[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] This application provides a support structure for a display module. For a clearer understanding of the specific structure of the support structure for the display module, please refer to... Figure 1 , Figure 1 This is a schematic diagram of a support structure provided in an embodiment of this application. The support structure 000 of the display module 001 may include: a housing 100, a protective film 200, and an adhesive layer 300.

[0043] like Figure 1 As shown, the housing 100 in the support structure 000 of the display module 001 may have a receiving cavity K, and the display module 001 may be located in the receiving cavity K of the housing 100.

[0044] Please refer to Figure 1 and Figure 2 , Figure 2This is a schematic diagram of a support structure excluding a housing provided in an embodiment of this application. The protective film 200 in the support structure 000 can be located on the light-emitting side of the display module 001. The protective film 200 in the support structure 000 may include: a protective film body 201 covering the front side of the display module 001, and a connecting portion 202 connected to the edge of the protective film body 201 in the protective film 200. The connecting portion 202 in the protective film 200 can be connected to the housing 100 in the support structure 000. It should be noted that the front side of the display module 001 refers to the plane where the display surface of the display module 001 is located.

[0045] The adhesive layer 300 in the support structure 000 can be located between the protective film 200 and the display module 001. The protective film body 201 in the protective film 200 can be bonded to the front side of the display module 001 through the adhesive layer 300, and the adhesive layer 300 can be debonded under the illumination of the target light.

[0046] In this application, the unadhesive layer 300 in the support structure 000 can be adhesive, so that the unadhesive layer 300 in the support structure 000 can bond the front of the display module 001 to the protective film body 201 in the protective film 200. In this way, the protective film body 201 in the protective film 200 can protect the front of the display module 001 so that the front of the display module 001 will not be scratched.

[0047] Furthermore, since the connecting portion 202 in the protective film 200 is connected to the housing 100, and the connecting portion 202 in the protective film 200 is connected to the edge of the protective film body 201, the display module 001 can be fixed within the receiving cavity K of the housing 100 via the unadhesive layer 300 and the protective film 200. Therefore, during the production and transportation of the display module 001, the display module 001, fixed within the receiving cavity K of the housing 100, will not shift, preventing damage from impacts. Thus, the supporting structure 000 can protect the display module 001 from damage, resulting in higher reliability of the terminal devices manufactured based on this display module 001.

[0048] In this application, since the unadhesive layer 300 in the supporting structure 000 can unadhere under the irradiation of the target light, when the display module 001 needs to be processed subsequently, irradiating the unadhesive layer 300 with the target light can reduce the adhesiveness of the unadhesive layer 300, for example, it can make the unadhesive layer 300 lose its adhesiveness. This allows the unadhesive layer 300, along with the protective film 200, to be peeled off from the front side of the display module 001, so that the display module 001 can proceed to subsequent processing steps. For example, the target light here can be ultraviolet light and / or laser light.

[0049] In summary, this application provides a support structure for a display module, comprising: a housing, a protective film, and a release film. The release film in the support structure can be adhesive, allowing it to bond the front of the display module to the protective film body within the protective film. This protects the front of the display module from scratches. Furthermore, since the connecting portion of the protective film is connected to the housing and its edge is also connected to the protective film body, the display module can be fixed within the housing cavity of the housing using the release film and the protective film. Therefore, during production and transportation, the display module, fixed within the housing cavity, will not shift, preventing damage from impacts. Thus, the support structure effectively protects the display module from damage, resulting in higher reliability of terminal devices manufactured based on this display module.

[0050] Optional, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a box provided in an embodiment of this application. Figure 4 This is a schematic diagram of another support structure provided in an embodiment of this application. The box 100 in the support structure 000 of the display module 001 may include: a support box 101 and a cover 102.

[0051] Here, the carrier box 101 in the box body 100 may have a receiving cavity K and an opening O communicating with the receiving cavity K, and the cover 102 in the box body 100 may be connected to the carrier box 101 at the opening O.

[0052] Among them, such as Figure 4 As shown, at least a portion of the connecting portion 202 in the protective film 200 can extend outside the receiving cavity K of the carrier box 101, and the portion of the connecting portion 202 in the protective film 200 extending outside the receiving cavity K of the carrier box 101 can be clamped by the connected carrier box 101 and cover 102. In this way, in the overlapping direction of the carrier box 101 and cover 102, that is, in the direction perpendicular to the display module 001, by the clamping of the portion of the connecting portion 202 in the protective film 200 extending outside the receiving cavity K of the carrier box 101 by the connected carrier box 101 and cover 102, it can be ensured that the display module 001, which is bonded to the protective film body 201 in the protective film 200, is fixed inside the receiving cavity K of the box 100, so that the display module 001 will not be displaced in the direction perpendicular to the display module 001.

