1. A retractable display device comprising a housing having an internal space defined therein, a rolling axle positioned in the housing, an electronic display comprising a front surface and a rear surface opposite the front surface, and a support structure attached to the rear surface of the electronic display and capable of supporting the electronic display, wherein the support structure extends between upper and lower edges of the electronic display and is positioned within the periphery of the electronic display, and comprises a plurality of juxtaposed support elements being capable of being rolled around the axle with the electronic display in a storage position and of being unrolled upward, at least partially out of the housing, to provide a substantially planar display surface on which visual information may be displayed, and wherein the support structure is hidden from view when the front display surface is at least partially out of the housing;
wherein a first edge of each of the support elements comprises a groove having a triangular section and extending longitudinally, the second opposite edge comprising a tip having a triangular section and extending longitudinally, the tip of a support element being configured to fit into the groove of an adjacent support element when the support structure and electronic display are deployed at least partially out of the housing; and
wherein the angle between the inclined surfaces of the groove and the angle between the inclined surfaces of the tip are each substantially equal to 90°.
