As we all know, led display has 5 different LED modules, and different modules also have different advantages and disadvantages, so in the custom LED screen, the customer needs to understand the characteristics of LED screen module, can be based on the actual Application and site conditions to choose. Here we come together to understand some of the led display module.
According to the LED screen surface treatment process is different, we can be divided into plug-in module, table paste module, sub-table paste module, triple die module, three and a table paste module.
First, plug-in module
Refers to the DIP package of the lamp through the PCB board, through the welding of tin filled in the lamp hole, made by this process is the LED module plug light module; the advantages of large viewing angle, high brightness, heat Good; the disadvantage is that the pixel density is small.
Second, the table paste module
Surface mount is also called SMT, the SMT package of light through the welding process welding on the surface of the PCB board, the lamp does not have to go through the PCB board, the advantages are: large viewing angle, showing the image is soft, pixel density, suitable for indoor viewing; The brightness is not high enough, the lamp itself is not good enough heat dissipation.
Three, sub-table paste module
Is between DIP and SMT between a product, the LED lamp package surface and SMT the same, but its positive and negative pin and DIP, the same is produced through the PCB to the welding, such a process to do Into the LED module advantages are: high brightness, good display, the shortcomings are: complex process, maintenance difficulties.
Four, three in one paste
Refers to the R, G, B three different colors of the LED chip package in the same colloid; advantages: simple production, display good, the drawback is: poor color separation, high cost.
Five, three and a paste
Refers to the R, G, B three separate packaging of the SMT lights in accordance with a certain distance vertically tied together, so that not only has all the advantages of triple play, but also solve the various disadvantages of triple play.
