Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to a display module, a display screen, and an electronic device. Background Art

[0002] At present, mobile phones, computers and other electronic devices have become inseparable from our lives. They can be seen everywhere in our lives and have greatly improved people's living standards. With the rapid development of communication equipment technology, the related display industry has also continued to develop, making the application range of display screens increasingly wide.

[0003] In related technologies, a display screen generally includes a display module and a glass cover plate, wherein the glass cover plate is located above the display module. The display module generally includes a substrate layer, a light-emitting layer, an encapsulation layer, and a touch layer, which are stacked in sequence. The encapsulation layer includes an organic encapsulation layer and an inorganic encapsulation layer. The inorganic encapsulation layer is located between the light-emitting layer and the organic encapsulation layer, and the organic encapsulation layer is located between the inorganic encapsulation layer and the touch layer.

[0004] However, in the above solution, when the display screen is bent or subjected to external impact, the display module is prone to cracks or bright spots, which will affect the display effect of the display screen and further affect the visual experience of consumers when using electronic devices. Summary of the Invention

[0005] The embodiments of the present application provide a display module, a display screen, and an electronic device, which can avoid or alleviate problems such as cracks or bright spots that easily occur when the display module is bent or subjected to external impact, thereby improving the display effect of the display screen and further improving the visual experience of consumers when using electronic devices.

[0006] In a first aspect, an embodiment of the present application provides a display module, which is applied to a flexible display screen. The display module includes at least: a stacked display body layer and an encapsulation layer; the encapsulation layer includes: a first inorganic layer, a first organic layer and a second organic layer; the first inorganic layer is located between the display body layer and the first organic layer, and the first organic layer is located between the first inorganic layer and the second organic layer.

[0007] The display module provided in the embodiment of the present application can improve the reliability of the display module by disposing a second organic layer above the first organic layer. The second organic layer uses organic materials. In this way, when the display module is bent or subjected to external impact, problems such as cracks or bright spots in the display module can be avoided or reduced, thereby improving the display effect of the display screen and further enhancing the visual experience of consumers when using electronic devices.

[0008] In one possible implementation of the first aspect, the encapsulation layer further includes a first barrier disposed around the second organic layer. The second organic layer is made of a relatively soft organic material. By disposing the first barrier around the second organic layer, the first barrier encloses the second organic layer within the accommodation space formed by the first barrier. When the display module is bent or subjected to external impact, the second organic layer is prevented from being excessively squeezed, thereby preventing or mitigating severe deformation of the display module.

[0009] In a possible implementation of the first aspect, an outer edge of the first blocking member is flush with an outer edge of the display body layer, thereby ensuring the structural aesthetics of the display module.

[0010] In a possible implementation of the first aspect, the projection area of ​​the second organic layer on the display body layer is smaller than the projection area of ​​the first organic layer on the display body layer; wherein the projection area of ​​the second organic layer on the display body layer is located in the weak area of ​​the display module.

[0011] By setting a second organic layer in the weak area of ​​the display module, and the second organic layer uses organic materials, the reliability of the weak area of ​​the display module can be improved, and then the overall reliability of the display module can be improved. In this way, when the display module is bent or subjected to external impact, problems such as cracks or bright spots in the display module can be avoided or alleviated.

[0012] In one possible implementation of the first aspect, a surface of the second organic layer facing away from the first organic layer is arched. By designing the surface of the second organic layer facing away from the first organic layer (i.e., the surface of the second organic layer facing the front of the display module) to be arched, the structural strength of the display module can be further increased when bent or subjected to external impact, thereby further improving the overall reliability of the display module.

[0013] In a possible implementation manner of the first aspect, the encapsulation layer further includes: a second inorganic layer; the second inorganic layer is located between the first organic layer and the second organic layer.

[0014] By setting a second inorganic layer between the first organic layer and the second organic layer, the first organic layer and the second organic layer use organic materials, which are relatively soft and flexible, and the second inorganic layer uses inorganic materials, which are relatively hard. The second inorganic layer can separate the first organic layer and the second organic layer, and can improve the structural strength of the first organic layer and the second organic layer stacked together, thereby increasing the overall structural strength of the display module.

