[0050] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] The display module is a component that can provide image display function. The current display module includes a backplane structure and a display panel located on the backplane structure. The backplane structure can be used to support the display panel, and the material of the backplane structure is metal.

[0053] However, the backplane structure made of metal has the problem of low thermal conductivity. In addition, for some display modules, there are dual requirements for weight and strength, and the current metal backplane structure is difficult to meet this requirement.

[0054] The embodiments of the present application provide a display module that can solve some problems existing in the above-mentioned related technologies.

[0055] Figure 1 is a schematic diagram of the structure of a display module provided in an embodiment of the present application ( Figure 1 The figure shows a schematic diagram observed from one side of the backplane structure). Figure 2 yes Figure 1 A schematic diagram of a cross-sectional structure of a display module shown in FIG. Figure 1 AA in the middle), please refer to Figure 1 as well as Figure 2 The display module 10 includes: a display panel 11, a back panel structure 12 and a display panel support 13.

[0056] The display panel support 13 is connected to the back plate structure 12 . The display panel 11 is located on the display panel support 13 , and a light emitting direction f1 of the display panel 11 is oriented in a direction away from the back plate structure 12 .

[0057] The back plate structure 12 includes a bottom plate 121 and side plates 122 extending from edges of the bottom plate 121 . At least a portion of the bottom plate 121 is made of carbon fiber. Figure 1 as well as Figure 2 It is shown that the material of a portion of the plate body in the area t of the bottom plate 121 includes carbon fiber.

[0058] Depending on the type of the display module, the display panel may also be a different display panel. For example, when the display module is an organic light-emitting diode (OLED) display module, the display panel may include an organic light-emitting diode display panel. When the display module is a liquid crystal display module, the display panel may include a liquid crystal display panel (LCD). Of course, the display module provided in the embodiment of the present application may also be other types of display modules, such as an electronic ink display module, etc. All types of display modules may apply the structure provided in the embodiment of the present application.

[0059] In summary, the embodiment of the present application provides a display module including a display panel, a back panel structure and a display panel support. In the display module, the back panel structure can be used to set the display panel support, and at least part of the material of the back panel structure includes carbon fiber. Since the heat dissipation capacity of carbon fiber is higher than that of metal plate, the back panel structure including carbon fiber provided in the embodiment of the present application can solve the problem of poor heat dissipation capacity of the display module in the related technology, thereby achieving the effect of improving the heat dissipation capacity of the display module.

[0060] Please refer to Table 1:

[0061] Table 1

[0062]

[0063] Among them, SUS304, SUS430, SGLC, GM55, GL57, AL5B59 and DA01 are models of various metals and alloys. Strength may refer to tensile strength, with the unit of megapascal (MPa). The tensile strength may reflect the maximum uniform plastic deformation resistance of various materials, and may also be considered as the maximum stress value that the material can withstand before breaking. The greater the tensile strength, the greater the strength of the material.

[0064] Thermal conductivity is also called thermal conductivity coefficient, and its unit is W / (mk) (Chinese: Watt / (meter·Kelvin)). Thermal conductivity refers to the amount of heat transferred through an area of ​​1 square meter in 1 second under stable heat transfer conditions, when the temperature difference between the two surfaces of a 1m thick material is 1 Kelvin.

[0065] The hardness may be expressed in Vickers hardness and the density may be expressed in grams per cubic centimeter.

[0066] It can be seen from Table 1 above that the thermal conductivity of carbon fiber is much higher than that of other metal materials, so the backplane structure including carbon fiber provided in the embodiment of the present application can improve the heat dissipation capacity of the backplane structure. The density of the carbon fiber is much lower than that of other metal materials, and the tensile strength and hardness of the carbon fiber are also greater than those of other metal materials except SUS304. However, since the density of SUS304 is too large, it cannot meet the current requirements for the weight of the corresponding display module. Therefore, the carbon fiber can meet the dual requirements for the weight and strength of the display module, but the other metal materials cannot meet this requirement.

[0067] In addition, carbon fiber itself is non-corrosive. After surface treatment, it can resist chemical and physical corrosion, which can improve the durability of the back panel structure using carbon fiber.

