It has been five years since the smart city was formally proposed by IBM in 2010, but in fact, it was first proposed in 2008. With the continuous development of human society, the city will bear more and more population cities in the future. The construction of smart city has become an irreversible historical trend of urban development in the world, which is of great significance in leading the application of information technology and improving the comprehensive competitiveness of cities.

In the past decade, with the joint efforts of the Chinese government and industry, semiconductor lighting (LED) has developed rapidly. At the same time, China's LED industry has made considerable progress in terms of the scale of its LED industry. However, with the pursuit of investment and the continuous diffusion of technology, the LED industry has rapidly changed from blue ocean to red sea. Only from the LED display screen, the product quality is uneven, the price war is fierce, and the standard is not perfect. In view of the starting point of building a smart city, if the LED display industry still stays in a relatively simple market, can not innovate technology, do not consider and layout application innovation, this industry will be replaced by other emerging industries sooner or later. In response to the call of smart city, the R & D team of Coriolis optoelectronics has developed many products with low energy consumption and high environmental protection.

Help development: innovation is not only the soul of national progress and development, but also the mission of semiconductor lighting. Each LED display screen is made up of "semiconductors". If every "semiconductor" can play its role in energy conservation and emission reduction, then the construction of smart city and the promotion of its sustainable development will achieve very considerable results. In recent two years, Decai optoelectronics has launched new LED products to help the development of smart city. For example, outdoor LED (DIP) P10, p16 display screen, its main features for low power consumption, low heat, low noise, energy conservation and environmental protection, its dual channel heat dissipation design, reduced, long life, stable system, safe and reliable use. Due to the complex outdoor environment, there are high requirements for the display terminal of digital signs. After continuous efforts and attempts, the Decai R & D team has designed a professional mask on the outdoor display terminal, which can prevent dust and water, and strengthen its ability to resist ultraviolet rays. It also adds anti deformation module package with good flatness, which ensures the best display effect of the screen.

In addition, calila tronics has installed supporting solutions for smart city, such as intelligent security system, command and dispatch system, traffic control system, intelligent management system, video conference system, customized industry application system, etc. through the application of small space display screen, it can effectively monitor and get timely information feedback, and truly realize "intelligent" control. The launch of indoor small space LED display P2 and p2.5 will play an important role in the construction and development of smart city in the future. Decai R & D team is creating and will put into the experiment: the LED display system with intelligent control function will be implanted into the most cutting-edge intelligent system. In the future smart city, the relevant managers can use the unified electronic control platform to make the display screen play the role of security monitoring and command center in the whole city to meet the requirements of public security management, urban management, traffic management and emergency response Command and other needs, but also can take into account disaster and accident warning, safety production monitoring and other aspects of the image monitoring needs, so as to ultimately complete the upgrading of urban services, and promote the comprehensive application and development of smart city.

As the only national high-tech enterprise without administrative division in LED display industry, calila tronics will become the leader of LED industry with its own capital, technological innovation and government resources.
