[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0035] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] At present, when assembling the case of a display screen using the full-bonding process, the case and the cover plate need to be connected. However, when the case is connected, stress will inevitably be applied to the cover plate, and these stresses will be subsequently transmitted to the liquid crystal display module (LCM) through the optical adhesive, causing the liquid crystal of the display screen to be compressed or squeezed in a local position, making the arrangement of the liquid crystal molecules disordered, thereby aggravating light leakage and yellow spots, affecting the display effect, resulting in low overall production yield and high scrap rate, which not only affects the appearance and performance of the product, but also increases production costs.

[0040] Therefore, the present application provides a display device that can absorb and buffer the stress transmitted to the liquid crystal display module, so that the liquid crystal of the display screen is not easily compressed or squeezed when the casing is assembled, thereby solving the light leakage and yellow spot problems and ensuring the display effect and production cost.

[0041] See also Figure 1 and Figure 2 An embodiment of the present application provides a display device, including a display mechanism 1 and a stress absorption mechanism 2. The display mechanism 1 includes a cover plate 11 and a display component 12. The display component 12 has a polarizer 13 on the side facing the cover plate 11. The stress absorption mechanism 2 is arranged between the cover plate 11 and the polarizer 13 along the thickness direction, so that the stress absorption mechanism 2 can absorb and buffer the stress transmitted to the display component 12, thereby preventing light leakage and yellow spot phenomenon, and ensuring the display effect and production cost.

[0042] Specifically, the stress absorbing mechanism 2 includes a first adhesive layer 21, a second adhesive layer 22 and a stress absorbing plate 23, and the stress absorbing plate 23 is arranged between the first adhesive layer 21 and the second adhesive layer 22 along the thickness direction. More specifically, the first adhesive layer 21 is arranged on the side of the display component 12 facing the cover plate 11, the second adhesive layer 22 is arranged on the side of the cover plate 11 facing the display component 12, and the two side surfaces of the absorbing plate along the thickness direction are connected to the first adhesive layer 21 and the second adhesive layer 22 respectively.

[0043] When the cover plate 11 is subjected to stress, the stress can be transmitted to the display component 12 through the second adhesive layer 22, the stress absorbing plate 23 and the first adhesive layer 21 in sequence. During the transmission process, the stress is gradually absorbed by the second adhesive layer 22, the stress absorbing plate 23 and the first adhesive layer 21, so that the display component 12 will not be compressed or squeezed due to the stress, thereby ensuring the display effect.

[0044] In summary, the display device of the present application, by arranging a stress absorbing mechanism 2 between the cover plate 11 and the display component 12, enables the stress absorbing mechanism 2 to absorb and buffer the stress applied to the display component 12 by the cover plate 11 during assembly, so that the display component 12 is not easily compressed or squeezed at a local position to cause light leakage and yellow spot phenomenon, thereby ensuring the display effect and production yield. At the same time, by making the stress absorbing mechanism 2 have a stress absorbing plate 23 with a plate-like structure, it is ensured that the stress absorbing mechanism 2 has a larger contact area with the cover plate 11 and the display component 12, further ensuring the protection effect of the display component 12, so as to ensure the appearance and performance of the product while ensuring the production cost.

[0045] See also Figure 1 and Figure 2 In one embodiment, the first adhesive layer 21 is a transparent adhesive layer, and the second adhesive layer 22 is a transparent adhesive layer. The transparent adhesive layer can effectively buffer the external force and avoid the problem of damage to the display component 12 caused by the external force, while ensuring high light transmittance, reducing reflection and improving display effect.

[0046] Specifically, the first adhesive layer 21 is an optically transparent adhesive (OCA) or a liquid optically transparent adhesive (LOCA), so as to ensure the adhesive effect between the cover plate 11 and the stress absorbing plate 23, while ensuring high light transmittance, reducing reflection and improving display effect. The second adhesive layer 22 is an optically transparent adhesive (OCA) or a liquid optically transparent adhesive (LOCA), so as to ensure the adhesive effect between the display component 12 and the stress absorbing plate 23, while ensuring high light transmittance, reducing reflection and improving display effect.

