In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0029] Hereinafter, a display module 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the display module 100 according to the embodiment of the utility model includes a display panel 1, a middle frame 2 and a buffer component 3, the display panel 1 includes a display part 11, a binding part 12 and a bending part 13, the binding part 12 is arranged on the back side of the display part 11, and the two ends of the bending part 13 are respectively connected to the display part 11 and the binding part 12; at least part of the middle frame 2 is arranged around the outer peripheral side of the display panel 1, and the above-mentioned at least part of the middle frame 2 (that is, the part of the middle frame 2 arranged around the outer peripheral side of the display panel 1) is spaced apart from the bending part 13; the buffer component 3 is arranged between the bending part 13 and the middle frame 2, the buffer component 3 includes a first buffer member 31, the first buffer member 31 covers the bending part 13, and the first buffer member 31 abuts against the above-mentioned at least part of the middle frame 2 (for example, the first buffer member 31 abuts against the side plate 22 described later) to separate the bending part 13 from the middle frame 2, and the elastic modulus of the first buffer member 31 is smaller than the elastic modulus of the middle frame 2.

[0031] It can be understood that the first buffer 31 is spaced from the bending portion 13, or the first buffer 31 abuts against the bending portion 13, for example, the first buffer 31 directly abuts against the bending portion 13, or the first buffer 31 indirectly abuts against the bending portion 13 through other components; then the buffer assembly 3 can at least cover the bending portion 13, and the buffer assembly 3 abuts against the above-mentioned at least part of the middle frame 2 (for example, the buffer assembly 3 abuts against the side plate 22 described later) to separate the bending portion 13 from the middle frame 2. It can also be understood that the first buffer 31 can at least cover the portion of the bending portion 13 opposite to the above-mentioned at least part of the middle frame 2, for example, the first buffer 31 at least covers the portion of the bending portion 13 opposite to the side plate 22.

[0032] Therefore, by setting the first buffer 31 to cover the bending portion 13 and abut against at least part of the middle frame 2 to separate the bending portion 13 from the middle frame 2, and the elastic modulus of the first buffer 31 is smaller than the elastic modulus of the middle frame 2, the first buffer 31 has a better ability to buffer and absorb impact, then the part of the first buffer 31 abutting against the middle frame 2 can effectively buffer and absorb the vibration and impact transmitted from the middle frame 2 toward the bending portion 13, so as to reduce the impact transmitted to the bending portion 13 and improve the impact resistance of the display module 100 corresponding to the bending portion 13; at the same time, the buffer component 3 can play a certain supporting role on the bending portion 13, can improve the stability and structural strength of the bending portion 13, so that the bending portion 13 can withstand a larger impact. In addition, the first buffer 31 effectively separates the bending portion 13 from the middle frame 2, can prevent the bending portion 13 from contacting the middle frame 2, and can reduce the damage of the middle frame 2 to the bending portion 13.

[0033] In addition, the first buffer member 31 has a certain flexibility relative to the middle frame 2, so that the middle frame 2 and the bending portion 13 can be flexibly squeezed, which is beneficial to reduce the force on the bending portion 13, so that the buffer component 3 can effectively limit the movement of the bending portion 13, while reducing the damage to the bending portion 13 caused by vibration or impact and collision with its surrounding parts such as the middle frame 2. Therefore, by providing the buffer component 3, the impact resistance and structural strength of the bending portion 13 of the display module 100 can be improved, and the cooperation between the middle frame 2 and the bending portion 13 can be improved.

