DETAILED DESCRIPTION

[0031] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0032] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are shown in great detail. Of course, they are merely examples and are presented to illustrate the application. The purpose is not to limit the application. In addition, reference numerals can be repeated in different examples in the present application. Such repetition is for the purpose of simplicity and clarity and does not indicate any relationship between the various embodiments and / or settings discussed.

[0033] For the convenience of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0034] As Figure 1 and Figure 8 shown, the first aspect, the embodiments of the present application provides a backlight assembly, applied to display module, display module includes display assembly, comprising: light emitting mechanism 10, mounting seat 20 and moisture-proof mechanism 30; The mounting seat 20 is provided with mounting position 21, and the mounting seat 20 is connected on the display assembly;Moisture-proof mechanism 30 includes moisture-proof structure 31 and assembly structure 32, light emitting mechanism 10 and moisture-proof structure 31 are fixedly connected, assembly structure 32 is arranged around moisture-proof structure 31, and moisture-proof mechanism 30 is detachably connected in mounting position 21 through assembly structure 32.Through the above-mentioned setting, the detachable connection of moisture-proof mechanism 30 and display assembly is realized, and light emitting mechanism 10 and moisture-proof structure 31 are fixedly connected, thereby realizing the detachable installation of the whole backlight assembly.Coupled with the setting of moisture-proof structure 31, the waterproof of backlight assembly can be effectively realized, that is, the backlight assembly meets the portable disassembly on the one hand, and the moisture-proof mechanism added on the other hand meets the waterproof demand of backlight assembly.The mounting seat 20 is used for connecting the backlight assembly and the display assembly, plays a connecting role, and can also be a constituent part of the display assembly, which is used for the installation and connection of the display assembly when the backlight assembly is not needed.

[0035] It should be noted that the setting of moisture-proof mechanism 30 can be used to dry the internal environment of display device, absorb water vapor, or collect water vapor inside the display device and discharge it outward for continuous drying operation.Such setting can make the display device provide power supply or heating device when working, so that water vapor evaporates and is discharged, and stores water vapor through moisture-proof mechanism 30 in the non-working state, so as to achieve the daily protection effect, which is beneficial to the drying of internal electrical components of the display device, so as to increase the actual application time of the display device and effectively prolong its service life.

[0036] As Figure 1 and Figure 8 shown, in the technical scheme of the embodiment, the moisture-proof structure 31 includes first plate body 311 and second plate body 312, and the light emitting mechanism 10 is fixedly connected on the first plate body 311.The first plate body 311 is provided with first through hole 3111, and the second plate body 312 is provided with second through hole 3121, and the first through hole 3111 and the second through hole 3121 are both provided with semi-permeable membrane 40.Through the setting of semi-permeable membrane 40 at the position of the two through holes, the water vapor in the moisture-proof structure 31 can flow in the specified direction, which makes the water vapor flow only towards the area outside the backlight assembly, and the external water vapor cannot enter the inside of the backlight assembly through the two through holes, which can effectively dry the effect and reduce the entry of water vapor.

[0037] It should be noted that the semi-permeable membrane 40 can be implemented by DuPont paper to realize one-way flow of water vapor. The semi-permeable membrane 40 can be directly attached, and the semi-permeable membrane 40 needs to completely cover the first through hole 3111 or the second through hole 3121, for example Figure 3 and Figure 4 As shown in the figures, the first through hole 3111 and the second through hole 3121 are multiple and have a certain arrangement and combination order. A single semi-permeable membrane 40 needs to completely cover a certain range of first through holes 3111 or second through holes 3121. Such a setting can adapt to smaller caliber first through holes 3111 and second through holes 3121 to reduce the flow of water vapor, and on the other hand, larger semi-permeable membranes 40 are beneficial to attachment and assembly, compact structure, and higher assembly efficiency.

[0038] As shown in the figures Figure 5 and Figure 6 In the technical solution of the embodiment, a functional layer 313 is arranged between the first plate body 311 and the second plate body 312, and the functional layer 313 is provided with a drying component. The functional layer 313 is arranged to process part of the water vapor entering between the first plate body 311 and the second plate body 312. The drying component can absorb and discharge water vapor in different environments and conditions. In combination with the arrangement of the semi-permeable membrane 40, the water vapor treatment effect is better.

[0039] As shown in the figures Figure 5 and Figure 6 In the technical solution of the embodiment, the drying component includes a heat conduction structure 3131 and a heat dissipation plate body. The heat conduction structure 3131 is fixedly connected to the first plate body 311, and the heat dissipation plate body is fixedly installed on the second plate body 312. The heat dissipation plate body is in contact with the side of the heat conduction structure 3131 away from the first plate body 311. The heat conduction structure 3131 and the heat dissipation plate body are arranged to utilize part of the heat generated during the use of the backlight assembly and the display device for evaporation or sublimation of water vapor. Such an arrangement allows part of the droplets or water vapor to remain in a gaseous state, increasing the volume and thus allowing more water vapor to pass through the semi-permeable membrane 40 and be discharged outward. Such an arrangement utilizes the heat generated during the operation of the display device, utilizes energy, accelerates the evaporation and discharge of water vapor, and effectively conducts heat from the heat generating part of the display device, which is beneficial to heat dissipation of the display device and improves the performance of the display device. In an alternative embodiment, the heat dissipation plate body can be a copper plate or a copper foil, which is attached or directly formed on the side of the second plate body 312 facing the first plate body 311. The heat conduction structure 3131 can also be made of metal materials with high heat conduction and heat dissipation functions, which can improve the efficiency of heat conduction and achieve better cooling and exhaust effects. The heat conduction structure 3131 can also be made of graphite carbon layer, which can also achieve good heat conduction effect.

