[0028] The exemplary embodiments disclosed in the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0029] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0030] At present, from the development of the market situation, it can be known that the application field of electronic technology is expanding day by day. As the parts in electronic equipment become more and more sophisticated, the structure used to protect precision parts from damage is gradually receiving attention. Among them, the "pressing strip" used in electronic equipment to protect the display module from bumps or bumps is also called a buffer strip, shockproof strip, protective strip, etc. It is a physical protective component. Its main function is to reduce the mechanical shock and vibration damage to the fragile display module during the equipment assembly process and daily use. This press strip is usually designed to be installed between the display screen and the shell or other hard structure to form a buffer layer. When the device is subjected to external pressure or falling impact, the press strip can absorb and disperse the force, thereby avoiding direct transmission to the fragile LCD panel or touch screen, causing damage to internal components or screen rupture. For example, in mobile electronic devices such as laptops, tablets, and smart phones, such protective press strips are often set around the display module to ensure that the risk of damage to the display component can be greatly reduced when the device is transported, carried, or even accidentally dropped.

[0031] The inventors of this application discovered that the pressure strip design on the electronic device also leads to some technical defects. For example, the pressure strip increases the border size of the device, causing design difficulties for the appearance structure of the electronic device. The connection structure between the screen of the electronic device and the pressure strip also has reliability issues. Although it can protect the side of the screen, the connection structure may break and fall off due to external force impact such as falling. Moreover, collision between the pressure strip and the screen after it falls off is one of the common problems that damage the screen structure.

[0032] The technical problem to be solved by the present application is to eliminate the pressure strip component and add a protective structure formed by extending the screen substrate layer in the display module to solve the reliability problem of the split pressure strip component on the display module. Therefore, the following embodiments are proposed:

[0033] Reference Figures 1 to 4 As shown, the present application provides a display module, which mainly includes: a first functional layer 1, composed of a plurality of display units, the first functional layer 1 enables the display module to have a display function through the plurality of display units, the first functional layer 1 has a first surface and a second surface adjacent to the first surface; wherein the first surface is a surface formed by arranging the plurality of display units; a second functional layer 2, composed of a first part 21 and a second part 22, the first part 21 is bonded to the first surface for supporting the plurality of display units; the second part 22 is connected to the first part 21 and covers the second surface.

[0034] Specifically, in the technical solution adopted in the present application, the first functional layer 1 is composed of several layers, which are responsible for making the display module have a display function. The first functional layer 1 may include a backplane, a light-emitting layer, a touch-sensitive layer, a circular polarizer layer, and a screen protection layer. The functional layers are stacked to form a first surface facing the middle frame and various second surfaces adjacent to the first surface on the first functional layer 1. It can be understood that the second surface is the surface of the first functional layer 1 facing the second part 22, which has functions such as displaying images and optimizing image quality. The second functional layer 2 is used to support the first functional layer 1 on the middle frame 4, and is also referred to as a substrate layer. In the present application, the material of the substrate layer can be selected from The second functional layer 2 is a plastic flexible material, so that the second part 22 can be formed by the processing technology later; the first part 21 of the second functional layer 2 is supported between the first surface and the middle frame 4, which can play a vital basic support and functional role; specifically, the substrate layer is the physical infrastructure of the entire display module, which can provide a flat and solid carrier for thin film transistors (TFT), organic light emitting diodes (OLED), liquid crystal materials (LCD) or other display materials, ensuring that the deposition, photolithography, etching and other steps of each layer of thin film in the subsequent manufacturing process can be carried out smoothly, and for display products that require thinness, shock resistance or bendability, the substrate can be selected from materials with certain mechanical strength and flexibility. In one embodiment of the present application, the second part 22 of the second functional layer 2 is structurally deformed by the bending process, and is covered on the second surface of the first functional layer 1 respectively.

[0035] After adopting the above structure, the pressure strip component in the display module can be replaced, making the external structure of the display module simpler, which can double its sense of luxury, and can also make the electronic device have a more open design concept in appearance without being constrained by the pressure strip component.

[0036] For further reference, Figure 1 As shown, in some embodiments, the first portion 21 and the second portion 22 are integrally formed to form the second functional layer 2 .

[0037] Specifically, in the technical solution adopted by the present application, the second part 22 is an extension of the second functional layer 2, so the second part 22 and the first part 21 are integrally formed, and both belong to a part of the structure of the second functional layer 2. The second part 22 is used to protect the various functional layers in the display module from being damaged to a certain extent. Since the second part 22 and the second functional layer 2 are in an integrally formed connection structure, the reliability of the connection structure between the protection structure and the display module is significantly enhanced, and the electronic device using the display module of the present application can also be subjected to external pressure or falling impact, and the probability of damaging the display module due to the detachment of the protection structure can also be reduced.

