Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a display module and an electronic device. Background Technology

[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. Increasing the screen ratio is an important development direction for 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 screen distortion.

[0003] In related technologies, display modules typically include stacked display panels and polarizers. Both the display panel and polarizer have openings opposite to the camera module. Furthermore, the display panel has a packaging structure that encapsulates the camera module. During high-temperature and high-humidity testing, the polarizer is prone to shrinkage, necessitating subsequent stretching. The polarizer then bears the tensile force. Simultaneously, because the polarizer is connected to the display panel, the tensile force exerted by the polarizer creates a shearing force on the display panel. This shearing force can easily damage the packaging structure, and elements such as iodine and potassium from the polarizer may penetrate into the damaged packaging structure, leading to packaging failure. This results in water and oxygen corrosion of the display panel, causing problems such as black spots and screen distortion. Summary of the Invention

[0004] The purpose of this application is to provide a display module and electronic device that can solve the problem of easy packaging failure of the display panel packaging structure in related technologies.

[0005] In a first aspect, embodiments of this application provide a display module, the display module having a non-display area, the display module including a stacked display panel and a polarizer, the portion of the display panel corresponding to the non-display area including an encapsulation structure, the encapsulation structure having a first opening.

[0006] The polarizer has a break, and the polarizer is divided into a first polarizing part and a second polarizing part through the break. The first polarizing part has a second opening, and the first opening is opposite to the second opening. The second polarizing part is located on the periphery of the first polarizing part.

[0007] Secondly, embodiments of this application also provide an electronic device, including a device housing and the aforementioned display module, wherein the display module is disposed on the device housing.

[0008] In this embodiment, the first polarizing part and the second polarizing part are separated by a break. When the polarizer is stretched, at least part of the tensile force borne by the second polarizing part will not be transmitted to the first polarizing part, thereby reducing the tensile force borne by the first polarizing part. Since the first opening and the second opening are opposite to each other, the first polarizing part with the second opening is opposite to the encapsulation structure with the first opening. Therefore, the shear force exerted by the first polarizing part on the encapsulation structure is also reduced, and the encapsulation structure is not easily damaged. Elements such as iodine and potassium in the polarizer are also not easily penetrated into the encapsulation structure, thus avoiding encapsulation failure and preventing the display panel from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The display module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] Please refer to Figures 1-9 The display module disclosed in this application is applied to an electronic device, and the display module performs a display function. The display module has a non-display area, which is located at the edge of the display module and is used for encapsulation. The display module also has a display area, and the non-display area is arranged around the display area.

[0030] refer to Figure 1 and Figure 2As shown, the display module includes a stacked display panel 200 and a polarizer 300. The display panel 200 is used for display functions, and the polarizer 300 is used for light filtering. The polarizer 300 separates the incident light, allowing some light to pass through while the rest is absorbed, reflected, and scattered to achieve concealment. The display panel 200 and the polarizer 300 are respectively provided with a first opening 200a and a second opening 300a, which are opposite to each other. The first opening 200a and the second opening 300a are respectively opposite to the camera module. Light enters the camera module through the first opening 200a and the second opening 300a, enabling the camera module to perform the camera function. The first opening 200a and the second opening 300a can be circular holes, square holes, or other structures, and the first opening 200a and the second opening 300a have the same shape and size. In this way, the camera module can be encapsulated in the non-display area, and both the first opening 200a and the second opening 300a are located in the non-display area, so as to avoid the first opening 200a and the second opening 300a affecting the display effect of the display area.

[0031] The portion of the display panel 200 corresponding to the non-display area includes an encapsulation structure 210, which has a first opening 200a. Optionally, the encapsulation structure 210 can be an annular structure with the first opening 200a being a circular hole; alternatively, the encapsulation structure 210 can be a square annular structure with the first opening 200a being a square hole, with the encapsulation structure 210 surrounding the first opening 200a. This embodiment does not limit the shape of the encapsulation structure 210 and the first opening 200a. Thus, the camera module is encapsulated using the encapsulation structure 210.

