China-based microLED microdisplay developer Star Key Semiconductor has completed its latest funding round, raising over 1 billion RMB - or around $150 million USD. The round was led by CATL’s Puquan Capital, with participation from Meituan Longzhu, Guotai Haitong, Youshan Capital, CDH Hong Kong, and two (Chongqing and Jiangsu) state-owned investment firms.
In December 2025, Star Key inaugurated its microLED production line in Wuhan. This line is based on 8-inch GaN-on-Silicon microLED wafers, and will produce microLED microdisplays. The yearly capacity is around 12,000 wafers.
Star Key completed its previous round only a few months ago, raising "hundreds of millions of yuan", which likely means something between $30-100 million USD.
