1. Market value of sapphire
Sapphire, commonly known as corundum, is mainly composed of alumina (Al2O3). The crystal hardness of sapphire is high, and its Mohs hardness is grade 9, only behind diamond. At the same time, sapphire has good light transmittance, thermal conductivity and electrical insulation, good mechanical properties, wear resistance and corrosion resistance. Its upstream industry is basic materials industry and equipment such as alumina, tungsten and molybdenum, and its downstream industry is sapphire substrate materials and consumer electronics products. With the rapid development of LED industry, LED will still be the mainstream application market of sapphire. As the main substrate material, sapphire substrate is expected to benefit from the development of Micro LED industry and has a broad market prospect.
2. Sapphire in LED market
Sapphire market scale continues to grow, sapphire substrate in LED substrate application market share of about 80%. From the perspective of sapphire downstream applications, the main application field of sapphire materials is LED substrate materials, accounting for 79%, followed by mobile phone home button and camera applications, accounting for 15%, and other applications, accounting for 6%.
At the same time, with the development of LED downstream applications, sapphire substrates are expected to benefit from the development of Micro LED industry. First of all, LED lighting keeps a steady growth of about 10% every year, which drives the demand for sapphire to grow steadily. Secondly, Micro LED, as a new generation of display technology after OLED, has the advantages of wider perspective, higher contrast, better image quality, lower cost, seamless splicing and so on. All manufacturers are optimistic about its market prospect. Existing manufacturers have made technical layout in this field for many years, and Micro LED is expected to be the first to enter the wearable device market, giving rise to more demand for upstream sapphire substrates.