[0068] Also, please refer to Figure 3 , Figure 3It is a schematic diagram of a backplane structure, wherein the backplane structure may include area 1, area 2, area 3, area 4, and area 5. Since different areas of the display module may have different electronic components, some of the electronic components (such as the driver chip (S-IC), the timing controller (TCON) and capacitors on the circuit board, and the light bar in the backlight source, etc.) generate a large amount of heat, which will cause the temperature of the area near these electronic components to be higher than that of other areas. For example, the temperature difference of the five areas may be large, which may cause various structures in different areas (such as thin film transistors (TFT) and electroluminescent layers, etc.) to be affected by different temperatures, resulting in inconsistent display effects. On the other hand, when the display module includes a backlight source, various optical films in the backlight source may have problems such as wrinkles due to the large temperature difference between different areas.

[0069] Some current display modules are used in display devices with high refresh rates (such as refresh rates greater than 60 Hz) and / or portable display devices (such as notebooks, tablet computers, and various smart wearable devices such as virtual reality glasses). In such application scenarios, the problems of heat generation, weight, and strength are several problems that need to be overcome. For example, for a gaming laptop, the refresh rate of the display panel is high (such as 90 Hz, 120 Hz, 144 Hz, 165 Hz, and 240 Hz or higher), resulting in a large amount of heat generated by the display module, and thus certain requirements are placed on the heat dissipation performance of the display module. In addition, such laptops are also required to be light in weight and have high structural strength. The current backplane structure composed of metal is difficult to meet these requirements, but the display module provided in the embodiment of the present application includes a backplane structure of carbon fiber material, which can meet the requirements of the above-mentioned gaming laptop.

[0070] The backplane structure provided in the embodiment of the present application includes carbon fiber, which can improve the thermal conductivity and heat dissipation effects of the backplane structure, and further improve the temperature uniformity of various areas of the backplane structure, so as to solve the various problems caused by the poor thermal conductivity and heat dissipation performance of the backplane structure.

[0071] In addition, since the tensile strength and hardness of carbon fiber are both higher than those of conventional metals, the backplane structure including carbon fiber provided in the embodiment of the present application can also improve the structural strength of the backplane structure in the display module, thereby achieving the effect of improving the overall strength of the display module.

[0072] In addition, the density of carbon fiber is lower than that of conventional metal, and thus the backplane structure including carbon fiber provided in the embodiment of the present application can also reduce the weight of the backplane structure in the display module, thereby achieving the effect of reducing the overall weight of the display module.

[0073] Figure 4 Schematic diagram of another display module provided by the embodiment of the present application ( Figure 4 The figure shows a schematic diagram observed from one side of the backplane structure). Figure 5 yes Figure 4 A schematic diagram of a cross-sectional structure of a display module shown in FIG. Figure 1 BB), please refer to Figure 4 as well as Figure 5 , wherein the bottom plate 121 of the back plate structure 12 includes a bottom plate body b1 and at least one filling plate t1, the bottom plate body b1 includes at least one opening, at least one filling plate t1 is located in the at least one opening, the material of the bottom plate body b1 includes metal, and the material of the filling plate t1 includes carbon fiber. This structure is to set one or more openings on the back plate structure 12, and set the filling plate t1 including carbon fiber in the one or more openings. Exemplarily, the bottom plate body b1 may include four openings, the bottom plate 121 includes four filling plates t1, and the four filling plates t1 can be respectively located in the four openings on the bottom plate body b1. Among them, the material of the filling plate t1 may include carbon fiber. The filling plate t1 can be fixed in the opening of the bottom plate body b1 by thermoforming curing, tape curing, and glue curing.

[0074] In addition, when the display module is a liquid crystal display module, the display module may further include a reflector 141, a light guide plate 142, an optical film 143, a lower polarizer 144, an upper polarizer 145, and a fixing glue 146. The reflector 141, the light guide plate 142, and the optical film 143 may be sequentially stacked on the bottom plate 121 of the back plate structure 12, the lower polarizer 144 and the upper polarizer 145 may be located on both sides of the display panel 11, respectively, and the fixing glue 146 may be located between the display panel carrier 13 and the display panel 11, and is used to fix the display panel carrier 13 and the display panel 11. Among them, the light guide plate 142 can be used to connect the light bar ( Figure 5 The light emitted by the light guide plate 142 (not shown) is guided to the optical film 143, the upper polarizer 145 and the lower polarizer 144 are used to cooperate with the display panel 11 to realize the image display function, and the optical film 143 can improve the homogenization degree of the light provided by the light guide plate 142. Of course, the functions of these structures can also refer to the relevant technology, and the embodiments of the present application are not limited to this.

