DMD (dot matrix display)

A Dot Matrix Display (DMD) is a type of electronic display that uses a grid of tiny dots or pixels to form images or text. Each dot can be turned on or off independently, allowing for the creation of detailed visuals and characters. DMDs are common in digital signs, arcade games, and pinball machines because they are bright, reliable, and capable of displaying dynamic content quickly. Essentially, they work like a digital mosaic, where the arrangement and illumination of dots create a clear, readable image or message.
