Less than two weeks to the Digital Signage Expo in Las Vegas, and I am thick into putting together my hot list of people and companies to see. I am certain there will be some interesting new hardware on the floor from display manufacturers, both large and small. Super thin OLED, various holographic style displays and refinements in LED panels (making the choice between display panel video walls and seamless LED panel walls that much more interesting) are sure to be present. Of interest to me will be the new, potentially disruptive, technologies that fringe the edges of the show.
