Description

Technical Field

[0001] The present application relates to the field of LED display technology, and in particular to an outdoor transparent LED display module. Background Art

[0002] The outdoor transparent LED display screen is mainly composed of a module frame and a plurality of outdoor transparent LED display modules. In order to ensure the sealing performance inside the outdoor transparent LED display module and to form a better sealing protection for all the electrical components installed therein, some outdoor transparent LED display modules adopt an overall glue-filling structure, that is, after the module light board and the module bottom shell are assembled together, they are overall glue-filled and packaged to form an integrated glue-filling module device. In this way, since the module light board of the existing outdoor transparent LED display module generally adopts a structural design of front lamp beads and back driver chips, this will cause the glue-filling module device to be unrepairable. This is because if the back driver chip of the glue-filling module device is to be repaired, the overall package of the glue-filling module device needs to be destroyed, resulting in the scrapping of the entire glue-filling module device. Utility Model Content

[0003] The embodiment of the present application provides an outdoor transparent LED display module, which aims to solve the technical problem that the module light board of the existing outdoor transparent LED display module adopts a structural design of front lamp beads and back drive chips, resulting in that the glue-filled module components cannot be repaired.

[0004] To this end, the first embodiment of the present application provides an outdoor transparent LED display module, comprising a module light board and a module bottom shell; the module light board is laid on a side surface of the module bottom shell, and a glue-filling structure is used to encapsulate the module light board and the module bottom shell into an integrated glue-filling module device;

[0005] The module lamp board includes a hollow PCB body, a plurality of LED lamp beads and a plurality of driver ICs. The plurality of LED lamp beads are distributed in a matrix on the first surface of the hollow PCB body, and in the non-hollow area of ​​the first surface, there is no position for the plurality of LED lamp beads, and a plurality of driver ICs are also provided, so that the plurality of driver ICs and the plurality of LED lamp beads are all located on the first surface, which is a side surface of the hollow PCB body away from the module bottom shell.

[0006] Optionally, in some embodiments of the present application, the hollow PCB board body includes at least one first board body segment and at least one second board body segment, the second board body segment is located in the longitudinal extension direction of the first board body segment, and the length of the second board body segment in the longitudinal extension direction is less than the length of the first board body segment in the longitudinal extension direction, the first board body segment adopts a hollow structure, and the second board body segment adopts a non-hollow structure, and a number of the driver ICs are arranged in the gap between four vertically and horizontally adjacent LED lamp beads on the second board body segment.

[0007] Optionally, in some embodiments of the present application, the first plate section is provided with a plurality of first openings arranged at equal intervals along its width direction, and each of the openings is extended along the longitudinal extension direction, and the LED lamp beads arranged on the first plate section are distributed on two opposite sides of each of the first openings in the transverse direction.

[0008] Optionally, in some embodiments of the present application, the portion of the module bottom shell corresponding to each of the first plate segments is provided with second openings arranged one-to-one with the plurality of first openings, so that when the module light board is laid on one side surface of the module bottom shell, the module bottom shell will not form any obstruction to all the first openings.

[0009] Optionally, in some embodiments of the present application, the hollow PCB body includes two first board segments and three second board segments connected to each other in the longitudinal extension direction, and one first board segment is arranged between every two second board segments.

[0010] Optionally, in some embodiments of the present application, the module light board also includes a light board connector, which is arranged on the second surface of the hollow PCB board body and is located on a second board body segment; a portion of the module bottom shell corresponding to the second board body segment is provided with an avoidance hole for avoiding the light board connector; the second surface is a side surface of the hollow PCB board body close to the module bottom shell.

[0011] Optionally, in some embodiments of the present application, a waterproof sealing ring is provided at the contact position between the peripheral side of the avoidance hole and the hollow PCB board body.

[0012] Optionally, in some embodiments of the present application, a plurality of magnets are installed on a surface of a side of the module bottom shell away from the module light board; and a plurality of magnets are also installed at intervals on the second surface.

