The new technology relies on what are called metasurfaces, which may be meant by “transformed surfaces”.
Technical researchers from (Nottingham Trent University) in England, (Australian National University) and (University of New South Wales Canberra) in Australia announced a new technology that may spark an industrial revolution in the world of screens and television.
The researchers explained that the technique relies on so-called metasurfaces, which may be meant as “metasurfaces” because they are made up of arrays of electrically tunable nanoparticles.
The researchers claim that the use of nanoparticle arrays instead of the conventional liquid crystal cells currently used in monitors and televisions will provide significant benefits, as nanoparticle arrays are up to 10 times smaller than liquid crystal cells, which leads to a dramatic increase in the density of image modules. or pixels, making graphics smoother and more realistic.
Professor Mohsen Rahmani, Head of the Laboratory of Advanced Optics and Photonics at (Nottingham Trent University) and a contributor to the project, told TechRadar: “The main factor determining pixel dimensions in LCD and LED screens is the limitation of technology. Liquid crystal, it is thick and cannot be too small and too close together due to overlapping of adjacent image units or pixels. But our technology is not limited to this.
The new technology also allows for very high levels of frequency rates, as “light can be switched approximately twenty times faster than the so-called ‘repulsion response time’ of the human eye, by changing the temperature of the material.” Displays using nanoparticle arrays are expected to reach frequency rates in excess of 1,000 Hz, far superior to anything currently on the market.
The technology also uses silicon, which results in a significant increase in screen life, lower production costs, and significantly lower power consumption. Switching to silicon also allows for ultra-thin cells that can reduce weight and thickness by up to 99 percent, paving the way for a much wider range of applications.
When asked about his expectations regarding the availability of this technology in the market, Professor Rahmani said: “With good investment, we expect it to be available within 5 years or so. Our technology is compatible with both LCD and LED production lines. Therefore, there is no need to develop a production line from scratch. We think it’s very easy, because technically, we just need to replace nanoparticle arrays with liquid crystal cells. The other layers within the screen (light source, color filters, etc.) will remain the same.
