At present, the LED(light emitting diode) as main components for LED display, there are mainly two kinds of packages, namely the Direct Insert Package(DIP) and Surface Mounted Devices(SMD). Generally speaking, DIP LED mainly used in outdoor LED display screen, and the SMD LED is applied to indoor LED screen. In addition, what is the other difference they have?

DIP LED using potting form for packaging. Potting process is injected liquid epoxy resin in LED the molding cavity at first, and then insert the pressure LED bracket welding good put them into the oven for epoxy resin after curing in order to make the LED molded from the mold cavity.  Due to the simple fabrication process, low cost, it have a higher market share. In large volume, can be used to artificial insert or AI machine operation, because the DIP LED high brightness, easy to waterproof processing, so the general light source for outdoor LED display screen.

However, the SMD LED is attached on the surface of PCB, suitable for SMT processing, can be reflow, solves the brightness, angle of view, flatness, consistency, reliability and other issues, the lighter PCB plate and a reflecting layer material, improvement of removing heavier carbon steel pin of DIP LED , the display epoxy resin less reflective layer to fill, to reduce the size, reduce weight. Thus, surface mount LED can easily integrate product weight by half; eventually make the application more perfect.

SMT LED source for indoor LED screen, but with technological breakthroughs, brightness SMD LED has been greatly improved, waterproof processing can also be well resolved, therefore, SMD LED is more and more applied to the outdoor LED display.
