LED Display Dot Pitch, Module Size, and Viewing Distance Calculation

Release date: 2017-11-29 Source: LED Network Share:

When designing an LED display system or estimating the project cost, it's essential to understand how to calculate the dot pitch, module size, and viewing distance. These factors play a crucial role in ensuring the display meets the desired visual quality and performance standards. In this article, we'll walk you through the basic concepts and formulas for calculating these key parameters.

Dot Pitch Calculation

The dot pitch refers to the distance between the centers of two adjacent pixels. It is usually measured in millimeters (mm). For example:

• P16 = 16 mm
• P20 = 20 mm
• P12 = 12 mm

Each pixel can consist of one LED (e.g., PH10 - 1R), two LEDs (e.g., PH16 - 2R), or four LEDs (e.g., PH16 - 2R1G1B).

Relationship Between Dot Pitch and Module Size

1. Module Length

Module length = Number of pixels along the long side × Dot pitch

Example: For a P16 module, if there are 16 pixels on the long side: 16 × 1.6 cm = 25.6 cm

2. Module Width

Module width = Number of pixels along the wide side × Dot pitch

Example: For a P10 module with 32 pixels on the long side: 32 × 1.0 cm = 32 cm

Full Screen Resolution Calculation

1. Cabinet Resolution

Cabinet resolution = (Length × Width) / Dot pitch

2. Full Screen Resolution

LED display screen per square meter = 1,000,000 / Dot pitch (in mm)

Calculating the Number of Modules Used

Method 1: Total area ÷ Module length ÷ Module height = Number of modules used

Example: For a 10 m² P16 outdoor monochrome LED display: 10 ÷ 0.256 ÷ 0.128 ≈ 305 modules

Method 2 (More Accurate): Number of modules along length × Number of modules along height = Total number of modules

Example: For a 5m x 2m P16 display:

• Modules along length: 5 ÷ 0.256 ≈ 19.53 → Round up to 20
• Modules along height: 2 ÷ 0.128 ≈ 15.26 → Round up to 16
• Total modules: 20 × 16 = 320

LED Display Viewing Distance Calculation

RGB Color Mixing Distance: LED full-color screen viewing distance = Dot pitch (mm) × 500 to Dot pitch (mm) × 1000

Minimum Viewing Distance: LED display visible distance = Dot pitch (mm) × 1000

Optimal Viewing Distance: Best viewing distance = Dot pitch (mm) × 3000 to Dot pitch (mm) × 1000

Maximum Viewing Distance: LED screen farthest viewing distance = Screen height (m) × 30
