According to the LED display surface treatment process is different, we can divide it into plug-in module, surface paste module, sub-surface paste module, three-in-one surface paste module, three and one surface paste module.
Plug-in module
It refers to the DIP package of the lamp will be the foot through the PCB board, through the welding will be filled with tin in the lamp hole, made by this process of LED module is plug-in module; the advantages of a large viewing angle, high brightness, heat dissipation; the disadvantage is that the pixel density is small.
Surface Mount Module
Table sticker is also called SMT, the SMT package of the lamp through the welding process on the surface of the PCB board, the lamp feet do not need to go through the PCB board, the advantages are: large viewing angle, display image soft, pixel density, suitable for indoor viewing; disadvantages are not high enough brightness, the lamp itself is not good enough heat dissipation.
Sub Surface Mount Module
Is a product between DIP and SMT, the LED light package surface and SMT, but its positive and negative level pins and DIP the same, the production is also through the PCB to weld, this kind of process is made of LED module advantages: high brightness, good display effect, the disadvantage is: process complexity, maintenance difficulties.
Three in one table sticker
Refers to the R, G, B three different colors of the LED chip encapsulated in the same gel; Advantages: production is simple, good display effect, the disadvantage is: spectral color separation is difficult, the cost is high!
Three and a table sticker
Refers to the R, G, B three independent packages of SMT lights in accordance with a certain spacing vertically side by side, so that not only has all the advantages of three in one, but also to solve the various shortcomings of three in one!
As can be seen from the above, these five different LED modules have their different advantages and disadvantages, so when customizing the LED display, according to the actual application and site conditions to choose.
