Definitions

  • the present invention relates to an electronic device such as a timepiece comprising a box closed by an ice and inside which is housed an optical device for forming a figurative image visible through said ice.

  • the optical valve is preferably made in the form of a liquid crystal cell carrying transparent electrodes on each of its main faces allowing the polarization of the liquid crystals.
  • the deposition of the electrodes on the faces of the cell uses a method whose costs are not negligible, particularly if the optical system is intended to be implemented on a device for the general public at low cost.
  • such an optical system has a significant complexity in terms of electrical connections as regards the power supply of the liquid crystal control electrodes.
  • the document WO 2004/09773 discloses an electronic device having sequentially activated optical guides and light sources.

  • the light source is disposed at the periphery of the box so as not to be visible through the ice, for obvious aesthetic reasons.
  • the timepiece according to the invention has an attractive display for its wearer because the decorative pattern, or figurative image, thus obtained is light when the light source is powered, while the optical guide is almost invisible when the light source is not powered.
  • the formation of a multicolored figurative image can be provided by the implementation of a plurality of groups or networks of extractors in the optical guide, each group of extractors being associated with its own light source.
