To know the number of points of an LED display, you must know the area and model of full-color LED display before calculating the number of points of LED display.Below, full-color LED display manufacturer derunser (www.leddrse.com) will tell you how to calculate the number of full-color LED display Numbers.

First of all, popularize the point spacing concept of full-color LED display screen. P means the abbreviation of the English word point, which stands for the distance between the center point and the center point. Commonly known as point spacing, the default unit of point spacing is mm.The point spacing of indoor LED display P3 is 3mm, that of indoor LED display P2 is 2mm, and so on.

For example, the LED screen P4 in delunser room is 4mm apart and the number of P4 points per square meter is 62,500. The calculation method is as follows:

1 square meter is the area of 1000mm long and 1000mm wide, so there can be so many points on the length: L=1000mm/4mm=250. Similarly, H=1000mm/4mm=250 on the width. Since all points are arranged in a regular matrix, L*H=(1000mm/4mm)*(1000mm/4mm)=250*250=62500 on the area of 1 square meter.

In order to let everyone have a deeper understanding of the calculation method of the number of full-color LED display, take the P4 full-color LED display customized by the customer as an example, the size is required to be 5 meters long, 3 meters wide, and the total area is 15 square meters. Then there are two calculation methods for reference:

Method of estimation: L*H=(5000mm/4mm)*(3000mm/4mm)=937500 points.

2. Accurate methodThe actual length of the screen is 39*128/1000=4.992 meters, and the actual width of the screen is 47*64/1000=3.008 meters.The actual number of points for the entire LED display is L*H=(4992mm/4mm)*(3008mm/4mm)=938496.

It can be seen that the calculation of the two methods is slightly different. This is because the full-color LED display screen is not made according to the normal requirements, which is limited by the size and specification of the unit board and the box, and a little error is normal.Above is the full color LED display manufacturer derunsell about the LED display number calculation method summary, hoped can help everybody.