[0038] For further reference, Figure 1 and Figure 3 As shown, in some embodiments, the extension direction of the second portion 22 is parallel to the second surface, so that the second portion 22 can completely cover the second surface.

[0039] For further reference, Figure 2 and Figure 4 As shown, in some embodiments, it also includes: a connecting layer 3 filled between the second part 22 and the first functional layer 1 , and the second part 22 is fixedly connected to the first functional layer 1 through the connecting layer 3 .

[0040] Specifically, in the technical solution adopted in the present application, the connecting layer 3 can be composed of a special caulking glue in the display module, and the caulking glue is poured into the gap between the second part 22 and the first functional layer 1 until the caulking glue solidifies to form the connecting layer 3, so that the connecting layer 3 can connect the first part 21 to the first functional layer 1, and when the second functional layer 2 adopts a bending process, the extension direction of the second part 22 can be set to be parallel to the second surface by bending, so that the gap between the second part 22 and the first functional layer 1 can achieve an effect of equal width, and the connecting layer 3 formed after the caulking glue is poured into the gap can also be more uniform, so that the strength of the connection structure between the second part 22 and the first functional layer 1 is more balanced and stable.

[0041] For further reference, Figure 3 and Figure 4 As shown, in some embodiments, the second functional layer 2 further includes: a third portion 23 connected to the second portion 22; the extension direction of the third portion 23 is parallel to the first surface, and the third portion 23 is located on the side of the first functional layer 1 away from the first surface.

[0042] refer to Figure 4 As shown, in some embodiments, it also includes: a connecting layer 3, which includes a first connecting portion 31 and a second connecting portion 32, the first connecting portion 31 is arranged in the gap between the second portion 22 and the first functional layer 1, and the second connecting portion 32 is arranged in the gap between the third portion 23 and the first functional layer 1; the second portion 22 is fixedly connected to the second surface through the first connecting portion 31; the third portion is overlapped on the third surface of the first functional layer 1 away from the first surface through the second connecting portion 32.

[0043] Specifically, in the technical solution adopted by the present application, the second part 22 is further formed into the third part 23 on the outer edge away from the first part 21 through a bending process, specifically, the outer end of the second part 22 is bent inward to form the third part 23. It should be noted that since the first functional layer 1 needs to be supported by the second functional layer 2, that is, the first functional layer 1 is installed in the installation groove formed by the first part 21 and the second part 22, if the second part 22 is bent to form the third part 23 before the first functional layer 1 is installed, it will form an obstacle in the process of installing the first functional layer 1. Therefore, the present application can perform the operation of forming the third part 23 by bending after the first functional layer 1 is installed on the second functional layer 2. In one embodiment, the third part 23 formed by bending is parallel to the first functional layer 1, specifically, parallel to the third surface of the first functional layer 1 facing away from the first surface, so that a gap of equal width or thickness is formed between the third part 23 and the first functional layer 1. Preferably, the gap between the third part 23 and the first functional layer 1 and the gap between the second part 22 and the first functional layer 1 can be made the same size, so that after the gap is filled with a caulking glue that can connect the second part 22 and the third part 23 to the first functional layer 1, the first connecting part 31 and the second connecting part 32 formed after the caulking glue solidifies have the same thickness, so that the connection strength between the second part 22 and the third part 23 and the first functional layer 1 is similar, so that the buffering effect of the second part 22 and the third part 23 of the second functional layer 2 can be more balanced.

[0044] Furthermore, in some embodiments, the second functional layer 2 is made of stainless steel, titanium alloy or carbon fiber.

[0045] Specifically, in the technical solution adopted in the present application, the advantage of using stainless steel material is that it has good mechanical strength and hardness, which can ensure the stability and durability of the substrate during the assembly process, and also has excellent corrosion resistance, especially in humid or chemically polluted environments. It can effectively protect internal electronic components from corrosion, and stainless steel is easy to form and process, and is suitable for large-scale production.

[0046] The advantage of using titanium alloy is that it has a very high strength-to-weight ratio, which means it can provide sufficient strength while remaining lightweight, which is critical for mobile devices that need to reduce the overall weight of the device. Titanium alloy has excellent heat and cold resistance, suitable for applications in extreme temperature environments, and also has excellent corrosion resistance, making it less prone to damage after long-term use.

[0047] The advantages of using carbon fiber composite materials are their very low density and extremely high strength, which are particularly suitable for the design of high-end electronic products that require thinness and weight reduction. They also have excellent rigidity, which can improve the overall structural stability of the display module and reduce the degradation of the display effect caused by deformation due to stress. Compared with other materials, carbon fiber composite materials have excellent fatigue resistance and can still maintain good mechanical properties after long-term use, reducing the risk of failure under long-term stress.

