Detailed Description
The present invention will be further described with reference to the following description and embodiments.
As shown in fig. 3 to 4, an LED display module with a stable structure and good flatness comprises a bottom case 1, a plurality of printed circuit boards 2 and an LED3, wherein the LED3 is disposed on the printed circuit boards 2, the plurality of printed circuit boards 2 are assembled and fixed on the bottom case 1, a glue filling layer 6 is filled between each printed circuit board 2 and the bottom case 1, and the flat assembly of the plurality of printed circuit boards 2 can be realized by utilizing the advantage of the adjustable thickness of the glue filling layer 6, so as to meet the requirement of a flat display surface.
And the bottom shell 1 is provided with a glue injection hole 7.
The glue outlet of the glue injection hole 7 is arranged between the printed circuit board 2 and the bottom shell 1, and glue can be injected into the gap between the printed circuit board 2 and the bottom shell 1 through the glue injection hole 7 to form a glue filling layer 6.
Each printed circuit board 2 is at least corresponding to one glue injection hole 7.
The glue injection hole 7 is in a horn-hole shape.
The glue filling layer 6 is formed by filling fast-curing glue.
The glue filling layer 6 is formed by filling high-performance hot melt glue.
The printed circuit board 2 is connected with a patch copper column 4, the bottom shell is provided with a mounting fastening screw 5, and the mounting fastening screw is connected with the patch copper column 4 by the mounting fastening screw 5.
The LED3 and the printed circuit board 2 form an LED display panel, the LED display panel can adopt two different structures, one is a surface mount structure, the LED3 is preferably an LED lamp bead, namely the LED lamp bead is pasted on a PCB (namely PCB + LED packaging device), commonly called as an SMD (surface mount device) display lamp panel, the other is chip-on-board packaging, namely COB, the LED display lamp panel is integrally packaged, the LED3 is preferably an LED chip, namely the LED chip is directly bonded on the PCB, and a layer of protective glue is sealed on the surface.
