Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a display module and an electronic equipment. Background Art

[0002] In order to expand the functions of electronic devices, the display area of ​​the display module of electronic devices is getting larger and larger, and improving the screen-to-body ratio has become an important development direction of electronic devices. However, at the same time, the edge packaging area of ​​the display module is getting smaller and smaller, which can easily lead to problems such as black spots and flowery screens.

[0003] In the related art, the display module usually includes a stacked display panel and a polarizer. Both the display panel and the polarizer are provided with openings, which are opposite to the camera module. In addition, the display panel is provided with a packaging structure, which packages the camera module. Since the polarizer is prone to shrinkage during the test operation of the display module under high temperature and high humidity conditions, the polarizer needs to be stretched subsequently, and the polarizer is subjected to the stretching force. At the same time, since the polarizer is connected to the display panel, the stretching force of the polarizer will produce a shearing force on the display panel, and the shearing force is likely to damage the packaging structure. Elements such as iodine and potassium in the polarizer may penetrate into the damaged packaging structure, resulting in packaging failure, causing the display panel to be corroded by water and oxygen, and problems such as black spots and flowery screens. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a display module and an electronic device, which can solve the problem that the packaging structure of the display panel in the related art is prone to packaging failure.

[0005] In a first aspect, an embodiment of the present application provides a display module, wherein the display module is provided with a non-display area, the display module comprises a stacked display panel and a polarizer, a portion of the display panel corresponding to the non-display area comprises a packaging structure, the packaging structure is provided with a first opening, The polarizer is provided with a break, and the polarizer is divided into a first polarization part and a second polarization part through the break, the first polarization part is provided with a second opening, the first opening is opposite to the second opening, and the second polarization part is located at the periphery of the first polarization part.

[0006] In a second aspect, an embodiment of the present application further provides an electronic device, comprising a device housing and the above-mentioned display module, wherein the display module is disposed in the device housing.

[0007] In the embodiment of the present application, the first polarizing portion and the second polarizing portion are separated by a fracture. When the polarizer is stretched, at least part of the stretching force borne by the second polarizing portion will not be transmitted to the first polarizing portion, so that the stretching force borne by the first polarizing portion is reduced. Since the first opening is opposite to the second opening, and the first polarizing portion with the second opening is opposite to the packaging structure with the first opening, the shear force applied by the first polarizing portion to the packaging structure is also reduced, and the packaging structure is not easily damaged. Elements such as iodine and potassium in the polarizer are also not easy to penetrate into the packaging structure, thereby avoiding packaging failure, thereby preventing the display panel from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The display module and the electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-Figure 9 The display module disclosed in the embodiment of the present application is applied to an electronic device, and the display module plays a display function. The display module is provided with a non-display area, which is located at the edge of the display module and is used for packaging. The display module is also provided with a display area, and the non-display area is arranged around the display area.

[0014] refer to Figure 1 and Figure 2As shown, the display module includes a stacked display panel 200 and a polarizer 300, wherein the display panel 200 is used for display function, and the polarizer 300 is used for filtering. The polarizer 300 separates the incident light, wherein a part of the light passes through, and the other part of the light is concealed by absorption, reflection, scattering, etc. The display panel 200 and the polarizer 300 are respectively provided with a first opening 200a and a second opening 300a, the first opening 200a is opposite to the second opening 300a, and the first opening 200a and the second opening 300a are respectively opposite to the camera module, and the light enters the camera module through the first opening 200a and the second opening 300a, so that the camera module realizes the camera function. Among them, the first opening 200a and the second opening 300a can be a circular hole, a square hole, etc. structure, and the shape and size of the first opening 200a and the second opening 300a are respectively the same. In this way, the camera module is packaged in the non-display area, and the first opening 200a and the second opening 300a are both located in the non-display area to prevent the first opening 200a and the second opening 300a from affecting the display effect of the display area.

