Abstract
A display device, e.g. for sports stadium or airport, consists of a large array of individual `pixels` representing single dots of a large display. Each `pixel` or display element consists of a number of sets of different colored vanes, some moveable to alter the colors or quality of the light reflected by the element. By using sets of two vanes, each with differently colored areas extending across the vanes transverse to the direction of movement, three distinct color mixes can be provided using two vanes per set, or six distinct mixes using three vanes per set.
