To display an image or video on an RGB display board, the image or video data is converted into a format that the display driver can understand. The driver then sends signals to the individual LEDs to turn on or off at specific times, creating the desired color and brightness.
RGB display boards are commonly used in electronic billboards, advertising displays, and other large-scale displays that require high brightness and full color. They are also used in smaller devices such as gaming monitors, televisions, and digital picture frames.