[0015] The portion of the display panel 200 corresponding to the non-display area includes a packaging structure 210, and the packaging structure 210 is provided with a first opening 200a. Optionally, the packaging structure 210 can be a circular ring structure, and the first opening 200a is a circular hole, or the packaging structure 210 is a square ring structure, and the first opening 200a is a square hole. The packaging structure 210 surrounds the first opening 200a. The embodiment of the present application does not limit the shape of the packaging structure 210 and the first opening 200a. In this way, the camera module is packaged by relying on the packaging structure 210.

[0016] The polarizer 300 is provided with a fracture 301, and the polarizer 300 is divided into a first polarizer 310 and a second polarizer 320 through the fracture 301. The first polarizer 310 is provided with a second opening 300a, and the first opening 200a is opposite to and connected with the second opening 300a. The second polarizer 320 is located at the periphery of the first polarizer 310, so the area of ​​the second polarizer 320 is larger, and the area of ​​the first polarizer 310 is smaller. Moreover, in the thickness direction of the display module, the first polarizer 310 is opposite to the packaging structure 210, so the tensile force borne by the first polarizer 310 can be transmitted to the packaging structure 210, and by reducing the tensile force borne by the first polarizer 310, it is helpful to prevent the packaging structure 210 from being damaged.

[0017] In the embodiment of the present application, the first polarizing portion 310 and the second polarizing portion 320 are separated by the fracture 301. When the polarizer 300 is stretched, at least part of the stretching force borne by the second polarizing portion 320 will not be transmitted to the first polarizing portion 310, so that the stretching force borne by the first polarizing portion 310 is reduced. Since the first opening 200a is opposite to the second opening 300a, the first polarizing portion 310 with the second opening 300a is opposite to the packaging structure 210 with the first opening 200a, so the shear force applied by the first polarizing portion 310 to the packaging structure 210 is also reduced, the packaging structure 210 is not easily damaged, and the elements such as iodine and potassium in the polarizer 300 are not easily penetrated into the packaging structure 210, thereby avoiding packaging failure, and further preventing the display panel 200 from being corroded by water and oxygen, thereby improving the reliability of the display module under high temperature and high humidity conditions and reducing the risk of black spots and flowery screens.

[0018] In an optional embodiment, the polarizer 300 may be cut by laser cutting to form a fracture 301. The structure of the polarizer 300 before being subjected to the tensile force is shown in FIG. Figure 1 and Figure 3 As shown, when the polarizer 300 is subjected to a tensile force, the second polarizer 320 is stretched, and the tensile force borne by the first polarizer 310 is small or even zero, so that the fracture 301 between the first polarizer 310 and the second polarizer 320 becomes larger and larger. Figure 2 and Figure 4 Of course, the polarizer 300 may also be provided with the fracture 301 by other methods other than laser cutting.

[0019] In an alternative embodiment, reference Figure 1 and Figure 2 As shown, the portion of the display panel 200 corresponding to the non-display area also includes a non-encapsulation structure 220, which is located at the periphery of the encapsulation structure 210. Along the thickness direction of the display module, the projection of the fracture 301 is located within the projection of the non-encapsulation structure 220, and only a portion of the projection of the first polarizer 310 coincides with the projection of the encapsulation structure 210. In other words, in the thickness direction of the display module, the fracture 301 is opposite to the non-encapsulation structure 220. Then, only a portion of the first polarizer 310 corresponds to the encapsulation structure 210, and when the polarizer 300 is subjected to a tensile force, only the first polarizer 310 applies a shear force to the encapsulation structure 210.

[0020] With this embodiment, the fracture 301 is relatively far away from the packaging structure 210, so the packaging structure 210 is only affected by the first polarizing unit 310, avoiding the tensile force borne by the second polarizing unit 320 from affecting the packaging structure 210, which is beneficial to reducing the shear force applied by the polarizer 300 to the packaging structure 210. The packaging structure 210 is less likely to be damaged, and elements such as iodine and potassium in the polarizer 300 are less likely to penetrate into the packaging structure 210, effectively avoiding packaging failure, further preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0021] Of course, in other embodiments, along the thickness direction of the display module, the projection of the fracture 301 may be located within the projection of the encapsulation structure 210, and a portion of the projection of the first polarizing unit 310 and the projection of the second polarizing unit 320 are located within the projection of the encapsulation structure 210. In other words, in the thickness direction of the display module, the fracture 301 is opposite to the encapsulation structure 210, and then a portion of the first polarizing unit 310 and the second polarizing unit 320 correspond to the encapsulation structure 210, respectively. When the polarizer 300 is subjected to a tensile force, both the first polarizing unit 310 and the second polarizing unit 320 can exert a shear force on the encapsulation structure 210.

