Today we are looking at the benefits of the new COB LED screen technology. Lush were privileged to see a live demonstration at this years 2018 ISE exhibition in the Netherlands with our display partners Absen Optoelectronics & Liantronics
What is COB Technology?
COB (Chip-on-board) LED technology is the latest in full colour product advancement using a state of the art, base of chip surface bonding techniques combined with high precision dispensing.
How is Chip-on-Board technology formed?
The bare Integrated Circuit is mounted directly on the substrate on the back of the PCB, then using a special method of welding using a pure gold wire, a bond is made between the base and the silicon chip, then finally the COB is packaged together to form the full colour module.
What are the advantages of COB Technology?
This new and unique technology has a huge number of advantages over existing technologies such as surface mount (SMD) and DIP LED's. Due to the small size of the LED chip, the COB system allows for a much higher packing density than SMD, the result being a more compact array giving better uniformity and higher brightness intensity even at a close distances combined with greater heat dissipation for better stability, reliability and lifespan.
Lush Digital Media are investing in COB technology in it’s ultra fine pitch LED hire solutions where it becomes the most cost effective
solution for 4K video resolutions.
