Point distance and horizon calculation of LED display screen
Time:2017-07-15

We in the purchase of any a LED display, not to choose, but according to the environment we need to order to the ideal effect, which is inseparable from the LED display point spacing and line of sight (NLOS) calculated in this way it can play the greatest role in LED display.

First, point method to calculate the space: each pixel to between every adjacent pixel points of center distance; each pixel can is a single LED lamp (such as: PH10 (1R), two pieces of LED lights (such as: PH16 (2R), three pieces of LED lights (such as: PH16 (2R1G1B) and P10 point spacing for: 10mm; p16 point spacing for: 16mm; P18 point spacing for: 18mm.

Second, length and height calculation method: point spacing x point = length / height

Such as: PH16 length =16 * 1.6 cm =25.6 cm height =8 * 1.6 cm =12.8 cm

The length of PH10 =32 * 1 cm =32 cm height =16 * 1 cm =16 cm

Third, using the calculation method of the screen body module number: total area / length / height = using module module module number

Such as: 10 square PH16 outdoor monochrome LED display using the number of modules is equal to:

10 square meters, 0.256 meters, 0.128 meters =305.17678 = 305

A more accurate calculation method: the length of the number of modules used to use the number of modules = total number of modules

Such as: 5 meters long, 2 meters high PH16 monochrome LED display using the number of modules:

Long use module number =5 metres 83019 0.256 meters =19.53125 = 20

The use of high module number =2 metres 83019 0.128 meters =15.625 = 16

The total number of modules using =20 x 16 =320

Fourth, LED display visual distance calculation method:

RGB color mixed color mixing distance become the single color distance: LED full color = horizon pixel interval (mm) * 500/1000

The minimum viewing distance can display the distance of the smooth image: LED display can be regarded as distance = pixel spacing (mm) * 1000/1000

The most appropriate viewing distance viewer can see a high degree of clear picture of the distance: LED display the best distance = pixel spacing (mm) * 3000/1000

The most distant viewing distance: LED display the most distant horizon = screen height (m) x 30 (times).
