[0001] This invention relates to the field of display device technology, and more specifically to a display module and an electronic device. Background Technology

[0002] With the continuous development of display modules, they are increasingly moving towards thinner and lighter screens, wider viewing angles, flexible displays, and lower power consumption. Currently, flexible display modules need to be used in relatively complex working environments such as automotive or machine tools.

[0003] Then, because there is an angle between the flat area and the bent area of ​​the display module, when the flexible display module is used in a relatively complex working environment such as vehicle or machine tool, it is very easy for the display module to be damaged due to insufficient strength or insufficient heat dissipation, thereby reducing the service life of the display module. Summary of the Invention

[0004] This invention provides a display module and an electronic device to solve the problems of insufficient strength or heat dissipation in display modules in related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0006] In a first aspect, embodiments of the present invention provide a display module, the display module comprising: a display film layer, a heat dissipation film layer, a support plate, and an elastic heat-conducting sheet;

[0007] The display film layer and the heat dissipation film layer include a flat region and a bent region located on both sides of the flat region, and there is an angle between the tangent of the curved surface formed by the bent region and the plane where the flat region is located;

[0008] The display film layer is stacked on the first surface of the heat dissipation film layer;

[0009] The support plate is connected to the flat area of ​​the second surface of the heat dissipation film, and the elastic heat-conducting sheet is connected to the bent area of ​​the second surface of the heat dissipation film.

[0010] The first surface and the second surface are two opposing surfaces of the heat dissipation film layer.

[0011] Optionally, the heat dissipation film layer covers the elastic heat-conducting sheet, and there is a gap between the projection of the elastic heat-conducting sheet onto the heat dissipation film layer along a first direction and the edge of the heat dissipation film layer, wherein the first direction is a direction perpendicular to the tangent of the bending region.

[0012] Optionally, the projection of the elastic heat-conducting sheet onto the heat dissipation film layer along the first direction and the edge of the heat dissipation film layer have a gap greater than or equal to 0.5 mm and less than or equal to 1 mm.

[0013] Optionally, the elastic thermally conductive sheet is bonded to the bending area of ​​the second surface of the heat dissipation film layer by thermally conductive adhesive.

[0014] Optionally, the support plate is bonded to the bending area of ​​the second surface of the heat dissipation film layer by thermally conductive adhesive.

[0015] Optionally, the support plate is an aluminum plate.

[0016] Optionally, the elastic thermally conductive sheet is a thermally conductive silicone sheet.

[0017] Optionally, the display module includes a cover plate, a polarizer, a touch panel, and a display panel;

[0018] The display panel is stacked on the heat dissipation film layer, the touch panel is stacked on the display panel, the polarizer is stacked on the touch panel, and the cover plate is stacked on the polarizer.

[0019] Optionally, the heat dissipation film layer includes an insulating layer and a conductive layer;

[0020] The display panel is stacked on the insulating layer, the conductive layer covers the insulating layer, and the conductive layer is bonded to the support plate by the thermally conductive silicone.

[0021] Secondly, embodiments of the present invention also provide an electronic device, the electronic device including the display module described in any embodiment of the first aspect.

[0022] Optionally, the electronic device may further include a device body;

[0023] The main body of the device and the support plate are connected by thermally conductive silicone grease.

[0024] Optionally, the display module may also include a flexible heat-conducting sheet;

[0025] The elastic thermal conductive sheet is connected to the bending area of ​​the second surface of the heat dissipation film layer;

[0026] The elastic thermally conductive sheet is connected to the main body of the device via thermally conductive silicone grease.

[0027] Optionally, gaps exist between the thermal grease and the device body, and between the thermal grease and the elastic thermal pad.

[0029] Optionally, the display film layer and the device body are connected by an elastic sealant.

