Guangyu Yuanxin

Guangyu Yuanxin (光宇元芯) is a Hangzhou-based photoelectronics company specializing in Micro-LED microdisplay chips for AR and optical interconnect applications . The company has developed a selective area growth (SAG) process that grows III-V semiconductor materials directly on silicon wafers using photolithography-defined nano-scale pixel cavities, aiming to solve three industry bottlenecks: high-PPI microdisplays, red-light efficiency, and monolithic full-color integration . In its most recent financing, Guangyu Yuanxin closed consecutive Pre-A and Pre-A+ rounds in early 2026 totaling over RMB 100 million, led by Fangguang Capital with follow-on from Sequoia China, Xianghe Capital, and Zhongke Chuangxing; Fangguang Capital also reinvested in the Pre-A+ round . Linear Capital was the company's angel-round investor . The firm positions itself at the intersection of AR microdisplays and Micro-LED optical interconnects for AI infrastructure, two markets it sees as technically complementary though on different commercial timelines .