[0015] In one possible implementation of the first aspect, the encapsulation layer further includes a third inorganic layer; the third inorganic layer is located on a side of the second organic layer facing away from the first organic layer. By covering the side of the second organic layer facing away from the first organic layer with the third inorganic layer, the third inorganic layer can protect the second organic layer, thereby further improving the bending reliability and impact resistance of the display module.

[0016] In a second aspect, an embodiment of the present application provides a display module, which is applied to a flexible display screen, and the display module includes at least: a stacked display body layer and an encapsulation layer; the encapsulation layer includes: a first inorganic layer and a first organic layer; the first inorganic layer is located between the display body layer and the first organic layer; and further includes: at least one supporting member; at least one opening for accommodating the supporting member is provided in the first organic layer, and the extension direction of the opening is along the thickness direction of the display module; wherein the supporting member is located in the non-luminous area of ​​the display module.

[0017] The display module provided in the embodiments of the present application has at least one opening extending along the thickness of the display module in a first organic layer, and a support member disposed within the opening. The first organic layer is made of a relatively soft organic material, and the support member can provide a certain degree of support for the first organic layer along the thickness of the display module, thereby improving the impact resistance of the display module. In this way, when the display module is bent or subjected to external impact, problems such as cracks or bright spots in the display module can be avoided or alleviated, thereby improving the display quality of the display screen and, in turn, enhancing the visual experience of consumers when using electronic devices.

[0018] In one possible implementation of the second aspect, the dimension of the support member in the thickness direction of the display module is less than or equal to the thickness of the first organic layer. The dimension of the support member in the thickness direction of the display module is no greater than the thickness of the first organic layer, thereby preventing the support member from protruding from the first organic layer in the thickness direction of the display module, thereby ensuring the structural aesthetics of the display module. Furthermore, the dimension of the support member in the thickness direction of the display module is less than or equal to the thickness of the first organic layer. The first organic layer is made of a relatively soft organic material. Thus, when the first organic layer is squeezed, the support member can provide good support and cushioning.

[0019] In one possible implementation of the second aspect, the encapsulation layer further includes a second inorganic layer; the second inorganic layer is located on a side of the first organic layer facing away from the first inorganic layer. By covering the second inorganic layer on a side of the first organic layer facing away from the first inorganic layer, the second inorganic layer can protect the first organic layer, thereby further improving the bending reliability and impact resistance of the display module.

[0020] In one possible implementation of the first or second aspect, the display module further includes at least one touch structure located on a side of the second inorganic layer facing away from the first organic layer. Providing at least one touch structure within the display module ensures that the display screen having the display module can achieve touch functionality.

[0021] In a possible implementation of the first or second aspect, the encapsulation layer further includes a second barrier disposed around the first inorganic layer and the first organic layer. The first organic layer is made of a relatively soft organic material. The second barrier disposed around the first organic layer encloses the first organic layer within the accommodation space formed by the first barrier and the first inorganic layer. This prevents excessive compression of the first organic layer when the display module is bent or subjected to external impact, thereby preventing or mitigating severe deformation of the display module.

[0022] In a possible implementation of the first aspect or the second aspect, an outer edge of the second blocking member is flush with an outer edge of the display body layer, thereby ensuring the structural aesthetics of the display module.

[0023] In a possible implementation of the first aspect or the second aspect, the first inorganic layer includes: a first part, a second part and a third part; one end of the second part is connected to the first part, and the other end of the second part is connected to the third part; the first part and the second part are located on a side of the second blocking member facing the first organic layer, and the third part is located on a side of the second blocking member facing the second inorganic layer.

[0024] By designing the first inorganic layer into three connected parts, the first part of the first inorganic layer covers one side of the display body layer, the second part and the third part of the first inorganic layer cover the second blocking member, and the first organic layer uses organic material, which is relatively soft. By arranging the second blocking member around the first organic layer, the second blocking member encloses the first organic layer in the accommodation space formed by the first inorganic layer. When the display module is bent or subjected to external impact, the first organic layer can be prevented from being excessively squeezed, thereby avoiding or reducing serious deformation of the display module.

