An LED display is a flat panel display, which uses an array of light-emitting diodes as a video display. An LED panel is a small display, or a component of a larger display. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles or even as part of transparent glass area. LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.
It is a flat-screen device in which an array of light-emitting diodes can be selectively activated to display numerical and alphabetical information, used esp in pocket calculators, digital timepieces, measuring instruments, and in some microcomputers.
