The World's First 3G LED Display Was Born in China

Access:361 Time:2018.06.10
After more than 10 years of scientific and technological breakthroughs, China has made major breakthroughs in the field of world LED display. In this field, the concept of “integrated three in one ”was first introduced, and the world's first  "integrated three in one" LED display was developed. At present, this result has applied for 12 patents, including 9 national invention patents, marking China's LED display has ranked among the world advanced class. At present, the world LED display market is dominated by products such as "tab of three in one", but its unavoidable defect is that the LED display using the surface-mounting process needs to undergo single-tube encapsulation and secondary welding in the production process, and the temperature requirements for the secondary welding is more stringent. If the temperature is too high, it is easy to damage the die, and if the temperature is too low, it is easy to cause rosin joint.

The secondary welding has high requirements on the precision of the equipment in the manufacturing process. The welding temperature, the alignment accuracy of the chip mounter, the welding material used, and the thickness of the halftone all have a great influence on its reliability. According to reports, the emergence of "integrated three in one" will change the setup of the current world LED display market which was dominated by "tab of three in one". Compared with it, the raw material costs and production equipment investment costs of the "integrated three in one" LED display is very low, and it is the best in the display effect, process availability, product reliability and so on, with the highest cost performance ratio, which will become the mainstream products in the future.
