Most of the way through the first day of DSE and there has been a lot to see. Lots of large format LED panel displays in many configurations, narrow focus speaker systems, and glass with a completely transparent conductive films used to embed arrays of individual LED bulbs in glass with no visible wires.
I am just about to listen to a open presentation on Smart Signage for Smart Green Cities. The same digital ink that has made e-readers can now be used for super low power signage.
More to come later..
