LED display surface treatment type
1. Plug light 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 module is the plug light module; the advantages of large viewing angle, high brightness, good heat dissipation ; The disadvantage is that the pixel density is small.
2. Surface mount module
Surface mount is also called SMT, the SMT package of the lamp through the welding process welding in the PCB board surface, the lamp does not have to pass through the PCB board, made by this process module is called the table paste module; advantages are: Display the image is soft, pixel density, suitable for indoor viewing; drawback is not high enough brightness, the lamp itself is not good enough heat
3. 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 pins and DIP, the same is produced through the PCB to the welding, the advantages are: High brightness, good display, the shortcomings are: complex process, maintenance difficulties.
4. Triple play
Refers to the R, G, B three different colors of the LED chip package in the same colloid; Advantages: simple production, display good, the disadvantage is: poor color separation, high cost.
5. Three and a paste
Refers to the R, G, B three separate packaging of the SMT lights in accordance with a certain distance perpendicular to the side together, so not only has all the advantages of triple play, but also solve the various drawbacks of triple play.
