Coslight Yuanxin completed 2 rounds of financing to promote Micro LED micro-display research and development

Linear Capital reported on June 1 that recently, Coslight Yuanxin Optoelectronics Co., Ltd. completed two rounds of financing, Pre-A and Pre-A+, with a cumulative financing scale of more than 100 million yuan.

The Pre-A round was led by Fangguang Capital and Huarui Investment, with participation from Sequoia China, Xianghe Capital, China Science and Technology Star, etc.; the Pre-A+ round was continued by Fangguang Capital with additional investment. Linear Capital is its angel round investor.

Coslight Yuanxin was established in 2022 and is headquartered in Qiantang District, Hangzhou. It is a semiconductor company focusing on Micro LED microdisplay chips. It mainly provides ultra-high-precision microdisplay solutions for Yuanverse human-computer interaction devices such as AR and VR. The company takes three-color Micro LED chips and modules as its core product direction and is committed to improving display accuracy and integration.

Coslight Yuanxin adopts the SAG technology route to move the preparation of Micro LED to the material growth stage. SAG forms a nanoscale pixel growth area on a silicon-based wafer through photolithography, and then uses epitaxial equipment such as MOCVD to selectively grow III-V semiconductor materials in a preset area to form a light-emitting structure.

The SAG route is characterized by pixel-level control through wafer-level patterning, which can theoretically support higher pixel density. At the same time, this solution attempts to promote red light efficiency improvement and single-chip full-color integration within the same process system, but the related technology is still in the continuous verification and engineering stage.

Coslight Yuanxin has completed multiple rounds of angel round financing in 2022 and 2023, with investors including Sequoia China, Linear Capital, Mingshi Capital, China Science and Technology Star, etc.; it will complete Series A strategic financing in 2025, led by Huarui Investment. In March this year, the company completed its industrial and commercial changes and added new shareholders such as Xianghe Capital, China Science and Technology Star, and Fangguang Capital.
