What is the LED display points and how to count

　　To know the number of points of an LED display, you must first know the screen area and model information of the full-color LED display before you can calculate the number of points about the LED display. The following full-color LED display manufacturers will tell you how the full-color LED display points are calculated.

　　First, let everyone popularize the concept of dot pitch of full-color LED display. P means the abbreviation of point in English. It represents the distance between the center point and the center point, which is often referred to as the point pitch. The default unit of the point pitch is mm. . The dot pitch of the indoor LED display P3 is 3mm, the dot pitch of the indoor LED display P2 is 2mm, and so on.

　　For example, indoor LED display P4, the dot pitch is 4mm, and the number of P4 dots per square meter is 62500. 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 in the length: L=1000mm/4mm=250 points, the same way, there are H=1000mm/4mm=250 points in the width, because all points They are all arranged in a regular matrix, so in an area of 1 square meter, there will be L*H=(1000mm/4mm)*(1000mm/4mm)=250*250=62500 points.

　　In order to give everyone a deeper understanding of the calculation method of full-color LED display points, here is a customer-customized P4 full-color LED display as an example. The required size is 5 meters in length, 3 meters in width, and a total area of 15 square meters. Then there are two A calculation method for reference:

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

　　2. Precise method: Assuming a 128mm x 64mm unit board is used, the number of unit boards required is 5000mm/128mm=39.06 pieces ≈ 39 pieces wide, 3000mm/64mm=46.875 pieces ≈ 47 pieces; the actual screen body length It is 39*128/1000=4.992 meters, and the actual screen width is 47*64/1000=3.008 meters. The actual number of points of the entire LED display is L*H=(4992mm/4mm)*(3008mm/4mm)=938496 points.

　　It can be seen that there is a slight difference between the two methods of calculation. This is because the full-color LED display is not made according to conventional requirements, and is limited by the unit board and box size specifications. It is normal for a little error to occur. The above is the summary of full-color LED display manufacturers on the calculation method of LED display points, I hope to help everyone.
