Sapphire substrates for LED are used as a starting material. They are used in nitride-based LEDs. The two main advantages of sapphire as a substrate is that there is existing industry expertise in the production and use of sapphire and that there is a high availability of low-cost sapphire that enables the production of inexpensive LEDs. The sapphire substrate was used in military applications in the 1960s. The material is the preferred choice when it comes to using sapphire substrates for LEDs.
The sapphire substrates for LED is ideal for use not just in LEDs but also in non-LED applications due to its high-temperature resistance, good electrical insulation, high strength, and low dielectric loss. This substrate helps in preventing stray currents that are caused by radiation from spreading to the other circuit elements nearby. The high strength of the sapphire substrates for LEDs make it more scratch-resistant and hence suitable for covering lenses, buttons, displays for non-LED applications like smartphones. The global sapphire substrates for LED market continues to increase due to the lower yield, lattice mismatch and falling prices of sapphire wafers.

And based on the varying applications, the global sapphire substrate for the LED market can be classified into Mobile Phones, Tablets, and other applications. The key players in the market are focusing on the expansion of manufacturing sites, capacity, production, revenue, opportunity and the challenges faced by the emerging companies in the sapphire substrates for LED market.
Countries like Japan, China, India, and regions like Europe, North America, and Southeast Asia are the rising centres for the sapphire substrates for LED market. The report studies the production, consumption, import, and export of sapphire substrate at a global scale. The ease of availability of the raw materials and equipment suppliers coupled with a low labour cost has also been some of the key factors contributing towards the boost of the global sapphire substrates for the LED market. However, the recent rise in the silicon substrate and GaN substrate usage due to their ability to combine the LED optical parts hence increasing the LED product efficiency has hampered the growth of the product. Many manufacturers are focusing on cutting the cost and the intensification of the price war of the sapphire substrate has led to a reduction in the product market growth.
OSRAM Licht AG, a German multinational lighting manufacturer has introduced two LED chips named the Firefly SFH 4030 and SFH 4060 LEDs for use in virtual and augmented reality (VR/AR) that will prevent the feeling of discomfort or dizziness for people suffering when using AR and VR glasses. These chips will track eye movements providing a targeted point of reference.