[0022] In an optional embodiment, reference Figure 3 and Figure 4 As shown, along the thickness direction of the display module, the projection of the break 301 is a closed structure, so that the second polarizer 320 surrounds the entire arrangement of the first polarizer 310, and the first polarizer 310 and the second polarizer 320 are separated by the break 301. Optionally, along the thickness direction of the display module, the projection of the break 301 can be a circular ring structure or a square ring structure. Of course, the projection of the break 301 can also be a closed structure of other shapes.

[0023] In this embodiment, the fracture 301 separates the first polarizing portion 310 and the second polarizing portion 320. When the polarizer 300 is stretched, the stretching force borne by the second polarizing portion 320 will not be transmitted to the first polarizing portion 310. In other words, the first polarizing portion 310 will not be subjected to the stretching force. Therefore, the first polarizing portion 310 will not apply a shearing force to the packaging structure 210, thereby effectively preventing the packaging structure 210 from being damaged or failing, effectively preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0024] In another embodiment, reference Figure 8The schematic diagram of the projection of the fracture 301 shown in the figure shows that along the thickness direction of the display module, there is at least one first opening 301a in the projection of the fracture 301, that is, the projection of the fracture 301 is a non-closed structure, a part of the first polarizing part 310 is separated from the second polarizing part 320 by the fracture 301, and another part of the first polarizing part 310 is connected to the second polarizing part 320.

[0025] Optionally, along the thickness direction of the display module, the projection of the fracture 301 has a first opening 301a, and the number of fractures 301 is one; or, along the thickness direction of the display module, the projection of the fracture 301 has multiple first openings 301a, in which case the number of fractures 301 is multiple, and a first opening 301a is formed between the projections of two adjacent fractures 301, that is, along the thickness direction of the display module, the projections of the multiple fractures 301 are discontinuously distributed, and the shapes of the projections of the various fractures 301 may be the same or different. Further optionally, along the thickness direction of the display module, the projection of the fracture 301 may be a linear structure, an arc structure, or other structures, and the embodiment of the present application does not limit the specific shape of the fracture 301.

[0026] According to the present embodiment, a part of the first polarizing unit 310 is separated from the second polarizing unit 320 by the fracture 301, and another part of the first polarizing unit 310 is connected to the second polarizing unit 320. Therefore, when the polarizer 300 is stretched, a part of the stretching force borne by the second polarizing unit 320 will not be transmitted to the first polarizing unit 310, the stretching force borne by the first polarizing unit 310 is reduced, and the shearing force applied by the first polarizing unit 310 to the packaging structure 210 is also reduced. The packaging structure 210 is not easily damaged, and the elements such as iodine and potassium in the polarizer 300 are not easily penetrated into the packaging structure 210, thereby avoiding packaging failure. Moreover, the part where the first polarizing unit 310 and the second polarizing unit 320 are connected is conducive to the polarizer 300 forming an integral structure, and is conducive to the first polarizing unit 310 and the second polarizing unit 320 being in the same installation plane, thereby helping to reduce the difficulty of installation and the difficulty of process of the polarizer 300.

[0027] In the scheme of this application, reference is made to Figure 1 and Figure 2 As shown, the display module also includes a first connecting adhesive layer 400, and the display panel 200 and the polarizer 300 are connected through the first connecting adhesive layer 400, that is, the display panel 200 and the polarizer 300 are bonded, and the first connecting adhesive layer 400 can be but is not limited to hot melt adhesive. The embodiment of the present application does not limit the specific type of the first connecting adhesive layer 400.

