1. Overview of Sapphire Development

·Artificial sapphire was born in 1892

·Sapphire was first applied to watch screens in 1929

·In 1970, chips with long silicon on sapphire substrates were introduced

·In 1992, sapphire substrates were first applied to blue light LEDs

·Sapphire's first round of LED applications in 2000: mobile phones

·The second round of sapphire application in LCD TVs in 2010

·Sapphire entered the consumer electronics field in 2014

2. Sapphire characteristics

High wear resistance, high light transmittance, high dielectric constant, and good conductivity.

Sapphire has obvious advantages in mechanical, optical, and electrical properties compared to reinforced glass such as Corning, and is gradually becoming a new favorite of smart terminal protection glass materials.

3. Sapphire application field

The main component of sapphire is aluminum oxide, and its hardness is second only to diamond in natural materials.

Sapphire is currently widely used in fields such as LED substrates, consumer electronics protective glass, aerospace equipment, and medical implants.

4. Development trend of sapphire products

From the performance advantages of sapphire, the LED lighting field, and the differentiated demand for smartphones, it can be seen that the sapphire industry has been in a long-term development trend. In the future, both growth momentum and space are available, and consumer electronics and applications will become new growth drivers for the sapphire industry.

The future sapphire industry will present the following trends:

LED sapphire substrates will gradually evolve towards larger sizes;

The coexistence of multiple crystal growth methods and the quality of technology have become the industry watershed;

The layout of the industrial chain tends to be balanced, and the integration of upstream and downstream is intensifying;

Emphasize the layout of intellectual property rights and further improve the industrial environment.
