Abstract

A motor vehicle interior trim part for a motor vehicle interior includes at least one integrated organic light-emitting diode OLED, where the motor vehicle interior trim part has a decorative layer, where the decorative layer has a surface structure, and where the visible side of the OLED directly adjacent to the vehicle interior has the same surface structure as the decorative layer.

First claim

The invention claimed is:

1. An apparatus, comprising:
at least one integrated organic light-emitting diode OLED ( 100 ) having an anode and cathode arranged above one another along an axis, and having a visible side, and
a number of organic solar cells ( 600 ) arranged in a plane perpendicular to the axis, wherein the organic solar cells ( 600 ) supply energy to the OLED ( 100 ),
wherein the OLED ( 100 ) is surrounded by the organic solar cells ( 600 ), and
wherein the organic solar cells ( 600 ) are connected electrically in series, forming a chain of solar cells ( 600 ), such that an anode ( 700 ) of a first of the organic solar cells in the chain is electrically connected to an anode of the OLED ( 100 ), and a cathode ( 700 ) of a last of the organic solar cells in the chain is electrically connected to the cathode of the OLED.

2. The apparatus according to claim 1 , wherein:
the OLED ( 100 ) and the organic solar cells ( 600 ) are integrated within a motor vehicle interior trim part ( 103 ) of an instrument panel of a motor vehicle,
the motor vehicle trim part includes a decorative layer ( 200 ) having a surface structure, and wherein the visible side of the OLED ( 100 ) shares the surface structure of the decorative layer ( 200 ), and
the decorative layer ( 200 ) is coloured, and the visible side of the OLED ( 100 ) has the same colour as the decorative layer ( 200 ) in the case that the OLED ( 100 ) is out of operation.

3. The apparatus according to claim 1 , wherein the visible side of the OLED ( 100 ) has a transparent substrate material ( 300 ), wherein the substrate material ( 300 ) comprises a polymer.

4. The apparatus according to claim 1 , wherein the OLED ( 100 ) has a transparent substrate material ( 300 ), wherein a transparent protective layer ( 400 ) is arranged on the visible side of the substrate material ( 300 ), wherein the visible layer of the OLED ( 100 ) is provided by the protective layer ( 400 ), and wherein the protective layer ( 400 ) comprises a polymer.

5. The apparatus according to claim 1 , wherein the OLED ( 100 ) and the organic solar cells ( 600 ) are integrated within a motor vehicle interior trim part ( 103 ) of an instrument panel of a motor vehicle, wherein the OLED ( 100 ) is arranged between a contact region of the instrument panel and a windscreen ( 108 ) of the motor vehicle and forward of a defroster vent ( 102 ) associated with the windscreen ( 108 ).

6. The apparatus according to claim 1 , wherein:
the OLED ( 100 ) and the organic solar cells ( 600 ) are integrated within a motor vehicle interior trim part ( 103 ) of an instrument panel of a motor vehicle, and
the motor vehicle interior trim part ( 103 ) includes a decorative layer ( 200 ) having a surface structure, and wherein the visible side of the OLED ( 100 ) shares the surface structure of the decorative layer ( 200 ).

7. The apparatus according to claim 6 , wherein the visible side of the OLED ( 100 ) is of a same colour as the decorative layer ( 200 ).

8. The apparatus according to claim 1 , wherein anodes ( 700 ) of the solar cells ( 600 ) are arranged in a first plane, and cathodes ( 704 ) of the solar cells ( 600 ) are arranged in a second plane.

9. The apparatus according to claim 6 , wherein the OLED ( 100 ) and/or the solar cells is/are printed or adhesively bonded onto the decorative layer ( 200 ).

10. The apparatus according to claim 6 , wherein a material of the decorative layer corresponds to a material of the visible side of the OLED ( 100 ).
