DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0024] Before introducing the solution of the present application, it should be noted that the drawings of the present application are for illustration only and do not represent the actual proportions of the various structures or regions in the product.

[0025] See also Figure 1 , Figure 2 and Figure 3 The present application provides a display module 100, which includes a bending zone 10. The display module 100 also includes a display panel 5, a support member 6 and an elastomer 7, wherein the support member 6 is arranged on the backlight surface 51 of the display panel 5 for supporting the display panel 5; the elastomer 7 is arranged on the side of the support member 6 away from the display panel 5 and is located in the bending zone 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 to facilitate the folding display of the display module 100. Correspondingly, the display panel 5 can also be a flexible display panel, which can bend as the display module 100 is bent, and the display panel 5 is used to realize the display function of the display module 100. The support member 6 is used to support the display panel 5. 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 and does not affect the display effect. The elastomer 7 is located on the side of the support member 6 away from the display panel 5, at least in the bending area 10. During the use of the display module 100, if it encounters an impact, the elasticity of the elastomer 7 can prevent 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 content, it can be seen that in the present application, by arranging the elastomer 7 in the bending zone 10, a buffering effect can be played when the display module 100 is impacted after falling. Specifically, the impact force generated during the falling process of the display module 100 (especially the impact force generated at the bending position of the hinge 4) can be transmitted to the elastomer 7, and the elastomer 7 buffers and absorbs the impact force, thereby reducing the force transmitted to the display panel 5, protecting the display panel 5, and avoiding damage to the display panel 5. In addition, when the display module 100 is in the unfolded state, the elastomer 7 supports the bending zone 10 to reduce or even avoid the formation of creases.

[0028] During the module process, after the elastic body 7 is formed on the support member 6, the support member 6 and the display panel 5 are assembled together.

[0029] Please continue reading Figures 1 to 3 The display module 100 further includes a T-shaped block 1, a pressure strip 2, a back adhesive 3 and a bending hinge 4; wherein the T-shaped block 1 and the pressure strip 2 are located in the non-display area of ​​the display panel 5 to protect the edge of the display panel 5, wherein the T-shaped block 1 specifically protects the edge of the bending area 10 of the display panel 5, and the pressure strip 2 is located on both sides of the T-shaped block 1. The combination of the pressure strip 2 and the T-shaped block 1 facilitates the flatness of the display surface of the display panel 5. The back 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 to realize the bending function of the display module 100.

[0030] See also Figure 2 , Figure 3 and Figure 4, the bending zone 10 includes a bending center zone 11 and a reflex zone 12 located on both sides of the bending center zone 11, and the elastic body 7 is at least located in the bending center zone 11. Specifically, the bending center zone 11 is located in the central area of ​​the bending zone 10, and its deformation is the largest after bending. When the bending zone 10 is in a water drop shape after bending, the bending zone 10 below the water drop after bending is the bending center zone 11. The display module 100 also includes a non-bending zone 13 outside the bending zone 10, and the display module 100 in the non-bending zone 13 does not bend, and the junction of the non-bending zone 13 and the bending zone 10 is the starting point of the reflex zone 12, and the reflex zone 12 extends from the starting point to the bending center zone 11, and the reflex zone 12 and the bending center zone 11 are arranged at intervals.

[0031] In one embodiment, if Figure 3 As shown, the elastic body 7 may be located only in the bending center area 11 to provide support for the bending center area 11, and can effectively prevent stress from being transferred to the display panel 5 after bending. At the same time, the elastic body 7 can provide sufficient support for the support member 6 in the bending center area 11 to protect the display module 100. In other embodiments, the elastic body 7 may not only be located in the bending center area 11, but may also be further located in the anti-bending area 12.

[0032] In one embodiment, the elastomer 7 is prepared by a supercritical foaming molding process. Specifically, the material of the elastomer 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 elastomer 7 is prepared by a supercritical foaming process, which makes full use of the faster diffusion rate and greater solubility of supercritical carbon dioxide in the polymer. During foaming, the polymer is in a semi-solid state, the molten zone allows the pores to grow, and the unmelted zone provides melt strength and maintains the pore structure. Extremely fast pressure relief induces an extremely high nucleation rate, ensuring the formation of a pore structure with micro-nano size and high pore density.

[0033] Specifically, supercritical foaming is to inject supercritical carbon dioxide or nitrogen or other gases into a special plasticizing device during the injection molding, extrusion and blow molding processes, so that the gas and molten raw materials are fully and evenly mixed / diffused to form a single-phase mixed sol, and then the sol is introduced into the mold cavity or extrusion die to make the sol produce a large pressure drop, so that the gas precipitates to form a large number of bubble nuclei; in the subsequent cooling and molding process, the bubble nuclei inside the sol continue to grow and form, and finally a microporous foamed plastic product is obtained. The pore size can usually be controlled at 0.1-10μm, and the bubble density is generally 109~1015 / cm 3 .

