To know the number of LED display points, you must first know the full-color LED display screen area and model information in order to specifically calculate the number of points on the LED display. The following full-color LED display manufacturers to tell you how to calculate the full-color LED display points.
First of all, for everyone to popularize the point spacing concept of full-color LED display, P means the English point abbreviation, representing the distance between the center point and the center point, which is often called the point spacing, the default unit of the dot pitch is mm . The indoor LED display P3 has a dot pitch of 3 mm, the indoor LED display P2 has a dot pitch of 2 mm, and so on.
For example, the indoor LED display P4, the distance between the dots is 4mm, and the area of ​​one square meter of P4 is 62500. The calculation method is as follows:
1 square meter is the area of ​​1000mm in length and 1000mm in width, so there can be so many points in length: L=1000mm/4mm=250 points. Similarly, there are also H=1000mm/4mm=250 points in width, due to all the points. All are regular matrix arrays, so on 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 more profound understanding of the full-color LED display point calculation methods, here to customize the P4 full-color LED display as an example, the required size is 5 meters long, 3 meters wide, a total area of ​​15 square meters, then there are two The calculation method is for reference:
First, the estimated method:
L*H=(5000mm/4mm)*(3000mm/4mm)=937500 points.
Second, the precise method:
It is assumed that a 128mm x 64mm specification cell board is used. The number of cell plates required is 5000mm/128mm=39.06 pieces, 39 pieces, and 3000mm/64mm=46.875 pieces are 47 pieces; the actual screen length is 39*128/1000. =4.992 meters, 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 the two methods have slightly different calculations. This is because the full-color LED display screen is not made according to the conventional requirements. It is limited by the size specifications of the cell board and the box. It is normal that there is a slight error. The above is a summary of the calculation methods for LED display points by full-color LED display manufacturers. We hope to help everyone.
