specific Embodiment approach

[0093] Further, see figure 2 , as a specific embodiment of the LED display module manufacturing method provided by the present invention, further comprising the following steps:

[0094] S4: Demoulding, performing finishing treatment on the cured and formed protective layer.

[0095] After demoulding, after the glue is cured and formed into the protective layer 20 , the protective layer 20 needs to be finished, and the finishing includes polishing and cutting the protective layer 20 .

[0096] Furthermore, as a specific implementation of the LED display module manufacturing method provided by the present invention, during the mold closing process of the upper mold 40 and the lower mold 30, the upper mold 40 is gradually mold-closed at an initial inclination angle until the upper mold 40 and the lower mold 30 are closed. The mold 30 fits perfectly, which prevents the upper mold 40 from pressing residual air into the glue solution during the mold closing process, and also prev...

Abstract

The invention provides an LED display module manufacturing method. The LED display module manufacturing method comprises the steps of 1, providing an LED display module, glue liquor, a mold, a mold closing device and a vacuum extraction box body, wherein the mold comprises an upper mold and a lower mold, and by means of the mold closing device, the upper mold can be moved to be closed with the lower mold; 2, maintaining the interior of the vacuum extraction box body in the vacuum state, injecting the glue liquor into the lower mold in the vacuum extraction box body, and then, moving the uppermold to be closed with the lower mold through the mold closing device; and 3, conducting solidification. By means of the LED display module manufacturing method, glue filling and mold closing are conducted in a vacuum environment, and the problems that air is mixed into glue liquor, and bubbles are generated after the glue liquor is solidified are avoided; and the light permeation effect achievedafter the glue liquor is solidified and molded into a protective layer is improved.

Description

technical field [0001] The invention belongs to the technical field of LED display screens, and more specifically relates to a method for manufacturing an LED display module. Background technique [0002] LED display modules usually include a substrate for realizing control functions and several LED lamp beads arranged on one side of the substrate. In order to ensure the display effect, the LED lamp beads usually have less protective structures or are even exposed. The bumps caused by the unavoidable handling of the LED display module during use, as well as different climatic environments (water vapor, acidity and alkalinity, high and low temperature, ultraviolet rays) will bring differences to the substrate of the LED display module and the exposed LED lamp beads. degree of damage. At present, the service life of LED display modules in relatively harsh environments is usually only one year or even half a year, resulting in high cost of use and lack of market competitivenes...
