Unlike the tradition of mounting posters and signs on public spaces, the new approach is merely to display contents from computers. The advent of digital signage has expanded advertising past magazine pages and television screens into airports, department stores and other industries. Ditigal signage has four main functions: information release, visual communication, advertising and signs. These functions are fulfilled through the electronic displays of LCD, LED, or projection screens. Leading technology features high-resolution screens, content management software to schedule and update content and an Internet connection for real time data inclusion. The application of this technology is limited only by the user's imagination. A multi-facet in dustry with outlets in retail tentacles and hospitals uses menu boards, information stations, advertising and emergency notification systems. Digital signage is an indispensible tool for engaging your customers, bridging your marketing communications and bringing you new sales opportunities.
