Description

Technical Field

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

[0002] With the development of technology and the demands of the electronic device market, foldable electronic devices are becoming increasingly widely used. Traditional foldable electronic devices include a display module, a housing, and a folding mechanism. The display module can be fixed to the housing, and the folding mechanism can fold or unfold the housing and display module relative to each other. The display module generally includes a display panel and a support component, which supports the display panel. To ensure the bending performance of the support component in the bending area, the material of the support component is generally made of fibers with a low modulus of elasticity. However, because the modulus of elasticity of the support component is low in the areas where bending is not required (i.e., the non-bending area), when the support component is fixed to the display screen, the flatness of the non-bending area of ​​the display module is low, resulting in poor lighting and shadows in the non-bending area. Summary of the Invention

[0003] This application provides a support member, a display module, and an electronic device, wherein the support member can balance good bending performance and high rigidity.

[0004] In a first aspect, this application provides a support member. Along a first direction, the support member includes a first fixing portion, a first bending portion, and a second fixing portion arranged sequentially. Along a second direction, the support member includes multiple layers of fibers stacked together, the second direction being different from the first direction. The multiple fiber layers include a composite layer, the modulus of the composite layer in the region of the first bending portion being a first modulus, the modulus of the composite layer in the region of the first fixing portion being a second modulus, and the modulus of the composite layer in the region of the second fixing portion being a third modulus, both the second and third moduli being greater than the first modulus. The support member is capable of bending around a third direction at the first bending portion, the third direction being different from both the first and second directions. The angle between the fiber arrangement direction of the composite layer in the region of the first fixing portion and the fiber arrangement direction of the composite layer in the region of the first bending portion, and the angle between the fiber arrangement direction of the composite layer in the region of the second fixing portion and the fiber arrangement direction of the composite layer in the region of the first bending portion, are both within the range of -10° to 10°.

[0005] Understandably, by setting the second and third moduli to be greater than the first modulus, the modulus of the composite layer in the first bending region is lower, which is less likely to affect the bending performance of the composite layer in the first bending region. Furthermore, the higher moduli of the composite layer in the first fixing region and the second fixing region result in better support from both the first and second fixing regions of the support member. Thus, when the support member is applied to a display module, the display module can achieve both good bending performance and high flatness, resulting in better light and shadow effects and a superior user experience and visual experience.

[0006] It is understandable that by setting the angle between the fiber arrangement direction of the composite layer in the first fixing part region and the fiber arrangement direction of the composite layer in the first bending part region, and the angle between the fiber arrangement direction of the composite layer in the second fixing part region and the fiber arrangement direction of the composite layer in the first bending part region, all within the range of -10° to 10°, the fiber arrangement directions of the composite layer in the first fixing part region, the fiber arrangement direction of the composite layer in the first bending part region, and the fiber arrangement direction of the composite layer in the second fixing part region can be approximately parallel. The processing technology of the composite layer is simpler, and it is easier to process fiber layers using different materials in the first fixing part, the first bending part, and the second fixing part regions.

[0007] In one possible implementation, the angles between the fiber arrangement direction of the composite layer in the region of the first fixing part, the fiber arrangement direction of the composite layer in the region of the first bending part, the fiber arrangement direction of the composite layer in the region of the second fixing part, and the third direction are all within the range of -10° to 10°.

[0008] Understandably, by setting the angles between the fiber arrangement directions of the composite layer in the first fixing part, the first bending part, and the second fixing part, and a third direction, all within the range of -10° to 10°, and by keeping these angles relatively small, the modulus of the composite layer in the first bending part can be kept low, thus minimizing its bending performance. Furthermore, by setting the angles between the fiber arrangement directions of the composite layer in the first fixing part, the first bending part, and the second fixing part, and a third direction, the processing technology of the composite layer is simpler, and it is easier to manufacture fiber layers using different materials in the first fixing part, the first bending part, and the second fixing part.

[0009] In one possible implementation, the multilayer fiber layer includes a first single layer located on one side of the composite layer; the angle between the fiber arrangement direction of the first single layer in the region of the first bend and the fiber arrangement direction of the composite layer in the region of the first bend is α, satisfying: -90°<a≤-20°, or, satisfying: 20°≤a<90°, or, the fiber arrangement direction of the first single layer in the region of the first bend is perpendicular to the fiber arrangement direction of the composite layer in the region of the first bend.

[0010] It is understandable that by setting the range of angle α between the fiber arrangement direction of the first single layer in the first bending region and the fiber arrangement direction of the composite layer in the first bending region, the first single layer and the composite layer in the first bending region are arranged alternately. In this way, the first bending region can have high rigidity, ensuring both bending performance and sufficient support.

[0011] In one possible implementation, the fiber arrangement direction of the first single layer in the region of the first fixing part, the fiber arrangement direction of the first single layer in the region of the second fixing part, and the fiber arrangement direction of the first single layer in the region of the first bending part are all the same.

[0012] It is understandable that the first single layer and the composite layer in the first fixing part can be arranged alternately in the same area, allowing the first fixing part to have high rigidity and thus sufficient support. Similarly, the first single layer and the composite layer in the second fixing part can be arranged alternately in the same area, allowing the second fixing part to have high rigidity and thus sufficient support.

[0013] In one possible implementation, the multilayer fiber layer includes a second single layer located on the side of the composite layer away from the first single layer; the angle between the fiber arrangement direction of the second single layer in the region of the first bend and the fiber arrangement direction of the composite layer in the region of the first bend is b, satisfying: -90°<b≤-20°, or, satisfying: 20°≤b<90°, or, the fiber arrangement direction of the second single layer in the region of the first bend is perpendicular to the fiber arrangement direction of the composite layer in the region of the first bend.

[0014] Understandably, by setting the range of angle 'b' between the fiber arrangement direction of the second single layer in the first bending region and the fiber arrangement direction of the composite layer in the first bending region, the second single layer and the composite layer in the first bending region are arranged alternately. In this way, the first bending region can have high rigidity, ensuring both bending performance and sufficient support.

[0015] In one possible implementation, the first modulus is in the range of 220 GPa to 250 GPa.

[0016] Understandably, by setting the first modulus within the range of 220Gpa to 250Gpa, the lower the first modulus, the lower the modulus of the composite layer at the first bending point, which is less likely to affect the bending performance of the composite layer in the first bending point area, resulting in a better user experience.

[0017] In one possible implementation, the second modulus is in the range of 350 GPa to 400 GPa, or the second modulus is in the range of 700 GPa to 1000 GPa.

[0018] It is understandable that by setting the second modulus in the range of 350Gpa to 400Gpa, the second modulus is higher, the modulus of the composite layer in the first fixing part is higher, and the support of the first fixing part of the support member is better.

[0019] It is understandable that by setting the second modulus in the range of 700Gpa to 1000Gpa, the second modulus is higher, the modulus of the composite layer in the first fixing part is higher, and the support of the first fixing part of the support member is better.

[0020] In one possible implementation, the third modulus is in the range of 350 GPa to 400 GPa, or the third modulus is in the range of 700 GPa to 1000 GPa.

[0021] It is understandable that by setting the third modulus in the range of 350Gpa to 400Gpa, the higher the third modulus, the higher the modulus of the composite layer in the second fixing part, and the better the support of the second fixing part of the support member.

[0022] It is understandable that by setting the third modulus in the range of 700Gpa to 1000Gpa, the higher the third modulus, the higher the modulus of the composite layer in the second fixing part, and the better the support of the second fixing part of the support member.

[0023] In one possible implementation, the difference between the first modulus and the second modulus is greater than or equal to 50 GPa.

[0024] Understandably, by setting the difference between the first and second moduli to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the first bending portion of the support component is low, resulting in good bending performance. Conversely, it ensures that the modulus of the first fixing portion of the support component is high, resulting in good support performance. Thus, when the support component is applied to a display module, the display module can achieve both good bending performance and high flatness, leading to a better user experience and visual experience.

[0025] In one possible implementation, the difference between the first modulus and the third modulus is greater than or equal to 50 GPa.

[0026] Understandably, by setting the difference between the first and third moduli to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the first bending portion of the support component is low, resulting in good bending performance. Simultaneously, it ensures that the modulus of the second fixing portion of the support component is high, leading to better support. Thus, when the support component is applied to a display module, the display module can achieve both good bending performance and high flatness, resulting in a superior user experience and visual experience.

[0027] In one possible implementation, the composite layer in the region of the first bend uses T300 carbon fiber or T700 carbon fiber.

[0028] Understandably, T300 or T700 carbon fiber has a lower modulus, resulting in a lower modulus of the composite layer at the first bend, which makes it less likely to affect the bending performance of the composite layer in the first bend area.

[0029] In one possible implementation, the composite layer in the region of the first fixing part uses M40 carbon fiber or mesophase pitch-based carbon fiber.

[0030] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a higher modulus, the composite layer has a higher modulus in the first fixing part, the first fixing part of the support has higher rigidity, and the first fixing part of the support has better support.

[0031] In one possible implementation, the composite layer in the region of the second fixing part uses M40 carbon fiber or mesophase pitch-based carbon fiber.

[0032] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a higher modulus, the composite layer has a higher modulus in the second fixing part, the second fixing part of the support has higher rigidity, and the second fixing part of the support has better support.

[0033] In one possible implementation, the composite layer in the region of the first bend includes a first region and a second region connected sequentially along a first direction; the modulus of the first region is a fourth modulus, and the modulus of the second region is a fifth modulus, wherein the fourth modulus and the fifth modulus are different.

[0034] It is understandable that by setting the fourth and fifth moduli to be different, the modulus of the first region and the modulus of the second region can be different, and the composite layer can simultaneously possess different properties in the region of the first bending part.

[0035] In one possible implementation, the first region uses either T300 carbon fiber or T700 carbon fiber.

[0036] Understandably, T300 or T700 carbon fiber has a lower modulus, resulting in a lower modulus of the composite layer in the first region. This makes it less likely to affect the bending performance of the composite layer in the first region, leading to a better user experience.

[0037] In one possible implementation, the second region uses M40 carbon fiber or mesophase pitch-based carbon fiber.

[0038] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a higher modulus, the composite layer has a higher modulus in the second region, the support has higher rigidity in the second region, and the support in the second region has better support.

[0039] In one possible implementation, the composite layer in the region of the first bend is made of a material woven from at least two of T300 carbon fiber, M40 carbon fiber, T700 carbon fiber and mesophase pitch-based carbon fiber.

[0040] It is understandable that the composite layer can simultaneously contain materials with high modulus and materials with low modulus in any region of the first bend. The composite layer in the region of the first bend is less likely to affect the bending performance of the support and can also improve the support of the first bend.

[0041] In one possible implementation, along the fourth direction, the support member further includes a second bending portion and a third fixing portion, the second bending portion connecting the second fixing portion and the third fixing portion, wherein the fourth direction is different from the first direction; the composite layer has a sixth modulus in the region of the second bending portion and a seventh modulus in the region of the third fixing portion, the seventh modulus being greater than the sixth modulus; the support member is capable of bending around the third direction at the second bending portion; the angle between the fiber arrangement direction of the composite layer in the region of the second bending portion and the fiber arrangement direction of the composite layer in the region of the third fixing portion is in the range of -10° to 10°.

[0042] Understandably, by setting the seventh modulus to be greater than the sixth modulus, the modulus of the composite layer in the second bending region is lower, which is less likely to affect the bending performance of the composite layer in the second bending region. Furthermore, the higher modulus of the composite layer in the third fixing region results in better support from the third fixing part of the support member.

[0043] It is understandable that by setting the angle between the fiber arrangement direction of the composite layer in the second bending section and the fiber arrangement direction of the composite layer in the third fixing section to be within the range of -10° to 10°, the fiber arrangement direction of the composite layer in the second bending section and the fiber arrangement direction of the composite layer in the third fixing section can be roughly parallel. The processing technology of the composite layer is simpler, and it is easier to process fiber layers with different materials in the second bending section and the third fixing section.

[0044] In one possible implementation, the angle between the fiber arrangement direction of the composite layer in the region of the second bend and the fiber arrangement direction of the composite layer in the region of the third fixing part and the third direction is in the range of -10° to 10°.

[0045] Understandably, by setting the angles between the fiber arrangement direction of the composite layer in the second bending section and the third fixing section and the third direction to be within the range of -10° to 10°, the angles are relatively small, which is less likely to affect the bending performance of the composite layer and results in a better user experience. Furthermore, by setting the angles between the fiber arrangement direction of the composite layer in the second bending section and the third fixing section and the third direction to be within the range of -10° to 10°, the processing technology of the composite layer is simpler, and it is easier to process fiber layers using different materials in the second bending section and the third fixing section.

[0046] In one possible implementation, the multilayer fiber layer includes a first single layer located on one side of the composite layer; the angle between the fiber arrangement direction of the first single layer in the region of the second bend and the fiber arrangement direction of the composite layer in the region of the second bend is c, satisfying: -90°<c≤-20°, or, satisfying: 20°≤c<90°, or, the fiber arrangement direction of the first single layer in the region of the second bend is perpendicular to the fiber arrangement direction of the composite layer in the region of the second bend.

[0047] Understandably, by setting the range of angle c between the fiber arrangement direction of the first single layer in the second bending region and the fiber arrangement direction of the composite layer in the second bending region, the first single layer and the composite layer in the second bending region are arranged alternately. In this way, the second bending region can have high rigidity, ensuring both bending performance and sufficient support.

[0048] In one possible implementation, a second single layer of multilayer fibers is located on the side of the composite layer away from the first single layer; the angle between the fiber arrangement direction of the second single layer in the region of the second bend and the fiber arrangement direction of the composite layer in the region of the second bend is d, satisfying: -90°<d≤-20°, or, satisfying: 20°≤d<90°, or, the fiber arrangement direction of the second single layer in the region of the second bend is perpendicular to the fiber arrangement direction of the composite layer in the region of the second bend.

