Sometimes, you might hear from your suppliers that which IC of LED chips do you need? The meaning of built-in and external is simple, but do you know the difference?
1. The external IC strip is controlled by a single IC at the same time. The stability is relatively weak. If there is a LED chip failed, all the LEDs can no longer be used. While the built-in IC strip is one IC that controls one LED chip, adopting one-to-one mode, even if one IC has a problem, it will only affect one LED chip, and other LED chips will not affect the use. That means the built-in IC strip is more stable than the external IC strip.
2. The price is totally different as they will need different production technology.
3. The external IC has solder onto the PCB, which built-in IC has been inside the LED. So their appearance is different.
4. Built-in IC strip can decrease the damaging of the resistors than the external IC strip.
