Scientists from the consortium of the NTI Competence Center “Photonics” from Alferov University, the Institute of Chemistry of St. Petersburg State University and Peter the Great St. Petersburg Polytechnic University have developed a film for displays. The peculiarity of the film is not only that flexible displays can be made on its basis, but also in the possibility of self-healing.Discuss
As experts said, the film is made of phosphors, special substances that can emit visible light under certain conditions. For example, they can be illuminated with ultraviolet light and, by choosing the composition of the phosphor, you can get any color.
Materials based on phosphors are used in advertising, design, cinemas, optoelectronics, biomedicine and other industries. But they can also be used to create and repair displays of computers, smartphones and TVs.
At the same time, films developed by Russian specialists can self-repair. To do this, it is enough to remove the damaged film from the display, heat it up to 100 degrees Celsius. This solution is suitable for repairing broken or cut screens.
“One of the important properties of the developed silicone phosphors is self-healing,” said Regina Islamova, professor at the Department of Macromolecular Chemistry at St. Petersburg State University.
