A light-emitting diode (LED) panel is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors in store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles. LED panels are also used as smart lighting solutions in homes and offices due to their energy efficiency and long lifespan. These panels can be used for various purposes, including advertising, information display, and decorative lighting.
