LED is abbreviation of light-emitting diode, it including gallium (Ga),
arsenic (As) phosphorus (P) and nitrogen (N) and other compounds. LED
is a semiconductor device that emits visible light when an electric current
passes through it. Costs less power, more efficient and longer lifespan
than most other light elements. Unlike incandescent lamps, LEDs have no
filaments that can burn out or fail.
LED applies in LED Display/Screen
Indoor LED Displays: SMD Red Green Blue LEDs in one package. Some
outdoor displays do utilize SMD LEDs.
SMD LED Advantages:
No color shift at extreme viewing angles
Smooth color from short distance
Outdoor LED Displays: DIP Individual Red Green Blue LEDs
DIP LED Advantages:
Great for longer viewing distance
