Several tech companies but also scientists are focusing a lot on future of displays. The smartphone screen, in particular, is the center of attention. This is still too expensive in terms of energy and with the advent of folding screens the matter gets complicated. However, one new solution was found by the sicenziati of KIMM Department of Nanomechanics. It is a flexible, extensible screen that does not distort the image quality. Let's see the details.
The future of displays is bright: scholars have developed a foldable and extendable screen that does not lose image quality
The scientists reached this goal with the help of design technologies and metamaterials with unique physical properties. As a result, the image on the three-inch micro-LED display it is not distorted, regardless of how long the display is stretched. In technical terms, the secret lies in the metamaterial with a negative Poisson's ratio in the printed circuit board. In other words, when such a material is stretched in length, a proportional effect of stretch in width also occurs.

Based on the results of this project, the senior researcher team Dr. Bongkyun Chan and his research team from KIMM's Department of Nanomechanics intend to further research on micro-LED displays. New technology should too diversify mobile platforms such as smartphones and tablets, since such a screen is capable of fit and adhere to the skin, opening up opportunities for applications in medical and cosmetic devices.
The project was presented during the "Development of Micro LED Meta-Display Technology", Carried out in 2019 as part of the program Global Frontier of the Ministry of Science and ICT with the support of the Center for Advanced Metamaterials (CAMM). KIMM's Department of Nanomechanics is engaged in research in the field of micro-LED transfer technology twigs 2008.
