Abstract:
1. An electronic display apparatus, comprising: an elongated light guide system extending longitudinally to define an elongated display, the light guide system comprising one or more substantially parallel light guides, the light guide system laterally emitting a light feature from a light guide at a longitudinal position along the elongated display, each of the light guides comprising at least one optical fiber having a first end and a second end; a first light source optically coupled to the first end of the optical fiber; a second light source optically coupled to the second end of the optical fiber; and a controller, the controller providing a first input signal to the first light source and a second input signal to the second light source, the controller adjusting at least one of the first and second input signals relative to the other to sequentially select increasing longitudinal positions along the elongated display and cause the first light source to illuminate a first section of the optical fiber and the second light source to simultaneously illuminate a second section of the optical fiber, whereby the light feature is laterally emitted at a transition zone between the first and second sections, the transition zone moving among the longitudinal positions.