[0049] It is understandable that by setting the range of the angle 'd' between the fiber arrangement direction of the second single layer in the second bending region and the fiber arrangement direction of the composite layer in the second bending region, the second single layer and the composite layer in the second bending region are arranged alternately. In this way, the second bending region can have high rigidity, ensuring both bending performance and sufficient support.

[0050] In one possible implementation, the sixth modulus is in the range of 220 GPa to 250 GPa.

[0051] Understandably, by setting the sixth modulus in the range of 220 GPa to 250 GPa, the sixth modulus is relatively low, and the modulus of the composite layer in the second bending region is also relatively low, which makes it less likely to affect the bending performance of the composite layer in the second bending region.

[0052] In one possible implementation, the seventh modulus is in the range of 350 GPa to 400 GPa, or in the range of 700 GPa to 1000 GPa.

[0053] It is understandable that by setting the seventh modulus in the range of 350Gpa to 400Gpa, the seventh modulus is higher, the modulus of the composite layer in the region of the third fixing part is higher, the rigidity of the third fixing part of the support is higher, and the support of the third fixing part of the support is better.

[0054] Understandably, by setting the seventh modulus within the range of 700Gpa to 1000Gpa, the seventh modulus is higher, the modulus of the composite layer in the region of the third fixing part is higher, and the support of the third fixing part of the support member is better.

[0055] In one possible implementation, the difference between the seventh modulus and the sixth modulus is greater than or equal to 50 GPa.

[0056] Understandably, by setting the difference between the seventh and sixth moduli to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the second bending portion of the support is low, resulting in good bending performance of the second bending portion. It also ensures that the modulus of the third fixing portion of the support is high, resulting in high rigidity and good support performance of the third fixing portion.

[0057] In one possible implementation, the composite layer in the region of the second bend uses T300 carbon fiber or T700 carbon fiber.

[0058] Understandably, T300 or T700 carbon fiber has a lower modulus, resulting in a lower modulus of the composite layer at the second bend. This makes it less likely to affect the bending performance of the composite layer in the second bend area, leading to a better user experience.

[0059] In one possible implementation, the composite layer in the region of the third fixing part uses M40 carbon fiber or mesophase pitch-based carbon fiber.

[0060] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a higher modulus, the composite layer has a higher modulus in the third fixing part, the third fixing part of the support has higher rigidity, and the third fixing part of the support has better support.

[0061] Secondly, this application provides a display module. The display module is a flexible screen, and includes a display panel and a support member as described above, the support member being fixed to the non-display surface of the display panel.

[0062] Understandably, the support components provide good support for the display panel and are less likely to affect its bending performance. The display module has high flatness, good light and shadow, and good bending performance.

[0063] Thirdly, this application provides an electronic device. The electronic device includes a housing device and the aforementioned display module, the display module being mounted on the housing device, and the housing device being used to drive the display module to unfold or fold relative to each other.

[0064] It is understandable that electronic devices have a high degree of flatness, better light and shadow, and better bending performance in their display modules.

[0065] Fourthly, this application provides a method for manufacturing a support member. The method includes: spreading out a first type of fiber yarn, a second type of fiber yarn, and a third type of fiber yarn along a first direction; impregnating the spread first type of fiber yarn, second type of fiber yarn, and third type of fiber yarn with resin; curing the impregnated first type of fiber yarn, second type of fiber yarn, and third type of fiber yarn to form a composite fiber prepreg; and processing the composite fiber prepreg to form a composite layer.

[0066] Understandably, spreading out different types of fiber yarns allows for the formation of composite carbon fiber layers during the yarn spreading process, which is a relatively simple processing method.

[0067] In one possible implementation, the composite fiber prepreg is formed by hot pressing and cutting.

[0068] It is understandable that hot pressing, cutting and other processes can process composite fiber prepreg into composite layers, thus obtaining composite layer product forms.

[0069] In one possible implementation, the angle between the arrangement direction of the first type of fiber yarn, the arrangement direction of the second type of fiber yarn, the arrangement direction of the third type of fiber yarn and the third direction is in the range of -10° to 10°, wherein the third direction is different from the first direction.

[0070] It is understandable that by setting the angle between the arrangement direction of the first type of fiber yarn, the arrangement direction of the second type of fiber yarn, the arrangement direction of the third type of fiber yarn and the third direction to be within the range of -10° to 10°, the angle between the fiber arrangement direction and the third direction of the processed composite layer is within the range of -10° to 10°. The processing technology of the composite layer is simpler and it is easier to process the composite fiber layer.

[0071] In one possible implementation, after forming the composite layer, the manufacturing method further includes: spreading out a second type of fiber yarn along a first direction; impregnating the spread out second type of fiber yarn with resin; curing the pre-impregnated second type of fiber yarn to form a second type of fiber prepreg fabric; processing the second type of fiber prepreg fabric to form a first single layer; and laminating the first single layer onto the composite layer.

[0072] It is understandable that processing the second type of fiber yarn into the first single layer and stacking the first single layer on the composite layer will not easily affect the bending performance of the support, and the support performance of the support is good.

[0073] In one possible implementation, the angle between the arrangement direction of the second type of fiber yarn in the first single layer and the arrangement direction of the second type of fiber yarn in the composite layer is in the range of greater than -90° and less than or equal to -20°, or in the range of greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the first single layer is perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer.

[0074] It is understandable that by setting the angle between the arrangement direction of the second type of fiber yarn in the first single layer and the arrangement direction of the second type of fiber yarn in the composite layer to be within the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or by setting the arrangement direction of the second type of fiber yarn in the first single layer to be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer, with the first single layer and the composite layer arranged alternately, the support can have high rigidity, providing sufficient support while ensuring the bending performance of the support.

[0075] Fifthly, this application provides a method for manufacturing a support member. The method includes: laying out a first type of fiber yarn, impregnating the laid-out first type of fiber yarn with a first type of resin, and curing the impregnated first type of fiber yarn to form a first type of fiber prepreg; laying out a second type of fiber yarn, impregnating the laid-out second type of fiber yarn with a second type of resin, and curing the impregnated second type of fiber yarn to form a second type of fiber prepreg; laying out a third type of fiber yarn, impregnating the laid-out third type of fiber yarn with a third type of resin, and curing the impregnated third type of fiber yarn to form a third type of fiber prepreg; arranging the first type of fiber prepreg, the second type of fiber prepreg, and the third type of fiber prepreg along a first direction, and processing the first type of fiber prepreg, the second type of fiber prepreg, and the third type of fiber prepreg to form a composite layer.

[0076] It is understandable that different types of fiber yarns are processed into different types of fiber prepregs, and then the different types of fiber prepregs are processed into composite fiber layers to form composite layers. The processing method is also relatively simple.

[0077] In one possible implementation, the first type of fiber prepreg, the second type of fiber prepreg, and the third type of fiber prepreg are processed by hot pressing and cutting to form a composite layer.

[0078] It is understandable that hot pressing, cutting and other processes can process the first type of fiber prepreg, the second type of fiber prepreg and the third type of fiber prepreg into composite layers, thus obtaining composite layer product forms.

[0079] In one possible implementation, the angle between the arrangement direction of the first type of fiber yarn, the arrangement direction of the second type of fiber yarn, the arrangement direction of the third type of fiber yarn and the third direction is in the range of -10° to 10°, wherein the third direction is different from the first direction.

[0080] It is understandable that by setting the angle between the arrangement direction of the first type of fiber yarn, the arrangement direction of the second type of fiber yarn, the arrangement direction of the third type of fiber yarn and the third direction to be within the range of -10° to 10°, the angle between the fiber arrangement direction and the third direction of the processed composite layer is within the range of -10° to 10°. The processing technology of the composite layer is simpler and it is easier to process the composite fiber layer.

[0081] In one possible implementation, after forming the composite layer, the manufacturing method further includes: spreading out a second type of fiber yarn along a first direction; impregnating the spread out second type of fiber yarn with a second type of resin; curing the pre-impregnated second type of fiber yarn to form a second type of fiber prepreg fabric; processing the second type of fiber prepreg fabric to form a first single layer; and stacking the first single layer onto the composite layer.

[0082] It is understandable that processing the second type of fiber yarn into the first single layer and stacking the first single layer on the composite layer will not easily affect the bending performance of the support, and the support performance of the support is good.

[0083] In one possible implementation, the angle between the arrangement direction of the second type of fiber yarn in the first single layer and the arrangement direction of the second type of fiber yarn in the composite layer is in the range of greater than -90° and less than or equal to -20°, or in the range of greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the first single layer is perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer.

[0084] It is understandable that by setting the angle between the arrangement direction of the second type of fiber yarn in the first single layer and the arrangement direction of the second type of fiber yarn in the composite layer to be within the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or by setting the arrangement direction of the second type of fiber yarn in the first single layer to be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer, with the first single layer and the composite layer arranged alternately, the support can have high rigidity, providing sufficient support while ensuring the bending performance of the support.

[0106] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0107] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," "joining," and "joining" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. The relative arrangement of components A and B can be such that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, with projection C and projection D at least largely overlapping. In some embodiments, substantial overlap can be any of the following: projection C is completely located within projection D; or projection D is completely located within projection C; or projection C and projection D intersect each other, and the intersection area of ​​projection C and projection D accounts for more than 50% of projection C or projection D.

[0108] The directional terms mentioned in the embodiments of this application, such as "inner" and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0109] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. "Multiple" means at least two.

[0110] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallelism and perpendicularity, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0111] Figure 1 This is a schematic diagram of one embodiment of the electronic device 1000 provided in this application, in a flattened state. Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the electronic device 1000 in a folded state.

[0112] like Figure 1 and Figure 2 As shown, this application provides a foldable electronic device 1000. The electronic device 1000 can be a foldable device such as a mobile phone, tablet computer, personal computer, laptop computer, in-vehicle device, or wearable device. Figure 1 and Figure 2 The electronic device 1000 of the illustrated embodiment is described using a mobile phone as an example. It is understood that the number of times the electronic device 1000 can be folded is not limited to... Figure 1 and Figure 2 The indicated one time, that is, electronic device 1000 is not limited to Figure 1 and Figure 2 The illustrated two-fold electronic device. In other embodiments, the electronic device 1000 may be folded more than once, that is, the electronic device 1000 may be an electronic device with more than two folds.

[0113] It is understood that, for ease of description, the length direction of the electronic device 1000 is defined as the X-axis, the thickness direction as the Z-axis, and the extension direction of the rotation axis as the Y-axis, i.e., the width direction as the Y-axis. It is also understood that the coordinate system of the electronic device 1000 can be flexibly set according to specific needs. For example, the positive direction of the X-axis is defined as the first direction, the positive direction of the Z-axis as the second direction, the positive direction of the Y-axis as the third direction, the negative direction of the X-axis as the fourth direction, the negative direction of the Z-axis as the fifth direction, and the negative direction of the Y-axis as the sixth direction. In other embodiments, the first, second, third, fourth, fifth, and sixth directions can also be flexibly set according to needs, ensuring that the first, second, third, fourth, fifth, and sixth directions are different.

[0114] For example, the rotation axis of the electronic device 1000 can be in the Y-axis direction, and the electronic device 1000 can be unfolded or folded relative to each other along the Y-axis direction. Thus, when the electronic device 1000 is in a folded state, its size in the X-axis direction becomes smaller. In other embodiments, the rotation axis of the electronic device 1000 can also be in other directions.

[0115] Figure 3 yes Figure 1 The illustrated electronic device 1000 is shown in a partially exploded view according to one embodiment. Figure 4 yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown at line AA.

[0116] Please see Figure 3 and Figure 4 and combined Figure 1 and Figure 2 As shown, the electronic device 1000 may include a display module 100, a first housing 210, a second housing 220, and a first folding mechanism 310. The first housing 210, the second housing 220, and the first folding mechanism 310 can constitute a housing device 300 of the electronic device 1000. The display module 100 can be mounted on the housing device 300, and the housing device 300 can be used to drive the display module 100 to unfold or fold relative to each other. It is understood that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the figures below. Furthermore, the electronic device 1000 may include more or fewer structures; for example, the electronic device 1000 may also include a camera module (not shown).

[0117] Exemplarily, the first folding mechanism 310 can be connected between the first housing 210 and the second housing 220. The first folding mechanism 310 can be used to unfold or fold the first housing 210 and the second housing 220 relative to each other. It is understood that in this application, the first folding mechanism 310 can be an inner folding mechanism or an outer folding mechanism. An inner folding mechanism refers to a folding mechanism that can fold at least a portion of the display module 100 between the two housings. An outer folding mechanism refers to a folding mechanism that can fold at least a portion of the display module 100 outside the housing device 300. This application does not specifically limit the first folding mechanism 310. In this embodiment, the description is based on the example of the first folding mechanism 310 being an inner folding mechanism.

[0118] Please see Figure 3 and combined Figure 1 and Figure 2 As shown, when the first housing 210, the second housing 220, and the first folding mechanism 310 are unfolded to a flattened state, the electronic device 1000 is in a flattened state. For example, when the electronic device 1000 is in a flattened state, the first housing 210, the second housing 220, and the first folding mechanism 310 can be arranged along the X-axis direction, and can be approximately 180° apart (slight deviations are allowed, such as 165°, 177°, or 185°, etc.).

[0119] like Figure 2 and Figure 4 As shown, when the first housing 210, the second housing 220, and the first folding mechanism 310 are folded relative to each other to a folded state, the electronic device 1000 is in a folded state. Exemplarily, when the electronic device 1000 is in the folded state, the first housing 210 and the second housing 220 can be brought close together, and the first housing 210 and the second housing 220 can be stacked in the second direction Z. When the first housing 210 and the second housing 220 change from a flattened state to a folded state, the first folding mechanism 310 can enclose an accommodating space 3101. It is understood that first folding mechanisms 310 with different structures can have accommodating spaces 3101 with different shapes.

