Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and a light-emitting device. Background Technology

[0002] LED (Light Emitting Diode) electronic displays are a type of display that controls light-emitting diodes. They consist of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels arranged uniformly.

[0003] During the assembly of the display module, a mask needs to be installed on the outside of the LED light panel to protect it. However, related technologies suffer from problems such as poor mask protection and high assembly difficulty. Utility Model Content

[0004] Therefore, it is necessary to provide a display module and a light-emitting device to address the problems of poor protective performance and difficult assembly of face masks.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide a display module, including:

[0007] The bottom shell includes a main body, a plurality of first connecting posts and a plurality of second connecting posts. The main body has a front and a back side that are disposed opposite to each other, and each of the first connecting posts and the second connecting posts is disposed on the front side.

[0008] The light panel has multiple first through holes and multiple second through holes, with each first through hole corresponding to a first connecting post and each second through hole corresponding to a second connecting post.

[0009] The mask has multiple third through holes, each of which corresponds to a second through hole.

[0010] The first connector passes through the first through hole and is locked to the first connecting post;

[0011] The second connector is sequentially passed through the third through hole and the second through hole and then locked to the second connecting post.

[0012] In one embodiment of the first aspect, the second connecting post protrudes relative to the first connecting post, and the end of the second connecting post away from the body passes through the second through hole.

[0013] In one embodiment of the first aspect, the second connecting post protrudes 0.05mm-0.15mm from the surface of the lamp panel.

[0014] In one embodiment of the first aspect, the lamp panel is provided with a plurality of lamp beads at one end away from the bottom shell, and the mask is provided with a plurality of fourth through holes, with each lamp bead embedded in a corresponding fourth through hole.

[0015] In one embodiment of the first aspect, the bottom shell has a wavy cross-section.

[0016] In one embodiment of the first aspect, the display module further includes a handle disposed on the back side and integrally formed with the main body.

[0017] In one embodiment of the first aspect, the display module further includes a mounting bracket disposed on the back side and integrally formed with the main body;

[0018] The connector also has a fifth through hole for threading a safety rope.

[0019] In one embodiment of the first aspect, the display module further includes a pressure lock and a third connector, the third connector being inserted through the pressure lock and locked to the back side of the main body.

[0020] In one embodiment of the first aspect, the mask is provided with a brim that protrudes from the surface of the mask, and each of the third through holes is formed at the brim.

[0021] Secondly, embodiments of this application also provide a light-emitting device, including the display module described in any of the above embodiments.

[0022] Compared to related technologies, the beneficial effects of this application are as follows: This application provides a display module and a light-emitting device. The display module includes a base shell, a lamp board, a faceplate, a first connector, and a second connector. The base shell is provided with a first connecting post and a second connecting post. The lamp board has a first through hole and a second through hole, and the faceplate has a third through hole. The first connector passes through the first through hole and locks with the first connecting post to install the lamp board onto the base shell. The second connector passes through the third through hole and the second through hole in sequence and locks with the second connecting post to install the faceplate onto the base shell. In this way, the lamp board and the faceplate are independently fixed to the base shell, and their structures are relatively independent. This design not only improves the protective performance but also allows the faceplate to be made thicker and the brim higher, further enhancing the protection of the LED chips. At the same time, it avoids the dependence of the faceplate's fixation on the lamp board, reduces the risk of damage to the lamp board due to external forces, and reduces the assembly difficulty.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] In related technologies, LED display module covers have two installation methods. Option 1: The cover is clipped onto the LED chips on the LED board. However, to accommodate this clip structure, the cover needs to be made thin overall with a low brim, resulting in poor protective performance and susceptibility to damage to the LED board upon impact. Option 2: The cover is fixed to the LED board PCB (Printed Circuit Board) with screws. However, the PCB is made of fiberglass, which is relatively rigid. Excessive screw torque can cause the PCB or screws to break, while insufficient torque will prevent proper fixation. This requires extremely high precision in the PCB screw hole dimensions, making assembly difficult.

[0041] See Figure 1 As shown, to improve the above-mentioned problems, embodiments of this application provide a display module 100, which includes a base shell 110, a lamp panel 120, a face mask 130, a first connector 140, and a second connector 150. The base shell 110 serves as the mounting carrier for the lamp panel 120 and the face mask 130. The lamp panel 120 is independently mounted on the base shell 110 via the first connector 140. The face mask 130 is directly connected to the base shell 110 via the second connector 150, and is mounted on the back side 115 of the lamp panel 120 and one side of the base shell 110 to protect the lamp panel 120.

