Recently, the unveiling and launch event for the “Polarization Volume Grating (PVG) Waveguide Pilot Base” took place in Ji’an City, Jiangxi Province. The event was attended 

by Sun Litao, SEU Vice President, Wang Baoping, former Executive Vice President of SEU, and other other officials from Ji’an City.

The Head of Jinggangshan Economic and Technological Development Zone Management Committee delivered a speech, highlighting that the Ji’an Electronic Information 

Research Institute’s Industry Incubation Center is a key innovation platform. The successful launch of the PVG waveguide pilot production base marks a crucial step in 

strategically laying out emerging industries and seizing development opportunities, which will play a significant role in the development of the AR display industry.

In his address, Sun Litao emphasized that the establishment of the PVG waveguide pilot production line is an innovative practice aligned with the important directives on the 

integration of technological innovation and industrial innovation, as stated in the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China. It 

also serves as an effective exploration in cultivating new quality productive forces. He further elaborated on SEU’s innovative efforts in promoting the commercialization of 

scientific research achievements and pointed out that the breakthrough in PVG technology has broken the foreign technological monopoly. This not only positions China to 

take a leading role in the hundred-billion-level market but also has strategic significance in safeguarding the country’s industrial and information security in the future smart 

hardware ecosystem.

The PVG technology was first proposed by Prof. Zhang Yuning’s team from the School of Electronic Science and Engineering, SEU, in 2016. It is an AR waveguide technology 

that offers significant advantages over traditional technologies in terms of optical efficiency, battery life, and cost. In 2024, the research team launched the “Skylark” AR 

glasses, which, with a lightweight design of 45 grams and all-scenario adaptability, demonstrated the commercialization potential of the technology. The “Skylark 2.0,” 

upgraded in 2025, further showcases the rapid technological iteration and industrial vitality. The successful unveiling of the PVG waveguide pilot production base marks a 

significant step forward in the industrialization of China’s AR display core technology, opening a new chapter in the deep integration of government, industry, academia, and 

application.
