How to calculate the number of receiving cards and sending cards for indoor and outdoor LED displays?

一. Calculation method of indoor full-color LED display sending card and receiving card:

For example:

Now the customer has customized a P2.5 indoor full-color display screen, which requires a width of 5 meters and a height of 2 meters.

1. Calculate the quantity of the LED modules:

The unit board size of the P2.5 display is: 32cm*16cm.

Number of modules used in width: 500cm/32cm=15.6, calculated based on 15 pieces.

The height of the module used is 200cm/16cm=12.5, calculated based on 12 pieces.

(The number of modules is generally calculated based on the small principle. If the large principle is used, it is very likely that it will not be installed. It depends on the specific situation and cannot be generalized)

2. Calculate the resolution of length and width:

(The pixels of the P2.5 indoor unit board are: 128*64)

The actual resolution of the LED display is:

width: 128×15=1920, height: 64×12=768

3. Calculate the quantity of receiving card:

(The receiving card of the indoor screen has a loading width of 128 points, and the height is generally not limited. You can carry as many screens as there are interfaces. However, some manufacturers have restrictions on the loading height of the receiving card. For example, Nova, the 12-port receiving card can basically carry P2 and below. It cannot be fully loaded, please pay attention to the loading parameters when purchasing)

Width: 1920÷128=15,

Height: 12 pieces, just choose a receiving card with 12 or 16 HUB75 interfaces. If it is a receiving card with 8 HUB75 interfaces, you need two rows, that is, 24 pieces.

4. Calculate the quantity of sending cards (two-in-one video processor)

(The sending card generally controls 1.31 million points, and does not exceed the load. The two-in-one video processor generally controls the load within 650,000 points per network port)

1920*768=1474560 points, approximately equal to 1.48 million points

If it is a sending card solution, you need 2 sending cards. If you use a two-in-one video processor, you need a 4-port video processor (the two-in-one video processor can carry 650,000 points per network port. Each manufacturer may have some Difference, pay attention to the loading parameters when purchasing)

二. Calculation method of outdoor full-color LED display sending card and receiving card:

For outdoor full-color LED displays, we can calculate it based on the number of boxes, usually one box per card.

For example: The customer customized a P10 outdoor full-color display screen with a required width of 20 meters and a height of 12 meters.

The P10 cabinet with a size of 96cm*96cm is selected. It can be concluded that:

Quantity of cabinets required for width: 20÷0.96=20.8, calculated as 20

Quantity of cabinets required for height: 20÷0.96=20.8, calculated as 20

1. Calculate the quantity of receiving card:

Number of led cabinets: 20×12=240

One cabinet per card, 240 receiving cards required

2. Calculate the resolution

According to the above calculation method, taking integers, the width is 20 boxes and the height is 12 boxes.

The actual resolution of the display is:

Width: 20×96=1920 Height: 12×96=1152

3. Calculate the number of sending cards (two-in-one video processor)

(one sending card generally controls 1.31 million points, which does not exceed the load. A network port of a two-in-one video processor generally controls 650,000 points)

1920*1152=2211840 points, which is approximately equal to 2.22 million points

If it is a solution of sending card, you need 2 sending cards. If you use a two-in-one video processor, you need a 4-port video processor (the two-in-one video processor can carry 650,000 points per network port. Each manufacturer may have some Difference, pay attention to the loading parameters when purchasing)

Summary: Generally speaking, the receiving card is calculated based on the resolution of the display screen indoors, and the number of boxes (one card in one box or one card in two boxes) outdoors. As for the sending card or two-in-one video processor, both indoor and outdoor calculations are based on the screen resolution.