[0075] In the display module of this structure, the structure including carbon fiber can be located only in the opening of the bottom plate b1, so as to reduce the usage of carbon fiber and the manufacturing cost of the display module, and the carbon fiber will not affect the overall thickness of the bottom plate 121.

[0076] Among them, the optical film 143 may include multiple stacked film layers. The back panel structure provided in the implementation of the present application includes carbon fiber. The thermal conductivity of carbon fiber is greater than the thermal conductivity of metal, which can improve the temperature uniformity of various areas of the back panel structure, thereby reducing the risk of wrinkles in the optical film 143 due to uneven temperature in various areas.

[0077] It should be noted that the various structures including carbon fiber (such as filling plates, etc.) provided in the embodiments of the present application may include carbon fiber precursors and epoxy resins. For example, please refer to Figure 6 , Figure 6 Schematic diagram of the exploded structure of a carbon fiber plate in an embodiment of the present application. The carbon fiber structure may include a carbon fiber layer s1 composed of a plurality of stacked carbon fiber precursors, and an epoxy resin layer ( Figure 6 (not shown), wherein the thickness of the carbon fiber layer s1 can be about 0.03 mm, and the thickness of the epoxy resin layer can be between 0.015 mm and 0.02 mm. In addition, the length direction of the carbon fiber precursors in two adjacent carbon fiber layers s1 can have an angle (such as 1 degree to 90 degrees) to improve the overall strength. The carbon fiber structure can be a carbon fiber board.

[0078] Figure 7 is a structural schematic diagram of a backplane structure in a display module provided in an embodiment of the present application, Figure 8 yes Figure 7 A cross-sectional structural diagram of the backplane structure shown in FIG. Figure 8 Can be Figure 7 Cross-section at CC), Fig. 9 yes Figure 7 For a schematic diagram of the other side of the backplane structure shown, please refer to Figure 7 , Figure 8 as well as Fig. 9 The bottom plate 121 further includes a first plate body t2, at least one filling plate t1 is located on the first plate body t2, and the first plate body t2 is connected to one side of the bottom plate body b1. The material of the first plate body t1 includes carbon fiber, and the first plate body t1 can be a carbon fiber plate. Among them, at least one filling plate t1 can be connected to the first plate body t2 in a variety of ways. For example, at least one filling plate t1 can be connected to the first plate body t2 by thermoforming curing, glue curing, and tape curing, or at least one filling plate t1 can be an integral structure with the first plate body t2, and the embodiment of the present application is not limited to this.

[0079] In this structure, the structure including carbon fiber in the backplane structure may include a first plate body t2, and a plurality of filling plates t1 located on the first plate body t2. When at least one filling plate t1 and the first plate body t2 can be an integral structure, the overall stability of the integral structure formed by the first plate body t2 and the filling plates t1 located on the first plate body t2 is high, and a stable connection can be achieved with the bottom plate body b1 of the backplane structure. And because the first plate body t2 is widely distributed, heat can be quickly transferred to the entire backplane structure, which can further improve the temperature uniformity of various areas of the backplane structure. Among them, the first plate body t2 can be connected to one side of the bottom plate body b1 in a variety of ways, such as thermoforming curing, glue curing, and tape curing.

[0080] in addition, Figures 7 to 9 The structure shown is that the first plate body t2 is located on the outside of the bottom plate body b1, but the first plate body t2 can also be located on the inside of the bottom plate body b1. For example, please refer to Fig.10 , Fig.10 It is a schematic diagram of another backplane structure provided in an embodiment of the present application. In this figure, the first plate body t2 can also be located on the inner side of the bottom plate body b1 and fit with the filling plate t1 located in the opening of the bottom plate body b1.

[0081] Fig.11 yes Figure 7 Another cross-sectional structural diagram of the backplane structure shown in FIG. Fig.11 Can be Figure 7 For the cross-sectional view at CC, please refer to Fig.11 as well as Figure 7 , wherein the edge of the opening includes a protruding structure g1 and a recessed structure g2 arranged in sequence along a direction f2 close to the filling plate t1, the protruding structure g1 protrudes in a direction f3 away from the display panel, and the recessed structure g2 is recessed in a direction f4 close to the display panel; the first plate body t2 is connected to a side of the recessed structure g2 away from the display panel.

