In the LED display manufacturing processes, packaging is a very important part, and now, there are three outdoor led display package on the market: DIP, SMD. What are the pros and cons of these two encapsulation mode, which is the difference between a look.

We know the role of packaging is the outer leads are connected to the LED chip electrode, while protecting the LED chip, and has played the role of improving the luminous efficiency, good packaging allows LED luminous efficiency and have better thermal environment, and thus enhance LED life.

A, DIP package

DIP package, dual inline-pin package abbreviation, commonly known as plug-lamp display. There are three package model was first developed. Lamp beads are manufactured by LED lamp beads packaging manufacturers, and then by the LED module and display manufacturers to insert it into the LED lights PCB board after wave soldering DIP to produce semi-outdoor and outdoor waterproof module module. Initially, the red, green and blue lights inserted in the PCB compose an RGB pixels, the latter has three chip RGB can be encapsulated within a lamp beads, namely outdoor triple full color, relatively speaking, to improve production efficiency and production costs.

Two, SMD package

Triple is an LED display SMD technology refers to the RGB three different colors of LED chip package of SMT lamp package in accordance with a certain distance in the same colloid technology uses triple SMD full-color LED display Angle DIP screen the whole screen is relatively large, and the surface of the diffuse light can do processing, the resulting effect is not granular, uniform color is good. Speaking from the colors, triple full-color separation by relatively easy three-mile, and color saturation. Triple is with the entire surface to light, so the overall color more even triple. Triple the overall flatness of the easier to control. It has been a standard technique used in high-definition LED display.

In recent years due to the continuous improvement of the rapid development of triple play technology and production processes, and extensive use of automated equipment, SMD rapid development, it costs a lot, is currently the mainstream products LED indoor display. And it has begun to outdoor display market penetration, but the brightness and outdoor waterproof, moisture, dust, anti-static, anti-oxidation has been its insurmountable divide.
