The number of receiving cards on the ASRAM full-color LED display, that is to say, calculate the maximum loading capacity of each receiving card. Specifically, the loading capacity of each receiving card is different, and different receiving cards have full-color LEDs. The length and width of the display screen are different (the length and width refer to pixels), which is obtained according to the design of the receiving card. For example, Nova's control system, the control range of each receiving card: 256*256 points (DH7508 card), the pixels of the receiving card must be larger than the pixels of the screen, so that it can be brought up.
For example: Now the customer has customized a P10 indoor full-color display screen, which requires a length of 10 meters and a height of 5 meters.
1. Calculate how many modules are used.
The unit board size of the P10 display is: 32cm*16cm.
Number of modules used for length: 1000cm/32cm=31.25
Width using module 500cm/16cm=31.25
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: 32×32=1024 Width: 16×32=512
3. Calculate the number of receiving cards.
(receiving card of indoor screen 256*256)
Length: 1024÷256=4
Width: 512÷256=2
4×2+1=9 receiving cards (one extra receiving card)
We can also calculate according to the number of boxes, one or two boxes and one receiving card, one card for one box or two boxes for one card, and one card for one box for government projects
