In security monitoring, command dispatch, video conferencing, and broadcasting, display clarity and reliability directly impact decision-making. As pixel pitches enter the micro era, traditional SMD technology is approaching its physical limits –COB (Chip on Board) packaging is becoming the industry standard. The FOCONO COB Series represents a mature implementation of this technological evolution.

1. COB Packaging: Three Fundamental Upgrades

Traditional SMD mounts individually packaged LED lamps onto a PCB. COB, by contrast, directly bonds bare LED chips onto the board and encapsulates them with a conformal coating. This difference delivers three key improvements:

Enhanced Protection – The conformal coating fully shields chips from moisture, dust, and physical impact –dramatically reducing dead pixels, with a cleanable surface.

Optimized Heat Dissipation – Direct chip‑to‑PCB attachment shortens the thermal path, ensuring stable long‑term operation.

Superior Display Consistency – Minimized optical variation between pixels maintains excellent gray scale and color uniformity even at low brightness, reducing visual fatigue.

2. Five Models for Every Viewing Distance

The COB Series includes COB‑06 (P0.625), COB‑07 (P0.78), COB‑09 (P0.93), COB‑12 (P1.25), and COB‑15 (P1.5625) – with pixel density up to 2,560,000 dots/m², covering everything from close‑up command centers to mid‑distance meeting rooms.

All models support 14‑16bit gray scale, 3840‑7680Hz refresh rates, 200‑1000nits brightness,and 2000‑12000K color temperature – adapting to diverse indoor lighting conditions.

3.Differentiated Design for Tangible Value

Ultra‑Thin – Just 28mm thick, freeing up space and blending into any interior.

54‑Inch Large‑Format Units – Reducing installation seams and workload, with front/rear maintenance access. 

High Compatibility – Supporting SMD, COB, IMD, and MIP packaging – future‑proofing your investment.

4. Empowering Four Core Scenarios

Security Monitoring & Command Dispatch – Ultra‑fine pitch captures every critical detail –license plates, facial features, map markings – with rich shadow detail even at low brightness.

Video Conferencing – Ultra‑high refresh rates and color accuracy deliver natural remote collaboration.

Broadcast &Production – 3840‑7680Hz refresh rates eliminate scan lines and flicker for professional recording and live streaming.

Exhibition &Commercial Display – Large‑format units enable seamless splicing for immersive visual experiences.

5. 17 Years of Quality – Backing Every Screen

With a 100,000‑hour lifetime, ‑10°C to +40°C operating range, and global voltage compatibility, the COB Series is built on FOCONO 17‑year expertise in LED display – ensuring reliability where it matters most.

Technology Empowers Scenarios, Display Creates Value

COB packaging is redefining indoor professional display standards. The FOCONO COB Series – with complete pitch coverage, ultra‑thin design, large‑format units, and high compatibility – delivers high‑value solutions for professional indoor applications.
