Taking buildings as the carrier of information dissemination is usually called “building media”. With the development of optoelectronic technologies such as LED, building media technology has also made great progress, and has gradually been sought after by the market in recent years, especially in the application of glass curtain wall buildings. , various solutions appear. A new type of high-transparency LED display technology, featuring high transparency and ultra-thinness, has obvious technical advantages in the field of architectural media.
What is a transparent LED display?
The transparent LED display, as the name suggests, is that the LED display has the property of passing light like glass. Its realization principle is the micro-innovation of the light bar screen, and targeted improvements have been made to the patch manufacturing process, lamp bead packaging, and control system, and the hollow design structure reduces the blocking of the sight by the structural components. , to maximize the perspective effect.
At the same time, it also has a novel and unique display effect. The audience stands at an ideal distance to watch, and the picture is suspended on the glass curtain wall. The LED transparent screen has expanded the application territory of the LED display to the two major markets of architectural glass curtain walls and commercial retail windows, which has become a new trend in the development of new media.
Transparent LED display is a new type of ultra-transparent LED display technology. It has a transmittance of 70%-95%, and the panel thickness is only 10mm. The LED unit panel can be installed from the back of the glass against the glass, and the unit size can be Customized according to the size of the glass, the impact on the lighting and perspective of the glass curtain wall is also small, and it is easy to install and maintain.
The background of the birth of the transparent LED display
Along with the flood of outdoor advertising LED displays comes a series of negative problems, including the problem of city image. The LED display screen can indeed brighten the city and release information when it is working, but when it is “resting”, it seems to be a “scar” of the city, which is out of tune 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 installation has become more and more cumbersome, and the management of outdoor advertising has become more and more strict.
The transparent LED display not only integrates all the advantages of the conventional outdoor high-definition LED display but also eliminates the problem of urban aesthetics to the greatest extent. Because it is mostly installed behind the glass curtain wall, even when it is not working during the day, it will not have any impact on the surrounding environment. At the same time, because it adopts a new form of indoor advertising and outdoor communication, it avoids the approval of outdoor advertising.
In addition, with the acceleration of urban construction, glass curtain wall, a high-end and atmospheric building material, has gradually become popular. The transparent screen is light and thin, does not require a steel frame structure, is easy to install and maintain, and has good permeability. It can be said to be a hit with the glass curtain wall. The application of the glass curtain wall not only has no sense of incongruity but also adds a special beauty to urban buildings because of its fashion, beauty, modernity, and technology. Therefore, the LED transparent screen has won the unanimous approval of everyone in the market and has received extensive attention and enthusiasm.
The characteristics of a transparent LED display
The high transparency effect has a very high perspective rate, with a permeability of 70%-95%, which ensures the lighting requirements and viewing angles of lighting structures between floors, glass facades, windows, etc., and ensures the original glass curtain wall. Some lighting perspective functions.
It does not take up space and is light in weight. The thickness of the main board is only 10mm, and the general weight of the display screen is only 12Kg/㎡. It is directly fixed on the glass curtain wall without changing the building structure.
No steel frame structure is required, saving a lot of installation and maintenance costs. It is directly fixed on the glass curtain wall without any steel frame structure, which saves a lot of costs.
Unique display effect Because the display background is transparent, it can make the advertisement screen feel suspended on the glass curtain wall, and has a good advertising effect and artistic effect.
Maintenance is convenient and fast. Indoor maintenance is fast and safe, saving manpower and material resources.
Energy saving and environmental protection do not require traditional refrigeration systems and air conditioners to dissipate heat, which saves more than 30% more energy than ordinary LED displays.
Five problems that need to be solved in transparent LED display
The dilemma between transparency and dot pitch From the perspective of several products on the market, the highest transparency of transparent screens has reached 85%, and the minimum dot pitch is 3mm. For the transparent screen, has its permeability and dot spacing reached the limit? In fact, it is not, because the PCB board, the driver IC, and the lamp beads themselves are opaque. If the dot pitch is made smaller, it must be at the expense of losing a part of the permeability, and the high permeability is just transparent. The biggest advantage of the screen is; that the cost of improving the transparency is the expansion of the dot spacing, which affects the clarity and display effect of its screen. Therefore, it is a dilemma.
Questions about after-sales service, product maintenance convenience, and product reliability. First of all, the side-emitting LED lamp beads used in the transparent LED display on the market are not versatile, consistent, and stable, resulting in high production costs and troublesome after-sales service. Secondly, there are many customized products on the market, and the quantity is small, and it is difficult to mass-produce, which is also an important reason for the high cost of LED transparent screens.
How to achieve “true transparency” The so-called “true transparency” means that the transparent screen must be truly integrated with the glass structure.
Problems of standardization and customization Standardization can reduce costs, and customization can make transparent screens and buildings achieve a high degree of harmony.
The problem of light transmission on the back of the transparent screen When advertising is played on this screen when designing the content of the advertisement, the unnecessary background color should be removed and replaced with black, and only the content to be expressed should be displayed and played. When the black part does not emit light, it is a transparent effect. This playback method can greatly reduce light pollution.
Transparent LED display market application potential
The editor believes that the new transparent LED display has opened up a new application field and has broad market prospects, especially suitable for the field of “architectural media”, catering to the needs of an emerging market, and successfully creating high-quality outdoor media resources. According to statistics, the total area of modern glass curtain walls in China has exceeded 70 million square meters, mainly in urban areas. Such a huge stock of glass curtain walls is a huge potential market for outdoor media advertising. The advertising value of this market is not yet. Being fully developed, the glass curtain wall is a new blue ocean field under the situation that the urban outdoor advertising resources are increasingly depleted. The scope of this field is very wide, such as urban landmark buildings, municipal buildings, airports, automobile 4S stores, hotels, banks, chain stores, and other glass curtain wall buildings with advertising commercial value.