[0032] The polarizer 300 has a break 301, dividing it into a first polarizing portion 310 and a second polarizing portion 320. The first polarizing portion 310 has a second opening 300a, which is opposite to and communicates with the first opening 200a. The second polarizing portion 320 is located on the periphery of the first polarizing portion 310, thus the area of ​​the second polarizing portion 320 is larger than that of the first polarizing portion 310. Furthermore, in the thickness direction of the display module, the first polarizing portion 310 is opposite to the encapsulation structure 210, so the tensile force borne by the first polarizing portion 310 can be transmitted to the encapsulation structure 210. By reducing the tensile force borne by the first polarizing portion 310, it helps to prevent damage to the encapsulation structure 210.

[0033] In this embodiment, the first polarizing part 310 and the second polarizing part 320 are separated by the break 301. When the polarizer 300 is stretched, at least part of the tensile force borne by the second polarizing part 320 will not be transmitted to the first polarizing part 310, thereby reducing the tensile force borne by the first polarizing part 310. Since the first opening 200a is opposite to the second opening 300a, and the first polarizing part 310 with the second opening 300a is opposite to the encapsulation structure 210 with the first opening 200a, the shear force exerted by the first polarizing part 310 on the encapsulation structure 210 is also reduced. The encapsulation structure 210 is not easily damaged, and elements such as iodine and potassium in the polarizer 300 are not easily penetrated into the encapsulation structure 210, thus avoiding encapsulation failure. This prevents the display panel 200 from being corroded by water and oxygen, improves the reliability of the display module under high temperature and high humidity conditions, and reduces the risk of black spots and screen distortion.

[0034] In an optional embodiment, a fracture 301 can be created in the polarizer 300 using laser cutting technology. This is a structural reference image of the polarizer 300 before it is subjected to tensile force. Figure 1 and Figure 3 As shown, when the polarizer 300 is subjected to tensile force, the second polarizing portion 320 is stretched, while the first polarizing portion 310 experiences a smaller or even zero tensile force. This causes the fracture 301 between the first polarizing portion 310 and the second polarizing portion 320 to become increasingly larger. (Refer to...) Figure 2 and Figure 4 As shown. Of course, the polarizer 300 can also be cut with a break 301 by means other than laser cutting.

[0035] In an optional embodiment, refer to Figure 1 and Figure 2 As shown, the portion of the display panel 200 corresponding to the non-display area also includes a non-encapsulated structure 220. The non-encapsulated structure 220 is located around the encapsulated structure 210. Along the thickness direction of the display module, the projection of the break 301 lies within the projection of the non-encapsulated structure 220, with only a portion of the projection of the first polarizing portion 310 coinciding with the projection of the encapsulated structure 210. That is, in the thickness direction of the display module, the break 301 is opposite to the non-encapsulated structure 220. Therefore, only a portion of the first polarizing portion 310 corresponds to the encapsulated structure 210. When the polarizer 300 is subjected to tensile force, only the first polarizing portion 310 applies shear force to the encapsulated structure 210.

[0036] In this embodiment, the break 301 is relatively far from the encapsulation structure 210. Therefore, the encapsulation structure 210 is only affected by the first polarizing part 310, avoiding the tensile force borne by the second polarizing part 320 from affecting the encapsulation structure 210. This helps to reduce the shear force exerted by the polarizer 300 on the encapsulation structure 210, making the encapsulation structure 210 less prone to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, effectively avoiding encapsulation failure and further preventing the display panel 200 from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

[0037] Of course, in other embodiments, along the thickness direction of the display module, the projection of the break 301 can be located within the projection of the encapsulation structure 210, and a portion of the projections of the first polarizing portion 310 and the second polarizing portion 320 are located within the projection of the encapsulation structure 210. That is, in the thickness direction of the display module, the break 301 is opposite to the encapsulation structure 210, then a portion of the first polarizing portion 310 and the second polarizing portion 320 respectively correspond to the encapsulation structure 210. When the polarizer 300 is subjected to tensile force, both the first polarizing portion 310 and the second polarizing portion 320 can apply shear force to the encapsulation structure 210.

