Abstract

A display device for an interior of a motor vehicle has an opaque decorative layer with a display side and a rear side. The opaque decorative layer has at least one opening which extends through the opaque decorative layer from the rear side as far as the display side and which is filled with a light-guiding filling material. At least one illumination source is arranged in the region of the rear side of the opaque decorative layer in such a way that the illumination source emits light through the opening with the light-guiding filling material from the display side of the opaque decorative layer into the interior.

First claim

What is claimed is:

1. A display device for an interior of a motor vehicle, comprising:
an opaque decorative layer having a display side and a rear side, wherein the opaque decorative layer has at least one opening that extends through the opaque decorative layer from the rear side to the display side and is filled with a light-guiding filling material; and
at least one illumination source that is arranged in a region of the rear side of the opaque decorative layer such that the illumination source radiates light through the opening having the light-guiding filling material out of the display side of the opaque decorative layer into the interior,
wherein the light-guiding filling material contains diffusing particles.

2. The display device according to claim 1 , further comprising:
at least one pressure sensor which is arranged in the region of the rear side of the decorative layer and is configured to capture a push actuation by a user on the display side of the opaque decorative layer.

3. The display device according to claim 2 , further comprising:
at least one capacitive sensor system which is configured to capture an approach of a body part of a user at the display side of the opaque decorative layer.

4. The display device according to claim 1 , further comprising:
at least one capacitive sensor system which is configured to capture an approach of a body part of a user at the display side of the opaque decorative layer.

5. The display device according to claim 1 , wherein
the light-guiding filling material is made of a flowable plastic.

6. The display device according to claim 1 , wherein
the light-guiding filling material is made of polyurethane or of an epoxy resin.

7. The display device according to claim 2 , wherein
the pressure sensor comprises at least one piezo element.

8. The display device according to claim 7 , wherein
the piezo element is configured to output, as an actuator, haptic feedback to the user.

9. The display device according to claim 8 , wherein
the piezo element is further configured to trigger, as a switching signal transducer, a function of the motor vehicle.

10. The display device according to claim 7 , wherein
the piezo element is further configured to trigger, as a switching signal transducer, a function of the motor vehicle.

11. The display device according to claim 1 , wherein
the opaque decorative layer has a region with a plurality of openings.

12. The display device according to claim 1 , wherein
the opaque decorative layer is made of wood, plastic, leather, or metal.

13. The display device according to claim 1 , wherein
the opening has at least a diameter of 0.01 to 1.5 mm.

14. The display device according to claim 1 , wherein
the opening has at least a diameter of 0.1 to 0.5 mm.

15. A motor vehicle comprising a display device according to claim 1 .