[0042] Compared to related technologies, the display module 100 provided in this application embodiment allows both the lamp panel 120 and the faceplate 130 to be independently fixed to the base shell 110, with relatively independent structures. This not only improves protective performance but also allows the faceplate 130 to be made thicker and the brim 133 to be higher, further enhancing the protection of the LED beads 123. At the same time, it avoids the dependence of the faceplate 130 on the lamp panel 120 for fixation, reducing the risk of damage to the lamp panel 120 due to external forces.

[0043] Continue reading Figure 2 As shown, exemplarily, the bottom shell 110 includes a main body 111, a plurality of first connecting posts 112, and a plurality of second connecting posts 113. The main body 111 has a front side 114 and a back side 115 disposed opposite to each other, and each of the first connecting posts 112 and the second connecting posts 113 is disposed on the front side 114.

[0044] Understandably, the front side 114 of the main body 111 is used to mount the lamp panel 120 and the mask 130 so that the lamp panel 120 can emit light from the front side 114 to form the light-emitting surface of the display module 100. The back side 115 of the main body 111 is the backlight surface of the display module 100, which can be mounted on a wall or a working bracket, and can also be used as a load-bearing surface for handling and transfer.

[0045] Continue reading Figure 3 As shown, for example, the lamp panel 120 has multiple first through holes 121 and multiple second through holes 122. The first through holes 121 correspond one-to-one with the first connecting posts 112, and the second through holes 122 correspond one-to-one with the second connecting posts 113. The first connecting posts 112 have holes for connecting and engaging with the first connecting member 140, so that the first connecting member 140 passes through the first through hole 121 and locks with the first connecting post 112, thereby independently fixing the lamp panel 120 to the base shell 110.

[0046] Understandably, the first connector 140 is a screw, and the opening in the first connecting post 112 is a threaded hole. After the first connector 140 passes through the first through hole 121, it is locked with the threaded hole of the first connecting post 112. In other embodiments, the first connector 140 may also be a pin or rivet, etc., and after passing through the first through hole 121, it is engaged and fixed with the hole in the first connecting post 112, all of which can meet the fixing requirements of this application.

[0047] Continue reading Figure 4 and Figure 5 As shown, for example, the face mask 130 has multiple third through holes 131, each corresponding to a second through hole 122. The second connecting post 113 has holes for connecting and engaging with the second connecting member 150, so that the second connecting member 150 passes through the third through hole 131 and the second through hole 122 in sequence and is locked with the second connecting post 113, thereby independently fixing the face mask 130 to the base shell 110 and protecting the lamp panel 120.

[0048] Thus, during the installation of the face shield 130, the second connector 150 only passes through the second through hole 122 and does not directly contact the lamp panel 120, thereby avoiding the possibility of the lamp panel 120 breaking under stress. At the same time, the overall thickness of the face shield 130 does not need to be reduced, thus improving the overall protective performance.

[0049] Understandably, the second connector 150 is a screw, and the opening in the second connecting post 113 is a threaded hole. The second connector 150 passes through the third through hole 131 and the second through hole 122 in sequence and is then locked with the threaded hole of the second connecting post 113. In other embodiments, the second connector 150 may also be a pin or a rivet, etc., and be engaged and fixed with the hole in the second connecting post 113 after passing through the third through hole 131 and the second through hole 122, all of which can meet the fixing requirements of this application.

[0050] For ease of understanding, the first connector 140 and the second connector 150 in the embodiments of this application are both illustrated using screws as examples.

[0051] In some embodiments, the second connecting post 113 protrudes relative to the first connecting post 112, and one end of the second connecting post 113 away from the main body 111 passes through the second through hole 122.

[0052] For example, the first connecting post 112 is slightly higher than the front surface 114 of the base shell 110, so that it can extend into the first through hole 121 of the lamp panel 120, but does not protrude from the surface of the lamp panel 120, so as to avoid interfering with the installation of the cover 130. In this way, the first connector 140 is directly locked to the first connecting post 112 without contacting the hole wall of the first through hole 121. While fixing the lamp panel 120 to the base shell 110, the force applied to the lamp panel 120 is reduced, thereby improving the service life of the lamp panel 120.

[0053] Furthermore, the second connecting post 113 is longer than the first connecting post 112, so it can pass through the second through hole 122 of the lamp plate 120 and extend into the third through hole 131 of the mask 130. In this way, the second connecting piece 150 only needs to be directly locked to the second connecting post 113 to fix the mask 130 to the base shell 110 and restrict the lamp plate 120 between the base shell 110 and the mask 130, thus protecting the lamp plate 120. Moreover, no force needs to be applied to the lamp plate 120 during installation, further avoiding stress damage to the lamp plate 120.

