Three key factors to reduce the cost of LED display

As an efficient display technology, LED display screen has been widely used in various industries. However, its relatively high cost has been a major factor limiting wider application. In order to promote the breakthrough of LED displays in the more challenging new field of general lighting, cost reduction has become particularly critical. Here are three key factors that can significantly reduce the cost of LED displays:

Increase in wafer size

At present, the manufacturing cost of LED display devices is higher than that of silicon-based devices. This is mainly because the scale and technological maturity of the LED industry have not yet reached the level of the silicon-based semiconductor industry. By increasing the size of the processed wafer, for example from the mainstream 2-inch wafer to 4-inch, the processing cost of the chip process can be greatly reduced. The increase in wafer size means that more chips can be cut from the same wafer, thus reducing the cost of a single chip. How does an LED chip emit light?

Improvement of production efficiency

The advancement of LED electronic display core equipment manufacturing technology, especially MOCVD (metal-organic chemical vapor deposition) equipment, is the key to improving production efficiency. MOCVD is the main equipment for the epitaxial growth of GaN (gallium nitride), which is a key material in LED displays. Through technological advancement, the productivity of MOCVD equipment has been improved and high-quality epitaxial wafers can be produced more efficiently, which will significantly reduce the depreciation cost of LED displays.

Expansion of industrial scale

As the scale of the LED display industry expands, raw material costs and comprehensive management costs will be effectively reduced. Economies of scale mean that as production volume increases, the cost per unit of product decreases. In addition, large-scale production can also promote the optimization of the supply chain, reduce logistics and procurement costs, and further improve industrial competitiveness.

future outlook

Based on the above factors, it is expected that the cost of LED display chips will continue to decline in the next 10 years. This cost reduction will further stimulate the development of LED in emerging application fields, such as smart lighting, agricultural lighting, medical lighting, etc. Through the unremitting efforts of LED display manufacturers, technological improvements and cost reductions will make LED displays more popular and bring more economic benefits to society.

Conclusion

Reducing the cost of LED display screens is not only a technical issue, but also an issue of industrial scale and market strategy. With the advancement of technology and the expansion of industrial scale, LED displays are expected to become more economical and environmentally friendly display solutions in the future, bringing more convenience to people's daily life and work.
