Abstract: Image display apparatus comprising two or more arrays of light sources is described. Each array is rotatable around a common axis, and the light sources in each array are arranged so that each light source traverses along a unique path around the common axis. A controller is adapted to modulate the intensity of light emitted by each light source as it traverses its respective unique path such that the light sources in combination cause a desired image to be visible to an observer by virtue of persistence of vision.

Abstract: A display module is disclosed, which comprises at least one light source movable along a predetermined path and a controller adapted to modulate the intensity of light emitted by the at least one light source as it moves along the predetermined path so as to cause a desired image to be visible by virtue of persistence of vision. The display module further comprises a drive system for causing the at least one light source to move along the predetermined path and a coupling system adapted to ensure the drive system causes the at least one light source to move, in use, along the predetermined path in synchrony with the light sources on one or more adjacent display modules.