[0120] like Figure 1 and Figure 2 As shown, the display module 100 may include a first part 100a, a second part 100b, and a third part 100c connected sequentially. The second part 100b is connected between the first part 100a and the third part 100c. For example, Figure 1 The diagram is illustrated by taking the arrangement of the first part 100a, the second part 100b, and the third part 100c along the X-axis as an example. Figure 1The first part 100a, the second part 100b, and the third part 100c are schematically distinguished by dashed lines in the accompanying drawings below. In other embodiments, the first part 100a, the second part 100b, and the third part 100c may also be configured in other ways.

[0121] like Figure 1 and Figure 3 As shown, exemplarily, the first portion 100a of the display module 100 can be fixed to the first housing 210. The third portion 100c can be fixed to the second housing 220. The second portion 100b can be disposed opposite to the first folding mechanism 310. When the first folding mechanism 310 unfolds or folds the first housing 210 and the second housing 220 relative to each other, the first housing 210 can drive the first portion 100a of the display module 100 to unfold or fold, and the second housing 220 can drive the third portion 100c of the display module 100 to unfold or fold. At this time, the second portion 100b of the display module 100 can be bent around the third direction.

[0122] like Figure 1 and Figure 3 As shown, when the electronic device 1000 is in a flattened state, the display module 100 can also be in a flattened state. For example, the first portion 100a, the second portion 100b, and the third portion 100c of the display module 100 can be approximately 180° apart (slight deviations are allowed, such as 165°, 177°, or 185°). In this state, the display module 100 has a continuous, large display area, meaning it can achieve a large-screen display, resulting in a better user experience.

[0123] For example, when the electronic device 1000 is in a flattened state, at least a portion of the first folding mechanism 310 can be used to support the second part 100b of the display module 100. Thus, when the second part 100b of the display module 100 is subjected to pressing, squeezing, or impact forces, the first folding mechanism 310 can be used to improve the pressure resistance and impact resistance of the second part 100b, thereby ensuring that the second part 100b of the display module 100 is less prone to dents or other problems.

[0124] like Figure 2 and Figure 4 As shown, when the electronic device 1000 is in a folded state, the display module 100 can also be in a folded state. Exemplarily, the first portion 100a and the third portion 100c of the display module 100 can be positioned close to each other. At this time, the first portion 100a and the third portion 100c of the display module 100 can be arranged along the Z-axis direction. Furthermore, the second portion 100b of the display module 100 can be bent around a third direction.

[0125] For example, when the electronic device 1000 is in a folded state, the first part 100a, the second part 100b, and the third part 100c of the display module 100 can all be located between the first housing 210 and the second housing 220, and the second part 100b can be located within the accommodating space 3101 of the first folding mechanism 310. When the electronic device 1000 is in a folded state, since the first part 100a, the second part 100b, and the third part 100c of the display module 100 are all located between the first housing 210 and the second housing 220, the display surface of the first part 100a can face the display surface of the third part 100c, the second part 100b can be bent and disposed between the first part 100a and the third part 100c, and the second part 100b can be located within the accommodating space 3101 of the first folding mechanism 310. The first part 100a, the second part 100b, and the third part 100c of the display module 100 can be referred to as the inner screen of the display module 100. When the first housing 210 and the second housing 220 are folded, the first part 100a, the second part 100b, and the third part 100c can be folded into the space formed by the first housing 210, the second housing 220, and the first folding mechanism 310. The first part 100a, the second part 100b, and the third part 100c can therefore be referred to as the inner screen of the display module 100. This will be described in detail below with reference to the accompanying drawings.

[0126] The structure of the electronic device 1000 in some embodiments has been described in detail above with reference to the accompanying drawings. The structure of the display module 100 in some embodiments will be described in detail below with reference to the accompanying drawings.

[0127] Figure 5 yes Figure 3 The display module 100 shown is partially exploded in one embodiment.

[0128] like Figure 5 As shown, the display module 100 may include a display panel 10, a support member 20, and a protective member 30. It is understood that... Figure 5 The accompanying drawings below only schematically illustrate some components included in the display module 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 5 As defined in the accompanying drawings below. Furthermore, the display module 100 may include more or fewer structures. For example, when the display module 100 includes more structures, it may also include a back film (not shown) and a polarizer (POL) (not shown). In one embodiment, the display module 100 may also include a touchpad (not shown).

[0129] For example, the display panel 10 can be used to display images, etc. The display panel 10 can be a flexible display panel. For example, the display panel 10 can be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (MLED) display panel, a micro organic light-emitting diode (MOLED) display panel, or a quantum dot light-emitting diode (QLED) display panel, etc.

[0130] like Figure 5 As shown, along the first direction, the display panel 10 may include a first display area 11, a second display area 12, and a third display area 13 connected sequentially. In other words, the second display area 12 is connected between the first display area 11 and the third display area 13. It is understood that... Figure 5 The first display area 11, the second display area 12, and the third display area 13 are schematically distinguished by dashed lines. In other embodiments, the first display area 11, the second display area 12, and the third display area 13 may also have other configurations.

[0131] like Figure 5 As shown, along a first direction, the support member 20 may include a first fixing portion 20a, a first bending portion 20b, and a second fixing portion 20c connected in sequence. The first bending portion 20b may be connected between the first fixing portion 20a and the second fixing portion 20c. The support member 20 is capable of bending around a third direction at the first bending portion 20b. It is understood that... Figure 5 The first fixing part 20a, the first bending part 20b, and the second fixing part 20c are schematically distinguished by dashed lines. In other embodiments, the first fixing part 20a, the first bending part 20b, and the second fixing part 20c may also have other arrangements.

[0132] Figure 6A yes Figure 3 A partial cross-sectional view of one embodiment of the display module 100 at the BB line is shown. Figure 1 .

[0133] like Figure 6AAs shown, by way of example, the protective member 30 can be fixed to the display surface of the display panel 10. The support member 20 can be fixed to the non-display surface of the display panel 10. The display panel 10, the support member 20, and the protective member 30 can be connected by means of adhesive or the like.

[0134] Please see Figure 5 and combined Figure 6A As shown, by way of example, the first fixing part 20a of the support member 20 can be disposed opposite to the first display area 11 of the display panel 10, the first bending part 20b of the support member 20 can be disposed opposite to the second display area 12 of the display panel 10, and the second fixing part 20c of the support member 20 can be disposed opposite to the third display area 13 of the display panel 10.

[0135] It is understood that the first fixing part 20a of the support member 20, the first display area 11 of the display panel 10, and a part of the protective member 30 can constitute the first part 100a of the display module 100 (see [link]). Figure 4 As part of the display module 100, the first bent portion 20b of the support member 20, the second display area 12 of the display panel 10, and a portion of the protective member 30 can constitute the second part 100b of the display module 100 (see [link]). Figure 4 As part of the display module 100, the first fixing part 20a of the support member 20, the third display area 13 of the display panel 10, and a part of the protective member 30 can constitute the third part 100c of the display module 100 (see [link]). Figure 4 Part of ).

[0136] Please see Figure 5 and combined Figure 3 and Figure 4 As shown, exemplarily, the first fixing portion 20a of the support member 20 can be fixed to the first housing 210. The second fixing portion 20c can be fixed to the second housing 220. The first bending portion 20b can be disposed opposite to the first folding mechanism 310. In other embodiments, the first bending portion 20b can be fixedly connected to the first folding mechanism 310.

[0137] Please see Figure 5 and combined Figure 1 and Figure 3As shown, exemplarily, when the electronic device 1000 is in a flattened state, the display panel 10, the support member 20, and the protective member 30 can all be in a flattened state. Exemplarily, the first display area 11, the second display area 12, and the third display area 13 of the display panel 10 can be approximately 180° (with slight deviations allowed, such as 165°, 177°, or 185°). Furthermore, the first fixing portion 20a, the first bending portion 20b, and the second fixing portion 20c of the support member 20 can form a plate-like structure. In other words, the first fixing portion 20a, the first bending portion 20b, and the second fixing portion 20c can be approximately 180° (with slight deviations allowed, such as 165°, 177°, or 185°).

[0138] Please see Figure 5 and combined Figure 2 and Figure 4 As shown, exemplarily, when the electronic device 1000 is in a folded state, the display panel 10 can also be in a folded state. The first display area 11, the second display area 12, and the third display area 13 of the display panel 10 can be located inside the electronic device 1000. Exemplarily, the first display area 11 and the third display area 13 of the display panel 10 can be arranged close to each other. In this case, the first display area 11 and the third display area 13 of the display panel 10 can be arranged along the Z-axis direction. Furthermore, the second display area 12 of the display panel 10 can be bent around a third direction.

[0139] Furthermore, when the electronic device 1000 is in a folded state, the support member 20 can also be folded. For example, the first fixing portion 20a and the second fixing portion 20c of the support member 20 can be arranged close together. At this time, the first fixing portion 20a and the second fixing portion 20c of the support member 20 can be stacked along the Z-axis direction. In addition, the first bending portion 20b of the support member 20 can be bent. The first fixing portion 20a, the first bending portion 20b, and the second fixing portion 20c of the support member 20 can form an accommodating space. The first display area 11, the second display area 12, and the third display area 13 of the display panel 10 can be located within this accommodating space.

[0140] In addition, when the electronic device 1000 is in a folded state, the protective component 30 can also be folded.

[0141] Figure 6B yes Figure 3 A partial cross-sectional view of one embodiment of the display module 100 at the BB line is shown. Figure 2 .

[0142] like Figure 6BAs shown, exemplarily, along the Z-axis direction, the display panel 10 may include a display body 10a, a first adhesive layer 10b, and a film layer 10c. The display body 10a and the film layer 10c may be located on opposite sides of the first adhesive layer 10b and fixedly connected to it. It is understood that... Figure 6B The display panel 10 is shown only schematically, and the actual shape, size, position, and structure of these components are not subject to change. Figure 6B As defined in the accompanying drawings below. Furthermore, the display panel 10 may include more or fewer structures.

[0143] For example, the display body 10a can be used for display, touch control, and electrical connection with a circuit board. The first adhesive layer 10b can serve an adhesive function. The film layer 10c can be made of polyethylene terephthalate (PET) or polyimide (PI), and the film layer 10c can provide support for the display body 10a.

[0144] Figure 6C yes Figure 3 A partial cross-sectional view of one embodiment of the display module 100 at the BB line is shown. Figure 3 .

[0145] like Figure 6C As shown, exemplarily, the protective element 30 may include a protective layer 31 and a connecting layer 32. It will be understood that... Figure 6C The protective element 30 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 6C And the limitations of the accompanying figures below.

[0146] For example, the protective layer 31 may be made of PET material, colorless polyimide (CPI) or ultra-thin glass (UTG).

[0147] It is understood that the protective layer 31 can absorb the energy from the display module 100 being squeezed or impacted, and the protective element 30 can protect the display panel 10. In other embodiments, the protective element 30 may also be made of other materials.

[0148] For example, the bonding layer 32 may be made of optically clear adhesive (OCA). It is understood that the bonding layer 32 serves both light transmission and adhesion purposes. In other embodiments, the bonding layer 32 may also be made of other materials.

[0149] For example, along the Z-axis direction, the protective layer 31 and the connecting layer 32 can be arranged alternately, and the protective layers 31 can be connected to each other through the connecting layer 32. On the side closer to the display panel 10, the protective layer 31 of the protective member 30 can be fixedly connected to the display panel 10. On the side farther from the display panel 10, the protective layer 31 of the protective member 30 can come into contact with the external environment of the display module 100.

[0150] For example, the protective element 30 may include four protective layers 31 and three connecting layers 32. The four protective layers 31 and the three connecting layers 32 may be arranged alternately, and the first layer and the seventh layer may both be protective layers 31.

[0151] For example, the connecting layers 32 may have different thicknesses. The thickness of each connecting layer 32 may not be the same. Figure 6C The thickness relationship between the connecting layer 32 and the protective layer 31 is only schematically shown in the figures and is not actually limited by the figures in this application.

[0152] Understandable, Figure 6C The number of protective layers 31 and connecting layers 32 are shown only schematically; the number of protective layers 31 and connecting layers 32 is not subject to change. Figure 6C Limitations. In other embodiments, the number of protective layers 31 and connecting layers 32 can be other numbers, and the protective element 30 can include more or fewer layers. For example, when the protective element 30 includes more layers, it can include six protective layers 31 and five connecting layers 32. When the protective element 30 includes fewer layers, it can include two protective layers 31 and one connecting layer 32. Specifically, this application does not limit the specific implementation.

[0153] Figure 6D yes Figure 3 A partial cross-sectional view of one embodiment of the display module 100 at the BB line is shown. Figure 4 . Figure 7 yes Figure 5 The support member 20 shown is partially exploded in one embodiment. Figure 1 .

[0154] like Figure 6D and Figure 7 As shown, exemplarily, along the second direction, the support member 20 may include a multilayer fiber layer 21 stacked together.

[0155] For example, the multilayer fiber layer 21 includes a composite layer 22, a first single layer 23, and a second single layer 24. The first single layer 23 may be located on one side of the composite layer 22, and the second single layer 24 may be located on the side of the composite layer 22 away from the first single layer 23. It is understood that the composite layer 22 refers to a fiber layer composed of at least two different types of fibers. A single layer refers to a fiber layer composed of only one type of fiber.

[0156] like Figure 6D As shown, exemplarily, the support member 20 may further include a second adhesive layer 25. The second adhesive layer 25 may be double-sided PI tape; in other words, both sides of the second adhesive layer 25 may have an adhesive function. In other embodiments, the second adhesive layer 25 may also be made of other materials.

[0157] For example, the second adhesive layer 25 may be located on the side of the first single layer 23 away from the composite layer 22 and fixedly connected to the first single layer 23.

