How can curved LED display spell a good effect

LED display can do arc screen or circular screen, because the bottom shell of the module kit has a pull die slope!

If you know the module specification, the drawing Angle, and the maximum Angle between the modules, then the radius of the final arc of the module can be calculated with the help of CAD.

If you want to evaluate a circular arc screen, the building can do need to know first to manufacturer LED display module sump draft Angle, and calculate the radius of the circular building, with the data in the table again, as long as it is greater than the minimum radius of circular arc radius can be assembled a perfect arc screen or circular screen, there is crack is less than the minimum radius.

The radius of an arc can be calculated as follows:

1. As shown in the figure above, first pull the wire to measure the chord length B of the arc;

2. Then measure the vertical distance a (chord height) between the center point of the string line and the top of the arc line;

3, from the Pythagorean theorem can be obtained: R2= (r-a) 2+ (b/2) 2; Under the conversion, namely:

4. After calculating the radius R, compare 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 annular screen.