[0053] Please refer to the following in this application: Figure 4 and Figure 5 , Figure 5 This is a schematic diagram of another box structure provided in an embodiment of this application. The carrier box 101 in the box 100 may include: a carrier box body 1011 having an accommodating cavity K, and a first connector 1012 fixedly connected to the edge of the carrier box body 1011.

[0054] The cover 102 in the box 100 may include: a cover body 1021 covering the opening O of the carrier box 101, and a second connector 1022 fixedly connected to the edge of the cover body 1021.

[0055] The first connector 1012 in the carrier box 101 can be connected to the second connector 1022 in the cover 102. Here, after the first connector 1012 in the carrier box 101 and the second connector 1022 in the cover 102 are connected, a sealed accommodating cavity K can be formed between the carrier box 101 and the cover 102, so that the front of the display module 001 located inside this accommodating cavity K can be protected by the cover 102, and the back and sides of the display module 001 located inside this accommodating cavity K can be protected by the carrier box 101.

[0056] In this application, the portion of the connecting portion 202 in the protective film 200 that extends outside the accommodating cavity K of the carrier box 101 can be located between the first connecting member 1012 in the carrier box 101 and the second connecting member 1022 in the cover 102.

[0057] It should be noted that, as Figure 5 As shown, in the stacking direction of the carrier box 101 and the cover 102, the first connector 1012 in the carrier box 101 and the second connector 1022 in the cover 102 can have an overlapping area with a width of L. The portion of the connector 202 in the protective film 200 that extends outside the accommodating cavity K and is located between the overlapping areas of the first connector 1012 and the second connector 1022 can be clamped. For this purpose, the portion of the connector 202 in the protective film 200 that extends outside the accommodating cavity K of the carrier box 101 can be clamped by the connected carrier box 101 and cover 102, which prevents the display module 001, which is bonded to the protective film body 201 in the protective film 200, from displacement in a direction perpendicular to the display module 001.

[0058] Optional, please refer to Figure 6 and Figure 7 , Figure 6 This is a top view of a protective film provided in an embodiment of this application. Figure 7 This is a schematic diagram of the structure of a protective film provided in an embodiment of this application. The connecting portion 202 in the protective film 200 may have multiple first through holes S1.

[0059] like Figure 4 and Figure 5 As shown, the housing 100 in the supporting structure 000 may further include a plurality of support columns 103 connected to the first connector 1012 in the supporting housing 101 and the second connector 1022 in the cover 102. The plurality of support columns 103 in the housing 100 may correspond one-to-one with a plurality of first through holes S1 in the connecting portion 202 of the protective film 200, and each first through hole S1 in the connecting portion 202 may be fitted onto the corresponding support column 103.

[0060] Thus, through the cooperation of each first through hole S1 in the connecting portion 202 with the corresponding support post 103, the connecting portion 202 in the protective film 200 can be connected to the housing 100. Therefore, on the horizontal plane parallel to the display module 001, the display module 001, which is bonded to the protective film body 201 in the protective film 200, will not shift on the horizontal plane parallel to the display module 001. In this way, the display module 001 can be more securely fixed within the receiving cavity K of the housing 100.

[0061] It should be noted that, please refer to Figure 4 , Figure 6 and Figure 7 The first through hole S1 of the connecting part 202 in the protective film 200 can be a circular hole, and the diameter of the first through hole S1 can be R1. The support post 103 in the box 100 that mates with the first through hole S1 can be a cylindrical protrusion, and the bottom diameter of the support post 103 can be R2.

[0062] Here, the following relationship can be satisfied between the diameter R1 of the first through hole S1 and the bottom diameter R2 of the support column 103:

[0063]

[0064] Where a represents the machining tolerance of the box 100, and b represents the opening position tolerance of the connecting portion 202 in the protective film 200. Thus, the diameter R1 of the first through hole S1 of the connecting portion 202 in the protective film 200 can be larger than the diameter R2 of the support column 103 in the box 100. Therefore, the first through hole S1 of the connecting portion 202 in the protective film 200 can be more easily fitted onto the corresponding support column 103.

[0065] In this application, as Figure 6 As shown, the protective film 200 in the bearing structure 000 may include two connecting portions 202 arranged opposite to each other. The protective film body 201 in the protective film 200 may be located between the two connecting portions 202, and the two side edge portions of the protective film body 201 arranged opposite to each other in the protective film 200 may be connected to the two connecting portions 202 respectively.

[0066] Each connecting portion 202 in the protective film 200 may have at least two first through holes S1. For example, the at least two first through holes S1 in each connecting portion 202 may be arranged in a row, and the arrangement direction of this row of first through holes S1 may be parallel to the length direction of the connecting portion 202.

