500x500mm Full Flip Chip Common Cathode Curved COB LED Display

What is COB LED SCREEN?

COB (Chip on Board) is a kind of led display packaging technology. Unlike traditional LED screens, COB technology involves mounting multiple LED chips directly onto a circuit board, eliminating the need for individual packaging. This consolidation enhances brightness, reduces heat emission, and enables a more seamless display.

COB vs. SMD: Key Differences

This product utilizes COB (Chip-on-Board) encapsulation technology, a significant advancement over traditional SMD (Surface-Mounted Device) methods. Below are the key distinctions and benefits:

Integrated Design

COB directly bonds RGB LED chips onto the PCB, eliminating the need for individual lamp soldering (as in SMD).

Advantage: Enhances reliability, color consistency, and protection against environmental factors.

No Backshell Design

The lamp board directly contacts the structural frame, improving display surface flatness and reducing light refraction gaps.

Durability in Rental Scenarios

Proprietary sealing technology addresses SMD’s vulnerability to lamp bead dislodgement during frequent transport and setup.

Performance Benefits

Higher pixel density and viewing angles (e.g., 170°×170°) compared to SMD.

Superior heat dissipation due to direct PCB bonding, extending lifespan.
