COB Series — High-Density Chip-on-Board LED Displays
The COB Series uses Chip-on-Board packaging: Micro LED chips are mounted directly onto the circuit board with no exposed lamps. The surface is one smooth, robust plane — built for close viewing, fine pitch, and tough environments.
What “COB” Means in Plain Terms
In traditional SMD screens, each LED sits in its own packaged lamp that can be knocked loose. In COB, the chips are bonded straight to the board and covered by a protective layer. Fewer failure points, better uniformity, and a panel you can practically press your face against.
Why Choose COB
- Fine pixel pitch (down to ~1.2 mm) — sharp at close distance.
- No exposed lamps — resistant to impact and moisture.
- High contrast & uniformity — no visible pixel gaps.
- Low maintenance — fewer dead pixels over time.
- Wide viewing angle — consistent from the side.
Where COB Fits
- Corporate lobbies & offices
- Stages & events
- Churches & worship
- Control rooms & broadcast studios
- High-end indoor fixed installs

Frequently Asked Questions
Is COB better than SMD?
For close-view and high-reliability installs, yes. COB has no loose lamps and a smoother surface, so it stays sharp and durable longer.
