[0048] The driving component may include a plurality of first components and a plurality of second components. The first components may be installed in a first installation area, and the second components may be arranged in a second installation area.

[0049] The power level of the second component may be lower than the power level of the first component, that is, the heat generation rate of the second component during operation is lower than the heat generation rate of the first component.

[0050] The first component can be set as a high-power device such as a power board, a main board and a driver board.

[0051] The driver board is mainly used to operate the control system and output relevant operation instructions accordingly. In some embodiments, the power board is integrated on the driver board, and is mainly used to provide a driving voltage or a stable working voltage to the driver board, and to keep the output current stable when the circuit on the driver board is working.

[0052] The second component can be set to a low-power device such as a speaker, a WiFi module, etc.

[0053] The speaker can be used to produce corresponding sounds in coordination with the interface displayed on the display panel 1. The WiFi module can be used to receive network signals.

[0054] The first mounting area 22 may be located at the lower end of the back of the back plate 2 and extend along the lower edge of the back plate 2. The second mounting area 23 may be located at one side of the first mounting area 22 and also extend along the lower edge of the back plate 2.

[0055] Two second installation areas 23 may be provided, and the two second installation areas 23 are respectively provided on the left and right sides of the first installation area 22 .

[0056] Figure 4 yes Figure 1 Schematic diagram of the structure of the rear shell assembly of the display device.

[0057] See also Figure 4 The rear shell assembly 3 can be arranged on the back side of the back plate 2.

[0058] The rear shell assembly 3 may include a first rear shell 31 and a second rear shell 32 that are spliced ​​together. The first rear shell 31 may cover the first installation area 22 , and the second rear shell 32 may cover the second installation area 23 .

[0059] The flame retardant grade of the material of the second rear case 32 may be lower than the flame retardant grade of the material of the first rear case 31 .

[0060] The first rear shell 31 may be installed at the first installation area 22 on the back side of the back plate 2 , and a first installation cavity (not shown in the figure) may be formed between the first rear shell 31 and the rear wall of the back plate 2 .

[0061] The second rear shell 32 can be installed at the second installation area 23 on the back side of the back plate 2 , and a second installation cavity (not shown in the figure) can be formed between the second rear shell 32 and the rear wall of the back plate 2 .

[0062] In some embodiments, the height dimension of the first mounting area 22 may be greater than the height dimension of the second mounting area 23 , so that the space in the first mounting cavity is greater than the space in the second mounting cavity.

[0063] See also Figure 3 A second installation cavity can be formed on both sides of the first installation cavity, that is, two second installation cavities are provided, and the two second installation cavities can be respectively provided on the left and right sides of the first installation cavity.

[0064] The second installation cavity can be used to install components such as speakers and WiFi modules (not shown in the figure). Among them, multiple speakers can be provided, and the multiple speakers can be separately arranged in the two second installation cavities.

[0065] Specifically, since the first components such as the main control board, power board, and electronic devices are mainly concentrated in the first installation cavity, that is, the main dangerous flame source is concentrated in the first installation cavity. Therefore, the first rear shell 31 is made of flame-retardant material. The first components such as the main control board, power board, and electronic devices will generate heat when working. If the first components suddenly catch fire when working, the flame-retardant property of the first rear shell 31 can prevent the fire from affecting itself, and prevent the first rear shell 31 from catching fire and the spread of the fire.

[0066] The second installation cavity mainly installs components such as speakers and WiFi modules, which generate relatively less heat during operation. Compared with the first installation area 22, the second installation area 23 has a lower probability of catching fire. Therefore, the second rear shell 32 can be made of a material with a lower flame retardancy level than the first rear shell 31, such as a slow-burning material, which can reduce the flame retardancy level requirements of the second rear shell 32 material while ensuring the safety of the second rear shell 32.

[0067] In addition, the second rear shell 32 is made of a material different from that of the first rear shell 31 , which can reduce the production cost of the rear shell assembly 3 product.

[0068] It should also be noted that in other embodiments, the first components such as the main control board, power board, and electronic devices can be concentrated in the second installation cavity. In this case, the second rear shell 32 is made of flame-retardant material, and the first rear shell 31 can be made of a material with a lower flame-retardant grade than the second rear shell 32, such as a slow-burning material, so as to reduce the flame-retardant grade requirement of the material of the first rear shell 31 and reduce the production cost of the product.

[0069] In some embodiments, the display device may further include a control board (not shown in the figure) and a plurality of external connectors (not shown in the figure). The control board and the plurality of external connectors are arranged in the first installation cavity, that is, the control board and the plurality of external connectors can be installed in the first installation area 22.

[0070] See also Figures 2 to 4 The rear shell assembly 3 may include two second rear shells 32. The two second rear shells 32 may be respectively arranged on the left and right sides of the first rear shell 31, and spliced ​​with the first rear shell 31 to form an integral rear shell assembly 3.

[0071] Specifically, the two second rear shells 32 can be spliced ​​and connected to the two side edges of the first rear shell 31 respectively.

[0072] The two second rear shells 32 may be symmetrically arranged, such that the two second rear shells 32 can be symmetrically arranged on both sides of the first rear shell 31 .

[0073] At the same time, since two second installation areas 23 can be formed on the back side of the back plate 2, the two second installation areas 23 are located on the left and right sides of the first installation area 22, so that the two second rear shells 32 can be set in a one-to-one correspondence with the two second installation areas 23.

[0074] Figure 5 yes Figure 1 Schematic diagram of the structure of the first rear shell of the display device. Figure 6 yes Figure 1 Schematic diagram of the structure of the second rear shell of the display device. Figure 7 yes Figure 1 Schematic diagram of the exploded view of the rear shell assembly of the display device. Figure 8 yes Figure 7 A magnified view of point A.

[0075] See also Figure 5-8 The first rear shell 31 may be provided with a lap joint 311. The second rear shell 32 may be provided with a connection portion 321, and the connection portion 321 is located on a side of the second rear shell 32 facing the first rear shell 31.

[0076] The connecting portion 321 can be fixed on the overlapping portion 311, so that the second rear shell 32 and the first rear shell 31 form a whole. That is, the second rear shell 32 can be fixed on the overlapping portion 311 of the first rear shell 31 through the connecting portion 321, so that the second rear shell 32 can be fixed on the first rear shell 31, and then the first rear shell 31 and the second rear shell 32 on the rear shell assembly 3 can be connected into a whole first, and then the rear shell assembly 3 can be directly installed on the back plate 2.

[0077] Therefore, after the first rear shell 31 and the second rear shell 32 of the rear shell assembly 3 are connected into a complete body, they are installed on the back panel 2, so that when the display device is assembled, the installation process of the rear shell assembly 3 on the production line can be simplified, that is, the process of installing multiple rear shells is simplified to the process of installing an integral rear shell, thereby improving the installation and production efficiency of the display device.

[0078] See also Figure 5 , Figure 7 and Figure 8 The left and right sides of the first rear shell 31 may both be provided with overlapping parts 311.
