| Digital
signage is a broad term encompassing a variety of different applications
and technologies. In a general sense, digital signage refers to electronically
controlled signs that can be updated without the cost and expense
of changing the physical sign itself. Thus, changes can be made quickly
and cost effectively, and targeted messages can be distributed to
hundreds or thousands of displays at once. Digital signage displays
can take the form of scrolling message boards, plasma monitors, and
large projection screens, as well as other emerging display types
like organic LED. In addition, the creative use of existing display
technologies has led to innovations like polarized projection film,
which allows high-contrast digital signage images to be projected
directly onto store windows. Because digital signs are typically placed
in high-traffic areas, it's important to choose a robust and stable
sign software package to ensure that the right message appears at
the right time. |