[0067] In this way, each connecting portion 202 in the protective film 200 can be sleeved onto the corresponding support post 103 in the housing 100 through the corresponding first through hole S1. Therefore, the oppositely arranged portions on both sides of the protective film 200 can be connected to the housing 100 and can be clamped by the first connecting portion 1012 in the housing 101 and the second connecting portion 1021 in the cover 102. Thus, after the oppositely arranged portions of the protective film 200 are clamped, it can be ensured that the protective film 200 can be stretched in a direction parallel to the display surface of the display module 001, thereby ensuring that the display module 001, which is bonded to the protective film body 201 in the protective film 200, can be more securely fixed within the receiving cavity K of the housing 100.

[0068] It should be noted that since the display surface of the display module 001 is usually rectangular, the protective film 200 in the supporting structure 000 can also be a rectangular protective film. Correspondingly, as... Figure 6 As shown, the protective film body 201, which is adhered to the front of the display module 001, can also be rectangular. Here, to ensure that the display module 001 is more securely fixed within the housing cavity K of the box 100 via the protective film 200, the two connecting portions 202 in the protective film 200 can be distributed on opposite sides of the protective film body 201 along its long side. That is, the two connecting portions 202 in the protective film 200 can be fixedly connected to the two opposite short edges of the protective film body 201, respectively.

[0069] In this configuration, along the long side of the display module 001, both connecting portions 202 in the protective film 200 protrude from the display module 001. Along the short side of the display module 001, the side surface of the protective film body 201 in the protective film 200 can be flush with the side surface of the display module 001; that is, the side surface of each long side of the protective film body 201 is flush with the corresponding long side surface of the display module 001. Of course, along the short side of the display module 001, the protective film body 201 in the protective film 200 can also protrude from the display module 001; this embodiment does not limit this.

[0070] Optional, such as Figure 7As shown, the unadhesive layer 300 in the support structure 000 may include: a first colloid 301 distributed on the protective film body 201 in the protective film 200, and a second colloid 302 distributed on the connecting portion 202 in the protective film 200.

[0071] In this application, as Figure 7 As shown, the supporting structure 000 may further include an auxiliary membrane 400. The auxiliary membrane 400 in the supporting structure 000 can be bonded to the connecting portion 202 via a second colloid 302.

[0072] In this way, the first adhesive 301 in the de-adhesive layer 300 can bond the protective film body 201 to the display film assembly 001, so that the protective film body 201 can protect the front side of the display module 00. The auxiliary film 400 in the support structure 000 can protect the second adhesive 302 distributed on the connecting portion 202 in the protective film 200, so that the adhesive second adhesive 302 will not come into contact with other components in the display module 001, and avoid damage to other components in the display module 001 caused by the second adhesive 302.

[0073] In this application, as Figure 7 As shown, when the connecting portion 202 in the protective film 200 can have multiple first through holes S1, the second colloid 302 in the unadhesive layer 300 can have multiple second through holes S2 communicating with the first through holes S1 in the connecting portion 202, and the auxiliary film 400 in the support structure 000 can have multiple third through holes S3 corresponding to the multiple second through holes S2 in the second colloid 302. Thus, the first through holes S1 in the connecting portion 202 of the protective film 200, the second through holes S2 in the second colloid 302 of the unadhesive layer 300, and the third through holes S3 in the auxiliary film 400 can all be fitted onto the support pillars 103 in the corresponding housing 100, thereby allowing the protective film 200 to be stably connected to the housing 100.

[0074] It should be noted that the protective film 200, the de-adhesion layer 300, and the auxiliary film 400 in the load-bearing structure 000 are usually integrally formed composite structures.

[0075] For example, please refer to Figure 8 , Figure 8 This is a schematic diagram illustrating the cutting and processing of a composite structure according to an embodiment of this application. Here, the composite structure typically refers to a composite film structure composed of a first film 01a, an adhesive layer 01b, and a second film 01c stacked together. After cutting and processing this composite film structure, it can be bonded to the front side of the display module 001, thus obtaining a protective film 200, an adhesive release layer 300, and an auxiliary film 400 on the front side of the display module 001.

[0076] For example, the first film 01a can be used as the protective film 200 in the support structure 000, and the colloidal layer 01b can be used as the debonding layer 300 in the support structure 000. Then, the second film 01c can be cut according to the size of the display module 001 to remove the middle portion 01c1 in the second film 01c, and the edge portions 01c2 on both sides of the second film 01c can be used as the auxiliary film 400 in the support structure 000.

[0077] Furthermore, after cutting the middle portion 01c1 of the second film 01c, the edge portion 01c2 of the second film 01c can be perforated to form corresponding third vias S3, second vias S2, and first vias S1. Subsequently, the portion of the adhesive layer 01b exposed from the middle portion 01c1 of the second film 01c can be bonded to the front side of the display module 001, thus obtaining the protective film 200, the release layer 300, and the auxiliary film 400 on the front side of the display module 001.

