<p>An improved mode of construction is provided for a display device of the kind comprising an array of triangular-section slats 12 rotated in synchronism in 120 DEG steps to present repeatedly to view, in sequence, three compound display surfaces, each carrying a respective poster or the like. In embodiments of the invention, each slat has a respective bearing and driving module 14 with a respective rotary member 22 releasably drivingly engaging the slat 12 and with a respective cam 24, driving the member 22 and driven, in turn by a driving shaft 18, passing through the cams 24 of the modules 14 of all of the slats 12. The modules 14 are received in a stack within a hollow extrusion 10a which forms one side member of a frame of the display device. The opposite side member 10b of the frame receives a stack of bearing members 16 rotatably supporting the opposite ends of the respective slats 12. <IMAGE></p> |