[0048] Furthermore, in some embodiments, the first functional layer 1 includes a first region, a second region, and a third region, the first region and the third region are connected through the second region, and the second region is bendable; the second portion 22 circumferentially covers the second surface of the first functional layer 1, and the second portion 22 has a gap, and the gap corresponds to the second surface on the second region.

[0049] Specifically, in the technical solution adopted by the present application, the second area can correspond to the folding part on the display module, so that the first functional layer 1 can cooperate with the display module to be folded and transformed into a usage form. In order to make the second part 22 of the second functional layer 2 wrapped by the first functional layer 1 also adapt to the display device with a folding function, in the embodiment of the present application, a gap corresponding to the second area is provided on the second part 22, so that when the second functional layer 2 follows the first functional layer 1 to be folded, the second part 22 on the second functional layer 2 can make way through the gap, so that during the folding process of the second functional layer 2, the structure of the second part 22 will not form a structural conflict. In one embodiment, a plurality of gaps can also be opened to form a complementary structure with the second part 22 corresponding to the second area, so that during the folding process, the second part 22 can seal the gaps between each other, so that the second part 22 will not form a structural conflict during the folding process to hinder the completion of the folding operation.

[0050] Furthermore, in some embodiments, each side edge of the first portion 21 is connected to a second portion 22 , respectively, and each second portion 22 is bent and covered on the corresponding second surface of the first functional layer 1 in a splicing manner.

[0051] Specifically, in the technical solution adopted in the present application, each functional layer of the display module has a plurality of straight side edges, and the second part 22 is formed by extending the straight side edges on the second functional layer 2, and when each second part 22 reaches the desired structural deformation through a bending process, two adjacent second parts 22 can be spliced ​​above the first part 21 to form an assembly position for installing the first functional layer 1, and each second part 22 can cover the second surface of the first functional layer 1 to achieve a protective effect.

[0052] The present application also proposes an electronic device, which mainly comprises: a middle frame 4 for connecting a display module and a back cover, and a first functional layer 1 and a second functional layer 2 capable of being attached to the middle frame 4;

[0053] The first functional layer 1 is composed of multiple display units. The first functional layer 1 enables the display module to have a display function through the multiple display units. The first functional layer 1 has a first surface and a second surface adjacent to the first surface; wherein the first surface is a surface formed by the arrangement of multiple display units; the second functional layer 2 is composed of a first part 21 and a second part 22, the first part 21 is bonded to the first surface and is used to support the multiple display units; the second part 22 is connected to the first part 21 and covers the second surface.

[0054] Specifically, in the technical solution adopted in the present application, the electronic device mainly adopts the display module in the above-mentioned embodiment, by extending the structure of the second functional layer 2 and deforming its structure through a bending process, so that the second part 22 of the second functional layer 2 replaces the pressure strip component to cover the second surface of the first functional layer 1, thereby achieving the effect of protecting the first functional layer 1.

[0055] After the above-mentioned technical solution is adopted in the present application, not only can the display module be freed from the structural constraints of the pressure strip component, but also the reliability problems of the connection structure between the split pressure strip component and the display module or the electronic device can be avoided. At the same time, the strength of the protective structure can also be improved, and the probability of damage to the display module due to breakage of the protective structure after being subjected to external pressure or falling impact can be effectively reduced.

[0056] In some embodiments, the above-mentioned electronic device may be a device with a folding function, which mainly includes a first body and a second body connected to each other in a flipping manner, and the electronic device with a folding function is equipped with the display module in the present application, and the first area of ​​the first functional layer in the display module is located on the first body, and the third area is located on the second body. The technical point of the electronic device is that the second area is arranged between the first body and the second body, so that the second area corresponds to the folding part of the electronic device. When the second part of the second functional layer in the embodiment of the above-mentioned display module has a gap, the gap also corresponds to the folding part of the electronic device, so that when the electronic device is folded, the second part of the second functional layer can make way through the gap. While protecting the first functional layer through the second functional layer, the second functional layer structure to be protected can also cooperate with the electronic device to complete the folding operation, thereby avoiding structural conflicts between the second part structures located in the first area and the third area.

[0057] In some embodiments, the electronic device may be a flexible display module equipped with a bending function, and the flexible display module may also adopt a method of protecting the display function through a substrate layer. The specific implementation method may refer to the above embodiment, and the difference between this embodiment and the above embodiment is that a plurality of sparse gaps are arranged on the second part of the second functional layer to form a protective structure array on the second part that can cooperate with the bending of the electronic device. When in use, the second part on the second functional layer can complete the bending operation through the cooperation of the corresponding plurality of gaps, so that the protective structure array will not be hindered by structural conflicts caused by the bending of the display module.
