LED full color screen points how to calculate?In fact, in order to solve this problem, LED display manufacturers have summarized a practical method for calculating the points of indoor display screen to share with you:

We know that to know the number of points of a display screen, we must know the screen area and model information of LED full-color display screen before we can specifically calculate the number of points of indoor LED display screen.

First, let‘s popularize the concept of point spacing. P stands for the abbreviation of point in English, representing the distance between the center point and the center point, which is commonly referred to as the point spacing (the default unit of point spacing is mm).So you get the idea, indoor screen P3 point spacing is 3mm, indoor screen P4 point spacing is 4mm, and so on.

For example, the P4 indoor display screen has a point spacing of 4mm and a square meter area of 62500 points. The calculation and analysis 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, H=1000mm/4mm=250 points in width. Since all points are arranged in a regular matrix, L*H=(1000mm/4mm)*(1000mm/4mm)=(1000mm/4mm)2=62500 points in the area of 1 square meter.

For the convenience of understanding the calculation method of indoor LED screen points, here is an example: when the customer customizes P4 indoor full-color LED screen, 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:

I. estimation method:

L * H = (5000 mm / 4 mm) * (3000 mm / 4 mm) = (1000 mm / 4 mm) 2 = 937500 points.

Ii. Accurate methods:

It is assumed that 128mm x 64mm unit plates are used, and the number of unit plates is required:

Length 5000mm/128mm=39.06 blocks and approximately 39 blocks

Width 3000mm/64mm=46.875 pieces with 47 pieces

Actual screen length 39*128/1000=4.992 m

The actual screen width is 47*64/1000=3.008 meters

L * H = (4992 mm / 4 mm) * (3008 mm / 4 mm) = (1000 mm / 4 mm) 2 = 938496 points.

It can be seen that the calculation of the two methods is slightly different, which is because the actual screen body is not as required, and there will be a little error due to the limitation of the size specification of the unit board and box body.But the structure is reliable, the above is about indoor L display point calculation method, more questions can contact derensel, enthusiasm for your service.
