[0035] According to the technical solution of the present embodiment, the LED lamp board 10 includes a substrate 11 and a plurality of lamp beads 12 arranged in an array on the substrate 11, wherein the plurality of lamp beads 12 are used to realize the function of displaying an image of the LED display module, and the bottom shell 20 is arranged on the rear side of the LED lamp board 10 to protect the substrate 11 and the structure arranged on the rear side of the substrate 11, and the mask 30 is arranged on the front side of the LED lamp board 10 to protect the substrate 11 and the plurality of lamp beads 12 arranged on the front side of the substrate 11; the first through hole 111 is arranged on the substrate 11 through and between four adjacent lamp beads 12, and the position of the first through hole 111 can avoid the position of the lamp beads 12, so that the setting of the first through hole 111 will not affect the distribution and operation of the plurality of lamp beads 12, thereby ensuring The display function of the LED display module is proved; the second through hole 21 is arranged on the bottom shell 20, the third through hole 31 is arranged on the mask 30, and the multiple first through holes 111, the multiple second through holes 21 and the multiple third through holes 31 are arranged one by one, so that the corresponding first through holes 111, the second through holes 21 and the third through holes 31 form a light-transmitting channel that can penetrate the front and rear surfaces of the LED display module, so that the viewer can see the rear part of the LED display module through the multiple light-transmitting channels when watching the LED display module, thereby improving the transparency of the LED display module, so that the display content on the front side of the LED display module and the rear part of the LED display module can achieve a display effect that complements each other. Therefore, the technical solution of this embodiment can effectively solve the problem of insufficient transparency of the LED display module in the related art.

[0036] It should be noted that, taking the LED display module mounted on the wall as an example, Figure 2As shown, the "front" used in this article to describe the orientation refers to the direction of the LED display module toward the viewer, and the "rear" refers to the direction of the LED display module away from the viewer. In this embodiment, a plurality of lamp beads 12 are arranged in an array in the form of N rows * M columns (where N and M are both positive integers greater than 0), and "the first through hole 111 is located between four adjacent lamp beads 12" refers to the first through hole 111 being located within the range of a first rectangular structure formed with four adjacent lamp beads 12 as vertices, and the sides of the first rectangular structure are the straight lines where the sides of each of the four lamp beads 12 away from the center point of the first rectangular structure are located.

[0037] like Figure 4 as well as Figure 5 As shown, the cross section of the first through hole 111 is a quadrilateral structure, and each vertex 112 of the quadrilateral structure is located between two adjacent lamp beads 12 of the corresponding four lamp beads 12. Specifically, in this embodiment, the cross section of the first through hole 111 is a second rectangular structure, and the vertex 112 of the second rectangular structure is located between two adjacent lamp beads 12 of the corresponding four lamp beads 12, and each side of the second rectangular structure is close to the vertex of the corresponding lamp bead 12 close to the center point of the first rectangular structure (for example, the side of the upper left corner of the second rectangular structure is close to the vertex of the lower right corner of the lamp bead 12 located at the upper left corner of the first rectangular structure, and the side of the lower right corner of the second rectangular structure is close to the vertex of the upper left corner of the lamp bead 12 located at the lower right corner of the first rectangular structure), so that the second rectangular structure can be larger within the range of the first rectangular structure, thereby making the first through hole 111 larger and easier to process, thereby ensuring the transparency of the LED display module. In addition, in other embodiments not shown in the figure, the cross section of the first through hole can also be a circular structure, an elliptical structure or other special-shaped structures.

[0038] like Figure 4 as well as Figure 5As shown, in the present embodiment, in the length direction of the LED light board 10, the interval between two adjacent first through holes 111 is a first distance, and the interval between two adjacent lamp beads 12 is a second distance, and the first distance is greater than the second distance. Specifically, the "first distance" refers to the distance between the vertices 112 of two adjacent first through holes 111 that are closest to each other in the length direction of the LED light board 10; the "second distance" refers to the distance between the sides of two adjacent lamp beads 12 that are closest to each other in the length direction of the LED light board 10; in the related art, if the distance between the through holes on the light board is too small, there is usually less space on the substrate for wiring, and usually a driver chip is provided for each lamp bead, and then multiple driver chips are connected in series in each column or row, so that If the first distance is greater than the second distance, the number of driver chips will be large, and the manufacturing cost of the LED module will be high. In this embodiment, the first distance is greater than the second distance, so that there is a relatively large distance between the two adjacent first through holes 111, that is, there is a certain size of non-perforated position between the two adjacent first through holes 111, and this position can be used for wire routing. A driver chip is routed through the non-perforated position and then electrically connected to multiple lamp beads 12 respectively, so that the LED display module of this embodiment can be provided with relatively few driver chips, thereby achieving the effect of reducing manufacturing costs. In addition, in the width direction of the LED light board 10, the interval between the two adjacent first through holes 111 is the third distance, and the interval between the two adjacent lamp beads 12 is the fourth distance, and the third distance is greater than the fourth distance. The meaning of "third distance" is similar to that of "first distance", and the meaning of "fourth distance" is similar to that of "second distance", and the effect achieved by "third distance greater than fourth distance" is similar to that achieved by "first distance greater than second distance", which will not be repeated here.

Specifically, the annular rib 24, the enclosure 23 and the front surface of the substrate 11 form a first accommodation space, and the first waterproof layer is located in the first accommodation space to waterproof and seal the front side of the LED light board 10. The first waterproof layer is formed by pouring waterproof glue into the first accommodation space and curing it.

Specifically, the setting position of the glue injection hole 221 on the shell body 22 is located in the area of ​​the shell body 22 corresponding to the installation area 114 of the LED light board 10. In addition, a recessed portion 222 protruding backward is also provided in the area corresponding to the glue injection hole 221 on the shell body 22. When the LED light board 10 and the bottom shell 20 are assembled together, the area of ​​the shell body 22 other than the recessed portion 222 abuts against the substrate 11, and the recessed portion 222 and the rear surface of the substrate 11 are spaced apart and form a second accommodating space. The second waterproof layer is located in the second accommodating space to play a role in waterproofing and sealing the rear side of the LED light board 10. The second waterproof layer is formed by pouring waterproof glue into the second accommodating space and curing it. The waterproof glue can be epoxy resin or the like.
