[0003] With the development of technology and the demand of electronic device market, foldable electronic devices are more and more widely used. The traditional foldable electronic device includes a display module, a housing device and a folding mechanism. The display module can be fixed on the housing device, and the folding mechanism can drive the housing device and the display module to fold or unfold relative to each other. The display module generally includes a display panel and a support. The support can support the display panel. In order to ensure the bending performance of the support in the bending area, the material of the support generally uses fiber with low elastic modulus. However, due to the low elastic modulus of the support in the area which is not used for bending (i.e. the non-bending area), when the support is fixed to the display screen, the flatness of the non-bending area of the display module is low, and the light and shadow of the non-bending area of the display module is poor.

[0084] In a possible implementation, an angle between the arrangement direction of the second type of fiber yarn of the first single layer and the arrangement direction of the second type of fiber yarn of the composite layer is within a range of greater than -90° to less than or equal to -20°, or within a range of greater than or equal to 20° to less than 90°, or the arrangement direction of the second type of fiber yarn of the first single layer is perpendicular to the arrangement direction of the second type of fiber yarn of the composite layer.

[0085] It can be understood that by setting the angle between the arrangement direction of the second type of fiber yarn of the first single layer and the arrangement direction of the second type of fiber yarn of the composite layer within the range of greater than -90° to less than or equal to -20°, or within the range of greater than or equal to 20° to less than 90°, or the arrangement direction of the second type of fiber yarn of the first single layer can be substantially perpendicular to the arrangement direction of the second type of fiber yarn of the composite layer, the first single layer and the composite layer are staggered. In this way, the support can have high rigidity and sufficient support performance while ensuring the bending performance of the support. BRIEF DESCRIPTION OF DRAWINGS

[0107] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0108] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connection", and "joint" should be understood in a broad sense, for example, "connection" can be detachable connection or non-detachable connection, can be direct connection or indirect connection through an intermediate medium, and can be electrical connection or mechanical connection. Among them, "fixed connection" refers to the connection of each other and the relative position relationship after the connection does not change. The relative arrangement of component A and component B can be that component A projects to obtain projection C along the target direction, component B projects to obtain projection D along the target direction, and projection C and projection D can at least mostly overlap. In some embodiments, the mostly overlap can be any of the following cases: projection C is completely located in projection D. Or, projection D is completely located in 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.

[0109] The orientation terms mentioned in the embodiments of the present application, such as "inner", "outer", etc., are only the direction of the reference drawings, therefore, the orientation terms used are for better and clearer illustration and understanding of the embodiments of the present application, and are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0110] The terms "first", "second", and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a specific sequential or chronological order. It is to be understood that the use of these terms herein is merely for distinguishing between the objects and does not necessarily indicate a specific order or chronology of coming into being. Unless otherwise defined, all terms used in the description and the claims of the present application, including technical terms, scientific terms, common terms, and scientific-technical terms, have the same meaning as commonly understood by one of ordinary skill in the art to which the present application pertains. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0111] In addition, in the embodiments of the present application, the relative positional relationship mentioned, such as parallel, perpendicular, etc. These limits are for the current process level, not an absolute strict limit, and a small amount of deviation is allowed, and approximately parallel, approximately perpendicular, etc. can be used. For example, A is parallel to B, which means that A and B are parallel or approximately parallel, and the included angle between A and B is between 0 degrees and 10 degrees. For example, A is perpendicular to B, which means that A and B are perpendicular or approximately perpendicular, and the included angle between A and B is between 80 degrees and 100 degrees.

[0112] FIG. 1 is a structural schematic diagram of an embodiment of an electronic device 1000 in a flat state according to the present application. FIG. 2 is a structural schematic diagram of an embodiment of the electronic device 1000 in a folded state according to the present application.

[0113] As shown in FIGS. 1 and 2, the present application provides a foldable electronic device 1000. The electronic device 1000 can be a mobile phone, a tablet computer, a personal computer, a notebook computer, a vehicle-mounted device, or a wearable device, etc. The electronic device 1000 in the embodiments shown in FIGS. 1 and 2 is taken as a mobile phone for illustration. It can be understood that the number of folds of the electronic device 1000 is not limited to one as shown in FIGS. 1 and 2, that is, the electronic device 1000 is not limited to a two-fold electronic device as shown in FIGS. 1 and 2. In other embodiments, the number of folds of the electronic device 1000 can be greater than one, that is, the electronic device 1000 can be a more than two-fold electronic device.

[0114] It can be understood that, hereinafter, for the convenience of description, 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, 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 can be understood that the coordinate system of the electronic device 1000 can also be flexibly set according to specific needs. For example, the positive direction of the X-axis is defined as a first direction, the positive direction of the Z-axis is defined as a second direction, the positive direction of the Y-axis is defined as a third direction, the negative direction of the X-axis is defined as a fourth direction, the negative direction of the Z-axis is defined as a fifth direction, and the negative direction of the Y-axis is defined as a sixth direction. In other embodiments, the first direction, the second direction, the third direction, the fourth direction, the fifth direction, and the sixth direction can also be flexibly set according to needs, as long as the first direction, the second direction, the third direction, the fourth direction, the fifth direction, and the sixth direction are different.

[0115] For example, the direction of the rotation axis of the electronic device 1000 can be the Y-axis direction, and the electronic device 1000 can be relatively unfolded or folded along the Y-axis direction. In this way, when the electronic device 1000 is in a folded state, the size of the electronic device 1000 in the X-axis direction becomes smaller. In other embodiments, the direction of the rotation axis of the electronic device 1000 can also be other directions.

[0116] FIG. 3 is a partially exploded schematic view of the electronic device 1000 shown in FIG. 1 in an embodiment. FIG. 4 is a partially cross-sectional schematic view of the electronic device 1000 shown in FIG. 2 along the A-A line in an embodiment.

[0117] Referring to FIGS. 3 and 4, in combination with FIGS. 1 and 2, the electronic device 1000 can 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 to the housing device 300, and the housing device 300 can be used to drive the display module 100 to be relatively unfolded or folded. It can be understood that FIG. 1 and the relevant drawings hereinafter only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1 and the drawings hereinafter. In addition, the electronic device 1000 can include more or fewer structures, for example, the electronic device 1000 can also include a camera module (not shown).

[0118] 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 can be understood that in the present application, the first folding mechanism 310 can be an inner folding mechanism or an outer folding mechanism. The inner folding mechanism refers to a folding mechanism that can fold at least part of the display module 100 between the two housings. The outer folding mechanism refers to a folding mechanism that can fold at least part of the display module 100 outside the housing device 300. The present application does not specifically limit the first folding mechanism 310. In the present embodiment, the first folding mechanism 310 is described as an inner folding mechanism.

[0119] Referring to FIG. 3, in combination with FIGS. 1 and 2, when the first housing 210, the second housing 220 and the first folding mechanism 310 are unfolded relative to each other to the unfolded state, the electronic device 1000 is in the unfolded state. Exemplarily, when the electronic device 1000 is in the unfolded 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° (allowing slight deviations, such as 165°, 177° or 185°, etc.).

[0120] As shown in FIGS. 2 and 4, when the first housing 210, the second housing 220 and the first folding mechanism 310 are folded relative to each other to the folded state, the electronic device 1000 is in the folded state. Exemplarily, when the electronic device 1000 is in the folded state, the first housing 210 and the second housing 220 can be close to each other, 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 are converted from the unfolded state to the folded state, the first folding mechanism 310 can enclose a containing space 3101. It can be understood that different structures of the first folding mechanism 310 can have different shapes of the containing space 3101.

[0121] As shown in FIGS. 1 and 2, the display module 100 can include a first part 100a, a second part 100b and a third part 100c connected in sequence. The second part 100b is connected between the first part 100a and the third part 100c. Exemplarily, FIG. 1 illustrates an example in which the first part 100a, the second part 100b and the third part 100c are arranged along the X-axis direction. In FIG. 1 and the relevant drawings below, the first part 100a, the second part 100b and the third part 100c are schematically distinguished by dashed lines. In other embodiments, the first part 100a, the second part 100b and the third part 100c can also have other arrangements.

