SMD vs COB vs GOB
LED Display Technology
Choosing between SMD, COB, and GOB LED display technology? Understanding the differences is key to selecting the right LED video wall for your project in Singapore. Our expert comparison covers cost, durability, visual quality, and ideal use cases for each LED technology.
SMD
Surface Mounted Device
The industry standard LED technology. Individual R, G, B diodes are soldered onto a PCB and combined into one package. SMD offers excellent colour mixing, high brightness, and the most flexible range of applications at the most affordable price point.

SMD at a Glance
COB
Chip on Board
Multiple LED chips are mounted directly onto the board without individual packaging, closely packed together for superior uniform light output. COB delivers the best close-up visual quality with virtually no visible pixel gaps, making it the premium choice for high-end environments.

GOB
Glue on Board
GOB technology takes SMD displays and adds a protective layer of transparent, hardened epoxy resin over the LED modules. This creates the most durable LED solution available — resistant to impact, moisture, dust, and static — making it ideal for high-traffic and harsh environments.
