Furthermore, since the display panel is set in the receiving groove, a flexible heat-conducting component is filled between the surface of the metal heat-conducting plate facing the cover plate and the first surface of the display panel.

This avoids display defects such as orange peel texture in the display module and improves the display effect of the display module. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] It should be understood that the phrase "an embodiment" or "one embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in one embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0048] Firstly, embodiments of this application provide a display module. Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of this application. Figure 2 This application provides a display module in an embodiment where... Figure 1 A magnified view of a portion of point A, as shown below. Figure 1 andFigure 2 As shown, the display module includes: a display panel 1, a cover plate 2, a metal heat-conducting plate 3, and a flexible heat-conducting component 4; the metal heat-conducting plate 3 is bent to form a receiving groove; the cover plate 2 covers the opening of the receiving groove, and the display panel 1 is disposed in the receiving groove; the two opposite ends of the metal heat-conducting plate 3 form a first heat-conducting part 31, and the middle part of the metal heat-conducting plate 3 forms a second heat-conducting part 32; the flexible heat-conducting component 4 is disposed between the second heat-conducting part 32 and the display panel 1, and the first heat-conducting part 31 is connected to the edge of the cover plate 2.

[0049] The metal heat-conducting plate 3 is mainly used to transfer heat from the display panel 1. To meet this requirement, in this embodiment, the metal heat-conducting plate 3 is bent to form a groove-shaped structure. Two sections of the metal heat-conducting plate 3 are formed on both sides of the bend, and a receiving groove is formed between the bend and the two sections of the metal heat-conducting plate 3. This receiving groove is an open-top structure. In this way, the metal heat-conducting plate 3 has sufficient space to accommodate the display panel 1 and has a connecting part that can be connected to the cover plate 2.

[0050] Specifically, in this embodiment, the cover plate 2 covers the opening of the receiving groove, and the edge of the cover plate 2 is connected to the surface of the metal heat-conducting plate 3 facing each other. This avoids the metal heat-conducting plate 3 from connecting with the display panel 1 and affecting the display effect of the display panel 1. Furthermore, it effectively conducts the charge on the surface of the glass cover plate 2 to the metal heat-conducting plate 3, reducing the risk of display defects such as greening of the display module. It should be noted that the cover plate 2 is mainly used to protect the display panel 1 and to allow light to pass through. The cover plate 2 should have thermal and chemical stability. If it is necessary to control the overall weight of the display module, the thickness and density of the cover plate 2 can be appropriately reduced. The cover plate 2 can be a transparent glass cover plate 2, an acrylic sheet, or a cover plate 2 made of other materials; this embodiment does not limit this.

[0051] A display panel 1 can be placed in the receiving groove formed by bending the metal heat-conducting plate 3, so that the first surface of the display panel 1 and the bottom of the receiving groove are facing each other. By filling the space between the surface of the metal heat-conducting plate 3 facing the cover plate 2 and the first surface of the display panel 1, the surface of the metal heat-conducting plate 3 facing the cover plate 2 and the first surface of the display panel 1 will not directly contact each other. In this way, the flexible heat-conducting component 4 can not only increase the heat dissipation capacity of the module, but also avoid stress on the first surface of the display panel 1 by the metal heat-conducting plate 3 due to the elasticity of the flexible heat-conducting component 4. This avoids display defects such as orange peel texture in the display module and improves the display effect of the display module.

[0052] In some embodiments, the orthographic projection area of ​​the display panel 1 on the cover plate 2 is smaller than the area of ​​the cover plate, and the distance between the edge of the orthographic projection of the display panel 1 on the cover plate 2 and the edge of the cover plate 2 is greater than or equal to 2.5 mm.

[0053] It should be noted that when the orthographic projection area of ​​the display panel 1 on the cover plate 2 is smaller than the area of ​​the cover plate, and the distance between the edge of the orthographic projection of the display panel 1 on the cover plate 2 and the edge of the cover plate 2 is greater than or equal to 2.5 mm, the cover plate 2 can be set to extend beyond the display panel 1. In this way, the cover plate 2 can be guaranteed to have sufficient size to fix the metal heat-conducting plate 3, thus creating conditions for fixing the metal heat-conducting plate 3 and the cover plate 2.