[0122] As shown in FIG. 1 and FIG. 3, the first part 100a of the display module 100 can be fixed on the first housing 210, for example. The third part 100c can be fixed on the second housing 220. The second part 100b can be disposed opposite to the first folding mechanism 310. When the first folding mechanism 310 unfolds or folds the first housing 210 opposite to the second housing 220, the first housing 210 can drive the first part 100a of the display module 100 to unfold or fold, and the second housing 220 can drive the third part 100c of the display module 100 to unfold or fold. At this time, the second part 100b of the display module 100 can be bent around the third direction.

[0123] As shown in FIG. 1 and FIG. 3, when the electronic device 1000 is in the unfolded state, the display module 100 can be in the unfolded state. For example, the first part 100a, the second part 100b and the third part 100c of the display module 100 can be approximately 180° (allowing slight deviations, such as 165°, 177° or 185°, etc.). At this time, the display module 100 has a continuous large-area display area, that is, the display module 100 can realize large-screen display, and the user experience is better.

[0124] For example, when the electronic device 1000 is in the unfolded state, at least part of the first folding mechanism 310 can be used to support the second part 100b of the display module 100. In this way, when the second part 100b of the display module 100 is subjected to pressing force, extrusion force or impact force, etc., the first folding mechanism 310 can be used to improve the pressure resistance and impact resistance of the second part 100b, that is, to ensure that the second part 100b of the display module 100 is not prone to problems such as concave.

[0125] As shown in FIG. 2 and FIG. 4, when the electronic device 1000 is in the folded state, the display module 100 can be in the folded state. For example, the first part 100a and the third part 100c of the display module 100 can be disposed close to each other. At this time, the first part 100a and the third part 100c of the display module 100 can be arranged along the Z-axis direction. In addition, the second part 100b of the display module 100 can be bent around the third direction.

[0126] Exemplarily, when the electronic device 1000 is in the folded state, the first portion 100a, the second portion 100b and the third portion 100c of the display module 100 can all be located between the first housing 210 and the second housing 220, and the second portion 100b can be located in the accommodation space 3101 of the first folding mechanism 310. Wherein, when the electronic device 1000 is in the folded state, since the first portion 100a, the second portion 100b and the third portion 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 portion 100a can face the display surface of the third portion 100c, the second portion 100b can be folded and arranged between the first portion 100a and the third portion 100c, and the second portion 100b can be located in the accommodation space 3101 of the first folding mechanism 310. The first portion 100a, the second portion 100b and the third portion 100c of the display module 100 can be referred to as inner screens of the display module 100. When the first housing 210 and the second housing 220 are folded, the first portion 100a, the second portion 100b and the third portion 100c can be folded into the space formed by the first housing 210, the second housing 220 and the first folding mechanism 310, and the first portion 100a, the second portion 100b and the third portion 100c can thus be referred to as inner screens of the display module 100. Details will be described below in conjunction with relevant drawings.

[0127] The structure of the electronic device 1000 in some embodiments is specifically described above in conjunction with relevant drawings, and the structure of the display module 100 in some embodiments will be specifically described below in conjunction with relevant drawings.

[0129] As shown in FIG. 5, the display module 100 can include the display panel 10, the support 20 and the protection 30. It can be understood that FIG. 5 and relevant drawings below only schematically show some components included in the display module 100, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 5 and each drawing below. In addition, the display module 100 can include more or fewer structures, for example, when the display module 100 includes more structures, the display module 100 can further include structures such as a back film (not shown) and a polarizer (POL) (not shown). In an embodiment, the display module 100 can further include a touchpad (not shown) and the like.

[0130] Exemplarily, the display panel 10 can be used to display images, etc. The display panel 10 can adopt 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 display panel, a micro organic light-emitting diode display panel, or a quantum dot light emitting diode (QLED) display panel, etc.

[0131] As shown in FIG. 5, along the first direction, the display panel 10 can include the first display area 11, the second display area 12, and the third display area 13 connected in sequence. In other words, the second display area 12 is connected between the first display area 11 and the third display area 13. It can be understood that FIG. 5 schematically distinguishes the first display area 11, the second display area 12, and the third display area 13 by dashed lines. In other embodiments, the first display area 11, the second display area 12, and the third display area 13 can also have other arrangement modes.

[0132] As shown in FIG. 5, along the first direction, the support 20 can include the first fixed part 20a, the first bending part 20b, and the second fixed part 20c connected in sequence. The first bending part 20b can be connected between the first fixed part 20a and the second fixed part 20c. The support 20 can be bent around the third direction at the first bending part 20b. It can be understood that FIG. 5 schematically distinguishes the first fixed part 20a, the first bending part 20b, and the second fixed part 20c by dashed lines. In other embodiments, the first fixed part 20a, the first bending part 20b, and the second fixed part 20c can also have other arrangement modes.

[0138] Referring to FIG. 5, and in combination with FIG. 1 and FIG. 3, when the electronic device 1000 is in the unfolded state, the display panel 10, the support 20, and the protection 30 can all be in the unfolded state. The first display area 11, the second display area 12, and the third display area 13 of the display panel 10 can be substantially 180° (allowing for slight deviations, such as 165°, 177°, or 185°, etc.). In addition, the first fixed portion 20a, the first bending portion 20b, and the second fixed portion 20c of the support 20 can form a plate-like structure.

The specific embodiments are not limited herein.

[0154] FIG. 6D is a partial cross-sectional view of an embodiment of the display module 100 shown in FIG. 3 at the line B-B. FIG. 7 is a partial exploded view of an embodiment of the support member 20 shown in FIG. 5.

[0155] As shown in FIG. 6D and FIG. 7, the support member 20 can include a plurality of fiber layers 21 arranged in a stack along the second direction, for example.

[0156] The plurality of fiber layers 21 can include a composite layer 22, a first single layer 23, and a second single layer 24, for example. The first single layer 23 can be located on one side of the composite layer 22, and the second single layer 24 can be located on a side of the composite layer 22 distal from the first single layer 23. It can be understood that the composite layer 22 refers to a fiber layer composed of at least two different fibers. The single layer refers to a fiber layer composed of the same kind of fiber.

[0157] As shown in FIG. 6D, the support member 20 can further include a second adhesive layer 25, for example. The second adhesive layer 25 can be a double-sided PI adhesive tape, in other words, both sides of the second adhesive layer 25 can have an adhesive effect. In other embodiments, the second adhesive layer 25 can also be made of other materials.

[0158] The second adhesive layer 25 can be located on a side of the first single layer 23 distal from the composite layer 22 and fixedly connected with the first single layer 23, for example.

[0159] As shown in FIG. 6A and FIG. 6D, the second adhesive layer 25 can also be fixedly connected with the display panel 10. The support member 20 can be fixedly connected with the display panel 10 through the second adhesive layer 25.

[0160] First embodiment: referring to FIG. 7 and combining FIG. 5, 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 fixed portion 20a can be a second modulus. The modulus of the composite layer 22 in the region of the second fixed portion 20c can be a third modulus. The modulus can be the elastic modulus or the Young's modulus, for example.

[0161] Exemplarily, the second modulus and the third modulus can both be greater than the first modulus.

[0162] It can be understood that by setting the second modulus and the third modulus both greater than the first modulus, the modulus of the composite layer 22 in the area of the first bending portion 20b (see FIG. 5) is lower, which does not easily affect the bending performance of the composite layer 22 in the area of the first bending portion 20b, thereby not easily affecting the bending performance of the display module 100. In addition, the modulus of the composite layer 22 in the area of the first fixed portion 20a (see FIG. 5) and the area of the second fixed portion 20c (see FIG. 5) is higher, the support of the first fixed portion 20a of the support 20 to the first portion 100a (see FIG. 3) of the display module 100 (see FIG. 3) and the support of the second fixed portion 20c to the third portion 100c (see FIG. 3) of the display module 100 are both better, and the flatness of the first portion 100a and the third portion 100c of the display module 100 are both higher, and the light and shadow of the first display area 11 and the third display area 13 (see FIG. 5) of the display panel 10 (see FIG. 5) are both better. In this way, the display module 100 can balance the better bending performance and the higher flatness, and the user's experience and visual experience are both better.

[0163] Exemplarily, the first modulus can be in the range of 220 Gpa (Giga Pascals) to 250 Gpa, for example, the first modulus can be equal to 220 Gpa, 228 Gpa, 230 Gpa, 233 Gpa, 240 Gpa or 250 Gpa, etc.

