Light-emitting diodes (LEDs) are found just about everywhere in modern day life. Although they were initially employed as infrared communication devices, today, they can be custom designed for various configurations and applications. LED arrays are assemblies of LED packages built using several different methods. They are typically large, low-resolution forms of dot-matrix displays that are useful for both commercial and industrial information displays. Their brightness allows them to be used in store signs, billboards, and on public transit vehicles. Furthermore, some types of LED arrays can also be used for applications such as disinfection, curing, and surface modification.
