How to calculate the dot pitch of the LED display
2019-04-29 16:20:30
1. 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 [eg PH16 (2R1G1B)], P16 point spacing: 16MM; P20 point spacing: 20MM; P12 point spacing: 12MM...

2. 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

3. The number of modules used in the screen is calculated: total area ÷ module length ÷ module height = number of modules used

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 of 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 = 15.625 ≈ 16

The total number of modules used = 20 × 16 = 320

4. LED display screen distance calculation method:

RGB color mixing distance three colors mixed into a single color distance: LED full color screen line of sight = pixel point spacing (mm) × 500 / 1000

The minimum viewing distance can show 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 high-definition picture: LED screen best line of sight = pixel point spacing (mm) × 3000/1000

The farthest viewing distance: LED screen farthest viewing distance = screen height (m) × 30 (times)