[0054] In some embodiments, the second connecting post 113 protrudes 0.05mm-0.15mm from the surface of the lamp panel 120.

[0055] For example, the height of the second connecting post 113 protruding from the surface of the lamp plate 120 can be 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.10mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, etc., and can be reasonably selected according to the thickness of the lamp plate 120 and the mask 130, so as to satisfy the requirement that the second connecting post 113 protrudes from the surface of the lamp plate 120 and facilitates connection with the second connecting member 150.

[0056] See again Figure 3 and Figure 5 As shown, in some embodiments, the lamp panel 120 is provided with a plurality of lamp beads 123 at one end away from the bottom shell 110, and the mask 130 is provided with a plurality of fourth through holes 132, with each lamp bead 123 being embedded in a corresponding fourth through hole 132.

[0057] For example, the lamp bead 123 is an LED lamp, and the fourth through hole 132 is correspondingly configured to be adapted to the lamp bead 123 so that the lamp bead 123 can be embedded in the fourth through hole 132 and exposed on the outside of the mask 130 to meet the light-emitting operation.

[0058] Understandably, when the LED bead 123 has a circular structure, the fourth through hole 132 is correspondingly set to a circular structure; when the LED bead 123 has a rectangular structure, the fourth through hole 132 is correspondingly set to a rectangular structure. This satisfies the protective requirements of the faceplate 130 for the LED bead 123 and improves the overall aesthetics of the display module 100.

[0059] In some embodiments, the mask 130 is provided with a brim 133, which protrudes from the surface of the mask 130, and each third through hole 131 is provided at the brim 133.

[0060] For example, each LED bead 123 has a cap 133 on both sides, which protrudes from the surface of the faceplate 130 to protect the LED bead 123. When it comes into contact with a foreign object, the cap 133 will make contact with it first, thereby preventing the LED bead 123 from being damaged by the impact. At the same time, the third through hole 131 is set at the cap 133, where the thickness is greater, thereby improving the locking strength of the screw and also partially covering the screw, improving the appearance.

[0061] See Figure 4 As shown, it can be understood that the width direction of the display module 100 is taken as the first direction, the length direction is taken as the second direction, and the brim 133 is set parallel to the first direction.

[0062] Continue reading Figure 6 As shown, in some embodiments, the display module 100 also includes a handle 180, which is disposed on the back 115 and is integrally formed with the main body 111.

[0063] For example, the handle 180 is directly integrated into the design of the base shell 110, and is integrally injection molded with the base shell 110 through an injection molding process. In this way, the production and assembly of separate accessories are eliminated, significantly reducing production costs while improving structural stability.

[0064] Continue reading Figure 7 As shown, in some embodiments, the display module 100 further includes a mounting bracket 190, which is disposed on the back surface 115 and is integrally formed with the main body 111. The mounting bracket 190 also has a fifth through hole 191 for threading a safety rope.

[0065] For example, the mounting bracket 190 is also integrated into the design of the base shell 110, and is integrally injection molded with the base shell 110. This further reduces production costs and improves structural stability. By binding the installation rope to the mounting bracket 190, a certain degree of protection can be provided during the installation of the display module 100, preventing the display module 100 from falling and being damaged.

[0066] In some embodiments, the display module 100 further includes a pressure lock 160 and a third connector 170, the third connector 170 being inserted through the pressure lock 160 and then locked to the back surface 115 of the main body 111.

[0067] For example, the third connector 170 is a screw, which passes through the hole in the press-lock 160 and locks itself onto the back surface 115 of the base housing 110 to fix the press-lock 160 to the base housing 110. The press-lock 160 enables quick installation and fixation of the module, quick disassembly, and improves the maintenance efficiency of the module.

[0068] Continue reading Figure 8 As shown, in some embodiments, the bottom shell 110 has a wavy cross-section.

[0069] For example, the bottom shell 110 has a wave-shaped cross-section along the first direction. The mechanical properties of the wave structure are used to greatly improve the overall strength of the bottom shell 110 and enhance the impact resistance and deformation resistance of the display module 100.

[0070] Embodiments of this application also provide a light-emitting device, including the display module 100 in any of the above embodiments.

[0071] For example, the light-emitting device may be a billboard, television, projector, information desk, etc., and there are no specific limitations. Any light-emitting device that uses the display module 100 provided in the embodiments of this application should fall within the protection scope of this application.

[0072] This embodiment has the display module 100 of any of the above embodiments, and therefore has all the beneficial effects of the display module 100 of any of the above embodiments, which will not be described in detail here.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