[0040] As Figure 5 to Figure 7 shown in the technical scheme of the embodiment, the heat-conducting structure 3131 is mesh-shaped, a first containing groove 3133 is formed in the functional layer 313, and the water-absorbing material 3136 is arranged in the first containing groove 3133. The mesh-shaped heat-conducting structure 3131 is beneficial to increasing the area for exchanging heat with air or other substances, thereby improving the heat exchange efficiency. The water-absorbing material arranged in the first containing groove 3133 can realize the functional effect of the functional layer 313, has the function of absorbing water vapor, and such an arrangement can absorb the water vapor by the water-absorbing material 3136 when the water vapor enters the functional layer 313, that is, enters between the first plate body 311 and the second plate body 312, so that more water vapor can be contained, and better drying effect can be achieved, and meanwhile, the water-absorbing material can absorb the water vapor in the display device well during the process of stopping and starting in daily life.

[0041] It should be noted that in alternative embodiments, the water-absorbing material 3136 can be silica gel desiccant, quicklime, activated carbon or other materials having certain adsorption effect and not having irreversible reaction with water vapor, so that the water vapor can overflow from the position of the semi-permeable membrane 40 after the display device is started to a certain extent.

[0042] As Figure 5 shown in the technical scheme of the embodiment, the heat-conducting structure 3131 and the functional layer 313 form a second containing groove 3134, the first containing groove 3133 and the second containing groove 3134 are communicated, and the filter structure 3135 is arranged between the first containing groove 3133 and the second containing groove 3134. The second containing groove 3134 is arranged for the water vapor to pass through directly, a certain space is arranged in the functional layer 313, the water vapor can be contained in a larger amount, and the water vapor has a certain delay space when it is heated and expanded, so that the entire moisture-proof structure 31 will not be expanded, more first through holes 3111 and second through holes 3121 can be arranged, so that the water vapor outlet can be arranged when the water vapor is more, and the drying effect is more beneficial. The filter structure 3135 can prevent the water-absorbing material 3136 of the water absorber from passing through the communicated position, so that the leakage can be avoided.

[0043] As Figure 1As shown, in the technical scheme of the embodiment, the assembly structure 32 is made of magnetic material or magnetically attractable material, the first plate body 311, the second plate body 312 and the assembly structure 32 are fixedly connected through glue, and the mounting position 21 is provided with a magnetic attraction component corresponding to the assembly structure 32. Such a setting realizes the detachable installation of the moisture-proof mechanism 30, has compact structure and convenient assembly. The magnetic attraction mode has intuitive cooperation effect, the material preparation and selection are more, and the reliability is strong. When assembling the backlight assembly, other components can be set according to actual needs, which has stronger plasticity and more flexible design.

[0044] It should be noted that the first plate body 311, the second plate body 312 and the assembly structure 32 are fixedly connected through glue. On the one hand, the glue connection can compensate for the space distance of the functional layer 313 around the side, play a sealing role, and also avoid the connection between the first plate body 311 and the second plate body 312 from having a leak position, causing external moisture to enter or internal moisture to escape. In addition, the assembly structure 32 around the setting makes the cooperation between the moisture-proof structure 31 and the assembly structure 32 more compact, the range of glue wrapping is larger, and thus better sealing effect and connection effect are realized, and the structure is more stable.

[0045] As shown in the figure, Figure 2 In the technical scheme of the embodiment, the mounting seat 20 is also provided with a limiting column 22, which is arranged around the frame diagram respectively, and is used for limiting the circumferential freedom degree of the moisture-proof mechanism 30. Such a setting can avoid considering the circumferential size setting of the moisture-proof mechanism 30, and the assembly structure 32 can satisfy the connection with the mounting seat 20. At the same time, the circumferential freedom degree of the moisture-proof mechanism 30 can avoid the shaking between the mounting seat 20 and the moisture-proof mechanism 30 when the magnetic attraction effect is not obvious or weakened, and play a role in limiting the backlight assembly or even the display assembly.

