LED display is a flat panel display, which is composed of small LED module panels. It is used to display text, images, videos, video signals and other information. LED, light emitting diode. It is a diode made of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), indium (In) compounds by controlling the display mode of semiconductor light emitting diodes. When electrons and holes are combined, they can emit visible light, so they can be used to make light emitting diodes. It can be used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide phosphor diode emits red light, gallium phosphide diode emits green light, silicon carbide diode emits yellow light, and indium gallium nitrogen diode emits blue light.
