Along with the proliferation of outdoor advertising LED displays, a series of negative issues are produced, including the image of the city. When the LED display is working, it can really function to brighten the city and release information. However, when it is “resting”, it seems to be a “scar” of the city, which is incompatible with the surrounding environment and greatly affects the beauty of the city , destroying the scenery of the city. Due to the emergence of these problems, the approval of outdoor large-screen installations has become more and more cumbersome, and the management of outdoor advertisements has become more stringent. The transparent LED display not only integrates all the advantages of a conventional outdoor HD LED display, but also minimizes urban aesthetics. Because it is installed behind a glass curtain wall, it does not affect the surrounding environment even when it is not working during the day. At the same time, because it adopts a new form of indoor advertising with outdoor communication, it has circumvented the approval of outdoor advertising. In addition, with the acceleration of urban construction, the glass curtain wall, which is a high-end atmospheric grade building material, has gradually become popular. The transparent screen is characterized by its light weight, no steel frame structure, simple installation and maintenance, and good permeability. It is a perfect match with the glass curtain wall. It is not only a sense of non-compliance with the glass curtain wall, but also because of its fashion, beauty, modernity and technology, adding a special beauty to the urban architecture. Therefore, the transparent LED screen has won unanimous recognition in the market and has received extensive attention and enthusiasm.
Third, the characteristics of transparent LED display (1) high transparency effect has a very high perspective, with a permeability of 70% -85%, to ensure the lighting requirements between the floor, glass facade, windows and other lighting structures and The range of viewing angles ensures the original lighting perspective of the glass curtain wall.（2）It does not take up space and is light in weight. The thickness of the main board is only 10mm, and the display screen body generally weighs only 10Kg/m2. It does not need to change the building structure and is directly fixed to the glass curtain wall. (3) No need for steel frame structure, saving a lot of installation and maintenance costs. It is directly fixed to the glass curtain wall and does not require any steel frame structure, which saves a lot of cost. (4) Unique display effect Because the display background is transparent, the advertising picture can be suspended in the glass wall, which has good advertising effect and artistic effect. (5) Easy and quick maintenance indoor maintenance is fast and safe, saving manpower and material resources. (6) Energy saving and environmental protection does not require traditional refrigeration system and air conditioning to dissipate heat, which is more than 30% energy saving than ordinary LED display.
Fourth, five problems that need to be solved in transparent LED display (1) The choice of permeability and point spacing is from According to several products on the market, the transparent screen has a maximum penetration rate of 85% and a dot spacing of at least 3mm. For transparent screens, is it that the penetration rate and dot spacing have reached the limit? In fact, it is not because the PCB board, the driver IC, and the lamp bead itself are opaque. If the dot pitch is made smaller, it must be at the expense of losing part of the permeability, and the high-passivity is just transparent. The biggest advantage of the screen is that the increase in the penetration rate is the expansion of the dot pitch, which affects the clarity and display of the screen. Therefore, this is a dilemma. (2) After-sales service, product maintenance convenience and product reliability. First of all, the side-emitting LED lamp bead used in the transparent LED display on the market is not strong in generality, poor in consistency and stability, resulting in high production costs and troublesome after-sales service. Secondly, there are many customized products on the market, and the quantity is small. It is difficult to mass-produce, which is also an important reason for the high cost of LED transparent screen. Left picture: perspective effect when the screen is not bright; middle picture and right picture: effect when the screen is playing advertisements (3) How to achieve “true transparency” The so-called “true transparency” means that the transparent screen and the glass structure are Real integration. (4) Standardization and customization of the problem standardization can reduce costs, customization can make the transparent screen and the building achieve a high degree of harmony. (5) The problem of transparent transmission on the back of the transparent screen on this screen to play advertisements, in the design of advertising content screen At present, it is necessary to remove the unnecessary background color and replace it with black. Only the content to be expressed is displayed, and the black portion does not emit light during playback, which is a transparent effect. This playing method can greatly reduce light pollution.
Fifth, transparent LED display market application potential. The new transparent LED display has opened up a new application field and has broad market prospects. It is especially suitable for the field of “construction media”, which caters to the needs of an emerging market and successfully created A quality outdoor media resource. According to statistics, China’s modern glass curtain wall has a total area of more than 70 million square meters, mainly concentrated in urban areas. Such a huge glass curtain wall is a huge potential market for outdoor media advertising. The advertising value of this market is not yet available. It has been fully developed, and the glass curtain wall is a new blue ocean field in the case of urban outdoor advertising resources are increasingly exhausted. The scope of this field is very wide, such as urban landmark buildings, municipal buildings, airports, automotive 4S shops, hotels, banks, chain stores and other glass curtain wall buildings with commercial value.