[0038] In one alternative embodiment, reference is made to... 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, causing the second polarizing part 320 to be arranged around the entire first polarizing part 310, and the first polarizing part 310 and the second polarizing part 320 to be 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.

[0039] In this embodiment, the break 301 separates the first polarizing part 310 and the second polarizing part 320. When the polarizer 300 is stretched, the tensile force borne by the second polarizing part 320 will not be transmitted to the first polarizing part 310. In other words, the first polarizing part 310 will not bear the tensile force. Therefore, the first polarizing part 310 will not apply shear force to the encapsulation structure 210, effectively preventing the encapsulation 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 screen distortion.

[0040] In another embodiment, reference Figure 8The schematic diagram of the projection of the fracture 301 shown shows that, along the thickness direction of the display module, the projection of the fracture 301 has at least one first opening 301a, 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 through the fracture 301, and the other part of the first polarizing part 310 is connected to the second polarizing part 320.

[0041] Optionally, along the thickness direction of the display module, the projection of the fracture 301 has one 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 multiple fractures 301 are discontinuously distributed, and the shapes of the projections of each fracture 301 can be the same or different. Further optionally, along the thickness direction of the display module, the projection of the fracture 301 can be a straight line structure, an arc structure, or other structures. The embodiments of this application do not limit the specific shape of the fracture 301.

[0042] In this embodiment, a portion of the first polarizing part 310 is separated from the second polarizing part 320 through the break 301, while the other portion of the first polarizing part 310 is connected to the second polarizing part 320. Therefore, when the polarizer 300 is stretched, a portion of the tensile force borne by the second polarizing part 320 will not be transmitted to the first polarizing part 310. The tensile force borne by the first polarizing part 310 is reduced, and the shear force exerted by the first polarizing part 310 on the packaging structure 210 is also reduced. 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, thus avoiding packaging failure. Moreover, the connection between the first polarizing part 310 and the second polarizing part 320 is beneficial for the polarizer 300 to form an integral structure, and for the first polarizing part 310 and the second polarizing part 320 to be on the same mounting plane, thereby reducing the installation difficulty and manufacturing difficulty of the polarizer 300.

[0043] 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. 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 together. The first connecting adhesive layer 400 can be, but is not limited to, hot melt adhesive. The embodiments of this application do not limit the specific type of the first connecting adhesive layer 400.

[0044] Optionally, the area of ​​the first adhesive layer 400 is equal to the area of ​​the polarizer 300 or the display panel 200. The first adhesive layer 400 is provided with a fourth opening 400a, which is opposite to and connected to the first opening 200a and the second opening 300a, respectively, 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 sequentially opposite each other.

[0045] In an optional embodiment, refer to Figure 5 As shown, the first connecting adhesive layer 400 has a first notch 410, which penetrates the first connecting adhesive layer 400. The first notch 410 can be square, circular, etc., and the specific shape of the first notch 410 is not limited in this embodiment. 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-encapsulated structure 220, which is located around the encapsulated structure 210. The non-encapsulated structure 220 is arranged around the encapsulated structure 210. The first polarizing portion 310 is connected to the encapsulated structure 210 through the first connecting portion 420, and the second polarizing portion 320 is connected to the non-encapsulated structure 220 through the second connecting portion 430.

[0046] Specifically, at least portions of the second polarizing portion 320 and the second connecting portion 430 are sequentially opposite to the unencapsulated structure 220, and at least portions of the first polarizing portion 310 and the first connecting portion 420 are sequentially opposite to the encapsulated structure 210. That is, along the thickness direction of the display module, at least a portion of the projection of the first polarizing portion 310 lies within the projection of the first connecting portion 420, and at least a portion of the projection of the first connecting portion 420 lies within the projection of the encapsulated structure 210; at least a portion of the projection of the second polarizing portion 320 lies within the projection of the second connecting portion 430, and at least a portion of the projection of the second connecting portion 430 lies within the projection of the unencapsulated structure 220. Thus, when the polarizer 300 is subjected to tensile force, the first polarizing portion 310 can apply a shearing force to the encapsulated structure 210 through the first connecting portion 420, and the second polarizing portion 320 can apply a shearing force to the unencapsulated structure 220 through the second connecting portion 430.

