The COB LED display is one of the most recent LED innovations. While SMD LED can have up to 3 diodes within a single chip, COB LED can have 9 or more diodes. Regardless of how many diodes are soldered on an LED substrate, a single COB LED chip has only two contacts and a circuit. This has greatly reduced the failure rate.
One of the biggest advantages of the COB LED technology is that it can produce more lights or higher brightness with lower power consumption per square inch when compared to the DIP and SMD LED technologies. This is made possible because COB LED chips take up fewer spaces.
Another reason that COB LED chips can be mounted closely together is that it has superior performance in heat dissipation. The aluminium or ceramic substrate of the COB LED chip is a great medium that contributes to higher efficiency in heat conductivity.
In addition, COB LED display has a high level of reliability thanks to its coating technology. The technology can protect the LED screen against moisture, liquid, ultra-violet sunrays, and minor impact.
COB LED display has an obvious disadvantage compared to SMD LED display. It has a lower colour uniformity, and it can result in a poorer viewing experience. Besides, COB LED display is also more expensive than SMD LED display.
COB LED technology is used commonly in fine-pitch LED screens with pixel pitches that are lower than 1.5mm. Its applications also cover both mini LED screens and micro LED screens. COB LEDs are smaller than DIP and SMD LEDs. Higher video resolution can be achieved, and it can deliver an extraordinary viewing experience to the audience.
