Description

Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular to a connection structure, a flexible display module and an electronic device. Background Art

[0002] Electronic devices with flexible display modules have attracted widespread attention because they can meet the needs of large screens and portability. Among them, the flexible display module includes multiple functional layers and multiple optical adhesive layers. Two adjacent functional layers are connected by an optical adhesive layer. The optical adhesive layer plays the role of bonding the functional layers on the one hand, and on the other hand, it can also act as a neutral layer to absorb the stress generated when the functional layers are folded to avoid delamination. However, in order to achieve the function of continuous folding and unfolding, the optical adhesive layer is usually composed of a flexible material with a low Young's modulus, which makes the optical adhesive layer less resistant to impact and extrusion, which is easy to cause reliability problems and also reduces the flatness of the flexible display module.

[0056] In the related art, the flexible display module includes multiple functional layers and multiple optical adhesive layers, and two adjacent functional layers are connected by an optical adhesive layer. Among them, the functional layer can be a flexible cover plate, a polarizer, a touch film, a flexible screen or a flexible substrate. On the one hand, the optical adhesive layer plays the role of bonding the various functional layers, and on the other hand, it can also act as a neutral layer to absorb the stress generated when the functional layers are folded to avoid stratification. In order to achieve the function of continuous folding and unfolding, the optical adhesive layer is usually composed of a flexible material with a low Young's modulus. However, due to the low Young's modulus and low stiffness of the optical adhesive layer, the optical adhesive layer has weak impact and extrusion resistance, which is prone to reliability problems. It will also reduce the flatness and visual experience of the flexible display module.

[0057] In view of this, the embodiment of the present application provides a connection structure 20, a flexible display module 100 and an electronic device 300. The connection structure 20 is composed of two materials with different Young's modulus. When the flexible display module 100 uses the connection structure 20 to connect the functional layers 10, the impact resistance and extrusion resistance and flatness of the large surface of the flexible display module 100 can be improved, thereby improving the reliability and flatness of the flexible display module 100. In addition, the creases of the flexible display module 100 can be reduced, and the visual experience of the flexible display module 100 can be improved.

[0058] The electronic device 300 may be a mobile phone, tablet computer, e-reader, laptop computer or wearable device having a flexible display module 100. The electronic device 300 uses the flexible display module 100 to achieve the bending and folding of the screen, so that the electronic device 300 has a relatively compact volume while allowing the flexible display module 100 to have a larger display area.

[0059] In the embodiment of the present application, the electronic device 300 is a foldable mobile phone as an example for description. Figure 1 As shown, the foldable mobile phone may include a housing 200 and a flexible display module 100, and the flexible display module 100 is installed in the housing 200. The electronic device 300 also includes electronic components (not shown in the figure) arranged inside the housing, and the electronic components include circuit boards, processors, cameras, sensors, microphones, batteries, etc., but are not limited thereto. Figure 1 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application.

[0060] The connection structure 20 and the flexible display module 100 provided in the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0061] Figure 2 A cross-sectional schematic diagram of a first flexible display module provided in an embodiment of the present application, Figure 3 for Figure 2 Schematic diagram of the three-dimensional structure of the stacked layers, Figure 4 for Figure 2 Schematic diagram of the structure when the stack is not bent. Figure 5 for Figure 2 Schematic diagram of the structure when the stack is bent.

[0062] like Figure 2 As shown, the flexible display module 100 includes a bending area 101, a non-bending area 102 connected to the bending area 101, a laminate 30, a display layer 55, and an optical adhesive 54. The bending area 101 refers to an area in the flexible display module 100 that is deformed due to bending stress, and the non-bending area 102 refers to an area in the flexible display module 100 other than the bending area 101, and the bending area 101 is located between two non-bending areas 102. The optical adhesive 54 is disposed between the laminate 30 and the display layer 55, and the display layer 55 is bonded to the laminate 30 through the optical adhesive 54.