[0164] It can be understood that by setting the first modulus in the range of 220 Gpa to 250 Gpa, the first modulus is lower, the modulus of the composite layer 22 in the first bending portion 20b is lower, which does not easily affect the bending performance of the composite layer 22 in the area of the first bending portion 20b, thereby not easily affecting the bending performance of the display module 100, and the user's experience is better.

[0165] In other embodiments, the first modulus can also satisfy other ranges. Specifically, the present application does not make any limitation.

[0166] In some embodiments, 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, etc.

[0167] It can be understood 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 at the first fixed portion 20a is higher, the first fixed portion 20a of the support 20 has better support for the first portion 100a of the display module 100, the flatness of the first portion 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.

[0168] In some embodiments, the second modulus can also be in the range of 700Gpa to 1000Gpa, for example, the second modulus can be equal to 700Gpa, 750Gpa, 800Gpa, 888Gpa, 900Gpa or 1000Gpa, etc.

[0169] It can be understood 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 at the first fixed portion 20a is higher, the first fixed portion 20a of the support 20 has better support for the first portion 100a of the display module 100, the flatness of the first portion 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.

[0170] In other embodiments, the second modulus can also satisfy other ranges. Specifically, the present application does not make any limitation.

[0171] In some embodiments, the third modulus can be in the range of 350Gpa to 400Gpa, for example, the third modulus can be equal to 350Gpa, 360Gpa, 370Gpa, 388Gpa, 399Gpa or 400Gpa, etc.

[0172] It can be understood 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 at the second fixed portion 20c is higher, the second fixed portion 20c of the support 20 has better support for the third portion 100c of the display module 100, the flatness of the third portion 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.

[0173] In some embodiments, the third modulus can also be in the range of 700Gpa to 1000Gpa, for example, the third modulus can be equal to 700Gpa, 750Gpa, 800Gpa, 888Gpa, 900Gpa or 1000Gpa, etc.

[0174] It can be understood 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 at the second fixed portion 20c is higher, the second fixed portion 20c of the support 20 has better support for the third portion 100c of the display module 100, the flatness of the third portion 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.

[0175] In other embodiments, the third modulus can also meet other ranges. Specifically, the present application is not limited.

[0176] Exemplarily, the difference between the first modulus and the second modulus can be greater than or equal to 50Gpa, for example, the difference between the first modulus and the second modulus can be equal to 50Gpa, 66Gpa, 70Gpa, 88Gpa or 100Gpa, etc.

[0177] It can be understood that by setting the difference between the first modulus and the second modulus to be greater than or equal to 50Gpa, the modulus of the first bending portion 20b of the support 20 can be ensured to be lower, and the bending performance of the first bending portion 20b of the support 20 is better. It can also ensure that the modulus of the first fixed portion 20a of the support 20 is higher, and the support of the first fixed portion 20a of the support 20 is better. In this way, the display module 100 can balance the better bending performance and the higher flatness, and the user's use experience and visual experience are better.

[0178] In other embodiments, the difference between the first modulus and the second modulus can also meet other ranges. Specifically, the present application is not limited.

[0179] Exemplarily, the difference between the first modulus and the third modulus can be greater than or equal to 50Gpa, for example, the difference between the first modulus and the third modulus can be equal to 50Gpa, 66Gpa, 70Gpa, 88Gpa or 100Gpa, etc.

[0180] It can be understood that by setting the difference between the first modulus and the third modulus to be greater than or equal to 50Gpa, the modulus of the first bending portion 20b of the support 20 can be ensured to be lower, and the bending performance of the first bending portion 20b of the support 20 is better. It can also ensure that the modulus of the second fixed portion 20c of the support 20 is higher, and the support of the second fixed portion 20c of the support 20 is better. In this way, the display module 100 can balance the better bending performance and the higher flatness, and the user's use experience and visual experience are better.

[0181] In other embodiments, the difference between the first modulus and the third modulus can also meet other ranges. Specifically, the present application is not limited.

[0182] Referring to FIG. 7, and in combination with FIG. 5, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixed portion 20a and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b may, for example, be in the range of -10° to 10°, such as -10°, -6°, -2°, 0°, 3°, 8°, or 10°, etc.

[0183] Referring to FIG. 7, and in combination with FIG. 5, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixed portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b may, for example, be in the range of -10° to 10°, such as -10°, -6°, -2°, 0°, 3°, 8°, or 10°, etc.

[0184] In FIG. 7 and the relevant accompanying drawings below, the fiber arrangement direction is schematically shown by a dashed line. A positive value of the included angle represents that the opening of the included angle between the fiber arrangement direction and the third direction (i.e., the positive direction of the Y axis) is simultaneously toward the first direction (i.e., the positive direction of the X axis) and the third direction, and a negative value of the included angle represents that the opening of the included angle between the fiber arrangement direction and the third direction is simultaneously toward the third direction and the fourth direction (i.e., the negative direction of the X axis). It can be understood that the meaning represented by a positive or negative value of the included angle in the following text is the same, and will not be repeated.

[0185] In other embodiments, a positive value of the included angle may, for example, also represent that the opening of the included angle between the fiber arrangement direction and the third direction is simultaneously toward the third direction and the fourth direction. A negative value of the included angle may, for example, also represent that the opening of the included angle between the fiber arrangement direction and the third direction is simultaneously toward the first direction and the third direction. The specific processing may, for example, be flexible according to actual needs, and the present application is not limited.

[0186] It can be understood that, by setting the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixed 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 fixed portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, both in the range of -10° to 10°, the fiber arrangement direction of the composite layer 22 in the region of the first fixed 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 fixed portion 20c can be substantially parallel, and the processing process of the composite layer 22 is simpler, and it is easier to process the fiber layer of different materials in the regions of the first fixed portion 20a, the first bending portion 20b, and the second fixed portion 20c.

[0187] In other embodiments, the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixed 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 fixed portion 20c and the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b can meet other ranges. The specific embodiments are not limited herein.

[0188] Referring to FIG. 7, and in combination with FIG. 5, it is exemplarily defined that the angle between the fiber arrangement direction of the composite layer 22 in the region of the first fixed portion 20a and the third direction is a first angle, and 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.

[0189] Referring to FIG. 7, and in combination with FIG. 5, it is exemplarily defined that the angle between the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b and the third direction is a second angle, and 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.

[0190] Referring to FIG. 7, and in combination with FIG. 5, it is exemplarily defined that the angle between the fiber arrangement direction of the composite layer 22 in the region of the second fixed portion 20c and the third direction is a third angle, and 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.

[0191] It can be understood that, by setting the first angle, the second angle, and the third angle to be within the range of -10° to 10°, the angles between the fiber arrangement direction of the composite layer 22 in the region of the first fixed portion 20a, the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the fiber arrangement direction of the composite layer 22 in the region of the second fixed portion 20c, and the third direction are all small, which can ensure that the modulus of the composite layer 22 in the region of the first bending portion 20b is small, and the bending performance of the composite layer 22 is not easily affected, so that the bending performance of the display module 100 is not easily affected, and the user's use experience is better. In addition, by setting the first angle, the second angle, and the third angle to be within the range of -10° to 10°, the processing technology of the composite layer 22 is simpler, and it is easier to process the fiber layer with different materials in the regions of the first fixed portion 20a, the first bending portion 20b, and the second fixed portion 20c.

[0192] Referring to FIG. 7, and in combination with FIG. 5, it is exemplarily shown that, when the angles between the fiber arrangement direction of the composite layer 22 in the region of the first fixed portion 20a, the fiber arrangement direction of the composite layer 22 in the region of the first bending portion 20b, the fiber arrangement direction of the composite layer 22 in the region of the second fixed 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 fixed 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 fixed portion 20c can be substantially parallel to the third direction.

[0193] In other embodiments, the first angle, the second angle, and the third angle can all satisfy other ranges. The specific embodiments are not limited herein.

[0194] Exemplarily, the composite layer 22 in the region of the first bending portion 20b can use T300 carbon fiber or T700 carbon fiber.

[0195] Exemplarily, T300 carbon fiber refers to a specific grade or type of carbon fiber. Carbon fiber refers to a new type of material with high strength and high modulus in the form of fiber, with a carbon content of more than 90%. T300 carbon fiber can generally include 93.68% carbon elements and 5.964% nitrogen elements. T300 carbon fiber has a core-sheath structure, poor structural uniformity, and weak orientation of graphite microcrystals. When T300 carbon fiber is subjected to external force, it has large deformation, and the modulus of T300 carbon fiber is low. In an embodiment, the modulus of T300 carbon fiber is about 230 Gpa. It can be understood that T is the code of the carbon fiber product series, and 93.68% and 5.964% refer to the mass percentage. The same symbols will not be described again when they appear again in the following text.