[0025] In a possible implementation of the first or second aspect, the display body layer includes a stacked base layer and a light-emitting layer; the light-emitting layer is located between the encapsulation layer and the base layer. The base layer can provide support for the entire display module, and the light-emitting layer can realize the display module's light-emitting function.

[0026] In a possible implementation of the first or second aspect, the base layer includes: a first substrate layer, a circuit layer, and a second substrate layer; the circuit layer is located between the first and second substrate layers, and the second substrate layer is located between the circuit layer and the light-emitting layer. The circuit layer can implement the logic functions of the display module.

[0027] In a possible implementation of the first aspect or the second aspect, the device further includes: a polarizer, wherein the polarizer is located on a side of the encapsulation layer facing away from the display body layer. The polarizer can help adjust the optical mode of the display module.

[0028] In a possible implementation of the first or second aspect, the device further includes a cover layer, wherein the polarizer is located between the encapsulation layer and the cover layer. The cover layer protects the polarizer from external damage or abrasion, thereby preventing the polarizer from affecting the performance of the display module.

[0029] In a third aspect, an embodiment of the present application provides a display screen, which at least includes: a glass cover plate and any of the display modules described above; the glass cover plate is covered on the display module.

[0030] The display screen provided in the embodiment of the present application includes at least a display module and a glass cover plate covering the display module. The display module is capable of improving the reliability of the display module by providing a second organic layer above the first organic layer. The second organic layer uses an organic material. In this way, when the display module is bent or subjected to external impact, problems such as cracks or bright spots in the display module can be avoided or reduced, thereby improving the display effect of the display screen and further enhancing the visual experience of consumers when using electronic devices.

[0055] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0056] The embodiments of the present application provide an electronic device, which may include but is not limited to mobile or fixed terminals with display screens, such as mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), handheld computers, touch-screen TVs, walkie-talkies, netbooks, point-of-sales (POS) machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, wireless USB flash drives, Bluetooth speakers / headphones / glasses, in-vehicle pre-installed devices, driving recorders, and security equipment.

[0057] In the embodiment of the present application, a mobile phone is used as an example for the electronic device. The mobile phone provided in the embodiment of the present application can be a curved screen mobile phone or a flat screen mobile phone, a straight screen mobile phone or a folding screen mobile phone (for example, see Figure 7 The water drop shape folding screen mobile phone shown in the figure) is used as an example to illustrate the embodiments of this application.

[0058] Reference Figures 1 to 3 As shown, taking the electronic device as a foldable screen mobile phone 200 as an example, the foldable screen mobile phone 200 may include: a first structural member 220 and a second structural member 230, with a bending zone between the first structural member 220 and the second structural member 230. For example, a rotating shaft assembly 240 may be provided in the bending zone, and the rotating shaft assembly 240 is located between the first structural member 220 and the second structural member 230. The first structural member 220 and the second structural member 230 are rotatably connected via the rotating shaft assembly 240 to achieve folding and unfolding of the first structural member 220 and the second structural member 230.

[0059] In the embodiments of this application, Figure 2 or Figure 3 As shown, the foldable screen mobile phone 200 may further include: a display screen 210, wherein the display screen 210 may be a flexible display screen, and the flexible display screen may cover one side of the first structural member 220, the hinge assembly 240, and the second structural member 230. In this way, the flexible display screen may be folded or unfolded in response to the rotation of the first structural member 220 and the second structural member 230. For example, when the first structural member 220 and the second structural member 230 rotate toward each other to the folded state (see Figure 1 As shown in FIG, the flexible display screen of the folding screen mobile phone 200 is also in a folded state and is located between the first structural member 220 and the second structural member 230. When the first structural member 220 and the second structural member 230 are rotated away from each other to the unfolded state (see FIG. Figure 3 As shown), until the first structural member 220 and the second structural member 230 are located on the same horizontal plane, the flexible display screen of the folding screen mobile phone 200 is also in the unfolded state.

[0060] In the embodiment of the present application, since the display screen 210 needs to be foldable, the display screen 210 may be a flexible display screen, for example, the flexible display screen may be an organic light-emitting diode (OLED) display screen.

