3. Outstanding COB Display Performance (Compared with Traditional SMD)
Superior Image Quality
Ultra-high contrast ratio: COB version reaches ≥10000:1, far exceeding SMD’s less than 5000:1, presenting deeper black levels and layered pictures
Wide color gamut: Adopts high-quality wide-gamut LED chips, covering ≥95% DCI-P3 color gamut for vivid, authentic color reproduction
Ultra-wide viewing angle: Horizontal and vertical viewing angles both up to 170°, no color shift or brightness attenuation from side perspectives
High grayscale expression: COB panels support 14–16bit grayscale, while SMD only reaches 12–14bit; richer color gradation for delicate picture details
Adjustable high brightness: 1000–3500 nits adjustable brightness, adapting to both indoor dim environments and bright outdoor venues
Smooth Dynamic Picture Experience
Ultra-high refresh rate (3840–7680Hz) and 0.3ms ultra-low response time, supporting 1–120Hz adjustable frame rate
Eliminates stuttering, image tearing and ghosting for ultra-smooth playback of fast-moving frames such as racing footage and live performance dynamic shots
Optimized motion detail restoration, clearly capturing tiny dynamic elements including splashing dust and high-speed rotating components
Higher Protection & Stability
Superior IP rating: COB surface protection reaches IP65, versus IP41 of conventional SMD panels; effectively dustproof, waterproof and anti-collision
Integrated COB packaging technology enhances overall structural stability, anti-impact and anti-damage capacity, more suitable for frequent rental transportation and repeated disassembly
Excellent heat dissipation structure ensures long-term stable operation without color drift under continuous high-load work
Covers ultra-fine pitch HD to large-pitch long-distance viewing specifications, supporting Full HD (1920×1080) and Ultra HD (3480×2160) display effects
4. Electrical & Environmental Parameters
Power performance: Peak power consumption 450–650W/m², average power 180–260W/m²; adjustable refresh rate reduces unnecessary power loss
Power input: Universal AC 100–240V, 50/60Hz wide voltage power supply
Working environment: Operating temperature -10℃ ~ +45℃; humidity 10%–80% RH (non-condensing)
Long service life: Up to 100,000 hours of stable service life
Fine flatness: Cabinet flatness controlled within ≤0.1~0.15mm, seamless splicing effect after assembly
5. Main Application Scenarios
