Digital signage displays may be LCD or plasma screens, LED boards, projection screens or other emerging display types like interactive surfaces[8] or Organic LED screens (OLEDs). Other, less traditional technologies for digital signage exist, such as 'holographic displays',[9] water screens and fog screens.[10] However, these are typically used for smaller one-off installations rather than large networks.

Rapidly-dropping prices for large plasma and LCD screens have led to a growing increase in the number of digital signage installations.[11] Another price-related benefit that is allowing a larger group of businesses to install digital signage is the increasing availability of newer LCD and plasma display brands in the market. Many locations have opted to forgo more expensive brand name displays for more affordable displays from less well-known companies.
