At present, the civil LED lamp market is in the bottleneck period before the outbreak, and the major LED lamp chip factories are living on thin ice. Some LED lamp enterprises did not survive last winter, and died before spring, even if they did not die, they lost a lap. The key is that a group of people will die before the arrival of spring, and the choice of chip substrate route determines life and death.
Bian Difei, vice president of Huacan Optoelectronics, believes that this (referring to the route selection of LED lamp chip substrate) is still a mystery. Just like the mobile phone operating system, Saipan was in full swing in the past, and its admirers were like fish crossing the river. Today, it is almost dead, but it is just surviving. Apple's ios was a symbol of status and status last year, and now it shows signs of decline. Android seems to be the star of tomorrow. No Android phone is like an overseas Chinese coming back from Mars, which is too OUT.
Sapphire substrate is superior to users. Similar to Android system, technology is constantly developing, especially PSS (Sapphire Patterned Etching) technology, which can greatly improve photoelectric conversion efficiency. Gallium nitride has always been a representative of high quality, but its cost has always been a mystery, and because of the strict patent protection of Corey, similar to Apple's ios, it is difficult for other manufacturers to enter. The silicon substrate is like a fairy flying from the sky, fighting from a seemingly impossible place, but its light output rate and yield have always been unsatisfactory, at least for the time being, it has no commercial competitiveness, but many new overlords have passed this barrier, which seems to imply something.
The routing choice of LED lamp chip substrate is not a problem for terminal lamp manufacturers at all. I will use whoever is good, but this is a major event for chip manufacturers, and life and death have to be judged. Gong Liu of Chengdu Chaoyue Optoelectronics said that under the pressure of life and death, all chip manufacturers have invested heavily in research and development of improved technologies, and achieved the final victory, which has contributed to reducing the cost of chips and accelerating the popularization of LED lamps. LED lamp enterprises are inevitably secretly gloating.
However, after the chip war has come to an end, it is the turn of LED lamp manufacturers to compete in the sea. This will also be a battle of life and death. Eighty thousand manufacturers joined the battlefield, and less than eight thousand survived.