[0034] In the related art, since the bending portion is relatively fragile, a certain distance is set between the bending portion and the middle frame to keep the two at a certain distance. If the above distance is too large, it is not easy to achieve the narrow frame effect. If the above distance is too small, the bending portion is easy to contact with the middle frame to cause damage to the bending portion. At the same time, the bending portion is fragile and not resistant to impact. In the embodiment of the present application, a buffer component 3 is set to separate the middle frame 2 from the bending portion 13, and the first buffer member 31 can protect the bending portion 13, so that the distance between the bending portion 13 and the middle frame 2 can be appropriately reduced, that is, the avoidance space 10c between the middle frame 2 and the bending portion 13 can be shortened, and the distance between the bending portion 13 and the middle frame 2 in the radial direction of the display module 100 can be reduced, which is conducive to realizing the narrow frame design of the display module 100. The radial direction of the display module 100 refers to the direction passing through the central axis of the display module 100 on the radial plane of the display module 100 . The radial plane of the display module 100 is perpendicular to the central axis of the display module 100 , and the central axis of the display module 100 extends along the thickness direction of the display module 100 .

[0035] It should be noted that the first buffer 31 covers the bending portion 13, which may include the following situations: 1. The first buffer 31 only covers the bending portion 13, but does not cover the display portion 11 and the binding portion 12; 2. The first buffer 31 not only covers the bending portion 13, but also covers a part of the binding portion 12, and / or the first buffer 31 also covers a part of the display portion 11. Among them, the first buffer 31 covers the bending portion 13, which may include the first buffer 31 wrapping the bending portion 13 and abutting against the bending portion 13, or the first buffer 31 wrapping the bending portion 13 and being spaced from the bending portion 13, for example, the first buffer 31 may indirectly abut against the bending portion 13 through other components. For example, in combination with Figure 1 The buffer component 3 is arranged between the bending portion 13 and the middle frame 2, and the buffer component 3 covers the bending portion 13, a part of the binding portion 12 close to the bending portion 13, and a part of the display portion 11 close to the bending portion 13, and the buffer component 3 is in abutment with the bending portion 13, a part of the binding portion 12 close to the bending portion 13, and a part of the display portion 11 close to the bending portion 13. Therefore, the bending portion 13 is tightly fitted with the buffer component 3, and a larger part of the display panel 1 cooperates with the buffer component 3, which can improve the protection ability of the buffer component 3 to the bending portion 13.

[0036] For example, the middle frame 2 includes a side plate 22, which is arranged around the outer periphery of the display panel 1, and the buffer component 3 is arranged between the middle frame 2 and the bending portion 13, and the buffer component 3 is in contact with the side plate 22. Figure 1 The middle frame 2 includes a bottom plate 21 and a side plate 22. The side plate 22 is arranged around the outer peripheral side of the display panel 1. The bottom plate 21 is connected to the side plate 22 and is located on the side of the binding portion 12 away from the display portion 11. A part of the buffer component 3 is arranged between the side plate 22 and the bending portion 13, and another part of the buffer component 3 is arranged between the bottom plate 21 and the binding portion 12, and the buffer component 3 is respectively abutted against the side plate 22 and the bottom plate 21.

[0037] It should be noted that, in the embodiment of the present application, during the assembly process of the display module 100, after the bending portion 13 is bent to connect the display portion 11 and the binding portion 12, the buffer component 3 is installed outside the bending portion 13, that is, the display panel 1 first forms the bending portion 13, and then assembles the bending portion 13 and the buffer component 3. Therefore, during the assembly process of the display module 100, the buffer component 3 can also protect the bending portion 13, improve the collision and extrusion of the bending portion 13, so that the bending portion 13 is not easily damaged, which is conducive to improving the assembly smoothness and yield rate of the display module 100.

[0038] In the above technical solution, a first buffer component 31 is provided to cover the bending portion 13 and abut against at least part of the middle frame 2 to separate the bending portion 13 from the middle frame 2. The elastic modulus of the first buffer component 31 is smaller than the elastic modulus of the middle frame 2. The part where the first buffer component 31 abuts against the middle frame 2 can effectively absorb the vibration transmitted from the middle frame 2 toward the bending portion 13, so as to reduce the impact transmitted to the bending portion 13 and improve the impact resistance of the display module 100 corresponding to the bending portion 13. At the same time, the buffer component 3 can play a certain supporting role on the bending portion 13, and can improve the stability and structural strength of the bending portion 13, so that the bending portion 13 can withstand a larger impact, which is conducive to realizing a narrow frame design.