[0046] As shown in the figure, Figure 8 As shown in the figure, the light emitting mechanism 10 is provided with a breathable hole 11 corresponding to the first through hole 3111, the first through hole 3111 is communicated with the breathable hole 11, and the semi-permeable membrane 40 is arranged on the side of the first through hole 3111 away from the breathable hole 11. The breathable hole 11 of the light emitting mechanism 10 is arranged to communicate the first through hole 3111, plays a role in guiding the moisture inside the display device to enter, and can take away part of the heat of the light emitting mechanism 10 in the process of moisture entering, on the one hand, can cool down, on the other hand, can take the heat into the moisture-proof mechanism 30 and transfer to other moisture, and thus improve the moisture removal effect. It should be noted that the arrangement of the breathable hole 11 on the light emitting mechanism 10 can be arranged according to actual needs, including the appearance and the setting of the moisture entering line.

[0047] It should be noted that the first plate body 311 and the second plate body 312 are made of glass material, which is easy to obtain and process, and is suitable for use in a backlight assembly. The side of the first plate body 311 away from the light emitting mechanism 10 is provided with a dark color coating, specifically black. Such a setting is mainly used to prevent light leakage on the back side of the backlight assembly during light emission. It also blocks light from the beginning position and reduces the impact of light propagation on the remaining display image. Specifically, black ink can be used for full-face printing. The light emitting mechanism 10 is fixedly connected to the first plate body 311 through the connecting layer 50. The connecting layer 50 can be double-sided adhesive or a connecting film formed by glue. The via hole 51 corresponding to the first through hole 3111 and the air hole 11 is provided on the connecting layer 50 to facilitate the communication between the outside and the moisture-proof mechanism 30.

[0048] The embodiment of the present application mainly solves the problem that in the prior art, when a Mini LED display is used outdoors, the inside is easily invaded by water vapor, causing damage to internal electrical components and other fragile components such as lamp panels. Current lamp panels are attached to the back plate (mounting seat 21), and the back plate and the display panel are fixedly installed, which is not conducive to disassembly and replacement. When the display device is used outdoors, its service life is severely limited.

[0049] To solve the above problems, the embodiment of the present application provides a backlight assembly which can be used in the detachable connection of a display module and a display assembly. The main idea is to provide a hollow mounting position 21 in the inside of the mounting seat 20, and to provide a limiting column 22 around the mounting seat 20. The detachable connection between the mounting seat 20 and the display assembly and the magnetic detachable connection between the assembly structure 32 of the moisture-proof mechanism 30 and the mounting seat 20 realize the detachable connection between the moisture-proof mechanism 30 and the display assembly. On the one hand, it can meet the demand of simple disassembly and replacement, and on the other hand, it can meet the demand of absorbing water vapor. The specific idea also includes: the first plate body 311 and the second plate body 312 are provided with a functional layer 313 therebetween. When the display device is in the shutdown state, the functional layer 313 can absorb the internal water vapor through the internal water absorbing material 3136. When the display device is working, the water vapor can be heated and evaporated through the heat dissipation. Specifically, a silica gel desiccant can be used to achieve the effect of absorbing water vapor at room temperature and heating water vapor to evaporate.

[0050] Specifically, in the technical solution of the embodiment of the present application, a backlight assembly with a detachable function is provided, which can effectively solve the problem of water vapor invasion in the display assembly and the display device, and also realize the replacement of the lamp panel of the backlight assembly at any time.

[0051] The middle part of the mounting seat 20 is hollow to avoid the lamp panel, and the limiting column 22 is provided around the back of the back plate, thereby realizing the detachable connection of the backlight assembly and the detachable connection between the backlight assembly and the display assembly.

[0052] The moisture-proof mechanism 30 is specifically divided into three parts: a first plate body 311, a second plate body 312, and a functional layer 313 in the middle.

[0054] The functional layer 313 in the middle: through the assembly column 3112 provided on the first plate body 311, the heat conduction structure 3131 of the functional layer can be correspondingly assembled, and the height of part of the assembly column 3112 is exposed to ensure the gap between the functional layers. The heat conduction structure 3131 is provided in a pattern of a graphite carbon layer, realizing heat conduction. The first accommodating groove 3133 formed by the heat conduction structure 3131 is provided with silica gel desiccant to absorb water vapor. Meanwhile, filter screens are arranged at both ends of the first accommodating groove 3133 to prevent the silica gel desiccant from liquefying after absorbing water vapor, causing leakage. The entire functional layer 313 is fixed on the first plate body 311.

[0055] The second plate body 312: in communication with the external environment, a heat dissipation structure is laid flat on the inner side close to the first plate body 311, specifically a copper plate, realizing uniform heat dissipation. Meanwhile, a second through hole 3121 is formed above the silica gel desiccant corresponding to the second plate body 312. The second through hole 3121 is also provided with a semi-permeable membrane, specifically DuPont paper, realizing one-way transmission of water vapor outward, avoiding liquid backflow and reverse intrusion.

[0056] The first plate body 311 and the second plate body 312 are connected by using glue liquid around the periphery, and a ring of assembly structure is arranged around the periphery. The assembly structure adopts a strong magnet to realize magnetic connection of the entire moisture-proof mechanism 30 and the mounting seat 20.

[0057] The light-emitting mechanism 10 is provided with a corresponding air hole 11 at the first through hole 3111 of the first plate body 311, and is connected with the moisture-proof mechanism 30 by using adhesive tape.