[0078] Please refer to the following in this application: Figure 9 , Figure 9 This is a schematic diagram of another load-bearing structure without a housing provided in an embodiment of this application. The display module 001 may include: a display panel 011, and a driving component 012 that is bound and connected to the display panel 011.

[0079] It should be noted that, in this application embodiment, the display panel 011 can be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, or a micro-LED display panel. This application embodiment does not limit this. The following embodiments are illustrative examples using an OLED display panel as an example.

[0080] The protective film body 201 of the protective film 200 can at least cover the display area of ​​the display panel 011, so that the protective film body 201 of the protective film 200 can protect the display panel 011 in the display module 001. The connecting portion 202 of the protective film 200 can at least cover the driving component 012, so that the connecting portion 202 of the protective film 202 can protect the driving component 012 in the display module 001.

[0081] In addition, the auxiliary film 400 in the support structure 000 can protect the second colloid 302 distributed on the connection portion 202 in the protective film 200, so as to prevent the drive component 012 covered by the connection portion 202 in the protective film 200 from being adhered by the second colloid 302, thereby ensuring that the second colloid 302 will not cause damage to the drive component 012.

[0082] Optional, such as Figure 9 As shown, when the connecting portion 202 in the protective film 200 has a first through hole S1, in the direction parallel to the display surface of the display panel 011, the maximum distance D1 between the outermost edge of the driving component 012 in the display module 001 away from the display panel 011 and the protective film body 201 in the protective film 200 can be less than the minimum distance D2 between the first through hole S1 of the connecting portion 202 in the protective film 200 and the protective film body 201. In this way, it can be ensured that the connecting portion 202 in the protective film 200 can completely cover the driving component 012 in the display module 001, so that the driving component 102 can be completely protected.

[0083] In this application, as Figure 9 As shown, the display module 001 may further include: at least one optical functional layer 013 located between the display panel 011 in the display module 001 and the protective film body 201 in the protective film 200, and a support back plate 014 on the side of the display panel 011 opposite to the protective film body 201.

[0084] It should be noted that, as Figure 9 As shown, the display module 001 may further include a double-sided adhesive 015 located between the display panel 011 and the support back plate 014. Both sides of the double-sided adhesive 015 in the display module 001 can be adhesive, thus allowing the side of the support back plate 014 facing the display panel 011 in the display module 001 to be connected to the back side of the display panel 011 via the double-sided adhesive 015. Here, the back side of the display panel 011 refers to the plane of the display module 001 that faces away from the display surface.

[0085] It should be noted that the optical functional layer 013 in the display module 001 may include at least one of the following: privacy film 0131, privacy protective film 0132, and polarizer 0133.

[0086] Please refer to this. Figure 10 , Figure 10This is a schematic diagram of another support structure without a housing provided in this application embodiment. When the optical functional layer 013 includes both a privacy film 0131 and a privacy protective film 0132, the privacy protective film 0132 can be located on the side of the privacy film 0131 facing away from the display panel 011. The privacy film 0131 enables the display module 001 to have a privacy function, allowing only the user of the display device integrating this display module 001 to view the displayed image, while bystanders next to the user cannot view the image displayed on the display device. The privacy protective film 0132 protects the privacy film 0131, ensuring that the display module 001 integrating the privacy film 0131 has a better privacy effect.

[0087] Please refer to Figure 11 , Figure 11 This is a schematic diagram of a support structure without a housing, provided in another embodiment of this application. When the optical functional layer 013 includes both a privacy film 0131 and a polarizer 0133, the polarizer 0133 can be located between the privacy film 0131 and the display panel 011. The polarizer 0133 can reduce the reflectivity of the display panel 011 to ambient light, thereby ensuring a better display effect.

[0088] It should be noted that, in the case where the optical functional layer 013 includes a polarizer 0133, the optical functional layer 013 may also include an optical adhesive layer 0134 located between the display panel 011 and the polarizer, which can be used to bond the display panel 011 and the polarizer 0133.

[0089] In summary, this application provides a support structure for a display module, comprising: a housing, a protective film, and a release film. The release film in the support structure can be adhesive, allowing it to bond the front of the display module to the protective film body within the protective film. This protects the front of the display module from scratches. Furthermore, since the connecting portion of the protective film is connected to the housing and its edge is also connected to the protective film body, the display module can be fixed within the housing cavity of the housing using the release film and the protective film. Therefore, during production and transportation, the display module, fixed within the housing cavity, will not shift, preventing damage from impacts. Thus, the support structure effectively protects the display module from damage, resulting in higher reliability of terminal devices manufactured based on this display module.

[0090] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.

[0091] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0092] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