[0039] In some embodiments of the present application, the middle frame 2 includes a bottom plate 21 and a side plate 22, the bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11, the side plate 22 is arranged around the outer periphery of the display panel 1 and the bottom plate 21, and the buffer component 3 is respectively abutted against the bottom plate 21 and the side plate 22; and / or, the display module 100 also includes a cover plate 4, the cover plate 4 is arranged on the side of the display portion 11 away from the binding portion 12, and the buffer component 3 is abutted against the cover plate 4.

[0040] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0041] In some examples, combined Figure 1 The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11. The side plate 22 is arranged around the outer peripheral side of the display panel 1 and the bottom plate 21. The buffer component 3 is respectively in contact with the bottom plate 21 and the side plate 22. Therefore, by arranging the buffer component 3 to be in contact with the bottom plate 21 and the side plate 22, respectively, the buffer component 3 and the middle frame 2 have a larger contact area, so that the buffer component 3 can better absorb the impact transmitted from the middle frame 2 toward the bending portion 13 in a more all-round manner. At the same time, the buffer component 3 can achieve a larger range of coverage for the bending portion 13. At this time, the buffer component 3 can only cover the bending portion 13 without covering the display portion 11 and the binding portion 12, or the buffer component 3 not only covers the bending portion 13 but also covers the display portion 11 and / or the binding portion 12, which can effectively prevent the collision of the bending portion 13 with the middle frame 2, thereby improving the safety of the bending portion 13.

[0042] In other examples, the middle frame 2 can also be configured to include side panels 22 but not the bottom panel 21. In this case, the display module 100 can include a back panel, which is connected to the side panels 22 and is located on the side of the binding portion 12 away from the display portion 11. The buffer assembly 3 is respectively in contact with the side panels 22 and the back panel.

[0043] In some examples, combined Figure 1 The display module 100 further includes a cover plate 4, which is disposed on a side of the display portion 11 away from the binding portion 12, and the buffer component 3 is in contact with the cover plate 4, for example, the first buffer member 31 is bonded to the cover plate 4. Thus, the middle frame 2 can cooperate with the cover plate 4 to define a space for accommodating the bending portion 13 between the middle frame 2 and the cover plate 4, and the buffer component 3 is also in contact with the cover plate 4, which can improve the stability of the buffer component 3 disposed between the cover plate 4 and the middle frame 2, and the buffer component 3 can also absorb the impact from the cover plate 4 toward the bending portion 13, which can further improve the impact resistance of the bending portion 13.

[0044] For example, combined with Figure 1 The display module 100 includes a cover plate 4, which is disposed on the side of the display portion 11 away from the binding portion 12. The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is disposed on the side of the binding portion 12 away from the display portion 11. The bottom plate 21 and the cover plate 4 can be disposed on both sides of the display panel 1 in the thickness direction thereof, respectively. One end of the side plate 22 away from the bottom plate 21 can be connected to the cover plate 4. An escape space 10c is defined between the cover plate 4, the display panel 1 and the middle frame 2. The buffer component 3 is disposed in the escape space 10c. The buffer component 3 is respectively in contact with the cover plate 4 and the middle frame 2, and the buffer component 3 covers the bent portion 13. Optionally, the cover plate 4 is a light-transmitting member.

[0045] In some embodiments of the present application, Figure 1 and Figure 2 , a groove 2a is formed on the inner surface of the middle frame 2, and the first buffer member 31 fills the groove 2a, for example, a part of the buffer component 3 is matched with the groove 2a. Therefore, by setting the first buffer member 31 to be matched with the groove 2a, the buffer component 3 can utilize part of the space of the middle frame 2, which is conducive to reducing the size of the display module 100, for example, reducing the thickness and / or radial size of the display module 100, which is conducive to achieving a light and thin design and / or miniaturization. Secondly, the first buffer member 31 is matched in the groove 2a, and the middle frame 2 can play a certain limiting role on the buffer component 3, which can improve the stability of the buffer component 3 in the display module 100. Obviously, the setting of the groove 2a can reduce the occupied space of the first buffer member 31 in the display module 100, and the groove 2a can limit the movement of the first buffer member 31, which can improve the stability of the first buffer member 31 in the display module 100.

