LED display: A flat panel display consisting of small LED module panels. LED, light-emitting diode (Light emitting diode abbreviation). It is a way to control the display of a semiconductor light-emitting diode, diodes, made of gallium (Ga) and arsenic (AS), phosphorus (p), nitrogen (N), Indium (in), can radiate visible light when the electrons and holes are combined, and thus can be used to make light-emitting diodes. 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, indium gallium nitrogen diode blue light. LED display is generally used to display text, images, videos, video signals and other information.