[0047] Since the second polarizing part 320 is connected to the second connecting part 430, and the second connecting part 430 bears the shear force applied by the second polarizing part 320, in this embodiment, the first connecting adhesive layer 400 is separated by the first notch 410, which prevents the second connecting part 430 from applying shear force to the encapsulation structure 210 through the first connecting part 420. This helps to further reduce the shear force borne by the encapsulation structure 210, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, effectively preventing encapsulation failure and further preventing the display panel 200 from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

[0048] Of course, in other embodiments, the first connecting adhesive layer 400 may not have the first notch 410, that is, the first connecting part 420 and the second connecting part 430 are an integral structure.

[0049] In one optional embodiment, the projection of the first notch 410 along the thickness direction of the display module is a closed structure, such that the second connecting portion 430 is disposed around the entire first connecting portion 420, and the first connecting portion 420 and the second connecting portion 430 are separated by the first notch 410. Optionally, the projection of the first notch 410 along the thickness direction of the display module can be a circular ring structure, or it can be a square ring structure. Of course, the projection of the first notch 410 can also be a closed structure of other shapes.

[0050] In this embodiment, the first notch 410 separates the first connecting portion 420 and the second connecting portion 430, preventing the second connecting portion 430 from applying shear force to the encapsulation structure 210 through the first connecting portion 420. This helps to further reduce the shear force borne by the encapsulation structure 210, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, effectively preventing encapsulation failure and further preventing the display panel 200 from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

[0051] In another embodiment, reference Figure 9 The projection diagram of the first notch 410 shown shows that, along the thickness direction of the display module, the projection of the first notch 410 has at least one second opening 411, 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 through the first notch 410, and the other part of the first connecting part 420 is connected to the second connecting part 430.

[0052] 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 first notches 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 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 multiple first notches 410 are discontinuously distributed, and the shapes of the projections of each first notch 410 can be the same or different. Further optionally, along the thickness direction of the display module, the projection of the first notch 410 can be a straight line structure, an arc structure, or other structures. The embodiments of this application do not limit the specific shape of the first notch 410.

[0053] In this embodiment, a portion of the first connecting part 420 is separated from the second connecting part 430 through the first notch 410, while the other portion of the first connecting part 420 is connected to the second connecting part 430. Therefore, when the polarizer 300 is stretched, a portion of the shear force borne by the second connecting part 430 will not be transmitted to the first connecting part 420, reducing the shear force borne by the first connecting part 420. Consequently, the shear force exerted by the first connecting part 420 on the encapsulation structure 210 is also reduced, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, thus preventing encapsulation failure. Furthermore, the connection between the first connecting part 420 and the second connecting part 430 facilitates the formation of an integral structure of the first connecting adhesive layer 400, which in turn facilitates the first connecting part 420 and the second connecting part 430 being located on the same plane. This, in turn, facilitates the placement of the first connecting adhesive layer 400 between the display panel 200 and the polarizer 300, reducing the installation difficulty of the display module.

[0054] In an optional embodiment, refer to Figure 5 and Figure 6 As shown, along the thickness direction of the display module, the projection of the first notch 410 lies within the projection of the non-encapsulated structure 220, with only a portion of the projection of the first connecting portion 420 coinciding with the projection of the encapsulated structure 210. In other words, along the thickness direction of the display module, the first notch 410 is opposite to the non-encapsulated structure 220. Therefore, only a portion of the first connecting portion 420 corresponds to the encapsulated structure 210, and when the polarizer 300 is subjected to tensile forces, only the first connecting portion 420 applies a shearing force to the encapsulated structure 210.