[0082] With such a structure, on the one hand, a structure similar to a reinforcing rib (this structure can be called a double punch structure) can be formed through the protruding structure g1 and the recessed structure g2, which can improve the overall structural strength of the backplane structure, reduce the possibility of warping of the backplane structure, and improve the flatness of the backplane structure.

[0083] On the other hand, the first plate body t2 can be provided by the recessed structure g2, so that the influence of the first plate body t2 on the thickness of the bottom plate body in the back plate structure can be reduced. Exemplarily, the recessed depth of the recessed structure g2 can be equal to or greater than the thickness of the first plate body t2.

[0084] It should be noted that the filling plate t1 may include multiple stacked carbon fiber layers, and the first plate body t2 may also include multiple stacked carbon fiber layers. The filling plate t1 may be an integral structure formed once with the first plate body t2, or may be formed separately and then connected (for example, by thermoforming and curing) as an integral structure, and the embodiments of the present application are not limited to this. Exemplarily, the filling plate t1 may include 1 to 3 layers of carbon fiber layers, and the thickness of the filling plate t1 may be substantially the same as the thickness of the bottom plate body, or the thickness of the filling plate t1 may be less than the thickness of the bottom plate body. For example, when the thickness of the bottom plate body is 0.2 mm, the thickness of the filling plate t1 may range from 0.15 mm to 0.2 mm; when the thickness of the bottom plate body is 0.3 m, the thickness of the filling plate t1 may range from 0.2 mm to 0.3 mm.

[0085] Fig.12 yes Figure 7 Another cross-sectional structural diagram of the backplane structure shown in FIG. Fig.12 Can be Figure 7 For the cross-sectional view at CC, please refer to Fig.12 as well as Figure 7 , wherein the bottom plate 121 includes a first plate body t2 and a second plate body t3, at least one filling plate t1 is located on the first plate body t2, and at least one filling plate t1 and the first plate body t2 are an integral structure, and the first plate body t2 is connected to one side of the bottom plate body b1. The second plate body t3 is connected to at least one filling plate t1, and the second plate body t3 is connected to the other side of the bottom plate body b1. The materials of the first plate body t2, the second plate body t3 and the filling plate t1 all include carbon fiber, and the first plate body t2, the second plate body t3 and the filling plate t1 can all be carbon fiber plates. Under this structure, the first plate body t2 or the second plate body t3 can be an integral structure with at least one filling plate t1, so that the stability and firmness of the overall structure can be improved.

[0086] In this way, two carbon fiber plates are formed on both sides of the bottom plate b1, surrounding the filling plate t1 in the opening. This structure can further improve the stability of the combined structure of the carbon fiber structure and the bottom plate formed by the first plate t2, the second plate t3 and the filling plate t; and the two plates on both sides of the bottom plate b1 can clamp the bottom plate b1 to balance the temperature of each area of ​​the back plate structure on both sides of the bottom plate b1, and both plates are in contact with the filling plate in the opening, so that the temperature of the two plates on both sides of the bottom plate can be balanced by the filling plate, so as to further improve the uniformity of the temperature of each area of ​​the back plate structure, reduce various problems of the display module caused by uneven temperature in each area, and improve the display effect and stability of the display module.

[0087] In addition, in the carbon fiber structure composed of the first plate t2, the second plate t3 and the filling plate t, the two plates can interact with each other and clamp the bottom plate b1 from both sides of the bottom plate b1 to reduce the warping problem caused by the different materials of the carbon fiber structure and the bottom plate b1, improve the flatness of the back plate structure, avoid the problem of affecting some structures inside the display module (such as the light guide plate, etc.) due to warping, and improve the display effect of the display module.

[0088] In an exemplary embodiment, the thickness of the second plate t3 is equal to the thickness of the first plate t2. In this structure, the second plate t3 and the first plate t2 can offset the warping problem caused by the different shrinkage rates of the carbon fiber material and the material of the bottom plate, so as to further improve the flatness of the back plate structure, avoid the problem of affecting some structures inside the display module due to warping, and improve the display effect of the display module.

[0089] In addition, for Fig.12 The back panel structure of the display module shown in the figure can be provided with recessed structures on both sides of the edge of the opening, and the edges of the first plate t2 and the second plate t3 can be located in the recessed structures. In this way, the influence of the carbon fiber structure composed of the first plate t2, the second plate t3 and the filling plate t on the overall thickness of the base plate 121 can be reduced, and the recessed structure can limit the first plate t2 and the second plate t3 to enhance the stability of the connection between the carbon fiber structure composed of the first plate t2, the second plate t3 and the filling plate t and the base plate b1.

