Suzhou Leiyu Semiconductor Group

Suzhou Leiyu Semiconductor Group (Raysolve) is a specialized semiconductor company focused on the design and production of full-color Micro-LED micro-display chips for the augmented reality (AR) market. The company was founded in 2019 by Dr. Wing Cheung (Eddie) CHONG and a core team with extensive experience in microchip design and manufacturing from the Hong Kong University of Science and Technology (HKUST). Dr. CHONG, who serves as CEO, and the founding team have a background rooted in decades of research in cutting-edge microchips. This academic and research foundation is central to the company's approach, which was highlighted when the team announced the first-ever single-chip full-color Micro-LED micro-display in 2019.

Raysolve's business model centers on providing key display components to manufacturers of next-generation consumer electronics. The primary clientele includes developers of AR glasses, but the technology also has applications in head-up displays (HUD), micro-projectors, maskless lithography, and 3D printing. The company has secured significant financing from a syndicate of venture capital and strategic corporate investors, including Meridian Capital, miHoYo, Source Code Capital, Gaorong Capital, Will Semiconductor, and AAC Technologies, to fund research and development and scale production.

The company's core product is a monolithic, full-color Micro-LED micro-display. Unlike competing solutions that often rely on bulky three-color synthesis or inefficient color filters, Raysolve has developed a proprietary quantum dot (QD) photolithography process. This technique involves using blue Micro-LEDs to excite red and green quantum dots that are patterned directly onto the GaN-on-Silicon wafer with semiconductor-level precision. This method bypasses common issues like mass transfer, enabling the high-yield production of small, energy-efficient displays on 8-inch wafers. The resulting micro-displays, such as the 0.13-inch PowerMatch® 1, deliver high brightness (up to 500,000 nits), a wide color gamut (108.5% DCI-P3), and are housed in an ultra-compact light engine (0.18cc), making them ideal for lightweight, all-day wear AR glasses.
