We think this LookThruTransparent display by Planar is a great addition to the digital signage range.
The Transparent OLED Display allows dynamic or interactive information to be relayed onto transparent surface glass. This revolutionary display allows users to view what is shown on a glass video screen while still being able to see through it. Designers can overlay text, digital images and video content onto physical objects or scenes that sit behind the glass. How engaging is that!
