en.Wedoany.com Reported - A research team led by Professor Li Fushan from the College of Physics and Information Engineering at Fuzhou University in China, in collaboration with the Mindong Innovation Laboratory, has made significant technological progress in the field of ultra-high-definition integrated displays. On April 2, 2026, Beijing time, the team published a research paper in the journal Nature, unveiling an ultra-high-resolution quantum dot display technology for augmented reality (AR) and virtual reality (VR) applications. This technology addresses a major industry challenge—the precise fabrication of pixel patterns at micron and nanoscale—through a novel nanofabrication process.

To tackle issues such as color crosstalk and performance degradation in traditional manufacturing methods, the research team developed a nanoscale printing technique. This process enables the precise positioning of luminescent materials at extremely small scales, constructing defect-free red, green, and blue pixel arrays. By optimizing material distribution and structural design, the approach effectively eliminates signal interference between pixels and introduces nanoscale materials to regulate internal charge within the device, thereby enhancing overall luminous efficiency.

Test data show that the red-light device fabricated using this ultra-high-resolution quantum dot display technology achieves an external quantum efficiency of 26.1% and an operational lifetime exceeding 60,000 hours. The performance metrics for green and blue light devices have also improved compared to previous solutions. Professor Li Fushan stated, "As AR and VR devices evolve toward higher resolutions, 'retina-level' displays require pixel densities exceeding 10,000 PPI. Our research provides a viable path to achieving this goal."

Currently, researchers including young faculty member Lin Lihua from Fuzhou University have integrated this technology with integrated circuits, successfully developing a prototype integrated display capable of controlling individual pixels and achieving dynamic image display. This achievement supports China's independent development in the next generation of integrated display and related chip technologies. In the future, this ultra-high-resolution quantum dot display technology is expected to be applied in the manufacturing of high-end display chips and micro-displays, driving the display industry toward higher color accuracy and longer lifespan.
