Digital signage refers to electronic displays that use technologies like Liquid Crystal Display (LCD), Light Emitting Diode (LED), Organic Light Emitting Diode (OLED), projection, and e-paper to showcase digital content such as images, videos, and text. It is widely used in public spaces, retail stores, transportation systems, and corporate buildings to provide information, advertising, and entertainment. Digital signage offers numerous advantages over traditional signage, including centralized control over marketing content, real-time updates, and the ability to use interactive and personalized marketing strategies. This technology enhances customer engagement and provides a more dynamic and efficient way to communicate with consumers.