[0158] like Figure 6A and Figure 6D As shown, the second adhesive layer 25 can also be fixedly connected to the display panel 10. The support member 20 can be fixedly connected to the display panel 10 through the second adhesive layer 25.

[0159] First implementation method: Please refer to Figure 7 and combined Figure 5 As shown, exemplarily, the modulus of the composite layer 22 in the region of the first bending portion 20b can be a first modulus. The modulus of the composite layer 22 in the region of the first fixing portion 20a can be a second modulus. The modulus of the composite layer 22 in the region of the second fixing portion 20c can be a third modulus. The modulus can be the elastic modulus or Young's modulus.

[0160] For example, both the second and third moduli can be greater than the first moduli.

[0161] It is understandable that by setting both the second and third moduli to be greater than the first modulus, the composite layer 22 at the first bending portion 20b (see [reference]) Figure 5 The lower modulus in the region of the composite layer 22 in the first bending portion 20b makes it less likely to affect the bending performance of the display module 100. Furthermore, the composite layer 22 in the first fixing portion 20a (see [reference]) has a lower modulus, making it less likely to affect the bending performance of the display module 100. Figure 5 The area and composite layer 22 of the second fixing part 20c (see also) Figure 5 The modulus of the area is relatively high, and the first fixing part 20a of the support member 20 is attached to the display module 100 (see [reference]). Figure 3 Part 100a (see also) Figure 3The support and second fixing part 20c of the display module 100 are used for the third part 100c (see also) Figure 3 The support of the components is good, and the flatness of the first part 100a and the third part 100c of the display module 100 is high. The display panel 10 (see [link]) Figure 5 The first display area 11 and the third display area 13 (see also) Figure 5 The lighting and shadows are better. In this way, the display module 100 can balance good bending performance and high flatness, resulting in a better user experience and visual experience.

[0162] For example, the first modulus can be in the range of 220 GPa (gigapascals) to 250 GPa. For instance, the first modulus can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0163] Understandably, by setting the first modulus to within the range of 220Gpa to 250Gpa, the first modulus is relatively low, and the modulus of the composite layer 22 in the first bending portion 20b is also relatively low. This makes it less likely to affect the bending performance of the composite layer 22 in the area of ​​the first bending portion 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0164] In other embodiments, the first modulus may also satisfy other ranges. This application does not specifically limit the specific implementation.

[0165] In some implementations, the second modulus can be in the range of 350 GPa to 400 GPa. For example, the second modulus can be equal to 350 GPa, 360 GPa, 370 GPa, 388 GPa, 399 GPa, or 400 GPa.

[0166] It is understandable that by setting the second modulus in the range of 350Gpa to 400Gpa, the second modulus is higher, the modulus of the composite layer 22 in the first fixing part 20a is higher, the first fixing part 20a of the support member 20 provides better support for the first part 100a of the display module 100, the flatness of the first part 100a of the display module 100 is higher, the light and shadow of the first display area 11 of the display panel 10 is better, and the user's visual experience is better.

[0167] In some implementations, the second modulus may also be in the range of 700 GPa to 1000 GPa. For example, the second modulus may be equal to 700 GPa, 750 GPa, 800 GPa, 888 GPa, 900 GPa, or 1000 GPa.

[0168] It is understandable that by setting the second modulus in the range of 700Gpa to 1000Gpa, the second modulus is higher, the modulus of the composite layer 22 in the first fixing part 20a is higher, the first fixing part 20a of the support member 20 provides better support for the first part 100a of the display module 100, the flatness of the first part 100a of the display module 100 is higher, the light and shadow of the first display area 11 of the display panel 10 is better, and the user's visual experience is better.

[0169] In other embodiments, the second modulus may also satisfy other ranges. This application does not specifically limit the specific implementation.

[0170] In some implementations, the third modulus can be in the range of 350 GPa to 400 GPa. For example, the third modulus can be equal to 350 GPa, 360 GPa, 370 GPa, 388 GPa, 399 GPa, or 400 GPa.

[0171] It is understandable that by setting the third modulus in the range of 350Gpa to 400Gpa, the third modulus is higher, the modulus of the composite layer 22 in the second fixing part 20c is higher, the second fixing part 20c of the support member 20 provides better support for the third part 100c of the display module 100, the flatness of the third part 100c of the display module 100 is higher, the light and shadow of the third display area 13 of the display panel 10 is better, and the user's visual experience is better.

[0172] In some implementations, the third modulus may also be in the range of 700 GPa to 1000 GPa. For example, the third modulus may be equal to 700 GPa, 750 GPa, 800 GPa, 888 GPa, 900 GPa, or 1000 GPa.

[0173] It is understandable that by setting the third modulus in the range of 700Gpa to 1000Gpa, the third modulus is higher, the modulus of the composite layer 22 in the second fixing part 20c is higher, the second fixing part 20c of the support member 20 provides better support for the third part 100c of the display module 100, the flatness of the third part 100c of the display module 100 is higher, the light and shadow of the third display area 13 of the display panel 10 is better, and the user's visual experience is better.

[0174] In other implementations, the third modulus may also satisfy other ranges. This application does not specifically limit the application to these ranges.

[0175] For example, the difference between the first modulus and the second modulus can be greater than or equal to 50 GPa. For instance, the difference between the first modulus and the second modulus can be equal to 50 GPa, 66 GPa, 70 GPa, 88 GPa, or 100 GPa, etc.

[0176] Understandably, by setting the difference between the first modulus and the second modulus to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the first bending portion 20b of the support member 20 is low, resulting in good bending performance. Simultaneously, it ensures that the modulus of the first fixing portion 20a of the support member 20 is high, leading to better support. In this way, the display module 100 can balance good bending performance and high flatness, resulting in a better user experience and visual experience.

[0177] In other embodiments, the difference between the first modulus and the second modulus may also satisfy other ranges. This application does not specifically limit the range.

[0178] For example, the difference between the first modulus and the third modulus can be greater than or equal to 50 GPa. For instance, the difference between the first modulus and the third modulus can be equal to 50 GPa, 66 GPa, 70 GPa, 88 GPa, or 100 GPa, etc.

[0179] Understandably, by setting the difference between the first and third moduli to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the first bending portion 20b of the support member 20 is low, resulting in good bending performance. Simultaneously, it ensures that the modulus of the second fixing portion 20c of the support member 20 is high, leading to better support. In this way, the display module 100 can balance good bending performance and high flatness, resulting in a better user experience and visual experience.

[0180] In other embodiments, the difference between the first modulus and the third modulus may also satisfy other ranges. This application does not specifically limit the range.

[0181] Please see Figure 7 and combined Figure 5 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can be in the range of -10° to 10°. For example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0182] Please see Figure 7 and combined Figure 5As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can be in the range of -10° to 10°. For example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0183] in, Figure 7 The fiber arrangement direction is illustrated with dashed lines in the appendix below. A positive angle indicates that the angle between the fiber arrangement direction and a third direction (i.e., the positive direction of the Y-axis) opens towards both the first direction (i.e., the positive direction of the X-axis) and the third direction. A negative angle indicates that the angle between the fiber arrangement direction and a third direction opens towards both the third direction and the fourth direction (i.e., the negative direction of the X-axis). It is understood that the meaning of positive or negative angle values ​​is the same in the following text and will not be elaborated further.

[0184] In other embodiments, a positive angle can also represent that the opening of the angle between the fiber arrangement direction and a third direction simultaneously faces both the third and fourth directions. A negative angle can also represent that the opening of the angle between the fiber arrangement direction and a third direction simultaneously faces both the first and third directions. Specific implementation can be flexible and tailored to actual needs; this application does not impose any limitations.

[0185] It is understandable that by setting the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing part 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, and the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing part 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, all within the range of -10° to 10°, the fiber arrangement directions of the composite layer 22 in the region of the first fixing part 20a, the region of the first bending part 20b, and the region of the second fixing part 20c can be approximately parallel. This simplifies the processing of the composite layer 22 and makes it easier to process fiber layers using different materials in the regions of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c.

[0186] In other embodiments, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, and the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, can satisfy other ranges. Specifically, this application does not limit it.

[0187] Please see Figure 7 and combined Figure 5 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing part 20a and the third direction is defined as the first angle. The first angle can be in the range of -10° to 10°. For example, the first angle can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0188] Please see Figure 7 and combined Figure 5 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b and the third direction is defined as the second angle. The second angle can be in the range of -10° to 10°. For example, the second angle can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0189] Please see Figure 7 and combined Figure 5 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing part 20c and the third direction is defined as the third angle. The third angle can be in the range of -10° to 10°. For example, the third angle can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0190] Understandably, by setting the first, second, and third angles to be all within the range of -10° to 10°, the angles between the fiber arrangement direction of the composite layer 22 in the first fixing part 20a region, the fiber arrangement direction of the composite layer 22 in the first bending part 20b region, and the fiber arrangement direction of the composite layer 22 in the second fixing part 20c region and the third direction are all relatively small. This ensures that the modulus of the composite layer 22 in the first bending part 20b region is relatively small, which is less likely to affect the bending performance of the composite layer 22, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience. In addition, by setting the first, second, and third angles to be all within the range of -10° to 10°, the processing technology of the composite layer 22 is simpler, and it is easier to process fiber layers using different materials in the regions of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c.

[0191] Please see Figure 7 and combined Figure 5 As shown, by way of example, when the angles between the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a, the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, and the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c and the third direction are all equal to 0°, the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a, the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, and the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c can be approximately parallel to the third direction.

[0192] In other embodiments, the first angle, the second angle, and the third angle can all satisfy other ranges. This application does not specifically limit the scope.

[0193] For example, the composite layer 22 in the region of the first bend 20b may be made of T300 carbon fiber or T700 carbon fiber.

[0194] For example, T300 carbon fiber refers to a specific grade or type of carbon fiber. Carbon fiber refers to a new type of fibrous material with high strength and high modulus, containing more than 90% carbon. T300 carbon fiber can approximately include 93.68% carbon and 5.964% nitrogen. T300 carbon fiber has a core-sheath structure, poor structural uniformity, and weak orientation of graphite microcrystals. T300 carbon fiber deforms significantly under external force and has a low modulus. In one embodiment, the modulus of T300 carbon fiber is approximately 230 GPa. It is understood that T is a designation for a carbon fiber product series, and 93.68% and 5.964% refer to mass percentages. The same symbols with the same meaning will not be repeated hereafter.

[0195] Understandably, a core-skin structure typically refers to a special fibrous structure where the fiber consists of an outer "skin" and an inner "core." Graphite crystallites are tiny crystalline structures formed by carbon atoms arranged in a hexagonal grid. The degree of orientation of graphite crystallites reflects the consistency of their orientation within the material. A higher degree of orientation means that these graphite crystallites are more neatly arranged in a specific direction.

[0196] For example, T700 carbon fiber refers to a specific grade or type of carbon fiber. T700 carbon fiber generally comprises approximately 95.58% carbon and 4.24% nitrogen. Compared to T300 carbon fiber, T700 carbon fiber has a weaker core-sheath structure, improved structural uniformity, and a higher degree of graphite crystal orientation. T700 carbon fiber exhibits reduced deformation under external forces and has a higher modulus. In one embodiment, the modulus of T700 carbon fiber is approximately 240 GPa.

[0197] Understandably, T300 or T700 carbon fiber has a lower modulus, and the composite layer 22 has a lower modulus in the first bending portion 20b. This makes it less likely to affect the bending performance of the composite layer 22 in the area of ​​the first bending portion 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0198] In other embodiments, the composite layer 22 may also be made of other materials in the region of the first bend 20b. This application does not specifically limit the application to these materials.

[0199] For example, the composite layer 22 in the region of the first fixing part 20a may be made of M40 carbon fiber or mesophase pitch-based carbon fiber.

[0200] For example, M40 carbon fiber refers to a specific grade or type of carbon fiber. M40 carbon fiber typically comprises 99.12% carbon and 0.074% nitrogen. Compared to T700 carbon fiber, M40 carbon fiber has a less pronounced core-sheath structure, improved structural uniformity, and a higher degree of graphite crystal orientation. M40 carbon fiber exhibits reduced deformation under external forces and has a higher modulus. In one embodiment, the modulus of M40 carbon fiber is approximately 370 GPa. It is understood that "M" represents a carbon fiber product series designation. This meaning will not be repeated hereafter.

[0201] For example, mesophase pitch-based carbon fiber refers to a specific grade or type of carbon fiber. Mesophase pitch-based carbon fiber may comprise approximately 92% carbon. Compared to M40 carbon fiber, mesophase pitch-based carbon fiber has a cross-section with a large number of curved plate-like crystal structures, improved structural uniformity, higher orientation of graphite crystals, and more regular arrangement of graphite crystals. This results in reduced deformation under external force and a higher modulus. In one embodiment, the modulus of mesophase pitch-based carbon fiber is approximately 800 GPa.

[0202] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a high modulus, the composite layer 22 has a high modulus in the first fixing part 20a, the first fixing part 20a of the support member 20 has high rigidity, the first fixing part 20a of the support member 20 has good support for the first part 100a of the display module 100, the first part 100a of the display module 100 has high flatness, the first display area 11 of the display panel 10 has better light and shadow, and the user's visual experience is better.

[0203] In other embodiments, the composite layer 22 may also be made of other materials in the region of the first fixing portion 20a. This application does not specifically limit the application to these materials.

[0204] For example, the composite layer 22 in the region of the second fixing part 20c may be made of M40 carbon fiber or mesophase pitch-based carbon fiber.

[0205] It is understandable that M40 carbon fiber or mesophase pitch-based carbon fiber has a high modulus, the composite layer 22 has a high modulus in the second fixing part 20c, the second fixing part 20c of the support member 20 has high rigidity, the second fixing part 20c of the support member 20 provides good support for the third part 100c of the display module 100, the third part 100c of the display module 100 has high flatness, the third display area 13 of the display panel 10 has better light and shadow, and the user's visual experience is better.

