How to choose the size of outdoor and indoor LED displays?LED screens can be seen everywhere in life,such as display screens,broadcast screens,etc.,but do you know how to calculate the size of LED?Only Optoelectronic Technology takes us to understand the calculation method of led screen size.
1.Common models and sizes of LED screens
LED screens are generally made of unit boards.The common models and sizes(mm)of LED unit boards are as follows:
2.Calculation of indoor LED screen
After understanding some basic data above,we can look at it through an example.
Example:If you need an indoor full-color LED screen whose length and width are 4m and 3m respectively,and use a P10 screen,how to calculate its actual length and height?
Maybe some friends don't understand what this question means.Since there are already length and width,why do we need to calculate them?
Because the large LED screen is composed of multiple unit boards,it is necessary to calculate how many unit boards are needed for a large screen with a length of 4m and a width of 2m.
1.First,calculate how many unit boards are needed for length and height(divide the length of the whole screen by the length of the unit board,round up an integer)
Long:We learned the basic data of p10 from the above,and the number of modules is calculated as:
Length:4m/0.32m=12.5 pieces≈13 pieces.
Width:3m/0.16m=18.7pcs≈19pcs
Because the minimum unit of the module is 1,it must be rounded up.
2.Actual length and height dimensions(multiply the number of unit boards required by the size of a single unit board)
Length:13*0.32=4.16m,
Width:19*0.16=3.04m
3.Actual LED screen area:Therefore,the LED length is 4.16*3.04m.
3.Calculation of outdoor led screen
Outdoor LEDs are spliced by cabinets.Compared with modules,the size of cabinets is more,but the calculation method is similar,and the last number needs to be rounded to calculate the screen size.
4.Calculation of LED screen at door head
Walking on the street,I can see that the rectangular LED display screens on the doors of banks and shops are playing advertisement subtitles.We usually refer to them as door LED screens,LED bar screens or LED walk-in text screens for short.
So what are the specifications of the door LED display?How to determine the screen size?In fact,it is almost the same as indoors.
Example:A store customizes a P10 monochrome LED display(320*160),and intends to make a scrolling screen with a length and width of 3.5 meters x 0.8 meters.How to calculate the actual size of the door LED display?
1.First,calculate how many unit boards are needed for length and height(divide the length of the whole screen by the length of the unit board,round up an integer)
Length:3.5m÷0.32=10.9375≈11
Height:1m÷0.16=5≈5
2.Actual length and height dimensions(multiply the number of unit boards required by the size of a single unit board)
Length:11×0.32=3.52m
Height:5×0.16m=0.96m
3.Actual LED screen area:3.52m×0.96m=3.3792㎡
What needs to be added is that the door LED display screen also has a frame size.Since there are many specifications of frame profiles,the commonly used frame thickness is 9 cm.Width plus 3.5cm(one side);there is also width plus 4.5cm(one side)
Assuming that the frame we use here is 3.5cm on one side,the length and width of the door LED display are as follows:
The whole screen length:3.52m+0.035*2=3.59m
The whole screen height:0.96+0.035*2=1.03m
Therefore,the actual entire screen area:3.59m×1.03=3.6977㎡
