Patent

CA 2577885

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.

L'invention concerne un appareil d'affichage d'images comportant au moins deux réseaux de sources lumineuses. Chaque réseau peut tourner autour d'un axe commun et les sources lumineuses dans chaque réseau sont agencées, de sorte que chaque source lumineuse suit une trajectoire unique autour de l'axe commun. Un régulateur est adapté pour moduler l'intensité de la lumière émise par chaque source lumineuse à mesure qu'elle suit sa trajectoire unique respective, de sorte que les sources lumineuses, combinées les unes aux autres, rendent une image souhaitée visible par un observateur en vertu du principe de la persistance rétinienne.
