The most important thing about the P3.91 LED transparent screen is its light transmittance. The higher the light transmittance, the better the quality of the LED transparent screen. Therefore, customers often ask how much its transmittance and light transmittance are calculated. Woolen cloth?
Calculation method of LED transparent display
To calculate permeability, we must first understand its concept. Transmittance is a physical word, which indicates the efficiency of the light transmitted by the display device. The transmittance of a transparent screen is defined as the percentage of the luminous flux that the screen actually passes through to the total luminous flux that passes through. The basic calculation formula is: Transparency Rate = (light transmission space / light bar interval) * 100%

However, there is no fixed standard for the calculation of the transparency of transparent screens in the transparent display industry for the time being, so LED transparent screen manufacturers have different calculation methods for the “transparency” or “transmittance” of their own products.
The transmittance is often only calculated for the main part of the light bar and the light board, that is, the shading of the power box is not included, the shading of the box frame is not included, and the shading of PC, acrylic plate or glass (single-layer or even double-layer) is not included. counted.
Taking the P12 transparent screen as an example, when the thickness of the light bar PCB is 2m, and the distance between the light bar and the light bar is 12mm, the light transmission space is equal to 10mm, so the light transmittance=10/12*100%=83.3%
For customers who have never been in contact with LED transparent screens and have never seen the real thing, “transparent screen” is a very emotional and sci-fi vocabulary. Therefore, every time a transparent screen is mentioned, high-tech pictures in film and television works and concept product promotional films will appear in many people\’s minds.
However, LED transparent screens have nothing to do with these. Most of the high-tech pictures in the movie are virtual technology, which reflects a future technology and a direction of future development of transparent display.

To learn the calculation method of transmittance, let\’s take a look at the installation methods of LED transparent screens. After all, transparent LED displays are different from other LED displays and have a lighter structure. So, what are the installation methods of transparent screens?
Because of the particularity of the structure of the LED transparent screen, it is not composed of LED modules, but composed of countless light strips, so the installation method of the led transparent screen is destined to be the same as other LED display installation methods. Not the same. Next, let’s take a look at how to install the led transparent screen? What are the installation methods?
In different installation environments, the installation methods of led transparent screens are also different. The common installation methods of transparent screens include hoisting, fixed installation, base installation, etc. The most common one is hoisting for stage dance, exhibition halls and other fields.
Floor base
There are many common in glass windows, exhibition halls, etc. For example, the height of the screen body is not high, and it can be simply fixed at the bottom. If the height of the screen body is high, it needs to be fixed up and down behind the screen body to realize the fixation of the screen body.

Frame installation
Composite bolts are used to directly fix the box frame on the glass curtain wall keel without any steel structure, and it is mainly used in the field of architectural glass curtain walls.
Ceiling mount
It is mainly used for indoor strip screens and frame structure screens, and can be used for hoisting. This installation method must have a suitable installation location, such as where there is a beam lintel above. Standard hangers can be used for the indoor concrete roof, and the length of the hangers is determined according to the site conditions. The indoor beams are hoisted by steel wire ropes, and the outdoor and the screen are decorated with steel pipes in the same color.
Suspended installation
Wall-mounted installation can be used indoors, requiring concrete beams on the solid wall or at the suspension. Outdoor installation mainly relies on steel structure, and there is no limit to the display area and weight.
The above four are the common installation methods of LED transparent screen. According to different application scenarios, the type of transparent display screen selected will be different. Even if the installation method is different, it will be flexibly changed according to the actual situation of the site and the design requirements. No matter which installation method is used, the steel structure used in the LED transparent screen is very small, and it only needs to be carried out on the installation point or installation surface.
