A joint city light show with the theme of "Expressing love to the Motherland" illuminates 25 landmark buildings in nine cities along the Yellow River on September 16, 2019.

　　According to pictures of light shows of several landmarks (Wangfujing Department Store in Downtown Xining, Yellow River Bridge in Xiaoxihu, Lanzhou, Yuewan Central Business District in Yinchuan, Kangbashi Library and Museum in Ordos, East International Building of Yingze Bridge in Taiyuan, Zhengzhou Olympic Sports Center and Qianxi Square, Jinan Greenland Center) published by People's Daily Online, With the exception of the Yellow River Bridge in Xiaoxihu in Lanzhou and yuewan Central Business District in Yinchuan, other landmark buildings have applied LED transparent screen technology.  

 

　　LED display because of its characteristics of spontaneous light and bright colors and to meet the demand of the scenic spot of light at night, as a result, although the urban nightscape lighting still is given priority to with means of lighting, but because the light is far lower than the LED display brightness change and operability of the diversity, so the LED display screen still play a large role, and it can not restricted by advertising for examination and approval of features, Also makes it more and more favored by all kinds of buildings, such as New York Times Square, Shanghai Bund, Pearl River night view, etc. In addition, in recent years, many landmark buildings are installed LED screen, used for viewing, publicity, advertising and other purposes, but also brought many business opportunities for LED screen. And, now LED sky screen, LED tunnel screen, LED shaped screen and other novel, beautiful LED screen, its eye attraction is doubled, and the demand in the night tour economy will continue to rise. Compared through the means of lighting and beautiful surroundings, LED display black screen only when off the air, will affect beautiful during the day, and will affect the daylighting of the installation of the building, and because the traditional LED display need add steel frame, the weight is bigger, such as the construction process of installation position reserved ahead of time, late installation must consider the building bearing problem, Therefore, they are often limited in size and cannot play a greater role in the night tour economy.

　　For LED transparent screen, the daylighting problem that restricts the traditional LED screen is solved because of its transparency. In addition, its weight is much lower than that of the traditional LED outdoor large screen. Therefore, compared with the screen size, the size of LED transparent screen is only determined by the surface area of the building. Even completely replace the building exterior wall glass decoration, although LED transparent screen there is the contradiction between "permeability and clarity it too", but because of the huge transparent screen viewing distance is usually far away, so the LED transparent screen in clarity and conflict between the permeability of the impact of the basic can be neglected for the influence of building transparent display, However, with the progress and development of technology, this contradiction is gradually being resolved, the importance of transparent screen in landscape construction and building construction is increasing, the trend of LED transparent screen building materials is becoming more and more obvious, for example, the intelligent glass display screen developed by China Energy Conservation Institute has been comparable to real glass in permeability, And it can be used as a building material just like ordinary glass. And because it can fully fit the outer walls of buildings, it can better increase its artistry when applied to buildings with irregular outer walls (such as Kangbashi Library and Museum in Ordos, and Zhengzhou Olympic Sports Center) because of the irregular effect generated by the changes in the surface shape of the building.

　　As cities pay more and more attention to air environment and urban safety, more and more cities begin to replace fireworks with light shows as a way to celebrate the festival or make them a regular display of tourist attractions. In addition to not polluting the air, light shows offer a level of safety, variety and continuity that fireworks can't match. And as the night tour economy expands the city's profit time to the whole day, the LED transparent screen is also obvious in the pull and drainage of the night tour economy. So, so in the future urban development, the transparent LED screen has a hidden body during the day to shine at night natural advantages, is in the night landscape construction and holiday celebrations, etc to find belongs to own the exclusive positioning and development space, believe that as time goes on, there will be more and more city landmarks to install the LED transparent screen, Complete the transformation of combining landmarks and scenic spots into one.
