On the basis of the conventional LED transparent screen, the light board is hollowed out to achieve a certain permeability, which is called led grille screen, and then in the LED grille screen technology, further optimization, the formation of today's LED transparent screen.
Why can transparent screens be transparent? What is the principle of it
The led transparent screen light board is one by one, with a hollow in the middle, reducing the structure's obstruction of people's vision, you can see the scene behind the display. From a distance, you can't even see the structure of the light bar, and it feels like the picture is suspended on glass.

Two practices within the LED transparent screen industry
1. For the traditional LED display, the module adds a hollow design, and then matches the new patch, drive circuit, control system, and realizes the optimization and innovation of the LED transparent display. Such products are represented by LED transparent screens/LED foil screens. It is mainly used in small and medium-sized areas, and has high requirements for display pixels. Common applications: glass curtain wall, commercial window, exhibition, auto show and other fields
2. Directly through the light bar splicing / lamp point, with a special structure and signal processing methods. Like the LED light bar screen and LED grid screen commonly used on the market, this method is usually used. Mainly suitable for large-area lighting display projects, usually the spacing is more than 20mm, because the clarity requirements of this type of screen are not high, suitable for long-distance large-area viewing. Common applications include: city light shows, large landmark displays, etc.
Grid screen skeleton structure
At present, the minimum spacing in the industry can be about 2.6mm, and the side light emitting LED transparent screen has also been introduced to the market, and the side area of the light bar that blocks the line of sight is less, so that the permeability rate is higher. UnitedMan Optoelectronics has also launched its own LED foil screen / LED photoelectric glass products, such products on the basis of LED transparent screen, the use of a new circuit and lamp bead mode, the permeability rate is greatly improved.
