A new type of highly transparent LED display technology, which is highly transparent, ultra-light and thin, and has obvious technical advantages in the field of architectural media.
1. What is a transparent LED display?
Transparent LED display, as the name suggests, means that the LED display has the property of transmitting light like glass. Its implementation principle is a micro-innovation of the light bar screen. Targeted improvements have been made to the patch manufacturing process, lamp bead packaging, and control system. In addition, the hollow design structure reduces the obstruction of the line of sight by structural components and maximizes the perspective effect.
At the same time, it also has a novel and unique display effect. When the audience stands at an ideal distance to watch, the picture seems to be suspended on the glass curtain wall. LED transparent screens have expanded the application territory of LED displays to the two major markets of architectural glass curtain walls and commercial retail windows, becoming 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 permeability of 70%-95% and a panel thickness of only 10mm. The LED unit panel can be installed close to the glass from behind the glass. The unit size can be customized according to the glass size. It has little impact on the lighting perspective of the glass curtain wall and is easy to install and maintain.
2. The background of the birth of transparent LED displays
With the proliferation of outdoor advertising LED displays comes a series of negative problems, including city image problems. The LED display screen can indeed brighten the city and release information when it is working, but when it is "resting", it is like a "scar" in the city, which is incompatible with the surrounding environment, greatly affecting the beauty of the city and destroying the city's scenery.
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 stringent.
The transparent LED display not only integrates all the advantages of conventional outdoor high-definition LED displays, but also eliminates urban aesthetic problems to the greatest extent. Because it is mostly installed behind a glass curtain wall, it will not have any impact on 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 and outdoor communication, it can well circumvent the approval of outdoor advertising.
In addition, as the pace of urban construction accelerates, high-end and high-end building materials such as glass curtain walls have gradually become popular. Transparent screens, with their thinness, no steel frame structure, easy installation and maintenance, and good transparency, are in perfect harmony with glass curtain walls. Not only does it have no sense of violation when applied to glass curtain walls, but also because it is fashionable, beautiful, modern and technological, it adds a special sense of beauty to urban buildings. Therefore, LED transparent screens have won unanimous recognition in the market and have received widespread attention and popularity.
3. Characteristics of transparent LED display
(1) The high transparency effect has extremely high perspective, with a transmittance of 70%-95%, ensuring the lighting requirements and viewing angle range of lighting structures such as floors, glass facades, windows, etc., and ensuring the original lighting and perspective function of the glass curtain wall.
(2) Does not take up space and is light weight. The thickness of the main board is only 10mm, and the general weight of the display screen body is only 12Kg/㎡. There is no need to change the building structure and it is directly fixed on the glass curtain wall.
(3) No steel frame structure is required, saving a lot of installation and maintenance costs. Directly fixed on the glass curtain wall without any steel frame structure, saving a lot of costs.
(4) Unique display effect Because the display background is transparent, it can make the advertising screen feel like it is suspended on the glass curtain wall, which has a good advertising effect and artistic effect.
(5) Maintenance is convenient and fast. 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 for heat dissipation, and it saves more than 30% energy than ordinary LED displays.
4. Five problems that need to be solved for transparent LED displays
(1) The dilemma of transparency and dot spacing. Judging from several products currently on the market, the transparency rate of transparent screens has reached a maximum of 85%, and the minimum dot spacing is 3mm. For a transparent screen, has its permeability and dot spacing reached its limit? In fact, it is not, because the PCB board, driver IC, and lamp beads themselves are opaque. If the dot spacing is made smaller, it must be at the expense of losing part of the permeability, and high permeability is exactly the biggest advantage of the transparent screen; and the price of increasing the permeability is the expansion of the dot spacing, which affects the clarity of the picture and the display effect. So it's a dilemma.
(2) After-sales service, product maintenance convenience and product reliability. First of all, the side-emitting LED lamp beads used in transparent LED displays on the market are not very versatile, consistent and stable, resulting in high production costs and troublesome after-sales service. Secondly, there are currently many customized products on the market in small quantities, making mass production difficult. This is also an important reason for the high cost of LED transparent screens.

(3) How to achieve "real transparency" The so-called "real transparency" means that the transparent screen must be truly integrated with the glass structure.
(4) Problems with standardization and customization Standardization can reduce costs, and customization can achieve a high degree of harmony between transparent screens and buildings.
(5) The problem of light transmission on the back of the transparent screen. When advertising on this kind of screen, when designing the advertising content screen, it is currently necessary to remove the unnecessary background color and replace it with black. Only the content that needs to be expressed is displayed. The black part does not emit light during playback, which is a transparent effect. This playback method can greatly reduce light pollution.
5. 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. It is especially suitable for the field of "architectural media", caters to the needs of an emerging market, and has successfully created a high-quality outdoor media resource. According to statistics, the total area of modern glass curtain walls in China has exceeded 70 million square meters, mainly concentrated 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 has not yet been fully developed. With urban outdoor advertising resources increasingly depleted, glass curtain walls are a new blue ocean field. The scope of this field is very wide, such as urban landmark buildings, municipal buildings, airports, car 4S stores, hotels, banks, chain stores and other glass curtain wall buildings with advertising and commercial value.
