2011- The price trend of 2-inch sapphire substrate in 2014 shows that sapphire prices have fallen sharply since 2011, and it is almost difficult for Sapphire prices to return to their previous prices in the next two years. In the 2014 quarter, the price of sapphire rose slightly, driven by the re-application end, but by a small margin. Although Sapphire has warmed up from concept to market since the quarter of 2014, the price has also begun to change, and the sound of price increases is endless, but according to our observation, the current price increase of 2-inch sapphire is not large, basically, it is about 8 US dollars, but 4-inch sapphire, which has risen from 28 US dollars to 35 US dollars since the third quarter of 2013. Of course, this is in line with the high market demand for 4-inch sapphire, another reason is that the price of crystal rods continues to rise. The 4-inch crystal rods rose from 12 US dollars/mm at the end of 2013 to 15 US dollars/mm, resulting in an increase in the cost of substrate manufacturers, this is also one of the reasons for the price increase of 4-inch sapphire. The price trend analysis of 2-inch sapphire substrate in LED industry shows that with the development of technology and the continuous delivery of production capacity, the increase in quantity and the decrease in price are inevitable; The substrate goes from 2 inch to a higher size (4 inch ~ 8 inch)The upgrade is also the general trend; While the consumer electronic products led by Apple begin to adopt sapphire materials step by step, which will bring a new round of upgrading tide; New capacity, new applications, new prices, Sapphire will be owned by everyone in the near future, becoming one of the commonly used materials for consumer electronics, and flying into the homes of ordinary people will become a reality. Then, to sum up, the sapphire market will flourish under the drive of LED and related consumer electronics, but the price growth space is limited. In terms of market space and capacity, the sapphire industry is still in its infancy. Simply put, it is currently the seller's stage, and there is no problem of not selling.
