second sub-support body of the second support body 142, the second sub-support body of the third support body 143, and the second sub-support body of the fourth support body 144 are arranged side-by-side and at intervals along the X direction. Where N is the number of sub-supports 145 in each support 14, and N is a positive integer greater than or equal to 2.

[0109] Along the Y direction, a connecting rib 146 connects every two adjacent sub-supports 145. The connecting rib 146 connects the multiple sub-supports 145 of each support 14 to each other to increase the strength of the elastic part 13, thereby increasing the strength of the support member 10.

[0110] The connecting rib 146 can be made of the same material as or different from the sub-support 145. When the connecting rib 146 and the sub-support 145 are made of the same material, they can be integrally molded. When the connecting rib 146 and the sub-support 145 are made of different materials, they can be fixedly connected by means of pin connection, bonding, welding, or other methods.

[0111] In this embodiment, the width of the connecting rib 146 is smaller than the width of the sub-support 145. That is, the dimension of the connecting rib 146 along the X direction is smaller than the dimension of the sub-support 145 along the X direction. It can be understood that when the material of the connecting rib 146 is the same as that of the sub-support 145, by setting the width of the connecting rib 146 to be smaller than the width of the sub-support 145, the rigidity of the support 14 can be reduced, thereby improving the elastic deformation performance of the elastic part 13 while ensuring the supporting performance of the elastic part 13.

[0112] Please continue reading. Figure 10 In this embodiment, there are three tension ribs 15. Along the positive X-axis, the three tension ribs 15 are designated as a first tension rib 151, a second tension rib 152, and a third tension rib 153. The first tension rib 151 connects the first support body 141 and the second support body 142, the second tension rib 152 connects the second support body 142 and the third tension rib 153, and the third tension rib 153 connects the third support body 143 and the fourth support body 144. In other embodiments, there may be one, two, or more tension ribs 15. The number of tension ribs 15 is not specifically limited here, as long as there is a tension rib 15 between every two adjacent support bodies 14. It is understood that the number of tension ribs 15 is one less than the number of support bodies 14.

[0113] In this embodiment, each tension rib 15 includes multiple sub-tension ribs 154. Along the X direction, a sub-tension rib 154 is provided between every two adjacent sub-supports 145. Specifically, the first sub-tension rib of the first tension rib 151 is connected between the first sub-support of the first support 141 and the first sub-support of the second support 142. The second sub-tension rib of the first tension rib 151 is connected between the second sub-support of the first support 141 and the second sub-support of the second support 142. The Nth sub-tension rib of the first tension rib 151 is connected between the Nth sub-support of the first support 141 and the Nth sub-support of the second support 142. The first sub-tension rib of the second tension rib 152 is connected between the first sub-support of the second support 142 and the first sub-support of the third support 143. The Nth sub-tension rib of the second tension rib 152 is connected between the Nth sub-support of the second support 142 and the Nth sub-support of the third support 143. The first sub-tension bar in the third tension bar 153 is connected between the first sub-support of the third support 143 and the first sub-support of the fourth support 144. The Nth sub-tension bar in the third tension bar 153 is connected between the Nth sub-support of the third support 143 and the Nth sub-support of the fourth support 144.

[0114] In this embodiment, the tension rib 15 is made of an elastomer and is curved. Specifically, the tension rib 15 is S-shaped. In other embodiments, the tension rib 15 can be made of rubber, plastic, or other elastic materials. When the tension rib 15 is made of an elastic material, it can be straight. In this case, when subjected to tensile force, the tension rib 15 achieves elastic elongation through the movement of polymer chains in the elastic material. Alternatively, the tension rib 15 can also be made of rigid materials such as plastic or metal. In this case, the tension rib 15 needs to be made into a shape that can be elastically produced and elastically recovered, such as an S-shape, a snake shape, or a spiral shape. When subjected to tensile force, the tension rib 15 can achieve elastic elongation by changing its shape. In this embodiment, the material of the tension rib 15 is not specifically limited, as long as the tension rib 15 can elastically elongate and elastically recover.

[0115] The material of the tension rib 15 can be the same as or different from the material of the support 14. For example... Figure 10 As shown, when the material of the tension rib 15 is the same as that of the support body 14, the tension rib 15 and the support body 14 can be integrally molded to improve the connection stability between the tension rib 15 and the support body 14, thereby improving the structural stability of the elastic part 13 and the support member 10.

[0116] like Figure 11 As shown, when the material of the tension rib 15 is different from that of the support body 14, the tension rib 15 and the support body 14 can be fixedly connected through shaft holes. For example, each sub-tension rib 154 includes two connecting shafts 1541. The two connecting shafts 1541 are respectively located at opposite ends of the extension direction of the sub-tension rib 154. Each sub-support body 145 is provided with connecting holes 1451 corresponding to the connecting shafts 1541. The sub-tension rib 154 is located between two adjacent sub-support bodies 145, and the two connecting shafts 1541 are respectively located in the connecting holes 1451 of the corresponding two sub-support bodies 145, and are fixedly connected to the corresponding sub-support bodies 145, thereby achieving a fixed connection between the sub-tension rib 154 and the corresponding sub-support body 145. Of course, when the material of the tension rib 15 is the same as that of the support body 14, the tension rib 15 and the support body 14 can also be fixedly connected through shaft holes as shown in the example. Figure 11 As shown, a fixed connection is achieved by setting a connecting shaft 1541 in the tension bar 15 and a connecting hole 1451 in the support body 14.

