[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 5 As shown, applying the technical solution of this embodiment, the lamp board assembly includes: a first circuit board 10, a plurality of lamp beads 20 and a first waterproof layer 30. The first circuit board 10 has a lateral direction L1 perpendicular to the viewing direction and a depth direction L2 parallel to the viewing direction. The plurality of lamp beads 20 are arranged on the side wall of the first circuit board 10 in the lateral direction L1 and are electrically connected to the first circuit board 10. The first waterproof layer 30 is coated outside the first circuit board 10 and the lamp beads 20, and the first waterproof layer 30 is made of a transparent material.

[0034] In this way, the lamp beads 20 are arranged on one side of the first circuit board 10 perpendicular to the viewing direction, so that the observer's line of sight can penetrate the front surface and the rear surface of the lamp beads 20 along the viewing direction, reducing the shielding of the lamp beads 20 by the first circuit board 10 along the viewing direction, so as to improve the transparency and permeability of the transparent LED display. The first waterproof layer 30 is coated on the outside of the first circuit board 10 and the lamp beads 20. The first waterproof layer 30 is made of a transparent material to facilitate the observer to observe the lamp beads 20. The first waterproof layer 30 can be coated at the connection between the first circuit board 10 and the lamp beads 20 to waterproof the first circuit board 10 and the lamp beads 20, so that when the transparent LED display is used outdoors, it is difficult for rainwater to penetrate the first waterproof layer 30 and enter between the lamp beads 20 and the first circuit board 10, so that the electrical connection between the lamp beads 20 and the first circuit board 10 is more stable and reliable, and the display effect of the display module is also better. Therefore, the technical solution of this embodiment effectively solves the problem that the waterproof ability of the display module in the related art is poor and it is easy to affect the display effect of the display module.

[0035] In this embodiment, the thickness of the first circuit board 10 in the transverse direction L1 is less than the width of the first circuit board 10 in the depth direction L2, so that the first circuit board 10 can better avoid the viewer's line of sight, thereby improving the transparency and permeability of the transparent LED display. The first waterproof layer 30 is made of epoxy resin.

[0036] like Figures 1 to 5As shown, the light board assembly also includes a transmission member 40, the first end of the transmission member 40 extends into the first waterproof layer 30 and is electrically connected to the first circuit board 10, and the second end of the transmission member 40 extends out of the first waterproof layer 30. The arrangement of the transmission member 40 facilitates the electrical connection of the circuit board with an external power supply member or signal member. The first end of the transmission member 40 extends into the first waterproof layer 30, so that the first waterproof layer 30 can waterproof the contact position between the first end of the transmission member 40 and the first circuit board 10, reducing the possibility of rainwater entering between the transmission member 40 and the first circuit board 10, so as to improve the stability of the transmission member 40 and the first circuit board 10 when they are electrically connected.

[0037] In this embodiment, the transmission element 40 can transmit power and signal data to the first circuit board 10 to facilitate the normal lighting of the lamp bead 20.

[0038] like Figures 1 to 5 As shown, the lamp bead 20 is located on the first side of the first circuit board 10 in the depth direction L2, and the transmission member 40 is located on the second side of the first circuit board 10 in the depth direction L2. In this way, the lamp bead 20 can be located on the side close to the observer, and the first circuit board 10 is located on the side far away from the observer, so that the observer can observe the lamp bead 20, and the existence of the transmission member 40 is also weakened, thereby further improving the transparency and permeability of the transparent LED display.

[0039] The present application also provides a display module, which includes: a rear housing 60, a second circuit board 50 and a plurality of light board assemblies. The second circuit board 50 is disposed in the rear housing 60. The plurality of light board assemblies are electrically connected to the second circuit board 50, and the light board assembly is the above-mentioned light board assembly. Since the above-mentioned light board assembly can solve the problem that the waterproof ability of the display module in the related art is poor and easily affects the display effect of the display module, the display module having the light board assembly can solve the same technical problem.

[0040] In this embodiment, the transmission member 40 has a plurality of connection legs disposed toward the second circuit board 50, and the second circuit board 50 is provided with a plurality of connection holes, into which the connection legs are inserted. The connection legs of the transmission member 40 are welded and connected to the second circuit board 50, so that the connection between the transmission member 40 and the second circuit board 50 is more stable and reliable.

[0041] like Figures 1 to 6As shown, the rear shell 60 is provided with a receiving cavity 64 for receiving the second circuit board 50 and a positioning groove 65 communicating with the receiving cavity 64, and the first waterproof layer 30 of the lamp board assembly is located in the positioning groove 65. The rear shell 60 has a simple structure and is easy to process. The setting of the receiving cavity 64 can accommodate the second circuit board 50 to reduce the possibility of rainwater contacting the second circuit board 50. The setting of the positioning groove 65 facilitates the embedding of the first waterproof layer 30 and the lamp beads 20 and the first circuit board 10 in the first waterproof layer 30 into the rear shell 60, so that the setting and fixing of the first waterproof layer 30 on the rear shell 60 are more convenient and reliable.

