In the past decades, with the rapid development of military optoelectronic/infrared systems, people have put forward higher requirements for large area optical windows, and the demand for optical materials with high hardness, high strength and high transmittance is becoming more and more intense. Sapphire material has a high Mohs hardness of 9.0 and high transmittance in both visible and infrared bands, so it has become the preferred material in the extreme use environment.
As an important technical crystal, sapphire can be widely used in military, aviation, electronic consumer products and other fields. Sapphire application has broad prospects, especially in the field of electronic consumption and LED basic applications.
With the continuous improvement of sapphire production technology and the continuous reduction of production cost, in addition to the previous application of LED basic panel, sapphire has been widely concerned by various industries in recent years, and all countries in the world are optimistic about the business opportunities of sapphire substrate.
Patterned sapphire substrates are mainly used in the production of led sapphire wafer materials, with high hardness, high dielectric coefficient, high thermal conductivity and other advantages. In addition to smartphones and wearable devices, it also includes camera lens protection cover and main screen key of apple, Samsung, LG and other high-end smartphones. Patterned sapphire substrates are expected to be applied in optics, aerospace science and technology, military and other fields.
