How to calculate the visual distance and dot spacing of the LED display?

1. Calculation method of visible distance of LED display :
RGB color mixing distance three colors mixed into a single color LED display distance: LED full color screen line of sight = pixel point spacing (mm) × 500 / 1000
The minimum viewing distance can display the distance of the smooth image: LED display visible distance = pixel spacing (mm) × 1000/1000
The most suitable viewing distance The viewer can see the distance of the highly clear picture: the best viewing distance of the LED display = pixel spacing (mm) × 3000 / 1000
The farthest viewing distance: LED screen farthest viewing distance = screen height (m) × 30 (times)
2. Point spacing calculation method: the center distance between each pixel point and each adjacent pixel point; each pixel point can be an LED light [eg PH10(1R)], two LED lights [eg: PH16 (2R)], three led lights [such as: PH16 (2R1G1B)], P16 point spacing: 16MM; P20 point spacing: 20MM; P12 point spacing: 12MM...
3, length and height calculation method: point spacing × points = length / height
Such as: PH16 length = 16 points × 1.6cm = 25.6cm height = 8 points × 1.6cm = 12.8cm
PH10 length = 32 points × 1.0cm = 32cm height = 16 points × 1.0cm = 16cm
4, LED display screen using the number of modules calculation method: total area ÷ module length ÷ module height = use the number of modules
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
More accurate calculation method: length using module number × height using module number = total number of modules used
Such as: length of 5 meters, height 2 meters PH16 monochrome led display using the number of modules:
Long use module number = 5 meters ÷ 0.256 meters = 19.53125 ≈ 20
High number of modules used = 2 meters ÷ 0.128 meters = 15.26 ≈ 16
The total number of modules used = 20 × 16 = 320

Home and indoor or building air filters remove unwanted particles like dust, pollen, pet dander and mold and ensure even the most allergy prone can breathe easily year–round. However, choosing the right filter for your home can be a rather involved process. To help, here are the most common indoor air filters and what each of them provides. The filters are the simplest basic component for air filtration solution through your heating and cooling system ,It is important that you constantly monitor the buildup of debris on these filters as well because it can easily be recycled into the air supply. It is easy change and maintain.