[0046] For example, Figure 1 and Figure 2 As shown, the middle frame 2 includes a side plate 22 and a bottom plate 21, the inner surface of the bottom plate 21 and the inner surface of the side plate 22 are respectively formed with a groove 2a, and the first buffer 31 includes a first buffer portion 311 and a second buffer portion 312, the first buffer portion 311 fills the groove 2a on the side plate 22, and the second buffer portion 312 fills the groove 2a on the bottom plate 21. Of course, in other examples, at least one of the side plate 22 and the bottom plate 21 is not formed with a groove 2a; or, the middle frame 2 includes the side plate 22 but not the bottom plate 21, and the first buffer 31 can be configured to include the first buffer portion 311 but not the second buffer portion 312.

[0047] In other embodiments of the present application, the inner surface of the middle frame 2 may not be formed with the groove 2a.

[0048] In some embodiments of the present application, Figure 1 and Figure 2 The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11. The side plate 22 is arranged around the outer peripheral side of the display panel 1 and the bottom plate 21. The inner surface of at least one of the bottom plate 21 and the side plate 22 is formed with a groove 2a. Therefore, by setting the inner surface of at least one of the bottom plate 21 and the side plate 22 to form a groove 2a, the buffer component 3 can use part of the space of the middle frame 2, which is conducive to reducing the space occupied by the buffer component 3 in the display module 100 and reducing the volume of the display module 100. For example, the inner surface of the bottom plate 21 is formed with a groove 2a, and part of the buffer component 3 is arranged in the groove 2a, which is conducive to reducing the thickness of the display module 100 and achieving lightness and thinness; and / or, the inner surface of the side plate 22 is formed with a groove 2a, and part of the buffer component 3 is arranged in the groove 2a, which is conducive to reducing the width of the display module 100 and achieving a narrow frame.

[0049] In some embodiments of the present application, Figure 2 , there are multiple grooves 2a on at least one of the bottom plate 21 and the side plate 22, and the multiple grooves 2a are arranged at intervals. Therefore, by setting the grooves 2a on at least one of the bottom plate 21 and the side plate 22 to be multiple and arranged at intervals, so that part of the buffer component 3 is arranged in the corresponding multiple grooves 2a, the stability of the buffer component 3 arranged in the display module 100 can be improved, and the multiple parts of the buffer component 3 arranged in the grooves 2a can improve the impact resistance of the buffer component 3, thereby improving the impact resistance of the bending portion 13 in the display module 100. For example, combined with Figure 2The side plate 22 is formed with a plurality of grooves 2a spaced apart in the thickness direction of the display panel 1, and the bottom plate 21 is formed with a groove 2a. The portion of the buffer component 3 abutting against the side plate 22 is arranged in the plurality of grooves 2a formed in the side plate 22, which can improve the matching stability of the buffer component 3 and the side plate 22, and improve the stability of the buffer component 3 in the display module 100. The portion of the buffer component 3 abutting against the bottom plate 21 is arranged in the groove 2a formed in the bottom plate 21, and the portion of the buffer component 3 can utilize part of the space of the bottom plate 21, which is beneficial to reducing the space occupied by the buffer component 3 in the display module 100, and is beneficial to realizing the thinness of the display module 100.

[0050] In other embodiments of the present application, the number of grooves 2a on at least one of the bottom plate 21 and the side plate 22 may also be one; it can be understood that when the bottom plate 21 and the side plate 22 are respectively formed with grooves 2a, the number of grooves 2a on the bottom plate 21 and the number of grooves 2a on the side plate 22 may be equal or different.

