Many people do not know how many receiving CARDS should be used on an LED display screen. Today, I have sorted out the calculation formula and size of receiving CARDS here. I hope it will be helpful for you.
I. calculation method of indoor receiving card:
Dimensions: P2.5:480*480 P3
Outdoor box size: P6:576*576 P4.81:250*250 P3.91:250*250 P8:960*960 (640*640) one card per box, 150/ card for receiving,
Power supply: a power supply with 10 board
Number of modules: length of the screen; length of the module; length of the screen; height of the module; height of the module; height of the module; height of the module; height of the module
Calculation method of indoor receiving card:
Example: indoor P10 is 20m long and 10m high
1
Calculate how many modules:
The unit board size of the P10 display screen is: 320mm x 160mm length; module number of use: 2000cm; 2.32cm =62.5 width; module number of use: 1,000cm; and 1.16cm =62.5
2
Calculate the resolution of length and width:
(P10 indoor unit plate pixel: 32 x 16)
The actual resolution of the display is: length: 32 x 63=2016 width: 16 x 63=1008
3
Calculating the number of receiving CARDS:
(indoor screen receiver card 256 x 128)
Length: 20162.256 =7.875, approximately equal to 8 width: 1008 2.128 =7.875, approximately equal to 8
8 times 8+1=65 receiving CARDS (one more card is needed)
4
Calculate the number of sending CARDS:
(the sending card of lingxing rain is 1280 x 1024)
Calculation formula of outdoor receiving card:
Example: outdoor P10 is 20m by 12m
The size of the P10 box is 960mm x 960mm, and it can be concluded that the length of the box needs to be 20
Number of receiving CARDS: number of boxes: 21 x 13+1=274 government projects: 273 receiving CARDS
General engineering: 273 2+1=138 receiving CARDS description: one more receiving card is required above
Ii. Calculation method of outdoor display screen:
01
The specific data (length, width and area) of the screen is given.
Example: the outdoor full color screen to make P20 is about 10 meters long and 6 meters wide
B. First of all, the specification (length and width of the box) of the unit box is 1280 * 960mm, and the resolution is 64 * 48. C.
Number of boxes for screen length or width = number of boxes for pre-made screen length or width
02
It only gives the area of the screen, not the width.
Example: if you make a P20 outdoor full color screen, the area is about 50 square meters.
B. if we only give the area, we have to calculate the length and width by ourselves.It can be calculated in proportion to length, width 4:3 or 16:9.It looks good.(here, for example, 4:3)
C. The theoretical screen length is: the square root of the length = (area 1.12) x 4 width = (area 2.12) x 3, that is, the length =8.16m width =6.12m
