Ok, I'm wrong lol! We all learn something new.
here's the difference:
A chip on board LED is basically a LED chip diode built directly on the the circuit board. The chips are bonded directly into the PCB at the manufacturer. Without traditional LED packaging ( 5mm LED , 3528 , 5050 , 5630 , 5730 SMD LED ). A Samsung LM301b is closer to a traditional LED like the ones mentioned
