In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] like Figures 1 to 10 As shown, according to the first aspect of the present application, the present application provides a display module, including a mask 20, a module bottom shell and a lamp board 30 provided with lamp beads 31, the lamp board 30 is installed on the module bottom shell, and the mask 20 covers the outer side of the lamp board 30 to protect the lamp beads 31 on the lamp board 30.

[0032] In this embodiment, the module bottom shell includes a bottom shell body 10 and a protective sheet 40. The protective sheet 40 is arranged on the outside of the bottom shell body 10 to enhance the strength of the module bottom shell and prevent the display module from being damaged due to collision during transportation and actual use. For example, when a collision occurs at the corner of the display module, the corner is damaged, and even the module bottom shell is deformed, making it unusable. This can extend the service life of the display module without the need for additional protective devices, and can effectively reduce the production cost of the LED display.

[0033] In an optional embodiment, the bottom shell body 10 has an upper end surface for installing the lamp board 30, the protective sheet 40 is at least partially higher than the upper end surface of the bottom shell body, and when the protective sheet 40 is arranged around the outside of the bottom shell body, an enclosing structure is formed. The enclosing structure is at least used to constitute an outer frame of the mask 20, which can protect the lamp beads on the lamp board together with the mask 20. There is no need to set an outer frame on the outside of the mask 20. The layout is reasonable, which can reduce the manufacturing cost of the mask 20 while satisfying the protection of the lamp beads 31.

[0034] In an optional embodiment, at least a portion of the protection sheet 40 is higher than or flush with the surface of the lamp bead 31 .

[0035] In an optional embodiment, the protective sheet 40 is a protective sheet made of metal material, and the mask 20 is a mask made of plastic material, that is, when the display module collides in the height direction, the portion of the protective sheet 40 that is higher than or flush with the surface of the lamp beads can play a protective function for the mask 20. At the same time, the strength of the protective sheet 40 is higher than that of the mask 20, and it will not deform like the mask 20, so it will not directly squeeze the lamp beads close to the side of the protective sheet 40, causing damage to the lamp beads. If the protective sheet 40 is made of the same material as the mask 20, it will deform like the mask 20 during a collision, and will directly squeeze the lamp beads 31 close to the side of the protective sheet 40, thereby affecting the lamp beads 31 and causing damage to the lamp beads. Therefore, in the present application, the outer frame of the mask 20 is formed by the protective sheet 40 being higher than or flush with the surface of the lamp beads. Not only does it not need to set an outer frame on the outside of the outer frame to protect the outer lamp beads 31, thereby reducing the manufacturing cost of the mask 20; the protective sheet 40 and the mask 20 are also set to different materials, especially the protective sheet 40 is made of metal material, which can further improve the protection of the lamp beads 31.

[0036] In an optional embodiment, the number of protective sheets 40 is at least one. When there is one protective sheet 40, the protective sheet 40 forms an end-to-end surrounding structure around the outer side of the bottom shell body 10; when there are multiple protective sheets 40, multiple protective sheets 40 are sequentially arranged on the outer side of the bottom shell body 10 to form a surrounding structure. Wherein, whether there is one or more protective sheets 40, the protective sheets 40 have at least a portion that is higher than or flush with the surface of the lamp bead 31, and the portion can protect the lamp bead 31 to prevent the bottom shell of the module from squeezing the lamp bead 31 during collision and squeezing, and does not need to be protected by the outer frame of the mask 20, that is, the outer side of the mask 20 in the present application does not need to be provided with a frame, and the problem of squeezing the lamp bead can also occur during the collision of the display module.

[0037] In an optional embodiment, the protective sheet 40 has a raised extension portion 41 extending along the length direction of one side of the protective sheet 40 . The height of the raised extension portion 41 is higher than or flush with the surface of the lamp bead 31 to protect the lamp bead 31 .

[0038] In an optional embodiment, there are at least three protective sheets 40 , and at least three protective sheets 40 are correspondingly arranged at each corner of the bottom shell body 10 .

[0039] In an optional embodiment, for the convenience of splicing, the display module is usually designed as a rectangular structure. There are four protective sheets 40, all of which are L-shaped structures. The bottom shell body 10 is a rectangular structure. The four protective sheets 40 are respectively arranged at the four corners of the bottom shell body 10 to enhance the strength of the bottom shell body 10 and prevent the corners of the bottom shell body 10 from being damaged or even deformed when a collision occurs, so that the bottom shell of the module cannot be used.

