1. Look at the welding point

The advanced SMT patch process used by the high -quality LED light produced by the professional and regular Anhui LED display, while the inferior lamp bands are produced with back welding and tin paste process.

2. Look at the surface of the LED light belt smooth

The difference is whether to use the SEM process to produce light bands, and mainly depending on whether the surface of the LED light belt is very clean, and no obvious stains and impurities can be seen. For inferior LED lights, you will find that you will find that the surface is particularly dirty, and there is a particularly big odor that makes people very uncomfortable.

3. Use the detection equipment to detect LED lamp beads

It is difficult to see if you use your eyes to see if the LED lamp beads are high -quality, so it is recommended that you use the detection equipment to test it. You can put several manufacturers LED on the aging instrument and use the maximum current for 24 hours. During the decline, it means that that is better LED lamp bead.

After reading it, tell you this way to distinguish the LED lamp beads, I believe I will know how to choose a good quality LED lamp bead in the future. Low quality is definitely a problem. If you want to use the LED display for a long time, it is recommended not to buy low -priced products, so as not to affect your own interests.