[0047] In summary, when the cover plate 11 applies stress to the stress absorbing mechanism 2, the second adhesive layer 22 is deformed to buffer the stress. At the same time, due to the presence of the stress absorbing plate 23, the stress can be effectively dispersed to reduce the occurrence of deformation. Finally, it cooperates with the first adhesive layer 21 to enhance the strength and toughness of the display component 12, reduce the impact of stress on the display component 12, and make the display component 12 less prone to light leakage and yellow spots due to compression or extrusion at local positions, thereby ensuring the display effect and production yield.

[0048] In one embodiment, the stress absorbing plate 23 is a hard plate. The high strength and high rigidity of the hard plate can effectively disperse the stress on the stress absorbing plate 23, thereby avoiding the light leakage and yellow spot phenomenon caused by compression or extrusion of the display component 12 at a local position, thereby ensuring the display effect and production yield. That is, after the second adhesive layer 22 transfers the stress to the stress absorbing plate 23, since the stress absorbing plate 23 is a hard plate, the stress absorbing plate 23 will not be deformed, and the stress can be uniformly applied to the first adhesive layer 21. The first adhesive layer 21 acts as the last step of buffering, so that the display component 12 will not leak light and yellow spot due to compression or extrusion at a local position, thereby ensuring the display effect and production yield. It can be understood that the hard plate is a material with high hardness, high strength and good wear resistance, and is usually used in application scenarios that need to withstand large mechanical stress or wear. According to different material compositions and application scenarios, hard plates can be divided into various types, such as carbide plates, hard fiberboards, hard circuit boards, etc.

[0049] Specifically, in the embodiment of the present application, the stress absorbing plate 23 is a glass plate, which can evenly apply stress to the first adhesive layer 21 through its high strength and high rigidity, so that the display component 12 will not leak light and produce yellow spots due to compression or extrusion at a local position, and can also ensure high light transmittance, reduce reflection and improve display effect through its transparent characteristics. That is, in the embodiment of the present application, the hardness range of the hard plate is between 5 and 7 on the Mohs hardness scale.

[0050] In addition, in the embodiments of the present application, the glass plate may be a single-layer glass plate or a multi-layer laminated glass.

[0051] See also Figure 1and Figure 2 In one of the embodiments, the projection area of ​​the stress absorbing mechanism 2 on the cover plate 11 is less than or equal to the projection area of ​​the display component 12 on the cover plate 11, so that the stress absorbing mechanism 2 will not exceed the range of the display component 12, thereby avoiding blocking of the display area, and at the same time ensuring that the stress absorbing mechanism 2 will not interfere with the light transmission path of the display component 12, thereby ensuring the clarity and uniformity of the display effect, so that the stress absorbing mechanism 2 will not affect the display effect of the display component 12.

[0052] Specifically, the projection area of ​​the stress absorbing mechanism 2 on the cover plate 11 is equal to the projection area of ​​the display assembly 12 on the cover plate 11. By reasonably designing the projection area of ​​the stress absorbing mechanism 2, the fitting area between the cover plate 11 and the display assembly 12 can be optimized, and the poor fitting caused by the excessive size of the stress absorbing mechanism 2 can be reduced. While ensuring the protective effect of the stress absorbing mechanism 2 on the display assembly 12, the stress absorbing mechanism 2 will not affect the display effect of the display assembly 12.

[0053] It can be understood that the projected area of ​​the stress absorbing mechanism 2 on the cover plate 11 is the product of the length and width of the stress absorbing mechanism 2, and the projected area of ​​the display assembly 12 on the cover plate 11 is the product of the length and width of the display assembly 12. In the embodiment of the present application, the length of the stress absorbing mechanism 2 is less than or equal to the length of the display assembly 12, and the width of the stress absorbing mechanism 2 is less than or equal to the width of the display assembly 12. Further, the length of the stress absorbing mechanism 2 is equal to the length of the display assembly 12, and the width of the stress absorbing mechanism 2 is equal to the width of the display assembly 12.