[0061] It should be noted that the number of structural members in the foldable screen mobile phone 200 can be two (see Figures 1 to 3When there are two or more structural members, adjacent structural members can rotate about mutually parallel rotating shaft assemblies 240 to form a multi-layer structure or to obtain a larger display area after unfolding. In the embodiments of the present application, the foldable screen mobile phone 200 is mainly described as having two structural members (i.e., first structural member 220 and second structural member 230).

[0062] Furthermore, the folding screen mobile phone 200 may further include: a back cover 250, such as Figure 1 or Figure 2 As shown, the back cover 250 is located on a surface of the first structural member 220 , the hinge assembly 240 and the second structural member 230 facing away from the display screen 210 . For example, the first structural member 220 , the hinge assembly 240 and the second structural member 230 are all located between the display screen 210 and the back cover 250 .

[0063] It is understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device. In other embodiments of the embodiments of the present application, the electronic device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. For example, the folding screen mobile phone 200 may also include devices such as a camera module and a flash. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0064] In addition, refer to Figure 4 As shown, the display screen 210 includes at least a display module 100 and a glass cover plate 211, wherein the glass cover plate 211 can be located above the display module 100. Specifically, the glass cover plate 211 can cover the display module 100, and the size of the glass cover plate 211 can be greater than or equal to the size of the display module 100.

[0065] In the embodiment of the present application, the display module 100 and the glass cover plate 211 can be connected by an adhesive layer. Specifically, the display module 100 and the glass cover plate 211 can be bonded by optical clear adhesive (OCA). Of course, in some other examples, the display module 100 and the glass cover plate 211 can also be bonded to each other in other ways. For example, the display module 100 and the glass cover plate 211 can be hot-pressed to form the display screen 210.

[0066] The display module 100 generally includes a substrate layer, a light-emitting layer, an encapsulation layer, and a touch layer, which are stacked in sequence. The encapsulation layer includes an organic encapsulation layer and an inorganic encapsulation layer. The inorganic encapsulation layer is located between the light-emitting layer and the organic encapsulation layer, and the organic encapsulation layer is located between the inorganic encapsulation layer and the touch layer. However, if the display screen is bent or subjected to external impact (such as being dropped, pressed by a finger, or clicked by a pen), the display module is prone to cracks or bright spots, which can affect the display quality and, in turn, the consumer's visual experience when using the electronic device.

[0067] Based on this, an embodiment of the present application provides a new display module 100, which can be applied to electronic devices with a display screen (such as mobile phones or computers, etc.) to solve the above technical problems.

[0068] The specific structure of the display module 100 will be described in detail below with reference to specific drawings and taking different embodiments as examples.

[0069] Example 1

[0070] Reference Figure 5 and Figure 6 As shown, an embodiment of the present application provides a display module 100 , which can be applied to a display screen 210 (eg, a flexible display screen). Specifically, the display module 100 can include at least: a stacked display body layer 110 and an encapsulation layer 120 .

[0071] The encapsulation layer 120 may include a first inorganic layer 121 , a first organic layer 122 and a second organic layer 123 . The first inorganic layer 121 is located between the display body layer 110 and the first organic layer 122 . The first organic layer 122 is located between the first inorganic layer 121 and the second organic layer 123 .

[0072] By providing a second organic layer 123 above the first organic layer 122, and the second organic layer 123 uses an organic material, the reliability of the display module 100 can be improved. In this way, when the display module 100 is bent or subjected to external impact, problems such as cracks or bright spots in the display module 100 can be avoided or reduced, thereby improving the display effect of the display screen and further enhancing the visual experience of consumers when using electronic devices.

[0073] It is understood that in the embodiment of the present application, the materials used for the first organic layer 122 and the second organic layer 123 can be organic materials. Specifically, the first organic layer 122 and the second organic layer 123 can be formed using inkjet printing (IJP). For example, the first organic layer 122 and the second organic layer 123 can be made of a resin material, such as polyimide (PI). This embodiment of the present application is not limited to this, nor is it limited to the above example.

[0074] Continue to refer to Figure 5 and Figure 6 As shown, in the embodiment of the present application, the encapsulation layer 120 may further include: a first barrier 124 , wherein the first barrier 124 may be disposed around the second organic layer 123 .