[0013] The outdoor transparent LED display module provided by the technical solution of the present application has several driver ICs arranged in the non-hollow area of ​​the first surface, instead of the positions where several LED lamp beads are arranged. Such positions make several driver ICs and several LED lamp beads all located on the first surface, and the first surface is the side surface of the hollow PCB board away from the bottom shell of the module. That is, all LED lamp beads and all driver ICs of the outdoor transparent LED display module are arranged on the front of the module light board.

It can be seen that the technical solution can solve the technical problem that the module light board of the existing outdoor transparent LED display module adopts the structural design of the front lamp beads and the back driver chip, which makes the glue-filled module device unrepairable.

[0021] In one embodiment, Figure 1 and Figure 2 As shown, the embodiment of the present application provides an outdoor transparent LED display module 100, which includes a module light board 110 and a module bottom shell 120. The module light board 110 is laid on a side surface of the module bottom shell 120, and a glue-filling structure is used to encapsulate the module light board 110 and the module bottom shell 120 into an integrated glue-filling module device. The module light board 110 includes a hollow PCB board body 111, a plurality of LED lamp beads 112, and a plurality of driver ICs 113. The plurality of LED lamp beads 112 are distributed in a matrix on the first surface of the hollow PCB board body 111, and in the non-hollow area of ​​the first surface, there are no positions where the plurality of LED lamp beads 112 are provided, and a plurality of driver ICs 113 are also provided, so that the plurality of driver ICs 113 and the plurality of LED lamp beads 112 are all located on the first surface, and the first surface is a side surface of the hollow PCB board body 111 away from the module bottom shell 120.

[0022] It can be understood that the outdoor transparent LED display module 100 of the embodiment of the present application is mainly used to splice to form a corresponding outdoor transparent display screen, which is mainly set outdoors and can display content through itself while allowing the scenery behind it to pass through, so that the audience can see the scenery behind the screen to increase the visual effect and sense of space. The first surface mentioned above is specifically the front of the module light board 110, and the second surface mentioned below is specifically the back of the module light board 110. In the non-hollow area of ​​the first surface mentioned above, there is no position where a number of LED lamp beads 112 are set, and a number of driver ICs 113 are also set, which specifically refers to that a number of driver ICs 113 are distributed in the non-hollow area of ​​the first surface together with a number of LED lamp beads 112 without affecting the matrix distribution of the number of LED lamp beads 112.

[0023] In addition, the horizontal direction mentioned in the embodiment of the present application mainly refers to the width direction of the hollow PCB body 211 , and the vertical direction mainly refers to the length direction of the hollow PCB body 211 .

[0024] In this way, the outdoor transparent LED display module 100 of the embodiment of the present application is provided with a plurality of driver ICs 113 in the non-hollow area of ​​the first surface, where the plurality of LED lamp beads 112 are not provided, so that the plurality of driver ICs 113 and the plurality of LED lamp beads 112 are all located on the first surface, and the first surface is a side surface of the hollow PCB board 111 away from the module bottom shell 120. That is, all the LED lamp beads 112 and all the driver ICs 113 of the outdoor transparent LED display module 100 are arranged on the front of the module light board 110. In this way, even if the module light board 110 and the module bottom shell 120 are packaged into an integrated glue-filled module device through the glue-filling structure, when the glue-filled module device fails, the glue-filling structure can be partially destroyed for targeted repair of the damaged driver IC part, and then the glue-filling repair can be performed.