[0206] In other embodiments, the composite layer 22 may also be made of other materials in the region of the second fixing part 20c. This application does not specifically limit the application to these materials.

[0207] In some embodiments, the angle between the fiber arrangement direction of the first single layer 23 in the region of the first bend 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b is α, where α can satisfy: -90°<a≤-20°. For example, α can be equal to -85°, -70°, -60°, -45°, -30°, or -20°, etc.

[0208] It is understandable that by setting the range of angle α between the fiber arrangement direction of the first single layer 23 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0209] In other implementations, 'a' can satisfy: 20° ≤ a < 90°. For example, 'a' can be equal to 20°, 30°, 45°, 60°, 70°, or 85°, etc.

[0210] It is understandable that by setting the range of angle α between the fiber arrangement direction of the first single layer 23 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support to support the second display area 12 of the display panel 10.

[0211] In other embodiments, the fiber arrangement direction of the first single layer 23 in the region of the first bend 20b may be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b.

[0212] For example, the fiber arrangement direction of the first single layer 23 in the region of the first fixing part 20a, the fiber arrangement direction of the first single layer 23 in the region of the second fixing part 20c, and the fiber arrangement direction of the first single layer 23 in the region of the first bending part 20b can all be the same.

[0213] It is understood that the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the first fixing part 20a. The first fixing part 20a can have high rigidity, thus providing sufficient support for the first display area 11 of the display panel 10. Similarly, the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the second fixing part 20c. The second fixing part 20c can have high rigidity, thus providing sufficient support for the third display area 13 of the display panel 10.

[0214] For example, the modulus of the first monolayer 23 can be in the range of 220 GPa to 250 GPa. For instance, the modulus of the first monolayer 23 can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0215] Understandably, the first single layer 23 has a lower modulus, so it is less likely to affect the bending performance of the first bending part 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0216] In other embodiments, the modulus of the first single layer 23 may also satisfy other ranges. This application does not specifically limit the application.

[0217] For example, the first single layer 23 may be made of T300 carbon fiber or T700 carbon fiber.

[0218] Understandably, T300 or T700 carbon fiber has a lower modulus, and the first single layer 23 has a lower modulus in the first bending portion 20b, which is less likely to affect the bending performance of the composite layer 22 in the area of ​​the first bending portion 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0219] In other embodiments, the first single layer 23 may also be made of other materials. This application does not specifically limit the application to these materials.

[0220] In some embodiments, the angle between the fiber arrangement direction of the second single layer 24 in the region of the first bend 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b is b, and b can satisfy: -90° < b ≤ -20°. For example, b can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0221] It is understandable that by setting the range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0222] In other implementations, b can satisfy: 20°≤b<90°, for example, b can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0223] It is understandable that by setting the range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0224] In other embodiments, the fiber arrangement direction of the second single layer 24 in the region of the first bend 20b may be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b.

[0225] For example, the fiber arrangement direction of the second single layer 24 in the region of the first fixing part 20a, the fiber arrangement direction of the second single layer 24 in the region of the second fixing part 20c, and the fiber arrangement direction of the second single layer 24 in the region of the first bending part 20b can all be the same.

[0226] It is understood that the second single layer 24 and the composite layer 22 can be arranged alternately in the region of the first fixing part 20a. The first fixing part 20a can have high rigidity, thus providing sufficient support for the first display area 11 of the display panel 10. Similarly, the second single layer 24 and the composite layer 22 can be arranged alternately in the region of the second fixing part 20c. The second fixing part 20c can have high rigidity, thus providing sufficient support for the third display area 13 of the display panel 10.

[0227] For example, the modulus of the second monolayer 24 can be in the range of 220 GPa to 250 GPa. For instance, the modulus of the second monolayer 24 can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0228] Understandably, the second single layer 24 has a lower modulus, and therefore the second single layer 24 is less likely to affect the bending performance of the first bending part 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0229] In other embodiments, the modulus of the second single layer 24 may also satisfy other ranges. This application does not specifically limit the application.

[0230] For example, the second single layer 24 may be made of T300 carbon fiber or T700 carbon fiber.

[0231] Understandably, T300 or T700 carbon fiber has a lower modulus, and the second single layer 24 has a lower modulus in the first bending portion 20b, which is less likely to affect the bending performance of the composite layer 22 in the area of ​​the first bending portion 20b, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0232] In other embodiments, the second single layer 24 may also be made of other materials. This application does not specifically limit the application to these materials.

[0233] The structure of the display module 100 in some embodiments has been described in detail above with reference to the accompanying drawings. The following section will describe in detail a method for manufacturing the support member 20 with reference to the accompanying drawings.

[0234] Figure 8A This is a partial flowchart illustrating a method for manufacturing a support member 20 according to an embodiment of this application.

[0235] In some embodiments, this application also provides a method for manufacturing a support member 20. This method can be used to manufacture the support member 20 described above, and can also be used to manufacture support members 20 of other structures in other embodiments. This method includes, but is not limited to, steps S110 to S130 provided below, which will be discussed in conjunction with... Figure 5 , Figure 7 and Figure 8A The following describes the steps involved in manufacturing the support component 20:

[0236] Step S110: Spread out the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn sequentially along the first direction. This process can also be called yarn spreading. Yarn spreading is the process of evenly spreading out the fiber yarn.

[0237] For example, along the first direction, the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn are arranged sequentially in the region of the first fixing part 20a, the region of the first bending part 20b, and the region of the second fixing part 20c of the support member 20, and the angle between the arrangement direction of the first type of fiber yarn, the arrangement direction of the second type of fiber yarn, the arrangement direction of the third type of fiber yarn, and the third direction is in the range of -10° to 10°.

[0238] For example, the first type of fiber yarn can be carbon fiber yarn. In one embodiment, the first type of fiber yarn can be a material having a second modulus, such as M40 carbon fiber yarn, mesophase pitch-based carbon fiber yarn, etc. In other embodiments, the first type of fiber yarn can also be other materials.

[0239] For example, the second type of fiber yarn can be carbon fiber yarn. In one embodiment, the second type of fiber yarn can be a material having a first modulus, for example, the second type of fiber yarn can be T300 carbon fiber yarn, T700 carbon fiber yarn, etc. In other embodiments, the second type of fiber yarn can also be other materials.

[0240] For example, the second type of fiber yarn can be carbon fiber yarn. In one embodiment, the third type of fiber yarn can be a material having a second modulus, for example, the third type of fiber yarn can be M40 carbon fiber yarn, mesophase pitch-based carbon fiber yarn, etc. In other embodiments, the third type of fiber yarn can also be other materials.

[0241] In some implementations, the methods for spreading yarn include mechanical spreading, airflow spreading, and ultrasonic spreading.

[0242] For example, the mechanical yarn spreading method can use specific mechanical devices, such as yarn spreading rollers or comb yarn spreading devices, to stretch and comb the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn, so that the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn are spread into a wider, thinner, and more uniform state.

[0243] For example, the airflow spreading method can generate a high-speed airflow, causing the carbon fiber bundle to be dispersed and spread under the action of the airflow. The airflow can be a gas such as compressed air or nitrogen, which is ejected through a specific nozzle or air duct system to form a high-speed airflow field. When the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn enter this airflow field, the impact force and shear force of the airflow will cause the individual fibers in the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn to separate and spread out.

[0244] For example, the ultrasonic yarn spreading method can utilize the high-frequency vibration energy of ultrasound to subject fiber yarns to minute and rapid mechanical vibrations in a specific device. This vibration can break the adhesion and entanglement between the first, second, and third types of fiber yarns, causing them to gradually spread out into a wider, thinner, and more uniform state.

[0245] Understandably, one can flexibly choose the appropriate yarn unfolding method based on actual needs and conditions.

[0246] Other methods for yarn spreading include electrostatic yarn spreading. This application does not specifically limit the method.

[0247] Step S120: Process the spread-out first-type fiber yarn, second-type fiber yarn, and third-type fiber yarn to form a composite fiber prepreg, also known as prepreg. The prepreg is formed by pressing and impregnating fiber yarns with resin-impregnated release paper to create the fiber prepreg.

[0248] In some embodiments, a suitable resin can be selected according to the performance requirements of the fiber prepreg and manufactured according to a specific formula. The fiber yarn, after the unfolding process, is prepregped with resin to ensure it is fully impregnated. The prepregned fiber yarn is then cured to form a fiber prepreg with a certain strength and / or stiffness.

[0249] For example, a first type of fiber yarn, a second type of fiber yarn, and a third type of fiber yarn are pre-impregnated with resin, such that the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn are fully impregnated in the resin. The pre-impregnated first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn are then cured to form a composite fiber prepreg fabric.

[0250] For example, the resin can be materials such as asphalt or polyacrylonitrile. In other embodiments, the resin can be other types of materials.

[0251] Step S130: Process the composite fiber prepreg to form composite layer 22. Exemplarily, the composite fiber prepreg can be formed into the shape of composite layer 22 by means of hot pressing, cutting, etc.

[0252] In some implementations, the composite fiber prepreg can be subjected to hot pressing, cutting, and other treatments according to actual product requirements, thereby obtaining, for example... Figure 7 The composite layer 22 shown.

[0253] For example, the fabrication of support member 20 also includes the following steps:

[0254] The first single layer 23 is fabricated. In one embodiment, the second type of fiber yarn is uniformly spread out along a first direction, and the angle between the arrangement direction of the second type of fiber yarn in the first single layer 23 and the arrangement direction of the second type of fiber yarn in the composite layer 22 can be in the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the first single layer 23 can be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer 22. The spread-out second type of carbon fiber is pre-impregnated with resin, so that the second type of carbon fiber is fully impregnated with resin, and the pre-impregnated second type of fiber yarn is cured to form a second type of fiber pre-impregnated fabric. After hot pressing and cutting the second type of fiber pre-impregnated fabric, a second type of fiber pre-impregnated fabric is formed as shown in the figure. Figure 7 The first single layer 23 is shown. The first single layer 23 is then stacked on the composite layer 22. For specific steps, please refer to the above description of the fabrication method of the composite layer 22, which will not be repeated here.

[0255] A second single layer 24 is fabricated. In one embodiment, the second type of fiber yarn is uniformly spread out along a first direction, and the angle between the arrangement direction of the second type of fiber yarn in the second single layer 24 and the arrangement direction of the second type of fiber yarn in the composite layer 22 can be in the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the second single layer 24 can be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer 22. The spread-out second type of carbon fiber is pre-impregnated with resin, so that the second type of carbon fiber is fully impregnated with resin, and the pre-impregnated second type of fiber yarn is cured to form a second type of fiber pre-impregnated fabric. After hot pressing and cutting the second type of fiber pre-impregnated fabric, a fabric is formed as shown in the figure. Figure 7 The second single layer 24 is shown. The second single layer 24 is stacked on the side of the composite layer 22 away from the first single layer 23 to form as shown. Figure 5 The support component 20 is shown. For specific steps, please refer to the manufacturing method of composite layer 22 described above; they will not be repeated here.

[0256] In some implementations, the support member 20 can also be manufactured using other manufacturing methods.

[0257] Figure 8B This is a partial flowchart illustrating another method for manufacturing the support member 20 provided in this application embodiment.

[0258] like Figure 8B As shown, exemplarily, a method for manufacturing a support member 20 may include the following steps:

[0259] Step S210: Spread out the first type of fiber yarn, impregnate the spread-out first type of fiber yarn with the first type of resin, and cure the impregnated first type of fiber yarn to form a first type of fiber prepreg fabric. The first type of resin can be asphalt, etc.

[0260] Step S220: Lay out the second type of fiber yarn, impregnate the laid-out second type of fiber yarn with the second type of resin, and cure the impregnated second type of fiber yarn to form a second type of fiber prepreg fabric. The second type of resin can be polyacrylonitrile, etc.

[0261] Step S230: Lay out the third type of fiber yarn, impregnate the laid-out third type of fiber yarn with the third type of resin, and cure the impregnated third type of fiber yarn to form a third type of fiber prepreg. The third type of resin can be asphalt, etc.

[0262] Step S240: The first type of fiber prepreg, the second type of fiber prepreg, and the third type of fiber prepreg are arranged sequentially along the first direction in the regions of the first fixing portion 20a, the first bending portion 20b, and the second fixing portion 20c of the support member 20, and processed to form a composite layer 22. Exemplarily, the first type of fiber prepreg, the second type of fiber prepreg, and the third type of fiber prepreg can be formed by hot pressing and cutting. The angles between the arrangement directions of the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn and the third direction are within the range of -10° to 10°.

[0263] For example, the fabrication of support member 20 also includes the following steps:

[0264] The first single layer 23 is fabricated. In one embodiment, the second type of fiber yarn is uniformly spread out along a first direction, and the angle between the arrangement direction of the second type of fiber yarn in the first single layer 23 and the arrangement direction of the second type of fiber yarn in the composite layer 22 can be in the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the first single layer 23 can be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer 22. The spread-out second type of carbon fiber is pre-impregnated with the second type of resin, so that the second type of carbon fiber and the second type of resin are fully impregnated, and the pre-impregnated second type of fiber yarn is cured to form a second type of fiber pre-impregnated fabric. After hot pressing and cutting the second type of fiber pre-impregnated fabric, a second type of fiber pre-impregnated fabric is formed as shown in the figure. Figure 7 The first single layer 23 is shown. The first single layer 23 is stacked on the composite layer 22.

