[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of this application. (Reference) Figure 1 As can be seen, the display module 10 may include a display panel 101 and a protective layer 102.

[0054] The display panel 101 has an irregular shape and includes a display surface and a non-display surface opposite to it. A protective layer 102 is located on and connected to the non-display surface of the display panel 101. This protective layer 102 is used to prevent damage to the non-display surface of the display panel 101. Figure 1 An exploded view is used to illustrate the module in order to clearly show the display panel 101 and the protective layer 102.

[0055] refer to Figure 1 The protective layer 102 has the same shape as the display panel 101. This can mean that the protective layer 102 is exactly the same as the display panel 101, or that the shape of the protective layer 102 has slight differences from the shape of the display panel 101.

[0056] For example, since the protective layer 102 is located on the non-display surface of the display panel 101, if there are certain devices on the non-display surface of the display panel 101, the protective layer 102 can be perforated at the corresponding location to avoid the devices located on the non-display surface of the display panel 101.

[0057] Since the display panel 101 has an irregular shape, the protective layer 102 can also have an irregular shape. For example, Figure 1 The display panel 101 is "I" shaped, and correspondingly, for example Figure 1 The protective layer 102 is also I-shaped. Of course, the display panel 101 can also be other shapes, and this application embodiment does not limit this.

[0058] In summary, this application provides a display module in which the display panel has an irregular shape, and the protective layer connected to the non-display surface of the display panel also has an irregular shape. Therefore, this protective layer can protect the non-display surface of the display panel, making it less susceptible to damage.

[0059] In this embodiment, the protective layer 102 in the display module 10 can be prepared by machining.

[0060] Typically, the display panel 101 in the display module 10 is rectangular, and correspondingly, the protective layer 102 can also be rectangular. The rectangular protective layer 102 can be fabricated using appropriate molds, resulting in high fabrication efficiency and facilitating large-scale production. However, since the display panel 101 in the display module 10 provided in this embodiment is irregularly shaped (non-rectangular), a protective layer 102 of a corresponding shape needs to be provided on the non-display surface of this irregularly shaped display panel 101. Because the fabrication cost of the mold for the protective layer 102 is high, and the demand for irregularly shaped display panels 101 is low, using a mold to fabricate the corresponding protective layer 102 leads to a higher cost for the display module.

[0061] Therefore, the protective layer 102 in the display module 10 provided in this application embodiment can be prepared by machining. This not only protects the non-display surfaces of the display panel 101 but also avoids the high cost of the display module caused by using molds to prepare the protective layer 102. Furthermore, when preparing the protective layer 102 by machining, it is not limited by the shape of the protective layer 102, and protective layers 102 of corresponding shapes can be prepared based on display panels 101 with different shape requirements, which is convenient for protecting the non-display surfaces of irregularly shaped display panels 101 with a small number of requirements.

[0062] Optionally, machining mainly includes CNC machining and manual machining. The machining in this embodiment can be CNC machine tool machining or manual conventional machine tool machining. The machine tools include lathes, milling machines, and grinding machines, etc.

[0063] To ensure the machining accuracy and speed of the protective layer 102, a CNC machine tool can typically be used to machine the protective layer 102. That is, the protective layer 102 in the display module 10 provided in this application embodiment can be prepared by CNC machine tool machining.

[0064] Optionally, the material of the protective layer 102 can be a composite material, polycarbonate (PC), stainless steel, or carbon fiber, etc.

[0065] Among them, carbon fiber material has good rigidity, low room temperature creep, small dimensional change, and good performance when prepared by machining (such as good flatness), making it suitable as a protective material for the non-display surface of the display panel 101. Therefore, the material of the protective layer 102 in the display module 10 provided in this application embodiment can be carbon fiber material.

[0066] In this embodiment, the protective layer 102 can be a plate-like structure to avoid the protective layer 102 occupying too much space when it is connected to the non-display surface of the display panel 101. Furthermore, designing the protective layer 102 as a plate-like structure can reduce the space occupied by the display module, making it easier to install and carry.

[0067] Optionally, the thickness of the protective layer 102 can range from 0.5 mm to 4 mm. Further, the thickness of the protective layer 102 can range from 0.5 mm to 1 mm.

[0068] Figure 2 This is a schematic diagram of another display module provided in an embodiment of this application. (Reference) Figure 2 As can be seen, the display module 10 may include at least one connector 103. The connector 103 is used for fixed connection with the housing of the display device. By designing at least one connector 103 in the display module 10, the assembly and disassembly of the display module 10 and the housing can be easily realized, the operation is simple, and the assembly and disassembly efficiency is high.