[0063] like Figure 2 As shown, the number of the stacked layers 30 is one. Of course, the number of the stacked layers 30 may be more than one. When the number of the stacked layers 30 is multiple, the multiple stacked layers 30 are arranged along the thickness direction of the flexible display module 100 (eg Figure 2 X direction) are arranged side by side.

[0064] like Figure 3As shown, the laminate 30 includes two functional layers 10 and a connection structure 20. The two functional layers 10 are connected by the connection structure 20 to form a sandwich structure. The connection structure 20 includes a first region 23 and a second region 24 connected to the first region 23. The first region 23 coincides with the bending region 101, and the second region 24 coincides with the non-bending region 102. During the folding and bending process of the flexible display module 100, the first region 23 of the connection structure 20 will fold or bend along with the bending region 101 (see Figure 4 and Figure 5 As shown in FIG. 1 , the second region 24 moves along with the non-bending region 102 .

[0065] Among them, the functional layer 10 can be a flexible cover plate, a polarizer, a touch film, a flexible screen, a flexible substrate, a back film, a bottom support plate, a protective film 51, a display layer 55, etc., but is not limited thereto.

[0066] In some implementations, the types of the two functional layers 10 in the stack 30 may be the same. In other implementations, the types of the two functional layers 10 in the stack 30 may also be different.

[0067] Figure 6 for Figure 2 Schematic cross-section of the first stack.

[0068] like Figure 6 As shown, the connection structure 20 includes a colloid portion 21, an embedding portion 22, a first region 23, and a second region 24. The first region 23 is connected to the second region 24, and the first region 23 overlaps with the bending region 101 (as shown in FIG. Figure 2 ), the second region 24 overlaps with the non-bending region 102 (as shown Figure 2 As shown in FIG. 1 , the portion of the connection structure 20 corresponding to the first region 23 will bend (fold) as the flexible display module 100 bends (folds). The colloid portion 21 is disposed between the two functional layers 10, and the colloid portion 21 is bonded to the two functional layers 10 respectively. The embedded portion 22 is embedded in the inside of the colloid portion 21 and connected to the colloid portion 21, and the embedded portion 22 is disposed in the inside of the second region 24, and the Young's modulus of the embedded portion 22 is greater than or equal to 1 Gpa, and the Young's modulus of the embedded portion 22 is greater than the Young's modulus of the colloid portion 21.

[0069] In the first region 23, the colloid part 21 with low Young's modulus ensures that the laminate 30 is bendable and can act as a neutral layer to absorb the stress generated when the functional layer 10 is folded and avoid delamination. In the second region 24, since the embedded part 22 has a high Young's modulus and high rigidity, it can effectively disperse the stress during the extrusion impact while ensuring that the first region 23 is bendable, thereby improving the impact resistance and extrusion resistance and flatness of the large surface of the flexible display module 100, and further improving the reliability and flatness of the flexible display module 100. Among them, the large surface refers to the area corresponding to the non-bending area in the flexible display module 100.

[0070] The Young's modulus of the colloid part 21 is usually at the kPa level, and the Young's modulus of the embedded part 22 is at the GPa level. Therefore, the Young's modulus of the connecting structure 20 in the second area 24 can be increased from the kPa level to the GPa level, which can improve the impact resistance, extrusion resistance and flatness of the large surface of the flexible display module 100.

[0071] The connection structure 20 is composed of two materials with different moduli, and the Young's modulus of the high modulus material is greater than or equal to 1 GPa. Therefore, when one of the two functional layers 10 is a flexible cover plate or when the laminate 30 constitutes a flexible cover plate, the light and shadow distortion problem caused by the low rigidity of the flexible cover plate can be solved by the connection structure 20. In addition, the reliability problem caused by the low rigidity strength of the flexible cover plate can also be solved.

