Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0036] The following will describe in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] As Figures 1 to 8 shown, according to the first aspect of the present application, the present application provides a display module, including a bottom case 10, a lamp board 20 and a face mask 30. The bottom case 10 includes a bottom case body 11 made of a metal material and a support plate 12 made of a plastic material. A bottom case inner cavity 111 is formed in the bottom case body 11. The support plate 12 is disposed in the bottom case inner cavity 111. The lamp board 20 is fixed on the bottom case body 11 and connected to the support plate 12. The face mask 30 is fixed on the support plate 12 to realize the fixed connection of the face mask 30 and the lamp board 20 with the bottom case 10. Among them, since the bottom case body 11 is made of a metal material, it can not only enhance the heat dissipation function of the display module, but also improve the overall strength of the display module. In addition, since most of the connecting screws between the lamp board 20 and the face mask 30 are relatively small in diameter, especially the screw caps exposed on the face mask 30 usually adopt a relatively small diameter structure, and it is difficult to process relatively small threaded holes inside the bottom case body 11 made of a metal material, that is, the processing technology is limited. Therefore, by providing the support plate 12 made of a plastic material in the bottom case inner cavity 111 in the present application, it is convenient to process relatively small threaded holes, realize the fixed connection between the lamp board 20 and the face mask 30, optimize the assembly structure of the display module, will not increase the overall volume of the display module, optimize the assembly structure of the display module, and also achieve a good heat dissipation effect.

[0038] In an optional embodiment, a hollow structure 121 is formed in the support plate 12 to reduce the contact area between the lamp board 20 and the support plate 12. It can not only make the lamp board 20 be in the same horizontal plane and improve the flatness of the display module, but also further improve the heat dissipation effect of the display module, so that the heat generated when the lamp board 20 works can be transferred from the hollow structure 121 to the bottom case body 11, and then be dispersed into the environment through the bottom case body 11 to achieve a good heat dissipation effect. Moreover, it can also play a supporting role for the lamp board 20.

[0039] It should be noted that the support plate 12 can be a structural component directly placed in the bottom case inner cavity 111, or a structural component fixed in the bottom case inner cavity 111. Similarly, the face mask 30 and the lamp board 20 can also be fixed on the bottom case 10 and the support plate 12 by other connection methods, which are not limited in the present application.

[0040] In an alternative embodiment, a first fixing post 112 is provided on the bottom case body 11. The first fixing post 112 extends from the bottom of the inner cavity 111 of the bottom case towards the side of the lamp board 20. The lamp board 20 is fixed on the first fixing post 112, which can not only achieve the fixed connection between the lamp board 20 and the bottom case body 11, but also achieve the fixed connection between the support board 12 and the bottom case body 11, so that the support board 12 can be restricted within the inner cavity 111 of the bottom case. The structure is simple and the installation is convenient.

[0041] In an alternative embodiment, a second fixing post 122 is provided on the support board 12, a limiting hole 23 is provided on the lamp board 20, and a second fixing hole 32 is provided on the mask 30. The position of the second fixing hole 32 corresponds to the positions of the limiting hole 23 and the second fixing post 122, so that the second connecting member 50 can pass through the second fixing hole 32 and the limiting hole 23 in sequence and then be fixedly connected to the second fixing post 122 to fix the mask 30 and the lamp board 20 on the support board 12.

[0042] In an alternative embodiment, a first locking hole 1121 is formed on the first fixing post 112 and a first connecting member 40 is connected to the first locking hole 1121. A first fixing hole 22 is provided on the lamp board 20.

[0043] In an alternative embodiment, a second locking hole 1221 is formed on the second fixing post 122 and a second connecting member 50 is connected to the second locking hole 1221. The second connecting member 50 passes through the second fixing hole 32 and the limiting hole 23 in sequence and then is connected to the second locking hole 1221, so that the mask 30 and the lamp board 20 can be fixed on the second fixing post 122 through the second connecting member 50.

[0044] In an alternative embodiment, a second locking hole 1221 is formed on the second fixing post 122 and a second connecting member 50 is connected to the second locking hole 1221.

Among them, the nut structure 513 is spaced from the snap-in protrusion 512 through the connection structure 511, and the diameter of the connection structure 511 is smaller than the diameters of the nut structure 513 and the snap-in protrusion 512, so that the face mask 30 can be snap-fitted into the connection structure 511 through the second fixing hole 32, and the snap-in protrusion 512 can achieve the fixed connection of the lamp board 20.

[0046] In this embodiment, the nut structure 513 is provided with a guiding inclined surface, and a guiding cavity is formed inside the second fixing hole 32. When the face mask 30 moves along the inner wall of the guiding cavity along the guiding inclined surface during the extrusion process, the second fixing hole 32 can be snap-fitted into the connection structure 511, which is not only beneficial to the assembly of the face mask 30 but also beneficial to the disassembly of the face mask 30.

[0047] In an alternative embodiment, the second connecting member has a threaded structure 52 for threadedly connecting with the second locking hole 1221. The outer diameter of the threaded structure 52 is smaller than the outer diameter of the snap-in protrusion 512, and the outer diameter of the snap-in protrusion 512 is larger than the inner diameter of the limiting hole 23, so that the lamp board 20 can be fixed through the snap-in protrusion 512.

[0048] In an alternative embodiment, the second connecting member has a guiding portion 53. The guiding portion 53 is connected to the front end of the threaded structure 52 and is used to guide the threaded structure 52 to connect to the second locking hole 1221. Among them, the guiding portion 53 is a sharp structure provided at the front end of the threaded structure 52.

[0049] In an alternative embodiment, the material for manufacturing the face mask 30 has a certain elasticity, so that the second fixing hole 32 can be snap-fitted into the snap-in portion 51 under the action of an extrusion force, and at the same time, it is also convenient for the face mask 30 to separate from the snap-in portion 51 when subjected to a disassembly force. The direction of the disassembly force of the face mask 30 is opposite to the direction of the extrusion force when the face mask 30 is snap-fitted into the snap-in portion 51. In an alternative embodiment, the diameter of the second locking hole 1221 is smaller than the diameter of the first locking hole 1121.

[0050] In an alternative embodiment, the diameter of the limiting hole 23 is adapted to the diameter of the second fixing post 122, so that the limiting hole 23 can be penetrated through the second fixing post 122. Among them, the diameter of the second fixing hole 32 is smaller than the diameter of the limiting hole 23.

[0051] In an alternative embodiment, the bottom shell body 11 includes a bottom wall and side walls extending from the periphery of the bottom wall. An abutting platform 113 is formed inside the side walls. An abutting post 123 is provided on the support plate 12. The height of the abutting post 123 is adapted to the height of the abutting platform 113 and is used to support the lamp board 20.

[0052] In an alternative embodiment, the support plate 12 includes a plurality of first ribs 124 and a plurality of second ribs 125 that intersect each other. The plurality of first ribs 124 are spaced apart in a first direction of the inner cavity 111 of the bottom case, and the plurality of second ribs 125 are spaced apart in a second direction of the inner cavity 111 of the bottom case. The first direction is perpendicular to the second direction. Herein, the first direction may be the length direction of the bottom case body 11, and the second direction is the width direction of the bottom case body 11; alternatively, the first direction may be the width direction of the bottom case body 11, and the second direction is the length direction of the bottom case body 11. The present application does not impose any limitations in this regard.

[0053] In an alternative embodiment, a plurality of lamp beads 21 are provided on the lamp board 20, and the mask 30 has a receiving groove 31.
