How to calculate the number of receiving cards and sending cards for LED full-color display? In fact, this is related to the size and model of the led screen, so let's take a look at what is going on.



The number of receiving cards for the full-color LED display, that is to say, the maximum loading capacity of each receiving card is calculated. The specific loading capacity of each receiving card is different. The length and width of the color LED display screen are different (length and width refer to pixels), which is derived from the design of the receiving card. For example, the control system of Lingxingyu, the control range of each receiving card: 256*128 points, 256*64 points (RV901 card), full-color LED display scanning mode is calculated according to 256*128 points, outdoor full-color LED The static display screen can be calculated as 256*64 points, and the pixels of the receiving card must be larger than the pixels of the screen, so that it can be brought up.



1. The calculation method of indoor full-color LED display sending card and receiving card:

Example: Now the customer has customized a P10 indoor full-color display with a length of 20 meters and a height of 10 meters.

1. Calculate how many modules are used.

The unit board size of P10 display screen is: 32cm*16cm.

Number of modules used in length: 2000cm/32cmu003d62.5

Width use module 1000cm/16cmu003d62.5

2. Calculate the resolution of length and width:

(The pixel of P10 indoor unit board is: 32*16)

The actual resolution of the display screen is: Length: 32×63u003d2016 Width: 16×63u003d1008



3. Calculate the number of receiving cards.

(Indoor screen receiving card 256*128)

Length: 2016÷256u003d7.875, approximately equal to 8

Width: 1008÷128u003d7.875, approximately equal to 8

8×8+1u003d65 receiving cards (one more receiving card)



4. Calculate the number of sending cards

(Lingxingyu’s sending card is 1280*1024)

2016÷1280u003d1.575, which is approximately equal to 2

1008÷1024u003d0.98 is approximately equal to 1

1×2u003d2 sending cards.



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

For outdoor full-color LED displays, we can calculate according to the number of boxes, one or two boxes can receive one card, one box one card or two boxes one card.

1. Calculate the number of receiving cards.

Number of boxes: 21×13+1u003d274 pieces

Government projects: 273 receiving cards

General engineering: 273÷2+1u003d138 receiving cards

Note: All of the above need to prepare an extra receiving card

1. Calculation resolution:

According to the above calculation method, take an integer, 21 boxes in length and 13 boxes in width.

The actual resolution of the display screen is:


Length: 21×960u003d2016 Width: 13×960u003d1248



2. Calculate the number of sending cards




Summary: Generally, when receiving cards, indoors are calculated based on the display resolution, and outdoors are calculated based on the number of boxes (one box for one card or two boxes for one card). As for the sending card indoor and outdoor, it is calculated according to the screen resolution. If the above calculations are incorrect or there are misunderstandings, please contact us for corrections.