[0117] In this embodiment, by providing a connecting shaft 1541 in the tension rib 15 and a connecting hole 1451 in the support body 14, a fixed connection between the tension rib 15 and the support body 14 can be achieved. This allows the support body 14 and the tension rib 15 to be formed separately during the fabrication of the elastic part 13, and then assembled. This reduces the fabrication difficulty of the elastic part 13, thereby reducing the manufacturing cost of the support member 10 and the display module 100. Furthermore, different materials can be used to fabricate the support body 14 and the tension rib 15, increasing the production flexibility of the elastic part 13 and the support member 10, and further reducing the manufacturing cost of the support member 10 and the display module 100.

[0118] In one embodiment, the connecting shaft can be a separate structural component, and both the tension rib 15 and the corresponding support body 14 are provided with connecting holes. The connecting shaft passes through the connecting holes of the tension rib 15 and the corresponding support body 14, and is fixedly connected to the tension rib 15 and the corresponding support body 14, thereby realizing the fixed connection between the tension rib 15 and the support body 14.

[0119] Alternatively, the connecting shaft can be integrally formed with the support body 14. That is, the support body 14 is provided with a connecting shaft. The tension rib 15 corresponding to the support body 14 is provided with a connecting hole, and the connecting shaft passes through the connecting hole of the tension rib 15 and is fixedly connected to the tension rib 15, thereby realizing the fixed connection between the tension rib 15 and the support body 14.

[0120] It is understandable that, such as Figure 10 As shown, the elastic part 13 provided in this embodiment is in the form of a grid. The sub-supports 145 can be considered as grid points, and the connecting ribs 146 and tension ribs 15 can be considered as grid lines. Multiple connecting ribs 146 connect multiple sub-supports 145 sequentially along the Y direction, and multiple tension ribs 15 connect multiple sub-supports 145 sequentially along the X direction. This increases the strength of the elastic part 13, thereby increasing the strength of the support member 10 and the display module 100.

[0121] Figure 10 The support 14, tension rib 15, and connecting rib 146 shown can be understood as a set of elastic structures. The elastic part 13 may include one or more sets of elastic structures. When the elastic part 13 includes multiple sets of elastic structures, the multiple sets of elastic structures are stacked along the thickness direction of the support 10. For example, as... Figure 9As shown, the elastic part 13 includes two sets of elastic structures. The two elastic structures are stacked along the thickness direction of the support member 10. The first support body 14 in both sets of elastic structures is fixedly connected to the first support part 11, and the fourth support body 14 in both sets of elastic structures is fixedly connected to the second support part 12. In this embodiment, multiple sets of elastic structures are stacked to form the elastic part 13, which can improve the elastic deformation performance of the elastic part 13 while ensuring its support performance.

[0122] It should be noted that, Figure 9 Only a portion of the structure of the support member 10 along the Y direction is shown. In reality, the support member 10 can consist of multiple... Figure 9 The repeating units shown are connected sequentially along the Y direction to form the structure.

[0123] Please combine Figure 8 and Figure 12 , Figure 12 yes Figure 8 A partial structural schematic diagram of the electronic device 500 shown.

[0124] The first curved portion 21 of the display screen 20 includes a first curved segment 211, a second curved segment 212, and a third curved segment 213. The first curved segment 211, the second curved segment 212, and the third curved segment 213 are connected sequentially along the width direction of the display screen 20. The side of the first curved segment 211 facing away from the second curved segment 212 is connected to the first display unit 22, and the side of the third curved segment 213 facing away from the second curved segment 212 is connected to the second display unit 23.

[0125] A support member 10 is disposed between the display screen 20 and the rotating shaft mechanism 300. Along the thickness direction of the display screen 20, the support member 10 is positioned opposite to the first curved portion 21. In this embodiment, the support member 10 is fixedly connected to the display screen 20. Specifically, the first support portion 11 is positioned opposite to and fixedly connected to the first curved segment 211, the second support portion 12 is positioned opposite to and fixedly connected to the third curved segment 213, and the elastic portion 13 is positioned opposite to the second curved segment 212. In other embodiments, the support member 10 may also be fixedly connected to the rotating shaft mechanism 300. Specifically, the first support portion 11 is fixedly connected to the first rotating member 320, the second support portion 12 is fixedly connected to the second rotating portion, and the elastic portion 13 is positioned opposite to the base 310.

[0126] It should be noted that, in this embodiment, the display module 100 includes a Figure 9 The support member 10 is shown. In other embodiments, the display module 100 may also include multiple such supports. Figure 9 The support member 10 shown is arranged in multiple layers along the Z direction and is located between the display screen 20 and the rotating shaft mechanism 300.

[0127] Combination Figure 1When the electronic device 500 is in the unfolded state, the display module 100 is also unfolded, the display screen 20 is unfolded, the first display section 22 and the second display section 23 are unfolded relative to each other, and the first curved section 21 is flattened. The support member 10 is also unfolded, the first support section 11 and the second support section 12 are unfolded relative to each other, and the elastic section 13 is flattened. Simultaneously, the support member 10 is unfolded, the elastic section 13 is in a pre-stretched state, multiple support bodies 14 are arranged side-by-side along the X direction, and the tension ribs 15 are in a pre-stretched state. At this time, the support member 10 can support the display screen 20, improving the display effect of the display screen 20.

[0128] like Figure 10 and Figure 12 As shown, in this embodiment, the elastic part 13 is in a pre-stretched state, and each tension rib 15 is also in a pre-stretched state. The dimensions of each tension rib 15 along the width direction of the support member 10 are the same, and the degree of bending of each tension rib 15 is also the same. Simultaneously, when the elastic part 13 is in a stretched state, each tension rib 15 is in a pre-stretched state, and the dimensions of each tension rib 15 along the width direction of the support member 10 are the same. That is, when the elastic part 13 is stretched from the pre-stretched state to the stretched state, the elongation of each tension rib 15 is consistent. This simplifies the manufacturing process of the support member 10.

