The optimal viewing distance for a can-shaped LED display screen needs to be calculated by combining pixel pitch (P-value) and the specific application scenario. The core formula is: Optimal Viewing Distance = Pixel Pitch (mm) × Coefficient. The coefficient range is usually 300-1000, and needs to be adjusted according to the scenario:
1. General Calculation Formula
Basic Formula: Optimal Viewing Distance = Pixel Pitch × 300~1000 (unit: meters).
For example: The viewing distance for a P10 screen is 10mm × (300~1000) = 3 meters to 10 meters.
Detailed Scenario:
High-speed advertising: Coefficient 500~1000 (for long-distance viewing).
Commercial areas: Coefficient 300~600 (for medium to close distances requiring high definition).
2. Scenario-Specific Adjustments
High-speed advertising: Due to high vehicle speeds, a larger viewing distance is required (e.g., for a P10 screen, 10 meters or more is recommended).
Commercial areas: High foot traffic necessitates a balance between clarity and cost (e.g., 2.5-5 meters is recommended for P5 screens).
3. Other influencing factors:
Ambient light: Increase viewing distance by 20%-30% in strong light.
Screen size: A comfortable viewing distance is 1.5-3 times the diagonal length.
(Note: The above formulas are industry standards and should be adjusted based on product parameters and on-site testing.)
