Made from compounds containing gallium (Ga), arsenic (AS), phosphorus (p), nitrogen (n), etc. When the electron and the hole compound can radiate the visible light, thus can be used to make the light emitting diode. In the circuit and instrument as a light, or composed of text or digital display. Gallium arsenide diode Red, gallium phosphide diode green light, silicon carbide diode yellow light, gan diode blue light.

Due to the chemical properties of organic light-emitting diode OLED and inorganic light-emitting diode LEDs.
