LED TV can be half cheaper after 3 to 5 years

In daily life, LEDs have appeared more and more, but the price is still relatively expensive and prohibitive. However, the reporter learned from the Advanced Photonics Center of Southeast University that the center is studying a new LED production technology and is expected to reduce LED-related products by about half in 3-5 years.

"LED things are very good, very energy-efficient, but the price is too expensive, we ordinary people are still very hard to buy." Mr. Xu fancy a LED TV, but the price of tens of thousands of dollars made him "distracted." “The LED we are developing is using silicon wafers as the substrate.” Professor Zhang Xiong said that compared with the current sapphire in the LED industry, silicon wafers can be as large as 8 or even 12 inches, while sapphire wafers are generally only up to 4 inches. The larger the substrate size, the less the chip processing loss and the lower the production cost; now the same size silicon wafer is only less than one-third of the sapphire price. "At present, our research and development work has just begun. It is expected to be industrialized in a large scale in the next 3-5 years. If the research and development is successful, the price of LED products will drop significantly. For the most common LED TV, the price will drop by half. about."
