Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a lateral section view of an exemplary display device according to the invention.

(2) FIGS. 2A and 2B show a top view of an exemplary display device according to the invention.

DETAILED DESCRIPTION OF THE DRAWINGS

(3) FIG. 1 shows a display device 10 comprising an opaque decorative layer 20 having a display side 22 and a rear side 24. The display side 22 faces a vehicle interior. The decorative layer 20 is non-transmissive to light and is preferably made from wood, plastic, or metal, in particular aluminum.

(4) The opaque decorative layer 20 has at least one opening 26 that extends through the opaque decorative layer 20 from the rear side 24 to the display side 22 and is filled with a light-guiding filling material 30. According to the invention, the opening 26 has at least a diameter of 0.01 to 1.5 mm, preferably 0.1 to 0.5 mm. The light-guiding filling material 30 can moreover include diffusing particles. The light-guiding material 30 can be applied to the display side 22 or the rear side 24 for example as a flowable plastic and subsequently be removed (for example by way of grinding) therefrom, so that the light-guiding material 30 remains behind only in the opening 26.

(5) At least one illumination source 40 that irradiates the opening 26 is arranged below the decorative layer 20, i.e. in the region of the rear side 24 of the opaque decorative layer 20. In this way, light is radiated by the illumination source 40 through the opening 26 having the light-guiding filling material 30 out of the display side 22 of the opaque decorative layer 20 into the interior. The illumination source 40 can be arranged, for example, on a base structure 60. A carrying structure 70 can be arranged on the base structure 60, and the opaque decorative layer 20 is in turn arranged on the carrying structure 70.

(6) In FIG. 1, for example a pressure sensor 50 is arranged in the carrying structure 70 below the opaque decorative layer 20, i.e. in the region of the rear side 24 of the opaque decorative layer 20. The pressure sensor 50 is here optional. On account of the pressure sensor 50, the display device 10 can also be used as an operating device. The pressure sensor 50 is designed to capture a push actuation by a user on the display side 22 of the opaque decorative layer 20. The display device 10 can also comprise a capacitive sensor system rather than the pressure sensor 50 or in addition to the pressure sensor 50 in order to capture the approach of a body part of a user (not shown). In this way, the display device 10 can also be used as an operating device. The capacitive sensor system can be embodied, for example, in the form of a sensor film. Since the opening 26 is filled with the light-guiding material 30, the advantages according to the invention mentioned above are obtained.

(7) Moreover, it is possible to arrange the illumination source 40 in a cavity 80. The cavity 80 can preferably also be filled with the light-guiding material 30.

(8) FIG. 1 shows that the illumination sources 40 are arranged in each case below one of the openings 26. It is also conceivable here that one illumination source 40 irradiates a plurality of openings 26 at the same time.

(9) FIG. 2A shows a top view of an opaque decorative layer 20, in which the non-irradiated openings 26 are not visible to the naked eye at typical distances in the vehicle interior. FIG. 2B shows an enlarged section of FIG. 2A. This enlargement depicts symbols, represented by a plurality of openings 26 (such as the vehicle seat). In FIG. 2B, an opening 26 is embodied for example as a circular-round hole or as a micro perforation. Other shapes for the opening(s) 26 are also conceivable, however.

(10) Moreover, the display device 10 according to the invention can also comprise a proximity sensor (not shown) that activates the illumination source 40 when a body part (such as a finger) of a user approaches.