[0129] In other embodiments, when the elastic part 13 is stretched from the pre-stretched state to the stretched state, the elongation of the plurality of tension ribs 15 may be exactly the same or partially the same.

[0130] Please see Figure 13 , Figure 13 yes Figure 12 The diagram shows the structure of the display module 100 in a stretched state.

[0131] When the display module 100 is subjected to tensile forces on opposite sides in the width direction (X direction) of the display module 100, the display screen 20 is stretched in the width direction, thereby forming a dent 1 in the second bending section 212. Simultaneously, the tension rib 15 is stretched along the width direction of the support member 10 and is in a stretched state. At this time, the tension rib 15 becomes longer, that is, the dimension of the tension rib 15 along the width direction of the support member 10 increases. At the same time, the distance between two adjacent supports 14 increases, and the dimension of the elastic part 13 along the width direction of the support member 10 increases.

[0132] Please combine Figures 14 to 16 , Figure 14 yes Figure 8 The diagram shows a simplified structure of the electronic device 500 in a folded state. Figure 15 yes Figure 14 A partial structural schematic diagram of the display module 100 in the electronic device 500 shown. Figure 16 yes Figure 13 A partial structural diagram of the support member 10 in the display module 100 shown.

[0133] When the first housing 210 and the second housing 220 rotate toward each other, they cause the first rotating member 320 and the second rotating member 330 to rotate toward each other, and cause the display module 100 to fold, so that the electronic device 500 is in a folded state. Specifically, when the first housing 210 and the second housing 220 rotate toward each other, they cause the first display section 22 and the second display section 23 of the display screen 20 to rotate toward each other, and cause the first curved section 21 to bend. When the first curved section 21 bends, the first curved segment 211 and the third curved segment 213 rotate toward each other, and the second curved segment 212 bends toward the base 310.

[0134] When the second bending segment 212 bends towards the base 310, it is stretched in the width direction of the display screen 20. At this time, the display screen module 100 is in a stretched state. It can be understood that the display screen module 100 is in a stretched state when it bends. That is, the display screen module 100 is in a stretched state when the angle between the first housing 210 and the second housing 220 is greater than or equal to 0 degrees and less than 180 degrees.

[0135] Combination Figure 13 When the display module 100 is bent, the second bending segment 212 is bent and in a stretched state, which will form a dent 1 in the second bending segment 212. As the electronic device 500 gradually rotates from the unfolded state to the folded state, the degree of bending of the second bending segment 212 gradually increases, and the dent 1 becomes more and more obvious.

[0136] Combination Figure 13 and Figure 15When the electronic device 500 rotates from the unfolded state to the folded state, the first bending segment 211 also drives the first support portion 11 of the support member 10 to rotate towards the second support portion 12, and the third bending segment 213 drives the second support portion 12 to rotate towards the first support portion 11. That is, the first support portion 11 and the second support portion 12 rotate towards each other, thereby driving the elastic portion 13 to bend towards the base 310, and putting the support member 10 in a bent state. When the support member 10 is in a bent state, the elastic portion 13 is in a stretched state, and the tension rib 15 is stretched along the width direction of the support member 10 and is in a stretched state. At this time, the tension rib 15 becomes longer, that is, the dimension of the tension rib 15 along the width direction of the support member 10 increases. At the same time, the distance between two adjacent support bodies 14 increases, and the dimension of the elastic portion 13 along the width direction of the support member 10 increases. Specifically, the first tension rib 151, the second tension rib 152, and the third tension rib 153 are all in a stretched state and are all elongated. The distance between the first support body 141 and the second support body 142, the distance between the second support body 142 and the third support body 143, and the distance between the third support body 143 and the fourth support body 144 are all increased.

[0137] In this embodiment, by providing an elastic part 13 in the support member 10, and when the display module 100 is folded, the tension rib 15 in the elastic part 13 is stretched and lengthened, which can increase the bending angle of the elastic part 13, thereby providing more clearance space for the bending of the display 20, and reducing or even avoiding the support member 10 from squeezing the display 20, thereby avoiding damage to the display 20 and extending the service life of the display 20.

[0138] It should be noted that this embodiment is illustrated using the example of the display module 100 being in a stretched state and the electronic device 500 being in a folded state. In other embodiments, the electronic device 500 may also be in a semi-expanded state when the display module 100 is in a stretched state, as long as the angle between the first housing 210 and the second housing 220 is greater than 0 degrees and less than 180 degrees.

[0139] Please combine Figure 1 , Figure 3 , Figure 12 and Figure 13When the electronic device 500 rotates from a folded state to an unfolded state, the first housing 210 and the second housing 220 rotate in a direction away from each other, causing the first display unit 22 and the second display unit 23 to rotate in a direction away from each other, thereby unfolding the first curved section 21. When the first curved section 21 unfolds, the first curved section 211 causes the first support section 11 to rotate in a direction away from the second support section 12, and the third curved section 213 causes the second support section 12 to rotate in a direction away from the first support section 11, thereby unfolding the first support section 11 and the second support section 12 relative to each other, and unfolding the elastic section 13. At this time, the tension rib 15 of the elastic section 13 elastically returns to the pre-stretched state. At the same time, the tension rib 15 applies a force in the direction of the tension rib 15 to the support bodies 14 on opposite sides connected to the tension rib 15, reducing the distance between the two adjacent support bodies 14, thereby causing the elastic section 13 to return to the pre-stretched state, and causing the support member 10 to return to the unfolded state (e.g., Figure 12 (As shown). Specifically, the second tension rib 152 elastically recovers, causing the second support 142 and the third support 143 to move closer to each other, thus reducing the distance between them. The first tension rib 151 elastically recovers, causing the first support 141 and the second support 142 to move closer to each other, thus reducing the distance between them. The third tension rib 153 elastically recovers, causing the fourth support 144 and the third support 143 to move closer to each other, thus reducing the distance between them.

