ABSTRACT:
An information display apparatus having a plurality of rotatable elements to create a changeable display of information is described. The display apparatus comprises a frame 1 in which are mounted a plurality of rotatable disc-shaped elements 4, each element having two display surfaces 5 and 6 and an array of activators 12. The frame of elements and the activators are moveable relative to one another. By selectively energising the activators 12, one or more of the elements 4 are rotated to alter the displayed information or image. The display apparatus may be arranged as a cylindrical of linear display. Sensors are positioned adjacent the activators (12) to sense the current position of the rotatable elements to decide if they need to be rotated.
