The three core differences in choosing an outdoor LED screen are pixel pitch, module technology, and chip grade. The specific differences are as follows:
I. Pixel Pitch: The core parameter determining price and applicable scenarios. Pixel pitch refers to the distance between the center points of the LED beads (unit: millimeters), directly affecting screen resolution, viewing distance, and price.
P10 (¥3k-4.5k/㎡)
Applicable scenarios: Community billboards, long-distance information display (e.g., viewing from 10 meters away).
Features: Low cost, but noticeable pixelation at close range ("mosaic" effect), suitable for scenarios with limited budgets and low image quality requirements.
P6-P5 (¥6.5k-7k/㎡)
Applicable scenarios: Transportation hubs, large plaza screens, mid-distance commercial displays (e.g., viewing from 5-10 meters).
Features: High cost-performance ratio, balancing image quality and cost, the first choice for mainstream applications.
P2.5 (¥6.8k+/㎡)
Applicable scenarios: High-end shopping mall naked-eye 3D screens, close-range high-definition displays (e.g., viewing within 5 meters).
Features: Exquisite image quality, but higher price; requires Micro LED technology (30%-50% more expensive than traditional screens by 2025, but significantly improved lifespan and image quality).
Avoidance Tips:
By 2025, P3 and below micro-pitch screens will have increased costs due to technological upgrades, but offer better long-term cost-effectiveness.
Choose pixel pitch based on viewing distance: P6/P8 for viewings over 10 meters, and below P3 for viewings within 5 meters.
II. Module Technology: Key Factors Affecting Durability and Energy Consumption
Module technology determines the LED screen's protection capabilities, lifespan, and operating costs; selection must be based on the usage environment.
SMD Surface Mount (Regular Price)
Features: LEDs are fixed using a surface mount process; waterproofing relies on external potting technology.
Suitable Scenarios: Dry environments, short-term use, or projects with limited budgets.
COB Integrated (15%-30% More Expensive)
Features: LEDs are directly soldered onto the circuit board; strong impact resistance, 20% longer lifespan, and high waterproof and dustproof rating.
Suitable Scenarios: Concerts, construction sites, and other high-frequency or harsh environments.
Common Cathode Driver (10% Premium)
Features: Reduces energy consumption through independent current control, saving approximately 50% on electricity costs, but initial costs are higher.
Suitable Scenarios:** Long-term operation and energy-saving scenarios (e.g., 24-hour advertising screens).
Purchase Recommendations:
In rainy areas, prioritize COB modules for moisture and drop resistance; choose common cathode drivers for scenarios with frequent power outages or energy-saving requirements; irregular designs (e.g., curved screens) require flexible modules.
III. Chip Grade: The Dividing Line Between Brightness and Stability
Chip grade directly affects the brightness, anti-attenuation ability, and price of the LED screen, requiring a trade-off based on usage needs.
Domestic Mid-Range Chips
Brightness: 5000-8000 nits, meeting the needs of small to medium-sized advertising screens.
Price: High cost-performance ratio, with a market share exceeding 70% by 2025, but still reliant on imports for the high-end market.
Suitable Scenarios: Community advertising, general commercial displays.
Imported High-End Chips
Brightness: Over 12000 nits, strong anti-fading capability, longer lifespan.
Price: 3 times more expensive than domestic chips, but with superior stability.
Suitable Scenarios: Airports, landmark buildings, and other scenarios with extremely high brightness requirements.
2025 Trends:
Domestic chip technology is gradually maturing, but the high-end market is still monopolized by imported brands; Small and medium-sized brand projects should prioritize domestic chips for better cost-effectiveness; For airports, landmarks, and other scenarios with sufficient budget, imported chips are recommended to ensure long-term stability.
Summary: 2025 Screen Selection Guidelines
Distance: Choose P6/P8 beyond 10 meters, P3 or below within 5 meters;
Distance: Choose COB for rainy conditions, common cathode driver for frequent power outages, flexible soft modules for irregular designs;
Distance: Domestic chips for small and medium-sized brands, imported chips for high-end scenarios.
By clearly defining needs and balancing parameters and costs, the most suitable outdoor LED screen solution can be efficiently selected.
