On the 2nd, it was learned from Fuzhou University that Professor Li Fushan's team has made significant breakthroughs in the field of ultra high definition integrated display technology, successfully developing an ultra high resolution quantum dot display technology for augmented reality (AR) and virtual reality (VR), which is expected to provide a new path for the development of high-end integrated display chips. The relevant results were published online on the 2nd in the 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" display, where pixel density exceeding 10000 is considered a key target. However, when the 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 decreases, becoming a core challenge that restricts the development of the 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 made more uniform and stable, and the interference between different colors is effectively avoided through structural design, significantly improving the display quality. The team also introduced nanomaterials to regulate the internal structure of the device, making the current distribution more uniform, thereby significantly improving efficiency and service life. Supported by multiple technological innovations, the team has developed a red light device with an efficiency of 26.1%, a lifespan of over 60000 hours, and significantly improved green and blue light performance. At the same time, researchers have combined this technology with chip circuits to develop integrated display prototypes 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.