[0054] In one embodiment, the projected area of ​​the stress absorbing plate 23 on the cover plate 11 is consistent with the projected area of ​​the second adhesive layer 22 on the cover plate 11, so that the stress absorbing plate 23 can completely receive the stress from the second adhesive layer 22. The projected area of ​​the stress absorbing plate 23 on the cover plate 11 is consistent with the projected area of ​​the first adhesive layer 21 on the cover plate 11, so that the stress on the stress absorbing plate 23 can completely act on the first adhesive layer 21, thereby ensuring that the display component 12 will not cause light leakage and yellow spot phenomenon due to compression or extrusion at a local position, thereby ensuring the display effect and production yield.

[0055] It can be understood that the projected area of ​​the first adhesive layer 21 of the stress absorbing plate 23 on the cover plate 11 is the product of the length and width of the stress absorbing plate 23, the projected area of ​​the first adhesive layer 21 on the cover plate 11 is the product of the length and width of the first adhesive layer 21, and the projected area of ​​the second adhesive layer 22 on the cover plate 11 is the product of the length and width of the second adhesive layer 22. In the embodiment of the present application, the length of the stress absorbing plate 23 is equal to the length of the first adhesive layer 21, the width of the stress absorbing plate 23 is equal to the width of the first adhesive layer 21, the length of the second adhesive layer 22 is equal to the length of the first adhesive layer 21, and the width of the second adhesive layer 22 is equal to the width of the first adhesive layer 21.

[0056] See also Figure 1 and Figure 2 In one embodiment, the thickness of the stress absorbing mechanism 2 is proportional to the projected area of ​​the display component 12 on the cover plate 11, so as to effectively ensure the stress absorption capacity and ensure that the display component 12 will not leak light and produce yellow spots due to compression or extrusion at a local position, thereby ensuring the display effect and production yield. It can be understood that a thicker stress absorbing mechanism 2 can provide a larger deformation space, so that the stress can be more effectively absorbed and dispersed, so as to effectively protect the display component 12 with a larger surface area.

[0057] Specifically, in the embodiment of the present application, the thickness of the first adhesive layer 21 is greater than or equal to 0.25 mm and less than or equal to 0.5 mm, the thickness of the second adhesive layer 22 is greater than or equal to 0.25 mm and less than or equal to 0.5 mm, and the thickness of the stress absorption plate 23 is greater than or equal to 0.2 mm and less than or equal to 0.7 mm.

[0058] See also Figure 1 In one embodiment, the display mechanism 1 also includes a housing 14, which is disposed on the cover plate 11 and cooperates with the cover plate 11 to form an installation space, and the stress absorption mechanism 2 and the display component 12 are both disposed in the installation space, so that the display device of the present application is a common backlight structure.

[0059] Specifically, the display assembly 12 includes a backlight module 122 and a display module 121 having a liquid crystal panel, and the backlight module 122 and the display module 121 are assembled simultaneously during the production process to form a whole. This design can make the entire display assembly 12 more compact and suitable for devices with high space requirements.

[0060] See also Figure 3 In one embodiment, the display assembly 12 includes a display module 121 and a backlight module 122. The backlight module 122 is arranged on the cover plate 11 and cooperates with the cover plate 11 to form an installation space. The stress absorption mechanism 2 and the display module 121 are both arranged in the installation space, so that the display device of the present application is a post-assembly backlight structure.

[0061] Specifically, the display module 121 has a liquid crystal panel, and the backlight module 122 is an independent component that is installed after the liquid crystal panel is assembled. This design allows the backlight module 122 to be independently produced during the production process, reducing the complexity of the liquid crystal panel assembly process. In addition, as an independent component, the backlight module 122 is easy to repair or replace when necessary, which improves the maintainability of the product.

[0062] See also Figure 4 , an embodiment of the present application further provides a method for assembling a display device, comprising:

[0063] The display component 12 is obtained, and a first adhesive layer 21 is disposed on a surface of the display component 12 having the polarizer 13 .

[0064] A stress absorbing plate 23 is obtained, and the stress absorbing plate 23 is pasted on the first pasting layer 21 .

[0065] The cover plate 11 is obtained, and a second adhesive layer 22 is disposed on the cover plate 11 .

