LED display specifications and screen size calculation method
led screen in life, everywhere, display screen, broadcast screen and so on, but led size how to calculate, do you know? Today we together to understand the led screen size calculation method.
1, each unit board common model and size
LED screen is commonly formed with unit board assembly. led unit board common model and size (mm) corresponds to the following.
Conventional indoor full color led display: (detailed size parameters can be viewed on our website)
Conventional outdoor full color led display: (detailed size parameters can be viewed on our website)
Different specifications are also available for different applications
2、So how is it calculated?
One: the calculation of LED unit board
Here to HP8 and HP10 to give an example.
HP8 single unit board size: 256 * 128MM
HP8 model, the general module led point spacing of 32 points long, 16 points wide, and HP8 point spacing of 8mm. so the calculation.
PH10 single unit board size :320*160mm
With HP10 model, the general module led point spacing has 32 points in length and 16 points in width, while the point spacing of HP10 is 10mm, so the calculation.
Length = 32 points × 10mm = 320mm
height = 16 points × 10mm = 160mm.
And the data above is the same, the general is no need to calculate these, just need to understand the specific pixels of each model, you can calculate the size.
Second: the calculation of led display
Above we understand the above individual module calculation data after the LED display of the least unit are composed of a single unit board or box assembled. So that we can calculate the exact detailed size of a single screen by the size of the screen body on site, individually, we can see through an example.
Example one: indoor full color display calculation
If you need an indoor full color screen with a length and width of 4m and 3m led screen with P10, how to calculate its actual length and height dimensions?
Maybe some friends do not understand what this question means, since there is already the length and width, why do you need to calculate it? Because led large screen is composed of multiple unit boards, so to calculate the length of 4m, width 3m large screen need to use how many unit boards.
2-1, first of all, calculate the length and height of how many unit board needed (with the length of the whole screen divided by the length of the unit board, take the whole number)
We know the basic data of p10 from above, and its module number is calculated as
Length: 4m/0.32m = 12.5 ≈ 13.
width: 3m/0.16m = 18.7 ≈ 19
Because the smallest unit of module is 1, so it should be rounded.
2-2, actual length and height dimensions (multiply the number of unit panels needed by the size of individual unit panels)
2-3. Actual LED screen area: 4.16*3.04m=12.646㎡.
For example, two: outdoor full-color display calculation
Outdoor led using the box for splicing, the size of the box and the module compared, there are more, but the calculation method is similar! All need to be the last number of rounding to calculate the screen size.
Walking in the street or we go to survey the scene, I to see the building facade, store door head rectangular led display in playing advertising video, then the LED display specifications are how much? How to determine the size of the screen? In fact, it is similar to the indoor.
Need to customize a P10 outdoor full color LED display (320*160), and intend to make a screen with a length and width of 5m x 4m. How to calculate the actual size of the display?
1, first calculate the length and height of how many unit boards are needed (divide the length of the whole screen by the length of the unit board, take the whole number)
Long: 5m ÷ 0.32 = 15.625 ≈ 15 (in taking the value usually need to consider the size of the box, the size of the site installation environment allows. Optimal choice.)
High: 4m ÷ 0.16 = 25 ≈ 25
2, the actual length and height dimensions (multiply the number of required unit panels by the size of the individual unit panels)
3. Actual LED screen area.
Need to add is.
Outdoor LED display and the size of the edge, due to the side of the way there are many kinds of specifications.
Commonly used around the edge of the width of 20-50cm.
