Scientists utilize nano technology to create nano-PeLEDs for establishing high-resolution screens that enhance gaming and augmented reality as well as medical visualization applications.

The scientific team consisting of researchers from Zhejiang University and the University of Cambridge introduced nano-PeLEDs which hold the title of being the smallest ever LED developed in nano technology. The fabrication of LEDs based on perovskite materials at 90 nanometer pixel dimensions produces exceptional 127,000 pixels per inch resolution which outperforms the capabilities of typical micro-LED displays.

In his lecture at Zhejiang University Professor Di Dawei stressed that nano technology delivers both increased device efficiency and miniaturization. Nano-PeLEDs maintain their operational efficiency because they are composed of halide perovskites while standard micro-LEDs lose their performance at microscopic size levels.

Creating nano-PeLEDs required additional development because perovskite materials tend to fall apart easily. The researchers implemented a new lithographic fabrication process which safeguarded the breakable material without compromising image quality.

The commercialization of nano technology at Zhejiang University is being driven through its partnership with LinkZill who are a Hangzhou-based TFT technology specialist firm. The micro-PeLED display offered by their prototype illustrates product potential for both gaming systems and augmented reality devices and medical image inspection.

Nano-PeLEDs are expected to transform display technology through their evolving nano technology capabilities which create prospects for extremely high-resolution screens in electronic devices.
