LED cost analysis, materials and components industry trends
LED (Light Emitting Diode) is a kind of light-emitting component that applies voltage to two terminals of the positive and negative electrodes in the semiconductor. When the current passes, the electrons are combined with the hole, and the excess energy will be released in the form of light to reach the light. Effect. White LEDs have been applied to panel backlight modules, car lights, and general-purpose lighting. In the future, the application market will become increasingly popular and gradually extended to other applications. LED has the advantages of long life, environmental protection, low energy consumption, etc. It can be expected to be widely used in many light source markets. If LED replaces the traditional light source as a substitute lamp, it will have a considerable impact on the light source market. In the field of LED applications, LCD backlight illumination, automotive lighting and urban landscape lighting applications have become the main growth of the LED market. In the future, new LED application products will become part of the living space, driving the new state of life technology application market, continuing to The trend of taking root. And as new applications continue to expand, LED product application design will shift from the original subsidiary design concept to a dominant position.
Therefore, this study explores the various structures and processes and cost structures of LEDs, and will analyze key material and component trends and price trends. In addition to the final appendix, the main content is divided into three chapters:
The first chapter provides an in-depth introduction to the LED process, substrate monocrystalline silicon process, epi-wafer process and die process.
The contents of the second chapter are mainly the detailed analysis of the key materials and product structure of the LED, the cost of the die and the package of each size.
The third chapter analyzes the key materials and components of LED and the industry trends, such as monocrystalline silicon substrate, wafer and die, substrate (PCB substrate, lead frame, ceramic substrate, WLP), molding package material (epoxy Price trends for resins, silicones, phosphors, key materials and components. As for the annex, the LED industry chain will be detailed.
The results of this research will be beneficial to the upstream and downstream related industries of LEDs such as monocrystalline silicon substrates, epitaxial wafers and crystal grains, substrates, molding and packaging materials, and phosphor powder, as well as those who plan new investment in the LED industry to grasp the real-time and accurate status. It can be used as a reference for the feasibility analysis of new investment plans. (Displaybank)
