DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. And in the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0040] In the related technology, a molded polymer component can be formed around the lower side panel of the cover plate by mold injection, which can improve the impact resistance while taking into account the narrow frame. However, for the mold injection solution, each display product needs to be customized with a special mold. The production process involves mold closing, injection molding, curing, demolding, etc. Each process stage needs to be carried out with a mold, and the whole process is relatively cumbersome. Moreover, such molds generally have a service life of about 100 times, especially in mass production, and their production cost and production rhythm are not advantageous.

[0041] In view of this, the embodiments of the present invention provide a display module, a manufacturing method thereof and a display device, which are used to improve the protection capability of the display module while designing a narrow frame.

[0042] Combination Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a top view of a display module provided by an embodiment of the utility model. Figure 2 For along Figure 1 A schematic diagram of a cross-sectional structure in the direction indicated by MM in FIG. Specifically, the display module includes:

[0043] Cover plate 10, flexible display panel 20 and plastic frame 30;

[0044] Among them, at least one side edge of the flexible display panel 20 has a bending portion 40, the cover plate 10 is located on the light-emitting surface side of the flexible display panel 20, and completely covers the flexible display panel 20 and the plastic frame 30; the plastic frame 30 is at least arranged around the edge of the flexible display panel 20, and at least covers the side wall of the flexible display panel 20.

[0045] In the specific implementation process, the display module provided by the embodiment of the utility model includes a cover plate 10, a flexible display panel 20 and a plastic frame 30; wherein, at least one side edge of the flexible display panel 20 has a bending portion 40. Exemplarily, the flexible display panel 20 is a two-curved screen with bending portions 40 on both sides. Exemplarily, the flexible display panel 20 is a four-curved screen with bending portions 40 on all four sides. Moreover, the cover plate 10 is located on the light-emitting surface side of the flexible display panel 20 and completely covers the flexible display panel 20 and the plastic frame 30, so that the flexible display panel 20 can be protected to a certain extent by the cover plate 10. Exemplarily, the flexible display panel 20 is retracted inward by a certain range compared to the cover plate 10. In addition, the plastic frame 30 is at least arranged around the edge of the flexible display panel 20 and at least covers the side wall of the flexible display panel 20. In this way, the plastic frame 30 can be arranged at least around the edge of the flexible display panel 20, and the plastic frame 30 can at least cover the side wall of the flexible display panel 20. In this way, the plastic frame 30 can prevent water and oxygen from invading the display module along the side wall of the flexible display panel 20, thereby causing corrosion damage to the flexible display panel 20, thereby improving the yield of the display module and enhancing the impact resistance of the display module.

[0046] In the embodiment of the present invention, the plastic frame 30 can be arranged in the following ways, but is not limited to the following ways.

[0047] In one exemplary embodiment, the plastic frame 30 includes at least one retaining wall 50 disposed around the display area A.

[0048] In a specific implementation process, the plastic frame 30 includes at least one retaining wall 50 arranged around the display area A. The at least one retaining wall 50 may be one or more. In practical applications, the specific number of the at least one retaining wall 50 may be set as required, which is not limited here. Exemplarily, each retaining wall may be prepared by dispensing glue, thereby realizing rapid preparation of the plastic frame 30.

[0049] In one exemplary embodiment, in combination Figures 3 to 8 As shown, the glue frame 30 includes a plurality of retaining walls arranged around the display area A, and a filler 60 located between two adjacent retaining walls. Each retaining wall is formed after a first glue material is solidified, and the filler 60 is formed after a second glue material is solidified. The viscosity of the first glue material is greater than the viscosity of the second glue material.