[0072] In the embodiment of the present application, the colloid part 21 is made of a material with a low Young's modulus, ensuring that the colloid part 21 can act as a neutral layer to absorb the stress generated when the functional layer 10 is folded, and can ensure that the flexible display module 100 can be bent. Among them, the colloid part 21 can be an optically transparent glue part, a liquid optically transparent glue part or a non-Newtonian fluid part. The colloid part 21 is composed of a material with adhesiveness. The raw material of the colloid part 21 can be at least one or more of acrylate, polyurethane, silicone or epoxy resin, etc. It can be cured by at least one of light curing, heat curing, or moisture curing, and can be connected to the embedded part 22 or the functional layer 10 through chemical bonds, hydrogen bonds, van der Waals forces and other interactions.

[0073] In some possible implementations, the prepolymerized liquid of the colloid part 21 can be covered on the embedding part 22 by coating, inkjet printing, etc. and cured in situ.

[0074] See also Figure 6 As shown, the number of the second regions 24 is two, and the two second regions 24 are respectively arranged on opposite sides of the first region 23. At this time, the number of the non-bending regions 102 is also two (eg, Figure 2 As shown), a non-bending area 102 corresponds to a second area 24 (as shown Figure 2). In some implementations, the number of the second region 24 may also be one, in which case both the bending region 101 and the non-bending region 102 are one, and one non-bending region 102 corresponds to one second region 24. In other implementations, the number of the first region 23 and the second region 24 may also be multiple, and the first region 23 and the second region 24 are alternately arranged. In this case, both the bending region 101 and the non-bending region 102 are multiple and alternately arranged, one bending region 101 corresponds to one first region 23, and one non-bending region 102 corresponds to one second region 24.

[0075] In some implementations, the embedded portion 22 may be made of a material with a high Young's modulus, such as a polyethylene terephthalate portion, a polyimide portion, an ultra-thin glass layer, or a glass fiber portion, etc. In other implementations, the embedded portion 22 may also be made of a plurality of materials with different Young's moduli.

[0076] In some implementations, the Young's modulus of the embedded portion 22 may be less than 100 GPa, so that the Young's modulus of the embedded portion 22 is within 1-100 GPa. In this way, existing materials can be used as the embedded portion 22, which helps to reduce the production cost of the connection structure 20.

[0077] See also Figure 6 As shown, along the first direction X, the size of the embedded portion 22 is smaller than that of the colloid portion 21, ensuring that the embedded portion 22 can be embedded in the inside of the colloid portion 21. In other words, the colloid portion 21 may include the embedded portion 22. The first direction X is defined as the thickness direction of the colloid portion 21.

[0078] See also Figure 6 As shown in FIG. 1 , a portion of the embedded portion 22 is disposed in one of the second regions 24 and another portion is disposed in another second region 24, so that the embedded portion 22 is disposed in the second region 24. In other words, Figure 6 As shown, the embedded portion 22 is equivalent to being divided into two parts spaced apart along the second direction Y, each of the two parts is arranged inside a second area 24, and the first direction X is perpendicular to the second direction Y.

[0079] Figure 7 A cross-sectional schematic diagram of the second laminate provided in an embodiment of the present application.

[0080] In some possible implementations, the embedded portion 22 includes at least one embedded layer 221. For example Figure 6 As shown, the number of the embedded layer 221 can be one. Of course, the number of the embedded layer 221 can also be multiple, such as Figure 7 As shown, the number of embedded layers 221 is two, two embedded layers. Figure 7As shown, each embedded layer 221 includes two embedded segments 222 arranged side by side and at intervals along the second direction Y, and each embedded segment 222 is arranged inside the second region 24. Specifically, there are two second regions 24, and the second regions 24 correspond to the embedded segments 222 one by one, and each embedded segment 222 is arranged inside the corresponding second region 24. In this way, the embedded portion 22 is arranged inside each second region 24, which can improve the impact resistance and extrusion resistance and flatness of the large surface of the flexible display module 100.