[0196] It can be understood that the core-sheath structure generally refers to a special fiber structure form, which means that the fiber is composed of an outer "sheath" and an inner "core". Graphite crystallites are small crystalline structures formed by carbon atoms arranged in a hexagonal grid. The degree of orientation of the graphite crystallites reflects the consistency of the arrangement direction of the graphite crystallites in the material. High degree of orientation means that the graphite crystallites are more orderly arranged in a particular direction.

[0197] Exemplarily, the T700 carbon fiber refers to a specific grade or type of carbon fiber. The T700 carbon fiber can generally include 95.58% carbon elements and 4.24% nitrogen elements. Compared with the T300 carbon fiber, the T700 carbon fiber has a weakened core-sheath structure, improved structural uniformity, improved degree of orientation of graphite crystallites, reduced deformation when subjected to external force, and higher modulus. In an embodiment, the modulus of the T700 carbon fiber is about 240 Gpa.

[0198] It can be understood that the modulus of the T300 carbon fiber or the T700 carbon fiber is low, and the modulus of the composite layer 22 in the first bending portion 20b is low, which does not easily affect the bending performance of the composite layer 22 in the area of the first bending portion 20b, thereby not easily affecting the bending performance of the display module 100, and the user experience is better.

[0199] In other embodiments, the composite layer 22 in the area of the first bending portion 20b can also use other materials. The specific application is not limited.

[0200] Exemplarily, the composite layer 22 in the area of the first fixed portion 20a can use M40 carbon fiber or mesophase pitch-based carbon fiber.

[0201] Exemplarily, the M40 carbon fiber refers to a specific grade or type of carbon fiber. The M40 carbon fiber can generally include 99.12% carbon elements and 0.074% nitrogen elements. Compared with the T700 carbon fiber, the M40 carbon fiber has no obvious core-sheath structure, improved structural uniformity, improved degree of orientation of graphite crystallites, reduced deformation when subjected to external force, and higher modulus. In an embodiment, the modulus of the M40 carbon fiber is about 370 Gpa. It can be understood that M is the code of the carbon fiber product series. The same meaning will not be repeated hereinafter.

[0202] Exemplarily, the mesophase pitch-based carbon fiber refers to a specific grade or type of carbon fiber. The mesophase pitch-based carbon fiber can generally include 92% of carbon elements. Compared with the M40 carbon fiber, the mesophase pitch-based carbon fiber has a large number of curved platelet crystal structures in the cross-sectional distribution, the structural uniformity is improved, the orientation degree of the graphite crystallites is higher, and the graphite crystallites are regularly arranged, the mesophase pitch-based carbon fiber has a smaller deformation when subjected to an external force, and the mesophase pitch-based carbon fiber has a higher modulus. In an embodiment, the modulus of the mesophase pitch-based carbon fiber is approximately 800 Gpa.

[0203] It can be understood that the M40 carbon fiber or the mesophase pitch-based carbon fiber has a higher modulus, the composite layer 22 has a higher modulus at the first fixed portion 20a, the first fixed portion 20a of the support 20 has a higher rigidity, the first fixed portion 20a of the support 20 has a better support for the first portion 100a of the display module 100, the first portion 100a of the display module 100 has a higher flatness, the light and shadow of the first display area 11 of the display panel 10 is better, and the user has a better visual experience.

[0204] In other embodiments, the composite layer 22 in the area of the first fixed portion 20a can also use other materials. The specific embodiments are not limited in the present application.

[0205] Exemplarily, the composite layer 22 in the area of the second fixed portion 20c can use the M40 carbon fiber or the mesophase pitch-based carbon fiber.

[0206] It can be understood that the M40 carbon fiber or the mesophase pitch-based carbon fiber has a higher modulus, the composite layer 22 has a higher modulus at the second fixed portion 20c, the second fixed portion 20c of the support 20 has a higher rigidity, the second fixed portion 20c of the support 20 has a better support for the third portion 100c of the display module 100, the third portion 100c of the display module 100 has a higher flatness, the light and shadow of the third display area 13 of the display panel 10 is better, and the user has a better visual experience.

[0207] In other embodiments, the composite layer 22 in the area of the second fixed portion 20c can also use other materials. The specific embodiments are not limited in the present application.

[0208] In some embodiments, the angle between the fiber arrangement direction of the first single layer 23 in the area of the first bending portion 20b and the fiber arrangement direction of the composite layer 22 in the area of the first bending portion 20b is a, and a can satisfy: -90° < a ≤ -20°, for example, a can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0209] It can be understood that, by setting the value range of the angle a between the fiber arrangement direction of the first single layer 23 in the area of the first bending part 20b and the fiber arrangement direction of the composite layer 22 in the area of the first bending part 20b, the first single layer 23 in the area of the first bending part 20b and the composite layer 22 in the area of the first bending part 20b are staggered arrangement. In this way, the first bending part 20b can have higher rigidity, and can have sufficient support performance in the case of guaranteeing the bending performance of the first bending part 20b, thereby being able to provide sufficient support performance for the second display area 12 of the display panel 10.

[0210] In other embodiments, a can satisfy: 20°≤a<90°, for example, a can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0211] It can be understood that, by setting the value range of the angle a between the fiber arrangement direction of the first single layer 23 in the area of the first bending part 20b and the fiber arrangement direction of the composite layer 22 in the area of the first bending part 20b, the first single layer 23 in the area of the first bending part 20b and the composite layer 22 in the area of the first bending part 20b are staggered arrangement. In this way, the first bending part 20b can have higher rigidity, and can have sufficient support performance in the case of guaranteeing the bending performance of the first bending part 20b, thereby being able to provide sufficient support performance for the second display area 12 of the display panel 10.

[0212] In other embodiments, the fiber arrangement direction of the first single layer 23 in the area of the first bending part 20b can be substantially perpendicular to the fiber arrangement direction of the composite layer 22 in the area of the first bending part 20b.

[0213] Exemplarily, the fiber arrangement direction of the first single layer 23 in the area of the first fixed part 20a, the fiber arrangement direction of the first single layer 23 in the area of the second fixed part 20c and the fiber arrangement direction of the first single layer 23 in the area of the first bending part 20b can all be the same.

[0214] It can be understood that, the first single layer 23 in the area of the first fixed part 20a and the composite layer 22 in the area of the first fixed part 20a can be staggered arrangement, the first fixed part 20a can have higher rigidity, thereby being able to have sufficient support performance, and being able to provide sufficient support performance for the first display area 11 of the display panel 10. The first single layer 23 in the area of the second fixed part 20c and the composite layer 22 in the area of the second fixed part 20c can be staggered arrangement, the second fixed part 20c can have higher rigidity, thereby being able to have sufficient support performance, and being able to provide sufficient support performance for the third display area 13 of the display panel 10.

[0215] Exemplarily, the modulus of the first single layer 23 can be in the range of 220 Gpa to 250 Gpa, for example, the modulus of the first single layer 23 can be equal to 220 Gpa, 228 Gpa, 230 Gpa, 233 Gpa, 240 Gpa or 250 Gpa, etc.

[0216] It can be understood that the modulus of the first single layer 23 is low, the first single layer 23 does not easily affect the bending performance of the first bending part 20b, thereby not easily affecting the bending performance of the display module 100, and the user experience is better.

[0217] In other embodiments, the modulus of the first single layer 23 can also meet other ranges. Specifically, the present application is not limited.

[0218] Exemplarily, the first single layer 23 can adopt T300 carbon fiber or T700 carbon fiber.

[0219] It can be understood that the modulus of the T300 carbon fiber or the T700 carbon fiber is low, the modulus of the first single layer 23 in the first bending part 20b is low, and the first single layer 23 does not easily affect the bending performance of the composite layer 22 in the area of the first bending part 20b, thereby not easily affecting the bending performance of the display module 100, and the user experience is better.

[0220] In other embodiments, the first single layer 23 can also adopt other materials. Specifically, the present application is not limited.

