[0024] Before introducing the scheme of the present application, it is first pointed out that the drawings of the present application are only schematic and do not represent the actual proportions of the various structures or regions in the product.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application provides a display module 100, which comprises a bending area 10, the display module 100 further comprises a display panel 5, a supporting piece 6 and an elastic body 7, wherein the supporting piece 6 is arranged on the back light surface 51 of the display panel 5, for supporting the display panel 5; the elastic body 7 is arranged on the side of the supporting piece 6 away from the display panel 5, and located in the bending area 10.

[0026] Specifically, the display module 100 of the present application is a flexible display module 100, and the bending area 10 can be bent, facilitating the folding display of the display module 100. Correspondingly, the display panel 5 can also be a flexible display panel, which can be bent along with the bending of the display module 100, and the display panel 5 is used to realize the display function of the display module 100. The support 6 is used to support the display panel 5, and when the display panel 5 is bent, the display panel 5 is supported so that the display surface of the display panel 5 is flat, without affecting the display effect. The elastic body 7 is located on the side of the support 6 away from the display panel 5, and at least in the bending area 10. During the use of the display module 100, if an impact is encountered, the elasticity of the elastic body 7 can avoid the stress generated by the impact from being transmitted to the display panel 5, causing damage to the display panel 5.

[0027] From the above, it can be seen that in the present application, by arranging the elastic body 7 in the bending area 10, the elastic body 7 can play a buffering role when the display module 100 is impacted after falling. Specifically, the impact force generated during the falling of the display module 100 (especially the impact force generated at the bending position of the hinge 4) can be transmitted to the elastic body 7, the elastic body 7 buffers and absorbs the impact force, and then the force transmitted to the display panel 5 is reduced, protecting the display panel 5 and avoiding damage to the display panel 5. In addition, in the unfolded state of the display module 100, the elastic body 7 supports the bending area 10, reducing or even avoiding the generation of creases.

[0028] Among them, in the module process, after the elastic body 7 is formed on the support 6, the support 6 is assembled and bonded with the display panel 5.

[0029] Please continue to refer to Figures 1 to 3 , the display module 100 further comprises a T-shaped block 1, a pressing strip 2, an adhesive 3 and a bending hinge 4; wherein the T-shaped block 1 and the pressing strip 2 are located in the non-display area of the display panel 5, and protect the edges of the display panel 5, wherein the T-shaped block 1 specifically protects the edges of the bending area 10 of the display panel 5, and the pressing strip 2 is located on both sides of the T-shaped block 1. The combination of the pressing strip 2 and the T-shaped block 1 facilitates the flatness of the display surface of the display panel 5. The adhesive 3 is used to bond the hinge 4 to the display panel 5, and the hinge 4 is used to bend and unfold the display panel 5, realizing the bending function of the display module 100.

[0030] Please refer to Figure 2 、 Figure 3 and Figure 4, the bending region 10 includes a bending center region 11 and reverse bending regions 12 located on both sides of the bending center region 11, and the elastic body 7 is located at least in the bending center region 11. Specifically, the bending center region 11 is located in the central region of the bending region 10, and the deformation of the bending center region 11 is the largest after bending. When the bending region 10 is bent to a water drop shape, the bending region 10 below the water drop after bending is the bending center region 11. The display module 100 further includes a non-bending region 13 outside the bending region 10, the display module 100 in the non-bending region 13 does not bend, and the junction of the non-bending region 13 and the bending region 10 is the starting point of the reverse bending region 12, and the reverse bending region 12 extends from the starting point to the bending center region 11, and the reverse bending region 12 and the bending center region 11 are arranged in a spaced manner.

