Abstract: Means to operate the mobile part of an advertisement display stand with image renewal; the aforementioned display stand being the type comprising a fixed transparent part and another transparent parallel, mobile part facing it, one of them fitted with an opacity mask and the other with a number of fragmented images which are interspersed in line with the opacity pattern, so that by adjusting the position of the mobile part in relation to the fixed part, the visualization through the open spaces of the opacity mask of the fragments of one of the images or another in cooperation with the internal lighting may be selected, where the aforementioned means comprise a number of motors that act on different areas of the mobile part, these motors being synchronised by means of a circuit that enables their calibration and levelling.

Abstract: Advertising panel with image updating and improvements of said panel, the panel comprising a casing with internal lamps the light of which is transmitted to the outside through an opening with a rigid and fixed transparent portion and a mobile transparent portion parallel and opposite to the former portion, one of the portions incorporating a pattern formed of opaque areas and the other portion incorporating a plurality of fragmented images that follow the pattern of opaque areas to show selectively through the spaces between the opaque areas the fragments of one of the images using the motion of the mobile portion, the opaque areas concealing the fragments of the other images. The improvements consist of integrating both portions in an opening structure that allows installing the display panel inside another display panel that is part of the street furniture, using the illumination of the latter instead of the illumination of the display panel itself.

Abstract: The system of the invention provides a way to print by digital means of injection of panels with vision on one single side, allowing the incorporation of images and graphics on the opposite side with one single run of the base by means of injection printing.