[0221] In some embodiments, the angle between the fiber arrangement direction of the second single layer 24 in the area of the first bending part 20b and the fiber arrangement direction of the composite layer 22 in the area of the first bending part 20b is b, b can satisfy: -90° < b ≤ -20°, for example, b can be equal to -85°, -70°, -60°, -45°, -30° or -20°, etc.

[0222] It can be understood that by setting the value range of the angle b between the fiber arrangement direction of the second single layer 24 in the area of the first bending part 20b and the fiber arrangement direction of the composite layer 22 in the area of the first bending part 20b, the second single layer 24 in the area of the first bending part 20b and the composite layer 22 in the area of the first bending part 20b are staggered. In this way, the first bending part 20b can have high rigidity, and in the case of ensuring the bending performance of the first bending part 20b, it also has sufficient support performance, thereby being able to provide sufficient support performance for the second display area 12 of the display panel 10.

[0223] In other embodiments, b can satisfy: 20° ≤ b < 90°, for example, b can be equal to 20°, 30°, 45°, 60°, 70° or 85°, etc.

[0224] It can be understood 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 part 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, the second single layer 24 in the region of the first bending part 20b and the composite layer 22 in the region of the first bending part 20b are staggered. In this way, the first bending part 20b can have higher rigidity, and can have sufficient support performance while ensuring the bending performance of the first bending part 20b, thereby being able to provide sufficient support performance to the second display area 12 of the display panel 10.

[0225] In other embodiments, the fiber arrangement direction of the second single layer 24 in the region of the first bending part 20b can be substantially perpendicular to the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b.

[0226] Exemplarily, the fiber arrangement direction of the second single layer 24 in the region of the first fixed part 20a, the fiber arrangement direction of the second single layer 24 in the region of the second fixed 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.

[0229] It can be understood that, the modulus of the second single layer 24 is low, the second single layer 24 does not easily affect the bending performance of the first bending part 20b, thereby not easily affecting the bending performance of the display module 100, and the user experience is better.

[0232] It can be understood that the modulus of the T300 carbon fiber or the T700 carbon fiber is low, the modulus of the second single layer 24 at the first bending part 20b is low, and the bending performance of the composite layer 22 in the area of the first bending part 20b is not easily affected, so that the bending performance of the display module 100 is not easily affected, and the user experience is better.

[0233] In other embodiments, the second single layer 24 can also adopt other materials. The specific embodiments of the present application are not limited.

[0234] The structure of the display module 100 in some embodiments is specifically described above in combination with related drawings, and a method for manufacturing the support 20 will be specifically described below in combination with related drawings.

[0235] FIG. 8A is a partial flow diagram of a method for manufacturing the support 20 according to an embodiment of the present application.

[0236] In some embodiments, the present application also provides a method for manufacturing the support 20, which can be used to manufacture the support 20 described above, and can be used to manufacture the support 20 of other structures in other embodiments. The method includes but is not limited to the following steps S110 to S130, and each step of the method for manufacturing the support 20 will be described below in combination with FIGS. 5, 7 and 8A:

[0237] Step S110: spreading the first type of fiber yarn, the second type of fiber yarn and the third type of fiber yarn in sequence along the first direction, which can also be referred to as yarn spreading. The yarn spreading is a process of uniformly spreading the fiber yarn.

[0238] Exemplarily, 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 in sequence according to the area of the first fixed part 20a, the area of the first bending part 20b and the area of the second fixed part 20c of the support 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 within the range of -10° to 10°.

[0239] Exemplarily, the first type of fiber yarn can be a carbon fiber yarn. In an embodiment, the first type of fiber yarn can be a material having a second modulus, for example, the first type of fiber yarn can be an M40 carbon fiber yarn, a mesophase pitch-based carbon fiber yarn, etc. In other embodiments, the first type of fiber yarn can also be other materials.

[0240] Exemplarily, the second type of fiber yarn can be a carbon fiber yarn. In an 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 a T300 carbon fiber yarn, a T700 carbon fiber yarn, or the like. In other embodiments, the second type of fiber yarn can also be other materials.

[0241] Exemplarily, the second type of fiber yarn can be a carbon fiber yarn. In an 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 a T300 carbon fiber yarn, a T700 carbon fiber yarn, or the like. In other embodiments, the second type of fiber yarn can also be other materials.

[0242] In some embodiments, the method of unwinding the yarn can be mechanical unwinding, airflow unwinding, ultrasonic unwinding, or the like.

[0243] Exemplarily, the mechanical unwinding method can stretch and comb the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn through specific mechanical devices, such as unwinding rollers, combing unwinders, or the like, so that the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn are unwound into a wider, thinner, and more uniform state.

[0244] Exemplarily, the airflow unwinding method can blow and unwind the carbon fiber bundle under the action of airflow by generating high-speed airflow. The airflow can be compressed air, nitrogen, or the like, which is sprayed out 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 single fibers in the first type of fiber yarn, the second type of fiber yarn, and the third type of fiber yarn to separate and expand.

[0245] Exemplarily, the ultrasonic unwinding method can use the high-frequency vibration energy of ultrasonic waves to cause the fiber yarn to be subjected to tiny and rapid mechanical vibrations in a specific device. Such vibrations can break the adhesion and entanglement between 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 gradually expand into a wider, thinner, and more uniform state.

[0246] It can be understood that appropriate unwinding methods can be flexibly selected according to actual needs and actual conditions.

[0247] In other embodiments, the method of unwinding the yarn can also be electrostatic unwinding, or the like. The specific embodiments of the present application are not limited.

[0248] Step S120: processing the spread first type fiber yarn, the second type fiber yarn and the third type fiber yarn to form a composite fiber prepreg, which can also be referred to as a prepreg. The prepreg is a process of pressing and impregnating the fiber yarn with a release paper with resin to form a fiber prepreg.

[0249] In some embodiments, a suitable resin can be selected according to the performance requirements of the fiber prepreg, and prepared according to a certain formula. The fiber yarn after the spreading process is pre-impregnated with the resin, so that the fiber yarn can be fully impregnated in the resin. The pre-impregnated fiber yarn is cured so that it can form a fiber prepreg with certain strength and / or certain stiffness.

[0250] Exemplarily, the first type fiber yarn, the second type fiber yarn and the third type fiber yarn are pre-impregnated with the resin, so that the first type fiber yarn, the second type fiber yarn and the third type fiber yarn are fully impregnated in the resin. The pre-impregnated first type fiber yarn, the second type fiber yarn and the third type fiber yarn are cured so that they form a composite fiber prepreg.

[0251] Exemplarily, the resin can be pitch, polyacrylonitrile or the like. In other embodiments, the resin can be other types of materials.

[0252] Step S130: processing the composite fiber prepreg to form the composite layer 22. Exemplarily, the composite fiber prepreg can be processed by hot pressing, cutting and the like to form the composite layer 22.

[0253] In some embodiments, the composite fiber prepreg can be processed by hot pressing, cutting and the like according to the actual product requirements, so that the composite layer 22 as shown in FIG. 7 can be obtained.

In an embodiment, the second type of fiber yarn is spread out evenly along the first direction, and the angle between the arrangement direction of the second type of fiber yarn of the first single layer 23 and the arrangement direction of the second type of fiber yarn of the composite layer 22 can be in the range of greater than -90° to less than or equal to -20°, or in the range of greater than or equal to 20° to less than 90°, or the arrangement direction of the second type of fiber yarn of the first single layer 23 can be substantially perpendicular to the arrangement direction of the second type of fiber yarn of 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. The pre-impregnated second type of fiber yarn is cured to form a second type of fiber prepreg. The second type of fiber prepreg is hot-pressed and cut to form the first single layer 23 shown in FIG. 7. The first single layer 23 is stacked on the composite layer 22. The specific steps can be referred to the method of making the composite layer 22 described above, which will not be repeated here.

[0256] The second single layer 24 is made. In an embodiment, the second type of fiber yarn is spread out evenly along the first direction, and the angle between the arrangement direction of the second type of fiber yarn of the second single layer 24 and the arrangement direction of the second type of fiber yarn of the composite layer 22 can be in the range of greater than -90° to less than or equal to -20°, or in the range of greater than or equal to 20° to less than 90°, or the arrangement direction of the second type of fiber yarn of the second single layer 24 can be substantially perpendicular to the arrangement direction of the second type of fiber yarn of the composite layer 22.