[0040] After adopting the above technical solution, since the display screen or display module is easily damaged by collision during transportation and use, the protective sheet 40 is arranged at the corners of the bottom shell body 10 to enhance the strength of the bottom shell body 10, and prevent the corners of the bottom shell body 10 from being damaged in the event of a collision, or even causing the bottom shell body 10 to be deformed and thus unusable; there is no need to add additional corner protection devices to protect the corners of the display module, which can effectively reduce the production cost of the display screen.

[0041] In an optional embodiment, the four protective sheets 40 are each provided with a first fixing portion, and the bottom shell body 10 is provided with a second fixing portion, so that the four protective sheets 40 can be fixed on the bottom shell body 10 through the cooperation between the first fixing portion and the second fixing portion.

[0042] In an optional embodiment, the module bottom shell includes a connector, the second fixing portion is a locking hole 121 provided on the bottom shell body 10, the first fixing portion is a connecting hole 42 provided on the protective sheet 40, the connector passes through the connecting hole 42 and is connected to the locking hole 121, and is used to detachably install the protective sheet 40 on the bottom shell body 10 to enhance the strength of the module bottom shell. The connector can be a screw, the locking hole is a threaded hole matching the screw, the screw passes through the connecting hole and is threadedly connected to the threaded hole, so that the protective sheet 40 can be fixed in the bottom shell body 10.

[0043] In an optional embodiment, a mounting area 12 having a shape matching that of the protective sheet 40 is provided on the bottom shell body 10, and at least a portion of the mounting area 12 extends to the side of the bottom shell body 10 facing the light board 30. The protective sheet 40 is fixed in the mounting area 12 through a connecting piece passing through the connecting hole 42 and the locking hole 121, so as to enhance the strength of the bottom shell body 10 and prevent the corners of the bottom shell body 10 from being damaged or even deforming the bottom shell of the module when a collision occurs, making it unusable. Among them, since at least a portion of the mounting area 12 extends to the side of the bottom shell body 10 facing the light board 30, the light board 30 can be directly connected to the protective sheet 40 fixed on the mounting area 12, or the outer edge of the light board 30 can fit with the protective sheet 40, and the thickness of the protective sheet 40 is thin enough, so it will not affect the display effect after the display module is spliced.

[0044] In an optional embodiment, the protective sheet 40 has a first protective strip extending in the lateral direction of the bottom shell body 10 and a second protective strip extending in the vertical direction of the bottom shell body 10 , and the first protective strip and the second protective strip are respectively arranged at one of the corners of the bottom shell body 10 .

[0045] In this embodiment, four protective sheets 40 are correspondingly arranged at the four corners of the bottom shell body 10, and there is a small gap or no gap between the two first protective strips or the two second protective strips located on the same side of the bottom shell body 10, so that multiple first protective strips and multiple second protective strips can be connected to each other end to end and form an enclosing structure that surrounds the outside of the mask 20. That is, the present application can reduce the outer frame outside the mask 20 through the cooperation of the protective sheet 40 and the mask 20, and will not cause the problem of squeezing the lamp beads during the collision of the display module.

[0046] In an optional embodiment, the mask 20 includes a brim structure, the height of the brim structure is adapted to the height of the protective sheet 40 protruding from the bottom shell body 10, so that the portion of the protective sheet 40 protruding from the bottom shell body 10 can protect the lamp beads 31 on the lamp board 30 together with the brim structure. There is no need to set an outer frame on the outside of the mask 20. The layout is reasonable, and while ensuring the protection of the lamp beads 31, the manufacturing cost of the mask 20 can be reduced.

[0047] In an optional embodiment, the brim structure includes a first brim 21 and a second brim 22 of different heights, the second protective strip has a protrusion 41 protruding from the bottom shell body 10, the first brim 21, the second brim 22 and the protrusion 41 extend in the lateral direction of the bottom shell body 10, and the height of the protrusion is not higher than the height of the first brim 21 and the second brim 22. In this embodiment, the height of the first brim 21 is greater than the height of the second brim 22, and the height of the protrusion is adapted to the height of the first brim 21. Among them, the function of the first brim 21 is to protect the lamp beads 31 and reduce the impact of sunlight ultraviolet rays / wind and snow on the lamp beads. The function of the second brim 22 is to enhance the contrast of the display screen, and also has the function of enhancing the strength of the mask 20.

