How is the transparency rate of LED transparent screens calculated?

To calculate transparency, we first need to understand the definition of transparency. Transparency is a physics term that indicates the high efficiency of light passing through a display system, etc. The transparency of a transparent screen is defined as the percentage of the total lumen value between the specific lumen value of the LED transparent screen that has passed through it. A very simple calculation method is: Transparency=(Transparent indoor space/Light bar spacing) * 100%

There is currently no national standard for calculating the transparency rate of transparent screens in the field of LED transparent displays. Therefore, LED transparent screen manufacturers have different calculation methods for the "transparency rate" or "translucency" of their products. The key logic is as follows:

The transparency rate usually only measures a part of the behavior of the light strip and LED light strip, that is, the shading of the switch power box is not included, and the shading of the outer frame of the housing is not included, PC、 The shading of acrylic panels or laminated glass (single-sided or even two-layer) is not included.

Taking the P3.91 transparent screen as an example, it is known that the thickness of the light strip PCB is 2mm, and the distance between the light strips is 3.91mm. Therefore, its transparency in indoor space is 1.91mm, and the transparency is 1.91/3.91 * 100%

Therefore, the "transparency rate" in the performance parameters of LED transparent screen products nowadays is the result of diverse and different calculation methods. Customers should carefully feel the transparency rate of the transparent screen when choosing LED transparent screen products, taking into account gender factors.
