Digital signage uses technologies such as LCD, LED and Projection to display content such as digital images, video, streaming media, and information. They can be found in public spaces, transportation systems, museums, stadiums, retail stores, hotels, restaurants, and corporate buildings etc., to provide wayfinding, exhibitions, marketing and outdoor advertising.
They provide much more flexibility than the traditional paper posters as they allow content to be updated instantly to reflect current needs, they can also be linked to image recognition systems so they can target content at a specific person or group. They can be managed via the internet and produce a cost effective solution across multiple sites.