[0054] In addition, it should be noted that the thickness of the metal heat-conducting plate 3 can be less than 0.5 mm to 1 mm. In this way, while ensuring that the metal heat-conducting plate 3 has a certain strength, it will not take up too much space in the display module and facilitates the lightweight design of the display module.

[0055] As can be seen from the above embodiments, in this application embodiment, the metal heat-conducting plate 3 is bent to form a receiving groove, the display panel 1 is placed in the receiving groove, the cover plate 2 covers the opening of the receiving groove, the two opposite ends of the metal heat-conducting plate 3 form a first heat-conducting part 31, the middle part of the metal heat-conducting plate 3 forms a second heat-conducting part 32, the flexible heat-conducting element 4 is disposed between the second heat-conducting part 32 and the display panel 1, and the first heat-conducting part 31 is connected to the edge of the cover plate 2, thus allowing the metal heat-conducting plate 3 to be directly connected to the cover plate 2. In this way, on the one hand, the connection between the metal heat-conducting plate 3 and the display panel 1 can be avoided from affecting the display effect of the display panel 1, and on the other hand, the charge on the surface of the cover plate 2 can be effectively conducted to the metal heat-conducting plate 3, reducing the risk of display defects such as greening of the display module. Furthermore, since the display panel 1 is set in the receiving groove, and a flexible heat-conducting element 4 is filled between the surface of the metal heat-conducting plate 3 facing the cover plate 2 and the first surface of the display panel 1, the flexible heat-conducting element 4 can not only increase the heat dissipation capacity of the display module, but also avoid the metal heat-conducting plate 3 from generating stress on the display panel 1 due to the elasticity and fluidity of the flexible heat-conducting element 4, thereby avoiding display defects such as orange peel texture in the display module and improving the display effect of the display module.

[0056] Furthermore, in some embodiments, the connection between the edge of the cover plate 2 and the facing surface of the metal heat-conducting plate 3 can be achieved by connecting the edge of the cover plate 2 and the first heat-conducting part 31 through conductive adhesive 5. It should be noted that the conductive adhesive 5 may include a resin matrix, conductive particles, and dispersing additives and auxiliaries. The resin matrix may include epoxy resin, acrylic resin, or polyurethane; this embodiment does not limit the specific type. Thus, the connection between the edge of the cover plate 2 and the facing surface of the metal heat-conducting plate 3 through conductive adhesive 5 avoids the metal heat-conducting plate 3 from being directly connected to the display panel 1, thus preventing any impact on the display effect of the display panel 1. Additionally, it effectively conducts the charge on the surface of the glass cover plate 2 to the metal heat-conducting plate 3, reducing the risk of display defects such as greening of the display module. Further explanation is that the aforementioned beneficial effects can be understood as follows: when the metal heat-conducting plate 3 is directly connected to the display panel 1, the surface roughness and deformation of the metal heat-conducting plate 3 will affect the flatness of the display panel 1, thereby impacting the display effect. Based on this, the edge of the cover plate 2 and the facing surface of the metal heat-conducting plate 3 are connected by conductive adhesive 5. This avoids direct connection between the metal heat-conducting plate 3 and the display panel 1, so as to ensure the display effect of the display panel 1 while satisfying the requirements of the display panel 1.

[0057] like Figure 3 and Figure 4 As shown, after filling the space between the edge of the cover plate 2 and the opposing surfaces of the metal heat-conducting plate 3 with conductive adhesive 5, the charge generated on the surface of the cover plate 2 will be transferred to the metal heat-conducting plate 3 through the conductive adhesive 5, preventing the accumulation of charge on the surface of the cover plate 2, thereby reducing the risk of display defects such as greening of the display module. Figure 3 The direction indicated by S in the diagram represents the direction of charge flow. Figure 4 The direction indicated by X in the figure represents the direction of charge transfer. It should also be noted that the conductive adhesive 5 can also contain a metal connector or other structures added to the thermally conductive adhesive; this embodiment does not limit this. For example, metal powder or metal rod-shaped structures can be filled into the thermally conductive adhesive. This allows not only the heat between the cover plates 2 to be transferred to the metal heat-conducting plate 3 through the thermally conductive adhesive, but also the charge in the cover plates 2 to be transferred to the metal connector through the metal powder or metal rod-shaped structures in the thermally conductive adhesive.

