Light emitting diode LED for short. With Gallium (Ga), arsenic (As), phosphorus (p) and nitrogen (n) compounds, such as steel.

When the electrons and holes can emit visible light when the composite, which can be used to make light-emitting diodes. In the circuit and apparatus as light, or form characters or figures. Gallium arsenide diode glows, gallium phosphide diodes glow green, yellow light silicon carbide diode, diode of gallium nitride blue light. Property can be divided into inorganic and organic light emitting diode OLED light emitting diode LED.