[0069] Optionally, at least a portion of each connector 103 may be located on the side of the protective layer 102 away from the display panel 101, and the position of each connector 103 relative to the protective layer 102 and the display panel 101 is fixed. Thus, the side of the protective layer 102 away from the display panel 101 can be fixedly connected to the housing through the connector 103, thereby realizing the fixed connection between the display module 10 and the housing.

[0070] Optionally, the display module 10 may include a plurality of connectors 103, which are evenly distributed on one side of the protective layer 102. By designing a plurality of connectors 103 and making them evenly distributed, it is easier to ensure that the connection between each connector 103 and different positions of the housing is uniform and reliable.

[0071] As one possible scenario, refer to Figure 3 The protective layer 102 may have at least one first hole 102a and at least one second hole 102b corresponding to the at least one first hole 102a. The diameter of each first hole 102a is smaller than the diameter of the corresponding second hole 102b, and each first hole 102a communicates with the corresponding second hole 102b. Furthermore, the second hole 102b is closer to the display panel 101 than the first hole 102a. Figure 3 The image shows a first hole 102a and a corresponding second hole 102b.

[0072] refer to Figure 4 The connector 103 may include a first portion 1031 and a second portion 1032 fixedly connected to the first portion 1031. The projection of the second portion 1032 in the target plane lies within the projection of the second hole 102b in the target plane and covers the projection of the first hole 102a in the target plane. The projection of the first portion 1031 in the target plane lies within the projection of the first hole 102a in the target plane.

[0073] refer to Figure 5 The second part 1032 is located inside the second hole 102b, and the end of the first part 1031 near the second part 1032 is located inside the first hole 102a, while the end of the first part 1031 away from the second part 1032 is located on the side of the protective layer 102 away from the display panel 101. The target plane X is perpendicular to the axis Y of the first hole 102a.

[0074] The projection of the second portion 1032 onto the target plane X lies within the projection of the second hole 102b onto the target plane X, and covers the projection of the first hole 102a onto the target plane X. This indicates that the size of the second portion 1032 is smaller than the size of the second hole 102b, but larger than the size of the first hole 102a. Similarly, the projection of the first portion 1031 onto the target plane X lies within the projection of the first hole 102a onto the target plane X. This indicates that the size of the first portion 1031 is smaller than the size of the first hole 102a. Therefore, when the second portion 1032 is located in the second hole 102b and the first portion 1031 is located in the first hole 102a, the connector 103 will not detach from the side of the first hole 102a away from the second hole 102b, ensuring the reliability of the connection between the connector 103 and the housing.

[0075] Optional, see reference Figure 4 The first part 1031 can be a rod-like structure, and the second part 1032 can be a plate-like structure. The extension direction of the first part 1031 intersects the plane containing the second part 1032. For example, the extension direction of the first part 1031 is perpendicular to the plane containing the second part 1032.

[0076] refer to Figure 4 and Figure 5 The first portion 1031 has a third hole 1031a, the axis of which is parallel to the extending direction of the first portion 1031. For example, the axis of the third hole 1031a is collinear with the axis of the first portion 1031.

[0077] The third hole 1031a, at least a portion of which is away from the display panel 101, has internal threads. For example, the interior of the third hole 1031a near the second portion 1032 may not have internal threads, while the interior away from the second portion 1032 may have internal threads. A connecting screw passes through a hole in the housing and connects to the third hole 1031a to fix the connector 103 to the housing, thereby fixing the display module 10 to the housing. In this case, the connector 103 can be an embedded nut.

[0078] refer to Figure 5 The third hole 1031a can penetrate the first portion 1031. Of course, the third hole 1031a may not penetrate the first portion 1031; this embodiment does not limit this. (See reference...) Figure 5 The second part 1032 may have a fourth hole 1032a. When the third hole 1031a penetrates the first part 1031, the third hole 1031a may be connected to the fourth hole 1032a.

[0079] As another possibility, the first hole 102a and the second hole 102b are not designed on the protective layer 102, and the connector 103 is directly fixedly connected to the side of the protective layer 102 away from the display panel 101.

[0080] Optionally, if the connector 103 is a nut, a connecting screw passes through a hole in the housing and connects to the connector 103 to securely connect the display module 10 to the housing. If the connector 103 is a screw, the screw passes through a hole in the housing and is then secured to the connecting nut.

