Abstract: An object includes an electro-optic display device provided with an optically active element, the optical properties thereof can be modified by applying an electric voltage or current between at least one electrode and one corresponding auxiliary electrode, between which the optically active element is disposed. The object further includes a middle part which delimits an opening closed by a crystal including a bottom surface beneath which the electro-optic display device is arranged. The crystal is provided with an opaque frame which is made remotely from the edges of the opening and which covers the contour of the electro-optic display device so as to conceal electrical connection elements. The electro-optic display device defines an active display area which is confined by the opaque frame, such that, when the electro-optic display device is activated and displaying information, a transparent area remains between the opaque frame and the edges of the opening.

Abstract: An object includes an electro-optic display device provided with an optically active element having optical properties that can be modified by applying an electric voltage. The object further includes a frame which delimits an opening wherein the electro-optic display device is arranged. The object also includes an external electronic power and control device and elements for the electrical connection of the electro-optic display device to the external electronic power and control device, which are hidden by the frame of the object. The electro-optic display device defines an opaque active display area having a surface area that is less than the surface area of the opening, such that, even when the electro-optic display device is activated and displaying information, a transparent area remains between the active display area and the edges of the frame, whereas an area located beneath the active display area is hidden.