[0140] When the elastic portion 13 returns from the stretched state to the pre-stretched state, both the first support portion 11 and the second support portion 12 are subjected to a tensile force toward the elastic portion 13. When the first support portion 11 is subjected to a tensile force toward the elastic portion 13, it applies a tensile force toward the second curved portion 212 to the first curved segment 211 of the display screen 20. When the second support portion 12 is subjected to a tensile force toward the elastic portion 13, it applies a tensile force toward the second curved portion 103 to the third curved portion. At this time, the first curved segment 211 and the third curved segment 213 simultaneously compress the second curved portion 103 inward, causing the second curved portion 103 to retract inward and elastically recover, thereby eliminating the indentation 1 on the second curved portion 103.

[0141] In this embodiment, by providing a support member 10 on the back of the display screen 20 and an elastic part 13 on the support member 10, when the display module 100 is folded, the tension rib 15 in the elastic part 13 is stretched and lengthened. When the display module 100 rotates from the folded state to the unfolded state, the elastic part 13 elastically recovers, causing the first bent part 21 of the display screen 20 to retract inward. This reduces or even eliminates the dent 1 generated when the display screen 20 is bent, thereby reducing or even preventing light and shadow creases from appearing on the display screen 20, improving the display effect of the display screen 20, and enhancing the user experience. Furthermore, in this embodiment, the elastic recovery force of the elastic part 13 causes the first bent part 21 to retract inward, eliminating the dent 1 generated when the display screen 20 is bent. This reduces or even prevents creep generated during continuous stretching of the display screen 20, thereby preventing light and shadow creases from appearing on the electronic device 500 after repeated use. This extends the service life of the electronic device 500 and the display module 100, and enhances the user experience.

[0142] Meanwhile, in this embodiment, an elastic tension rib 15 is used to achieve elastic stretching and elastic recovery of the elastic part 13, so that the elastic part 13 can return to its initial state after being stretched, and the creep of the elastic part 13 during the continuous elastic stretching and elastic recovery process can be reduced. As a result, when the display screen 20 switches from the folded state to the unfolded state multiple times, the elastic part 13 can drive the display screen 20 to return to its initial state through elastic recovery, and the indentation 1 formed when the display screen 20 is in the folded state will disappear. This can prevent the electronic device 500 from developing light and shadow creases after multiple uses, thereby improving the service life of the electronic device 500 and the display module 100, and enhancing the user experience.

[0143] Furthermore, in this embodiment, by providing multiple tension ribs 15 and multiple support bodies 14 in the elastic part 13, when the display screen 20 bends, the multiple tension ribs 15 bend and stretch respectively, so that the bending angle of the elastic part 13 can be more adapted to the bending angle of the second bending segment of the display screen 20, thereby avoiding the support member 10 from squeezing the display screen and improving the service life of the display screen 20.

[0144] Furthermore, in this embodiment, by providing multiple sub-supports 145 in each support 14 and connecting the multiple sub-supports 145 to each other through connecting ribs 146, the support performance of the support member 10 can be guaranteed while increasing the flexibility of the elastic part 13. This makes it easier for the elastic part 13 to bend when the display screen 20 is bent, and the bending angle of the elastic part 13 can be better matched with the bending angle of the second bending segment 212. This can further prevent the support member 10 from squeezing the display screen 20 and improve the service life of the display screen 20.

[0145] Please see Figure 17 and Figure 18 , Figure 17 yes Figure 8 A partial structural schematic diagram of the display module 100 in the second embodiment of the electronic device 500 shown. Figure 18 yes Figure 17 A partial structural diagram of the support member 10 in the display module 100 is shown. Figure 17 This is a partial structural diagram of the display module 100 when the electronic device 500 is in the unfolded state.

[0146] This embodiment and Figure 12 The difference in the illustrated embodiment is that, in this embodiment, when the support member 10 is in the unfolded state and the elastic part 13 is in the pre-stretched state, along the width direction of the support member 10, the lengths of the plurality of tension ribs 15 are the same or approximately the same, and the bending degree of the tension rib 15 located in the middle is greater than that of the tension ribs 15 located on both sides. When the elastic part 13 is stretched from the pre-stretched state to the stretched state, the stretching amount of the tension rib 15 located in the middle is greater than that of the tension ribs 15 located on both sides. For example, when the elastic part 13 is in the pre-stretched state, the lengths of the first tension rib 151, the second tension rib 152, and the third tension rib 153 are the same; when the elastic part 13 is in the stretched state, the length of the first tension rib 151 is greater than the lengths of the second tension rib 152 and the third tension rib 153. That is, when the elastic part 13 is stretched from the pre-stretched state to the stretched state, the stretching amount of the first tension rib 151 is greater than the stretching amount of the second tension rib 152 and the stretching amount of the third tension rib 153.

[0147] The middle tension rib 15 and the second curved section 212 are positioned opposite each other at their center positions in the width direction along the thickness direction of the display screen 20. That is, the second tension rib 152 and the second curved section 212 are positioned opposite each other at their center positions in the width direction along the thickness direction of the display screen 20.

[0148] Please see Figure 19 , Figure 19 yes Figure 17 The diagram shows the structure of the display module 100 in a stretched state.

[0149] When the display module 100 is subjected to tensile forces on opposite sides in the width direction (X direction) of the display module 100, the display screen 20 is stretched in the width direction, thereby forming a dent 1 in the second bending section 212. Simultaneously, the tension rib 15 is stretched along the width direction of the support member 10 and is in a stretched state. At this time, the tension rib 15 becomes longer, that is, the dimension of the tension rib 15 along the width direction of the support member 10 increases. At the same time, the distance between two adjacent supports 14 increases, and the dimension of the elastic part 13 along the width direction of the support member 10 increases.

