![]() ![]() The wind permeability factor, in general, is expressed as C f. Also, here, transparency is not the same as wind permeable. What you also can see is that the wind force has a significant grip on the scrim. You can still see the building behind it. The picture below clearly shows this temporary roof structure is cladded with transparent scrim or gauze. This same effect of under pressure or drag occurs for any item that is subject to wind force. The more aerodynamic the vehicle is, the lesser the drag. It clearly shows the "drag" or "under pressure" indicated in blue at the vehicle's back. The picture below shows a car in a wind tunnel. The wind that passes the screen causes drag and increases the wind forces on the screen, lowering the permeability factor. Wind permeability is a factor expressing the amount of wind that passes through an object.Ī transparent LED screen looks open, but the shape of components determines the aerodynamic behavior of the LED panel. Are you still skeptical? Just go outside, hold a piece of gauze cloth in the wind and see what happens. In this respect, a transparent LED screen should not be confused with wind permeability or "blow-through" LED. ![]() It's subject to wind loading or wind pressure. This also applies to temporary structures, such as roof structures or LED screens, as often used in the entertainment industry.Ī large LED wall will behave like a massive sail in the wind. Except for unforeseen conditions outside the design scope, these pre-conditions will make it unlikely that the structure will fail. This also applies to LED screen support structures.Ī guaranteed structurally sound structure needs to be designed, approved, build, inspected, checked, and maintained by a structural engineer or competent person. Let's explain.Īny structure is subject to possible failure when not built and used according to the guidelines and design parameters set in each product's structural report and manual. ![]() To cut things short, a transparent LED panel is not the same as a blow-through LED panel. A persistent misunderstanding is the existence of blow-through LED panels. The outdoor use of LED screens is still subject to myths and unawareness of possible risks. ![]()
