Embodiment 1
[0066] In one embodiment, such as image 3 with Figure 5 As shown, the present invention provides a LED display module packaging method. In this embodiment, two LED display modules are taken as an example for illustration.
[0067] A LED display module packaging method, the method comprising:
[0068] S401. Divide two LED display modules to be packaged into a row with an interval of 0.1 mm, and place them on the glue potting jig upside down with the display surface facing down.
[0069] S402. Paste a sealing tape on the back of the adjacent LED display modules, and the sealing tape covers the gap between the adjacent LED display modules.
[0070] S403. Open an air extraction hole at the center of the sealing tape.
[0071] S404, arrange a layer of hot melt glue with a certain thickness and height on the periphery of the side-by-side LED display modules to prevent the packaging glue from overflowing into the back of the LED display modules and making it difficult to remove...

Abstract
The invention discloses an LED display module packaging method. The method comprises the following steps of dividing a plurality of to-be-packaged LED display modules into a plurality of rows at predetermined intervals, and inversely placing the rows on a glue pouring jig in a manner that display surfaces face downwards; pasting a sealing tape on a back surface of the adjacent LED display module,wherein the sealing tape covers the preset interval of the adjacent LED display module; forming an air exhaust hole in the sealing belt; injecting packaging glue into the periphery of the LED displaymodule so that all the LED display modules to be packaged are filled with the packaging glue; vacuumizing the air exhaust hole till the glue filling is completed; and placing the LED display module subjected to glue pouring at the normal temperature or the high temperature so that the packaging glue is cured. The method is advantaged in that vacuumizing operation is carried out above the module, so convenience of the vacuumizing operation is greatly improved, and packaging efficiency of the LED display module is improved.
Description
technical field [0001] The invention relates to the field of display screens, in particular to an LED display module packaging method. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) display is a self-luminous display technology, which can realize infinite splicing and high-definition display. With the development of technology, the display accuracy of LED displays is getting higher and higher. Products with a pixel pitch below 2.0mm have been used on a large scale, and the market is rapidly penetrating into the direction of pixel pitch below 1.0mm. This trend not only brings people a more shocking visual experience, but also brings new challenges to users. That is, as the pixel pitch shrinks, the pixels (LED lamp beads) must also be reduced accordingly, so that these smaller and smaller ones become more and more fragile and vulnerable during the installation and maintenance of the LED display. [0003] To solve this problem, people have deve...