[0090] In addition, the back plate structure may also include some other structures. The materials of some of the back plate structures include metal materials, and these structures may be arranged on the bottom plate 121 or the side plate 122. For example, please refer to Fig.13 , Fig.13 yes Figure 7 Another cross-sectional structural diagram of the backplane structure shown in FIG. Fig.13 Can be Figure 7 For the cross-sectional view at DD, please refer to Fig.13 as well as Figure 7 , wherein the back plate structure 12 further includes a U-fold structure extending from the side plate 122, the material of the U-fold structure 123 may include a metal material, and the U-fold structure 123 may be an integral structure with the side plate 122. Compared with being set on carbon fiber, since the materials of the U-fold structure 123 and the side plate 122 both include a metal material, the manufacturing difficulty of the U-fold structure 123 and the side plate 122 can be reduced.

[0091] Fig.14 yes Figure 7 Another side view of the backplane structure shown in the figure, please refer to Fig.14 as well as Figure 7 , wherein the back panel structure also includes a circuit board support bracket 124 extending from the side panel 122, and the bracket can be used to support the circuit board. The material of the circuit board support bracket 124 can include a metal material, and the circuit board support bracket 124 can be an integral structure with the side panel 122. Compared with being set on carbon fiber, setting the circuit board support bracket 124 on the side panel 122 including a metal material can also reduce the manufacturing difficulty of the circuit board support bracket 124 and the side panel 122. Of course, some other structures in the back panel structure, such as the double support structure, can be set on the bottom plate body and the side panel including a metal material, and the embodiments of the present application are not limited to this.

[0092] The back panel structure provided in the above-mentioned embodiment has an opening in the shape of a rectangle, but in the display module provided in the embodiment of the present application, the shape of the opening on the base plate body of the back panel structure can also be other shapes, for example, the shape of the opening on the base plate body includes at least one of a rectangle, a trapezoid, a triangle and a rhombus, at least one filling plate corresponds one-to-one to at least one opening, and the shape of the filling plate is similar to the shape of the corresponding opening.

[0093] For example, please refer to Fig.15 , Fig.15 Schematic diagrams of several backplane structures in the display module provided in the embodiments of the present application are shown, among which, c1 shows that the number of openings on the bottom plate body b1 is 4, the shapes of the four openings are all triangles, and the shape of the corresponding filling plate t1 is also triangle; c2 shows that the number of openings on the bottom plate body b1 is 2, the shapes of the two openings are all rectangles, and the shape of the corresponding filling plate t1 is also rectangle; c3 shows that the number of openings on the bottom plate body b1 is 4, the shapes of the four openings are all trapezoids, and the shape of the corresponding filling plate t1 is also trapezoidal; c4 shows that the number of openings on the bottom plate body b1 is 2, the shapes of the two openings are all triangles, and the shape of the corresponding filling plate t1 is also triangle.

[0094] Of course, in the display module provided in the embodiment of the present application, the shapes of the opening on the bottom plate and the corresponding filling plate may also be other shapes, and the embodiment of the present application does not limit this.

[0095] also, Fig.15 Several backplane structures are shown, and each backplane structure includes only one shape of opening. However, the backplane structure of the display module provided in the embodiment of the present application may also include openings of at least one shape of rectangle, trapezoid, triangle and rhombus. For example, a backplane structure may include triangular openings and rectangular openings, or a backplane structure may include triangular openings, rectangular openings and trapezoidal openings, etc. The embodiments of the present application will not be repeated here.

[0096] In addition, due to the backplane structure provided in the embodiment of the present application, the heat dissipation capacity of the display module can be greatly improved, and thus there is no need to use graphene heat dissipation tape in the display module, thereby reducing the manufacturing cost of the display module, simplifying the manufacturing process and simplifying the structure.

[0097] In summary, the embodiment of the present application provides a display module including a display panel, a back panel structure and a display panel support. In the display module, the back panel structure can be used to set the display panel support, and at least a portion of the back panel structure is carbon fiber. Since the heat dissipation capacity of carbon fiber is higher than that of metal plate, the back panel structure including carbon fiber provided in the embodiment of the present application can solve the problem of poor heat dissipation capacity of the display module in the related technology, thereby achieving the effect of improving the heat dissipation capacity of the display module.

