[0032] The LED display screen includes a display module and a box for supporting the display module. Currently, the box of the LED display screen is generally a fully enclosed structure. Since the display module in the box contains a large number of heat-generating components with high heat generation, such as circuit board components, a large amount of heat is accumulated inside the LED display screen and is difficult to dissipate, affecting the stability and reliability of the LED display screen.

[0033] Based on this, this embodiment provides a display module, which aims to solve the problem of insufficient heat dissipation of the existing display panel. Figure 1 This is a schematic diagram of the structure of the display module provided by the utility model.

[0034] See also Figure 1 The display module 100 includes a light source assembly 1 and a shell 2. The light source assembly 1 includes a circuit board assembly 11 and a lamp bead 12 electrically connected to the circuit board assembly 11. The material of the shell 2 includes thermal conductive plastic. The shell 2 wraps the circuit board assembly 11 and at least allows the lamp bead 12 to be exposed outward.

[0035] In the technical solution of this embodiment, since the thermally conductive plastic has good thermal conductivity, it can effectively conduct and dissipate the heat generated by the circuit board assembly 11, which helps to reduce the operating temperature of the LED assembly, reduce heat accumulation, and improve the stability and reliability of the system; and the thermally conductive plastic is stronger than traditional plastic materials, so that the structural strength of the shell 2 is higher, which helps to resist external impact and vibration and reduce the risk of mechanical damage; at the same time, compared with the metal heat dissipation structure, the thermally conductive plastic is lighter and cheaper, which can not only reduce the weight of the entire display device, but also reduce the cost of the display device. In addition, the thermally conductive plastic also has electrical insulation, which helps to prevent electrical problems such as circuit short circuits, so that the shell 2 can wrap the circuit board assembly 11. In this way, the shell 2 uses thermally conductive plastic so that the shell 2 can wrap the circuit board assembly 11, so as to increase the contact range between the shell 2 and the circuit board assembly 11, so that the shell 2 can conduct the heat of the circuit board in time, and at the same time, it can also expand the heat dissipation area of the shell 2 to prevent heat from accumulating in the shell 2, which is conducive to improving the heat dissipation capacity of the display module 100, thereby solving the problem of insufficient heat dissipation of the existing display light board.

[0036] Furthermore, there are many types of thermally conductive plastics. Specifically, in the present embodiment, the thermally conductive plastic includes polyimide, polyamide or a thermoplastic polymer filled with aluminum powder. Thus, the shell 2 is made of at least one of the materials such as polyimide, polyamide or a thermoplastic polymer filled with aluminum powder, so that the shell 2 can wrap the circuit board assembly 11, so as to conduct the heat of the circuit board assembly 11 in time and prevent the heat from accumulating in the shell 2.

[0037] In some embodiments, the circuit board assembly 11 has a back side facing away from the lamp bead 12, and the shell covers the back side of the circuit board assembly 11. Preferably, the shell 2 completely covers the back side of the circuit board assembly 11, so that the shell 2 is in full contact with the circuit board assembly 11 to achieve efficient heat dissipation.

[0038] In addition, to achieve the above purpose, the present embodiment further provides a display device, which includes a box and the above-mentioned display module 100. The display module 100 also includes a box 3 for mounting on a fixed wall, and the housing 2 is fixedly mounted on the box 3. Thus, by setting the box 3, the housing 2 is mounted to transfer the heat of the housing 2 to the fixed wall and the surrounding air, so as to prevent the heat from gathering in the box 3. It can be understood that there are many types of fixed walls, which can be walls or cabinet walls, etc., as long as they can support the box 3, and this embodiment does not limit this.

[0039] It should be noted that the structure of the display module 100 in the display device can refer to the embodiment of the above-mentioned display module 100, which will not be repeated here; since the above-mentioned display module 100 is used in the display device provided in this embodiment, the display device provided in this embodiment includes all technical solutions of all embodiments of the above-mentioned display module 100, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0040] In some embodiments, the box body 3 is provided with a mounting groove 31 for the shell 2 to be set. Thus, by providing the mounting groove 31 to accommodate the shell 2, the position of the shell 2 can be located on the box body 3, which is conducive to quickly installing the shell 2 on the box body 3, and the contact range between the shell 2 and the box body 3 can be increased, so that the heat of the shell 2 can be quickly transferred to the box body 3 to prevent heat from accumulating in the shell 2. Furthermore, the space between the mounting groove 31 and the shell 2 is filled with heat dissipation glue. Thus, by providing the heat dissipation glue to fill the gap between the box body 3 and the shell 2, it is helpful to improve the heat dissipation efficiency of the display module 100.

[0041] In some embodiments, the shell 2 is installed in the mounting groove 31 by interference fit. In this way, the shell 2 is installed in the box body 3 by interference fit, which can not only directly fix the shell 2 to the box body 3, but also make the shell 2 and the box body 3 close to avoid a gap between the shell 2 and the box body 3, so that the heat can be transferred from the shell 2 to the box body 3 in time, so as to be dissipated through the box body 3.

[0042] It should be noted that there are many ways to connect the shell 2 and the box 3. The shell 2 can be fixed to the box 3 by bonding or by screws, etc. This embodiment does not limit this.

[0043] In some embodiments, the thickness of the shell 2 is greater than the depth of the mounting groove 31 so that the lamp bead 12 can extend out of the box 3 to maintain the viewing angle of the display module 100 to prevent the light beam of the lamp bead 12 from being blocked due to the shell 2 being sunken in the box 3.

[0044] In some embodiments, a plurality of mounting grooves 31 are provided, and the plurality of mounting grooves 31 are arranged at intervals on the box body 3. Thus, by providing a plurality of mounting grooves 31, a plurality of housings 2 can be installed. Furthermore, there are various arrangements of the mounting grooves 31, and the plurality of mounting grooves 31 can be arranged at intervals along the width direction of the box body 3, can be arranged at intervals along the length direction of the box body 3, can be arranged in an array, etc., which is not limited in this embodiment.

[0045] In some embodiments, the box 3 includes a base 32 and a frame 33, the base 32 is used to be installed on the fixed wall, and the frame 33 is arranged on the base 32 to form a mounting groove 31 together with the base 32, wherein the material of the base 32 includes heat-conductive plastic, so that the base 32 uses heat-conductive plastic, which can not only reduce the weight of the base 32, but also transfer the heat of the box 3 to the fixed wall in time to prevent the heat from accumulating in the box 3, thereby helping to improve the heat dissipation capacity of the box 3. Further, there are many materials for the frame 33, the frame 33 can be a metal material such as iron, aluminum, or an alloy material such as steel, aluminum alloy, or an inorganic non-metal material such as nano-ceramics, which is not limited in this embodiment. Specifically, in this embodiment, the material of the frame 33 includes a metal material, so that the metal material can not only improve the strength of the box 3, so that the box 3 can effectively resist external impact, but also can dissipate the heat of the box 3 to the surrounding air in time, thereby helping to improve the heat dissipation effect of the box 3.

[0046] In some embodiments, the shell 2 fits the wall of the mounting groove 31 to avoid a gap between the shell 2 and the mounting groove 31, so that the heat of the shell 2 can be transferred to the box 3 in time to prevent heat from accumulating in the mounting groove 31, thereby helping to improve the heat dissipation effect of the display module 100.
