What is an LED display?

LED display: a flat panel display composed of small LED module panels. LED, light emitting diode (abbreviation of light emitting diode). It is a kind of diode made of compound of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and indium (In) by controlling the display mode of semiconductor light-emitting diodes. It can radiate visible light when recombined, so it can be used to make light-emitting diodes. Used as indicator lights in circuits and instruments, or composed of text or digital displays. Phosphor gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light. LED display screens are generally used to display various information such as text, images, video, and video signals.