[0034] Supercritical foaming of microporous plastics solves the problem of locking gas better. It not only has some unique properties of general foaming materials, but also has excellent mechanical properties compared with traditional foaming materials. The presence of pores reduces the amount of material used under the same volume, which can reduce the weight of plastic parts and save materials, showing high cost performance such as 5 times the impact strength and fatigue resistance of materials, and 5%-90% reduction in density.

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

[0036] Please continue reading Figure 3 as well as Figure 4 In the first embodiment of the present application, a surface of the support member 6 facing 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 at least arranged in the first recessed area 60 .

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

[0038] In the first embodiment, the thickness of the support member 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 grooving the support member 6, the remaining thickness of the support member 6 is less than or equal to 30 microns. Specifically, the thickness of the support member 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 member 6 located in the bending center area 11, the display module 100 can be easily bent.

[0039] See also Figure 5 and Figure 6 In an application scenario of the first embodiment, the surface of the support member 6 facing away from the display panel 5 is further provided with a second recessed area 61 located in the inflection 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 inflected area 12 and on the surface of the support member 6 away from the display panel 5. In one embodiment, an elastic body 7 is disposed in the second recessed area 61 so that the elastic body 7 has a good support and buffering effect on the inflected area 12, thereby achieving a stable state of the inflected area 12 in the folded state. 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 member 6, but also extends to other areas to achieve a better supporting effect on the support member 6.

[0041] The first recessed area 60 and the second recessed area 61 may include an integral recessed area or may include a plurality of recessed areas.

[0042] In one embodiment, continue to refer to Figure 6 The surface of the elastomer 7 located in the first recessed area 60 and the second recessed area 61 facing the display panel 5 is a convex surface that protrudes toward the display panel 5. This arrangement allows the elastomer 7 to be thickest at the center of the first recessed area 60 and the second recessed area 61, so that the elastomer 7 can better eliminate the creases at the bend of the display panel 5.

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

[0044] In one embodiment, see 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 member 6 is located covers the orthographic projection of the display panel 5 on the plane where the support member 6 is located. Specifically, the elastic body 7 is prepared on the entire surface of the support member 6 away from the display panel 5, and this structure has the advantage of being easy to prepare. In one embodiment, the surface of the elastic body 7 away from the display panel 5 may also be uneven, and part of the elastic body 7 in the bending center area 11 and the inflection area 12 is protruding, which can enhance the supporting effect of the elastic body 7 on the bending center area 11 and the inflection area 12.

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

[0046] Please continue reading Figure 3 In the second application scenario of the first embodiment, the thickness of the elastic body 7 disposed in the first recessed area 60 is greater than the depth of the first recessed area 60 along the direction perpendicular to the plane of the display panel 5. Specifically, the elastic body 7 in the first recessed area 60 protrudes from the first recessed area 60, that is, the elastic body 7 protrudes from the support member 6 away from the surface of 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 protruding from the support member 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 reading Figure 3 , along the direction perpendicular to the plane where the display panel 5 is located, the difference D1 between the maximum thickness of the elastomer 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 elastomer 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 excess thickness between the surface of the elastomer 7 away from the display panel 5 and the surface of the support member 6 away from the display panel 5 can serve as a crease support after the bending center area 11 is recessed, thereby improving the display effect of the display module 100 and preventing the crease from affecting the display effect and user experience.

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

[0049] Please continue reading Figure 3 In one embodiment, the surface of the elastic body 7 facing away from the display panel 5 is a convex surface that protrudes in the direction away from the display panel 5. At this time, the elastic body 7 located in the central area of ​​the bending central area 11 has the largest thickness, and the thickness gradually decreases toward both sides, thereby playing an effective supporting role for the central area of ​​the bending central area 11.

[0050] Continue reading Figure 3 In one embodiment, the surface of the elastic body 7 close to the display panel 5 is a convex surface that protrudes toward the display panel 5. This arrangement can further make the thickness of the elastic body 7 located in the bending center area 11 decrease from the center to the edge position, further playing an effective supporting role for the central area of ​​the bending center area 11. Please continue to read Figure 3In one embodiment, the surface of the support member 6 facing away from the display panel 5 is further provided with a plurality of second grooves 62 located in the inflection area 12, and the orthographic projection of the elastic body 7 on the display panel 5 is arranged at intervals from the orthographic projections of the plurality of second grooves 62 on the display panel 5. Specifically, by providing a plurality of second grooves 62 in the inflection area 12, in the bent state, the bending stress of the support member 6 in the inflection area 12 can be reduced, and the service life of the support member 6 can be increased. At the same time, the elastic body 7 does not cover the second groove 62, and the elastic body 7 and the second groove 62 are used in combination to improve the bending performance of the display module 100.

[0051] See also Figure 7 , Figure 8 and Fig. 9 In the second embodiment of the present application, the surface of the support member 6 away from the display panel 5 is a plane, and the elastic body 7 is stacked with the support member 6. Specifically, the design that the surface of the support member 6 away from the display panel 5 is a plane facilitates the production of the elastic body 7 on the surface of the support member 6 away from the display panel 5, and the elastic body 7 and the support member 6 are stacked, so that the elastic body 7 supports the support member 6 in a bent state, thereby extending the service life of the support member 6.