The pre-impregnated second type of fiber yarn is cured to form a second type of fiber prepreg. The second type of fiber prepreg is hot-pressed and cut to form the second single layer 24 shown in FIG. 7. The second single layer 24 is stacked on the side of the composite layer 22 away from the first single layer 23 to form the support 20 shown in FIG. 5. The specific steps can be referred to the method of making the composite layer 22 described above, which will not be repeated here.

[0297] It can be understood that, by setting the value range of the angle b between the fiber arrangement direction of the second single layer 24 in the region of the first bending part 20b and the fiber arrangement direction of the composite layer 22 in the region of the first bending part 20b, the second single layer 24 in the region of the first bending part 20b and the composite layer 22 in the region of the first bending part 20b are staggered arrangement. In this way, the first bending part 20b can have higher rigidity, and can have sufficient support performance while ensuring the bending performance of the first bending part 20b, so as to provide sufficient support performance to the second display area 12 of the display panel 10.

[0298] It can be understood that other related setting modes of the first single layer 23 and other related setting modes of the second single layer 24 can all refer to the first embodiment. Details will not be described again.

[0299] Third embodiment: please refer to FIG. 5 and FIG. 10, FIG. 10 is a partially exploded schematic view of the support 20 shown in FIG. 7 in an embodiment.

[0300] Exemplarily, the setting mode of the composite layer 22 in the region of the first fixed part 20a and the setting mode of the composite layer 22 in the region of the second fixed part 20c can refer to the related solutions of the first embodiment. Details will not be repeated.

[0301] Exemplarily, the region of the first bending part 20b of the composite layer 22 includes a first region 221 and a second region 222 connected in sequence along the first direction.

[0302] Exemplarily, 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.

[0303] It can be understood that by setting the fourth modulus and the fifth modulus to be different, the modulus of the first region 221 and the modulus of the second region 222 can be different, and the region of the first bending part 20b of the composite layer 22 can simultaneously have different performances.

[0304] Exemplarily, the fourth modulus can be less than the fifth modulus.

[0305] It can be understood that the modulus of the first region 221 is low, the modulus of the composite layer 22 in the first region 221 is low, which is not easy to affect the bending performance of the composite layer 22 in the first region 221, thereby not easy to affect the bending performance of the display module 100 (please refer to FIG. 5), and the user's use experience is better. The modulus of the second region 222 is high, the modulus of the composite layer 22 in the second region 222 is high, the support 20 in the second region 222 has good support for the second part 100b (please refer to FIG. 3) of the display module 100, the flatness of the second part 100b of the display module 100 is higher, the light and shadow of the second display area 12 (please refer to FIG. 5) of the display panel 10 is better, and the user's visual experience is better. In this way, the second part 100b of the display module 100 can balance the better bending performance and the better display effect.

[0306] In other embodiments, the fourth modulus can also be greater than the fifth modulus. Details are not limited by the present application.

[0307] Exemplarily, the number of the first region 221 can be at least two. The number of the second region 222 can be at least one. Along the first direction, at least one second region 222 can be arranged between two first regions 221.

[0308] Exemplarily, the first region 221 can adopt T300 carbon fiber or T700 carbon fiber.

[0309] It can be understood that the modulus of the T300 carbon fiber or the T700 carbon fiber is low, the modulus of the composite layer 22 in the first region 221 is low, the bending performance of the composite layer 22 in the first region 221 is not easily affected, the bending performance of the display module 100 is not easily affected, and the user experience is better.

[0310] In other embodiments, the first region 221 can also use other materials. Specifically, the present application is not limited.

[0311] Exemplarily, the second region 222 can use M40 carbon fiber or mesophase pitch-based carbon fiber.

[0312] It can be understood that the modulus of the M40 carbon fiber or the mesophase pitch-based carbon fiber is high, the modulus of the composite layer 22 in the second region 222 is high, the rigidity of the support 20 in the second region 222 is high, the support 20 in the second region 222 supports the second part 100b (see FIG. 3) of the display module 100 better, the flatness of the second part 100b of the display module 100 is higher, the light and shadow of the second display area 12 (see FIG. 5) of the display panel 10 is better, and the user's visual experience is better.

[0313] In other embodiments, the second region 222 can also use other materials. Specifically, the present application is not limited.

[0314] In other embodiments, the region of the composite layer 22 at the first bending part 20b can use a material with high modulus and a material with low modulus to mix and weave, in other words, in any region of the first bending part 20b of the composite layer 22, the fiber with high modulus and the fiber with low modulus can appear at the same time.

[0315] Exemplarily, the composite layer 22 in the region of the first bending part 20b can adopt a material woven by mixing at least two of T300 carbon fiber, M40 carbon fiber, T700 carbon fiber and mesophase pitch-based carbon fiber. In an embodiment, the composite layer 22 in the region of the first bending part 20b can adopt a material woven by mixing T300 carbon fiber and M40 carbon fiber, a material woven by mixing T300 carbon fiber and mesophase pitch-based carbon fiber, a material woven by mixing T700 carbon fiber and M40 carbon fiber, or a material woven by mixing T700 carbon fiber and mesophase pitch-based carbon fiber. The composite layer 22 in the region of the first bending part 20b can also adopt a material woven by mixing T300 carbon fiber, T700 carbon fiber and M40 carbon fiber, a material woven by mixing T300 carbon fiber, T700 carbon fiber and mesophase pitch-based carbon fiber, a material woven by mixing T300 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber, a material woven by mixing T700 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber, or a material woven by mixing T300 carbon fiber, T700 carbon fiber, M40 carbon fiber and mesophase pitch-based carbon fiber.

[0316] It can be understood that the composite layer 22 in any region of the first bending part 20b can simultaneously have a material with a higher modulus and a material with a lower modulus, the region of the first bending part 20b of the composite layer 22 does not easily affect the bending performance of the display module 100 (see FIG. 3), and can also improve the flatness of the second part 100b (see FIG. 3) of the display module 100, the light and shadow of the second part 100b of the display module 100 is better, and the user's use experience and visual experience are better.

[0317] In other embodiments, the composite layer 22 in the region of the first bending part 20b can be woven by mixing other materials. The specific embodiments are not limited herein.

[0318] Exemplarily, the related setting mode of the first single layer 23 and the related setting mode of the second single layer 24 can also refer to the embodiments described above. Here, no further description is given. It can be understood that, compared to the first embodiment, in the present embodiment, the support 20 can provide better support for the first part 100a, the second part 100b and the third part 100c of the display module 100 without affecting the bending performance of the display module 100, the flatness of the first part 100a, the second part 100b and the third part 100c is higher, and the light and shadow of the first display area 11, the second display area 12 and the third display area 13 are better. In this way, the user's use experience and visual experience are better.

[0319] The fourth implementation manner: it can be understood that the electronic device 1000 described above is taken as an example of one-time folding. In other implementation manners, the electronic device 1000 can also be folded twice and more than twice. The same technical content as most of the above is not described herein again.

[0320] FIG. 11 is a structural schematic diagram of the electronic device 1000 in a flat state according to an embodiment of the present application. FIG. 12 is a structural schematic diagram of the electronic device 1000 in a first folding state according to an embodiment of the present application. FIG. 13 is a structural schematic diagram of the electronic device 1000 in a second folding state according to an embodiment of the present application.

[0321] As shown in FIGS. 11 to 13, the present application provides an electronic device 1000 with folding times greater than one. The electronic device 1000 in the embodiment shown in FIGS. 11 to 13 is also taken as an example of a mobile phone. For ease of description, 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, the extension direction of the rotation axis of the electronic device 1000 is defined as the Y-axis direction, and the width direction of the electronic device 1000 is defined as the Y-axis direction. It can be understood that the coordinate system of the electronic device 1000 can also 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 is defined as the second direction, the positive direction of the Y-axis is defined as the third direction, the negative direction of the X-axis is defined as the fourth direction, the negative direction of the Z-axis is defined as the fifth direction, and the negative direction of the Y-axis is defined as the sixth direction. In other implementation manners, the first direction, the second direction, the third direction, the fourth direction, the fifth direction and the sixth direction can also be flexibly set according to needs, as long as the first direction, the second direction, the third direction, the fourth direction, the fifth direction and the sixth direction are different.

