In the LED full-color display production process, packaging is a very important solution. Nowadays, there are two common outdoor LED display packaging methods on the market: DIP and SMD packaging. What is the difference between these two packages, and what are the advantages and disadvantages? Shenzhen LED display manufacturer Lianchengfa LCF will answer for you next:

What is the role of LED display package?

Connect the outer leads to the electrodes of the LED display chip, and at the same time protect the LED display chip, improve the luminous efficiency and heat dissipation environment, and then increase the life of the LED.

1. DIP package

DIP package, is the abbreviation of dual inline-pin package, commonly known as plug-in type. It was the first to develop. The LED lamp beads are produced by the manufacturer, and then the LED module and LED display manufacturer insert it into the LED PCB light board, and after wave soldering, the semi-outdoor module and outdoor waterproof module of DIP are produced.

However, due to the influence of the diameter of the lamp beads, it can only be P6 at present. Other P5, P4 and even higher density outdoor LED displays cannot be made. But the in-line protection performance is good, but the viewing angle is not easy to fix accurately, generally between 100-110, and high energy consumption, not environmentally friendly, so it is only suitable for outdoor small-pitch LED displays. At present, P10-P20 are still outdoor. Have a larger market share.

It also adopts DIP packaging method to produce, the process is complicated, it is not easy to mechanize production, and the production efficiency is low. In addition, there are many DIP manufacturers without high technology and equipment thresholds. The competition is fierce. Many manufacturers use inferior raw materials and PCB boards to reduce costs to gain market share. The quality is low and there is almost no perfect after-sales guarantee.

2. SMD package method

SMD package means: surface mount device, which is one of SMT components. Surface mount components were introduced about twenty years ago, and this has ushered in a new era. For a long time, people believed that all pin components could eventually be packaged in SMD. SMD technology is widely used in LED outdoor displays.

The three-in-one forehead label, which we often say, is actually a type of SMD technology, which refers to the SMT lamp packaged with three different colors of RGB LED chips in the same gel at a certain interval.

The advantages of the label three-in-one outdoor full-color LED display are as follows: the viewing angle of the whole screen is larger than that of the in-line screen, and the surface can be treated with diffuse reflection, the result is not granular, the color saturation is high, and the color uniformity is good. . Three-in-one overall flatness is easier to control, and it has always been the standard technology used in high-definition outdoor LED displays.

With the development of technology and the continuous improvement of production technology in recent years, SMD has developed rapidly, and the cost has been reduced a lot. It is currently the mainstream product of LED indoor display. And it has developed rapidly to the outdoor market, but brightness and waterproof and moisture-proof have always been difficult to overcome. Believe that the entire industry continues to develop, the development of outdoor LED display is the direction of surface mount.