[0265] A second single layer 24 is fabricated. In one embodiment, the second type of fiber yarn is uniformly spread out along a first direction, and the angle between the arrangement direction of the second type of fiber yarn in the second single layer 24 and the arrangement direction of the second type of fiber yarn in the composite layer 22 can be in the range of greater than -90° and less than or equal to -20°, or greater than or equal to 20° and less than 90°, or the arrangement direction of the second type of fiber yarn in the second single layer 24 can be approximately perpendicular to the arrangement direction of the second type of fiber yarn in the composite layer 22. The spread-out second type of carbon fiber is pre-impregnated with the second type of resin, so that the second type of carbon fiber and the second type of resin are fully impregnated, and the pre-impregnated second type of fiber yarn is cured to form a second type of fiber pre-impregnated fabric. After hot pressing and cutting the second type of fiber pre-impregnated fabric, a fabric is formed as shown in the figure. Figure 7 The second single layer 24 is shown. The second single layer 24 is stacked on the side of the composite layer 22 away from the first single layer 23 to form as shown. Figure 5 The support member 20 shown.

[0266] In other embodiments, the manufacturing method may have more or fewer steps; for example, the manufacturing method may also include steps such as packaging.

[0267] In other embodiments, the support member 20 can also be manufactured using other methods. This application does not specifically limit the method used.

[0268] The preceding text introduced a method for manufacturing the support member 20. The following text, in conjunction with relevant accompanying drawings, will further describe several specific configurations of the display module 100 in some embodiments. It is understood that the design of the display module 100 shown above can be directly applied to the structural design of the display module 100 shown below, provided there is no conflict. Most of the technical content that is the same as that of the display module 100 shown above will not be repeated below.

[0269] Please see Figure 7 and combined Figure 5 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing portion 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b is equal to 0°, and the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can be equal to 0°.

[0270] It is understandable that by setting the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixing part 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, and the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixing part 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, all of which are equal to 0°, the fiber arrangement directions of the composite layer 22 in the region of the first fixing part 20a, the region of the first bending part 20b, and the region of the second fixing part 20c can be approximately parallel. The processing technology of the composite layer 22 is simpler, and it is easier to process fiber layers using different materials in the regions of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c.

[0271] Please see Figure 7 and combined Figure 5 As shown, by way of example, the composite layer 22 can satisfy the following: the first angle can be equal to 0°, the second angle can be equal to 0°, and the third angle can be equal to 0°.

[0272] Understandably, by setting the first, second, and third angles to all 0°, the angles between the fiber arrangement direction of the composite layer 22 in the first fixing part 20a region, the fiber arrangement direction of the composite layer 22 in the first bending part 20b region, and the fiber arrangement direction of the composite layer 22 in the second fixing part 20c region and the third direction are all relatively small. This makes it less likely to affect the bending performance of the composite layer 22, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience. Furthermore, by setting the first, second, and third angles to all 0°, the processing technology of the composite layer 22 is simpler, making it easier to process fiber layers using different materials in the regions of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c.

[0273] In other embodiments, the first angle, the second angle, and the third angle can all satisfy other ranges. This application does not specifically limit the scope.

[0274] Please see Figure 7 and combined Figure 5 As shown, exemplarily, the angle α between the fiber arrangement direction of the first single layer 23 in the region of the first bend 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b is equal to 90°. In other words, the fiber arrangement direction of the first single layer 23 in the region of the first bend 20b can be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b.

[0275] It is understandable that the first single layer 23 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, and while ensuring the bending performance of the first bending portion 20b, it can also have sufficient support, thereby providing sufficient support for the second display area 12 of the display panel 10.

[0276] Please see Figure 7 and combined Figure 5 As shown, by way of example, the fiber arrangement direction of the first single layer 23 in the region of the first fixing portion 20a, the fiber arrangement direction of the first single layer 23 in the region of the second fixing portion 20c, and the fiber arrangement direction of the first single layer 23 in the region of the first bending portion 20b can all be the same. In other words, the fiber arrangement direction of the first single layer 23 in the region of the first fixing portion 20a and the fiber arrangement direction of the first single layer 23 in the region of the second fixing portion 20c can be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b.

[0277] It is understood that the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the first fixing part 20a. The first fixing part 20a can have high rigidity, thus providing sufficient support for the first display area 11 of the display panel 10. Similarly, the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the second fixing part 20c. The second fixing part 20c can have high rigidity, thus providing sufficient support for the third display area 13 of the display panel 10.

[0278] Please see Figure 7 and combined Figure 5 As shown, exemplarily, the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bend 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b is equal to 90°. In other words, the fiber arrangement direction of the second single layer 24 in the region of the first bend 20b can be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bend 20b.

[0279] It is understandable that the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, and while ensuring the bending performance of the first bending portion 20b, it can also have sufficient support, thereby providing sufficient support for the second display area 12 of the display panel 10.

[0280] Please see Figure 7 and combined Figure 5 As shown, by way of example, the fiber arrangement direction of the second single layer 24 in the region of the first fixing portion 20a, the fiber arrangement direction of the second single layer 24 in the region of the second fixing portion 20c, and the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b can all be the same. In other words, the fiber arrangement direction of the second single layer 24 in the region of the first fixing portion 20a and the fiber arrangement direction of the second single layer 24 in the region of the second fixing portion 20c can be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b.

[0281] It is understood that the second single layer 24 and the composite layer 22 can be arranged alternately in the region of the first fixing part 20a. The first fixing part 20a can have high rigidity, thus providing sufficient support for the first display area 11 of the display panel 10. Similarly, the second single layer 24 and the composite layer 22 can be arranged alternately in the region of the second fixing part 20c. The second fixing part 20c can have high rigidity, thus providing sufficient support for the third display area 13 of the display panel 10.

[0282] In this embodiment, the support member 20 has a lower modulus in the first bending portion 20b, while the modulus of the first fixing portion 20a and the second fixing portion 20c are both larger. Without affecting the bending performance of the display module 100, it can provide better support for the first portion 100a and the third portion 100c of the display module 100. The flatness of the first portion 100a and the third portion 100c of the display module 100 is high, and the light and shadow of the first display area 11 and the third display area 13 of the display panel 10 are better. Thus, the user experience and visual experience are both superior.

[0283] Second implementation method: Please refer to Figure 5 and Figure 9 , Figure 9 yes Figure 7 The support member 20 shown is partially exploded in one embodiment. Figure 2 .

[0284] For example, the configuration of the composite layer 22 can be referred to the first embodiment. Specific details will not be elaborated further.

[0285] Please see Figure 9 and combined Figure 5 As shown, by way of example, the first single layer 23 can satisfy: -90°<a≤-20°, for example, a can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0286] It is understandable that by setting the range of angle α between the fiber arrangement direction of the first single layer 23 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0287] In other implementations, 'a' can satisfy: 20° ≤ a < 90°. For example, 'a' can be equal to 20°, 30°, 45°, 60°, 70°, or 85°, etc.

[0288] It is understandable that by setting the range of angle α between the fiber arrangement direction of the first single layer 23 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0289] For example, the fiber arrangement direction of the first single layer 23 in the region of the first fixing part 20a, the fiber arrangement direction of the first single layer 23 in the region of the second fixing part 20c, and the fiber arrangement direction of the first single layer 23 in the region of the first bending part 20b can all be the same.

[0290] It is understood that the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the first fixing part 20a. The first fixing part 20a can have high rigidity, thus providing sufficient support for the first display area 11 of the display panel 10. Similarly, the first single layer 23 and the composite layer 22 can be arranged alternately in the region of the second fixing part 20c. The second fixing part 20c can have high rigidity, thus providing sufficient support for the third display area 13 of the display panel 10.

[0291] Please see Figure 9 and combined Figure 5 As shown, in some embodiments, the second single layer 24 can satisfy: -90° < b ≤ -20°, for example, b can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0292] It is understandable that by setting the range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0293] In other implementations, b can satisfy: 20°≤b<90°, for example, b can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0294] It is understandable that by setting the range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0295] Please see Figure 9 and combined Figure 5 As shown, by way of example, the fiber arrangement direction of the second single layer 24 in the region of the first fixing part 20a, the fiber arrangement direction of the second single layer 24 in the region of the second fixing part 20c, and the fiber arrangement direction of the second single layer 24 in the region of the first bending part 20b can all be the same.

[0296] It is understandable that by setting the range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the first bending portion 20b. In this way, the first bending portion 20b can have high rigidity, ensuring its bending performance while also providing sufficient support, thereby providing adequate support for the second display area 12 of the display panel 10.

[0297] It is understood that other related configurations of the first single layer 23 and the second single layer 24 can be found in the first implementation method. Specific details will not be elaborated further.

[0298] Third implementation method: Please refer to Figure 5 and Figure 10 , Figure 10 yes Figure 7 The support member 20 shown is partially exploded in one embodiment. Figure 3 .

[0299] For example, the arrangement of the composite layer 22 in the region of the first fixing part 20a and the region of the second fixing part 20c can both refer to the relevant scheme of the first embodiment. Specific details will not be elaborated further.

[0300] For example, the composite layer 22 includes a first region 221 and a second region 222 connected sequentially along a first direction in the region of the first bend 20b.

[0301] For example, the modulus of the first region 221 can be a fourth modulus. The modulus of the second region 222 can be a fifth modulus. The fourth modulus and the fifth modulus can be different.

[0302] It is understandable that by setting the fourth and fifth moduli to be different, the modulus of the first region 221 and the modulus of the second region 222 can be different, and the composite layer 22 can simultaneously possess different properties in the region of the first bending portion 20b.

[0303] For example, the fourth modulus may be smaller than the fifth modulus.

[0304] Understandably, the lower modulus of the first region 221 and the lower modulus of the composite layer 22 in the first region 221 make it less likely to affect the bending performance of the composite layer 22 in the first region 221, and thus less likely to affect the display module 100 (see [link]). Figure 5 The bending performance is good, resulting in a better user experience. The second region 222 has a higher modulus, the composite layer 22 has a higher modulus in the second region 222, and the support member 20 in the second region 222 partially supports the second part 100b of the display module 100 (see [reference]). Figure 3 The support is good, the second part 100b of the display module 100 has high flatness, and the second display area 12 of the display panel 10 (see [reference]) has good support. Figure 5 The lighting and shadows are better, resulting in a better visual experience for the user. Thus, the second part 100b of the display module 100 can balance good bending performance and good display effect.

[0305] In other embodiments, the fourth modulus may also be greater than the fifth modulus. This application does not specifically limit the details.

[0306] For example, the number of first regions 221 can be at least two. The number of second regions 222 can be at least one. Along the first direction, at least one second region 222 can be arranged between two first regions 221.

[0307] For example, the first region 221 can be made of T300 carbon fiber or T700 carbon fiber.

[0308] Understandably, T300 carbon fiber or T700 carbon fiber has a lower modulus, and the composite layer 22 has a lower modulus in the first region 221. This makes it less likely to affect the bending performance of the composite layer 22 in the first region 221, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0309] In other embodiments, the first region 221 may also be made of other materials. This application does not specifically limit the application to these materials.

[0310] For example, the second region 222 can be made of M40 carbon fiber or mesophase pitch-based carbon fiber.

[0311] Understandably, M40 carbon fiber or mesophase pitch-based carbon fiber has a higher modulus, the composite layer 22 has a higher modulus in the second region 222, the support member 20 has higher rigidity in the second region 222, and the portion of the support member 20 in the second region 222 corresponds to the second portion 100b of the display module 100 (see [link]). Figure 3 The support is good, the second part 100b of the display module 100 has high flatness, and the second display area 12 of the display panel 10 (see [reference]) has good support. Figure 5 The lighting and shadows are better, resulting in a better visual experience for users.

[0312] In other embodiments, the second region 222 may also be made of other materials. This application does not specifically limit the application to these materials.

[0313] In other embodiments, the composite layer 22 may be woven with a mixture of high-modulus and low-modulus materials in the region of the first bend 20b. In other words, high-modulus fibers and low-modulus fibers may coexist in any region of the first bend 20b of the composite layer 22.

[0314] For example, the composite layer 22 in the region of the first bend 20b may be made of a material woven from at least two of T300 carbon fiber, M40 carbon fiber, T700 carbon fiber, and mesophase pitch-based carbon fiber. In one embodiment, the composite layer 22 in the region of the first bend 20b may be made of a material woven from a mixture of T300 carbon fiber and M40 carbon fiber, a material woven from a mixture of T300 carbon fiber and mesophase pitch-based carbon fiber, a material woven from a mixture of T700 carbon fiber and M40 carbon fiber, or a material woven from a mixture of T700 carbon fiber and mesophase pitch-based carbon fiber. The composite layer 22 in the region of the first bend 20b may also be made of a material woven from a mixture of T300 carbon fiber, T700 carbon fiber and M40 carbon fiber, or a material woven from a mixture of T300 carbon fiber, T700 carbon fiber and mesophase pitch-based carbon fiber, or a material woven from a mixture of T300 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber, or a material woven from a mixture of T700 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber, or a material woven from a mixture of T300 carbon fiber, T700 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber.

[0315] It is understood that the composite layer 22 can simultaneously contain materials with high modulus and materials with low modulus in any region of the first bend 20b, and the composite layer 22 in the region of the first bend 20b is less likely to affect the display module 100 (see [link]). Figure 3 The bending performance of the display module 100 is improved, and the second part 100b of the display module 100 is also improved (see [link]). Figure 3 The flatness of the surface of the second part 100b of the display module 100 is good, and the light and shadow are better, resulting in a better user experience and visual experience.

[0316] In other embodiments, the composite layer 22 may be woven with other materials in the region of the first bend 20b. This application does not specifically limit the application to this method.

[0317] For example, the configuration methods of the first single layer 23 and the second single layer 24 can also be referred to the above-described embodiments. They will not be repeated here. It is understood that, compared to the first embodiment, in this embodiment, without affecting the bending performance of the display module 100, the support member 20 can provide better support for the first part 100a, the second part 100b, and the third part 100c of the display module 100. The flatness of the first part 100a, the second part 100b, and the third part 100c is relatively high, and the light and shadow of the first display area 11, the second display area 12, and the third display area 13 are all good. Thus, the user's experience and visual experience are both better.

