Richard Turner, who has worked on tours such as Roger Waters' The Wall, is the screens technical director for One Direction’s On The Road Again Tour. His company, Lucky Frog Ltd, specified a similar video system for the band's last tour, including VER WinAir WinVision 9 screens, which he calls “an established technology in a very lightweight package demanded by the weight restrictions of the stage roof.”