[0025] In some examples, such as Figure 1 and Figure 2 As shown, the hollow PCB body 111 includes at least one first body section 1111 and at least one second body section 1112, the second body section 1112 is located in the longitudinal extension direction of the first body section 1111, and the length of the second body section 1112 in the longitudinal extension direction is less than the length of the first body section 1111 in the longitudinal extension direction, the first body section 1111 adopts a hollow structure, the second body section 1112 adopts a non-hollow structure, and a plurality of driver ICs 113 are arranged in the gap between four vertically and horizontally adjacent LED lamp beads 112 on the second body section 1112. In this way, the above-mentioned structure can be arranged so that sufficient arrangement space is reserved for a plurality of driver ICs 113 through the second body section 1112, and the hollowing rate of the entire hollow PCB body 111 can be ensured through the arrangement of the first body section 1111, so as to ensure the transparent display effect of the outdoor transparent LED display module 100. In addition, by arranging a plurality of driving ICs 113 in a relatively concentrated manner on the second board section 1112, when a failure occurs in the glue-filling module component, it is convenient to concentrate on repairing the corresponding part of the second board section 1112 without damaging other parts.

[0026] It is understandable that the hollow structure mentioned in this example specifically refers to the hollowing rate of the first board segment 1111 being greater than or equal to 50%, and the non-hollow structure mentioned in this example specifically refers to the second board segment 1112 having no openings as a whole, or a hollowing rate of less than 10%. Therefore, in addition to leaving enough space for the driver ICs 113 and the corresponding LED lamp beads 112, the second board segment 1112 can have several small openings (not shown in the figure) at appropriate positions to increase the hollowing rate of the entire hollow PCB board 111.

[0027] In some examples, such as Figure 1 and Figure 2 As shown, the first plate section 1111 is provided with a plurality of first openings (not shown) arranged at equal intervals along its width direction, and each opening is extended along the longitudinal extension direction, and the LED lamp beads 112 arranged on the first plate section 1111 are distributed on two opposite sides of each first opening in the transverse direction. In this way, the hollowing rate of the first plate section 1111 can be increased as much as possible by setting a plurality of first openings, so as to ensure the hollowing rate of the entire hollow PCB board 111, and further ensure the transparent display effect of the outdoor transparent LED display module 100.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, the module bottom shell 120 corresponds to a portion of each first plate segment 1111, and is provided with second openings (not shown in the figure) arranged one-to-one with the multiple first openings, so that when the module light board 110 is laid on one side surface of the module bottom shell 120, the module bottom shell 120 will not form any obstruction to all the first openings, that is, each second opening is consistent in size with the corresponding first opening, so as to ensure the transparent display effect of the outdoor transparent LED display module 100.

[0029] In some examples, such as Figure 1 and Figure 2 As shown, the hollow PCB body 111 includes two first body segments 1111 and three second body segments 1112 connected in the longitudinal extension direction, and a first body segment 1111 is arranged between every two second body segments 1112. In this way, through the above-mentioned structural arrangement, the main part of the hollow PCB body 111 is mainly composed of the first body segment 1111 of the hollow structure, thereby ensuring the hollowing rate of the entire hollow PCB body 111, thereby ensuring the transparent display effect of the outdoor transparent LED display module 100.

[0030] In some examples, such as Figure 1 and Figure 2As shown, the module light board 110 also includes a light board connector 114, which is arranged on the second surface of the hollow PCB board body 111 and is located on a second board body section 1112. A avoidance hole 121 for avoiding the light board connector 114 is opened in the portion of the module bottom shell 120 corresponding to the second board body section. The second surface is a side surface of the hollow PCB board body 111 close to the module bottom shell 120. In this way, when the outdoor transparent LED display module 100 is connected on the module frame to form an outdoor transparent LED display screen, the electrical connection between it and the control component on the module frame can be more conveniently achieved through the setting of the light board connector 114. Further, a waterproof sealing ring 130 is provided at the contact position between the peripheral side of the avoidance hole 121 and the hollow PCB board body 111 to ensure the waterproof performance of its internal components. Furthermore, a plurality of magnets 140 are installed on the second surface. In this way, when the outdoor transparent LED display module 100 is connected on the module frame to form an outdoor transparent LED display screen, the plurality of magnets 140 can be arranged so that the outdoor transparent LED display module 100 can be quickly adsorbed and fixed on the corresponding position of the module frame by magnetic adsorption.

[0031] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the utility model concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