[0318] Fourth implementation: It is understood that the electronic device 1000 described above is based on a single fold. In other implementations, the electronic device 1000 may also undergo two or more folds. The technical content that is largely the same as above will not be repeated in this implementation.

[0319] Figure 11 This is a schematic diagram of the electronic device 1000 provided in this application embodiment in a flattened state. Figure 12 yes Figure 11 The diagram shows a structural schematic of one embodiment of the electronic device 1000 in its first folded state. Figure 13 yes Figure 11 The diagram shows a structural schematic of one embodiment of the electronic device 1000 in its second folded state.

[0320] like Figures 11 to 13 As shown, this application provides an electronic device 1000 that can be folded more than once. Figures 11 to 13 The illustrated embodiment of the electronic device 1000 is still described using a mobile phone as an example. For ease of description, exemplarily, the length direction of the electronic device 1000 is defined as the X-axis direction, the thickness direction of the electronic device 1000 is defined as the Z-axis direction, and the extension direction of the rotation axis of the electronic device 1000 is defined as the Y-axis direction, that is, the width direction of the electronic device 1000 is defined as the Y-axis direction. It is understood that the coordinate system of the electronic device 1000 can also be flexibly set according to specific needs. Exemplarily, the positive direction of the X-axis is defined as the first direction, the positive direction of the Z-axis as the second direction, the positive direction of the Y-axis as the third direction, the negative direction of the X-axis as the fourth direction, the negative direction of the Z-axis as the fifth direction, and the negative direction of the Y-axis as the sixth direction. In other embodiments, the first, second, third, fourth, fifth, and sixth directions can also be flexibly set according to needs, as long as the first, second, third, fourth, fifth, and sixth directions are different.

[0321] For example, the rotation axis of the electronic device 1000 can be in the Y-axis direction, and the electronic device 1000 can be unfolded or folded relative to each other along the Y-axis direction. Thus, when the electronic device 1000 is in a folded state, its size in the X-axis direction becomes smaller. In other embodiments, the rotation axis of the electronic device 1000 can also be in other directions.

[0322] Figure 14 yes Figure 11 The illustrated electronic device 1000 is shown in a partially exploded view according to one embodiment. Figure 15 yes Figure 13 A partial cross-sectional view of one embodiment of the electronic device 1000 at the CC line.

[0323] Please see Figure 14 and Figure 15 and combined Figures 11 to 13 As shown, the electronic device 1000 includes a display module 100, a first housing 210, a second housing 220, a third housing 230, a first folding mechanism 310, and a second folding mechanism 320. The first housing 210, second housing 220, third housing 230, first folding mechanism 310, and second folding mechanism 320 can constitute the housing device 300 of the electronic device 1000. The display module 100 can be mounted on the housing device 300, and the housing device 300 can be used to drive the display module 100 to unfold or fold relative to each other. It is understood that... Figure 11 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 11 As well as the figures below. Furthermore, the electronic device 1000 may include more or fewer structures; for example, the electronic device 1000 may also include a camera module (not shown).

[0324] Exemplarily, the first folding mechanism 310 can connect the first housing 210 and the second housing 220. The first folding mechanism 310 can be used to unfold or fold the first housing 210 and the second housing 220 relative to each other. The second folding mechanism 320 can connect the second housing 220 and the third housing 230. The second folding mechanism 320 can be used to unfold or fold the second housing 220 and the third housing 230 relative to each other. It is understood that in this application, by providing the first folding mechanism 310 and the second folding mechanism 320 in the electronic device 1000, the electronic device 1000 can achieve multiple folds. The first folding mechanism 310 can be an inner folding mechanism. The second folding mechanism 320 can be an outer folding mechanism. An inner folding mechanism refers to a folding mechanism that can fold at least a portion of the display module 100 between the two housings. An outer folding mechanism refers to a folding mechanism that can fold at least a portion of the display module 100 outside the housing.

[0325] In other embodiments, the first folding mechanism 310 may also be an outward folding mechanism. The second folding mechanism 320 may also be an inward folding mechanism. This application does not specifically limit the application.

[0326] In this embodiment, the first folding mechanism 310 is an inner folding mechanism and the second folding mechanism 320 is an outer folding mechanism, as an example, for description.

[0327] Please see Figure 14 and combined Figure 11As shown, when the first housing 210, the second housing 220, the third housing 230, the first folding mechanism 310, and the second folding mechanism 320 are unfolded to a flattened state, the electronic device 1000 is in a flattened state. For example, when the electronic device 1000 is in a flattened state, the first housing 210, the second housing 220, the third housing 230, the first folding mechanism 310, and the second folding mechanism 320 can be arranged along the X-axis direction, and can be approximately 180° apart (with slight deviations allowed, such as 165°, 177°, or 185°).

[0328] Please see Figure 12 and combined Figure 14 As shown, when the first housing 210, the second housing 220, the third housing 230, the first folding mechanism 310, and the second folding mechanism 320 are folded relative to each other to the first folded state, the electronic device 1000 is in the first folded state. For example, when the electronic device 1000 is in the first folded state, the first housing 210, the second housing 220, and the first folding mechanism 310 can be arranged along the X-axis direction, and can be approximately 180° apart (allowing slight deviations, such as 165°, 177°, or 185°, etc.). The second housing 220 and the third housing 230 can be close to each other, and the second housing 220 and the third housing 230 can be stacked along the Z-axis direction.

[0329] Please see Figure 15 and combined Figure 13 As shown, when the first housing 210, the second housing 220, the third housing 230, the first folding mechanism 310, and the second folding mechanism 320 are folded relative to each other to a second folded state, the electronic device 1000 is in the second folded state. For example, when the electronic device 1000 is in the second folded state, the first housing 210 and the second housing 220 can be brought close together, and the first housing 210 and the second housing 220 can be stacked in the Z-axis direction; the second housing 220 and the third housing 230 can be brought close together, and the second housing 220 and the third housing 230 can be stacked in the Z-axis direction, with the second housing 220 stacked between the first housing 210 and the third housing 230. At this time, the first housing 210, the second housing 220, and the third housing 230 can be arranged along the Z-axis direction. When the first housing 210 and the second housing 220 change from the first folded state to the second folded state, the first folding mechanism 310 can enclose an accommodating space 3101. It is understood that the first folding mechanism 310 with different structures can have accommodating spaces 3101 with different shapes. This application does not limit the specific structure of the first folding mechanism 310 and the second folding mechanism 320.

[0330] Please see Figure 14 and Figure 15 and combined Figures 11 to 13As shown, the display module 100 includes a first part 100a, a second part 100b, a third part 100c, a fourth part 100d, and a fifth part 100e connected sequentially. The second part 100b can be connected between the first part 100a and the third part 100c. The third part 100c can be connected between the second part 100b and the fourth part 100d. The fourth part 100d can be connected between the third part 100c and the fifth part 100e. For example, Figure 11 and Figure 14 The diagram is illustrated using the arrangement of the first part 100a, the second part 100b, the third part 100c, the fourth part 100d, and the fifth part 100e along the X-axis as an example.

[0331] The first part 100a of the display module 100 can be fixed to the first housing 210. The third part 100c can be fixed to the second housing 220. The fifth part 100e can be fixed to the third housing 230. It is understood that when the first folding mechanism 310 unfolds or folds the first housing 210 relative to the second housing 220, the first housing 210 can cause the first part 100a of the display module 100 to unfold or fold relative to the third part 100c, and the second housing 220 can cause the third part 100c of the display module 100 to unfold or fold relative to the first part 100a. At this time, the second part 100b of the display module 100 can be bent. When the second folding mechanism 320 unfolds or folds the second housing 220 relative to the third housing 230, the second housing 220 can cause the third part 100c of the display module 100 to unfold or fold relative to the fifth part 100e, and the third housing 230 can cause the fifth part 100e of the display module 100 to unfold or fold relative to the third part 100c. At this time, the fourth part 100d of the display module 100 can bend around the third direction.

[0332] like Figure 11 and Figure 14 As shown, when the electronic device 1000 is in a flattened state, the display module 100 can also be in a flattened state. For example, the first portion 100a, the second portion 100b, the third portion 100c, the fourth portion 100d, and the fifth portion 100e of the display module 100 can be approximately 180° (with slight deviations allowed, such as 165°, 177°, or 185°). In this state, the display module 100 can have a continuous, large display area, meaning it can achieve a large-screen display, resulting in a better user experience.

[0333] For example, when the electronic device 1000 is in a flattened state, at least a portion of the first folding mechanism 310 can be used to support the second part 100b, and at least a portion of the second folding mechanism 320 can be used to support the fourth part 100d. Thus, when the second part 100b and the fourth part 100d of the display module 100 are subjected to pressing, squeezing, or impact forces, the first folding mechanism 310 and the second folding mechanism 320 can be used to improve the pressure resistance and impact resistance of the second part 100b and the fourth part 100d, that is, to ensure that the second part 100b and the fourth part 100d are not prone to dents or other problems.

[0334] Please see Figure 12 and combined Figure 11 As shown, when the electronic device 1000 is in the first folded state, the display module 100 can also be in the first folded state. The first portion 100a, second portion 100b, third portion 100c, fourth portion 100d, and fifth portion 100e of the display module 100 can all be located on the outside of the electronic device 1000. At this time, the first portion 100a, second portion 100b, third portion 100c, fourth portion 100d, and fifth portion 100e of the display module 100 are folded to form the outer screen of the electronic device 1000. For example, the first portion 100a, second portion 100b, and third portion 100c of the display module 100 can be approximately 180° (with slight deviations allowed, such as 165°, 177°, or 185°). The third portion 100c and fifth portion 100e of the display module 100 are positioned close to each other. At this time, the third portion 100c and fifth portion 100e of the display module 100 can be arranged along the Z-axis direction. Furthermore, the fourth part 100d of the display module 100 can be bent around a third direction.

[0335] like Figure 13 and Figure 15 As shown, when the electronic device 1000 is in the second folded state, the display module 100 can also be in the second folded state. Exemplarily, the first portion 100a and the third portion 100c of the display module 100 can be arranged close to each other, and the third portion 100c and the fifth portion 100e of the display module 100 can also be arranged close to each other. At this time, the first portion 100a, the third portion 100c, and the fifth portion 100e of the display module 100 can be arranged along the Z-axis direction. Furthermore, the second portion 100b and the fourth portion 100d of the display module 100 can be bent around a third direction.

[0336] For example, when the electronic device 1000 is in the second folded state, the first part 100a, the second part 100b, and the third part 100c of the display module 100 can all be located between the first housing 210 and the second housing 220, and the second part 100b can be located within the accommodating space 3101 of the first folding mechanism 310. The fourth part 100d and the fifth part 100e of the display module 100 can both be located outside the second folding mechanism 320 and the third housing 230 (that is, outside the electronic device 1000), and the fifth part 100e of the display module 100 can be located on the side of the third housing 230 away from the second housing 220. When the electronic device 1000 is in the second folded state, since the first part 100a, the second part 100b, and the third part 100c of the display module 100 can all be located between the first housing 210 and the second housing 220, the display surface of the first part 100a can face the display surface of the third part 100c, the second part 100b can be bent and disposed between the first part 100a and the third part 100c, and the second part 100b can be located within the accommodating space 3101 of the first folding mechanism 310, the first part 100a, the second part 100b, and the third part 100c of the display module 100 can be referred to as the inner screen of the display module 100. When the first housing 210 and the second housing 220 are folded, the first part 100a, the second part 100b, and the third part 100c can be folded into the space formed by the first housing 210, the second housing 220, and the first folding mechanism 310. Therefore, the first part 100a, the second part 100b, and the third part 100c can be referred to as the inner screen of the display module 100. When the second housing 220 and the third housing 230 are folded, at least a portion of the display surface of the fourth part 100d and the display surface of the fifth part 100e of the display module 100 can be located outside the second folding mechanism 320 and the third housing 230, that is, outside the electronic device 1000. Therefore, the fourth part 100d and the fifth part 100e of the display module 100 can be referred to as the outer screen of the display module 100. At this time, the second folding mechanism 320 can be used to fold the fourth part 100d and the fifth part 100e of the display module 100 into the outer screen of the electronic device 1000.

[0337] Figure 16 yes Figure 14 The display module 100 shown is partially exploded in one embodiment.

[0338] like Figure 16As shown, the display panel 10 of the display module 100 includes a first display area 11, a second display area 12, a third display area 13, a fourth display area 14, and a fifth display area 15 connected sequentially along the X-axis. In other words, the second display area 12 can be connected between the first display area 11 and the third display area 13. The fourth display area 14 can be connected between the third display area 13 and the fifth display area 15. It is understood that... Figure 16 The first display area 11, the second display area 12, the third display area 13, the fourth display area 14, and the fifth display area 15 are schematically distinguished by dashed lines. In other embodiments, the first display area 11, the second display area 12, the third display area 13, the fourth display area 14, and the fifth display area 15 may also have other configurations.

[0339] like Figure 16 As shown, along the fourth direction (i.e., the negative direction of the X-axis), the support member 20 includes a first fixing part 20a, a first bending part 20b, a second fixing part 20c, a second bending part 20d, and a third fixing part 20e, which are sequentially connected. In other words, the first bending part 20b can be connected between the first fixing part 20a and the second fixing part 20c. The second bending part 20d can be connected between the second fixing part 20c and the third fixing part 20e, and the support member 20 can be bent at the second bending part 20d. It is understood that although the arrangement direction of each part of the support member 20 is the same as the arrangement direction of each part of the display panel 10, within the range of process errors or tolerances, the arrangement direction of each part of the support member 20 and the arrangement direction of each part of the display panel 10 can be different, that is, they are not strictly parallel. In addition, Figure 16 The first fixing part 20a, the first bending part 20b, the second fixing part 20c, the second bending part 20d, and the third fixing part 20e are schematically distinguished by dashed lines. In other embodiments, the first fixing part 20a, the first bending part 20b, the second fixing part 20c, the second bending part 20d, and the third fixing part 20e may also have other arrangements.

