COB Display

What’s COB?

COB, called chip on board, puts LED chips on the PCB board directly.

COB Advantage:

1. Smaller Pixel Pitch.

Without diameter of single pixel, pitch could be smaller .

Reduce frame cost, lower heat resistance of chips, achieve high density package.

2. High reliability.

Without bare pixel foot, heat radiation by PCB board, more stable and reliable.

3. Cost-effective.

High package efficiency decrease cost.

4. Ultra Wide Viewing Angle.

Ultra wide 170 ° vie wing angle bring good visual experience.

5. Better Physical Protective Performance. 

Full-board sealed with ethoxyline resin, with waterproof, 

moisture-proof, dust-proof, anti-collision, anti-oil, anti-oxidation, 

anti-static, wear-resistant, easy to clean characteristics.

6. High Contrast Ratio.

10000:1 contrast ratio, vivid picture, florid color and perfect viewing effect.

7. Low Brightness and High Grey Level.

With low brightness and high grey level, showing florid color, delicate picture.

8. Safety  Eye Protection.

COB product's high fill factor optical design, uniform illumination, 

reducing glare and glare; reducing blue light damage, 

safe for the human eye, effectively reducing viewing fatigue.

9. Perfect Scale 16:9.

600*337.5mm standard cabinet  size, follow scale 16:9,

easy to combine 2K/4K/8K standard big screen.
