On the 2nd, it was learned from Fuzhou University that the university has made a breakthrough in the field of ultra high definition integrated display technology in collaboration with the Mindu Innovation Laboratory. Led by Professor Li Fushan's team from the School of Physics and Information Engineering at Fuzhou University, they have successfully developed an ultra high resolution quantum dot display technology for augmented reality (AR) and virtual reality (VR). The relevant research paper was published on April 2nd Beijing time in the top international academic journal Nature. Li Fushan introduced that with the rapid development of technologies such as AR and VR, display devices are evolving towards higher resolution, more realistic colors, and longer lifespan. Among them, "retina level" displays (pixel density exceeding 10000) are considered a key target, but when pixel size is reduced to the micrometer or even nanometer scale, traditional methods are difficult to accurately prepare patterns, colors are prone to mutual interference, and device performance significantly deteriorates, becoming a core challenge for the development of the manufacturing industry. In response to this issue, the research team has proposed a new nanomanufacturing method that can achieve "precise printing" of luminescent materials at an extremely small scale, constructing high-precision red, green, and blue pixel arrays with almost no defects in the patterns. Meanwhile, by optimizing the material distribution, the luminescence is more uniform and stable, and the structural design effectively avoids interference between different colors, resulting in a significant improvement in display quality. The team also introduced nanomaterials to regulate the internal structure of the device, significantly improving efficiency and lifespan. The first author of the paper, Lin Lihua, a young teacher from Fuzhou University, introduced that with the support of multiple technological innovations, the efficiency of the red light device prepared by the team reached 26.1%, the lifespan exceeded 60000 hours, and the performance of green and blue light devices was also significantly improved. Furthermore, the research team combined this technology with integrated circuits to develop an integrated display prototype that can control pixels one by one, achieving dynamic image display and providing a new path for the development of high-end integrated display chips. Experts say that this achievement provides important support for China's independent development in the field of new generation integrated display and related chip technology. (New Society)