[0322] For example, the direction of the rotation axis of the electronic device 1000 can be the Y-axis direction, and the electronic device 1000 can be relatively unfolded or folded along the Y-axis direction. In this way, when the electronic device 1000 is in a folded state, the size of the electronic device 1000 in the X-axis direction becomes smaller. In other implementation manners, the direction of the rotation axis of the electronic device 1000 can also be other directions.

[0323] FIG. 14 is a partial exploded schematic diagram of the electronic device 1000 in an embodiment shown in FIG. 11. FIG. 15 is a partial cross-sectional schematic diagram of the electronic device 1000 at the C-C line in an embodiment shown in FIG. 13.

[0324] Referring to FIGS. 14 and 15, and in combination with FIGS. 11-13, 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, the second housing 220, the third housing 230, the first folding mechanism 310, and the second folding mechanism 320 can constitute a housing apparatus 300 of the electronic device 1000. The display module 100 can be mounted to the housing apparatus 300, and the housing apparatus 300 can be configured to drive the display module 100 to unfold or fold. It can be understood that FIG. 11 and the following related drawings only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of the components are not limited by FIG. 11 and the following drawings. In addition, the electronic device 1000 can include more or fewer structures, for example, the electronic device 1000 can also include a camera module (not shown).

[0325] Exemplarily, the first folding mechanism 310 can connect the first housing 210 and the second housing 220. The first folding mechanism 310 can be configured to drive the first housing 210 and the second housing 220 to unfold or fold. The second folding mechanism 320 can connect the second housing 220 and the third housing 230. The second folding mechanism 320 can be configured to drive the second housing 220 and the third housing 230 to unfold or fold. It can be understood that in the present application, by providing the first folding mechanism 310 and the second folding mechanism 320 in the electronic device 1000, the electronic device 1000 can be folded multiple times. The first folding mechanism 310 can be an inner folding mechanism. The second folding mechanism 320 can be an outer folding mechanism. The inner folding mechanism refers to a folding mechanism that can fold at least part of the display module 100 between two housings. The outer folding mechanism refers to a folding mechanism that can fold at least part of the display module 100 outside the housing.

[0326] In other embodiments, the first folding mechanism 310 can also be an outer folding mechanism. The second folding mechanism 320 can also be an inner folding mechanism. The specific embodiments are not limited in the present application.

[0327] In the present embodiment, the first folding mechanism 310 is an inner folding mechanism, and the second folding mechanism 320 is an outer folding mechanism.

[0328] Referring to FIG. 14, and in combination with FIG. 11, 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 relatively unfolded to the unfolded state, the electronic device 1000 is in the unfolded state. Exemplarily, when the electronic device 1000 is in the unfolded 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° (allowing some deviation, for example, 165°, 177°, or 185°, etc.).

[0329] Referring to FIG. 12, and in combination with FIG. 14, 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 relatively folded to the first folded state, the electronic device 1000 is in the first folded state. Exemplarily, 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° (allowing some deviation, for example, 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 in the Z-axis direction.

[0330] Referring to FIG. 15, and in combination with FIG. 13, 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 relatively folded to the second folded state, the electronic device 1000 is in the second folded state. Exemplarily, when the electronic device 1000 is in the second folded state, the first housing 210 and the second housing 220 can be close to each other, 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 close to each other, and the second housing 220 and the third housing 230 can be stacked in the Z-axis direction, and the second housing 220 can be 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 are converted from the first folded state to the second folded state, the first folding mechanism 310 can enclose the accommodation space 3101. It can be understood that the first folding mechanism 310 with different structures can have different shapes of the accommodation space 3101. The specific structure of the first folding mechanism 310 and the second folding mechanism 320 is not limited in the present application.

[0331] Referring to FIGS. 14 and 15, and in combination with FIGS. 11-13, the display module 100 includes a first portion 100a, a second portion 100b, a third portion 100c, a fourth portion 100d, and a fifth portion 100e connected in sequence. The second portion 100b can be connected between the first portion 100a and the third portion 100c. The third portion 100c can be connected between the second portion 100b and the fourth portion 100d. The fourth portion 100d can be connected between the third portion 100c and the fifth portion 100e. Exemplarily, both FIG. 11 and FIG. 14 show an example in which the first portion 100a, the second portion 100b, the third portion 100c, the fourth portion 100d, and the fifth portion 100e are arranged along the X-axis direction.

[0332] The first portion 100a of the display module 100 can be fixed on the first housing 210. The third portion 100c can be fixed on the second housing 220. The fifth portion 100e can be fixed on the third housing 230. It can be understood that when the first folding mechanism 310 causes the first housing 210 to unfold or fold relative to the second housing 220, the first housing 210 can drive the first portion 100a of the display module 100 to unfold or fold relative to the third portion 100c, and the second housing 220 can drive the third portion 100c of the display module 100 to unfold or fold relative to the first portion 100a. At this time, the second portion 100b of the display module 100 can be bent. When the second folding mechanism 320 causes the second housing 220 to unfold or fold relative to the third housing 230, the second housing 220 can drive the third portion 100c of the display module 100 to unfold or fold relative to the fifth portion 100e, and the third housing 230 can drive the fifth portion 100e of the display module 100 to unfold or fold relative to the third portion 100c. At this time, the fourth portion 100d of the display module 100 can be bent about the third direction.

[0333] As shown in FIGS. 11 and 14, when the electronic device 1000 is in the unfolded state, the display module 100 can be in the unfolded state. Exemplarily, 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 substantially 180° (allowing slight deviations, such as 165°, 177°, or 185°). At this time, the display module 100 can have a continuous large-area display region, i.e., the display module 100 can achieve large-screen display, and the user experience is better.

[0334] Exemplarily, when the electronic device 1000 is in the unfolded state, at least part of the first folding mechanism 310 can be used to support the second portion 100b, and at least part of the second folding mechanism 320 can be used to support the fourth portion 100d. In this way, when the second portion 100b and the fourth portion 100d of the display module 100 are subjected to pressing force, extrusion force or impact force, etc., 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 portion 100b and the fourth portion 100d, i.e., to ensure that the second portion 100b and the fourth portion 100d are not prone to problems such as denting.

[0335] Referring to FIG. 12, and in combination with FIG. 11, when the electronic device 1000 is in the first folded state, the display module 100 can be in the first folded state. Among them, 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 all be located on the outside of the electronic device 1000. At this time, 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 are folded into the outer screen of the electronic device 1000. Exemplarily, the first portion 100a, the second portion 100b and the third portion 100c of the display module 100 can be approximately 180° (allowing slight deviations, such as 165°, 177° or 185°). The third portion 100c and the fifth portion 100e of the display module 100 are arranged close to each other. At this time, the third portion 100c and the fifth portion 100e of the display module 100 can be arranged along the Z-axis direction. In addition, the fourth portion 100d of the display module 100 can be bent around the third direction.

[0336] As shown in FIG. 13 and FIG. 15, when the electronic device 1000 is in the second folded state, the display module 100 can 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 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. In addition, the second portion 100b and the fourth portion 100d of the display module 100 can be bent around the third direction.

[0337] Exemplarily, when the electronic device 1000 is in the second folded state, the first portion 100a, the second portion 100b and the third portion 100c of the display module 100 can all be located between the first housing 210 and the second housing 220, and the second portion 100b can be located in the accommodation space 3101 of the first folding mechanism 310. The fourth portion 100d and the fifth portion 100e of the display module 100 can both be located outside the second folding mechanism 320 and the third housing 230 (i.e., outside the electronic device 1000), and the fifth portion 100e of the display module 100 can be located on the side of the third housing 230 away from the second housing 220. Wherein, when the electronic device 1000 is in the second folded state, since the first portion 100a, the second portion 100b and the third portion 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 portion 100a can face the display surface of the third portion 100c, the second portion 100b can be folded and arranged between the first portion 100a and the third portion 100c, and the second portion 100b can be located in the accommodation space 3101 of the first folding mechanism 310. The first portion 100a, the second portion 100b and the third portion 100c of the display module 100 can be referred to as inner screens of the display module 100. When the first housing 210 and the second housing 220 are folded, the first portion 100a, the second portion 100b and the third portion 100c can be folded into the space formed by the first housing 210, the second housing 220 and the first folding mechanism 310, and the first portion 100a, the second portion 100b and the third portion 100c can thus be referred to as inner screens of the display module 100. When the second housing 220 and the third housing 230 are folded, at least part of the display surface of the fourth portion 100d and the display surface of the fifth portion 100e of the display module 100 can be located outside the second folding mechanism 320 and the third housing 230, i.e., outside the electronic device 1000, and the fourth portion 100d and the fifth portion 100e of the display module 100 can thus be referred to as outer screens of the display module 100. At this time, the second folding mechanism 320 can be used to fold the fourth portion 100d and the fifth portion 100e of the display module 100 into the outer screens of the electronic device 1000.

