A device providing simultaneous visibility of image in the area of 360° around it is conceived in a way to allow visibility of images and simultaneously also allow changing of images during uninterrupted operation and by rendering a not distorted image regardless of the distance of the watching point from the image in the area of 360° around the device. The device of the invention is made of a shield (1), preferably a cylindrical one, which rotates around its axle (2) with an optional drive (3), whereby the shield (1) has a coating with a slot (4) running approximately parallel to the axle (2), whereby the shield (1) has at least one display (5) on the diametral surface or near it, with controlled light points, e.g. liquid crystals (LCD) or light-emitting diodes. The essence of the invention is that there is foreseen a microprocessor controller (9) between a processor (6) and the display (5), said controller adjusting location of each point of image, intended to be seen by the spectator, to a new location on the display (5), depending on the distance of a spectator's eye from the display (5), angle of the display (5) with respect to the line (10) of view and each distance between the slot (4) and the observed point (12) on the display (5). |