[0081] Optionally, after the protective layer 102 is prepared by machining, multiple connectors 103 can be connected to one side of the protective layer 102. For example, the connectors 103 can be directly welded to one side of the protective layer 102.

[0082] In this embodiment, the connector 103 can be made of metal. This ensures the rigidity and stability of the connector 103, thereby guaranteeing the reliability of the connection between the connector 103 and the housing.

[0083] refer to Figure 2 and Figure 6 As can be seen, the display module 10 may also include a connection layer 104. The connection layer 104 may be located between the display panel 101 and the protective layer 102, and is used to connect the display panel 101 and the protective layer 102.

[0084] Optionally, the connecting layer 104 can be an adhesive layer. That is, the non-display surface of the display panel 101 is bonded to the protective layer 102 through the adhesive layer to ensure the reliability of the connection between the display panel 101 and the protective layer 102.

[0085] When installing the display module 10, the first part 1031 of the connector 103 can be passed through one side of the second hole 102b, so that the second part 1032 of the connector 103 is located inside the second hole 102b, the end of the first part 1031 near the second part 1032 is located inside the first hole 102a, and the end of the first part 1031 away from the second part 1032 is located on the side of the protective layer 102 away from the display panel 101. Then, the non-display surface of the display panel 101 and the side of the protective layer 102 with the second hole 102b are bonded together by the connecting layer 104, so that the display panel 101, the protective layer 102, and the connector 103 form a whole.

[0086] In this embodiment, the display panel 101 includes a substrate and a driving board, which can be connected by a flexible circuit board.

[0087] In summary, this application provides a display module in which the display panel has an irregular shape, and the protective layer connected to the non-display surface of the display panel also has an irregular shape. Therefore, this protective layer can protect the non-display surface of the display panel, making it less susceptible to damage.

[0088] Figure 7 This is a flowchart illustrating a method for manufacturing a display module according to an embodiment of this application. This method can be used to manufacture the display module 10 provided in the above embodiment. (Reference) Figure 7 As can be seen, this method may include:

[0089] Step 201: Provide a display panel.

[0090] In this embodiment of the application, when preparing the display module, a display panel 101 with an irregular shape can be obtained first. The display panel 101 may have a display surface and a non-display surface opposite to the display surface.

[0091] Step 202: Form a protective layer.

[0092] In this embodiment, the protective layer 102 can be used to protect the non-display surface of the display panel 101. The shape of the protective layer 102 is the same as the shape of the display panel 101. This can mean that the shape of the protective layer 102 is exactly the same as the shape of the display panel 101, or that the shape of the protective layer 102 has slight differences from the shape of the display panel 101.

[0093] Step 203: Connect the protective layer to the non-display side of the display panel.

[0094] In this embodiment of the application, after obtaining the display panel 101 and preparing the protective layer 102, the protective layer 102 can be disposed on the non-display surface of the display panel 101 and connected to the non-display surface of the display panel 101 so that the protective layer 102 protects the non-display surface of the display panel 101 and prevents damage to the non-display surface of the display panel 101.

[0095] In summary, this application provides a method for manufacturing a display module. The display panel in the display module prepared by this method has an irregular shape, and the protective layer connected to the non-display surface of the display panel also has an irregular shape. Therefore, this protective layer can protect the non-display surface of the display panel, making it less susceptible to damage.

[0096] Figure 8 This is a flowchart illustrating another method for manufacturing a display module according to an embodiment of this application. This method can be used to manufacture the display module 10 provided in the above embodiments. (Reference) Figure 8 The method may include:

[0097] Step 301: Provide a display panel.

[0098] In this embodiment of the application, when preparing the display module 10, a display panel 101 with an irregular shape can be obtained first. The display panel 101 may have a display surface and a non-display surface opposite to the display surface.

[0099] Step 302: Form a protective layer by machining.

[0100] In this embodiment, the protective layer 102 can be used to protect the non-display surface of the display panel 101. The shape of the protective layer 102 is the same as the shape of the display panel 101. This can mean that the shape of the protective layer 102 is exactly the same as the shape of the display panel 101, or that the shape of the protective layer 102 has slight differences from the shape of the display panel 101.