[0081] In some possible implementations, the Young's modulus of the two embedded segments 222 of the embedded layer 221 is the same, in other words, the two embedded segments 222 of the embedded layer 221 are composed of the same material. In other implementations, the two embedded segments 222 in the embedded layer 221 can also be composed of different materials. In other words, the Young's modulus of the two embedded segments 222 of the embedded layer 221 is different. It should be noted that the materials of the two embedded segments 222 in the embedded layer 221 are the same or different, and the Young's modulus of each embedded segment 222 is greater than or equal to 1GPa. In the embodiment of the present application, the Young's modulus of the two embedded segments 222 in the embedded layer 221 is the same as an example for explanation.

[0082] Figure 8 A cross-sectional schematic diagram of the third type of stacking provided in an embodiment of the present application.

[0083] In some possible implementations, at least one embedding segment 222 in at least one embedding layer 221 is an integral structure. Figure 6 As shown, the number of embedded layers 221 is one, and the two embedded sections 222 in the embedded layer 221 are both integral structures. Figure 8 As shown, both embedded sections 222 in the embedded layer 221 may be configured as a split structure, or one of the two embedded sections 222 may be configured as an integral structure and the other may be configured as a split structure (not shown in the figure). When there are multiple embedded layers 221, at least one embedded section 222 in each embedded layer 221 may be configured as an integral structure, or at least one embedded section 222 in some embedded layers 221 among the multiple embedded layers 221 may be configured as an integral structure.

[0084] See also Figure 8As shown, when the embedded section 222 is a split structure, the embedded section 222 may include a plurality of embedded bodies 223 arranged side by side and at intervals along the second direction Y. The Young's modulus of each embedded body 223 is greater than or equal to 1 GPa. In addition, the Young's modulus of the plurality of embedded bodies 223 in the embedded section 222 may be the same, or different, or some may be the same and the other may be different. In other words, the plurality of embedded bodies 223 in the embedded section 222 may be made of the same material or different materials.

[0085] The specific structure of the embedded section 222 of the integral structure is not limited here. In some implementations, such as Figure 6 As shown, the embedded section 222 can be a plate structure extending along the second direction Y.

[0086] like Figure 6 As shown, the cross section of the embedded section 222 is rectangular. However, the cross section of the embedded section 222 can also be other shapes, such as a trapezoid. The cross section of the embedded section 222 is parallel to the first direction X and parallel to the length direction of the connecting structure 20.

[0087] In some possible implementations, along the second direction Y, the distance between the embedded segment 222 disposed inside the second region 24 and the boundary line K between the first region 23 and the second region 24 (eg Figure 6 Where L) is greater than or equal to zero. For example, Figure 6 As shown, the number of embedded layers 221 is one, each embedded segment 222 in the embedded layer 221 is arranged inside the second region 24, and the distance between each embedded segment 222 and the second region 24 and the boundary line K of the second region 24 (as shown in FIG. Figure 6 In some implementations, the distance between one embedded segment 222 of the embedded layer 221 and the boundary line K between the first region 23 and the second region 24 may be set to be greater than zero, and the distance between another embedded segment 222 of the embedded layer 221 and the boundary line K between the first region 23 and the second region 24 may be set to zero. In other implementations, the distance between each embedded segment 222 in the embedded layer 221 and the boundary line K between the first region 23 and the second region 24 may be set to zero.

[0088] The distance between the embedding section 222 in the second region 24 and the first region 23 and the second region 24 (eg Figure 6 Where L) can be the same or different. For example, Figure 6 As shown, the distances between the two embedded segments 222 in the embedded layer 221 and the boundary line K between the first region 23 and the second region 24 may be the same. In some implementations, the distances between the two embedded segments 222 in the embedded layer 221 and the boundary line K between the first region 23 and the second region 24 may also be different.

