What is a digital signage?

Digital Signage is a new media concept that refers to a multimedia professional audio-visual system that publishes commercial, financial and entertainment information through large-screen terminal display devices in large shopping malls, supermarkets, hotel halls, restaurants, cinemas and other public places where crowds converge. It aims at a specific physical location, a specific time period for a specific group of people to play the characteristics of advertising information, so that it has the effect of advertising. Abroad, it has also been juxtaposed with paper media, radio, television and the Internet, calling it the "fifth media".