[0055] In this embodiment, the first notch 410 is relatively far from the encapsulation structure 210. Therefore, the encapsulation structure 210 is only affected by the first connecting part 420, avoiding the shear force borne by the second connecting part 430 from affecting the encapsulation structure 210. This helps to reduce the shear force exerted by the polarizer 300 on the encapsulation structure 210 through the first connecting adhesive layer 400, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, effectively preventing encapsulation failure and further preventing the display panel 200 from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

[0056] Of course, in other embodiments, the projection of the first notch 410 is located within the projection of the encapsulation structure 210 along the thickness direction of the display module. That is, in the thickness direction of the display module, the first notch 410 is opposite to the encapsulation structure 210. Then, a portion of the first connecting portion 420 and a portion of the second connecting portion 430 respectively correspond to the encapsulation structure 210. When the polarizer 300 is subjected to tensile force, both the first connecting portion 420 and the second connecting portion 430 can apply shear force to the encapsulation structure 210.

[0057] In an optional embodiment, refer to Figure 6 As shown, along the thickness direction of the display module, at least a portion of the projection of the first notch 410 coincides with at least a portion of the projection of the break 301. That is, in the thickness direction of the display module, the first notch 410 is opposite to the break 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.

[0058] Optionally, the width of the first notch 410 is greater than the width of the break 301. Along the thickness direction of the display module, the projection of the break 301 is located within the projection of the first notch 410. 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 the side of the break 301 away from the first polarizing portion 310, and the second edge 410b is located on the side of the break 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 direction of the first polarizing portion 320. The axis of the opening 200a is perpendicular to the opening; or, the width of the first notch 410 is less 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. In this case, 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.

[0059] In this embodiment, a first notch 410 is provided at a position opposite to the break 301. The second polarizing part 320 applies shear force to the display panel 200 only through the second connecting part 430, avoiding the second polarizing part 320 applying shear force to the display panel 200 through the first connecting part 420. This helps to further reduce the shear force borne by the encapsulation structure 210, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, effectively preventing encapsulation failure and further preventing the display panel 200 from being corroded by water and oxygen, thus avoiding problems such as black spots and screen distortion.

[0060] Of course, in other embodiments, the projection of the first notch 410 is located outside the projection of the fracture 301 along the thickness direction of the display module. That is, the first notch 410 and the fracture 301 are misaligned along the thickness direction of the display module. Specifically, refer to... Figure 5 As shown, the first notch 410 is opposite to the second polarizing part 320, and the projection of the first notch 410 is located within the projection of the second polarizing part 320 along the thickness direction of the display module; or, the first notch 410 is opposite to the first polarizing part 310, and the projection of the first notch 410 is located within the projection of the first polarizing part 310 along the thickness direction of the display module.

[0061] In the scheme of this application, reference is made to Figure 1-Figure 2 as well as Figures 5-6 As shown, the display module also includes a substrate 100, which can be made of 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 and is used to support the display panel 200. 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.

[0062] refer to Figure 7 As shown, the substrate 100 has a second notch 110, which divides the substrate 100 into a first substrate portion 120 and a second substrate portion 130. The first substrate portion 120 has a third opening 100a, which is opposite to and communicates with the first opening 200a, so that the third opening 100a is opposite to the camera module. In this way, light enters the camera module sequentially through the second opening 300a, the first opening 200a, and the third opening 100a, and the camera module realizes the camera function.

[0063] The portion of the display panel 200 corresponding to the non-display area also includes a non-encapsulated structure 220. The non-encapsulated structure 220 is located around the encapsulated structure 210. In the thickness direction of the display module, the first substrate portion 120 is opposite to the encapsulated structure 210, and the second substrate portion 130 is opposite to the non-encapsulated structure 220. The first substrate portion 120 is connected to the encapsulated structure 210, and the second substrate portion 130 is connected to the non-encapsulated structure 220. Therefore, the shear force borne by the first substrate portion 120 can be transmitted to the encapsulated structure 210. By reducing the shear force borne by the first substrate portion 120, it is helpful to prevent damage to the encapsulated structure 210.