[0089] When there are multiple embedded layers 221, the distance between each embedded segment 222 in each embedded layer 221 and the boundary line K between the first region 23 and the second region 24 is greater than or equal to zero. Figure 7 As shown, the number of embedded layers 221 is two, and the distance between each embedded segment 222 in each embedded layer 221 and the boundary line K between the first region 23 and the second region 24 (as shown in FIG. Figure 7 L) are all greater than zero.

[0090] When there are multiple embedded layers 221, the spacing between the embedded segments 222 arranged in the second region 24 in at least two embedded layers 221 and the first region 23 and the second region 24 may be the same or different, or the spacing between the embedded segments 222 arranged in the second region 24 in each embedded layer 221 and the first region 23 and the second region 24 may also be different.

[0091] When there are multiple embedded layers 221, the multiple embedded layers 221 can be made of different materials, or the multiple embedded layers 221 can be made of the same material, or some of the multiple embedded layers 221 can be made of the same material and the other parts can be made of different materials.

[0092] In some possible implementations, at least one embedded layer 221 is symmetrically arranged relative to a center line P of the first region 23, and the center line P of the first region 23 is parallel to the first direction X and passes through the center of the first region 23. Figure 6 As shown, the number of embedded layers 221 is one, and the embedded layers 221 are symmetrically arranged relative to the center line P of the first region 23. When the number of embedded layers 221 is multiple, at least one embedded layer 221 of the multiple embedded layers 221 is symmetrically arranged relative to the center line P of the first region 23, for example Figure 7 As shown, the number of embedded layers 221 is two, and each embedded layer 221 is symmetrically arranged relative to the center line P of the first region 23 .

[0093] In some possible implementations, there are multiple embedded layers 221, and along the first direction X, the sizes of at least two embedded layers 221 (eg Figure 7 For example Figure 7 As shown, the number of embedded layers 221 is two, and the two embedded layers 221 have the same size in the first direction X. The size of the embedded layer 221 refers to the thickness of the embedded layer 221 in the first direction X (e.g. Figure 7 (shown in H).

[0094] In some implementations, along the first direction X, the sizes of the two embedded layers 221 in the first direction X may also be different. In other implementations, when the number of embedded layers 221 exceeds two, along the first direction X, the sizes of all embedded layers 221 may be the same or different, and along the first direction X, the sizes of some of the at least three embedded layers 221 may be the same, and the sizes of another part may be different.

[0095] Fig. 9 A schematic cross-sectional view of the fourth type of laminate provided in an embodiment of the present application.

[0096] Fig. 9 and Figure 6 The difference between the two is that the structure of the embedded portion 22 is different, and a part of the embedded portion 22 is arranged inside the first area 23, and the other part is arranged inside the second area 24. In the first direction X, the maximum size of the embedded portion 22 in the first area 23 (e.g. Fig. 9 H1) is smaller than the maximum dimension of the embedded portion 22 in the second region 24 (as shown in FIG. Fig. 9 H2 in the figure), the maximum size of the embedded portion 22 in the first region 23 (as shown in Fig. 9 H1) and the maximum size of the embedded portion 22 in the second region 24 (as shown in Fig. 9 In this way, while improving the impact resistance and flatness of the large surface of the flexible display module 100, the crease of the flexible display module 100 can also be weakened, thereby improving the reliability and visual experience of the flexible display module 100.

[0097] For the maximum dimension of the embedded portion 22 in the first region 23 (eg Fig. 9 H1) and the maximum size of the embedded portion 22 in the second region 24 (as shown in Fig. 9 The specific value of the difference between the two (shown as H2 in FIG. 1 ) is not limited here. In some implementations, the maximum size of the embedded portion 22 in the first region 23 (shown as Fig. 9 H1) and the maximum size of the embedded portion 22 in the second region 24 (as shown in Fig. 9 The difference between the two (shown as H2 in FIG. 1 ) can be greater than or equal to 10 μm, which can further improve and reduce the crease of the flexible display module 100 .

