Digital signage is a form of electronic display that shows information, advertising and other messages via LCD, LED, plasma displays, or projected images.
Its applications are diverse and can be seen in public and private environments. From retail stores to airports to corporate buildings digital signs can be used for many different purposes. While not limited, some of the most common applications of digital signage are:

Public information – news, weather and local (location specific) information, such as fire exits and traveler information.
Internal information - corporate messages, health & safety news.
Advertising – either related to the location the signage is in or just using the audience reach of the screens for general advertising.
Brand building – building a brand identity.
Influencing customer behavior – directing customers to different areas, increasing the dwell time on the store premises.
Enhancing customer experience – reduction of perceived wait time, customer education and entertainment.
Enhancing the environment – with interactive screens, dynamic way finding; giving the location high-end look.