[0058] Furthermore, the conductive adhesive 5 is a conductive double-sided adhesive; the conductive double-sided adhesive includes a first adhesive surface and a second adhesive surface, the first adhesive surface is connected to the cover plate 2, and the second adhesive surface is connected to the first heat-conducting part 31. In this way, the conductive double-sided adhesive makes the connection between the cover plate 2 and the metal heat-conducting plate 3 more secure.

[0059] To allow the metal heat-conducting plate 3 to connect with the cover plate 2, in this embodiment, the two opposite ends of the metal heat-conducting plate 3 are bent relative to the middle of the metal heat-conducting plate 3, forming receiving grooves on the two sides and in the middle. For example, the metal heat-conducting plate 3 may include opposite first and second ends. The first end is bent towards the cover plate 2, and after bending, it is bent again to form a right-angled plate. Similarly, the first end is bent towards the cover plate 2, and after bending, it is bent again to form a right-angled plate. Thus, the opposite sides of the right-angled plate formed at the first end and the right-angled plate formed at the second end constitute the two walls of the receiving groove, reserving space for the display panel 1. The right-angled sides of the right-angled plate formed at the first end and the right-angled plate formed at the second end, facing the cover plate 2, can provide space for connection with the cover plate 2. This allows the metal heat-conducting plate 3 to conduct heat to the heat dissipation film layer while avoiding direct connection between the metal heat-conducting plate 3 and the display panel 1.

[0060] Furthermore, a first heat-conducting portion 31 is formed at two opposite ends of the metal heat-conducting plate 3, and a second heat-conducting portion 32 is formed in the middle of the metal heat-conducting plate 3; the first heat-conducting portion 31 is connected to the edge of the cover plate 2, and a flexible heat-conducting element 4 is provided between the second heat-conducting portion 32 and the first surface of the display panel 1. In this way, the first heat-conducting portion 31 provides a surface for connection with the cover plate 2, and the second heat-conducting portion 32 can transfer heat from the display panel 1.

[0061] Furthermore, the metal heat-conducting plate 3 also includes a third heat-conducting part 33; the first heat-conducting part 31 and the second heat-conducting part 32 are connected by the third heat-conducting part 33; the third heat-conducting part 33 intersects with the first heat-conducting part 31 and the second heat-conducting part 32 respectively, and the first heat-conducting part 31, the second heat-conducting part 32 and the third heat-conducting part 33 are bent to form a receiving groove. In this way, the receiving groove can meet the condition that the metal heat-conducting plate 3 can be directly connected to the cover plate 1.

[0062] Optionally, the distance between the first heat-conducting part 31 and the cover plate 2 is smaller than the distance between the second heat-conducting part 32 and the cover plate 2. This creates a height difference between the first heat-conducting part 31 and the second heat-conducting part 32, which forms a receiving groove. This groove provides space for the display panel 1, allowing heat dissipation through the metal heat-conducting plate 3 after the display panel 1 is placed in the receiving groove.

[0063] Optionally, the connection between the first heat-conducting part 31 and the third heat-conducting part 33, and the connection between the second heat-conducting part 32 and the third heat-conducting part 33, are arc-shaped corner structures. This prevents friction between the metal heat-conducting plate 1 and the display panel 1 at the bends when connecting the metal heat-conducting plate 1 and the cover plate 2, thus ensuring the structural integrity of the display panel 1. Figure 2As shown, the arc-shaped corner structure of the connection between the first heat-conducting part 31 and the third heat-conducting part 33 is as follows: Figure 2 As shown in N, the connection between the second heat-conducting part 32 and the third heat-conducting part 33 is an arc-shaped corner structure, as shown in the figure. Figure 2 As shown in M.

