The appearance appearance: The reducing the driving force in technological progress-enhancing computing power through smaller transistors to the progress of display technology with young people. Now, researchers from the University of Zhejiang and the University of Cambridge are pushing the boundaries of innovation that leads to that, and reveal the smallest LED lamps in the world: Nano, based on the semiconductors of Peruviskite.
This nano features small pixels of up to 90 nm, allowing an unprecedented pixel density of 127,000 pixels per inch (PPI). For comparison, the 27 -inch Typical Games screen has a pixel density of 163 points per inch.
“Making electronic devices smaller is the eternal chase of scientists and engineers,” he said. Prolibssoror is the end.Deputy Director of the International Equestrian Research Center at the University of Zhejiang.
He explained that although the semiconductor-based semiconductors are semiconductors, their efficiency decreases sharply when pixel sizes decrease to less than 10 ومتر m-which hinders their use in high-resolution displays.
Unlike traditional small horses, nano displays the minimum performance deterioration even in microscopy. This flexibility is attributed to its unique composition: Halide Pervakets – a group of semiconductors associated with solar cells more common. “Halide Pervakett is a new category of semiconductors,” said Professor Zhao Budan of the University of Zhejiang.
However, the creation of Nano designers was not a simple task. Perovskite materials are fragile and badly for damage during traditional optical processes used in LED style screens. To overcome this, the research team has developed a new manufacturing method that includes latjogographic windows in a insulating layer. This technique protects perovskite sensitive substance while maintaining high image quality.
Lyan Yaxio, the first author of the study, published in “traditional optical operations”, said not suitable for the direct pattern of Perovskite classes – it will harm the materials. nature. “This problem is overcome by the translated communication manufacturing scheme.”
The team showed that the nano archives close to infrared have maintained external quantitative competencies of about 20 percent through pixel sizes ranging from several hundred microbes to only 3.5 microns.
Even in extreme miniaturization-approximately 180 nanometers-the decrease in efficiency was much lower than those seen in traditional small horses. This indicates that Nano viewers can outperform the II-V small conductors based on semiconductors in applications that require super pixel units.
While Nano viewers offer a huge promise of high -resolution display screens, practical implementation requires integration with vulnerable circles capable of delivering dynamic content. To this end, the University of Zheyang has a partnership with Linkzill, a Hangzhou -based company specialized in Thin Film Transistor (TFT) technology.
Together, they developed a preliminary display of Microshin paid with a TFT background. This initial model is essential to marketing technology covered with nano, abolishing its potential for complex images and playing video.
As researchers continue to improve this technology, its potential applications are rapidly expanding. It can redefine the criteria for display across various industries-from games and augmented reality to medical photography.
