German scientists create the smallest pixel in the world: a revolution for displays.

According to Korrespondent.net: Researchers from the University of Julius-Maximilian in Würzburg (Germany) developed the smallest pixel in the world, measuring just 300 by 300 nanometers. This is more than ten times smaller than the pixels in modern microOLED panels, reports Tom's Hardware. If these pixels were used to create a screen with a standard resolution of 1080p, its diagonal would be just 1 millimeter.

The new OLED technology

The development is based on a new version of organic light-emitting diode (OLED). Scientists created a metal contact that not only injects current but also amplifies light emission. This allowed achieving brightness equivalent to that of a regular 5x5 micrometer OLED pixel.

Professor Bert Hecht, one of the study's authors, reported this.

Prospects for using nanopixels

These nanopixels have the potential to revolutionize the creation of ultra-compact displays for augmented reality glasses, smart gadgets, and medical devices. They not only reduce weight and energy consumption but also provide an incredible image density, potentially thousands of times higher than current screens.

Improving the technology

To ensure stable operation, the team made changes to the OLED structure: around the gold antenna, the heart of each diode, scientists added a special insulating layer. This prevents metal leakage into the organic material and short circuits. In this form, the nanodiodes operated stably for two weeks of experiments.

The next step will be to expand the color gamut to the full RGB spectrum and improve efficiency, which currently stands at only 1%, making this technology too energy-consuming for practical use.

If scientists succeed in refining this technology, it will pave the way for creating ultralight displays with super-dense images that can be integrated into any devices.

It was previously reported that a memory chip the thickness of one atom was created in China.