[0030] As can be seen from the above embodiments, in this embodiment of the invention, since the display film layer is stacked on the first surface of the heat dissipation film layer, and the support plate is connected to the flat area of ​​the second surface of the heat dissipation film layer, the flat area of ​​the heat dissipation film layer can be supported by the support plate. This reduces the shear force between the flat area and the bending area, and while increasing the strength of the display module, it also enhances the heat dissipation function of the flat area. Furthermore, since the elastic heat-conducting sheet is connected to the bending area of ​​the second surface of the heat dissipation film layer, heat in the bending area can be conducted, ensuring that both the bending and flat areas have components for heat dissipation. This results in uniform heat dissipation in both areas and avoids yellowing or other defects in the bending area. In summary, the display module provided by this embodiment of the invention improves the strength of the display module while enhancing its heat dissipation performance, further extending the lifespan of the display module.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do 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.

[0042] In a first aspect, embodiments of the present invention provide a display module. Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of the present invention. Figure 2 This indicates that an embodiment of the present invention provides a display module in... Figure 1 A magnified view of a portion of point A, as shown below. Figure 1 and Figure 2 As shown, the display module includes: a display film layer 1, a heat dissipation film layer 2, a support plate 3, and an elastic heat-conducting sheet 4; the display film layer 1 and the heat dissipation film layer 2 include a flat region 101 and a bent region 102 located on both sides of the flat region 101, and there is an angle between the tangent of the curved surface formed by the bent region 102 and the plane where the flat region 101 is located; the display film layer 1 is stacked on the first surface of the heat dissipation film layer 2; the support plate 3 is connected to the position of the flat region 101 on the second surface of the heat dissipation film layer 2, and the elastic heat-conducting sheet 4 is connected to the position of the bent region 102 on the second surface of the heat dissipation film layer 2, wherein the first surface and the second surface are two opposite surfaces of the heat dissipation film layer 2.

[0043] In this embodiment, the flat region 101 is the area containing the plane in the display module, and the bent region 102 is the area containing the curved surface in the display module. Typically, the bent region 102 is located at both ends of the flat region 101, bending away from the flat region 101 to form a curved surface, thereby increasing the display area of ​​the display module. In this embodiment, there is an angle between the tangent of the bent region 102 and the plane containing the flat region 101; that is, there is an angle between the tangent of the curved surface formed by the bent region 102 and the plane containing the flat region 101.

[0044] Because there is an angle between the tangent of the curved surface formed by the bending region 102 and the plane containing the flat region 101, there is a shear force between the bending region 102 and the flat region 101, which reduces the overall strength of the display module. To improve the strength of the display module, in this embodiment of the invention, a support plate 3 is connected to the flat region 101 on the second surface of the heat dissipation film layer 2. The support plate 3 can be a metal material with a certain strength and thermal conductivity, such as a copper plate, aluminum plate, or iron plate. This embodiment of the invention does not limit the type of support plate.

[0045] Furthermore, due to the thickness of the support plate 3, it is difficult to fit it snugly against the bending area 102, which can easily lead to uneven heat dissipation between the bending area 102 and the flat area 101. Consequently, when the display module operates in a high-temperature environment, yellowing and other defects may easily occur in the bending area 102. To avoid this problem, in the embodiments of the present invention, such as... Figure 2 As shown, the display module also includes an elastic heat-conducting sheet 4; the elastic heat-conducting sheet 4 is connected to the bending area 102 on the second surface of the heat dissipation film layer 2. In this way, the heat in the bending area 102 can be conducted through the elastic heat-conducting sheet 4, so that both the bending area 102 and the flat area 101 have components for heat dissipation, making the heat dissipation in the bending area 102 and the flat area 101 uniform, thereby avoiding defects such as yellowing in the bending area 102.

[0046] It should be noted that the elastic thermal conductive sheet 4 can be made of materials such as thermally conductive silicone or thermally conductive rubber, which have a certain degree of elasticity and good thermal conductivity. This embodiment of the invention does not limit this.

