Walking on the street, you can see the rectangular led display screen above the door of banks and stores playing advertising subtitles. These screens are usually referred to as door head LED screen, LED strip screen or LED walking screen. So what is the specification of the door head LED display? How to determine the screen size, with such questions, and LCF editor to see:

At present, the door head LED screen is commonly made of semi-outdoor unit board.LCF semi-outdoor LED unit board common models and sizes (mm) correspond to the following:

P5.0 single-color 484 * 242

p5.0 double color 484*242

P10 single color 320*160

P10 double-color 320*160

P12.5 single color 400*200

P16 single color 256*128

P16 double color 256*128

Example: Customers in the Lianchengfa customized a half outdoor P10 monochrome LED display (320 * 160), reserved space can be used 3.5 meters × 1 meter. How to calculate the actual size of the door LED display?

1, first of all, calculate the length and height of how many unit boards are needed (using the length of the whole screen divided by the length of the unit board, take the integer) length: 3.5 ÷ 0.32 = 10.9375 ≈ 11 height: 1 ÷ 0.16 = 6.25 ≈ 6

2, the actual length and height dimensions (with the number of units required multiplied by the size of a single unit board)

Length: 11 × 0.32 = 3.52m High: 6 × 0.16m = 0.96m

3. Actual LED screen area: 3.52m × 0.96m = 3.3792 square meters

 LCF editorial reminds you, in practice, the door LED display there are border size, because the border profile has a variety of specifications, such as the common 9035, 9045.

9035-type frame, thickness of 9 centimeters, width plus 3.5 centimeters (one side); 9045-type frame, thickness of 9 centimeters, width plus 4.5 centimeters (one side)

Assuming that 9035 type frame is selected here, then 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

So the actual screen area: 3.59m × 1.03 = 3.6977 square meters
