Abstract:
1. An electronic device, comprising: (a) a watch case; and (b) an optical device, housed in the watch case, for forming at least one figurative image in a first predefined direction in relation to the watch case, the optical device including wherein each of the at least one optical guide includes at least two networks of optical extractors, wherein each of the optical extractors has predefined geometrical features including at least one reflective or refractive surface, that has a normal oriented so as to face the at least one light source, at a certain predefined angle, such that the light beams emitted by the at least one light source are reflected or refracted, respectively, by one of the first or second networks of optical extractors to form a network of light beams that generates a corresponding figurative image in the direction of an observer, wherein the at least one light source is arranged in proximity to the lateral face of the optical guide, wherein the at least one light source emits light beams in a predefined direction such that is the light beams are reflected on the reflective surface, or, such that it is refracted on the refractive surface, respectively, of one of the networks of optical extractors, and wherein the optical device comprises a sequential operating mode in which the two networks of optical extractors are illuminated sequentially and not simultaneously, thereby generating an animated display.