[0047] As can be seen from the above embodiments, in this embodiment of the invention, since the display film layer 1 is stacked on the first surface of the heat dissipation film layer 2, and the support plate 3 is connected to the flat area 101 of the second surface of the heat dissipation film layer 2, the flat area 101 of the heat dissipation film layer 2 can be supported by the support plate 3. This reduces the shear force between the flat area 101 and the bent area 102, and while increasing the strength of the display module, it also enhances the heat dissipation function of the flat area 101. Furthermore, since the elastic heat-conducting sheet 4 is connected to the bent area 102 of the second surface of the heat dissipation film layer 2, the heat in the bent area 102 can be conducted, ensuring that both the bent area 102 and the flat area 101 have components for heat dissipation. This results in uniform heat dissipation in both areas, preventing yellowing and other defects in the bent area 102. In summary, the display module provided by the embodiments of the present invention can improve the strength of the display module, enhance its heat dissipation performance, and further extend its service life.

[0048] In some embodiments, the support plate 3 is an aluminum plate. On the one hand, the aluminum plate can enhance the strength of the display module and provide sufficient support for the flat area 101 of the display module. On the other hand, since the density of the aluminum plate is relatively low compared to that of metal plates such as copper and iron plates, the weight of the support plate 3 can be reduced to a certain extent, which is beneficial to the lightweight design of the display module.

[0049] It should be noted that the first surface and the second surface are two opposing surfaces of the heat dissipation film layer 2. The first surface is the surface that is attached to the back of the display film layer 1, and the back of the display film layer 1 is the surface that is opposite to the surface from which the light is emitted from the display film layer 1.

[0050] In some embodiments, the support plate 3 is bonded to the bending area 102 of the second surface of the heat dissipation film layer 2 by thermally conductive adhesive 5. In this way, heat from the heat dissipation film layer 2 can be transferred to the support plate via the thermally conductive adhesive 5, and then from the support plate to the outside. Since the display film layer 1 is stacked on the first surface of the heat dissipation film layer 2, a heat dissipation path can be established from the display film layer 1 to the heat dissipation film layer 2, and from the heat dissipation film layer 2 to the support plate 3, thereby effectively preventing heat accumulation in the display film layer 1 and improving the display effect of the display film layer 1.

[0051] In some embodiments, the elastic thermally conductive sheet 4 is a thermally conductive silicone sheet. Since the thermally conductive silicone sheet has high thermal conductivity, excellent thermal conductivity, good electrical insulation, wide operating temperature, good stability, low consistency and good construction performance, after the thermally conductive silicone sheet is provided in the bending area 102 of the second surface of the heat dissipation film layer 2, the heat dissipation of the bending area 102 is satisfied. At the same time, due to the thermoplasticity and elasticity of the thermally conductive silicone sheet itself, it is easy to assemble the display module onto other parts. Moreover, during assembly, sufficient installation margin can be reserved by the thermally conductive silicone sheet.

[0052] Furthermore, the heat dissipation film layer 2 covers the elastic heat-conducting sheet 4, and there is a gap between the projection of the elastic heat-conducting sheet 4 on the heat dissipation film layer 2 along the first direction and the edge of the heat dissipation film layer 2.

[0053] It should be noted that there is a gap between the projection of the elastic heat-conducting sheet 4 onto the heat dissipation film layer 2 along the first direction and the edge of the heat dissipation film layer 2. That is, the end of the elastic heat-conducting sheet 4 and the end of the heat dissipation film layer 2 are misaligned, or in other words, the end of the elastic heat-conducting sheet 4 is recessed inward by a certain distance relative to the end of the heat dissipation film layer 2. In this way, the heat dissipation film layer 2 can completely cover the elastic heat-conducting sheet 4. On the one hand, this is beneficial to the heat transfer of the heat dissipation film layer 2. On the other hand, the elastic heat-conducting sheet 4 can provide a certain installation margin, thereby facilitating the assembly of the elastic heat-conducting sheet 4, the heat dissipation film layer 2 and other components.

[0054] Specifically, the projection of the elastic heat-conducting sheet 4 onto the heat dissipation film layer 2 along the first direction has a gap greater than or equal to 0.5 mm and less than or equal to 1 mm between the gap and the edge of the heat dissipation film layer 2. This allows for sufficient installation tolerance to be reserved between the elastic heat-conducting sheet 4 and the heat dissipation film layer 2, ensuring a tight fit between them.