[0064] Optionally, along the thickness direction of the display module, the projection of the second notch 110 can be a non-closed 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, while the other 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 can also be other structures.

[0065] In this embodiment, when the polarizer 300 is stretched, the tensile force on the second polarizer 320 will exert a shear force on the non-encapsulated structure 220. The substrate 100 shares part of the shear force on the non-encapsulated structure 220, preventing the non-encapsulated structure 220 from exerting a large shear force on the encapsulated structure 210. Moreover, the substrate 100 is divided into two parts by the second notch 110, preventing the shear force on the second substrate part 130 from being applied to the encapsulated structure 210 through the first substrate part 120. This further reduces the shear force on the encapsulated structure 210, making it less susceptible to damage. Elements such as iodine and potassium in the polarizer are also less likely to penetrate into the encapsulated structure 210, preventing encapsulation failure. This, in turn, prevents the display panel 200 from being corroded by water and oxygen, avoiding problems such as black spots and screen distortion.

[0066] Of course, in other embodiments, the display panel 200 may not have the second notch 110.

[0067] In a further embodiment, the projection of the second notch 110 lies within the projection of the non-encapsulated structure 220 along the thickness direction of the display module. That is, the second notch 110 is opposite to the non-encapsulated structure 220 in the thickness direction of the display module. Specifically, in the thickness direction of the display module, only a portion of the first substrate portion 120 coincides with the projection of the encapsulated structure 210, so only a portion of the first substrate portion 120 corresponds to the encapsulated structure 210.

[0068] In this embodiment, the second notch 110 is relatively far from the encapsulation structure 210, so the encapsulation structure 210 is not affected by the second substrate portion 130. This avoids the shear force borne by the second substrate portion 130 affecting the encapsulation structure 210, which helps to reduce the shear force borne by the encapsulation structure 210. The encapsulation structure 210 is not easily damaged, and elements such as iodine and potassium in the polarizer 300 are less likely to penetrate into the encapsulation structure 210, effectively avoiding encapsulation failure. Furthermore, it avoids water and oxygen corrosion of the display panel 200 and avoids problems such as black spots and screen distortion.

[0069] Of course, in other embodiments, the projection of the second notch 110 is located within the projection of the encapsulation structure 210 along the thickness direction of the display module.

[0070] In an optional embodiment, the display module further includes a cover plate 600 and a second connecting adhesive layer 500. The cover plate 600 can 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 stacked with the polarizer 300, and the cover plate 600 and the polarizer 300 are connected by the second connecting adhesive layer 500. The second connecting adhesive layer 500 is provided with a fifth opening 500a. The fifth opening 500a is opposite to and communicates with the second opening 300a, so that the fifth opening 500a is opposite to the camera module.

[0071] Thus, the substrate 100, display panel 200, polarizer 300, and cover plate 600 are stacked in sequence. Light enters the camera module sequentially 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.

[0072] Based on the display module disclosed in this application, this application also discloses an electronic device. The electronic device includes a device housing and the display module described in the above embodiments, with the display module disposed within the device housing. Optionally, the device housing may contain a battery module, a circuit board, and other functional components. The device housing may include a frame, with the display module disposed within the frame. The display module may be fixedly connected to the frame by welding, bonding, or other methods.

[0073] In this embodiment, the display module of the electronic device divides the polarizer 300 into a first polarizing section 310 and a second polarizing section 320 by setting a break 301 in the polarizer 300. At least part of the tensile force borne by the second polarizing section 320 will not be transmitted to the first polarizing section 310, thereby reducing the tensile force borne by the first polarizing section 310. The shear force exerted by the first polarizing section 310 on the encapsulation structure 210 is also reduced, making the encapsulation structure 210 less susceptible to damage. Elements such as iodine and potassium in the polarizer 300 are also less likely to penetrate into the encapsulation structure 210, thus avoiding encapsulation failure. This prevents the display panel 200 from being corroded by water and oxygen, avoids problems such as black spots and screen distortion, ensures the display function of the display module, and ensures the normal use of the electronic device.
