An advertising display board or moving LED display is an electronic board that uses light-emitting diodes (LEDs) to display text, images, and videos. These displays are commonly used for advertising purposes in public places such as shopping malls, airports, and sports stadiums.

The LED display board is made up of a matrix of tiny LEDs that emit light when an electrical current passes through them. The LEDs are arranged in rows and columns to form a grid, and each LED can be individually controlled to create different colors and brightness levels. This allows for the creation of dynamic and eye-catching displays that can attract the attention of passersby.

Moving LED displays are particularly effective for advertising because they can display a variety of content, including text, images, and videos, and can be updated easily and quickly. They are also highly visible, even in bright sunlight, and can be programmed to display different content at different times of the day.