[0051] In some embodiments of the present application, Figure 1 The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11. The side plate 22 is arranged around the outer periphery of the display panel 1 and the bottom plate 21. The first buffer 31 includes a first buffer portion 311 and a second buffer portion 312 connected by bending. The first buffer portion 311 abuts against the side plate 22, and the second buffer portion 312 abuts against the bottom plate 21. Then, the first buffer 31 abuts against the bottom plate 21 and the side plate 22 respectively. Therefore, by setting the first buffer portion 311 to abut against the side plate 22, and the second buffer portion 312 to abut against the bottom plate 21, the first buffer 31 can have a larger contact area to contact the middle frame 2, so that the first buffer 31 can better absorb the impact from the bottom plate 21 and the side plate 22, and the first buffer portion 311 and the second buffer portion 312 can achieve a larger range of coating of the bending portion 13, which is conducive to improving the protection range of the buffer assembly 3.

[0052] In some embodiments of the present application, Figure 1 and Figure 2The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11. The side plate 22 is arranged around the outer periphery of the display panel 1 and the bottom plate 21. The inner surfaces of the bottom plate 21 and the inner surfaces of the side plates 22 are respectively formed with grooves 2a. The first buffer member 31 includes a first buffer portion 311 and a second buffer portion 312 that are bent and connected. The first buffer portion 311 is matched with the groove 2a of the side plate 22 and the first buffer portion 311 is protruded from the inner surface of the side plate 22. The second buffer portion 312 is matched with the groove 2a of the bottom plate 21 and the second buffer portion 312 is flush with the inner surface of the bottom plate 21. Therefore, by setting the first buffer portion 311 to cooperate with the groove 2a of the side panel 22 and protrude from the inner surface of the side panel 22, the groove 2a formed by the side panel 22 can be used to set the first buffer member 31, that is, the display module 100 can accommodate a larger volume of the first buffer portion 311, and part of the first buffer portion 311 does not occupy the space between the inner surface of the side panel 22 and the bending portion 13, which is beneficial to improving the ability of the first buffer portion 311 to absorb impact, and the first buffer portion 311 facilitates the realization of always separating the bending portion 13 from the side panel 22; by setting the second buffer portion 312 to cooperate with the groove 2a of the bottom plate 21 and be flush with the inner surface of the bottom plate 21, the second buffer portion 312 can be set in the groove 2a of the bottom plate 21, that is, the second buffer portion 312 can utilize the occupied space of the bottom plate 21, thereby reducing the setting space of the second buffer portion 312, which is beneficial to realizing the lightweight design of the display module 100.

[0053] In some embodiments of the present application, Figure 1 The first buffer member 31 includes a first buffer portion 311 and a second buffer portion 312 connected by bending, the first buffer portion 311 abuts against at least part of the middle frame 2, and one end of the second buffer portion 312 away from the first buffer portion 311 extends in a direction away from the first buffer portion 311 to exceed the bending portion 13. Thus, the second buffer portion 312 can have a suitable length to separate the bending portion 13 from the bottom plate 21, and the second buffer portion 312 can have a longer length to cooperate with the bottom plate 21 to buffer and absorb the impact from the bottom plate 21, which is conducive to improving the impact resistance of the bending portion 13.

[0054] In some embodiments of the present application, the first buffer member 31 is a foam member or a sponge member. Therefore, the first buffer member 31 can have a good ability to absorb vibration and impact, and the foam member or the sponge member is light in weight and easy to process and shape, which is conducive to reducing the weight increase and processing difficulty of the display module 100.

[0055] In some embodiments of the present application, Figure 1, the first buffer 31 is spaced apart from the bending portion 13, the buffer assembly 3 further includes a second buffer 32, the elastic modulus of the first buffer 31 is smaller than the elastic modulus of the second buffer 32, and the second buffer 32 abuts between the bending portion 13 and the first buffer 31. Therefore, by arranging the second buffer 32 to abut between the bending portion 13 and the first buffer 31, the second buffer 32 can absorb the impact from the first buffer 31 to a certain extent, and can further reduce the impact transmitted to the bending portion 13, so as to improve the impact resistance of the bending portion 13 in the display module 100, and at the same time, the second buffer 32 can support and protect the bending portion 13.