[0098] It is understandable that by providing the embedded portion 22 in the bending zone 101 , the rigidity of the bending zone 101 can be improved while ensuring bending, thereby weakening the crease of the bending zone 101 and further improving the visual experience of the flexible display module 100 .

[0099] like Fig. 9As shown, the embedded portion 22 includes an embedded layer 221 of an integral structure, a portion of the embedded layer 221 is disposed inside the first region 23, and another portion is disposed inside the second region 24. In this way, the embedded portion 22 is disposed in both the first region 23 and the second region 24, which can reduce the crease of the flexible display module 100 while ensuring the impact resistance, compression resistance and flatness of the large surface of the flexible display module 100.

[0100] like Fig. 9 As shown, the number of embedded layers 221 is one. In some implementations, the number of embedded layers 221 may also be multiple, and the multiple embedded layers 221 are arranged side by side and at intervals along the first direction X, for example Fig.10 As shown, the number of embedded layers 221 is two. Fig.10 A cross-sectional schematic diagram of the fifth type of stack provided in an embodiment of the present application.

[0101] like Fig. 9 As shown, the number of embedded layers 221 is one. At this time, in the first direction X, the maximum size of the embedded layer 221 in the first region 23 (eg Fig. 9 H1 in the figure is the maximum size of the embedded portion 22 in the first region 23, and the maximum size of the embedded layer 221 in the second region 24 (as shown in Fig. 9 H1 in the figure is the maximum dimension of the embedded portion 22 in the second region 24 .

[0102] When there are multiple embedded layers 221, the maximum size of the embedded portion 22 in the first region 23 is the maximum size of all embedded layers 221 in the first region 23, and the maximum size of the embedded portion 22 in the second region 24 is the maximum size of all embedded layers 221 in the second region 24. For example, Fig.10 As shown, the number of embedded layers 221 is two.

[0103] In some possible implementations, such as Fig. 9 As shown, the embedded layer 221 is symmetrically arranged with respect to the center line P of the first region 23. When there are multiple embedded layers 221, each embedded layer 221 can be symmetrically arranged with respect to the center line P of the first region 23 (eg, Fig.10 As shown), or, portions of the plurality of embedded layers 221 may be arranged symmetrically relative to the center line P of the first region 23, or, each embedded layer 221 may be arranged asymmetrically relative to the center line P of the first region 23.

[0104] Fig.11 for Fig. 9 Schematic cross-section of the first embedding layer.

[0105] In some possible implementations, such as Fig.11As shown, the cross section of the embedded layer 221 includes a connecting segment 2212 and two rectangular segments 2211, and the cross section of the embedded layer 221 is parallel to the first direction X and the second direction Y. Each rectangular segment 2211 is arranged inside a second region 24. The connecting segment 2212 is arranged between the two rectangular segments 2211 and connected to the two rectangular segments 2211 respectively, and the first part of the connecting segment 2212 is arranged inside one second region 24, the second part is arranged inside another second region 24, and the third part is arranged inside the first region 23 (as shown in FIG. Fig. 9 Along the first direction X, the surface of one side of the connecting section 2212 is a plane, and the surface of the other side is an arc-shaped concave surface. In other words, an arc-shaped notch is formed on one side of the connecting section 2212.

[0106] like Fig. 9 As shown, along the first direction X, the maximum size of the embedded layer 221 in the first region 23 is the connecting segment 2212 at the boundary line K between the first region 23 and the second region 24 , and the maximum size of the embedded layer 221 in the second region 24 is the size of the rectangular segment 2211 .

[0107] Of course, the shape of the cross section of the connecting section 2212 is not limited to Fig.11 Besides the ones shown, other shapes are possible. Fig.12 A cross-sectional schematic diagram of a second embedded layer provided in an embodiment of the present application. In some implementations, for example Fig.12 As shown, along the first direction X, one side of the connecting section 2212 is a plane, and the other side is formed with a V-shaped notch. Fig.13 A cross-sectional schematic diagram of a sixth laminate provided in an embodiment of the present application, Fig.14 for Fig.13 In other implementations, the cross-section of the connecting section 2212 may also be dumbbell-shaped, such as Fig.14 shown.

