Full color LED display needs to know that knowledge
In today's world, the application of full-color LED displays has become increasingly widespread. From digital billboards to indoor signage and large-scale outdoor screens, these displays are now an essential part of modern visual communication. In this article, we will walk you through some fundamental knowledge that every user or professional should understand about LED displays.
1. **Pixel Spacing Calculation**
The pixel pitch is the distance between the centers of adjacent pixels. Common pitches include P16 (16mm), P20 (20mm), and P10 (10mm). The smaller the pitch, the higher the resolution and image clarity.
2. **Length/Height Calculation**
To calculate the dimensions of a screen, multiply the pixel pitch by the number of pixels. For example:
- 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. **Module Number Calculation**
The number of modules required is calculated by dividing the total area by the module’s length and height.
For instance, for a 10m² PH16 outdoor full-color LED display:
10 ÷ 0.256 ÷ 0.128 ≈ 305 modules
4. **Visual Distance Calculation**
Different distances define how viewers perceive the screen:
- **RGB Mixing Distance**: Pixel Pitch (mm) × 500 / 1000
- **Minimum Viewing Distance**: Pixel Pitch (mm) × 1000 / 1000
- **Best Viewing Distance**: Pixel Pitch (mm) × 3000 / 1000
- **Maximum Viewing Distance**: Screen Height (m) × 30
5. **Scan Method Calculation**
The scan method refers to how many rows are lit at once. Indoor single/dual color typically uses 1/16 scan, while full-color indoor uses 1/8. Outdoor screens often use static scanning for better brightness and stability.
6. **Power Supply Calculation**
Calculating the power supply involves considering the voltage, current, and pixel density. For example, a 5V40A power supply can support up to 8 modules for a P10 screen. Total power requirements depend on the number of modules and their configuration.
7. **Display Power Calculation**
Power is calculated using the formula P = UI. Each LED lamp consumes approximately 0.1W, and the total power depends on the number of pixels and the scan mode.
8. **Brightness Calculation**
The overall brightness of the screen is determined by the brightness of individual LEDs. For example, with 2500 pixels per square meter and a brightness of 5000 CD/m², each red, green, and blue LED contributes differently based on color balance.
9. **Screen Resolution Calculation**
Resolution is calculated as 1 divided by the square of the pixel pitch. For P16, it would be 1/(0.016×0.016) = 3906 dots per square meter.
10. **Optimal Viewing Angle Selection**
Choosing the right viewing angle ensures optimal visibility. Indoor SMD LEDs typically offer horizontal angles of 120–160 degrees, while outdoor DIP LEDs have narrower angles due to environmental factors.
Understanding these key aspects of LED displays helps in selecting the right equipment, optimizing performance, and ensuring a great visual experience for the audience. Whether you're setting up a small indoor screen or a large outdoor display, these fundamentals are essential for success.
