BOC teaches you how to calculate LED transparent screen permeability

LED transparent screen, "transparent" is its biggest feature. Someone will often ask, LED transparent screen is completely transparent? What is its permeability and transmittance?

"Transparent screen" is definitely a word with enough sense and full of science fiction color for customers who have not seen real led transparent screen and contacted LED transparent screen. When it comes to transparent screens, many people probably picture high-tech images from movies and concept product promos.
However, the LED transparent screen has nothing to do with these. Most of the high-tech pictures in the movie are virtual technologies, reflecting a kind of future technology and a direction of transparent display in the future.
So, how to calculate the permeability of LED transparent screen?
To calculate permeability, we must first understand the concept of permeability. Permeability is a physical term that indicates the efficiency of light transmission of display equipment, etc. The permeability of transparent screen is defined as the percentage of the actual luminous flux through the screen body and the total luminous flux through. The simplest calculation formula is: permeability = (transparent space/lamp bar interval) * 100%
For the calculation of transparent screen permeability, there is no industry standard for LED transparent display industry, so LED transparent screen manufacturers have different calculation methods for their products "permeability" or "transmittance", the main logic is as follows:
Connect the main body part that rate often calculates lamp strip, lamp board only, namely the shading of power supply box does not plan, the shading of box frame does not plan, PC, acrylic board or glass (single layer even double layer) shading also does not plan.
Take the transparent screen of P12 as an example. Given that the PCB thickness of the indicator strip is 2m and the distance between the indicator strip and the indicator strip is 12mm, the light transmittance is 10mm, so the light transmittance is 10/12 * 100%
Therefore, now LED transparent screen company product technical parameters