[0055] Optionally, the elastic thermally conductive sheet 4 is bonded to the bending area 102 of the second surface of the heat dissipation film layer 2 using thermally conductive adhesive 5. In this way, heat from the heat dissipation film layer 2 can be transferred to the elastic thermally conductive sheet 4 via the thermally conductive adhesive 5, and then transferred to the outside by the elastic thermally conductive sheet 4. Since the display film layer 1 is stacked on the first surface of the heat dissipation film layer 2, a heat dissipation path can be established from the display film layer 1 to the heat dissipation film layer 2, and from the heat dissipation film layer 2 to the elastic thermally conductive sheet 4, thereby effectively preventing heat accumulation in the display film layer 1 and improving the display effect of the display film layer 1.

[0056] Furthermore, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the display module includes a cover plate 11, a polarizer 12, a touch panel, and a display panel 13; the display panel 13 is stacked on the heat dissipation film layer 2, the touch panel is stacked on the display panel 13, the polarizer 12 is stacked on the touch panel, and the cover plate 11 is stacked on the polarizer 12.

[0057] It should be noted that the cover plate is mainly used to protect the display panel 13 and to allow light to pass through. The cover plate 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 can be appropriately reduced. The cover plate can be a transparent glass cover plate, an acrylic plate, or a cover plate made of other materials; this embodiment of the invention does not limit this. The polarizer 12 is mainly used to dissipate surface reflections of the display panel and scatter light to increase the viewing angle of the display module. The touch panel is mainly used to realize the touch function of the display module. In some embodiments, the display module may not include the polarizer 12 and the touch panel, or the display module may include the polarizer but not the touch panel. When the display module is applied to an application environment that requires touch, it may include a touch panel. This embodiment of the invention does not limit this.

[0058] It should also be noted that, since the display panel 13 is stacked on the heat dissipation film layer 2, the touch panel is stacked on the display panel 13, the polarizer 12 is stacked on the touch panel, and the cover plate 11 is stacked on the polarizer 12, the heat of each layer in the display film layer 1 can be transferred to the heat dissipation film layer 2, and finally transferred to the outside through the support plate and the elastic heat-conducting sheet 4, thereby improving the heat dissipation function of the display module.

[0059] In some embodiments, the heat dissipation film layer 2 includes an insulating layer and a conductive layer; the display panel 13 is stacked on the insulating layer, the conductive layer covers the insulating layer, and the conductive layer is bonded to the support plate by thermally conductive silicone.

[0060] Specifically, the insulating layer may include foam, a mesh adhesive layer, and a polyimide film. The foam covers the surfaces opposite to the display panel 13 and the surface from which the light is emitted. The mesh adhesive layer is disposed between the polyimide film and the foam. The foam can be a low-density foam layer with many small pores, which facilitates rapid heat dissipation and provides a certain buffer for the display panel 13, thereby reducing damage to the display panel 13 when the heat dissipation film layer 2 is applied. The conductive layer can be a conductive copper layer covering the polyimide film. Since the conductive layer is bonded to the support plate with thermally conductive silicone, it ensures a tight fit between the layers while allowing charge transfer through the conductive layer and heat transfer from the conductive layer to the outside through the support plate.

[0061] As can be seen from the above embodiments, in this embodiment of the invention, since the display film layer 1 is stacked on the first surface of the heat dissipation film layer 2, and the support plate 3 is connected to the flat area 101 of the second surface of the heat dissipation film layer 2, the flat area 101 of the heat dissipation film layer 2 can be supported by the support plate 3. This reduces the shear force between the flat area 101 and the bent area 102, and while increasing the strength of the display module, it also enhances the heat dissipation function of the flat area 101. Furthermore, since the elastic heat-conducting sheet 4 is connected to the bent area 102 of the second surface of the heat dissipation film layer 2, the heat in the bent area 102 can be conducted, ensuring that both the bent area 102 and the flat area 101 have components for heat dissipation. This results in uniform heat dissipation in both areas, preventing yellowing and other defects in the bent area 102. In summary, the display module provided by the embodiments of the present invention can improve the strength of the display module, enhance its heat dissipation performance, and further extend its service life.

