Nowadays, with the rapid development and in-depth application of the new round of information technology such as the Internet of Things, the Internet and cloud computing, the development of information technology is brewing major changes and new breakthroughs, and it has become an inevitable trend to develop to a higher stage of wisdom. In recent years, the state attaches great importance to the construction of smart cities in various aspects. As a positive response to policies and consideration of its own urban development, a number of cities in China have carried out the construction of smart cities in recent years. A large number of high-tech, information-based facilities and technologies represented by nano-touch, Internet of Things and big data have been acquired in the construction of smart cities. It has been widely used.
Faced with the harsh outdoor environment, high standards and strict requirements are put forward for the safety and stability of human-computer interaction convenience equipment. Compared with traditional touch technology, the principle of nano-touch screen is to place the nano-touch film under the surface toughened glass, so it can realize human-computer interaction without direct contact with the external environment. There are no exposed parts, no mechanical keys, and its service life can reach 10 years. Pure design, beautiful and generous, surface water, dust do not affect the touch, more than 4 mm toughened glass fight, high safety factor. It has the characteristics of waterproof, dustproof, fighting and other touch-control products, and is suitable for outdoor use in complex environment. It is an indispensable core part of future wisdom city construction and intelligent terminal integration. As the core component, it is used in large-scale production of vending machines as a secondary integration with specific outer frame and automatic vending parts. In addition, with the large-scale production of nano touch screen in small and medium size, the price is almost the same as that of infrared screen.