[0031] In an embodiment, as shown in FIG. 1, the elastic body 7 can be located only in the bending center region 11 to provide support for the bending center region 11, which can effectively avoid stress transmission to the display panel 5 after bending, and the elastic body 7 can provide sufficient support for the support 6 of the bending center region 11 to protect the display module 100. In other embodiments, the elastic body 7 can be located not only in the bending center region 11 but also in the reverse bending region 12. Figure 3

[0032] In an embodiment, the elastic body 7 is prepared by a supercritical foaming forming process. Specifically, the material of the elastic body 7 includes at least one of thermoplastic polyurethane elastomer TPU, thermoplastic polyester elastomer TPEE, thermoplastic polyamide elastomer TPAE, polyether block amide PEBA, and ethylene-vinyl acetate copolymer EVA. The supercritical foaming process is used to prepare the elastic body 7, which fully utilizes the fast diffusion rate and large solubility of supercritical carbon dioxide in polymers. During foaming, the polymer is in a semi-solid state, the molten region allows the bubble to grow, and the unmelted region provides the melt strength to maintain the bubble structure. Extremely fast pressure relief induces extremely high nucleation rate to ensure the formation of a bubble structure with micro-nano size and high pore density.

[0033] Specifically, the supercritical foaming is a process in which supercritical carbon dioxide or other gases such as nitrogen are first injected into a special plasticizing device to make the gas and the molten raw material fully and uniformly mixed / diffused to form a single-phase mixed sol, and then the sol is introduced into a mold cavity or an extrusion die to make the sol produce a large pressure drop, so that the gas is precipitated to form a large number of bubble nuclei; in the subsequent cooling forming process, the bubble nuclei in the sol continue to grow and form, and finally a microcellular foamed plastic product is obtained. The pore size can be controlled to be 0.1-10 μm, and the pore density is generally 109-1015 / cm 3 .

[0034] ​Supercritical foaming of microcellular plastics better solves the problem of locking gas. Not only has some unique properties of general foaming materials, but also has excellent mechanical properties compared with traditional foaming materials. The existence of pores reduces the amount of material under the same volume, reduces the weight of plastic parts and saves materials, and shows high performance such as 5 times impact strength and fatigue resistance. The density is reduced by 5%-90%.

[0035] In an embodiment, the material of the support 6 includes at least one of special steel, nickel, titanium, nickel alloy, and titanium alloy. The above-mentioned materials have good rigidity and can effectively support the display panel 5. In an embodiment, the special steel includes stainless steel. The stainless steel has the advantages of easy to obtain and easy to prepare.

[0036] Please continue to refer to Figure 3 and Figure 4 In the first embodiment of the present application, the surface of the support 6 away from the display panel 5 is provided with a first recessed area 60 located in the bending center area 11, and the elastic body 7 is arranged at least in the first recessed area 60.

[0037] Specifically, the first recessed area 60 is located on the surface of the support 6 away from the display panel 5 and in the bending center area 11, which can reduce the thickness of the support 6 and facilitate the bending of the display module 100. In an embodiment, the elastic body 7 is prepared in the first recessed area 60, as shown in Figure 3 The elastic body 7 protrudes from the surface of the support 6 away from the display panel 5, or the surface of the elastic body 7 away from the display panel 5 and the surface of the support 6 away from the display panel 5 are in the same horizontal plane, which is convenient for buffering when impacted. Of course, the elastic body 7 can also be located at other positions on the surface of the support 6 away from the display panel 5.

[0038] In the first embodiment, the thickness of the support 6 provided with the first recessed area 60 is less than or equal to 30 microns, that is, after the first recessed area 60 is formed by slotting on the support 6, the remaining thickness of the support 6 is less than or equal to 30 microns. Specifically, the thickness of the support 6 located in the bending center area 11 can be 30, 25, 20, 15, 10, 5, 3, 1 or 0 microns. By thinning the thickness of the support 6 located in the bending center area 11, the bending of the display module 100 can be facilitated.

[0039] Please refer to Figure 5 and Figure 6 In an application scenario of the first embodiment, the surface of the support 6 away from the display panel 5 is further provided with a second recessed area 61 located in the reverse bending area 12, and the elastic body 7 is further arranged in the second recessed area 61.