[0108] When there are multiple embedded layers 221, the cross-sectional shapes of the multiple embedded layers 221 may be the same. Alternatively, the cross-sectional shapes of the multiple embedded layers 221 may be different, such as Fig.10 Alternatively, the cross-sectional shapes of some of the multiple embedded layers 221 may be the same, and the cross-sectional shapes of other parts may be different.

[0109] Fig.15 A cross-sectional schematic diagram of the seventh stack provided in an embodiment of the present application.

[0110] Fig.15 and Figure 6The difference is that the embedded part 22 includes a plurality of embedded layers 221, and the plurality of embedded layers 221 are arranged side by side and at intervals along the first direction X. Among them, a part of at least one embedded layer 221 is arranged inside the first area 23, and another part is arranged inside the second area 24. At least one embedded layer 221 is an integral structure, and at least one embedded layer 221 includes a plurality of embedded segments 222 arranged side by side and at intervals along the second direction Y. In this way, while improving the impact resistance and extrusion resistance and flatness of the large surface of the flexible display module 100, the crease of the flexible display module 100 can also be weakened, thereby improving the reliability and visual experience of the flexible display module 100. In addition, the thickness of the flexible display module 100 can also be reduced.

[0111] like Fig.15 As shown, the maximum dimension of the embedded portion 22 in the first region 23 is H1, and the maximum dimension of the embedded portion 22 in the second region 24 is H2, H1 is smaller than H2, and the difference between H1 and H2 is greater than or equal to 2 μm, which meets the requirements.

[0112] like Fig.15 As shown, the number of embedded layers 221 is two. In some implementations, the number of embedded layers 221 may be more than two, such as Figure 6 As shown, the number of embedded layers 221 is three. Fig.16 A cross-sectional schematic diagram of the eighth type of stack provided in an embodiment of the present application.

[0113] like Fig.15 As shown, one of the two embedded layers 221 is an integral structure, and the other of the two embedded layers 221 includes a plurality of embedded segments 222. In some implementations, when the number of embedded layers 221 is three or more, the number of embedded layers 221 of the integral structure may also exceed one, and / or the number of embedded layers 221 formed by a plurality of embedded segments 222 may also exceed one.

[0114] like Fig.15 As shown, one of the two embedded layers 221 has a portion disposed inside the first region 23 and another portion disposed inside the second region 24, and the other of the two embedded layers 221 is disposed inside the second region 24. Of course, the number of embedded layers 221 disposed inside both the first region 23 and the second region 24 may be more than one. Fig.16 As shown, the embedded portion 22 includes three embedded layers 221 , wherein a portion of two embedded layers 221 is disposed inside the first region 23 , another portion is disposed inside the second region 24 , and the remaining embedded layer 221 is disposed inside the second region 24 .

[0115] like Fig.15As shown, the cross-section of the embedded layer 221 of the integrated structure is in the shape of a rectangle. Of course, the cross-section of the embedded layer 221 may also be in other shapes, for example, the above-mentioned Figures 11 to 13 The shape of the cross section of any one of the embedding layers 221 .

[0116] like Fig.15 As shown, the embedded layer 221 of the integrated structure is divided into three parts, one of which is disposed inside the first region 23, and the remaining two parts are disposed inside the two second regions 24. In some implementations, the embedded layer 221 of the integrated structure may also be partially disposed inside the first region 23, and the other part disposed inside the second region 24.

[0117] In some possible implementations, the embedding layer 221 formed by a plurality of embedding segments 222 may be disposed inside the second region 24, for example Fig.15 As shown, the embedded layer 221 is composed of two embedded segments 222, and each embedded segment 222 is arranged inside a second region 24. In some other possible implementations, a portion of at least one embedded segment 222 in at least one embedded layer 221 is arranged inside the first region 23, and another portion is arranged inside the second region 24.

