Ever wondered how LED signs work? Electroluminescence is an optical and electrical phenomenon wherein a material emits light in response to an electric current passing through it or to a strong electric field. Essentially, it is a production of light through electrons. This is a process more powerful than the technology behind neon signs, giving led signs an advantage over neon signs. Electroluminescence Example Image Credit: en.wikipedia.org Aside from its energy-saving capacity, led signs are also brighter , more attractive, and capable of displaying multiple animation modes. Led signs use an integrated display system which allows for text, images, cartoons, videos, and other graphic information to be presented. LED signs are composed of led modules, led cabinets, and led displays. Modules are made of LED, PCB, IC, resistors, capacitors, connectors, covers and other components. What’s important to know about them is that their matrices come in sizes of 8×8, 8×16, 16×16, 1