[0040] Specifically, the second recessed area 61 is located in the reverse folding area 12 and on the surface of the support 6 facing away from the display panel 5. In an embodiment, the elastic body 7 is arranged in the second recessed area 61, so that the elastic body 7 has better support and buffering effect on the reverse folding area 12, and the state of the reverse folding area 12 in the folded state is stable. In an embodiment, please refer to Figure 6 , the elastic body 7 further extends to the outside of the first recessed area 60 and the second recessed area 61. Specifically, the elastic body 7 not only covers the first recessed area 60 and the second recessed area 61 in the support 6, but also extends to other areas, so as to achieve better support effect on the support 6.

[0041] Among them, the first recessed area 60 and the second recessed area 61 can include an integral recessed area, or can include several recessed areas.

[0042] In an embodiment, please refer to Figure 6 , the elastic body 7 located in the first recessed area 60 and the second recessed area 61 is a convex surface protruding towards the display panel 5. This setting can make the elastic body 7 thickest at the center of the first recessed area 60 and the second recessed area 61, so as to better eliminate the creases at the bending part of the display panel 5.

[0043] In an embodiment, please refer to Figure 6 , the surface of the elastic body 7 facing away from the display panel 5 is a plane. Specifically, the elastic body 7 is prepared on the surface of the support 6 facing away from the display panel 5, and the surface of the elastic body 7 facing away from the display panel 5 is a plane after preparation, which is convenient for preparation.

[0044] In an embodiment, please refer to Figure 6 , the orthographic projection of the elastic body 7 on the display panel 5 covers the display panel 5, that is, the orthographic projection of the elastic body 7 on the plane where the support 6 is located covers the orthographic projection of the display panel 5 on the plane where the support 6 is located. Specifically, the elastic body 7 is prepared on the surface of the support 6 facing away from the display panel 5, which has the advantage of being convenient for preparation. In an embodiment, the surface of the elastic body 7 facing away from the display panel 5 can also be uneven, and the elastic body 7 protrudes in part of the bending center area 11 and the reverse folding area 12, which can enhance the support of the elastic body 7 on the bending center area 11 and the reverse folding area 12.

[0045] In an embodiment, the thickness of the support 6 located in the reverse folding area 12 is less than or equal to 30 microns. Specifically, the thickness of the support 6 located in the reverse folding area 12 can be 30, 25, 20, 15, 10, 5, 3, 1 or 0 microns. By thinning the thickness of the support 6 located in the reverse folding area 12, the bending of the display module 100 can be facilitated.

[0046] Please continue to refer to Figure 3 In the second application scenario of the first embodiment, the thickness of the elastic body 7 arranged in the first recessed area 60 is greater than the depth of the first recessed area 60 in the direction perpendicular to the plane where the display panel 5 is located. Specifically, the elastic body 7 in the first recessed area 60 protrudes out of the first recessed area 60, that is, the elastic body 7 protrudes out of the surface of the support 6 away from the display panel 5, so that the elastic body 7 can provide better support for the bending center area 11 and protect the display module 100. When the display panel 5 is bent, the bending center area 11 of the display panel 5 will be concave. At this time, the elastic body 7 of the protruding support 6 in the direction perpendicular to the display panel 5 can horizontally support the display panel 5, thereby reducing the crease depth of the display panel 5.

[0047] Please continue to refer to Figure 3 In the direction perpendicular to the plane where the display panel 5 is located, the difference D1 between the maximum thickness of the elastic body 7 and the depth of the first recessed area 60 is less than 50 microns. Specifically, the difference D1 between the maximum thickness of the elastic body 7 and the depth of the first recessed area 60 can be 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 microns. The thickness of the elastic body 7 that exceeds the surface of the support 6 away from the display panel 5 can be used as a crease support after the bending center area 11 is concave, thereby improving the display effect of the display module 100 and avoiding the influence of the crease on the display effect and user experience.

[0048] In an embodiment, the difference between the maximum thickness of the elastic body 7 in the first recessed area 60 and the depth of the first recessed area 60 is less than 50 microns in the direction perpendicular to the plane where the display panel 5 is located.