[0075] The second organic layer 123 is made of an organic material, which is relatively soft. By arranging a first blocking member 124 around the second organic layer 123, the first blocking member 124 encloses the second organic layer 123 within the accommodation space formed by the first blocking member 124. When the display module 100 is bent or subjected to external impact, the second organic layer 123 can be prevented from being excessively squeezed, thereby avoiding or reducing serious deformation of the display module 100.

[0076] It should be noted that the material used for the first blocking member 124 may be silicon nitride or the like, and the embodiment of the present application is not limited to this, nor is it limited to the above example.

[0077] Among them, in a possible implementation, such as Figure 6 and Figure 7 As shown, the outer edge of the first blocking member 124 can be flush with the outer edge of the display body layer 110. In this way, the structural aesthetics of the display module 100 can be ensured.

[0078] Additionally, in some embodiments, Figure 8 and Figure 9 As shown, the projection area of ​​the second organic layer 123 on the display body layer 110 can be smaller than the projection area of ​​the first organic layer 122 on the display body layer 110, wherein the projection area of ​​the second organic layer 123 on the display body layer 110 can be located in the weak area of ​​the display module 100.

[0079] By setting a second organic layer 123 in the weak area of ​​the display module 100, and the second organic layer 123 uses an organic material, the reliability of the weak area of ​​the display module 100 can be improved, and then the overall reliability of the display module 100 can be improved. In this way, when the display module 100 is bent or subjected to external impact, problems such as cracks or bright spots in the display module 100 can be avoided or alleviated.

[0080] Specifically, continue to refer to Figure 8 and Figure 9 As shown, in the embodiment of the present application, a surface of the second organic layer 123 facing away from the first organic layer 122 may be arched.

[0081] By designing the side of the second organic layer 123 facing away from the first organic layer 122 (i.e., the side of the second organic layer 123 facing the front of the display module 100) to be arched, the structural strength of the display module 100 can be further increased when it is bent or subjected to external impact, thereby further increasing the overall reliability of the display module 100.

[0082] It should be noted that, in some other embodiments, the shape of the second organic layer 123 may also be any shape such as a rectangle or a semicircle. The embodiment of the present application does not limit the specific shape of the second organic layer 123 and is not limited to the above examples.

[0083] In the embodiment of the present application, the encapsulation layer 120 may further include: a second inorganic layer 125 (see Figure 9 As shown), the second inorganic layer 125 may be located between the first organic layer 122 and the second organic layer 123.

[0084] By setting a second inorganic layer 125 between the first organic layer 122 and the second organic layer 123, the first organic layer 122 and the second organic layer 123 use organic materials, which are relatively soft, and the second inorganic layer 125 uses inorganic materials, which are relatively hard. The second inorganic layer 125 can separate the first organic layer 122 and the second organic layer 123, and can improve the structural strength of the first organic layer 122 and the second organic layer 123 stacked together, thereby increasing the overall structural strength of the display module 100.

[0085] like Figure 8 or Figure 9 As shown, in the embodiment of the present application, the encapsulation layer 120 may further include: a third inorganic layer 126 , and the third inorganic layer 126 is located on a surface of the second organic layer 123 facing away from the first organic layer 122 .

[0086] By covering the second organic layer 123 on the side facing away from the first organic layer 122 with the third inorganic layer 126, the third inorganic layer 126 protects the second organic layer 123, thereby further improving the bending reliability and impact resistance of the display module 100. Furthermore, the third inorganic layer 126, located on the surface of the display module 100, also provides waterproofing and oxidation resistance.

[0087] Alternatively, in some embodiments, Figure 8As shown, the encapsulation layer 120 may include the third inorganic layer 126, but does not include the second inorganic layer 125. That is, the second organic layer 123 may be directly disposed on the first organic layer 122 (see Figure 8 As shown), a second inorganic layer 125 may be provided on the first organic layer 122, and then a second organic layer 123 may be provided on the second inorganic layer 125 (see Figure 9 shown).

[0088] It can be understood that, in the embodiment of the present application, the materials used for the first inorganic layer 121 , the second inorganic layer 125 and the third inorganic layer 126 can be inorganic materials.