[0056] In the above scheme, the second buffer 32 at least covers the bending portion 13, the first buffer 31 abuts against at least part of the middle frame 2, and the elastic modulus of the first buffer 31 is less than that of the second buffer 32, then the first buffer 31 can absorb the impact from the middle frame 2, and the second buffer 32 further absorbs the impact from the first buffer 31, so as to achieve two-layer absorption of the impact of the middle frame 2 toward the bending portion 13, which can effectively reduce the impact force transmitted to the bending portion 13 and improve the safety of the bending portion 13. Secondly, the second buffer 32 can cooperate with the bending portion 13 to ensure the stability of the setting of the bending portion 13, that is, the second buffer 32 can improve the structural strength of the bending portion 13, which is conducive to the bending portion 13 being able to withstand a larger impact, so that the middle frame 2, the first buffer 31 and the second buffer 32 form a "hard-soft-hard" structure, which can effectively absorb the impact of the buffer assembly 3 and improve the impact resistance of the bending portion 13.

[0057] Optionally, the second buffer member 32 only covers the bending portion 13 but not the binding portion 12 and the display portion 11 , or the second buffer member 32 covers not only the bending portion 13 but also a portion of the binding portion 12 and / or a portion of the display portion 11 .

[0058] In an embodiment of the present application, the elastic modulus of the second buffer member 32 may be smaller than the elastic modulus of the middle frame 2 , or the elastic modulus of the middle frame 2 may be smaller than the elastic modulus of the second buffer member 32 , or the elastic modulus of the middle frame 2 may be equivalent to the elastic modulus of the second buffer member 32 .

[0059] In some embodiments of the present application, the second buffer 32 is UV glue, thermosetting glue, rubber or silicone. Therefore, the second buffer 32 has a certain ability to absorb shock or vibration, and the second buffer 32 can effectively limit the movement of the bending portion 13, support and protect the bending portion 13, so that the second buffer 32 and the bending portion 13 can be formed into a whole, which is conducive to improving the impact resistance of the bending portion 13. Secondly, UV glue, thermosetting glue, rubber or silicone has good processing and molding performance, which is convenient for the processing and molding of the second buffer 32.

[0060] In some embodiments of the present application, the middle frame 2 includes a bottom plate 21 and a side plate 22, the bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11, the side plate 22 is arranged around the outer periphery of the display panel 1 and the bottom plate 21, and the second buffer member 32 abuts against the bottom plate 21, for example, the second buffer member 21 directly abuts against the bottom plate 21, or the second buffer member 21 indirectly abuts against the bottom plate 21 through other components such as the first buffer member 31; and / or, the display module 100 also includes a cover plate 4, the cover plate 4 is arranged on the side of the display portion 11 away from the binding portion 12, and the second buffer member 32 abuts against the cover plate 4.

[0061] In some examples, combined Figure 1 The bottom plate 21 is arranged on the side of the binding portion 12 away from the display portion 11, the side plate 22 is arranged around the outer periphery of the display panel 1 and the bottom plate 21, and the second buffer member 32 is abutted against the bottom plate 21. Therefore, the stability of the second buffer member 32 arranged in the display module 100 can be improved, which is beneficial to improving the supporting effect of the second buffer member 32 on the bending portion 13 and improving its structural strength.

[0062] For example, combined with Figure 1 , the display panel 1 has a side with a bending portion 13 and an escape space 10c between the middle frame 2, the buffer assembly 3 is arranged in the escape space 10c, and the buffer assembly 3 includes a first buffer 31 and a second buffer 32, the first buffer 31 abuts against the side plate 22, the second buffer 32 is arranged between the first buffer 31 and the bending portion 13, and the second buffer 32 abuts against the first buffer 31, the second buffer 32 covers the bending portion 13, and the second buffer 32 abuts against the bottom plate 21. Therefore, the first buffer 31 can absorb most of the impact from the side plate 22, and the second buffer 32 can further protect the bending portion 13, and can effectively reduce the impact transmitted from the side plate 22 to the bending portion 13, and the second buffer 32 can limit the movement of the bending portion 13 to achieve support for the bending portion 13.

