In Wuhan, the main assembly of a full-size G6 inkjet printing system for next-generation displays was recently completed. Capable of controlling hundreds of millions of ink droplets with micrometer-level precision, this equipment showcases China’s leadership in the global display race. The system was developed by Professor Yin Zhouping and his team from the School of Mechanical Science and Engineering at Huazhong University of Science and Technology (HUST).

Yin, elected as an academician of the Chinese Academy of Sciences on Nov 21, has spent over 20 years advancing high-end chip and display manufacturing technologies. Inspired by China’s reliance on imported display equipment early in his career, he led his team to develop domestic next-generation display printing technologies.

The inkjet printing process increases the material utilization rate to 90 percent, reduces material costs to a mere third of traditional methods, and allows screens of unlimited size to be produced under normal temperature and pressure. These innovations have been applied at leading global companies like TCL CSOT.

The team also advanced precision chip bonding techniques, enabling transitions from single-chip to wafer-level and square-meter scale production. Their work supports China’s self-reliance in integrated chip manufacturing and has resulted in over 100 high-performance intellectual property applications.

Yin’s breakthroughs extend to humanoid robots. His team’s electronic skin sensors can detect minute changes in pressure and temperature, withstanding up to one million presses. Hundreds of sensor points analyze pressure in just 0.1 seconds, enabling robotic joints to adjust force instantly. These sensors are produced using roll-to-roll printing technology and are applied to 70 percent of China’s major smart manufacturing projects and 28 global lighthouse factories.

The School of Mechanical Science and Engineering emphasizes the “Striving, Teamwork, Agility, Responsibility” (STAR) culture that has inspired generations of scientists. Dedicated to talent cultivation, Yin has pioneered advanced electronics manufacturing undergraduate programs at HUST, established key national teaching platforms, and built the STAR Innovation and Research Fund to support young researchers.

Reflecting on the country’s goal to become a strong nation in science and technology by 2035, Yin stresses the urgency and honor of their mission. “Only through firm determination and relentless effort can we shoulder this responsibility,” he said.
