E Ink developer Visionect partnered with German-based RoadAds Interactive developed e-paper based truck displays that provide location targeted advertising in real time. The system also display s GPS-triggered information such as traffic jams ahead, the distance to the next gas station, etc.
RoadAds say that this system bypasses the traditional weaknesses of print advertising - long installation time and stale content. Of course the ads can be more relevant and location based compared to regular print ads. The E Ink displays are efficient and emit no light pollution - which makes them compliant with EU regulations.