[0063] In some examples, combined Figure 1 The display module 100 further includes a cover plate 4, which is disposed on a side of the display portion 11 away from the binding portion 12, and the second buffer 32 abuts against the cover plate 4. Thus, by arranging the second buffer 32 to abut against the cover plate 4, the stability of the second buffer 32 disposed in the display module 100 can also be improved, which is beneficial to improving the supporting effect of the second buffer 32 on the bending portion 13 and improving its structural strength.

[0064] For example, Figure 1 As shown, the middle frame 2 includes a bottom plate 21 and a side plate 22 , the display module 100 also includes a cover plate 4 , the second buffer 32 is indirectly in contact with the bottom plate 21 through the first buffer 31 , and the second buffer 32 is directly in contact with the cover plate 4 .

[0065] In some embodiments of the present application, Figure 1 and Figure 3 The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the binding part 12 away from the display part 11. The side plate 22 is arranged around the outer peripheral side of the display panel 1 and the bottom plate 21. The display module 100 also includes a cover plate 4. The second buffer 32 is respectively connected to the cover plate 4, the bending part 13, and the first buffer 31 by injection molding. The first buffer 31 is formed with a glue injection port 31a connecting the inner and outer sides of the first buffer 31. Therefore, the second buffer 32 can be formed between the first buffer 31 and the bending part 13 by injection molding (for example, low-pressure injection molding process), which can reduce the processing difficulty of the second buffer 32, and the second buffer 32 can be better fitted with the bending part 13 and the first buffer 31 respectively, so that the first buffer 31, the second buffer 32 and the bending part 13 form a whole, which can improve the performance of the buffer component 3 in absorbing impact and protecting the bending part 13, that is, the impact resistance of the bending part 13 can be improved.

[0066] Among them, the second buffer component 32 is injection molded between the bending portion 13 and the first buffer component 31 through the glue injection port 31a of the first buffer component 31, so that the second buffer component 32 can fit tightly to the bending portion 13, the cover plate 4, the first buffer component 31 and part of the structure of the display module 100 (such as the polarizer 5 and the circuit board 7), so that the second buffer component 32 can be more stably arranged in the display module 100, which is beneficial to improving the reliability and stability of the second buffer component 32 covering the bending portion 13.

[0067] Optionally, the first buffer member 31 includes a first buffer portion 311 and a second buffer portion 312 , and at least one of the first buffer portion 311 and the second buffer portion 312 is formed with a glue injection port 31 a to facilitate filling the corresponding glue injection space.

[0068] Optionally, combined Figure 3 The injection molding of the second buffer 32 is realized by using a jig 101, and the jig 101 is formed with a glue injection port 1011. The jig 101 cooperates with the cover plate 4 and the display panel 1 respectively on one side of the bending portion 13 to define a matching cavity 101a. The first buffer 31 is arranged in the matching cavity 101a, and the first buffer 31 abuts against the inner wall of the jig 101, so that the first buffer 31 defines a glue injection cavity 101b between the cover plate 4 and the display panel 1, and a glue injection port 31a connecting the glue injection cavity 101b and the glue injection port 1011 is formed on the first buffer 31, and the second buffer 32 is injection molded in the glue injection cavity 101b. Therefore, the injection molding of the second buffer 32 can be realized more conveniently by the jig 101, and the processing difficulty of the second buffer 32 can be reduced.

[0069] In some embodiments of the present application, Figure 1 and Figure 3 The first buffer member 31 includes a first buffer portion 311 and a second buffer portion 312 which are connected by bending. The first buffer portion 311 abuts against the side plate 22, and the second buffer portion 312 abuts against the bottom plate 21. A glue injection port 31a is formed on the second buffer portion 312. Therefore, the glue injection port 31a is formed on the second buffer portion 312, and the second buffer portion 312 is located on the back side of the display portion 11, so that the display panel 1 can be placed flat, which is convenient for the jig 101 to cooperate with the display panel 1 and the cover plate 4. At this time, the display panel 1 can be placed upright, so that the cover plate 4 is located on the top side and the glue injection port 31a is located on the bottom side. Alternatively, the display panel 1 can also be inverted, so that the cover plate 4 is located on the bottom side and the glue injection port 31a is located on the top side, so that the colloid fills the glue injection cavity 101b, which is convenient for the injection molding of the second buffer member 32.

