How to calculate the size of led display

1. The calculation method of indoor led display.
Give the specific data of the screen (length, width, area)
Example: The specification of the screen is Φ5 (referring to the diameter of the pixel) screen, the screen is 5.8 meters long and 2.6 meters wide.
A. First of all, it is clear that the technical parameters of the Φ5 screen unit board specification is ×, and the unit board resolution is 64×32
B. Calculate the number of cell boards used.
Number of boards used for screen length or width = pre-made screen length or width ÷ unit board length or width
The number of boards used for screen length: 5.8 meters × ÷ = 11.89 ≈ 12
The number of boards used for screen width: 2.6 meters × ÷ = 10.65 ≈ 11
C. Calculate the actual screen size.
Actual screen length or width = unit board length or width × number of blocks for screen length or width
Actual screen length: × 12 = 5. meters
Actual screen width: × 11 = 2. meters
D. The area of ​​the screen: 5.×2.=15.72 (square meters)
Note: Usually, the size of the outer frame of the clearing screen is based on the size of the screen and 5- is added to each side.
E. The resolution of the screen = the number of boards used for the screen × the resolution of the unit board
Screen resolution = (12×64)×(11×32)

2. Only the area of ​​the screen is given, no length and width.
Example: Make a screen with an area of ​​9㎡, and the specification of the screen is Φ5 (referring to the diameter of the pixel).
A. If only the area is given, we have to calculate the length and width by ourselves. It can be calculated according to the ratio of length and width 4:3 or 16:9. This picture effect is good. (Take 4:3 as an example here)
B. Theoretical screen length is: length = (area ÷ 12) square root × 4
Width = square root of (area ÷ 12) × 3
That is: length = 3.
width=2.
C. The length and width have been calculated. See the example in (1) for the calculation below.

3. The calculation method of the outdoor display.
Give the specific data of the screen (length, width, area).
Example: The outdoor full color screen to be made is about 10 meters long and 6 meters wide
A. First of all, it is clear that the specification of the unit box (length and width of the box) is ×, and the resolution is 64 × 48
B. Calculate the number of boxes.
Number of boxes for screen length or width = pre-made screen length or width ÷ unit box length or width
The number of cabinets for screen length: 10 meters × ÷ = 7. ≈ 8
The number of cabinets for screen width: 6 meters × ÷ = 6.25 ≈ 6
C. Calculate the actual screen size.
Actual screen length or width = the (specification) length or width of the cabinet × the number of cabinets used for the screen length or width
Actual screen length: ×8=10.24 meters
Actual screen width: ×6=5.76 meters
D. Area of ​​screen: 10.24×5.76=.≈.98(square meter)
E. Resolution of screen = resolution length and width of cabinet × length and width of cabinet = (64×10)×(48×6)
