How Do COB LEDs Work? A Complete Guide to COB LED Working Principles
COB technology changes the way LED chips are integrated into a display. Instead of treating each LED as a separate packaged component, the technology brings the light emitting chips, electrical connections, circuit board, and protective layer into a closely integrated structure. The way these components interact determines how a COB LED produces light and manages heat during operation. It also explains why the technology is increasingly used in fine pitch LED displays. To understand these advantages, it is useful to follow the process from chip placement and electrical connection to light output, thermal management, and pixel density.
