The present invention is referred to a portable displaying system characterised in that it comprises: a plurality of connecting nodes in a first and second plane; said connecting nodes have a quadrangular body defining an inner surface, a rear surface and four peripheral edges in which peripheral male connectors with an edge stop are housed; said rear surface has a protrusion with an equilateral cross shape that generates four cavities for receiving the end portions of pivotal joining bars attached to the arms of the equilateral cross; said bars are extended along the vertical or horizontal axis from a first plane so as to be attached by the opposite end portion to the cavities corresponding to the adjacent connecting nodes of the second plane; said bars are crossed and in said cross section being pivotally attached for generating scissor type hinges useful to compact and expand the configured structures; the reinforcement channels with female connection means at 90° or 180° are horiz ontally, vertically or transversally connected, in a tongue and groove manner, to the adjacent corresponding connecting node male connectors for generating squares where flexible, rigid, or semi-rigid panels with different advertisements are fixed.
