Digital signage

Many signage solutions are not updated very often, even while the relevant information changes rapidly. Digital signage offers a method to display information as it changes in real-time. The digital signs in retail stores, for example, can communicate a change in a price for a special limited-time sale item. Or, they might respond to queries from shoppers. Still, flat panel digital signage is limited to just two dimensions—height and width. With DLP technology, projection displayed digital signs can compel engagement from the viewer, as seen in Figure 3, with moving imagery or non-traditional display surfaces. The front window of a store in a shopping mall might become one massive video display without obscuring the view into the store in the background. Digital 4K UHD projection signage can range from real-time informative to the totally immersive, drawing viewers into the scene on display.