[0050] In the specific implementation process, the glue frame 30 includes a plurality of retaining walls arranged around the display area A, and a filler 60 located between two adjacent retaining walls. In practical applications, a plurality of retaining walls can be formed by 3D printing or dispensing, and the required glue material is filled between the retaining walls to form the required filler 60. Among them, each retaining wall is formed after the first glue material is cured, and the filler 60 is formed after the second glue material is cured. The viscosity of the first glue material is greater than the viscosity of the second glue material. Exemplarily, the viscosity range of the first glue material is 10 5 mPa.S~10 7 mPa.S, and the viscosity of the second adhesive is in the range of 0 to 1000 mPa.S. For example, the first adhesive may be an acrylic or epoxy resin adhesive material, and its viscosity may be 10 5 mPa.S, can be a translucent paste, the curing depth is greater than or equal to 1.5mm, and the hardness after curing is greater than or equal to 60D; the second glue material can also be an acrylic or epoxy resin glue material, the viscosity can be 1000mPa.S, can be a translucent liquid, the surface drying time is less than 5s under ultraviolet (UV) irradiation, and the hardness after curing is greater than or equal to 60D. In this way, in the actual preparation process, the preparation of the glue frame 30 can be achieved without adding additional molds, and the overall preparation efficiency is high.

[0051] In one exemplary embodiment, Figure 3 As shown, the plurality of retaining walls include a first retaining wall 51 disposed around the side wall of the flexible display panel 20, and a second retaining wall 52 close to the outermost edge of the cover plate 10. In addition, in this exemplary embodiment, the side surface of the plastic frame 30 close to the outermost edge of the cover plate 10 is flush with the corresponding side surface of the cover plate 10. In this way, the assembly convenience of the plastic frame 30 and the subsequent middle frame is improved.

[0052] In one exemplary embodiment, Figure 4 As shown, the display module also includes a heat sink 70 on the side away from the light-emitting surface of the flexible display panel 20, the heat sink 70 is completely covered by the flexible display panel 20, and the multiple retaining walls also include a third retaining wall 53 arranged around the side wall of the heat sink 70. In this way, the heat sink 70 ensures the heat dissipation efficiency of the display module and improves the performance of the display device. Exemplarily, the heat sink 70 can be a composite heat dissipation structure composed of mesh glue, foam and copper foil.

[0053] In one exemplary embodiment, Figure 5As shown, the plurality of retaining walls also include a fourth retaining wall 54 located on the inner surface of the heat sink 70 and close to the side wall of the heat sink 70. In this way, while taking into account the heat dissipation efficiency of the display module, it is possible to effectively prevent water and oxygen from invading the interior of the display module along the heat sink 70 and the side wall of the flexible display panel 20, thereby causing corrosion damage to the display module, thereby improving the yield of the display module.

[0054] Still combined Figure 4 and Figure 5 In the exemplary embodiment shown, at the corresponding position of the bending portion 40, the plurality of retaining walls also include a fifth retaining wall 55 arranged at the corresponding position of the inner surface shape change point of the plastic frame 30. It should be noted that the inner surface shape change point of the plastic frame 30 can be a concave point of the corresponding curved surface of the inner surface, or a convex point of the corresponding curved surface of the inner surface; in actual application, the concave point can be one or more; the convex point can be one or more, and the specific number setting can be limited according to needs. Figure 5 Taking the inner surface shape change point N as an example, the point is a convex point of the corresponding inner surface, and the distance between it and the flat portion connected to the bending portion 40 in the cover plate 10 is greater than the distance between the position adjacent to the point N in the inner surface and the flat portion. Of course, in actual application, the inner surface shape of the plastic frame 30 can also be set according to actual needs, which is not limited here.

[0055] In one exemplary embodiment, still in combination Figure 4 and Figure 5 As shown, the inner surface of the plastic frame 30 has the same curvature as the inner surface of the flexible display panel 20 and the inner surface of the cover plate 10. Accordingly, the curvature of the inner surface of the plastic frame 30 is consistent with the curvature of the inner surface of the cover plate 10, which facilitates the subsequent assembly of the display module and the middle frame.

[0056] It should be noted that in Figure 4 and Figure 5 In the exemplary embodiment shown, the plastic frame 30 needs to cover the step of the heat sink 70 and extend at least 0.3 mm beyond the edge of the heat sink 70, and the thickness of the portion of the plastic frame 30 covering the heat sink 70 is at least 0.2 mm. In this way, while ensuring the heat dissipation efficiency of the display module, the supporting and protective performance of the plastic frame 30 on the display module is improved, thereby ensuring the yield of the display module.