[0150] Please combine Figure 20 and Figure 21 , Figure 20 yes Figure 17 The diagram shows a simplified structure of the display module 100 in a folded state. Figure 21 yes Figure 20 A partial structural diagram of the support member 10 in the display module 100 shown.

[0151] When the electronic device 500 rotates from an unfolded state to a folded state, the first curved portion 21 of the display screen 20 bends. Specifically, the first curved segment 211 and the third curved segment 213 rotate toward each other, while the second curved segment 212 bends toward the base 310. When the first curved portion 21 bends, the second curved segment 212 is stretched in the width direction of the display screen 20. At this time, the display module 100 is in a stretched state. It can be understood that when the display module 100 bends, the display module 100 is in a stretched state. That is, when the angle between the first housing 210 and the second housing 220 is greater than or equal to 0 degrees and less than 180 degrees, the display module 100 is in a stretched state.

[0152] Combination Figure 19 and Figure 20 When the electronic device 500 rotates from the unfolded state to the folded state, the display screen 20 also drives the first support part 11 and the second support part 12 to rotate towards each other, thereby causing the elastic part 13 to bend towards the base 310 and putting the support member 10 in a bent state. When the support member 10 is in a bent state, the elastic part 13 is in a stretched state, and the tension rib 15 is stretched along the width direction of the support member 10 and is in a stretched state. At this time, the tension rib 15 becomes longer, that is, the dimension of the tension rib 15 along the width direction of the support member 10 increases. Furthermore, the length of the tension rib 15 located in the middle is greater than the length of the tension ribs 15 located on both sides. Specifically, the length of the second tension rib 15 is greater than the length of the first tension rib 15 and the length of the third tension rib 15. At the same time, the distance between two adjacent support bodies 14 increases, and the dimension of the elastic part 13 along the width direction of the support member 10 increases.

[0153] It is understandable that when the electronic device 500 is in a folded state, the radius of curvature of the second curved segment 212 gradually increases from its center position to both sides in the width direction, that is, the degree of curvature gradually decreases. In other words, the degree of curvature at the center position of the first curved segment 211 in the width direction is greater than the degree of curvature on both sides of the first curved segment 211 in the width direction.

[0154] In this embodiment, when the elastic part 13 changes from a pre-stretched state to a stretched state, the stretching amount of the tension rib 15 located at the middle position in the width direction of the support member 10 is set to be greater than the stretching amount of the tension ribs 15 located on both sides. This makes the length of the tension rib 15 located at the middle position greater than the length of the tension ribs 15 located on both sides when the electronic device 500 is in a folded state. This results in the tension rib 15 located at the middle position having a larger deformation and the elastic part 13 having a larger bending angle. This provides a larger clearance space for the bending of the center position in the width direction of the display screen 20 and a larger clearance space for the bending of the entire display screen 20. This can further avoid squeezing the display screen 20 and improve the display effect and service life of the display screen 20.

[0155] Meanwhile, in this embodiment, by setting the length of the multiple tension ribs 15 to be the same, the distance between two adjacent support bodies 14 is equal, thereby ensuring the support performance of the elastic part 13, that is, ensuring the support performance of the support member 10 on the display screen 20, and thus ensuring the reliability and display effect of the display screen 20.

[0156] Please see Figure 22 , Figure 22 yes Figure 8 This is a partial structural diagram of the display module 100 in the electronic device 500 in the third embodiment. Figure 22 This is a partial structural diagram of the display module 100 when the electronic device 500 is in the unfolded state. It is understood that... Figure 22 The support member 10 is in the unfolded state, and the elastic part 13 is in the pre-stretched state.

[0157] This embodiment and Figure 18 The difference in the illustrated embodiment is that, in this embodiment, the elastic part 13 has six support bodies 14 and five tension ribs 15. Along the positive X-axis, the six support bodies 14 are respectively the first support body 141, the second support body 142, the third support body 143, the fourth support body 144, the fifth support body 147, and the sixth support body 148, and the five tension ribs 15 are respectively the first tension rib 151, the second tension rib 152, the third tension rib 153, the fourth tension rib 155, and the fifth tension rib 156.

[0158] The first tension rib 151 is connected between the first support body 141 and the second support body 142, the second tension rib 152 is connected between the second support body 142 and the third support body 143, the third tension rib 153 is connected between the third support body 143 and the fourth support body 144, the fourth tension rib 155 is connected between the fourth support body 144 and the fifth support body 147, and the fifth tension rib 156 is connected between the fifth support body 147 and the sixth support body 148.

[0159] When the support member 10 is in the unfolded state and the elastic part 13 is in the pre-stretched state, along the width direction of the support member 10, the lengths of the multiple tension ribs 15 are the same or approximately the same, and the bending degree of the tension rib 15 located in the middle is greater than that of the tension ribs 15 located on both sides. When the elastic part 13 is stretched from the pre-stretched state to the stretched state, the stretching amount of the tension rib 15 located in the middle is greater than that of the tension ribs 15 located on both sides.

[0160] Specifically, when the elastic part 13 is in the pre-stretched state, the lengths of the first tension rib 151, the second tension rib 152, the third tension rib 153, the fourth tension rib 155, and the fifth tension rib 156 are the same. When the elastic part 13 is in the stretched state, the length of the third tension rib 153 is greater than the lengths of the second tension rib 152 and the fourth tension rib 155, while the lengths of the first tension rib 151, the fifth tension rib 156, the second tension rib 152, and the fourth tension rib 155 are all equal. That is, when the elastic part 13 is stretched from the pre-stretched state to the stretched state, the stretching amount of the third tension rib 153 is greater than the stretching amount of the second tension rib 152 and the fourth tension rib 155, while the stretching amounts of the first tension rib 151, the fifth tension rib 156, the second tension rib 152, and the fourth tension rib 155 are all equal.

