First, what is a transparent LED display?

    Transparent LED display as the name suggests is that LED electronic display has the property of passing through light like glass. Its realization principle is the micro-innovation of the light bar screen, the patch manufacturing process, lamp bead packaging, control system have been targeted improvements, coupled with the structure of the hollow design, reducing the obstruction of the line of sight of the structural components, and maximizing 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 like suspended above the glass curtain wall. LED transparent screen allows the application of LED display to expand to the two major markets of architectural glass curtain wall and commercial retail window, 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 70%-95% permeability, panel thickness is only 10mm, LED unit panel can be installed from behind the glass close to the glass, the unit size can be customized according to the glass size, the impact on the glass curtain wall lighting perspective is also very small, and easy to install and maintain.

Second, the background of the birth of the transparent LED display

    Along with the proliferation of outdoor advertising LED display is a series of negative problems, including the image of the city. LED display in the work can indeed play a role in lighting the city, release information function, but in the "rest" time is like a "scar" of the city, and the surrounding environment seems incompatible, greatly affecting the beauty of the city, 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 and more stringent.

    The transparent LED display not only integrates all the advantages of conventional outdoor HD LED displays, but also eliminates the problem of urban aesthetics to the maximum. 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 outdoor communication, it avoids the approval of outdoor advertising very well.

     In addition, with the acceleration of the pace of urban construction, glass curtain wall this high-end atmosphere on the grade of building materials has gradually become popular, transparent screen with its thin, no need for steel frame structure, easy installation and maintenance, good permeability and other characteristics, and glass curtain wall can be described as a hit, applied to the glass curtain wall not only has no sense of violation, but also because of its fashion, beauty, full of modern sense and scientific and technological atmosphere, to the city building has added a special sense of beauty. Therefore, the LED transparent screen has won everyone's unanimous recognition in the market and has been widely concerned and popular.

Third, the characteristics of transparent LED display

    (1) The high transparency effect has a very high perspective rate, with a permeability of 70%-95%, which ensures the lighting requirements and viewing angle range of the lighting structure between floors, glass facades, windows and other lighting structures, and ensures the original lighting perspective function of the glass curtain wall

    (2) Does not occupy space, light weight. The thickness of the motherboard is only 10mm, and the general weight of the display screen is only 12Kg/&#;, without changing the building structure, directly fixed on the glass curtain wall.

    (3) No steel frame structure is required, saving a lot of installation and maintenance costs. Fixed directly on the glass curtain wall, without any steel frame structure, saving a lot of costs.

    (4) The unique display effect because the display background is transparent, which can make the advertising screen give people the feeling of floating on the glass curtain wall, and has a good advertising effect and artistic effect.

    (5) Convenient and fast maintenance indoor maintenance, both fast and safe, saving manpower and material resources.

(6) Energy saving and environmental protection do not require traditional refrigeration system and air conditioning heat dissipation, which is more than 30% more energy-saving than ordinary LED display.

Fourth, transparent LED display needs to solve five problems

    (1) The choice of permeability and point spacing dilemma From the perspective of several products on the current market, the permeability of transparent screens has reached 85%, and the minimum point spacing is 3mm. For the transparent screen, is its permeability and point spacing reached its limit? In fact, it is not, because the PCB board, the driver IC, and the lamp beads themselves are opaque, if the point spacing is made smaller, it is bound to lose part of the permeability at the expense, and high permeability is just the biggest advantage of the transparent screen; The price of improving the permeability is the expansion of the point spacing, which affects the clarity and display of its picture. Therefore, it is a dilemma.

     (2) After-sales service, product maintenance convenience and product reliability. First of all, the versatility, consistency and stability of the side-emitting LED beads used in the transparent LED display on the market are not strong, resulting in high production costs and troubled after-sales service. Secondly, at present, there are more customized products on the market, the amount is small, and large-scale production is more difficult, which is also an important reason for the high cost of LED transparent screens.

    (3) How to achieve "real transparency" The so-called "real transparency" is that the transparent screen and the glass structure should be truly integrated.

  (4) Standardization and customization of the problem standardization can reduce costs, customization can make the transparent screen and the building to achieve a high degree of harmony.

(5) The problem of transparent screen back light transmission on this screen plays advertising, in the design of advertising content screen, the unnecessary background color is currently removed, replaced by black, only the content of the desired expression is displayed, and the black part does not emit light when playing, that is, the transparent effect, this playback method can greatly reduce light pollution.

As their popularity soars, it's essential to understand the mechanisms behind their function and the implications of their use in our daily lives.

Introduction

Imagine a display that looks like a piece of glass when turned off but comes alive with vibrant images when activated. This is the magic of transparent LED screens, an innovation that is redefining the boundaries between digital displays and clear surfaces. As their popularity soars, it's essential to understand the mechanisms behind their function and the implications of their use in our daily lives.

The Concept of Transparency in LED Technology

Traditional LED screens, with their opaque back panels, were once the pinnacle of display technology. However, the quest for more immersive and integrated displays led to the birth of transparent LED technology. Advancements in materials and diode miniaturization now allow these screens to be nearly invisible when not in use, offering a window into both the digital and the physical world.

Core Technology of Transparent LED Screens

Transparent LED screens are marvels of engineering, composed of LEDs embedded in a clear substrate, usually glass or acrylic. These LEDs are spaced out to create transparency, allowing light to pass through when they're not lit. The mechanics of light transmission are finely tuned to ensure that when the LEDs are active, they produce bright, crisp images that seem to float in mid-air.

Manufacturing Transparent LED Screens

Creating these screens involves precise manufacturing processes where the balance between transparency and display functionality is paramount. Substrate materials must be carefully selected and treated, and LEDs are embedded without the traditional opaque backing. Uniformity and clarity are critical, and achieving these at scale poses significant manufacturing challenges.