[0028] Optionally, the laying area of ​​the first connecting adhesive layer 400 is equal to the laying area of ​​the polarizer 300 or the display panel 200, and the first connecting adhesive layer 400 is provided with a fourth opening 400a, and the fourth opening 400a is respectively opposite to and connected with the first opening 200a and the second opening 300a, so that the fourth opening 400a is opposite to the camera module. That is, in the thickness direction of the display module, the first opening 200a, the fourth opening 400a, and the second opening 300a are opposite in sequence.

[0029] In an alternative embodiment, reference Figure 5 As shown, the first connecting adhesive layer 400 is provided with a first notch 410, and the first notch 410 runs through the first connecting adhesive layer 400. The first notch 410 can be a square opening, a circular opening, etc., and the embodiment of the present application does not limit the specific shape of the first notch 410. The first connecting adhesive layer 400 is divided into a first connecting portion 420 and a second connecting portion 430 through the first notch 410. The portion of the display panel 200 corresponding to the non-display area also includes a non-encapsulation structure 220, and the non-encapsulation structure 220 is located at the periphery of the encapsulation structure 210. The non-encapsulation structure 220 is arranged around the encapsulation structure 210, and the first polarizing portion 310 is connected to the encapsulation structure 210 through the first connecting portion 420, and the second polarizing portion 320 is connected to the non-encapsulation structure 220 through the second connecting portion 430.

[0030] Specifically, at least part of the second polarizer 320 and the second connecting part 430 are opposite to the non-encapsulation structure 220 in sequence, and at least part of the first polarizer 310 and the first connecting part 420 are opposite to the encapsulation structure 210 in sequence. That is to say, along the thickness direction of the display module, at least part of the projection of the first polarizer 310 is located within the projection of the first connecting part 420, and at least part of the projection of the first connecting part 420 is located within the projection of the encapsulation structure 210, at least part of the projection of the second polarizer 320 is located within the projection of the second connecting part 430, and at least part of the projection of the second connecting part 430 is located within the projection of the non-encapsulation structure 220. In this way, when the polarizer 300 is subjected to a tensile force, the first polarizer 310 can apply a shear force to the encapsulation structure 210 through the first connecting part 420, and the second polarizer 320 can apply a shear force to the non-encapsulation structure 220 through the second connecting part 430.

[0031] Since the second polarizing portion 320 is connected to the second connecting portion 430, the second connecting portion 430 is subjected to the shear force applied by the second polarizing portion 320. According to the present embodiment, the first connecting adhesive layer 400 is separated by the first notch 410 to prevent the second connecting portion 430 from applying a shear force to the packaging structure 210 through the first connecting portion 420, which is beneficial to further reduce the shear force borne by the packaging structure 210, and the packaging structure 210 is less likely to be damaged. The elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the packaging structure 210, which effectively avoids packaging failure, further prevents the display panel 200 from being corroded by water and oxygen, and avoids problems such as black spots and flowery screens.

[0032] Of course, in other embodiments, the first connection adhesive layer 400 may not be provided with the first notch 410 , that is, the first connection portion 420 and the second connection portion 430 are an integrated structure.

[0033] In an optional embodiment, along the thickness direction of the display module, the projection of the first notch 410 is a closed structure, so that the second connection part 430 surrounds the entire arrangement of the first connection part 420, and the first connection part 420 and the second connection part 430 are separated by the first notch 410. Optionally, along the thickness direction of the display module, the projection of the first notch 410 may be a circular ring structure, the projection of the first notch 410 may also be a square ring structure, and of course, the projection of the first notch 410 may also be a closed structure of other shapes.

[0034] With this embodiment, the first notch 410 separates the first connection part 420 and the second connection part 430, preventing the second connection part 430 from applying a shear force to the packaging structure 210 through the first connection part 420, which is beneficial to further reduce the shear force on the packaging structure 210, and the packaging structure 210 is less likely to be damaged. The iodine, potassium and other elements in the polarizer 300 are also less likely to penetrate into the packaging structure 210, effectively avoiding packaging failure, further preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0035] In another embodiment, reference Fig. 9 The schematic diagram of the projection of the first notch 410 shown in the figure shows that, along the thickness direction of the display module, there is at least one second opening 411 in the projection of the first notch 410, that is, the projection of the first notch 410 is a non-closed structure, a part of the first connecting part 420 is separated from the second connecting part 430 by the first notch 410, and another part of the first connecting part 420 is connected to the second connecting part 430.