[0066] The second adhesive layer 22 is adhered to the side of the stress absorbing plate 23 facing away from the first adhesive layer 21 .

[0067] When the cover plate 11 is subjected to stress, the stress can be transmitted to the display component 12 through the second adhesive layer 22, the stress absorbing plate 23 and the first adhesive layer 21 in sequence. During the transmission process, the stress is gradually absorbed by the second adhesive layer 22, the stress absorbing plate 23 and the first adhesive layer 21, so that the display component 12 will not be compressed or squeezed due to the stress, thereby ensuring the display effect.

[0068] In summary, the assembly method of the display device of the present application is to set a first adhesive layer 21 on the side of the display component 12 having the polarizer 13, set a second adhesive layer 22 on the cover plate 11, and stick the stress absorption plate 23 between the first adhesive layer 21 and the second adhesive layer 22, so that the stress absorption plate 23 can cooperate with the first adhesive layer 21 and the second adhesive layer 22 to absorb and buffer the stress applied to the display component 12 by the cover plate 11 during assembly, so that the display component 12 is not prone to light leakage and yellow spot phenomenon due to compression or extrusion at a local position, thereby ensuring the display effect and production yield. At the same time, the stress absorption plate 23 with a plate-like structure can ensure that the stress absorption mechanism 2 has a larger contact area with the cover plate 11 and the display component 12, further ensuring the protection effect of the display component 12, so as to ensure the appearance and performance of the product while ensuring the production cost.

[0069] In one embodiment, the stress absorbing plate 23 is a glass plate, so that the stress absorbing plate 23 has both high strength and high rigidity and high light transmittance. Among them, the stress absorbing plate 23 has high strength and high rigidity, so that the stress absorbing plate 23 can effectively disperse the stress, thereby avoiding the display component 12 from leaking light and yellow spots due to compression or extrusion at a local position, thereby ensuring the display effect and production yield. That is, after the first adhesive layer 21 transfers the stress to the stress absorbing plate 23, since the stress absorbing plate 23 is a hard plate, the stress absorbing plate 23 will not be deformed, and the stress can be uniformly applied to the second adhesive layer 22. The second adhesive layer 22 acts as the last step of buffering, so that the display component 12 will not leak light and yellow spots due to compression or extrusion at a local position, thereby ensuring the display effect and production yield. At the same time, since the display component 12 requires high light transmittance to ensure that the image is clear, bright and colorful, the high light transmittance of the stress absorbing plate 23 can effectively ensure high light transmittance, reduce reflection and improve the display effect.

[0070] In one embodiment, the first adhesive layer 21 is a transparent adhesive layer, and the second adhesive layer 22 is a transparent adhesive layer. The transparent adhesive layer can effectively buffer the external force to avoid the problem of damage to the display component 12 caused by the external force, and at the same time ensure high light transmittance, reduce reflection and improve display effect.

[0071] Specifically, the first adhesive layer 21 is an optically transparent adhesive (OCA) or a liquid optically transparent adhesive (LOCA), so as to ensure the adhesive effect between the cover plate 11 and the stress absorbing plate 23, while ensuring high light transmittance, reducing reflection and improving display effect. The second adhesive layer 22 is an optically transparent adhesive (OCA) or a liquid optically transparent adhesive (LOCA), so as to ensure the adhesive effect between the display component 12 and the stress absorbing plate 23, while ensuring high light transmittance, reducing reflection and improving display effect.

[0072] In summary, when the cover plate 11 applies stress to the stress absorbing mechanism 2, the first adhesive layer 21 is deformed to buffer the stress. At the same time, due to the presence of the stress absorbing plate 23, the stress can be effectively dispersed to reduce the occurrence of deformation. Finally, it cooperates with the second adhesive layer 22 to enhance the strength and toughness of the display component 12, reduce the impact of stress on the display component 12, and make the display component 12 less likely to cause light leakage and yellow spots due to compression or extrusion at a local position, thereby ensuring the display effect and production yield.

