Abstract

A decorative film ( 1 ) for application to a dynamically actuatable display ( 7 ), including:
a carrier ply ( 2 ), a first decorative ply ( 3 ), wherein, in a display area ( 5 ), the first decorative ply ( 3 ) has a first decoration ( 31 ) and one or more transparent areas ( 4 ), in which the decorative film ( 1 ) is permeable to light emitted by the dynamically actuatable display ( 7 ).

A decorative film body ( 10 ) and a display body ( 20 ) with the decorative film ( 1 ) as well as methods for the production thereof.

First claim

The invention claimed is:

1. A decorative film for application to a dynamically actuatable display, comprising:
a carrier ply,
a first decorative ply,
wherein, in a display area, the first decorative ply has a first decoration and one or more transparent areas, in which the decorative film is permeable to light emitted by the dynamically actuatable display, and
wherein the one or more transparent areas are arranged in a grid, and
wherein the one or more transparent areas, in each case have a surface area in a range of from 0.04 mm 2 to 0.5 mm 2 and/or the one or more transparent areas cover a proportion in a range of from 0.5% to 3% of the total surface area of the display area.

2. The decorative film according to claim 1 , wherein the first decorative ply and/or the first decoration is opaque or semi-transparent at least in areas or over the whole surface.

3. The decorative film according to claim 1 , wherein the first decorative ply and/or the first decoration provides a first motif or a first partial area of a first motif, wherein the first motif is a static motif.

4. The decorative film according to claim 1 , wherein the grid of the one or more transparent areas has a grid width in a range of from 1 mm to 5 mm.

5. The decorative film according to claim 4 , wherein the one or more transparent areas are arranged in rows arranged parallel to each other, wherein transparent areas arranged in every second row are arranged offset by half of the grid width relative to transparent areas of the respectively neighboring rows in the direction of the row.

6. The decorative film according to claim 1 , wherein the one or more transparent areas, in each case form a circular surface and/or have a diameter in the range of from 0.25 mm to 0.75 mm.

7. The decorative film according to claim 1 , wherein the decorative film and/or the first decorative ply has a ratio of the transparence in the visible wavelength range in the display area outside the one or more transparent areas to the transparence in the visible wavelength range of the one or more transparent areas in a range of from 5% to 90%.

8. The decorative film according to claim 1 , wherein the decorative film and/or the first decorative ply has a reflectance in the range of from 5% to 90% in the display area and outside the one or more transparent areas and/or has a reflectance in the range of from 20% to 80% inside the one or more transparent areas.

9. The decorative film according to claim 1 , wherein the decorative film, and/or the first decorative ply has a ratio of the reflectance in the display area outside the one or more transparent areas to the reflectance of the one or more transparent areas in a range of from 20% to 80%.

10. The decorative film according to claim 1 , wherein the first decorative ply, has one or more first decorative layers.

11. The decorative film according to claim 10 , wherein at least one first decorative layer of the one or more first decorative layers is a color layer.

12. The decorative film according to claim 11 , wherein at least one second decorative layer of the one or more first decorative layers is an opaque color layer and/or a metallic layer.

13. The decorative film according to claim 1 , wherein the first decorative ply has a protective layer on its outer side facing away from the carrier ply.

14. The decorative film according to claim 1 , wherein the first decorative ply has an adhesive layer on its outer side facing towards the carrier ply.

15. The decorative film according to claim 1 , wherein the decorative film comprises a buffer layer, between the first decorative ply and the carrier ply.

16. The decorative film according to claim 1 , wherein the first decorative ply has at least one metallic layer.

17. The decorative film according to claim 16 , wherein the at least one metallic layer is applied at least in areas in the form of an island layer.

18. A decorative film body for application to a dynamically actuatable display, the decorative film body comprising the decorative film according to claim 1 , and wherein the decorative film body comprises a further decorative ply.

19. The decorative film body according to claim 18 , wherein the further decorative ply is applied to the first decorative ply over the whole surface and/or covers the first decorative ply and/or covers the one or more transparent areas.

20. The decorative film body according to claim 18 , wherein the further decorative ply is semi-transparent at least in areas or over the whole surface and/or has a transparence in the wavelength range visible to the human eye in a range of from 5% to 100%, at least in areas or over the whole surface.

21. The decorative film body according to claim 18 , wherein the further decorative ply has a second decoration, wherein the second decoration provides a static motif or a second partial area of the first motif.

22. The decorative film body according to claim 18 , wherein the further decorative ply comprises one or more decorative layers.

23. A decorative film body for application to a dynamically actuatable display, the decorative film body comprising a decorative film, the decorative film comprising:
a carrier ply; and
a first decorative ply,
wherein, in a display area, the first decorative ply has a first decoration and one or more transparent areas, in which the decorative film is permeable to light emitted by the dynamically actuatable display, and
wherein the decorative film body comprises a further decorative ply, and
wherein a spacer body is arranged between the further decorative ply and the first decorative ply and/or the carrier ply.

24. The decorative film body according to claim 23 , wherein the spacer body comprises or consists of an injection-molding material.

25. A display body comprising a dynamically actuatable display and a decorative film or comprising a dynamically actuatable display and a decorative film body, the decorative film comprising:
a carrier ply; and
a first decorative ply, wherein, in a display area, the first decorative ply has a first decoration and one or more transparent areas, in which the decorative film is permeable to light emitted by the dynamically actuatable display, and
the decorative film body comprising:
a carrier ply;
a first decorative ply, wherein, in a display area, the first decorative ply has a first decoration and one or more transparent areas, in which the decorative film is permeable to light emitted by the dynamically actuatable display; and
a further decorative ply,
wherein the one or more transparent areas are arranged in a grid, and
wherein the one or more transparent areas, in each case have a surface area in a range of from 0.04 mm 2 to 0.5 mm 2 and/or the one or more transparent areas cover a proportion in a range of from 0.5% to 3% of the total surface area of the display area.

26. The display body according to claim 25 , wherein the dynamically actuatable display can be put in a switched-off state and a switched-on state.

27. The display body according to claim 25 , wherein, in the switched-off state of the dynamically actuatable display in the case of an observation of the display body from the side of the decorative film, the display body has a reflectance in the range of from 5% to 90% in the display area and outside the one or more transparent areas and/or has a reflectance in the range of from 20% to 8
