COB Flip chip Common Anode and Common Cathode

Flip chip COB technology is LED Chips directly die bonding on PCB(printed circuit board), as bellowing:

There are two types of Flip-Chip COB:

Common Anode

Common Cathode

Advantage of Common Cathode 

1. RGB separate power supply

2. No external resistors

3. High precision voltage control

4. Low heat dissipation

5. Lower power consumption

6. Higher LED life span and uniformity

7. Lower color shift at low brightness

8. Lower pixel and circuit failure