[0064] In addition, in some embodiments, the display panel 1 includes a display film layer 11, an encapsulation layer 12, and a polarizer 13; the encapsulation layer 12 is stacked on the display film layer 11, and the polarizer 13 is stacked on the encapsulation layer 12.

[0065] It should be noted that the polarizer 13 is mainly used to dissipate surface reflections of the display film layer 11 and can also scatter light to increase the viewing angle of the display module. It should also be noted that since the display film layer 11 is stacked on the flexible heat-conducting component 4, the encapsulation layer 12 is stacked on the display film layer, the polarizer is stacked on the encapsulation layer 12, and the cover plate 2 is stacked on the polarizer 13, the heat from each layer in the display panel 1 can be transferred to the metal heat-conducting plate 3, and ultimately transferred to the outside through the metal heat-conducting plate 3, thus improving the heat dissipation function of the display module.

[0066] Furthermore, the touch layer 14 is stacked on the polarizer 13;

[0067] The touch layer 14 is connected to the surface of the metal heat-conducting plate 3 via the first adhesive layer 6 and the cover plate 2, and the polarizer 13 and the touch layer 14 are connected via the second adhesive layer 7. It should be noted that the touch layer 14 is mainly used to implement the touch function of the display module. In some embodiments, the display module may not include the polarizer 13 and the touch layer 14, or the display module may include the polarizer 13 but not the touch layer 14. When the display module is applied to an application environment requiring touch control, it may include the touch layer 14; this application embodiment does not limit this. Thus, by stacking the touch layer 14 on the polarizer 13, connecting the touch layer 14 to the surface of the metal heat-conducting plate 3 via the first adhesive layer 6 and the cover plate 2, and connecting the polarizer 13 and the touch layer 14 via the second adhesive layer 7, the heat in the touch layer 14 can also be transferred to the metal heat-conducting plate 3 for dissipation.

[0068] In addition, in some optional embodiments, the flexible thermal conductive element 4 is thermally conductive silicone grease, and the first adhesive layer 6 and the second adhesive layer 7 are optical adhesives.

[0069] It should be noted that, due to the elasticity and thermoplasticity of thermal grease, when the thermal grease is located between the metal heat-conducting plate 3 and the display panel 12, it allows for installation slack in the connection between the display panel 12 and the metal heat-conducting plate 3. This facilitates installation and reduces damage to the structure of the display panel 12 or affects its flatness during assembly. Furthermore, since optical adhesive is a polymer with similar optical properties to the display panel 12 and the touch layer 14 and possesses excellent adhesive properties, when the first adhesive layer 6 and the second adhesive layer 7 are optical adhesives, the connection between the touch layer 14 and the polarizer 13, and between the touch layer 14 and the cover plate 2, is satisfied without affecting the display effect of the display panel 12.

[0070] like Figure 5 and Figure 6 As shown, further, the display panel 1 is a flexible display panel, meaning that both the first and second surfaces of the display panel 1 are curved surfaces. It should be noted that when both the first and second surfaces of the display panel 1 are curved, the entire structure of the display panel 1 becomes an arc-shaped plate structure, i.e., a curved display structure. In this structure, because the first surface of the display panel 1 is curved, when the first surface is directly connected to the metal heat-conducting plate 3, the curvature of the first surface of the display panel 1 makes it easier to damage the structure of the display panel 1. Therefore, even when both the first and second surfaces of the display panel 1 are curved, the connection method of the metal heat-conducting plate 3 provided in this embodiment can also avoid direct connection between the metal heat-conducting plate 3 and the display panel 1, thereby ensuring the display effect of the display panel 1.

[0071] Furthermore, the display module can also be a curved display module, and the display effect of the display module can still be guaranteed through the above connection method.

[0072] Furthermore, when the display module is a curved display module, the cover plate 2 is a curved cover plate, and the metal heat-conducting plate 3 is a flexible plate. This makes the compatibility of the cover plate 2, the metal heat-conducting plate 3, and the display panel 1 higher. At the same time, it allows the metal heat-conducting plate 3 to adapt to the curved surface of the display panel 1, thereby reducing the impact on the structure of the display panel 1.

