A visual display is formed by picture elements, which are optically coupled to optical pathways (200) through which light is supplied from light sources (500). Light sources (300), controlled by control hardware (500), transmit light to the optical pathways (200) by scanning light from the light sources (300) to different optical pathways (200). The light sources (300) and the optical pathways (200) are mutually oriented so that light from the light sources (300) can be lead to different optical pathways (200) to form the displayed image. Light sources (300) can be mounted to a rotating mounting (350) that rotates past static pathways (200) that transmit coupled light to the waveguide screen (100).

La présente invention se rapporte à un dispositif d'affichage qui est formé d'éléments d'images couplés par voie optique à des trajets optiques sur lesquels des sources lumineuses fournissent de la lumière. Des sources lumineuses, commandées par un matériel de commande, transmettent de la lumière aux trajets optiques en balayant la lumière émise par les sources lumineuses vers différents trajets optiques. Les sources lumineuses et les trajets optiques sont mutuellement orientés de façon que la lumière émise par les sources lumineuses puisse être balayée vers différents trajets optiques afin que l'image affichée soit formée. Les sources lumineuses peuvent être montées sur un support rotatif qui tourne et passe devant les trajets statiques qui transmettent la lumière couplée à l'écran à guides d'ondes.
