As shown in fig. 1 to 3, the small-pitch LED self-luminous display module can theoretically make a display screen infinite in a multi-module splicing manner. Referring to fig. 1, the structure of the current module is: the LED display module assembly 1 is locked on the module cavity 2, and the LED display module assembly and the module cavity are integrated and then spliced with other modules. However, the spliced screen has obvious splicing seams and splicing section differences, and the picture display effect is poor. It is mainly caused by two reasons:

(1) due to machining precision and assembly errors, peripheral sizes of the LED display module assembly 1 and the module cavity 2 are deviated;

(2) the assembling deviation of the plurality of module cavities 2 causes the flatness of the supporting surface to have a step difference and a gap.

The invention provides an LED assembly module, aiming at solving the technical problems of assembly gaps and assembly section fall existing in the existing LED assembly module.

In the embodiment of the present invention, as shown in fig. 4, the LED assembling module includes a mounting frame 10, a lamp panel supporting plate 20, and an LED display module 30. Wherein, this lamp plate layer board 20 is installed in installation frame 10 to have mounting plane 21, this LED display module assembly 30 is including installing in a plurality of LED lamp plates 31 of mounting plane 21, and a plurality of LED lamp plates 31 splice each other.

It can be understood that, according to the technical scheme of the invention, the lamp panel supporting plate 20 is installed on the installation frame 10, because the installation plane 21 of the lamp panel supporting plate 20 is a whole plane, and the plurality of LED lamp panels 31 are installed on the same plane, as long as the flatness of the installation plane 21 is ensured, the splicing segment difference of the adjacent LED lamp panels 31 can be avoided; meanwhile, the LED lamp panels 31 are spliced on the mounting plane 21, not indirectly spliced through the module cavities 2, so that precision errors and splicing errors between the module cavities 2 cannot affect the splicing of the LED lamp panels 31, and splicing gaps between the LED lamp panels 31 are avoided. Therefore, the LED display module 30 formed by splicing on the mounting plane 21 does not have splicing gaps and splicing section differences, and the display effect of the LED display module 30 is improved. It is thus clear that compare in common LED concatenation module, the LED concatenation module of this application has seamless, no segment difference, the outstanding advantage of display effect.

Further, in the present embodiment, the mounting frame 10 includes a plurality of subframes (not shown), and the subframes are spliced to each other. It is worth mentioning that the mounting frame 10 can be understood as one large module, and the sub-frame as one small module, from which a plurality of small modules can be spliced into one large module. It can be understood that a large mounting frame 10 is spliced by a plurality of sub-frames, and the mounting frames 10 with different sizes can be spliced according to different requirements, so that the applicability of the LED assembling module is improved. Moreover, the mounting frame 10 is formed by splicing a plurality of sub-frames, and the production or non-production of a specific sub-frame can be reduced, so that the manufacturing cost of the mounting frame 10 can be reduced, and the manufacturing cost of the LED assembling module can be reduced. Of course, the design of the present application is not limited thereto, and the mounting frame 10 may be separately manufactured in other embodiments of the present application.

Specifically, in this embodiment, the thickness of lamp panel supporting plate 20 is greater than or equal to 1mm, and less than or equal to 4 mm. It should be noted that, because the LED display module 30 is mounted on the lamp panel supporting plate 20, the lamp panel supporting plate 20 needs to provide enough support for the LED display module 30, and therefore the lamp panel supporting plate 20 needs to have a certain thickness. Meanwhile, when the thickness of the lamp panel supporting plate 20 is too thin, the manufacturing cost of the lamp panel supporting plate 20 is increased, and the flat installation plane 21 is not easy to prepare. Based on above-mentioned demand, combine the result of laboratory repeated test, finally obtain when lamp plate layer board 20 thinnest thickness is 1mm, can satisfy manufacturing cost simultaneously and to LED display module assembly 30's support demand. When the thickness of the lamp panel supporting plate 20 is gradually increased, the weight of the lamp panel supporting plate 20 is increased, and the fixing difficulty of the lamp panel supporting plate 20 on the mounting frame 10 is increased; moreover, the thickness of the lamp panel supporting plate 20 is increased, so that the thickness of the whole LED assembling module is increased at the same time, and the heat dissipation performance and the appearance of the LED assembling module are influenced. Based on above reason, combine the laboratory to test repeatedly and reachd, when lamp plate layer board 20's thickest thickness was 4mm, can control lamp plate layer board 20's cost of manufacture, can guarantee again that lamp plate layer board 20's fixed degree of difficulty is certain. Illustratively, in this embodiment, the thickness of the lamp panel supporting plate 20 is 2mm, and in other embodiments, the thickness of the lamp panel supporting plate 20 may also be 1mm, 1.5mm, 2.5mm, 3mm, 3.5mm, 4mm, and so on.
