On Friday, a group of British scientists from the University of Cambridge published an article in Science Advances magazine about the development of promising technology for the production of relatively inexpensive screens of almost unlimited size. Do not be confused by the mention of a Friday and British scientists who have scolded the mouthwash. Everything is honest and serious. The study is based on the study and use of the long-known plasmon quasiparticles within the framework of the physical phenomena of plasmonics. In short, plasmons represent a cloud of electrons on the surface of a material. They possess certain collective properties and, depending on a number of factors, can emit light in the visible range with a given wavelength (color).
Scientists from Cambridge have developed a technology for mass production of plasmon-based screens. The smallest particles of gold were covered with conductive plastic polyaniline and evenly sprayed on the plastic surface with a mirror coating previously applied on it. Each granule of gold on the surface is the basis for a miniature pixel, the dimensions of which are a million times smaller than that of the screens of modern smartphones. The technology is very simple for mass production, as the developers insist. Such screens with billions of pixels per meter can be released with continuous tape at high speed. We are talking about the production of flexible displays literally the size of the wall of a multistory building.
Light falling on such a screen falls into a trap between plastic-coated gold nanoparticles. Conductive plastic coating under the influence of the control voltage in a given way changes the chemical properties and causes a change in the wavelength of the reflected light in a wide spectrum (the wavelength can be reduced to 100 nm or less). The pixel begins to glow in a given color and, importantly, such a bistable state that it does not require power to hold the selected color.

Prospects for such screens are huge - from information to camouflage. The highest resolution will allow to hide the fighter even in open areas, and the use of the architecture will open the way to new and unusual solutions. Displays for electronics will also receive an impetus to development. They will be well read in bright sunlight and will cease to be the most active battery charge eaters. But before that there is still a long way to go, improving and developing technology. In particular, the team of scientists began to work on expanding the color range of displays based on the technology presented. Read more about the development in the article in Science Advances.
