Abstract (en)

[origin: US6150949A] PCT No. PCT/EP97/04264 Sec. 371 Date Feb. 8, 1999 Sec. 102(e) Date Feb. 8, 1999 PCT Filed Aug. 5, 1997 PCT Pub. No. WO98/06086 PCT Pub. Date Feb. 12, 1998An optical display device for the representation of signs, especially road signs, in a display frame attached to a support device. The display frame is comprised of strip-shape display segments located at a distance from each other. In order to obtain a small-sized display device perpendicular to the direction in which an observer moves, the support device is aligned in a substantially parallel position to the given direction in which the observer moves, and the display frame is designed to include several display segments, located at a distance from each other, placed behind each other in the direction of movement and corresponding to the chronological order in which the sign is to be represented. The display segments are substantially parallel to the surface normals of the support device for the display frame or inclined at an angle of less than 45 DEG to the surface normals and assigned opposite the sightline of the observer.