[0073] See also Figure 1 and Figure 2In one of the embodiments, the projection area of ​​the stress absorbing mechanism 2 on the cover plate 11 is less than or equal to the projection area of ​​the display component 12 on the cover plate 11, so that the stress absorbing mechanism 2 will not exceed the range of the display component 12, thereby avoiding blocking of the display area, and at the same time ensuring that the stress absorbing mechanism 2 will not interfere with the light transmission path of the display component 12, thereby ensuring the clarity and uniformity of the display effect, so that the stress absorbing mechanism 2 will not affect the display effect of the display component 12.

[0074] Specifically, the projection area of ​​the stress absorbing mechanism 2 on the cover plate 11 is equal to the projection area of ​​the display assembly 12 on the cover plate 11. By reasonably designing the projection area of ​​the stress absorbing mechanism 2, the fitting area between the cover plate 11 and the display assembly 12 can be optimized, and the poor fitting caused by the excessive size of the stress absorbing mechanism 2 can be reduced. While ensuring the protective effect of the stress absorbing mechanism 2 on the display assembly 12, the stress absorbing mechanism 2 will not affect the display effect of the display assembly 12.

[0075] It can be understood that the projected area of ​​the stress absorbing mechanism 2 on the cover plate 11 is the product of the length and width of the stress absorbing mechanism 2, and the projected area of ​​the display assembly 12 on the cover plate 11 is the product of the length and width of the display assembly 12. In the embodiment of the present application, the length of the stress absorbing mechanism 2 is less than or equal to the length of the display assembly 12, and the width of the stress absorbing mechanism 2 is less than or equal to the width of the display assembly 12. Further, the length of the stress absorbing mechanism 2 is equal to the length of the display assembly 12, and the width of the stress absorbing mechanism 2 is equal to the width of the display assembly 12.

[0076] In one embodiment, the projected area of ​​the stress absorbing plate 23 on the cover plate 11 is consistent with the projected area of ​​the first adhesive layer 21 on the cover plate 11, so that the stress absorbing plate 23 can completely receive the stress from the first adhesive layer 21. The projected area of ​​the stress absorbing plate 23 on the cover plate 11 is consistent with the projected area of ​​the second adhesive layer 22 on the cover plate 11, so that the stress on the stress absorbing plate 23 can completely act on the second adhesive layer 22, thereby ensuring that the display component 12 will not cause light leakage and yellow spots due to compression or extrusion at a local position, thereby ensuring the display effect and production yield.

[0077] It can be understood that the projected area of ​​the first adhesive layer 21 of the stress absorbing plate 23 on the cover plate 11 is the product of the length and width of the stress absorbing plate 23, the projected area of ​​the first adhesive layer 21 on the cover plate 11 is the product of the length and width of the first adhesive layer 21, and the projected area of ​​the second adhesive layer 22 on the cover plate 11 is the product of the length and width of the second adhesive layer 22. In the embodiment of the present application, the length of the stress absorbing plate 23 is equal to the length of the first adhesive layer 21, the width of the stress absorbing plate 23 is equal to the width of the first adhesive layer 21, the length of the second adhesive layer 22 is equal to the length of the first adhesive layer 21, and the width of the second adhesive layer 22 is equal to the width of the first adhesive layer 21.

[0078] In one embodiment, the thickness of the stress absorbing mechanism 2 is proportional to the projected area of ​​the display component 12 on the cover plate 11, so as to effectively ensure the stress absorption capacity, ensure that the display component 12 will not leak light and produce yellow spots due to compression or extrusion at a local position, and thus ensure the display effect and production yield. It can be understood that a thicker stress absorbing mechanism 2 can provide a larger deformation space, so that the stress can be more effectively absorbed and dispersed, so as to effectively protect the display component 12 with a larger surface area.

[0079] Specifically, in the embodiment of the present application, the thickness of the first adhesive layer 21 is greater than or equal to 0.25 mm and less than or equal to 0.5 mm, the thickness of the second adhesive layer 22 is greater than or equal to 0.25 mm and less than or equal to 0.5 mm, and the thickness of the stress absorption plate 23 is greater than or equal to 0.2 mm and less than or equal to 0.7 mm.

[0080] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
