In some examples of the present embodiment, the display support module 60 is mounted on the side sill of the middle frame 10, and in still other examples, the display support module 60 is mounted on the middle sill of the middle frame 10. In some examples of the present embodiment, the display support module 60 also supports both attachment and detachment from the front side of the middle frame 10 and attachment and detachment from the rear side of the middle frame 10. Therefore, in some examples of the present embodiment, the display support module 60 is fixed on the middle frame 10 using a double-operation-end fixing member. As the name implies, the dual operation end fixing member has two operation ends respectively located at the front and rear sides of the middle frame 10, and both operation ends support the display support module 60 to be disassembled and assembled, for example, in some examples, the dual operation end fixing member may be a stud having a concave pattern on both end surfaces, in other examples, the dual operation end fixing member may be a stud, and in still other examples, the dual operation end fixing member for fixing the display support module 60 may be a stud pin.

The following is a simple description of the rest of the structure of the display module: referring to fig. 10, the display module 40 includes a lamp panel 401 and a bottom chassis 402, and a chip array including a plurality of light emitting chips, such as at least one of an LED array, a Micro-LED array, a Mini-LED array, and an OLED array, is disposed on the lamp panel 401. The lamp panel 401 is fixed to the front side of the bottom housing 402, and when the display module assembly 40 is mounted on the middle frame, the rear side of the bottom housing 402 faces the rear side of the middle frame.

It should be understood that the operation of the display module 40 requires current driving and also needs to receive a display control signal, so that it needs to be electrically connected and signal connected with the display support module 60 disposed on the middle frame, and therefore, a power interface corresponding to a power supply and a signal interface corresponding to a signal adapter board are disposed on the display module 40. For the display module 40, these interfaces all belong to the external interfaces of the display module 40, and are used for connecting with the module interface on the middle frame. In some examples of the present embodiment, the display module 40 further includes a distributing board 403, for example, as shown in fig. 10, the distributing board 403 is disposed at a rear side of the bottom case 402, that is, a side of the bottom case 402 opposite to the lamp panel 40. The external interfaces of the display module 40 are disposed on the distributing board 403, and in some examples of the present embodiment, only one set of external interfaces is disposed on the distributing board 403, and the set of external interfaces includes various interfaces that need external connection for the display module 40 to work. The set of external interfaces may be disposed in the middle region of the distribution board 403, or may be disposed in a region on one side of the distribution board 403, such as the left side or the right side, and such as the upper side or the lower side. In general, a middle frame is divided into a left area and a right area by a middle beam, and the two areas are respectively provided with a display module 40; meanwhile, the display support module is usually located in the middle of the middle frame, for example, on the middle beam, so if one display module 40 is disposed on the left side of the middle frame, its external interface is preferably located on the right side of the line distribution board (in this embodiment, when describing the position of the external interface on the line distribution board 403, the distinction between the left and right sides is referred to as the direction facing the display surface of the display module 40), and if the display module 40 is disposed on the right side of the middle frame, its external interface is preferably located on the left side of the line distribution board. Therefore, in some examples of the present embodiment, the display module 40 mounted on the middle frame is divided into two types, in which case, when the engineer mounts the display module on the middle frame, the engineer also needs to distinguish the mounting position of the display module on the middle frame according to the position of the external interface on the display module. However, in some other examples of this embodiment, the wire distributing board includes two sets of external interfaces, for example, please refer to fig. 11: in the display module 40 shown in fig. 11, the external interface 4030 is provided on both the left side and the right side of the distributing board 403, and the external interface 4030 is a left-side interface and a right-side interface, so that the display module 40 is supported to be installed on both the left side and the right side of the middle frame, and it is not necessary for an engineer to distinguish the installation position of the display module 40 during field installation, which enhances the universality of the display module 40 and improves the installation efficiency of the display module 40.

Some examples of the present invention provide a display device, in which at least one of the power supply and the signal adapter board in the display support module is dual-backed up, for example, in an example, a display device simultaneously includes a main power supply and at least one standby power supply, a main signal adapter board and at least one standby signal adapter board. Therefore, the situation that the display equipment cannot work due to the failure of the display support module can be avoided, and the reliability of the display equipment is improved. It can be understood that, under the condition that the display support modules in the display shooting have backup, if one of the display support modules fails, the display device can switch the display support module corresponding to the backup to continue working, so that the display device continues displaying. Under this condition, the engineering personnel can maintain the demonstration support module of trouble from display device's rear side, and the maintenance work neither can influence meeting place order and meeting place image like this, also can not influence going on of meeting, is favorable to promoting user experience.

Referring to fig. 10 and fig. 11, since a large number of light emitting chips are disposed on the front side of the lamp panel 401, and a large number of driving chips are disposed on the rear side of the lamp panel 401, when the lamp panel 401 is driven by current, a large amount of heat will be generated, and heat dissipation needs to be considered in order to avoid that the high heat environment affects the performance of the light emitting chips and the driving chips. In some examples of the embodiment, a heat conducting material is disposed between the lamp panel 401 and the bottom housing 402, and the heat on the lamp panel 401 can be guided to one side of the bottom housing 402 by using the heat conducting material and dissipated from the bottom housing 402. In some examples, a plurality of heat dissipation fins 4020 are arranged on the surface of the bottom case 402 away from the lamp panel 401, and the surface area of the bottom case 402 is increased by the heat dissipation fins 4020, which is beneficial to improving the heat dissipation efficiency of the bottom case 402.

In order to ensure the heat dissipation efficiency of the bottom case 402, in this embodiment, the surface of the distributing board 403 disposed on the side of the bottom case 402 away from the lamp panel 401 is usually smaller, so as to prevent the distributing board 402 from shielding the heat dissipating fins 4020. In addition, in order to ensure that the module holding portion 414 disposed on the bottom casing 402 can be exposed out of the distributing board 403, in this embodiment, the middle portion of the distributing board 403 is hollowed out, and the module holding portion 414 can pass through the middle portion to be hollowed out and extend out of the distributing board 403.

Among the display device that this embodiment provided, the display module assembly supports the dismouting of both sides around from the center, the rear cover supports from center side rear side dismouting, and simultaneously, it fixes on the center also to adopt the dual operation end fixing piece to show that support the module, so, show that support the module and also support from the dismouting of both sides around the center equally, this has made things convenient for the engineer to maintain each part in the display device under different scenes, the maintenance flexibility and the maintenance efficiency of display device have been promoted, the maintenance work burden has been reduced. In addition, two sets of external interfaces can be arranged on the distributing board of the display module, so that the universality of the display module is enhanced, and the installation efficiency of the display module is improved.
