III. Electrical Parameters: The "Reliability Indicators" for Stable Operation
Electrical parameters govern power supply safety, power consumption control, and long-term reliability, serving as key references for project implementation.
1. Power Consumption (Peak/Average)
Peak Power Consumption (W/m²): Maximum power consumption when the display shows an all-white image (e.g., 350W/m² for P0.9375), the basis for power supply system design.
Average Power Consumption (W/m²): Typical power consumption during daily video and document playback (e.g., 120W/m²), determining long-term electricity costs. COB packaging offers higher luminous efficiency, delivering notable low-power advantages and greater energy efficiency than traditional SMD displays.
2. Power Supply Requirements & Driving Mode
Power Supply (AC100~240V): Wide-voltage design compatible with global power grid standards, preventing damage from voltage fluctuations.
Driving Mode (Common Cathode/Common Anode): Common cathode driving is mainstream energy-saving technology, reducing power consumption and heat generation while extending LED chip lifespan and enhancing color performance compared to traditional common anode driving. Most specifications support both common cathode and common anode driving to adapt to diverse power supply solutions.
IV. Processing Performance: The "Core Support" for Smooth Display
Processing performance determines the smoothness, sharpness, and compatibility of dynamic images, a critical indicator for professional scenarios like command centers and studios.
1. Refresh Rate & Frame Rate
Refresh Rate (≥3840Hz): The number of times the display refreshes per second. A higher value delivers stable images free of flicker or scan lines, ideal for live broadcast shooting, eliminating moiré patterns and water ripples in camera footage.
Frame Rate (50&60Hz): Supports mainstream video signal frame rates, ensuring smooth playback of diverse video sources without lag or frame drops.
2. LED Display Scanning Method
The scanning method of an LED display refers to the driving control mode of lighting lamp beads row by row/column by column, divided into static scanning and dynamic scanning.
① Static Scanning
Each lamp bead is driven independently and lit continuously.
Advantages: High brightness, excellent contrast, stable image, no flicker.
Applications: Fine-pitch, high-definition, close-view scenarios, high-quality indoor displays.
② Dynamic Scanning
Multiple rows of lamp beads share one driving circuit, lit alternately via fast row/column refresh, forming continuous images through human visual persistence.
Scan Ratios: 1/4, 1/8, 1/16, etc. Larger denominators mean higher scan counts.
Characteristics: Simplified circuitry, lower cost, reduced power consumption.
Tradeoffs: Corresponding reductions in brightness, contrast, and refresh rate.
③ Selection Logic
Outdoor large screens: Prioritize low-scan or static scanning for high brightness and stability.
Conventional indoor displays: Typically use 1/8 or 1/16 dynamic scanning to balance cost, power consumption, and display quality.
3. Gray Scale & HDR Support
Gray Scale (≥13bit): Defines brightness adjustment precision. Higher bit depth delivers smoother light/dark transitions and richer layering from pure black to pure white, eliminating color banding.
HDR10 Support: Enables high dynamic range display, enhancing highlight and shadow details for lifelike video images, aligning with current high-definition video standards.
4. LED Lifespan
The specified LED lifespan of ≥100,000 hours refers to the theoretical lifespan of LED chips (time for brightness to decay to 70% of the initial value). With 8 hours of daily use, this exceeds 30 years, highlighting the reliability advantages of fully flip-chip COB technology.
V. Usage Parameters: The "Practical Indicators" for Long-Term Operation & Maintenance
Usage parameters govern installation environment adaptability, maintenance convenience, and long-term stability, serving as critical references throughout the project lifecycle.
1. IP Protection Rating (IP54)
Indicates the LED surface protection capability. IP54 means dust protection Level 5 (prevents harmful dust accumulation) and water protection Level 4 (resists splashing water ingress), meeting indoor environment protection requirements, reducing dust and moisture impact on LED chips, and lowering maintenance frequency.
2. Temperature & Humidity Range
Operating Temperature: -10~40°C; Storage Temperature: -20~60°C. Adapts to complex temperature environments, preventing performance degradation or damage from extreme temperatures.
Humidity: 10~90%RH (non-condensing). Non-condensing is critical—condensation causes short circuits and chip oxidation, requiring moisture-proof design in humid environments.
Conclusion: Selection Logic Behind Parameters
No LED display parameter exists in isolation; all are interconnected and tailored to specific scenarios. Command centers require high refresh rates and gray scales for clear, stable monitoring images; conference rooms demand moderate brightness and wide viewing angles for multi-viewer comfort; studios prioritize refresh rate and moiré control.
Understanding specification sheets means not only grasping technical indicators but also selecting "performance-cost matched" solutions aligned with project needs. The advent of fully flip-chip COB technology has comprehensively upgraded fine-pitch LED displays in sharpness, reliability, and display quality—parameters that directly reflect these technical advantages.