[0161] Alternatively, when the elastic part 13 is stretched from the pre-stretched state to the stretched state, the stretching amount of the third tension rib 153 is greater than the stretching amount of the second tension rib 152 and the stretching amount of the fourth tension rib 155. The stretching amount of the second tension rib 152 is greater than the stretching amount of the fourth tension rib 155, and the stretching amount of the fifth tension rib 156 is also greater than the stretching amount of the fifth tension rib 156.

[0162] When the electronic device 500 rotates from the unfolded state to the folded state, so that the support member 10 is in the stretched state, all five tension ribs 15 elastically elongate, and the length of the third tension rib 153 is greater than the lengths of the first tension rib 151, the second tension rib 152, the fourth tension rib 155, and the fifth tension rib 156. When the electronic device 500 rotates from the folded state to the unfolded state, so that the support member 10 returns to the unfolded state, all five tension ribs 15 elastically return, thereby causing the first curved portion 21 of the display screen 20 to retract inward. This reduces or even eliminates the dent 1 generated when the display screen 20 is in the bent state, reduces or even avoids light and shadow creases on the display screen 20, improves the display effect of the display screen 20, and enhances the user experience.

[0163] In this embodiment, by increasing the number of support bodies 14 and tension ribs 15, the deformation of support member 10 from pre-stretched state to stretched state can be increased, thereby increasing the bending angle of support member 10 when display module 100 is in folded state, which can provide more clearance for bending of display screen 20, further avoid damage to display screen 20, and improve the service life of display screen 20.

[0164] Meanwhile, in this embodiment, by increasing the number of support bodies 14 and tension ribs 15, the deformation of the support member 10 from the pre-stretched state to the stretched state can be increased. The deformation of the elastic part 13 during elastic recovery can also be increased. This can increase the amount of retraction when the elastic part 13 retracts inward to drive the first bent part 21 of the display screen 20 during elastic recovery. This can further reduce the dent 1 generated when the display screen 20 is bent and further prevent the display screen 20 from having light and shadow creases, thereby improving the display effect of the display screen 20.

[0165] Furthermore, in this embodiment, when the elastic part 13 changes from a pre-stretched state to a stretched state, the stretching amount of the tension rib 15 located in the middle of the width direction of the support member 10 is set to be greater than the stretching amount of the tension ribs 15 located on both sides. This results in the length of the tension rib 15 located in the middle position being greater than the length of the tension ribs 15 located on both sides when the electronic device 500 is in a folded state. This allows the tension rib 15 located in the middle position to have a larger deformation and the elastic part 13 to have a larger bending angle. This provides a larger clearance space for the bending of the center position of the display screen 20 in the width direction and a larger clearance space for the bending of the entire display screen 20. This can further avoid squeezing the display screen 20 and improve the display effect and service life of the display screen 20.

[0166] Please continue reading. Figure 22In this embodiment, any one or more of the multiple connecting ribs 146 are reinforcing connecting ribs 1461. The width of the reinforcing connecting rib 1461 is the same as the width of the two sub-supports 145 connected to it, and the thickness of the reinforcing connecting rib 1461 is the same as the thickness of the two sub-supports 145 connected to it. In this embodiment, the reinforcing connecting rib 1461 and the two sub-supports 145 connected to it are integrally formed. The reinforcing connecting rib 1461 and the two sub-supports 145 connected to it can be understood as a larger reinforcing support 2.

[0167] Specifically, the first support body 141 is provided with a reinforcing connecting rib 1461, which, together with the sub-support body 145 connected thereto, forms a reinforcing support body 2. The size of the reinforcing support body 2 is larger than that of the sub-support body 145, so as to improve the structural strength of the elastic part 13 and the support member 10, thereby improving the support performance of the support member 10 for the display screen 20.

[0168] The second support 142 is provided with a reinforcing connecting rib 1461, which, together with the sub-support 145 connected thereto, forms a reinforcing support 2. The reinforcing connecting rib 1461 in the first support 141 is offset from the reinforcing connecting rib 1461 in the first support 141 along the width direction of the support member 10. The reinforcing support 2 in the first support 141 is also offset from the reinforcing support 2 in the second support 142 along the width direction of the support member 10, so that the reinforcing support 2 is more evenly distributed in the elastic part 13. This improves the uniformity of the structural strength of the elastic part 13, avoids areas with excessively low strength in the elastic part 13, and further enhances the structural strength of the support member 10 and improves the support performance of the support member 10 for the display screen 20.

[0169] Both the fourth support 144 and the fifth support 147 are provided with reinforcing support 2. The reinforcing support 2 in the fourth support 144 and the reinforcing support 2 in the fifth support 147 are staggered along the width direction of the support member 10, so as to make the reinforcing support 2 more evenly distributed in the elastic part 13, thereby further improving the uniformity of the structural strength of the elastic part 13.

[0170] In one implementation, such as Figure 23 As shown, the first support body 141 is provided with two reinforcing connecting ribs 1461, which are arranged adjacently along the Y direction. The two reinforcing connecting ribs 1461 connect the three sub-support bodies 145 arranged sequentially along the Y direction to form a reinforcing support body 2. In this embodiment, the size of the reinforcing support body 2 in the first support body 14 is larger than that of the first support body 14. Figure 22In the illustrated embodiment, the reinforcing support 2 in the first support 14 can further enhance the structural strength of the elastic part 13 and the support member 10, and further improve the support performance of the support member 10 for the display screen 20. Alternatively, the first support 141 can also be provided with three or four or more reinforcing connecting ribs 1461. The first support 141 is formed by the sub-support 145 and multiple reinforcing support ribs 2 of different sizes spaced apart. Here, there is no specific limitation on the number and placement of the reinforcing connecting ribs 1461. Alternatively, the first support 141 can also be a long strip structure with uniform length and thickness.