[0340] It is understandable that the structures of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c of the support member 20 can be referred to the structure of the first fixing part 20a, the first bending part 20b, and the second fixing part 20c of the support member 20 of the one-fold electronic device 1000 described above. Specific details will not be repeated here.

[0341] Figure 17 yes Figure 16 The support member 20 shown is partially exploded in one embodiment.

[0342] like Figure 16 and Figure 17As shown, exemplarily, along the second direction, the support member 20 may include a multilayer fiber layer 21 stacked together.

[0343] For example, the multilayer fiber layer 21 includes a composite layer 22, a first single layer 23, and a second single layer 24. It is understood that the arrangement of the composite layer 22 in the region of the first fixing portion 20a, the region of the composite layer 22 in the region of the first bending portion 20b, and the region of the composite layer 22 in the region of the second fixing portion 20c can all be found in the various embodiments described above. Specific details will not be elaborated further.

[0344] Please see Figure 17 and combined Figure 14 and Figure 16 As shown, by way of example, the modulus of the composite layer 22 in the region of the second bending portion 20d can be a sixth modulus. The modulus of the composite layer 22 in the region of the third fixing portion 20e can be a seventh modulus. The seventh modulus can be greater than the sixth modulus.

[0345] Understandably, by setting the seventh modulus to be greater than the sixth modulus, the composite layer 22 has a lower modulus in the region of the second bending portion 20d, which is less likely to affect the bending performance of the composite layer 22 in the region of the second bending portion 20d, and thus less likely to affect the bending performance of the display module 100. Furthermore, the composite layer 22 has a higher modulus in the region of the third fixing portion 20e, resulting in better support for the fifth portion 100e of the display module 100 by the third fixing portion 20e of the support member 20, higher flatness of the fifth portion 100e of the display module 100, and better light and shadow in the fifth display area 15 of the display panel 10. In this way, the display module 100 can achieve both good bending performance and high flatness, resulting in a better user experience and visual experience.

[0346] For example, the sixth modulus can be in the range of 220 GPa to 250 GPa. For instance, the sixth modulus can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0347] Understandably, by setting the sixth modulus in the range of 220Gpa to 250Gpa, the sixth modulus is relatively low, and the modulus of the composite layer 22 in the region of the second bending portion 20d is relatively low, which is less likely to affect the bending performance of the composite layer 22 in the region of the second bending portion 20d, and thus less likely to affect the bending performance of the display module 100.

[0348] In other implementations, the sixth modulus may also satisfy other ranges. This application does not specifically limit the application to these ranges.

[0349] In some implementations, the seventh modulus can be in the range of 350 GPa to 400 GPa. For example, the seventh modulus can be equal to 350 GPa, 360 GPa, 370 GPa, 388 GPa, 399 GPa, or 400 GPa.

[0350] It is understandable that by setting the seventh modulus within the range of 350Gpa to 400Gpa, the seventh modulus is relatively high, the modulus of the composite layer 22 in the region of the third fixing part 20e is relatively high, the rigidity of the third fixing part 20e of the support member 20 is relatively high, the third fixing part 20e of the support member 20 provides good support for the fifth display area 15 of the display panel 10, the flatness of the fifth part 100e of the display module 100 is relatively high, the light and shadow of the fifth part 100e of the display module 100 is relatively good, and the user's visual experience is better.

[0351] In some implementations, the seventh modulus can be in the range of 700 GPa to 1000 GPa. For example, the seventh modulus can be equal to 700 GPa, 750 GPa, 800 GPa, 888 GPa, 900 GPa, or 1000 GPa.

[0352] It is understandable that by setting the seventh modulus in the range of 700Gpa to 1000Gpa, the seventh modulus is relatively high, the modulus of the composite layer 22 in the area of ​​the third fixing part 20e is relatively high, the third fixing part 20e of the support member 20 provides good support for the fifth display area 15 of the display panel 10, the flatness of the fifth part 100e of the display module 100 is relatively high, the light and shadow of the fifth part 100e of the display module 100 is relatively good, and the user's visual experience is better.

[0353] In other implementations, the seventh modulus may also satisfy other ranges. This application does not specifically limit the specific implementation.

[0354] For example, the difference between the seventh modulus and the sixth modulus can be greater than or equal to 50 GPa. For instance, the difference between the seventh modulus and the sixth modulus can be equal to 50 GPa, 66 GPa, 70 GPa, 88 GPa, or 100 GPa, etc.

[0355] Understandably, by setting the difference between the seventh and sixth moduli to be greater than or equal to 50 GPa, it is possible to ensure that the modulus of the second bending portion 20d of the support member 20 is low, resulting in good bending performance. Simultaneously, it ensures that the modulus of the third fixing portion 20e of the support member 20 is high, resulting in high rigidity and good support. In this way, the display module 100 can achieve a balance between good bending performance and high flatness, leading to a better user experience and visual experience.

[0356] In other embodiments, the difference between the seventh modulus and the sixth modulus may also satisfy other ranges. This application does not specifically limit the range.

[0357] Please see Figure 17 and combined Figure 16 As shown, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e can be in the range of -10° to 10°. For example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0358] It is understandable that by setting the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e to be within the range of -10° to 10°, the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e can be approximately parallel. The processing technology of the composite layer 22 is simpler, and it is easier to process fiber layers using different materials in the regions of the second bending portion 20d and the third fixing portion 20e.

[0359] Please see Figure 17 and combined Figure 16 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d and the third direction is defined as the fourth angle. The fourth angle can be in the range of -10° to 10°. For example, the fourth angle can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0360] Please see Figure 17 and combined Figure 16 As shown, by way of example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the third fixing part 20e and the third direction is defined as the fifth angle. The fifth angle can be in the range of -10° to 10°. For example, the fifth angle can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0361] Understandably, by setting both the fourth and fifth angles within the range of -10° to 10°, the angles between the fiber arrangement direction of the composite layer 22 in the second bending portion 20d region and the fiber arrangement direction of the composite layer 22 in the third fixing portion 20e region and the third direction are both smaller. This makes it less likely to affect the bending performance of the composite layer 22, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience. Furthermore, by setting both the fourth and fifth angles within the range of -10° to 10°, the processing technology of the composite layer 22 is simpler, making it easier to process fiber layers using different materials in the second bending portion 20d and the third fixing portion 20e regions.

[0362] Please see Figure 17 and combined Figure 16 As shown, by way of example, when the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e and the third direction is equal to 0°, the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e can be approximately parallel to the third direction.

[0363] It is understandable that the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixing portion 20e are roughly parallel to the third direction, which does not easily affect the bending performance of the composite layer 22 in the region of the second bending portion 20d, and thus does not easily affect the bending performance of the display module 100, resulting in a better user experience.

[0364] In other embodiments, the fourth and fifth angles can satisfy other ranges. This application does not specifically limit the scope.

[0365] For example, the composite layer 22 in the region of the second bend 20d can be made of T300 carbon fiber or T700 carbon fiber.

[0366] Understandably, T300 or T700 carbon fiber has a lower modulus, and the composite layer 22 has a lower modulus in the second bending portion 20d. This makes it less likely to affect the bending performance of the composite layer 22 in the area of ​​the second bending portion 20d, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0367] In other embodiments, the composite layer 22 may also be made of other materials in the region of the second bend 20d. This application does not specifically limit the application to these materials.

[0368] For example, the composite layer 22 in the region of the third fixing part 20e may be made of mesophase pitch-based carbon fiber or M40 carbon fiber.

[0369] Understandably, the mesophase pitch-based carbon fiber or M40 carbon fiber has a higher modulus, the composite layer 22 has a higher modulus in the third fixing part 20e, the third fixing part 20e of the support member 20 has higher rigidity, and the third fixing part 20e of the support member 20 provides better support for the fifth part 100e of the display module 100. (See also: [link to relevant documentation]) Figure 14 The flatness of the panel is relatively high, the light and shadow of the fifth display area 15 of the display panel 10 are better, and the user's visual experience is better.

[0370] In other embodiments, the composite layer 22 may also be made of other materials in the region of the third fixing part 20e. This application does not specifically limit the application to these materials.

[0371] For example, the arrangement of the first single layer 23 in the region of the first fixing portion 20a, the region of the first bending portion 20b, and the region of the second fixing portion 20c can all refer to the relevant solutions of the embodiments described above. The arrangement of the second single layer 24 in the regions of the first fixing portion 20a, the region of the first bending portion 20b, and the region of the second fixing portion 20c can also refer to the relevant solutions of the embodiments described above. Specific details will not be elaborated further.

[0372] Please see Figure 17 and combined Figure 16 As shown, by way of example, the angle between the fiber arrangement direction of the first single layer 23 in the region of the second bend 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d is c, and c can satisfy: -90°<c≤-20°. For example, c can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0373] It is understandable that by setting the range of the angle c between the fiber arrangement direction of the first single layer 23 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the second bending portion 20d. In this way, the second bending portion 20d can have high rigidity, ensuring its bending performance while also providing sufficient support to support the fourth display area 14 of the display panel 10.

[0374] In other implementations, c can satisfy: 20°≤c<90°, for example, c can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0375] It is understandable that by setting the range of the angle c between the fiber arrangement direction of the first single layer 23 in the region of the second bending portion 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bending portion 20d, the first single layer 23 and the composite layer 22 are arranged alternately in the region of the second bending portion 20d. In this way, the second bending portion 20d can have high rigidity, ensuring its bending performance while also providing sufficient support to support the fourth display area 14 of the display panel 10.

[0376] In other embodiments, the fiber arrangement direction of the first single layer 23 in the region of the second bend 20d may be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d.

[0377] Please see Figure 17 and combined Figure 16 As shown, by way of example, the fiber arrangement direction of the first single layer 23 in the region of the third fixing part 20e may be the same as the fiber arrangement direction of the first single layer 23 in the region of the second bending part 20d.

[0378] It is understandable that the first single layer 23 in the region of the third fixing part 20e and the composite layer 22 in the region of the third fixing part 20e can be arranged alternately. The third fixing part 20e can have high rigidity, thereby having sufficient support and providing sufficient support performance for the fifth display area 15 of the display panel 10.

[0379] For example, the modulus of the first monolayer 23 can be in the range of 220 GPa to 250 GPa. For instance, the modulus of the first monolayer 23 can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0380] Understandably, the first single layer 23 has a lower modulus, so it is less likely to affect the bending performance of the second bending part 20d, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0381] In other embodiments, the modulus of the first single layer 23 may also satisfy other ranges. This application does not specifically limit the application.

[0382] For example, the first single layer 23 may be made of T300 carbon fiber or T700 carbon fiber.

[0383] Understandably, T300 or T700 carbon fiber has a lower modulus, and the first single layer 23 has a lower modulus in the second bending portion 20d. This makes it less likely to affect the bending performance of the composite layer 22 in the area of ​​the second bending portion 20d, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0384] In other embodiments, the first single layer 23 may also be made of other materials. This application does not specifically limit the application to these materials.

[0385] Please see Figure 17 and combined Figure 16 As shown, in some embodiments, the angle between the fiber arrangement direction of the second single layer 24 in the region of the second bend 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d is d, and d can satisfy: -90°<d≤-20°, for example, d can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0386] It is understandable that by setting the range of the angle d between the fiber arrangement direction of the second single layer 24 in the region of the second bend 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the second bend 20d. In this way, the second bend 20d can have high rigidity, ensuring its bending performance while also providing sufficient support to support the fourth display area 14 of the display panel 10.

[0387] In other implementations, d can satisfy: 20°≤d<90°, for example, d can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0388] It is understandable that by setting the range of the angle d between the fiber arrangement direction of the second single layer 24 in the region of the second bend 20d and the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d, the second single layer 24 and the composite layer 22 are arranged alternately in the region of the second bend 20d. In this way, the second bend 20d can have high rigidity, ensuring its bending performance while also providing sufficient support to support the fourth display area 14 of the display panel 10.

[0389] In other embodiments, the fiber arrangement direction of the second single layer 24 in the region of the second bend 20d may be approximately perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the second bend 20d.

[0390] Please see Figure 17 and combined Figure 16 As shown, by way of example, the fiber arrangement direction of the second single layer 24 in the region of the third fixing portion 20e may be the same as the fiber arrangement direction of the second single layer 24 in the region of the second bending portion 20d.

[0391] It is understandable that the second single layer 24 in the region of the third fixing part 20e and the composite layer 22 in the region of the third fixing part 20e can be arranged alternately. The third fixing part 20e can have high rigidity, thereby having sufficient support and providing sufficient support performance for the fifth display area 15 of the display panel 10.

[0392] For example, the modulus of the second monolayer 24 can be in the range of 220 GPa to 250 GPa. For instance, the modulus of the second monolayer 24 can be equal to 220 GPa, 228 GPa, 230 GPa, 233 GPa, 240 GPa, or 250 GPa, etc.

[0393] Understandably, the second single layer 24 has a lower modulus, so it is less likely to affect the bending performance of the second bending part 20d, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0394] In other embodiments, the modulus of the second single layer 24 may also satisfy other ranges. This application does not specifically limit the application.

[0395] For example, the second single layer 24 may be made of T300 carbon fiber or T700 carbon fiber.

[0396] Understandably, T300 or T700 carbon fiber has a lower modulus, and the second single layer 24 has a lower modulus in the second bending portion 20d. This makes it less likely to affect the bending performance of the composite layer 22 in the area of ​​the second bending portion 20d, and thus less likely to affect the bending performance of the display module 100, resulting in a better user experience.

[0397] In other embodiments, the second single layer 24 may also be made of other materials. This application does not specifically limit the application to these materials.
