Curved LED display how to spell a good effect
An arc-shaped building needs to be installed with an LED display. Whether the specification and model modules in the design plan can assemble a perfect arc-shaped effect is related to the radius of the arc of the building, and also has a direct relationship with the shape of the bottom shell of the module.
The LED display screen can be used as a curved screen or a circular screen because the bottom shell of the module kit has a draft angle!
If the module specifications and draft angles are known, and the modules are bent at the maximum angle, the radius of the arc formed by the modules can be calculated with the help of CAD.
The following are the most common LED display module specifications on the market and common bottom shell draft angles (1, 1.5, 2, 3 degrees) and the minimum radius of the arc they can form:
Therefore, if you want to evaluate whether a circular arc building can be used as a curved screen, you need to first understand the draft angle of the bottom shell of the LED display module from the manufacturer, and calculate the radius of the arc building, and then compare it with the data in the table. In comparison, as long as the arc radius is greater than the minimum radius, a perfect arc screen or ring screen can be assembled, and if it is smaller than the minimum radius, there will be gaps.
The radius of an arc can be calculated like this:
1. First pull the wire to measure the chord length b of the arc;
2. Then measure the vertical distance a (chord height) from the center point of the chord to the top of the arc;
3. It can be obtained from the Pythagorean theorem: R2=(R-a)2+(b/2)2; under conversion, that is:
4. After calculating the radius R, compare it with the data in the above table, if the radius is larger than the minimum radius in the table, it is suitable for arc screen or ring screen.