[0048] In an optional embodiment, the height of the first protection strip is flush with the height of the bottom shell body 10 .

[0049] In an optional embodiment, the first brim 21 and the second brim 22 are arc-shaped structures at the end away from the light panel 30, which can prevent the protruding brim structure from having edges or other sharp structures, avoid injuries to users, and improve the safety of users when installing and using the display screen mask.

[0050] In an optional embodiment, the mask 20 includes a base plate 25 formed with a brim structure, and the base plate 25 is provided with a plurality of placement holes 24 for placing the lamp beads 31 and arranged at intervals. The brim structure is arranged along a preset direction and located on both sides of the placement holes.

[0051] Exemplarily, a plurality of placement holes 24 are arranged in a rectangular array on the base plate 25 , and a first brim 21 and a second brim 22 are disposed on the base plate 25 and located on both sides of each placement hole 24 in the vertical direction. At the same time, the first brim 21 and the second brim 22 extend in the lateral direction of the base plate 25 .

[0052] After adopting the above technical solution, since the first brim 21 and the second brim 22 are arranged on both sides of the placement hole 24, the light irradiated from the top of the mask 20 can be shielded more, avoiding direct sunlight to the LED, forming reflection, and affecting the viewing effect, and the light displayed by the lamp beads 31 on the mask 20 can be more uniform, which can significantly improve the display effect of the display screen. At the same time, setting the mask on the outside of the light board 30 can enhance the contrast of the display screen and also play a role in waterproofing and dustproofing.

[0053] In an optional embodiment, a serrated structure 23 is provided on the side of the placement hole 24 adjacent to the brim structure, and the extension direction of the serrated structure 23 is perpendicular to the extension direction of the brim structure, and at least part of the structure of the brim structure protrudes from the outside of the serrated structure 23, and at least part of the structure of the serrated structure 23 protrudes from the outside of the brim structure, that is, the outside of the mask 20 is composed of the serrated structure 23 and the brim structure, and the two outer serrated structures 23 and the brim structure can cooperate with the protective sheet 40 to avoid the problem of squeezing the lamp beads during the collision of the display module.

[0054] After adopting the above technical solution, since the bottom plate 25 is provided with the sawtooth structure 23 on both sides of the placement hole 24, the light emitted by the lamp beads 31 can be converged, the contrast and color difference saturation are increased, the reflection is reduced, the focusing effect of the lamp beads 31 is improved, and the glare generation rate is reduced. On the contrary, if the bottom plate 25 is a flat design and the sawtooth structure 23 is not provided on the bottom plate 25, the reflection will be more obvious when viewing, thereby affecting the viewing.

[0055] In an optional embodiment, the extension direction of the first brim 21 and the second brim 22 is perpendicular to the extension direction of the serration 23, and at least part of the structure of the first brim 21 and the second brim 22 protrudes from the outside of the serration 23, and at least part of the structure of the serration 23 protrudes from the outside of the first brim 21 and the second brim 22, that is, the outer edge of the mask 20 is not surrounded by the serration 23 or the first brim 21 and the second brim 22, and at least part of the serration 23 or the first brim 21 and the second brim 22 protrudes a small part to form a part of the placement hole 24, that is, the placement hole 24 has only two sides, one side can be formed by the serration 23, and the other side wall can be formed by the first brim 21 and the second brim 22, and the other two sides of the placement hole 24 can be formed by the protective sheet 40.

[0056] In an optional embodiment, the display module further includes a mask splicing strip 50 , which can be connected between adjacent masks 20 to form the other two side edges of the placement hole 24 .

[0057] Among them, each display screen has multiple display modules, and a display module is formed by splicing multiple masks to form a new mask, and then the new mask is installed on the module light board. However, the mask 20 of the present application does not have an outer frame. When the mask 20 is spliced ​​on the left and right sides of the display module, the mask 20 will produce certain differences at the splicing. In order to ensure the consistency of the mask 20, a mask splicing strip 50 is set at the splicing between two adjacent masks 20, and the mask splicing strip 50 is connected to the mask 20 by a snap-on method.