[0052] See also Figure 7 and Figure 8 , the orthographic projection of the elastic body 7 on the plane where the display panel 5 is located covers the orthographic projection of the support member 6 on the plane where the display panel 5 is located. Specifically, the elastic body 7 covers the surface of the support member 6 away from the display panel 5, so that the support member 6 is effectively protected in the bent state, the buffering performance of the display module 100 is enhanced, and stress impact is reduced or even avoided.

[0053] Please continue reading Figure 7 In the first application scenario of the second embodiment, the surface of the support member 6 facing away from the display panel 5 is continuous and uninterrupted. Specifically, the surface of the support member 6 is continuously arranged to ensure the supporting strength.

[0054] In one embodiment, see Figure 7, the thickness of the support member 6 is less than 30 microns. Specifically, the thickness of the support member 6 can be 5, 10, 15, 20, 25 or 30 microns. In the prior art, the support member 6 with a thickness of less than 30 microns cannot be directly used in the folding display module 100, because the supporting performance is limited. Although the folding performance can be met, the display surface of the display panel 5 will have uneven phenomena such as depression and orange peel. Therefore, the support member 6 with a thickness of less than 30 microns in the prior art cannot be used. In the present application, the support member 6 and the elastomer 7 are stacked and used in combination, so that the elastomer 7 can support the support member 6 both in the bent state and in the unfolded state, meeting the use needs of the folding display module 100. The use of a support member 6 with a small thickness can reduce the volume of the display module 100, and the elastomer 7 can ensure the supporting force of the display module 100, and has a buffering function.

[0055] See also Figure 8 In the second application scenario of the second embodiment, the support member 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 inflection area 12. Specifically, by providing a plurality of first through holes 63 in the bending center area 11 and a plurality of second through holes 64 in the inflection area 12, the folding requirement is met. In the folded state, the provision of the first through holes 63 and the second through holes 64 is conducive to reducing the stress in the bending center area 11 and the inflection area 12, and ensuring the stability of the folded shape.

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

[0057] See also Fig. 9In the third application scenario of the second embodiment, the support member 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 inflection area 12, wherein the orthographic projection of the elastic body 7 on the plane where the display panel 5 is located covers the orthographic projection of the first through hole 63 on the plane where the display panel 5 is located, and the orthographic projection of the elastic body 7 on the plane where the display panel is located is spaced from the orthographic projection of the second groove 62 on the plane where the display panel 5 is located. 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 a first through hole 63 in the bending center area 11 and a second groove 62 in the inflection area 12, the folding needs are met. In the folded state, the provision of the first through hole 63 and the second groove 62 is conducive to reducing the stress in the bending center area 11 and the inflection area 12, and ensuring the stability of the folding shape. 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 arranged at an interval with the orthographic projection of the second groove 62 on the display panel 5, so that the elastic body 7 does not cover the inflected area 12. The design of the first through hole 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, and the elastic body 7 has a light shielding function. When the elastic body 7 covers the bending center area 11, it can prevent light from entering the inside of the display module 100 from the bending hinge 4 and affecting the display effect.

[0058] Among them Fig. 9 In the implementation manner, the elastic body 7 may also 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] Continue reading Figure 3 , Figures 6 to 9 The hinge 4 is designed in multiple sections, including a plurality of hinge parts 41 arranged at intervals and movably connected, and a gap 401 is formed between any two adjacent hinge parts 41, wherein the gap 401 provided in the hinge 4 is partially located in the bending center area 11 and partially located in the reflection area 12. The setting of the gap 401 can prevent the hinge 4 from affecting the folding of the display panel 5.

[0060] Continue reading Figure 3 as well as Fig. 9 The orthographic projection of the elastic body 7 on the plane where the display panel 5 is located covers the orthographic projection of the gap 401 located in the bending center area 11 on the plane where the display panel 5 is located, so that the elastic body 7 can better absorb the impact force and provide better support for the display panel 5.

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

[0062] Continue reading Figure 3 , Figures 6 to 9 In one embodiment, the hinge 4 is designed in five sections, including five hinge parts 41, and is provided with four gaps 401, wherein the middle two gaps 401 are both located in the bending center area 11, and the other two gaps 401 are located in the inflection area 12.

[0063] Continue reading Figure 3 , Figures 6 to 9 In one embodiment, the hinge 4 is connected to the support member 6 through the adhesive 3, wherein the orthographic projection of the adhesive 3 on the plane where the display panel 5 is located is spaced from the orthographic projection of the gap 401 on the plane where the display panel 5 is located. This arrangement can prevent the adhesive 3 from affecting the bending of the display panel 5 and prevent the adhesive 3 from affecting the elastic body 7 from absorbing the impact force.