[0057] In the embodiment of the present invention, the degree of change of the curvature of a specific area of ​​the inner surface of the plastic frame 30 is positively correlated with the arrangement density of the retaining walls in the specific area.

[0058] In the specific implementation process, the greater the degree of change in the inner surface curvature of the rubber frame 30, the more complex the shape of the rubber frame 30; in actual applications, the setting density of the retaining wall can be increased at the position of the complex shape, so as to realize the preparation of the rubber frame 30 of the desired shape.

[0059] In one exemplary embodiment, a protective space 80 for avoiding at least one component is provided on the inner surface of the plastic frame 30. The at least one component may be one or more, which is not limited here. In practical applications, the avoidance space of the relevant components can be provided as needed, thereby improving the performance of the display module while taking into account the protection and support of the plastic frame 30.

[0060] exist Figure 6 In the exemplary embodiment shown, the inner surface of the plastic frame 30 is provided with a protective space 80 for avoiding the speaker, the packaging thickness of the plastic frame 30 at the corresponding position of the protective space 80 is reduced, and the corresponding form of the required protective space 80 can be obtained by increasing the density of the setting of the retaining wall at this position. It should be noted that in order to more clearly illustrate the structure of the plastic frame 30 at the corresponding position of the protective space 80, Figure 6 FIG. 4 is a schematic diagram showing only one structure of the display module in the corresponding area of ​​the bending portion 40 .

[0061] In an embodiment of the utility model, the four side edges of the flexible display panel 20 all have the bending portion 40, and the display module also includes a heat sink 70 located on the side of the flexible display panel 20 away from the light emitting surface, the heat sink 70 is completely covered by the flexible display panel 20, and the at least one retaining wall 50 is one, the retaining wall is arranged around the side wall of the heat sink 70, the retaining wall and the inner surface of the cover plate 10 away from the display area A to form a first accommodating space 90, a filler 60 is arranged in the first accommodating space 90, the retaining wall is formed after the first adhesive is cured, and the filler 60 is formed after the second adhesive is cured, and the viscosity of the first adhesive is greater than the viscosity of the second adhesive.

[0062] exist Figure 7In the exemplary embodiment shown, the flexible display panel 20 can be a four-curved screen with a bending portion 40 on all four side edges; the display module also includes a heat sink 70 located on the side of the flexible display panel 20 away from the light emitting surface, and the heat sink 70 is completely covered by the flexible display panel 20, and only one retaining wall is provided around the side wall of the heat sink 70. In addition, the retaining wall and the side of the inner surface of the cover plate 10 away from the display area A enclose a first accommodating space 90, and a filler 60 is provided in the first accommodating space 90. In the actual preparation process, the filler 60 can be more conveniently prepared in the first accommodating space 90. The retaining wall is formed after the first adhesive is cured, and the filler 60 is formed after the second adhesive is cured, and the viscosity of the first adhesive is greater than the viscosity of the second adhesive. Exemplarily, the viscosity range of the first adhesive is 10 5 mPa.S~10 7 mPa.S, and the viscosity of the second adhesive material ranges from 0 to 1000 mPa.S. In this way, the first adhesive material with a relatively large viscosity can be used to solidify the required retaining wall, and the second adhesive material with a relatively small viscosity can be used to solidify the required filler 60, and the entire preparation process is highly efficient.

[0063] Still combined Figure 7 In the exemplary embodiment shown, the end of the retaining wall 50 facing away from the cover plate 10 is flush with the outermost edge of the inner surface of the cover plate 10 and the inner surface of the filler 60. In the actual preparation process, the second adhesive can be effectively prevented from overflowing from the first accommodating space 90, thereby improving the preparation efficiency of the display module.

