From the upstream of LED, the degree of concentration is accelerated, and higher industry barriers are formed, and the disordered capacity expansion is curbed. At the same time, downstream application innovation drives the development of the industrial chain. From the current situation, LED lighting accelerates penetration, LED lighting intelligent, networked to promote the accelerated emergence of small-pitch display market, becoming the main driving force for the new round of LED industry growth. Sanan Optoelectronics recently issued a price increase notice, raising the price of S-30MB/S-32BB series products by 8%, which started the first shot of LED chip price increase in 2017. From the upstream of LED, the degree of concentration is accelerated, and higher industry barriers are formed, and the disordered capacity expansion is curbed.

From the current situation, LED lighting accelerates penetration, LED lighting intelligent, networked to promote the accelerated emergence of small-pitch display market, becoming the main driving force for the new round of LED industry growth. According to the agency's calculations, by the end of 2017, the effective production capacity of LED chips is about 83.28 million pieces, and the demand is about 92.35 million pieces. The industry believes that LED chip production capacity is still below demand. Considering the steady growth in demand in 2017, LED chips will be in short supply.