[0058] In an optional embodiment, a connecting protrusion 54 is provided on the mask splicing strip 50, and a connecting groove 251 is formed at the bottom of the mask 20, so that the mask splicing strip 50 can be positioned and connected to the mask 20 through the cooperation between the connecting protrusion 54 and the connecting groove 251.

[0059] In an optional embodiment, the mask splicing strip 50 is provided with a third brim 51, a third brim 52 and a rib serration 53, the structure of the third brim 51 is the same as that of the first brim 21, the structure of the third brim 52 is the same as that of the second brim 22, and the structure of the rib serration 53 is the same as that of the serration 23, so that the mask splicing strip 50 and the mask 20 can be adapted to form a complete new mask.

[0060] In an optional embodiment, the bottom shell body 10 adopts a stepped design, which includes a first step portion 13, a second step portion 15 and a third step portion 16 which are arranged in sequence along the height. The first step portion 13 protrudes from the second step portion 15 and forms an inclined connecting portion 14. The second step portion 15 protrudes from the third step portion 16, so that the sizes of the multiple accommodating grooves formed in the bottom shell of the module can be increased from bottom to top, so that the lamp board can be accommodated in the first step portion and can form a glue pouring groove for glue pouring with the inner wall of the first step portion, so that waterproof glue can be injected into the glue pouring groove by a glue pouring machine, so that the waterproof glue can form the spacing between the lamp beads, and can cover the lamp feet fixing the lamp beads on the lamp board without covering the entire lamp beads, so as to ensure the luminosity of the lamp beads and the waterproof performance of the display module.

[0061] Exemplarily, the accommodating groove includes a first accommodating groove 11 and a second accommodating groove which are sequentially sunken along the height direction of the bottom shell body 10, the size of the first accommodating groove 11 is adapted to the size of the lamp board 30, the size of the second accommodating groove is smaller than the size of the first accommodating groove 11, and a plurality of reinforcing ribs and a plurality of fixing columns are protruding from the bottom surface of the second accommodating groove toward one side of the first accommodating groove 11, which are used to limit and fix the lamp board 30 in the first accommodating groove 11, and the two inner side walls of the lamp board 30 and the first accommodating groove 11 constitute the bottom surface and side wall of the glue filling groove.

[0062] In the present embodiment, the depth of the first accommodating groove 11 is slightly higher than the thickness of the lamp board 30, so that the waterproof glue injected by the glue filling machine can just cover the lamp feet of the lamp beads on the surface of the lamp board without covering the entire lamp beads, thereby ensuring the luminous intensity of the lamp beads while achieving the effect of waterproof and dustproof protection; in other words, the amount of waterproof glue is set according to the height of the lamp beads on the surface of the lamp board, and lamp beads of different heights have different requirements for the height of the waterproof glue; at the same time, the waterproof glue is laid in the spacing between the lamp beads to cover the lamp feet of the lamp beads on the surface of the lamp board.

[0063] After adopting the above technical solution, since the bottom shell body 10 adopts a stepped design, and an inclined connection portion 14 is formed between the first step portion 13 and the second step portion 15, the inclined connection portion 14 can facilitate the splicing of two adjacent display modules into a curved display screen, making the splicing of the curved display screen smoother and more natural, thereby achieving a better display effect. At the same time, the heat dissipation space increased by the third step portion 16 between the bottom shells of two adjacent modules can be used to carry away the heat generated by the display module with the help of the airflow in the heat dissipation space, achieving a very good heat dissipation effect.

[0064] Specifically, the first step portion 13 can meet the installation requirements of the light board 30, and the size of the third step portion 16 is much smaller than that of the first step portion 13. Therefore, after multiple display modules are spliced ​​into a display screen, the heat dissipation space between the bottom shells of two adjacent modules can be increased, so that the heat generated when the display module is working can be carried away with the help of the airflow in the heat dissipation space, which has a very good heat dissipation effect and can also ensure the display effect after the display modules are spliced. The structure is simple and the design is ingenious.

[0065] In an optional embodiment, the structure of the protective sheet 40 is adapted to the structures of the first step portion 13 , the second step portion 15 and the inclined connection portion 14 , so that the protective sheet 40 can be attached to the first step portion 13 , the second step portion 15 and the inclined connection portion 14 .