[0036] Optionally, along the thickness direction of the display module, the projection of the first notch 410 has a second opening 411, and the number of the first notch 410 is one; or, along the thickness direction of the display module, the projection of the first notch 410 has multiple second openings 411, in which case the number of the first notches 410 is multiple, and a second opening 411 is formed between the projections of two adjacent first notches 410, that is, along the thickness direction of the display module, the projections of the multiple first notches 410 are discontinuously distributed, and the shapes of the projections of the various first notches 410 may be the same or different. Further optionally, along the thickness direction of the display module, the projection of the first notch 410 may be a linear structure, an arc structure or other structures, and the embodiment of the present application does not limit the specific shape of the first notch 410.

[0037] In this embodiment, a part of the first connection part 420 is separated from the second connection part 430 by the first notch 410, and the other part of the first connection part 420 is connected to the second connection part 430. Therefore, when the polarizer 300 is stretched, a part of the shear force borne by the second connection part 430 will not be transmitted to the first connection part 420, the shear force borne by the first connection part 420 is reduced, and the shear force applied by the first connection part 420 to the packaging structure 210 is also reduced. The packaging structure 210 is not easily damaged, and the elements such as iodine and potassium in the polarizer 300 are not easy to penetrate into the packaging structure 210, thereby avoiding packaging failure; moreover, the part where the first connection part 420 and the second connection part 430 are connected is conducive to the first connection adhesive layer 400 forming an integral structure, which is conducive to the first connection part 420 and the second connection part 430 being located in the same plane, and further conducive to setting the first connection adhesive layer 400 between the display panel 200 and the polarizer 300, thereby reducing the difficulty of installing the display module.

[0038] In an alternative embodiment, reference Figure 5 and Figure 6 As shown, along the thickness direction of the display module, the projection of the first notch 410 is located within the projection of the non-encapsulation structure 220, and only a portion of the projection of the first connection portion 420 coincides with the projection of the encapsulation structure 210. In other words, in the thickness direction of the display module, the first notch 410 is opposite to the non-encapsulation structure 220. Then, only a portion of the first connection portion 420 corresponds to the encapsulation structure 210, and when the polarizer 300 is subjected to tension, only the first connection portion 420 applies a shear force to the encapsulation structure 210.

[0039] In this embodiment, the first notch 410 is relatively far away from the packaging structure 210, so the packaging structure 210 is only affected by the first connecting portion 420, avoiding the shear force borne by the second connecting portion 430 to affect the packaging structure 210, which is beneficial to reducing the shear force applied by the polarizer 300 to the packaging structure 210 through the first connecting adhesive layer 400. The packaging structure 210 is less likely to be damaged, and elements such as iodine and potassium in the polarizer 300 are less likely to penetrate into the packaging structure 210, effectively avoiding packaging failure, further preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0040] Of course, in other embodiments, along the thickness direction of the display module, the projection of the first notch 410 is located within the projection of the packaging structure 210. That is, in the thickness direction of the display module, the first notch 410 is opposite to the packaging structure 210, and then, a portion of the first connection portion 420 and the second connection portion 430 respectively correspond to the packaging structure 210, and when the polarizer 300 is subjected to a tensile force, both the first connection portion 420 and the second connection portion 430 can apply a shear force to the packaging structure 210.

[0041] In an alternative embodiment, reference Figure 6 As shown, along the thickness direction of the display module, at least a portion of the projection of the first notch 410 overlaps with at least a portion of the projection of the fracture 301, that is, in the thickness direction of the display module, the first notch 410 is opposite to the fracture 301, so that the first polarizing portion 310 is opposite to the first connecting portion 420, and the second polarizing portion 320 is opposite to the second connecting portion 430.