[0120] In some possible implementations, such as Fig.15 As shown, the embedding section 222 may be an integral structure. In some other possible implementations, the embedding section 222 may also be a split structure. Specifically, the embedding section 222 may include a plurality of embedding bodies 223 arranged side by side and at intervals along the second direction Y.

[0121] In some possible implementations, at least one embedded layer 221 is symmetrically arranged relative to a center line P of the first region 23, and the center line P of the first region 23 is parallel to the first direction X and passes through the center of the first region 23. Fig.15 As shown, the number of embedded layers 221 is two, and each embedded layer 221 is symmetrically arranged relative to the center of the first region 23. However, the number of embedded layers 221 symmetrically arranged relative to the center of the first region 23 may be more or less than two.

[0122] In some possible implementations, the distance between the embedded segment 222 disposed inside the second region 24 and the boundary line K between the first region 23 and the second region 24 (eg Fig.15 L in the figure) are all greater than or equal to zero. Fig.15 As shown, the distance between each embedded segment 222 and the boundary line K between the first region 23 and the second region 24 is greater than zero. Of course, the distance between one of the two embedded segments 222 and the boundary line K between the first region 23 and the second region 24 can also be set to be greater than zero, and the distance between the other embedded segment and the boundary line K between the first region 23 and the second region 24 can be set to be equal to zero.

In this way, it can also be ensured that a portion of the embedded part 22 is disposed inside the first region 23, and another portion is disposed inside the second region 24, which can improve the impact resistance and extrusion resistance and flatness of the large surface of the flexible display module 100, and at the same time can also reduce the crease of the flexible display module 100.

[0126] like Fig.19 As shown, the number of embedded layers 221 is two. However, the number of embedded layers 221 may be more than two. When the number of embedded layers 221 is more than two, the multiple embedded layers 221 are arranged side by side and at intervals along the first direction X.

[0127] like Fig.19 As shown, a portion of one of the two embedded layers 221 is disposed inside the first region 23, the other portion is disposed inside the second region 24, and the other of the two embedded layers 221 is disposed inside the second region 24. Of course, a portion of each of the two embedded layers 221 may be disposed inside the first region 23, and the other portion may be disposed inside the second region 24.

[0128] like Fig.19 As shown, a portion of each embedded segment 222 of one of the two embedded layers 221 is disposed inside the first region 23, and the other portion is disposed inside the second region 24. However, one of the two embedded segments 222 may be disposed inside the second region 24, a portion of the other may be disposed inside the first region 23, and the other portion may be disposed inside the second region 24, as shown in FIG. Fig. 20 As shown. Among them, Fig. 20 A cross-sectional schematic diagram of a twelfth stack provided in an embodiment of the present application.

[0129] like Fig.19 As shown, the cross-section of each embedding section 222 is rectangular. However, the cross-section of the embedding section 222 may also be other shapes.

[0130] In some possible implementations, there are multiple embedded layers 221, and at least one embedded layer 221 includes two embedded segments 222. For example, Fig.19 As shown, each embedded layer 221 includes two embedded segments 222, wherein each embedded segment 222 of one embedded layer 221 is arranged inside the second region 24, and a portion of each embedded segment 222 of the other embedded layer 221 is arranged inside the first region 23 and another portion is arranged inside the second region 24.

[0134] In some possible implementations, at least one embedding segment 222 in at least one embedding layer 221 is an integral structure. Fig.19 As shown, each embedding segment 222 in each embedding layer 221 is an integral structure. Of course, at least one embedding segment 222 in one embedding layer 221 of the two embedding layers 221 can also be set as an integral structure.

[0135] In some possible implementations, the distance between the embedded segment 222 disposed inside the second region 24 and the boundary line K between the first region 23 and the second region 24 (eg Fig.19 ) can be greater than or equal to zero.