[0338] FIG. 16 is a partially exploded schematic view of the display module 100 shown in FIG. 14, according to an embodiment.

[0339] As shown in FIG. 16, the display panel 10 of the display module 100 includes 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 connected in sequence along the X-axis direction. 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 can be understood that FIG. 16 schematically distinguishes 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 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 can also have other arrangement modes.

[0340] As shown in FIG. 16, along the fourth direction (i.e., the negative direction of the X-axis), the support 20 includes the first fixed part 20a, the first bending part 20b, the second fixed part 20c, the second bending part 20d, and the third fixed part 20e connected in sequence. In other words, the first bending part 20b can be connected between the first fixed part 20a and the second fixed part 20c. The second bending part 20d can be connected between the second fixed part 20c and the third fixed part 20e, and the support 20 can be bent at the second bending part 20d. It can be understood that although the arrangement directions of the parts of the support 20 are the same as the arrangement directions of the parts of the display panel 10, within the range of process errors or tolerances, the arrangement directions of the parts of the support 20 can be different from the arrangement directions of the parts of the display panel 10, i.e., the two are not strictly parallel. In addition, FIG. 16 schematically distinguishes the first fixed part 20a, the first bending part 20b, the second fixed part 20c, the second bending part 20d, and the third fixed part 20e by dashed lines. In other embodiments, the first fixed part 20a, the first bending part 20b, the second fixed part 20c, the second bending part 20d, and the third fixed part 20e can also have other arrangement modes.

[0341] It can be understood that the structures of the first fixed part 20a, the first bending part 20b, and the second fixed part 20c of the support 20 can be referred to the structures of the first fixed part 20a, the first bending part 20b, and the second fixed part 20c of the support 20 of the electronic device 1000 described above. Here, specific descriptions are not repeated.

[0342] FIG. 17 is a partially exploded schematic view of the support 20 shown in FIG. 16 in an embodiment.

[0343] As shown in FIGS. 16 and 17, for example, along the second direction, the support 20 can include a plurality of layers of fiber layers 21 stacked.

[0344] Exemplarily, the multi-layer fiber layer 21 includes the composite layer 22, the first single layer 23, and the second single layer 24. It can be understood that the related arrangement modes of the composite layer 22 in the region of the first fixed portion 20a, the region of the first bending portion 20b, and the region of the second fixed portion 20c can refer to the related solutions of various embodiments described above. Details will not be repeated.

[0345] Referring to FIG. 17, in combination with FIGS. 14 and 16, exemplarily, 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 fixed portion 20e can be a seventh modulus. The seventh modulus can be greater than the sixth modulus.

[0346] It can be understood that by setting the seventh modulus to be greater than the sixth modulus, the modulus of the composite layer 22 in the region of the second bending portion 20d is low, which does not easily affect the bending performance of the composite layer 22 in the region of the second bending portion 20d, thereby not easily affecting the bending performance of the display module 100. In addition, the modulus of the composite layer 22 in the region of the third fixed portion 20e is high, the third fixed portion 20e of the support 20 has good support for the fifth portion 100e of the display module 100, the flatness of the fifth portion 100e of the display module 100 is high, and the light and shadow of the fifth display area 15 of the display panel 10 is good. In this way, the display module 100 can balance good bending performance and high flatness, and the user's use experience and visual experience are both good.

[0347] Exemplarily, the sixth modulus can be in the range of 220 Gpa to 250 Gpa, for example, the sixth modulus can be equal to 220 Gpa, 228 Gpa, 230 Gpa, 233 Gpa, 240 Gpa, or 250 Gpa, etc.

[0348] It can be understood that by setting the sixth modulus in the range of 220 Gpa to 250 Gpa, the sixth modulus is low, and the modulus of the composite layer 22 in the region of the second bending portion 20d is low, which does not easily affect the bending performance of the composite layer 22 in the region of the second bending portion 20d, thereby not easily affecting the bending performance of the display module 100.

[0349] In other embodiments, the sixth modulus can also satisfy other ranges. Specifically, the present application is not limited.

[0350] In some embodiments, 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, etc.

[0351] It can be understood that by setting the seventh modulus in the range of 350 GPa to 400 GPa, the seventh modulus is higher, the modulus of the composite layer 22 in the area of the third fixing portion 20e is higher, the rigidity of the third fixing portion 20e of the support 20 is higher, the support property of the third fixing portion 20e of the support 20 to the fifth display area 15 of the display panel 10 is better, the flatness of the fifth portion 100e of the display module 100 is higher, the light and shadow of the fifth portion 100e of the display module 100 is better, and the visual experience of the user is better.

[0352] In some embodiments, 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, etc.

[0353] It can be understood that by setting the seventh modulus in the range of 700 GPa to 1000 GPa, the seventh modulus is higher, the modulus of the composite layer 22 in the area of the third fixing portion 20e is higher, the rigidity of the third fixing portion 20e of the support 20 is higher, the support property of the third fixing portion 20e of the support 20 to the fifth display area 15 of the display panel 10 is better, the flatness of the fifth portion 100e of the display module 100 is higher, the light and shadow of the fifth portion 100e of the display module 100 is better, and the visual experience of the user is better.

[0354] In other embodiments, the seventh modulus can also satisfy other ranges. Specifically, the present application is not limited.

[0355] For example, the difference between the seventh modulus and the sixth modulus can be greater than or equal to 50 Gpa, for example, 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.

[0356] It can be understood that by setting the difference between the seventh modulus and the sixth modulus to be greater than or equal to 50 Gpa, the modulus of the second bending portion 20d of the support 20 can be ensured to be lower, and the bending performance of the second bending portion 20d of the support 20 is better. It can also be ensured that the modulus of the third fixing portion 20e of the support 20 is higher, the rigidity of the third fixing portion 20e of the support 20 is higher, and the support property of the third fixing portion 20e of the support 20 is better. In this way, the display module 100 can balance the better bending performance and the higher flatness, and the user's use experience and visual experience are better.

[0357] In other embodiments, the difference between the seventh modulus and the sixth modulus can also satisfy other ranges. Specifically, the present application is not limited.

[0358] Referring to FIG. 17, and in combination with FIG. 16, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 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 part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e can be equal to -10°, -6°, -2°, 0°, 3°, 8° or 10°, etc.

[0359] It can be understood that by setting the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e in the range of -10° to 10°, the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e can be approximately parallel, and the processing process of the composite layer 22 is simpler, and it is easier to process the fiber layer with different materials in the regions of the second bending part 20d and the third fixed part 20e.

[0360] Referring to FIG. 17, and in combination with FIG. 16, for example, the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the third direction is defined as a fourth angle, and 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.

[0362] It can be understood that by setting the fourth angle and the fifth angle in the range of -10° to 10°, the angles between the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d, the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e and the third direction are all small, which does not easily affect the bending performance of the composite layer 22, thereby not easily affecting the bending performance of the display module 100, and the user experience is better. In addition, by setting the fourth angle and the fifth angle in the range of -10° to 10°, the processing process of the composite layer 22 is simpler, and it is easier to process the fiber layer with different materials in the regions of the second bending part 20d and the third fixed part 20e.

[0363] Referring to FIG. 17, and in combination with FIG. 16, when the angle between the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the third direction and the angle between the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e and the third direction are both equal to 0°, the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e can be substantially parallel to the third direction.

[0364] It can be understood that the fiber arrangement direction of the composite layer 22 in the region of the second bending part 20d and the fiber arrangement direction of the composite layer 22 in the region of the third fixed part 20e are substantially parallel to the third direction, which is not easy to affect the bending performance of the composite layer 22 in the region of the second bending part 20d, thereby not easy to affect the bending performance of the display module 100, and the user experience is better.

[0365] In other embodiments, the fourth angle and the fifth angle can both satisfy other ranges. Specifically, the present application is not limited.
