COB VS SMD LED Display: Technical Comparison
Qu'est-ce que le COB ?
COB (Chip On Board) technology is a new LED packaging technology. Different from the traditional SMD surface-mounting packaging, it integrates light-emitting chips into PCB instead of welding them to PCB. 
Lien Highlight
With ultra-high contrast ratio and ultra-high refresh rate,the whole screen is more vivid, also effectively suppress Moire and reducing light refraction and making colors more concentrated
Advanced flip chip technology to deliver comprehensive, 360° all-around protection against external impacts, ensuring robust defense from every angle.

High Refresh for Camera- Friendly Écran LED pour salle de réunion
With a refresh rate of 3840–7680Hz, Nexus Series is suitable for:
Broadcast studios,Virtual production support environments,Corporate event stages,Live-streaming and filming spaces
Front Maintenance Design
All cabinets support full front access, allowing module replacement from the front without rear maintenance space. This simplifies installation in control rooms, wall-mounted systems, and tight indoor environments.
Choosing the Right Pixel Pitch

Foire aux questions
What is the difference between P0.9375 and P1.25?
P0.9375 offers significantly higher pixel density than P1.25, making it better for close-viewing environments such as command centers and broadcast monitoring walls. P1.25 is often the better fit when viewers are farther away and the project budget needs tighter control.
Why does refresh rate matter?
A higher refresh rate improves camera performance and reduces flicker, scan lines, and rolling artifacts. With 3840–7680Hz, Nexus Series is suitable for camera-facing and broadcast-related applications.
Is front maintenance available on all models?
Yes. All Nexus Series cabinets support front maintenance, which is important for wall-mounted or space-limited installations.
What certifications are available?
Nexus Series supports CCC, CE, RoHS, FCC, and PSE, covering major international compliance requirements.