[0070] For example, combined with Figure 1-Figure 3 The display module 100 includes a cover plate 4, a polarizer 5, a display panel 1, a first back plate 8, a second back plate 9 and a circuit board 7 (e.g., a flexible circuit board). The cover plate 4 is disposed on the upper side of the display panel 1, the polarizer 5 is disposed between the cover plate 4 and the display panel 1, and an optical adhesive 6 is disposed between the polarizer 5 and the cover plate 4. The display panel 1 includes a display portion 11, a binding portion 12 and a bending portion 13. The display portion 11 is opposite to the polarizer 5. The binding portion 12 is located at the lower side of the display portion 11 (i.e., the binding portion 12 is located at the back of the display portion 11). The bending portion 13 connects the display portion 11 and the binding portion 12. The first back plate 8 and the second back plate 9 are both disposed at the lower side of the display portion 11. The first back plate 8 is attached to the display portion 11. An adhesive material 10b is disposed between the second back plate 9 and the first back plate 8 to connect the first back plate 8 and the second back plate 9. The binding portion 12 is electrically connected to the circuit board 7 (e.g., a flexible circuit board), and the binding portion 12 is located between the second back plate 9 and the circuit board 7. The display portion 11 may optionally include a flexible substrate.

[0071] The display module 100 also includes a middle frame 2 and a buffer assembly 3. The middle frame 2 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is arranged on the side of the circuit board 7 away from the display part 11. A tape 10a is arranged between the bottom plate 21 and the circuit board 7 to connect the bottom plate 21 and the circuit board 7. The side plate 22 is arranged around the outer peripheral side of the display panel 1 and the bottom plate 21, and one end of the side plate 22 away from the bottom plate 21 abuts against the edge of the cover plate 4, so that an avoidance space 10c is defined between the polarizer 5, the display panel 1, the circuit board 7 and the middle frame 2, and the bending portion 13 is spaced apart from the middle frame 2. The buffer component 3 is arranged in the avoidance space 10c, and the buffer component 3 includes a first buffer component 31 and a second buffer component 32. The first buffer component 31 includes a first buffer portion 311 and a second buffer portion 312 that are bent and connected. The first buffer portion 311 abuts against the side panel 22, and the second buffer portion 312 abuts against the bottom panel 21. The end of the first buffer portion 311 away from the second buffer portion 312 is connected to the cover plate 4 through the tape 10a. The second buffer component 32 is arranged between the first buffer component 31 and the bent portion 13. The second buffer component 32 abuts against the first buffer component 31 and the cover plate 4 respectively, and the second buffer portion 312 covers the bent portion 13, the portion of the display portion 11 close to the bent portion 13, and the portion of the binding portion 12 close to the bent portion 13.

[0072] Among them, the elastic modulus of the first buffer 31 is smaller than the elastic modulus of the middle frame 2 and the elastic modulus of the second buffer 32. As a result, the first buffer 31 can well absorb the impact and vibration from the middle frame 2, that is, the first buffer 31 can absorb a large part of the vibration and impact, and the second buffer 32 can support and protect the bending portion 13 to prevent the bending portion 13 from being damaged by vibration and impact. Secondly, the second buffer 32 is injection molded between the bending portion 13 and the first buffer 31, so that the second buffer 32 can be closely fitted with the cover plate 4, the polarizer 5, the display part 11, the bending portion 13, the binding part 12 and the circuit board 7, so that the second buffer 32 can be formed as a whole with the side of the cover plate 4, the polarizer 5, the display panel 1 and the circuit board 7 that has the bending portion 13, which can improve the stability of the second buffer 32 and the bending portion 13. Then, the second buffer 32 can effectively limit the movement of the bending portion 13 and improve the structural strength and impact resistance of the bending portion 13.