[0171] The fifth support 147 is provided with two reinforcing connecting ribs 1461, which are arranged adjacently along the Y direction. The two reinforcing connecting ribs 1461 connect the three sub-supports 145 arranged sequentially along the Y direction to form a reinforcing support 2. That is, the fifth support 147 is symmetrically arranged with the first support 141, thereby improving the uniformity of the structural strength of the elastic part 13.

[0172] in, Figure 22 In the embodiment shown, the tension rib 15 and the support body 14 are integrally molded to improve the connection stability between the tension rib 15 and the support body 14, thereby improving the structural stability of the elastic part 13 and the support member 10.

[0173] like Figure 24 As shown, in one embodiment, the tension rib 15 and the support body 14 can be fixedly connected via shaft holes. For example, each sub-tension rib 154 includes two connecting shafts 1541. The two connecting shafts 1541 are respectively located at opposite ends of the extension direction of the sub-tension rib 154. Each sub-support body 145 is provided with a connecting hole 1451 corresponding to the connecting shaft 1541. The sub-tension rib 154 is disposed between two adjacent sub-support bodies 145, and the two connecting shafts 1541 are respectively disposed in the connecting holes 1451 of the corresponding two sub-support bodies 145, and are fixedly connected to the corresponding sub-support bodies 145, thereby achieving a fixed connection between the sub-tension rib 154 and the corresponding sub-support body 145.

[0174] Please see Figure 25 , Figure 25 yes Figure 8 This is a partial structural diagram of the display module 100 in the electronic device 500 according to the fourth embodiment. Figure 25 This is a partial structural diagram of the display module 100 when the electronic device 500 is in the unfolded state. It is understood that... Figure 25 The support member 10 is in the deployed state, and the elastic part 13 is in the pre-stretched state. It should be noted that... Figure 25 Only a partial structure of the elastic part 13 in the support member 10 is shown. In reality, the elastic part 13 can be composed of multiple parts that are... Figure 25 Composed of repeating units that are the same, similar, or different.

[0175] This embodiment and Figure 10 The difference in the illustrated embodiment is that, in this embodiment, when the support member 10 is in the unfolded state and the elastic part 13 is in the pre-stretched state, the lengths of the multiple tension ribs 15 are the same, and the widths of some or all of the multiple tension ribs 15 are different. For example, when the elastic part 13 is in the pre-stretched state, the lengths of the first tension rib 151, the second tension rib 152, and the third tension rib 153 are all the same, the width of the first tension rib 151 is greater than the width of the second tension rib 152, and the width of the second tension rib 152 is greater than the width of the third tension rib 153. Here, "the width of the tension rib 15" refers to the dimension of the tension rib 15 along the Y direction.

[0176] It is understandable that when the elastic part 13 is in a pre-stretched state and the length of the tension ribs 15 is consistent, the smaller the width of the tension ribs 15, the greater the stretching amount when the tension ribs 15 are in a stretched state, and the larger the width of the tension ribs 15, the smaller the stretching amount when the tension ribs 15 are in a stretched state.

[0177] In the actual design process, the width of the tension ribs 15 at different positions can be adjusted according to the stretching requirements of the elastic part 13 at different locations. For example, the width of the tension ribs 15 gradually decreases along the direction from the first support part 11 to the second support part 12. Alternatively, along the width direction of the support member 10, the width of the tension rib 15 in the middle is smaller than the width of the tension ribs 15 on both sides. This can increase the stretching amount of the tension rib 15 in the middle position when the electronic device 500 is in a folded state, thereby providing more clearance for bending at the center position of the display screen 20 in the width direction, further avoiding compression of the display screen 20, and improving the display effect and service life of the display screen 20.

[0178] Please see Figure 26 , Figure 26 yes Figure 8 A partial structural diagram of the display module 100 in the fifth embodiment of the electronic device 500 shown. Wherein, Figure 26 This is a partial structural diagram of the display module 100 when the electronic device 500 is in the unfolded state. It is understood that... Figure 26 The support member 10 is in the unfolded state, and the elastic part 13 is in the pre-stretched state.

[0179] This embodiment and Figure 25The difference in the illustrated embodiment is that, in this embodiment, the tension rib 15 is made of an elastic material and has a rectangular or square structure. The tension rib 15 is provided with a tension hole 157. The tension hole 157 extends through the tension rib 15 along its thickness direction. During the stretching process, the size of the tension hole 157 increases along the width direction of the support member 10, thereby achieving elastic elongation of the elastic portion 13 and allowing the support member 10 to change from an unfolded state to a bent state.

[0180] In this embodiment, the tension hole 157 is strip-shaped, and its length direction is parallel to the Y direction. In other embodiments, the tension hole 157 can also be a round hole, a square hole, an elliptical hole, or a hole of other shapes. Each tension rib 15 has multiple tension holes 157, which are spaced apart along the width direction of the support member 10 to form a row of tension holes 157. In this embodiment, each tension rib 15 has two tension holes 157, and the two rows of tension holes 157 are spaced apart along the width direction of the tension rib 15, that is, spaced apart along the Y direction. In other embodiments, each tension rib 15 can also have one row of tension holes 157, or three or four or more rows of tension holes 157.

