Digital billboards display images electronically. They are capable of running advertisements from multiple brands dynamically by rotation. They vary in size and location. Large billboards are typically displayed outdoors alongside thoroughfares such as junction points, roadways. Smaller entertainment venues such as sports arenas, malls, etc. carry indoor billboards. Digital outdoor billboards are usually of the same dimensions as static or standard billboards. To create an image, hundreds of LEDs or light-emitting diodes are used by these billboards. Large digital billboards that are sometimes used indoors also use displays that are LED-based. Digital indoor billboards that are smaller in nature use video screens that have LCD or liquid crystal displays. These are similar to televisions or computer monitors. Digital billboards can be installed on a wall or post.