[0064] In one of the exemplary embodiments, the four side edges of the flexible display panel 20 all have the bending portion 40, and the display module also includes a heat sink 70 located on the side of the flexible display panel 20 away from the light-emitting surface, at least one side of the heat sink 70 completely exceeds or covers the side corresponding to the flexible display panel 20, and the heat sink 70 is completely covered by the cover plate 10; the side wall of the flexible display panel 20, the side wall of the heat sink 70 and the side of the inner surface of the cover plate 10 away from the display area A form a second accommodating space 91, and the rubber frame 30 is accommodated in the second accommodating space 91.

[0065] exist Figure 8In the exemplary embodiment shown, the flexible display panel 20 can be a four-curved screen with bent portions 40 on all four side edges; the display module also includes a heat sink 70 located on the side of the flexible display panel 20 away from the light emitting surface, one side of the heat sink 70 completely exceeds the side correspondingly arranged on the flexible display panel 20, and accordingly, the flexible display panel 20 is retracted compared to the edge of the heat sink 70. Moreover, the heat sink 70 is completely covered by the cover plate 10, and accordingly, the heat sink 70 is retracted compared to the edge of the cover plate 10. In addition, the side wall of the flexible display panel 20, the side wall of the heat sink 70 and the side of the inner surface of the cover plate 10 away from the display area A form a second accommodation space 91, and the plastic frame 30 is accommodated in the second accommodation space 91. In the actual preparation process, the second accommodation space 91 for accommodating materials related to the plastic frame 30 can be directly formed with the help of the heat sink 70 and the cover plate 10, thereby improving the preparation efficiency of the plastic frame 30.

[0066] Still combined Figure 8 In the exemplary embodiment shown, the outermost edge of the inner surface of the heat sink 70 is flush with the outermost edge of the inner surface of the cover plate 10 and the inner surface of the plastic frame 30. In the actual preparation process, the plastic material used to prepare the plastic frame 30 can be effectively prevented from overflowing from the second accommodating space 91, thereby improving the preparation efficiency of the display module.

[0067] It should be noted that, in the specific implementation process, the display module may include other film layer structures in addition to the above-mentioned related film layers. Exemplarily, the display module also includes a glue layer 92 located between the cover plate 10 and the flexible display panel 20, through which the cover plate 10 and the flexible display panel 20 can be bonded together. Exemplarily, the glue layer 92 can be an optically clear adhesive (Optically Clear Adhesive, OCA) or an optical resin material (Optically Clear Resin, OCR). The display module also includes a back film 93 located between the heat sink 70 and the flexible display panel 20, thereby ensuring the supporting performance of the flexible display panel 20. Of course, other film layer structures can also be set according to actual application needs. The specific settings can be implemented with reference to relevant technologies, which will not be described in detail here.

[0069] In the specific implementation process, the structure of the middle frame 200 can be set accordingly according to the specific form of the plastic frame. Figure 5 The display module 100 shown in FIG. Fig. 9 As shown, in the area corresponding to the bending portion 40, the middle frame 200 includes a main body 201 and a branch portion 202 connected in sequence, one end of the main body 201 is in direct contact with the side surface of the cover plate 10 and the side surface of the plastic frame 30 close to the outermost edge of the cover plate 10, and the contact surface is a plane, and the branch portion 202 is in direct contact with the inner surface of the plastic frame 30, and the curvature of the branch portion 202 is the same as the curvature of the inner surface of the plastic frame 30.

Fig.10 As shown, in the area corresponding to the bending portion 40, the middle frame 200 includes a first branch 210 and a second branch 220 connected in sequence, one end of the first branch 210 directly contacts the side surface of the cover plate 10, and one end of the second branch 220 directly contacts the side surface of the filler 60.

[0071] Of course, in addition to setting the relationship between the display module 100 and the middle frame 200 in the above-mentioned manner, corresponding related structures can also be set according to actual applications, which will not be described in detail here.

[0072] Since the principle of solving the problem of the display device is similar to that of the aforementioned display module, the implementation of the display device can refer to the implementation of the aforementioned display module, and the repeated parts will not be repeated.
