Digital signage is the term used to describe the communication of dynamic information to an audience through electronic devices such as display screens, projectors, etc. For indoor purposes, the most common form of display used is the liquid crystal displays (LCDs). Each display can be used as a single stand-alone sign or multiple displays can be connected in a network. The ability to interface with computer networks allows users to communicate information in real-time to an audience targeting their specific wants and needs in an engaging manner.
