Abstract (en)
The invention provides a self-powered display unit for displaying at least two consecutively changing images to be viewed by a viewer, the unit comprising a housing, at least one wall portion of the housing being made of an array of linear lenses having a lenticular front face and a flat rear face; at least one displaceable, light-weight, substantially planar indicia carrier disposed inside the housing at a distance from the rear face at most equalling the focal length of the lenses, and a high efficiency, low energy consumption, battery-powered DC drive means for periodically displacing the indicia carrier for a distance at least equalling the distance between two adjacent lenses of the array. <IMAGE>
