In the field of LED packaging, the performance of basic materials such as blue chips, phosphors, and encapsulation adhesives has been brought to the extreme, and it is difficult to make breakthroughs. Mini/Micro LED is comparable to OLED performance, with lower cost, high degree of fit in the domestic industry chain, and rapid development. However, its packaging has many technical difficulties. In order to improve the light efficiency, the Zener tube and the gold wire solder joints are covered with high reflectivity white glue.
