LED Display Screen Technical Description
An LED display screen is a high-performance digital display technology that uses an array of light-emitting diodes (LEDs) to produce vibrant, high-resolution visuals. These screens are widely used in advertising, live events, sports stadiums, control rooms, and retail environments due to their superior brightness, energy efficiency, and durability.
LED Modules: The building blocks of the display, consisting of multiple LED chips (SMD or DIP) arranged in a matrix.
Cabinet Structure: Modular panels (typically aluminum alloy) designed for easy installation and maintenance.
Control System: Includes sending cards, receiving cards, and video processors for signal transmission and image processing.
Power Supply: Redundant switching power units (e.g., 48V DC) for stable operation.
Cooling System: Fans or passive heat dissipation to prevent overheating.
| Parameter | Description |
|---|---|
| Pixel Pitch (P) | Distance between LED centers (e.g., P2.5 = 2.5mm; smaller = higher resolution) |
| Brightness | Indoor: 800–4,500 nits; Outdoor: 5,000–10,000 nits (sunlight-readable) |
| Refresh Rate | ≥3,840Hz (eliminates flicker in camera recordings) |
| Viewing Angle | 140°–160° (horizontal/vertical) |
| Contrast Ratio | ≥5,000:1 (deeper blacks, vivid colors) |
| IP Rating | IP65 (dustproof/waterproof) for outdoor models |
| Lifespan | 100,000+ hours (with proper maintenance) |
Indoor LED Screens: High resolution (P1.2–P4), moderate brightness, lightweight.
Outdoor LED Billboards: High brightness (5,000+ nits), weatherproof (IP65), large pixel pitch (P4–P10).
Rental LED Screens: Lightweight, quick-install frames for events/stages.
Transparent LED Screens: 50%–70% transparency for retail/storefronts.
Fine-Pitch LED (COB/MicroLED): Ultra-HD (P0.7–P1.8) for broadcast studios.
✔ Superior Image Quality: 4K/8K resolution, wide color gamut (100% NTSC).
✔ High Brightness & Visibility: Clearly visible in direct sunlight.
✔ Energy Efficient: 30–50% lower power consumption than traditional displays.
✔ Modular Design: Easy repair/replacement of faulty modules.
✔ Long Lifespan: 10+ years with minimal degradation.
Advertising: Digital billboards, mall signage.
Live Events: Concerts, conferences, sports broadcasts.
Control Rooms: Real-time data monitoring.
Retail & Hospitality: Interactive menus, promotional displays.
Daily: Dust removal with anti-static brushes.
Monthly: Check cable connections and cooling systems.
Annually: Professional calibration for color consistency.
Avoid: Static images >24 hours (prevents burn-in), high-pressure water sprays.
MicroLED: Ultra-thin, higher brightness, and longer lifespan.
AI Integration: Auto-brightness adjustment, predictive maintenance.
5G + 8K: Real-time ultra-HD streaming.