[0089] Specifically, the first inorganic layer 121, the second inorganic layer 125, and the third inorganic layer 126 can be formed by chemical vapor deposition (CVD). For example, the first inorganic layer 121, the second inorganic layer 125, and the third inorganic layer 126 can be made of silicon nitride or silicon oxide, etc. This embodiment of the present application is not limited to this and is not limited to the above example.

[0090] In the embodiments of this application, Figure 7 As shown, the display module 100 may further include at least one touch structure 140, wherein the touch structure 140 may be located on a surface of the second inorganic layer 125 facing away from the first organic layer 122. By providing at least one touch structure 140 within the display module 100, the display screen having the display module 100 can be ensured to have a touch function.

[0091] In addition, the encapsulation layer 120 may further include a second barrier 127 , wherein the second barrier 127 is disposed around the first inorganic layer 121 and the first organic layer 122 .

[0092] The first organic layer 122 is made of an organic material, which is relatively soft. By arranging a second blocking member 127 around the first organic layer 122, the second blocking member 127 encloses the first organic layer 122 in the accommodation space formed by the first blocking member 124 and the first inorganic layer 121. When the display module 100 is bent or subjected to external impact, the first organic layer 122 can be prevented from being excessively squeezed, thereby avoiding or reducing serious deformation of the display module 100.

[0093] It should be noted that the material used for the second blocking member 127 can be the same as the material used for the first blocking member 124. For example, the material used for the first blocking member 124 can be silicon nitride, etc., which is not limited to the embodiment of the present application and is not limited to the above example.

[0094] In one possible implementation, the outer edge of the second blocking member 127 may be flush with the outer edge of the display body layer 110. In this way, the structural aesthetics of the display module 100 can be ensured.

[0095] like Figure 6 and Figure 7 As shown, in an embodiment of the present application, the first inorganic layer 121 may include: a first part 1211, a second part 1212 and a third part 1213, wherein one end of the second part 1212 is connected to the first part 1211, and the other end of the second part 1212 is connected to the third part 1213, and the first part 1211 and the second part 1212 are located on the side of the second blocking member 127 facing the first organic layer 122, and the third part 1213 is located on the side of the second blocking member 127 facing the second inorganic layer 125.

[0096] By designing the first inorganic layer 121 as three connected parts, the first part 1211 of the first inorganic layer 121 covers one side of the display body layer 110, the second part 1212 and the third part 1213 of the first inorganic layer 121 cover the second blocking member 127, and the first organic layer 122 uses organic material, which is relatively soft. By arranging the second blocking member 127 around the first organic layer 122, the second blocking member 127 encloses the first organic layer 122 in the accommodating space formed by the first inorganic layer 121. When the display module 100 is bent or subjected to external impact, the first organic layer 122 can be prevented from being excessively squeezed, thereby avoiding or reducing serious deformation of the display module 100.

[0097] In the embodiment of the present application, the display body layer 110 may include a stacked base layer 111 and a light-emitting layer 112, wherein the light-emitting layer 112 may be located between the encapsulation layer 120 and the base layer 111. The base layer 111 can provide support for the entire display module 100, and the light-emitting layer 112 can realize the light-emitting function of the display module 100.

[0098] Specifically, the base layer 111 may include a first substrate layer 1111, a circuit layer 1112, and a second substrate layer 1113. The circuit layer 1112 is located between the first substrate layer 1111 and the second substrate layer 1113, and the second substrate layer 1113 is located between the circuit layer 1112 and the light-emitting layer 112. The circuit layer 1112 can implement the logic functions of the display module 100.

[0099] In some embodiments, the circuit layer 1112 may be, for example, a transistor circuit.

[0100] In addition, it should be noted that see Figure 7As shown, the light emitting layer 112 may include: a light emitting layer body 1121 and at least one light emitting element 1122, wherein the at least one light emitting element 1122 may be spaced apart and distributed within the light emitting layer body 1121. For example, Figure 7 In the embodiment, the number of the light emitting elements 1122 is five, and the five light emitting elements 1122 can be distributed at intervals within the light emitting layer body 1121 .

[0101] In the embodiment of the present application, the display module 100 may further include a polarizer 150 , which may be located on a side of the encapsulation layer 120 facing away from the display body layer 110 . The polarizer 150 may help adjust the optical mode of the display module 100 .