[0049] Please continue to refer to Figure 3 In an embodiment, the surface of the elastic body 7 away from the display panel 5 is a convex surface protruding away from the display panel 5. At this time, the thickness of the elastic body 7 in the central area of the bending center area 11 is the greatest, and the thickness gradually decreases towards both sides, thereby effectively supporting the central area of the bending center area 11.

[0050] Please continue to refer to Figure 3 In an embodiment, the surface of the elastic body 7 close to the display panel 5 is a convex surface protruding towards the display panel 5. This arrangement can further make the thickness of the elastic body 7 in the bending center area 11 decrease from the center to the edge position, thereby further effectively supporting the central area of the bending center area 11. Please continue to refer to Figure 3In an embodiment, the surface of the support 6 away from the display panel 5 is further provided with a plurality of second grooves 62 located in the reverse folding area 12, and the orthographic projection of the elastic body 7 on the display panel 5 is arranged to be spaced from the orthographic projection of the plurality of second grooves 62 on the display panel 5. Specifically, by arranging the plurality of second grooves 62 in the reverse folding area 12, the bending stress of the support 6 in the reverse folding area 12 can be reduced in the bent state, and the service life of the support 6 is improved. At the same time, the elastic body 7 does not cover the second grooves 62, and the elastic body 7 and the second grooves 62 are used in combination to improve the bending performance of the display module 100.

[0051] Please refer to Figure 7 , Figure 8 and Figure 9 In the second embodiment of the present application, the surface of the support 6 away from the display panel 5 is a plane, and the elastic body 7 is arranged in a stack with the support 6. Specifically, the surface of the support 6 away from the display panel 5 is designed as a plane, which facilitates the manufacturing of the elastic body 7 on the surface of the support 6 away from the display panel 5. The elastic body 7 and the support 6 are arranged in a stack, which facilitates the support of the support 6 in the bent state by the elastic body 7, thereby prolonging the service life of the support 6.

[0052] Please refer to Figure 7 and Figure 8 The orthographic projection of the elastic body 7 on the plane of the display panel 5 covers the orthographic projection of the support 6 on the plane of the display panel 5. Specifically, the elastic body 7 covers the surface of the support 6 away from the display panel 5, so as to effectively protect the support 6 in the bent state, enhance the buffering performance of the display module 100, and reduce or even avoid stress impact.

[0053] Please continue to refer to Figure 7 In the first application scenario in the second embodiment, the surface of the support 6 away from the display panel 5 is continuous and uninterrupted. Specifically, the continuous arrangement of the surface of the support 6 can ensure the support strength.

[0054] In an embodiment, please refer to Figure 7The thickness of the support 6 is less than 30 microns. Specifically, the thickness of the support 6 can be 5, 10, 15, 20, 25, or 30 microns. The support 6 with a thickness less than 30 microns in the prior art cannot be directly used in the folding display module 100, because the support performance is limited, although the folding performance can be met, but the display panel 5 will have uneven phenomena such as concave and orange peel. Therefore, the support 6 with a thickness less than 30 microns in the prior art cannot be used. In the present application, the support 6 and the elastic body 7 are stacked and used in combination, so that the elastic body 7 can support the support 6 in the bent state and the unfolded state, meet the use needs of the folding display module 100, use the support 6 with small thickness to reduce the volume of the display module 100, and the elastic body 7 can guarantee the support force of the display module 100, and has a buffering function.

[0055] Referring to Figure 8 In the second application scenario of the second embodiment, the support 6 is provided with a plurality of first through holes 63 located in the bending center area 11 and a plurality of second through holes 64 located in the reverse folding area 12. Specifically, by opening a plurality of first through holes 63 in the bending center area 11 and a plurality of second through holes 64 in the reverse folding area 12, the folding needs are met, and in the folded state, the arrangement of the first through holes 63 and the second through holes 64 is beneficial to reduce the stress of the bending center area 11 and the reverse folding area 12, and ensure the stability of the folding mode.

