The use of buildings as a carrier for information dissemination is often referred to as “construction media.” With the development of LED and other optoelectronic technologies, construction media technology has also made rapid progress, and has been sought after by the market in recent years, especially in the construction of glass curtain walls. Application, there are various solutions. A new type of high-transparency LED display technology, featuring high transparency and ultra-lightweight, has obvious technical advantages in the field of construction media.
First, what is a transparent LED display?
Transparent LED display As the name implies, the LED display has the property of transmitting light like glass. Its realization principle is the micro-innovation of the light bar screen, and the targeted improvement of the chip manufacturing process, the lamp bead package, and the control system, together with the hollow design structure, reduces the obstruction of the structural components to the line of sight. Maximize the perspective effect.
At the same time, it also has a novel and unique display effect. The audience stands at an ideal distance and the picture is suspended above the glass wall. LED transparent screens allow the application of LED display screens to expand into the two major markets of architectural glass curtain walls and commercial retail windows, becoming a new trend for the development of new media.
Transparent LED display is a new type of ultra-transparent LED display technology, it has a 70% -95% transparent rate, the panel thickness is only 10mm, LED unit panel can be installed from the glass behind the glass to install, the unit size can be According to the glass size customization, the influence on the glazing of the glass curtain wall is also very small, and it is convenient for installation and maintenance.
Second, the background of the birth of transparent LED display
With the proliferation of outdoor advertising LED display is a series of negative issues, including the image of the city. When the LED display is working, it can really illuminate 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. , destroyed the city's landscape.
Due to the appearance of these problems, the approval of outdoor large-screen installations has become more and more cumbersome, and the management of outdoor advertising has become increasingly strict.
The transparent LED display not only integrates all the advantages of a conventional outdoor HD LED display, but also eliminates the aesthetic problems of the city. Because it is mostly installed behind a glass curtain wall, it does not have any influence on the surrounding environment even if it does not work during the day. At the same time, because it adopts a new form of outdoor advertising for indoor advertising, it circumvents the approval of outdoor advertising.
In addition, with the accelerating pace of urban construction, high-grade glass building materials of the high-end atmosphere have gradually become popular. The transparent screen is characterized by its thinness, no steel frame structure, simple installation and maintenance, and good permeability properties. And glass curtain wall can be said to hit it off, not only does not violate the glass curtain wall, but also because of its stylish, beautiful, modern and technological atmosphere, to the city building has added a special beauty. Therefore, LED transparent screen has won everyone's unanimous approval in the market, and has received extensive attention and blitz.
Third, the characteristics of transparent LED display
(1) The high transparency effect has a very high perspective, with a 70% - 95% transparency rate, ensuring the lighting requirements and viewing angle range of the lighting structure between floors, glass facades, windows, etc., ensuring the original glass curtain wall Some lighting perspective function.
(2) does not take up space, light weight. The thickness of the main board is only 10mm, and the display screen body generally weighs only 12Kg/m2. It does not need to change the building structure and is directly fixed on the glass curtain wall.
(3) No steel frame structure is required, which saves a lot of installation and maintenance costs. Directly fixed to the glass curtain wall, without any steel frame structure, saving a lot of costs.
(4) Unique display effect Because the display background is transparent, the advertising screen can give people the feeling of being suspended on the glass curtain wall, and has a very good advertising effect and artistic effect.
(5) Convenient and convenient maintenance Indoor maintenance is quick and safe, saving manpower and material resources.
(6) Energy-saving and environmental protection does not require the traditional refrigeration system and air-conditioning to dissipate heat, which is more than 30% energy-saving than ordinary LED display.
Fourth, the five issues that transparent LED display needs to solve
(1) Choice of dilemma between permeation rate and point spacing From the perspective of several products currently on the market, the transparent screen has the highest transparency rate of 85% and the smallest point spacing is 3mm. In terms of transparent screens, isn't its transparency and dot spacing already reached the limit? In fact, it is not because the PCB board, driver IC, and lamp beads are not transparent. If the dot pitch is made smaller, it must be at the expense of losing some of the permeability, and the high transparency rate is just transparent. The biggest advantage of the screen lies in; the cost of improving the transparency rate is the expansion of the point spacing, which affects the clarity and display effect of its screen. Therefore, this is a dilemma.
(2) After-sales service, product maintenance convenience and product reliability or not. First, the versatility, consistency, and stability of the side-emitting LED lamp beads used in the transparent LED display on the market are poor, leading to high production costs and troublesome after-sales services. Secondly, there are many products that are customized on the market at present, and the mass production is difficult. This is also an important reason for the high cost of LED transparent screens.

(3) How to achieve "true transparency" The so-called "true transparency" is the true integration of transparent screens and glass structures.
(4) Standardization and customization problems Standardization can reduce costs, and customization can make the transparent screen and the building reach a high degree of harmony.
(5) Translucent light on the back of the transparent screen. When the advertisement is displayed on this screen, when designing the advertisement content screen, the unnecessary background color must be removed, replaced with black, and only the desired expression content is displayed and played. When the black part is not light, it is a transparent effect. This method of play can greatly reduce light pollution.
V. Transparent LED display market application potential
Xiao Bian believes that the new transparent LED display has opened up a new application field and has broad market prospects. It is particularly applicable to the “architecture media” field, caters to the needs of a new emerging market, and has successfully created a quality outdoor environment. media resources. According to statistics, the total area of modern glass curtain walls in China has exceeded 70 million square meters, mainly concentrated in urban areas. The huge amount of glass curtain walls is a huge potential market for outdoor media advertising. The advertising value of this market is still not Being completely developed, the glass curtain wall is a new blue ocean area under the condition that the city's outdoor advertising resources are depleted. The scope of this area is very wide, such as the city's landmark buildings, municipal buildings, airports, auto 4S shops, hotels, banks, chain stores and other commercial glass curtain wall buildings.
