Westlake Smokey Mountain Technology

Established in 2022 in Hangzhou, China, Westlake Smokey Mountain Technology (WSM, also known as Yanshan Technology) , develops and produces microLED chips targeting both microLED microdisplays for AR and VR applications and direct-view large-area microLED displays.

WSMT's technology is based on a vertically-stacked RGB microLED architecture, developed at Hangzhou's Westlake University.

In early 2025, the company announced plans to build an 8-inch GaN-On-Silicon microLED epiwafer production line in Huzhou, Zhejiang Province, China. In July 2025, the company raised its pre-A series funding round, at almost 100 million Yuan (around $14 million USD). In May 2026, the company started trial operation at its microLED fab in Huzhou.