[0042] Optionally, the width of the first notch 410 is greater than the width of the fracture 301, and along the thickness direction of the display module, the projection of the fracture 301 is located within the projection of the first notch 410, and along the first direction A, the first notch 410 has a first edge 410a and a second edge 410b, the first edge 410a is located on a side of the fracture 301 away from the first polarizing portion 310, and the second edge 410b is located on a side of the fracture 301 away from the second polarizing portion 320, the first direction A is parallel to the direction of the display panel 200, and the first direction A is parallel to the first direction A. The axis of the first opening 200a is perpendicular; or, the width of the first notch 410 is smaller than the width of the fracture 301, and the projection of the first notch 410 is located within the projection of the fracture 301 along the thickness direction of the display module; or, the width of the first notch 410 is equal to the width of the fracture 301, and the projection of the first notch 410 coincides with the projection of the fracture 301 along the thickness direction of the display module, at which time the first edge 410a and the second edge 410b of the first notch 410 are respectively aligned with the two edges of the fracture 301 along the first direction A.

[0043] In this embodiment, a first notch 410 is set at a position opposite to the fracture 301, and the second polarizing portion 320 applies a shear force to the display panel 200 only through the second connecting portion 430, thereby preventing the second polarizing portion 320 from applying a shear force to the display panel 200 through the first connecting portion 420, which is beneficial to further reduce the shear force borne by the packaging structure 210, and the packaging structure 210 is less likely to be damaged. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the packaging structure 210, effectively avoiding packaging failure, further preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0044] Of course, in other embodiments, along the thickness direction of the display module, the projection of the first notch 410 is located outside the projection of the fracture 301. That is, in the thickness direction of the display module, the first notch 410 and the fracture 301 are staggered. Figure 5 As shown, the first notch 410 is opposite to the second polarizing portion 320, and the projection of the first notch 410 is located within the projection of the second polarizing portion 320 along the thickness direction of the display module; or, the first notch 410 is opposite to the first polarizing portion 310, and the projection of the first notch 410 is located within the projection of the first polarizing portion 310 along the thickness direction of the display module.

[0045] In the scheme of this application, reference is made to Figure 1-Figure 2 as well as Figure 5-Figure 6 As shown, the display module further includes a substrate 100, the material of the substrate 100 may be polyimide, the substrate 100 is located on the side of the display panel 200 facing away from the polarizer 300, the substrate 100 is stacked with the display panel 200, the substrate 100 is used to support the display panel 200, and the encapsulation structure 210 and the non-encapsulation structure 220 are respectively opposite to the substrate 100. In this way, the display panel 200 is supported by the substrate 100, and the display panel 200 and the polarizer 300 are stacked based on the substrate 100.

[0046] refer to Figure 7 As shown, the substrate 100 is provided with a second notch 110, and the substrate 100 is divided into a first substrate portion 120 and a second substrate portion 130 through the second notch 110. The first substrate portion 120 is provided with a third opening 100a, and the third opening 100a is opposite to and connected to the first opening 200a, so that the third opening 100a is opposite to the camera module. In this way, light enters the camera module through the second opening 300a, the first opening 200a and the third opening 100a in sequence, and the camera module realizes the camera function.

[0047] The portion of the display panel 200 corresponding to the non-display area also includes a non-encapsulation structure 220, which is located at the periphery of the encapsulation structure 210. In the thickness direction of the display module, the first substrate portion 120 is opposite to the encapsulation structure 210, and the second substrate portion 130 is opposite to the non-encapsulation structure 220. The first substrate portion 120 is connected to the encapsulation structure 210, and the second substrate portion 130 is connected to the non-encapsulation structure 220. Therefore, the shear force borne by the first substrate portion 120 can be transmitted to the encapsulation structure 210. By reducing the shear force borne by the first substrate portion 120, it is helpful to prevent damage to the encapsulation structure 210.

[0048] Optionally, along the thickness direction of the display module, the projection of the second notch 110 may be a non-enclosed structure, specifically a linear structure or an arc-shaped structure, that is, a portion of the first substrate portion 120 is separated from the second substrate portion 130 through the second notch 110, and another portion of the first substrate portion 120 is connected to the second substrate portion 130. Of course, along the thickness direction of the display module, the projection of the second notch 110 may also be other structures.