[0042] like Figures 1 to 6 As shown, a second waterproof layer is provided between the positioning groove 65 and the first waterproof layer 30. The provision of the second waterproof layer reduces the possibility of rainwater entering the accommodation cavity 64 from between the positioning groove 65 and the first waterproof layer 30, and reduces the possibility of the second circuit board 50 in the accommodation cavity 64 contacting with rainwater, so that the electrical connection between the second circuit board 50 and the light board assembly is more stable and reliable.

[0043] like Figures 1 to 6 As shown, the positioning groove 65 includes a first positioning groove 651 and a second positioning groove 652 respectively arranged on two opposite side walls of the rear shell 60, and the first positioning groove 651 and the second positioning groove 652 are arranged correspondingly and are multiple. Each first waterproof layer 30 is located in a first positioning groove 651 and a second positioning groove 652 corresponding to the first positioning groove 651. The arrangement of the first positioning groove 651 and the second positioning groove 652 makes the positioning and fixation of the first waterproof layer 30 in the positioning groove 65 more stable and reliable, so that multiple light panel assemblies can be better spaced and connected to the rear shell 60.

[0044] In this embodiment, the distance between two adjacent first positioning grooves 651 is equal, and the distance between two adjacent second positioning grooves 652 is equal.

[0045] like Figures 1 to 5 As shown, the display module also includes a sealing ring 62.

The provision of the plug 51 facilitates the plug-in matching of the second circuit board 50 with an external power supply or signal component. The provision of the avoidance hole 61 enables the plug 51 to pass through the rear shell 60. The sealing ring 62 is arranged outside the avoidance hole 61 and is located on the side of the rear shell 60 facing away from the first circuit board 10. The provision of the sealing ring 62 enables the external power supply or signal component to be sealed with the sealing ring 62 when the plug 51 is plugged in with the external power supply or signal component, so as to reduce the possibility of rainwater entering the rear shell 60 from the avoidance hole 61.

[0046] In this embodiment, the plug 51 is used to receive the power and signals sent by the control box of the LED display screen, and then transmit the power and signals sent by the control box of the LED display screen to the lamp board assembly through the second circuit board 50, so that the lamp beads 20 can display corresponding images and pictures as required.

[0047] like Figures 1 to 5 As shown, the first circuit board 10 of the light board assembly is perpendicular to the second circuit board 50, so as to further reduce the projection area of ​​the first circuit board 10 in the viewing direction, reduce the weakening of the first circuit board 10, and further improve the transparency and permeability of the transparent LED display. In this embodiment, the second circuit board 50 is perpendicular to the viewing direction.

[0048] like Figures 1 to 5 As shown, the display module further includes a magnetic member 63, which is disposed on the side of the rear housing 60 away from the first circuit board 10. The arrangement of the magnetic member 63 facilitates the magnetic attraction cooperation between the rear housing 60 and the external device, so as to facilitate the detachable connection between the rear housing 60 and the external device, making the installation of the rear housing 60 more convenient, and also facilitating the front and rear maintenance of the display module. The use of tools is reduced, and the work efficiency of the operator is further improved.

[0049] In this embodiment, the display module further includes a fastener, and the second circuit board 50 is fixedly connected to the rear housing 60 by the fastener. The second circuit board 50 is provided with a through hole for the fastener to pass through, and the rear housing 60 is provided with a connecting column that cooperates with the fastener. The fastener is a screw, and the connecting column is provided with an internal threaded hole that cooperates with the external thread of the screw. The screw passes through the through hole and extends into the internal threaded hole on the connecting column, so that the second circuit board 50 is fixedly connected to the rear housing 60.

[0050] In this embodiment, electronic components are also disposed on the first circuit board 10 , and the electronic components are controlled and connected with the lamp beads 20 so that the lamp beads 20 can emit light as required.

[0051] In this embodiment, there are multiple first circuit boards 10 and multiple first waterproof layers 30, and multiple first circuit boards 10 are arranged at intervals along a lateral direction L1 perpendicular to the viewing direction. Multiple lamp beads 20 form multiple groups of lamp beads 20, and multiple groups of lamp beads 20 are arranged on multiple first circuit boards 10 in a one-to-one correspondence. Multiple first waterproof layers 30 are arranged on multiple first circuit boards 10 in a one-to-one correspondence.

[0052] In this embodiment, the first circuit board 10 extends in the up-down direction, and the light board assembly further includes a second circuit board 50, and a plurality of first circuit boards 10 are arranged on the second circuit board 50 and electrically connected to the second circuit board 50. The length of the second circuit board 50 in the up-down direction is less than the length of the first circuit board 10 in the up-down direction, so as to reduce the obstruction of the second circuit board 50 to the viewer's line of sight, thereby improving the transparency and permeability of the transparent LED display.

[0053] In this embodiment, there are three second circuit boards 50 arranged at intervals in the vertical direction. The three second circuit boards 50 are respectively connected to the two ends of the first circuit board 10 in the vertical direction and the middle of the first circuit board 10. The length of the second circuit board 50 connected to the middle of the first circuit board 10 in the vertical direction is greater than the length of the second circuit board 50 connected to the two ends of the first circuit board 10 in the vertical direction. The plug 51 is arranged on the side of the second circuit board 50 connected to the middle of the first circuit board 10 away from the lamp bead 20.
