Wolters Kluwer France in Paris, near the Porte de St Ouen has commisioned a digital display from Arch.eu. The company spent two years getting permission for the sign which is on the facade of the building and is 20 metres wide and 4 metres high. The display has a resolution of 1920 x 384 (so around 10mm pitch) and is 9cm thick. Arch said that the installation was completed in a single day, which was essential as the road closure was only for that period.
