How to Choose the Right LED Display Model: A Guide to Pixel Pitch, Resolution, and Application Scena

When investing in an LED display, especially for commercial or professional use, selecting the right model is crucial for visual impact and cost efficiency. With various pixel pitches like P1.2, P2, P3, and resolutions ranging from 720P to 4K, understanding how to match specifications with actual application needs is essential.

📌 What Does Pixel Pitch Mean in LED Displays?

In the LED display industry, models such as P2, P3, or P5 indicate pixel pitch, measured in millimeters. For example, a P2 screen indicates a 2mm gap between each pixel. The smaller the pitch, the higher the pixel density and resolution per square meter. A P2 screen typically contains 250,000 pixels per square meter, making it suitable for high-definition indoor environments.

📺 Resolution and Viewing Distance

• 720P (HD): Suitable for general commercial ads and retail spaces, recommended pixel pitch P3–P5 depending on viewing distance.
• 1080P (Full HD): Ideal for meeting rooms, showrooms, or indoor advertising, recommended pitch P1.8–P2.5.
• 4K: High-end applications like luxury showrooms or command centers. Requires P1.2–P1.5 with large screen areas (20㎡+).

Formula for viewing distance:

Minimum Viewing Distance (meters) ≈ Pixel Pitch (mm) × 1.5

Example: A P2 screen is best viewed from at least 3 meters to avoid visible pixelation.

🏢 Application-Based Recommendations

Application Scenario	Recommended Pixel Pitch	Resolution Level
Indoor Advertising	P2–P3	1080P
Outdoor Billboards	P6–P10	720P or lower
Corporate Meeting Rooms	P1.5–P2.5	1080P / 4K
Concert Stages & Events	P4–P8	Visual Impact Only
Control Centers / Museums	P1.2–P1.8	4K Ultra-HD

📐 How Area Affects Resolution

The display area directly impacts achievable resolution. For example:

• A 10㎡ P2 screen ≈ 2K (1080P) resolution
• A 35㎡ P2 screen ≈ 4K resolution. If the installation space is limited, a smaller pixel pitch (like P1.2) is needed to achieve higher resolution, though this increases cost significantly.

💡 Final Tips for LED Display Buyers

• Don’t over-invest in ultra-high resolution where it’s not needed.
• Consider the installation environment, content type, audience distance, and budget.
• Collaborate with experienced LED suppliers to accurately calculate pixel density versus area.
