Three-dimensional electroluminescence display

1. A three-dimensional electroluminescent display comprising an electroluminescent device ( 20 ) having a plurality of layers and a transparent or translucent front part ( 2 ), and an electroluminescent apparatus ( 10 ) arranged behind the front part, characterized in that at least the layers of the electroluminescent device ( 20 ) are fixedly interconnected in such a way that these layers withstand a degree of curvature of the electroluminescent device ( 20 ) with a radius of curvature less than 1 mm without cracks arising in the layers of the electroluminescent device ( 20 ).

2. The display as claimed in claim 1 , characterized in that the electroluminescent apparatus ( 10 ) comprises: a front areal electrode ( 11 ) and a back areal electrode ( 12 ), said electrodes being situated at a distance from one another, and a dielectric ( 13 ) situated between said electrodes ( 11 , 12 ), wherein said dielectric is such that it can effect luminescence if a voltage is applied to the electrodes.

3. The display as claimed in claim 1 , characterized in that the front part ( 2 ) is embodied as a film, in that motif ( 9 ) is applied on the back or rear large area of the film ( 2 ) to form a motif layer, and in that the front electrode ( 11 ) of the electroluminescent apparatus ( 10 ) is applied on the motif layer ( 9 ).

4. The display as claimed in claim 2 , characterized in that an outer large area of the back electrode ( 12 ) of the electroluminescent apparatus ( 10 ) is provided with a covering layer ( 14 ).

5. The display as claimed in claim 1 , characterized in that a main body ( 1 ) is assigned to an outer large area of the electroluminescent device ( 20 ).

6. The display as claimed in claim 5 , characterized in that the main body ( 1 ) is provided with at least one depression, in that said depression has at least one side wall which is practically perpendicular to the front area of the main body ( 1 ), and in that the electroluminescent apparatus ( 10 ) assigned to the front wall of the main body ( 1 ) continues with a corresponding portion in the depression, and in that said portion of the electroluminescent apparatus ( 10 ) bears on the side wall of the depression.

7. The display as claimed in claim 1 , characterized in that a converter ( 16 ) is provided, which can convert a DC voltage into an AC voltage, in that the output of said converter is connected to the electroluminescent apparatus ( 10 ), and in that the converter ( 16 ) may be incorporated at least partially in the material of the main body ( 1 ) of the display unit.

8. The display as claimed in claim 1 , wherein one of said layers of said electroluminescent device is an electrode consisting of at least one of: PEDOT, polyaniline and polypyrrole.

9. A method for producing the display as claimed in claim 1 , characterized in that an essentially planar film ( 2 ) is provided, in that one of the large areas of said film is provided with a motif ( 9 ), and in that the electroluminescent apparatus ( 10 ) is assigned to the film ( 2 ) in such a way that the front electrode ( 11 ) of said electroluminescent device ( 20 ) lies on that side of the film ( 2 ) which is provided with the motif ( 9 ).

10. The method as claimed in claim 9 , characterized in that the electroluminescent device ( 20 ) is thermoformed.

11. The method as claimed in claim 10 , characterized in that the thermoformed electroluminescent device ( 20 ) has a plastic injection-molded behind it.