[0181] In this embodiment, the tension rib 15 is made of elastic material, and the elastic part 13 can be elastically elongated and the support member 10 can be stretched by setting tension holes 157 in the tension rib 15. This simplifies the manufacturing process of the support member 10, thereby simplifying the manufacturing process of the display module 100 and the electronic device 500, and reducing the manufacturing cost of the electronic device 500.

[0182] Furthermore, in this embodiment, by providing tension holes 157 on the tension rib 15 made of elastic material, the tension rib 15 elongates not only through the movement of polymer chains in the elastic material but also through the deformation of the tension holes 157 when it elastically elongates. This increases the deformation of the tension rib 15, thereby providing more space for the bending of the display screen 20 and further avoiding compression of the display screen 20.

[0183] The number of tension holes 157 on the multiple tension ribs 15 can be the same, completely different, or partially the same. It is understood that when the elastic part 13 is in a pre-stretched state, the tension ribs 15 have consistent lengths, and the shape and size of the tension holes 157 on the tension ribs 15 are consistent, the more tension holes 157 on the tension ribs 15, the greater the stretching amount when the tension ribs 15 are in a stretched state; the fewer tension holes 157 on the tension ribs 15, the smaller the stretching amount when the tension ribs 15 are in a stretched state.

[0184] In the actual design process, the number of tension holes 157 on the tension ribs 15 at different positions can be adjusted according to the tension requirements of the elastic part 13 at different positions. For example, along the direction from the first support part 11 to the second support part 12, that is, along the positive X-axis direction, the number of tension holes 157 on the tension ribs 15 gradually decreases. For example, the first tension rib 151 has two rows of tension holes 157, with four tension holes 157 in each row; the second tension rib 152 has two rows of tension holes 157, with three tension holes 157 in each row; and the third tension rib 153 has two rows of tension holes 157, with two tension holes 157 in each row.

[0185] Alternatively, along the width direction of the support member 10, the number of tension holes 157 on the middle tension rib 15 is greater than the number of tension holes 157 on the tension ribs 15 on both sides. This increases the amount of tension on the middle tension rib 15 when the electronic device 500 is in a folded state, thereby providing more clearance for bending at the center of the display screen 20 in the width direction, further avoiding compression of the display screen 20, and improving the display effect and service life of the display screen 20.

[0186] Please see Figure 27 , Figure 27 yes Figure 8 A partial structural diagram of the display module 100 in the electronic device 500 shown in the sixth embodiment. Wherein, Figure 27 This is a partial structural diagram of the display module 100 when the electronic device 500 is in the unfolded state. It is understood that... Figure 27 The support member 10 is in the unfolded state, and the elastic part 13 is in the pre-stretched state.

[0187] This embodiment and Figure 25 The difference in the illustrated embodiment is that, in this embodiment, the tension rib 15 is dumbbell-shaped. Each tension rib 15 includes a first connecting segment 1501, a tension segment 1503, and a second connecting segment 1502. The first connecting segment 1501 and the second connecting segment 1502 are respectively connected to opposite ends of the elastic deformation direction of the tension segment 1503, that is, to opposite ends of the length direction of the tension segment 1503.

[0188] The tension rib 15 is made of an elastic material. The width of the tension section 1503 is smaller than the width of the first connecting section 1501 and the width of the second connecting section 1502. The width of the first connecting section 1501 gradually decreases towards the tension rib 15 until it matches the width of the tension rib 15. Simultaneously, the width of the second connecting section 1502 gradually decreases towards the tension rib 15 until it matches the width of the tension rib 15. In other words, the width of the tension rib 15 gradually decreases from the first connecting section 1501 to the tension section 1503, and from the second connecting section 1502 to the tension section 1503. This avoids stress concentration during tensioning caused by abrupt changes in the width of the tension rib 15, thereby increasing its strength.

[0189] like Figure 27 As shown, the tension rib 15 is positioned between two adjacent supports 14, with a first connecting segment 1501 connected to one of the supports 14 and a second connecting segment 1502 connected to the other support 14. When the support member 10 switches from the unfolded state to the bent state, the elastic part 13 switches from the pre-stretched state to the stretched state, the tension rib 15 is stretched, the stretching segment 1503 is stretched, and the dimension of the stretching segment 1503 increases along the width direction of the support member 10.

[0190] In this embodiment, the tension rib 15 is made of elastic material, and by setting a tension section 1503 with a reduced width in the tension rib 15, the elastic part 13 can be elastically elongated and the support member 10 can be stretched. This simplifies the manufacturing process of the support member 10, thereby simplifying the manufacturing process of the display module 100 and the electronic device 500, and reducing the manufacturing cost of the electronic device 500.

[0191] In this context, the widths of the stretching segments 1503 of the multiple tension ribs 15 can be exactly the same, completely different, or partially the same. It is understood that when the elastic part 13 is in a pre-stretched state and the lengths of the tension ribs 15 are consistent, the smaller the width of the stretching segment 1503 of the tension rib 15, the greater the stretching amount when the tension rib 15 is in the stretched state; conversely, the larger the width of the stretching segment 1503 of the tension rib 15, the smaller the stretching amount when the tension rib 15 is in the stretched state.

[0192] In the actual design process, the width of the stretching section 1503 of the tension rib 15 at different positions can be adjusted according to the stretching requirements of the elastic part 13 at different positions. For example, the width of the tension rib 15 gradually decreases along the direction from the first support part 11 to the second support part 12. Alternatively, along the width direction of the support member 10, the width of the tension rib 15 in the middle is smaller than the width of the tension ribs 15 on both sides. This can increase the stretching amount of the tension rib 15 in the middle position when the electronic device 500 is in a folded state, thereby providing more clearance for bending at the center position of the display screen 20 in the width direction, further avoiding compression of the display screen 20, and improving the display effect and service life of the display screen 20.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