[0049] With this embodiment, when the polarizer 300 is stretched, the stretching force borne by the second polarizer 320 will apply a shearing force to the non-encapsulated structure 220, and the substrate 100 will share part of the shearing force borne by the non-encapsulated structure 220, thereby preventing the non-encapsulated structure 220 from applying a large shearing force to the encapsulated structure 210. Moreover, the substrate 100 is divided into two parts by the second notch 110, thereby preventing the shearing force borne by the second substrate part 130 from being applied to the encapsulated structure 210 through the first substrate part 120, which is conducive to further reducing the shearing force borne by the encapsulated structure 210, making the encapsulated structure 210 less likely to be damaged, and elements such as iodine and potassium in the polarizer are less likely to penetrate into the encapsulated structure 210, thereby preventing encapsulation failure, thereby preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0050] Of course, in other embodiments, the display panel 200 may not be provided with the second notch 110 .

[0051] In a further embodiment, along the thickness direction of the display module, the projection of the second notch 110 is located within the projection of the non-encapsulation structure 220. That is, in the thickness direction of the display module, the second notch 110 is opposite to the non-encapsulation structure 220. Specifically, in the thickness direction of the display module, only a portion of the first substrate portion 120 overlaps with the projection of the encapsulation structure 210, and then only a portion of the first substrate portion 120 corresponds to the encapsulation structure 210. With this embodiment, the second notch 110 is relatively far away from the packaging structure 210, so the packaging structure 210 is not affected by the second substrate portion 130, thereby preventing the shear force borne by the second substrate portion 130 from affecting the packaging structure 210, which is beneficial to reducing the shear force borne by the packaging structure 210. The packaging structure 210 is not easily damaged, and elements such as iodine and potassium in the polarizer 300 are less likely to penetrate into the packaging structure 210, effectively avoiding packaging failure, further preventing the display panel 200 from being corroded by water and oxygen, and avoiding problems such as black spots and flowery screens.

[0052] Of course, in other embodiments, along the thickness direction of the display module, the projection of the second notch 110 is located within the projection of the packaging structure 210 .

[0053] In an optional embodiment, the display module also includes a cover plate 600 and a second connecting adhesive layer 500. The cover plate 600 may be a glass plate or a flexible plate. The cover plate 600 is located on the side of the polarizer 300 facing away from the display panel 200. The cover plate 600 is overlapped with the polarizer 300, and the cover plate 600 is connected to the polarizer 300 through the second connecting adhesive layer 500. The second connecting adhesive layer 500 is provided with a fifth opening 500a, and the fifth opening 500a is opposite to and connected to the second opening 300a, so that the fifth opening 500a is opposite to the camera module.

[0054] Thus, the substrate 100, the display panel 200, the polarizer 300 and the cover plate 600 are stacked in sequence. Light enters the camera module through the cover plate 600, the fifth opening 500a, the second opening 300a, the fourth opening 400a, the first opening 200a and the third opening 100a in sequence.

Optionally, a battery module, a circuit board and other functional components are arranged in the device housing, the device housing may include a frame, the display module is arranged in the frame, and the display module can be fixedly connected to the frame by welding, bonding, etc.

[0056] According to the present embodiment, the display module of the electronic device separates the polarizer 300 into a first polarizer portion 310 and a second polarizer portion 320 by setting a fracture 301 on the polarizer 300. At least part of the tensile force borne by the second polarizer 320 will not be transmitted to the first polarizer 310, so that the tensile force borne by the first polarizer 310 is reduced, and the shear force applied by the first polarizer 310 to the packaging structure 210 is also reduced. The packaging structure 210 is not easily damaged, and elements such as iodine and potassium in the polarizer 300 are not easy to penetrate into the packaging structure 210, thereby avoiding packaging failure, thereby preventing the display panel 200 from being corroded by water and oxygen, avoiding problems such as black spots and flowery screens, and ensuring the display function of the display module and the normal use of the electronic device.