[0101] Typically, the display panel 101 in the display module 10 is rectangular, and correspondingly, the protective layer 102 can also be rectangular. The rectangular protective layer 102 can be fabricated using appropriate molds, resulting in high fabrication efficiency and facilitating large-scale production. However, since the display panel 101 in the display module 10 required in this embodiment is irregularly shaped (non-rectangular), a protective layer 102 of a corresponding shape needs to be provided on the non-display surface of this irregularly shaped display panel 101. Because the fabrication cost of the mold for the protective layer 102 is high, and the demand for irregularly shaped display panels 101 is low, using a mold to fabricate the corresponding protective layer 102 leads to a higher cost for the display module 10.

[0102] Therefore, the protective layer 102 corresponding to the irregularly shaped display panel 101 can be prepared by machining in this embodiment. This not only protects the non-display surfaces of the display panel 101 but also avoids the high cost of the display module 10 caused by using molds to prepare the protective layer 102. Furthermore, when preparing the protective layer 102 by machining, it is not limited by the shape of the protective layer 102, and can prepare protective layers 102 of corresponding shapes based on display panels 101 with different shape requirements, facilitating the protection of the non-display surfaces of irregularly shaped display panels 101 with limited demand.

[0103] Furthermore, the protective layer 102 may have at least one first hole 102a and at least one second hole 102b corresponding to the at least one first hole 102a. The diameter of each first hole 102a is smaller than the diameter of the corresponding second hole 102b, and each first hole 102a communicates with the corresponding second hole 102b. The second hole 102b is closer to the display panel 101 than the first hole 102a. Figure 3 The image shows a first hole 102a and a corresponding second hole 102b.

[0104] Step 303: Connect at least one connector to the protective layer.

[0105] In this embodiment, the connector 103 may include a first portion 1031 and a second portion 1032 fixedly connected to the first portion 1031. The projection of the second portion 1032 onto the target plane X lies within the projection of the second hole 102b onto the target plane X, and covers the projection of the first hole 102a onto the target plane X. The projection of the first portion 1031 onto the target plane X lies within the projection of the first hole 102a onto the target plane X.

[0106] When connecting the connector 103 to the protective layer 102, the first portion 1031 of the connector 103 can pass through one side of the second hole 102b of the protective layer 102, such that the second portion 1032 is located within the second hole 102b, the end of the first portion 1031 near the second portion 1032 is located within the first hole 102a, and the end of the first portion 1031 away from the second portion 1032 is located on the side of the protective layer 102 away from the display panel 101. The target plane X is perpendicular to the axis of the first hole 102a.

[0107] The projection of the second portion 1032 onto the target plane X lies within the projection of the second hole 102b onto the target plane X, and covers the projection of the first hole 102a onto the target plane X. This indicates that the size of the second portion 1032 can be smaller than the size of the second hole 102b, but larger than the size of the first hole 102a. Furthermore, the projection of the first portion 1031 onto the target plane X lies within the projection of the first hole 102a onto the target plane X. This indicates that the size of the first portion 1031 is smaller than the size of the first hole 102a. Therefore, when the second portion 1032 is located in the second hole 102b and the first portion 1031 is located in the first hole 102a, the connector 103 will not detach from the side of the first hole 102a away from the second hole 102b, ensuring the reliability of the connection between the connector 103 and the housing.

[0108] Step 304: Connect one side of the protective layer to the non-display side of the display panel through the connecting layer.

[0109] In this embodiment, the side of the protective layer 102 with the second hole 102b can be connected to the non-display surface of the display panel 101 via a connecting layer 104. Optionally, the connecting layer 104 can be an adhesive layer. That is, the non-display surface of the display panel 101 is bonded to the protective layer 102 via the adhesive layer to ensure the reliability of the connection between the display panel 101 and the protective layer 102. Furthermore, after the non-display surface of the display panel 101 is connected to the side of the protective layer 102 with the second hole 102b via the connecting layer 104, the display panel 101, the protective layer 102, and the connector 103 can form a whole, resulting in the display module 10.

[0110] In summary, this application provides a method for manufacturing a display module. The display panel in the display module prepared by this method has an irregular shape, and the protective layer connected to the non-display surface of the display panel also has an irregular shape. Therefore, this protective layer can protect the non-display surface of the display panel, making it less susceptible to damage.

[0111] Figure 9 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. (Reference) Figure 9 The display device may include a power supply component 20 and a display module 10 as provided in the above embodiments, which is connected to the power supply component 20. The power supply component 20 can be used to supply power to the display module 10.

[0112] Optionally, the display device may further include a housing (not shown in the figure). This housing can be connected to the connector 103 in the display module 10. For example, if the connector 103 in the display module 10 is... Figures 4 to 6 For any of the connectors shown, the housing may have a corresponding hole.