[0098] In addition, since the tensile strength and hardness of carbon fiber are highly comparable to those of conventional metals, the backplane structure including carbon fiber provided in the embodiment of the present application can also improve the structural strength of the backplane structure in the display module, thereby achieving the effect of improving the overall strength of the display module.

[0099] In addition, the density of carbon fiber is lower than that of conventional metal, and thus the backplane structure including carbon fiber provided in the embodiment of the present application can also reduce the weight of the backplane structure in the display module, thereby achieving the effect of reducing the overall weight of the display module.

[0100] In the display module provided in the above embodiment, part of the back plate structure is a carbon fiber structure whose material includes carbon fiber, but in the display module provided in the embodiment of the present application, the materials of the bottom plate and the side plate in the back plate structure may both include carbon fiber, that is, the bottom plate and the side plate may both be carbon fiber plates.

[0101] Please refer to Fig.16 , Fig.16 1 is a schematic diagram of a structure of a display module shown in an embodiment of the present application, wherein the materials of the bottom plate 121 and the side plate 122 in the back plate structure may both include carbon fiber. In addition, the material of the display panel support 13 in the display module may include plastic, or the material of the display panel support 13 may include carbon fiber. When the material of the display panel support 13 includes carbon fiber, the display panel support 13 may include multiple stacked carbon fiber layers.

[0102] In an exemplary embodiment, the display panel support member 13 including a plurality of stacked carbon fiber layers may be an integral structure with the side panel 122 . Fig.17 yes Fig.16 A schematic diagram of the bottom plate 12 during the manufacturing process is shown in FIG. Fig.16 as well as Fig.17, wherein, when manufacturing the bottom plate 12, a carbon fiber board tb can be formed, and a display panel support 13 including a plurality of stacked carbon fiber layers can be formed at a preset position of the carbon fiber board tb, and then a back plate 12 including a side plate 122 and a bottom plate 121 can be formed by a bending process, and then the side plate 122 has a display panel support 13, and the display panel can be supported by the display panel support 13 including carbon fiber. In this way, on the one hand, the overall weight of the display module can be further reduced while ensuring the strength, and on the other hand, the display panel support 13 can facilitate the heat on the display panel 11 and other structures to be transferred to the back plate structure 12 by the display panel support 13, thereby improving the heat dissipation performance of the display module.

[0103] In addition, the display panel support 13 including multiple stacked carbon fiber layers can also be formed separately from the back plate, and then the display panel support 13 is connected to the back plate. Exemplarily, the display panel support 13 including multiple stacked carbon fiber layers can be bonded to the side plate 122. Alternatively, the display panel support 13 can be connected to the side plate 122 by hot pressing, which is not limited in the embodiment of the present application.

[0104] When the display panel in the display module is a rectangular panel, the back plate structure can also be rectangular, and the four edges of the back plate structure can be provided with Fig.16 The display panel support 13 shown is used to support the display panel. Of course, a U-fold structure can also be provided at one edge of the backplane structure (such as an edge close to the light bar, or an edge where the display panel is connected to the control unit) to support the display panel.

[0105] Exemplarily, one side of the back plate may also include a U-fold structure. For example, please refer to Fig.18 , Fig.18 1 is a schematic diagram of a back plate structure of a display module provided in an embodiment of the present application, wherein the back plate structure further includes an L-shaped support plate 125, the L-shaped support plate 125 includes a connecting plate 1251 and a support plate 1252 connected to one end of the connecting plate 1251, and the connecting plate 1251 and the support plate 1252 are an integral structure. The material of the L-shaped support plate 125 includes carbon fiber, and the L-shaped support plate 125 can be formed by bending a carbon fiber plate.

[0106] One side of the connecting plate 1251 is connected to one side of the first side plate 1221, and the first side plate 1221 is a side plate 122 connected to an edge of the bottom plate 121. The support plate 1252 is located on the side of the first side plate 1221 close to the bottom plate 121. In this way, the L-shaped structure formed by the L-shaped support plate 125 and the other L-shaped structure formed by the first side plate 1221 and the bottom plate 121 can form a U-fold structure together, and the U-fold structure can be used to support the display panel, and compared with the display panel support 13, the U-fold structure can improve the stability of the support for the display panel. In addition, the U-fold structure composed of carbon fiber provided in the embodiment of the present application, due to the high material strength of the carbon fiber in the present application, can improve the stability of the support of the U-fold structure for the display panel, and can improve the overall structural strength of the display module, when the display module is applied to the field of portable devices (such as laptops, tablet computers and various smart wearable devices), it can greatly improve the structural strength of such portable devices and improve the durability of such portable devices.

