Introduction to LED Display Manufacturing
LED displays are essential for commercial advertising, stadiums, and hotels. Building one requires technical expertise and quality components. Shanghai HARSELED specializes in LED full-color display solutions, offering end-to-end services from R&D to installation.

Materials Needed to Build an LED Display
- LED Modules: Core components for brightness and color accuracy.
- Cabinet Frame: Durable aluminum or steel for structural support.
- Control System: Processors and software for content management.
- Power Supply: Stable voltage regulators for safety.
- Cables and Connectors: High-quality wiring for seamless connectivity.
Pro Tip: Choose IP-rated materials for outdoor displays to resist weather damage.
Step-by-Step Guide to Building an LED Display
Step 1 – Design Your LED Display
- Define the display size and resolution (e.g., P3, P4, P5 pixel pitch).
- Use CAD software to map module placements.
- Shanghai HARSELED provides custom LED display solutions tailored to your needs.
Step 2 – Assemble the Cabinet Frame
- Weld or bolt the frame for stability.
- Ensure proper ventilation to prevent overheating.
Step 3 – Install LED Modules
- Mount modules evenly to avoid gaps.
- Secure connections with waterproof connectors for outdoor use.
Step 4 – Connect the Control System
- Link modules to a central processor (e.g., Novastar or Linsn).
- Install configuration software for content scheduling.
Step 5 – Power and Testing
- Connect to a stable power source (220V recommended).
- Test brightness, color uniformity, and dead pixels.
Key Factors for High-Quality LED Displays
- Pixel Pitch: Smaller pitch = higher resolution (ideal for close viewing).
- Brightness: 1500-8000 nits for outdoor displays.
- Refresh Rate: ≥3840Hz to reduce flickering.
- Durability: IP65 rating for dust/water resistance.
Case Study: Shanghai HARSELED’s stadium displays use SMD LED technology for superior performance in bright environments.
Common Applications of LED Displays
