LED (semiconductor light-emitting diode) packaging specifically refers to the packaging process of light-emitting chips, which is significantly different from integrated circuit packaging. LED packaging not only requires effective protection of the wick, but also ensures good light transmission performance. Therefore, there are special and strict requirements for the selection of packaging materials. The overall process of LED packaging technology begins with upstream chip manufacturing, followed by midstream packaging operations using specific packaging materials and equipment. After the packaging is completed, it needs to be driven by a power source and undergo product testing before being applied to various downstream fields, including backlighting, display screens, lighting fixtures, and cursor recognition.

The LED industry chain has a clear structure, with its upstream links mainly composed of raw material and chip manufacturers, covering the supply of raw materials such as organic silicon materials, epoxy resins, PCT, as well as the manufacturing of LED chips. The midstream stage focuses on the implementation of LED packaging technology, which is a key step in transforming chips into usable products. The downstream field covers the diversified application areas of LED packaging products, including LED display screens, landscape lighting, LED headlights, LCD backlight sources, special lighting, and traffic signals. These application areas demonstrate the broad market prospects of LED technology.

With the continuous growth of the Chinese LED industry market, the LED packaging industry has also ushered in a golden period of rapid development, showing a vigorous development trend. However, the current market concentration of China's LED packaging industry is relatively low, which means that there are many companies in the industry and competition is relatively fierce.
