San’an Optoelectronics is China's largest LED epitaxial wafers and chips producer. San'an says it produces over 24 million epitaxial wafers and 300 billion LED chips annually - which is about 58% of the total production in China.

In 2018 San'an signed a long-term agreement with Samsung to co-develop and supply LED chips for Samsung's Micro-LED displays.

In 2019 San'an announced plans to setup a $1.8 billion Mini-LED and Micro-LED production center in Hubei, China. In 2020, TCL CSOT and San'an Optoelectronics agreed to co-develop micro LED materials and production processes and equipment, in a 300 million Yuan (around $43 million USD) investment.