[0102] In addition, in the embodiment of the present application, the display module 100 may further include a cover layer 160, and the polarizer 150 may be located between the encapsulation layer 120 and the cover layer 160. The cover layer 160 can protect the polarizer 150, preventing external damage or abrasion to the polarizer 150, which may affect the performance of the display module 100.

[0103] In one possible implementation, the polarizer 150 and the cover layer 160 may be connected via an adhesive layer. The adhesive layer may be made of optical clear adhesive (OCA), which is transparent and has good optical properties.

[0104] Of course, in some other examples, the polarizer 150 and the cover layer 160 may be bonded to each other in other ways, for example, the polarizer 150 and the cover layer 160 may be connected by heat pressing.

[0105] Example 2

[0106] The embodiment of the present application also provides a display module 100 with another structure, which can also be applied to a display screen 210 (such as a flexible display screen). Compared with the first embodiment, the difference between the second embodiment and the second embodiment is that the specific structure of the encapsulation layer 120 in the display module 100 is different.

[0107] Reference Figure 10 As shown, the display module 100 may include at least: a stacked display body layer 110 and an encapsulation layer 120 . Specifically, the encapsulation layer 120 may include: a first inorganic layer 121 and a first organic layer 122 , wherein the first inorganic layer 121 is located between the display body layer 110 and the first organic layer 122 .

[0108] In an embodiment of the present application, the display module 100 may further include: at least one support member 130, at least one opening for accommodating the support member 130 is opened in the first organic layer 122, and the extension direction of the opening is along the thickness direction of the display module 100, wherein the support member 130 is located in the non-luminous area of ​​the display module 100.

[0109] By defining at least one opening extending along the thickness of the display module 100 within the first organic layer 122 and disposing a support member 130 within the opening, and by using a relatively soft organic material, the support member 130 can provide a certain degree of support for the first organic layer 122 along the thickness of the display module 100, thereby improving the impact resistance of the display module 100. This prevents or mitigates problems such as cracks or bright spots in the display module 100 when it is bent or subjected to external impact, thereby improving the display quality of the display screen and, in turn, enhancing the visual experience of consumers when using electronic devices.

[0110] The number of the supporting members 130 may be one, two, three or more, and the present application embodiment does not limit this, nor is it limited to the above examples. Figure 10 As shown, there are four support members 130 , and four openings extending along the thickness direction of the display module 100 are defined in the first organic layer 122 . The four support members 130 can be located in the four openings respectively.

[0111] It is understandable that, in the embodiment of the present application, the material used for the support member 130 may be a material with a high elastic modulus, so as to ensure good supporting and buffering performance for the first organic layer 122 .

[0112] In some embodiments, the elastic modulus of the material used for the support member 130 may be greater than the elastic modulus of the material used for the first organic layer 122. In this way, when the display module 100 is impacted or squeezed by the outside world, the support member 130 is arranged in the opening of the first organic layer 122, which helps to increase the creep recovery force of the display module 100.

[0113] In the embodiment of the present application, the dimension of the support member 130 in the thickness direction of the display module 100 may be less than or equal to the thickness of the first organic layer 122 .

[0114] The dimension of the support member 130 in the thickness direction of the display module 100 is no greater than the thickness of the first organic layer 122 , which can prevent the support member 130 from protruding from the first organic layer 122 in the thickness direction of the display module 100 , thereby ensuring the structural aesthetics of the display module 100 .

[0115] In addition, the dimension of the support member 130 in the thickness direction of the display module 100 is less than or equal to the thickness of the first organic layer 122. The first organic layer 122 is made of organic material, which is relatively soft. In this way, when the first organic layer 122 is squeezed, the support member 130 can play a good supporting and buffering role.

[0116] Continue to refer to Figure 10 As shown, in the embodiment of the present application, the encapsulation layer 120 may further include: a second inorganic layer 125 , wherein the second inorganic layer 125 is located on a surface of the first organic layer 122 facing away from the first inorganic layer 121 .

[0117] By covering the second inorganic layer 125 on the side of the first organic layer 122 facing away from the first inorganic layer 121 , the second inorganic layer 125 can protect the first organic layer 122 , thereby further improving the bending reliability and impact resistance of the display module 100 .
