Abstract
A display device for a portable object wherein the portable object includes a dial and at least one movable hand, at least one movable hand includes a light source or is coupled to a light source, the dial includes at least one secondary light waveguide, the light source and the secondary waveguide being arranged such that the light source is coupled to the proximal end of the secondary waveguide when the movable hand moves into a predetermined sector of the dial, and the distal end of the secondary waveguide being coupled to a display element of the dial.
Claims22
A display device for a portable object, comprising:
- a dial and at least one hand movable in rotation over the dial, said at least one movable hand including a light source or being coupled to a light source, the dial including at least one secondary light waveguide having a proximal end arranged in a predetermined sector of the dial and a distal end defining a display area, the light source and the secondary waveguide being arranged such that the light source is coupled to the proximal end of the secondary waveguide when the movable hand moves into the predetermined sector of the dial, and the distal end of the secondary waveguide is coupled to a display element of the dial arranged in the display area,
- wherein:
- said at least one movable hand includes a primary light waveguide, wherein a proximal end of the primary light waveguide is coupled to the light source, a distal end of the primary waveguide and a proximal end of the secondary waveguide are arranged such that the primary waveguide is coupled to the proximal end of the secondary waveguide when the movable hand moves into the predetermined sector of the dial, or
- when said at least one movable hand includes said light source, said light source and a proximal end of the secondary waveguide are arranged such that the primary waveguide is coupled to the proximal end of the secondary waveguide when the movable hand moves into the predetermined sector of the dial.
A watch comprising:
- a display device wherein the portable object includes a dial and two hands movable in rotation over the dial, each of said two movable hands including a light source or being coupled to a light source, the dial including at least one secondary light waveguide having a proximal end arranged in a predetermined sector of the dial and a distal end defining a display area, the light source and the secondary waveguide being arranged such that the light source is coupled to the proximal end of the secondary waveguide when the movable hand moves into the predetermined sector of the dial, and the distal end of the secondary waveguide is coupled to a display element of the dial arranged in the display area,
- wherein:
- the two hands each include a primary waveguide, the primary waveguide of one of the two hands being arranged to be coupled in succession to display elements designating minute indices and the other hand being arranged to be coupled in succession to display elements designating hour indices, or
- when said movable hands include said light source, said light source of one of the two hands is arranged to be coupled in succession to display elements designating minute indices and the light source of the other hand being arranged to be coupled in succession to display elements designating hour indices.
