Nicholas Colaneri, director of the Flexible Display Research Center at Arizona State University, said that the presence of bendable screens does not mean that bendable devices will appear on the market in the next few years. He said: "Display panels are only a small part of the revolution. Auxiliary electronic components, power supplies, and circuits that can be fully bent are not yet in mass production." Nicholas Colaneri says we'll see bendable screens on the market within three to five years - but that's just screen technology. Other components are a bit further off. The first products to use this screen will be larger external displays rather than smaller readers. Other news shows that Samsung is also working on the research and development of bendable screens and is expected to launch a mobile phone or tablet with a bendable screen in 2012. At the same time, Samsung has demonstrated its first 4.5-inch bendable screen smartphone at CES 2011, but it is not the first mobile phone to display a bendable screen. If scientists can perfect tungsten diselenide diodes, countless scientific ideas that are currently impossible to achieve will be realized. Flexible transparent displays will be able to be used in car windshields or smart devices such as glasses and contact lenses.
Research into new materials often focuses on perfecting one technology, but a new study improves the capabilities of multiple technologies by making better diodes, which will have implications for the entire field of optoelectronics, including photovoltaic cells, light-emitting diodes, and optoelectronics. The detector has an impact. Researchers are now exploring the use of ultrathin "2D" semiconducting transition metals to create flexible, ultrathin electronic devices.
Flexible solar photovoltaic panels and OLED screens have already appeared. But the materials currently being studied are thinner and more usable. A diode that is only one molecule thick will fundamentally change the technology in the field of optoelectronics. Displays, sensors and solar cells will cost more and have a wider range of applications, and may even be used in clothes in the future. The study was jointly completed by researchers from the Massachusetts Institute of Technology, the Technical University of Vienna, and the University of Washington. The research team mainly studied tungsten diselenide materials. The material is a crystal structure consisting of a single atomic layer of tungsten sandwiched between two layers of selenium. This structure makes tungsten diselenide an extremely durable material even when thinned. Fortunately, the technology used to split graphene also works with tungsten diselenide, so producing this semiconductor diode is not too difficult. A diode is a semiconductor device that allows current to flow in one direction. There are two types of semiconductor materials used for diodes, one is P-type (Positive, positive electrode) and the other is N-type (Negative, negative electrode). Only one of the two can be chosen because the properties of the diode are based on, for example, the germanium or boron atoms doped in the base material. Ultra-thin diodes made of tungsten diselenide do not suffer from the above limitations. These materials can switch between P-type and N-type as needed. Applying this thin film layer to metal electrodes allows the charge state to be controlled entirely electrically. It can also be applied to any surface for folding. This material has broad application prospects and can be used to produce three types of optoelectronic devices (photovoltaic cells, light-emitting diodes and photodetectors). If scientists can perfect tungsten diselenide diodes, countless scientific ideas that are currently impossible to achieve will be realized. Flexible transparent displays will be able to be used in car windshields or smart devices such as glasses and contact lenses. We will usher in the era of cheap flexible solar cell technology. If safety can be ensured, these technologies can even be used on the skin. Who doesn't want a cool arm display device? There are various signs that whether Nicholas Colaneri's bendable screen is first used in external monitors or some manufacturers such as Samsung have launched mobile phone concept products, it all indicates that the second revolution in the LCD industry is just around the corner. If the price and productivity of the product are not taken into account, I believe that bendable screen displays will appear in the near future. However, the popularity of this type of monitor is expected to take more time than CRT being replaced by LCD monitors.
