Recently, Nanjing Parallel Horizon Technology Co., Ltd. ("Parallel Horizon"), a directly invested enterprise of Nanjing Innovation Investment Group, announced that the world's first pilot production line for Polarization Volume Grating (PVG/PVH) waveguide independently constructed by the company has been officially put into operation. This significant milestone marks the successful key leap of the original core technology incubated by Southeast University from the laboratory to large-scale production, injecting strong impetus into the development of the AR (Augmented Reality) display industry.

The pilot production line has an annual capacity of 50,000 pieces, with a stable yield rate of over 80%. The company has laid out 84 national invention patents and multiple international patents. Its products cover monochromatic/color one-dimensional and two-dimensional waveguide sheets as well as complete modules, with application fields expanding to vehicle displays, medical imaging, and other areas. With the gradual maturity of mass production processes and the rapid growth of market demand, the mass production line with a planned annual capacity of 500,000 pieces by Parallel Horizon has also started planning and construction.

The PVG waveguide technology was originally developed by the Southeast University team in 2016. It boasts advantages such as high optical efficiency (3000 nits/lm), low manufacturing cost (60% lower than traditional solutions), and a large field of view (60°), with backward diffraction less than 3%. It is compatible with various substrates and can significantly improve the clarity and immersion of AR displays. In 2024, the company cooperated with Luxshare Precision to launch "Lark", the world's first PVG waveguide AR glasses, verifying the feasibility of mass production of the technology.

Founded in January 2022, Nanjing Parallel Horizon Technology Co., Ltd. is committed to the R&D of AR waveguide technology. The company's independently developed Polarization Volume Grating (PVG) technology holds a prominent innovative position in the industry. The founding team is led by Professors Zhang Yuning and Weng Yishi from Southeast University, and includes many senior experts in the field of display technology with profound technical accumulation and industry experience. The company was selected into the "China VR/AR Top 30 Enterprises" list in 2024.

In November 2022, Nanjing Innovation Investment Group completed an angel round investment of millions of RMB in Parallel Horizon, with the funds mainly used for the construction of the company's high-level team and the expansion of the pilot production line. The relevant person in charge of the Fifth Investment Department of Nanjing Innovation Investment Group stated that the commissioning of the pilot production line is a key milestone in technology industrialization. This not only verifies the maturity of the technology and the feasibility of mass production, but also clears key obstacles for the popularization of consumer-grade AR products with core advantages such as ultra-high luminous efficiency and ultimate cost-effectiveness. It will help seize the commanding heights in the global competition of the new display industry, and the Group is full of expectations for the company's future growth and value.
