The invention provides a dust-proof sealing production method of a dust collector display module and the display module, and belongs to the field of dust collector sealing structures. The production method comprises the following steps that the bottom of a display mask is coated with a layer of waterproof glue; the display mask with the bottom coated with the waterproof glue is attached to the front face of a reflection cover of the LED digital display module; a circle of sealant is applied to the periphery of the top of the display mask, then a light-transmitting lens is attached, and the display mask and the light-transmitting lens are bonded through the sealant; and a PCBA provided with a light source module is placed into the reflection cover from the back face, then a circle of sealant is applied to the edge where the PBCA and the reflection cover are combined, the PCBA and the reflection cover are completely sealed, and the waterproof glue and the sealant are both normal-temperature curing sealant. The dust-proof sealing production method has the advantages of being free of baking, free of deformation, free of influences on light emitting, high in reliability and the like.
Description
technical field [0001] The invention relates to a vacuum cleaner sealing process, in particular to a dust-proof sealing production method for a vacuum cleaner display module, and also relates to a display module produced by the production method. Background technique [0002] Under normal circumstances, in the LED digital display and electronic packaging industries, in order to achieve the dustproof effect of the product, epoxy resin or electronic silica gel is usually used for landfill sealing, that is, all electronic components are sealed in glue to realize the dustproof sealing function. Because epoxy resin needs to be baked at high temperature, and there is a large stress release during the reaction process, it is easy to cause deformation of the entire LED display module; and if the glue such as silica gel covers or completely buries the LED light-emitting element, it will cause color difference. And the cost is higher. Contents of the invention [0003] In order to ...
