An LED sign is a display that uses light-emitting diodes to convey information or messages. These signs are popular for their bright, vibrant colors and energy efficiency. They can be used for various purposes, including advertising, wayfinding, and public announcements. LED signs come in different sizes and formats, such as digital billboards or smaller displays for shops and restaurants. They can be programmed to show static images, scrolling text, or dynamic animations, making them versatile tools for communication in both indoor and outdoor settings.