[0062] Secondly, embodiments of the present invention also provide an electronic device, which includes the display module described in any of the above embodiments.

[0063] 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, ATM, or self-service machine, etc. The embodiments of the present invention do not make specific limitations.

[0064] It should be noted that when the electronic device includes a display module, the display module provided by this embodiment of the invention improves both the strength and heat dissipation performance of the display module, further extending its lifespan. Therefore, the application scope of the display module in electronic devices is further expanded, freeing the electronic device from limitations imposed by the display module's performance. For example, when the display module included in this electronic device is applied to a car floating screen, the improved strength and heat dissipation performance not only enable the car floating screen to achieve better visual effects but also simultaneously provide both strength and heat dissipation. This allows for full utilization of the advantages of the display module's bending area, thereby broadening the application scenarios of the display module.

[0065] In some embodiments, the electronic device further includes a device body 6; the device body 6 and the support plate 3 are connected by thermally conductive silicone grease 7. It should be noted that, since the device body 6 and the support plate 3 are connected by thermally conductive silicone grease 7, the heat transferred from the display module to the support plate 3 can be transferred to the outside of the device body 6 through the thermally conductive silicone grease 7, and the connection between the flat area 101 of the display module and the device body 6 can be completed through the thermally conductive silicone grease 7.

[0066] Furthermore, the display module also includes an elastic thermal conductive sheet 4; the elastic thermal conductive sheet 4 is connected to the bending area 102 on the second surface of the heat dissipation film layer 2; the elastic thermal conductive sheet 4 is connected to the device body 6 through thermal grease 7.

[0067] Similarly, the flexible heat-conducting sheet 4 is connected to the device body 6 through the thermal grease 7. The heat transferred from the display module to the flexible heat-conducting sheet 4 can be transferred to the outside of the device body 6 through the thermal grease 7. The connection between the bending area 102 of the display module and the device body 6 can also be completed through the thermal grease 7.

[0068] Optionally, gaps exist between the thermal grease 7 and the device body 6, and between the thermal grease 7 and the elastic thermal conductive sheet 4. It should be noted that, due to the elasticity and thermoplasticity of the thermal grease 7, these gaps provide, on the one hand, installation slack for the connection between the device body 6 and the display module, facilitating installation and reducing damage to the display module structure during assembly. On the other hand, these gaps also provide space for thermal expansion and contraction, preventing the thermal grease 7 from causing bulges on the curved surface of the bending area 102 of the display module due to expansion, thus ensuring the display effect of the display module.

[0069] Furthermore, the gap between the thermal grease 7 and the elastic thermal pad 4 is greater than or equal to 0.5 mm and less than or equal to 1 mm. This allows for sufficient installation tolerances to be provided for the bonding between the thermal grease 7 and the elastic thermal pad 4, ensuring a tight fit between them.

[0070] In some embodiments, the display film layer 1 and the device body 6 are connected by an elastic sealant 8. This elastic sealant can be a foam adhesive, epoxy resin sealant, or other adhesive with a certain degree of elasticity. In this way, the elastic sealant 8 connects the display film layer 1 and the device body 6, completing the overall structure of the electronic device while simultaneously transferring heat from the display module, facilitating heat dissipation. Furthermore, because the elastic sealant 8 has a certain degree of elasticity, it provides a buffer for the bending area 102 of the display module, preventing structural damage to the bending area 102 under significant stress, thereby extending the service life of the display module.

[0071] As can be seen from the above embodiments, in the embodiments of the present invention, the support plate, the elastic heat-conducting component and the device body 6 can be connected by thermally conductive silicone grease 7 respectively, and then the display film layer 1 and the device body 6 can be connected by elastic sealant 8. In this way, while improving the strength of the display module of the electronic device, it can also help the display module dissipate heat and extend the service life of the electronic device.

[0072] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] Although alternative embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the alternative embodiments as well as all changes and modifications falling within the scope of the embodiments of the present invention.

[0074] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or terminal device.
