Abstract

An omnibearing display, having a display face, with the blanking element in front of the display face, is rotated with a high speed by a rotation actuating mechanism to cyclically and repeatedly appear to eyes of an observer around the display face within a duration of persistence of vision. This results in an effect that observers at any positions around the display face will see the same display face within the duration of persistence of vision, namely, the omnibearing display effect.
