Researchers at Zhejiang University in the Chinese mainland have set a new record by developing the world's smallest perovskite LEDs, achieving a pixel length of just 90 nanometers. Led by Di Dawei and Zhao Baodan, the team has harnessed innovative semiconductor technology to push the limits of device miniaturization.
The breakthrough study, published in Nature on March 19 under the title "Downscaling micro- and nano-perovskite LEDs," explores the process of "downscaling"—a key advance in the fields of computing, display technology, and human-machine interactions. By reducing the size of elementary devices, this technology opens doors to ultrahigh-definition photoelectric displays that are particularly promising for high-end augmented reality (AR) and virtual reality (VR) applications.
Traditional micro-LEDs typically suffer from a steep decline in efficiency when their pixel dimensions drop below 10 micrometers. In contrast, the newly developed micro- and nano-perovskite LEDs begin to show efficiency challenges only below approximately 180 nanometers, marking a significant edge over conventional technologies.
Although high manufacturing costs and intrinsic process challenges remain, this innovation lays a strong foundation for the next generation of display technologies. Future collaborations with industry partners are anticipated to drive these advances toward practical, real-world applications.
This pioneering work not only represents a leap in electronic device engineering but also promises to revolutionize display solutions across entertainment, business, and technology sectors worldwide.