[0107] Since carbon fiber boards are difficult to process, in the back panel structure provided in the embodiment of the present application, two L-shaped structures together form a U-fold structure made of carbon fiber, which can reduce the manufacturing difficulty and manufacturing cost of the U-fold structure made of carbon fiber.

[0108] In an exemplary embodiment, the thickness of the connecting plate 1251 is less than the thickness of the supporting plate 1252;

[0109] The thickness of the first side plate 1221 is less than that of the bottom plate 121. Such a structure can reduce the thickness of the side plate body formed by the connecting plate 1251 and the first side plate 1221, so as to reduce the influence of the side plate body on other structures. Exemplarily, the thickness of the connecting plate 1251 can be 1 / 2 to 2 / 3 of the thickness of the supporting plate 1252, and the thickness of the first side plate 1221 can be 1 / 2 to 2 / 3 of the thickness of the bottom plate 121.

[0110] One side of the connecting plate 1251 and one side of the first side plate 1221 may be connected in various ways, for example, one side of the connecting plate 1251 and one side of the first side plate 1221 may be bonded together, for example, by hot pressing.

[0111] In some tests, the display module provided in the embodiments of the present application also achieved improvements in problems such as light leakage. For example, for the solution in which part of the structure of the back panel provided in the above embodiments includes carbon fiber, in an exemplary embodiment, compared with a display module with a back panel structure composed of SUS304 (304 stainless steel), a 16-inch display module provided in the embodiments of the present application, the mass of the back panel including carbon fiber can be reduced by 56 grams, and the mass of light leakage caused by the weight can be increased by 90 grams to 100 grams (the mass of light leakage caused by the weight can be considered to be the mass of the weight set on the back panel structure when the display module leaks light due to the weight set on the back panel structure. The larger the mass, the greater the strength of the back panel structure).

[0112] For the full carbon solution in which the bottom plate and the side plates in the back plate provided in the above-mentioned embodiment both include carbon fiber, in an exemplary embodiment, compared with a display module with a back plate structure composed of GM55 (a high-strength aluminum material), in a 14-inch display module provided in an embodiment of the present application, the mass of the back plate composed entirely of carbon fiber can be reduced by 20 grams, and the mass of the weight light leakage can be increased by 50 grams.

[0113] It can be seen that the two display modules provided in the embodiments of the present application can both achieve the effect of improving structural strength.

[0114] In addition, due to the backplane structure provided in the embodiment of the present application, the heat dissipation capacity of the display module can be greatly improved, and thus there is no need to use graphene heat dissipation tape in the display module, thereby reducing the manufacturing cost of the display module, simplifying the manufacturing process and simplifying the structure.

[0116] In addition, since the tensile strength and hardness of carbon fiber are highly comparable to those of conventional metals, the backplane structure including carbon fiber provided in the embodiment of the present application can also improve the structural strength of the backplane structure in the display module, thereby achieving the effect of improving the overall strength of the display module.

[0117] In addition, the density of carbon fiber is lower than that of conventional metal, and thus the backplane structure including carbon fiber provided in the embodiment of the present application can also reduce the weight of the backplane structure in the display module, thereby achieving the effect of reducing the overall weight of the display module.

[0118] In addition, an embodiment of the present application further provides a display device, which may include a housing and the display module provided in the above embodiment, and the display module is located in the housing.

Since the display device includes the display module provided in the above embodiment, and based on the effect that can be achieved by the above display module, the display device can also be provided with a backplane structure including carbon fiber provided in the embodiment of the present application, because the heat dissipation capacity of carbon fiber is higher than that of metal plate, the problem of poor heat dissipation capacity of the display device in the related art is solved, and the effect of improving the heat dissipation capacity of the display device is achieved.

[0120] In addition, since the tensile strength and hardness of carbon fiber are highly comparable to those of conventional metals, the backplane structure including carbon fiber provided in the embodiment of the present application can also improve the structural strength of the backplane structure in the display module, thereby achieving the effect of improving the overall strength of the display module.