[0056] Among them, Figure 8 In the embodiment, the elastic body 7 can be further filled into the first through holes 63 and the second through holes 64, and better play a buffering role.

[0057] Referring to Figure 9In the third application scenario of the second embodiment, the support 6 is provided with a plurality of first through holes 63 located in the bending center area 11 and a plurality of second grooves 62 located in the reverse folding area 12, wherein the orthographic projection of the elastic body 7 on the plane of the display panel 5 covers the orthographic projection of the first through holes 63 on the plane of the display panel 5, and the orthographic projection of the elastic body 7 on the plane of the display panel 5 is spaced apart from the orthographic projection of the second grooves 62 on the plane of the display panel 5. The foaming material itself can also block light, and at the same time serve as a support for drop buffering and crease depression. Specifically, by opening the first through holes 63 in the bending center area 11 and the second grooves 62 in the reverse folding area 12, the folding needs are met, and in the folded state, the arrangement of the first through holes 63 and the second grooves 62 is conducive to reducing the stress of the bending center area 11 and the reverse folding area 12, and ensuring the stability of the folding mode. At the same time, the orthographic projection of the elastic body 7 on the display panel 5 covers the bending center area 11, and the orthographic projection of the elastic body 7 on the display panel 5 is spaced apart from the orthographic projection of the second grooves 62 on the display panel 5, so that the elastic body 7 does not cover the reverse folding area 12. The design of the first through holes 63 allows light to pass through, and the light entering from the bending hinge 4 will affect the normal display of the display panel 5, while the elastic body 7 has a light-blocking function, and when the elastic body 7 covers the bending center area 11, it can avoid the light entering from the bending hinge 4 into the inside of the display module 100 to affect the display effect.

[0058] wherein in Figure 9 In an embodiment, the elastic body 7 can be further filled into the plurality of first through holes 63 and the plurality of second grooves 62 to better play a buffering and supporting role.

[0059] Referring back to Figure 3 , Figures 6 to 9 , the hinge 4 is designed in multiple segments, including a plurality of hinge parts 41 that are spaced apart and movably connected, and a gap 401 is formed between any two adjacent hinge parts 41, wherein the gap 401 of the hinge 4 is partially located in the bending center area 11 and partially located in the reverse folding area 12. The arrangement of the gap 401 can avoid the influence of the hinge 4 on the folding of the display panel 5.

[0060] Referring back to Figure 3 and Figure 9 , the orthographic projection of the elastic body 7 on the plane of the display panel 5 covers the orthographic projection of the gap 401 located in the bending center area 11 on the plane of the display panel 5, so that the elastic body 7 can better absorb impact force and better provide support for the display panel 5.

[0061] In another embodiment, as Figures 6 to 8As shown, the orthographic projection of the elastomer 7 on the plane where the display panel 5 is located further covers the orthographic projection of the gap 401 in the reverse folding area 12 on the plane where the display panel 5 is located. This arrangement can further enable the elastomer 7 to better absorb impact force and better support the display panel 5.

[0062] With reference to the accompanying drawings Figure 3 , Figures 6 to 9 In an embodiment, the hinge 4 is designed in five segments, including five hinge sections 41, and four gaps 401 are provided, wherein the middle two gaps 401 are located in the bending center area 11, and the other two gaps 401 are located in the reverse folding area 12.

[0063] With reference to the accompanying drawings Figure 3 , Figures 6 to 9 In an embodiment, the hinge 4 is connected to the support 6 through the back adhesive 3, wherein the orthographic projection of the back adhesive 3 on the plane where the display panel 5 is located is arranged to be spaced from the orthographic projection of the gap 401 on the plane where the display panel 5 is located. This arrangement can avoid the back adhesive 3 affecting the bending of the display panel 5 and the elastomer 7 absorbing impact force.

[0064] The application also provides a display device including the display module 100 in the above embodiments.

[0065] The display device in the embodiments of the application can be any product or component with display function, such as electronic paper, mobile phone, tablet computer, television, display, notebook computer, digital photo frame, or navigator.

[0066] The above description is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the application.