[0073] Regarding the material of the metal heat-conducting plate 3, it can be a copper plate, aluminum plate, silver plate, or other heat-conducting materials, and this application embodiment does not limit this. In an optional embodiment, the metal heat-conducting plate 3 is an aluminum plate. Since the density of aluminum plate is relatively low compared to that of metal plates such as copper and iron plates, it can reduce the weight of the display module to a certain extent, which is conducive to the lightweight design of the display module. In addition, aluminum plate is easy to bend, which is conducive to creating conditions for connection with the cover plate 2.

[0074] In some embodiments, the area of ​​the orthographic projection of the first heat-conducting part 31 on the cover plate 2 is greater than or equal to the area of ​​the orthographic projection of the conductive adhesive 5 on the cover plate 2. This makes the first heat-conducting part 31 have a larger surface area relative to the conductive adhesive 5. This facilitates the connection between the cover plate 2 and the metal heat-conducting plate 3, while preventing the conductive adhesive 5 from overflowing and affecting the display panel 1 inside the metal heat-conducting plate 3.

[0075] Optionally, there is a gap between the third heat-conducting part 33 and the display panel 1. In this way, by leaving a gap between the third heat-conducting part 33 and the display panel 1, damage to the structure of the display panel 1 caused by the metal heat-conducting plate 3 can be avoided, which helps to ensure the integrity of the structure of the display panel 1.

[0076] Furthermore, the display module also includes thermal grease, which fills the gap between the third thermally conductive part 33 and the display panel 1. It should be noted that, because the gap between the third thermally conductive part 33 and the display panel 1 is filled with thermal grease, on the one hand, the thermal grease can protect the display panel 1; on the other hand, it avoids the possibility that the display panel 1 could indirectly contact the bent portion between the first thermally conductive part 31 and the second thermally conductive part 32, thus adding a heat transfer path for the display panel 1 and further facilitating heat transfer.

[0077] As can be seen from the above embodiments, in this application embodiment, the metal heat-conducting plate 3 is bent to form a receiving groove, the display panel 1 is placed in the receiving groove, the cover plate 2 covers the opening of the receiving groove, the two opposite ends of the metal heat-conducting plate 3 form a first heat-conducting part 31, the middle part of the metal heat-conducting plate 3 forms a second heat-conducting part 32, the flexible heat-conducting element 4 is disposed between the second heat-conducting part 32 and the display panel 1, and the first heat-conducting part 31 is connected to the edge of the cover plate 2, thus allowing the metal heat-conducting plate 3 to be directly connected to the cover plate 2. In this way, on the one hand, the connection between the metal heat-conducting plate 3 and the display panel 1 can be avoided from affecting the display effect of the display panel 1, and on the other hand, the charge on the surface of the cover plate 2 can be effectively conducted to the metal heat-conducting plate 3, reducing the risk of display defects such as greening of the display module. Furthermore, since the display panel 1 is set in the receiving groove, and a flexible heat-conducting element 4 is filled between the surface of the metal heat-conducting plate 3 facing the cover plate 2 and the first surface of the display panel 1, the flexible heat-conducting element 4 can not only increase the heat dissipation capacity of the display module, but also avoid the metal heat-conducting plate 3 from generating stress on the display panel 1 due to the elasticity and fluidity of the flexible heat-conducting element 4, thereby avoiding display defects such as orange peel texture in the display module and improving the display effect of the display module.

[0078] Secondly, embodiments of this application also provide an electronic device, which includes the display module described in any of the above embodiments.

[0079] It should be noted that the electronic device can be a mobile phone, tablet computer, laptop computer, handheld computer, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc., while the non-mobile electronic device can be a personal computer (PC), television (TV), ATM, or self-service machine, etc. The embodiments of this application do not make specific limitations.

[0080] It should be noted that when the electronic device includes a display module, the display module provided in this application embodiment not only increases the heat dissipation capacity of the electronic device but also avoids display defects such as orange peel texture, thereby improving the display effect of the display module. For example, when the display module included in this electronic device is applied to a car floating screen, because the display module improves both display effect and heat dissipation performance, the car floating screen can achieve a better visual effect while simultaneously providing heat dissipation performance, thus broadening the application scenarios of the display module.
