Abstract

A display with an electro-optical display module has a display area, with a light-transmissive cover arranged between the display area and a possible observer of the display area. The light-transmissive cover is bonded onto the display area by an adhesive, and provision is made for the surface of the light-transmission cover to be configured in a three-dimensional fashion.

Claims

1. A display with an electro-optical display module (1), comprising:

a display area (A);

a transparent cover (3) arranged between the display area (A) and a possible observer of the display area (A); and

an adhesive configured to bond the transparent cover (3) onto the display area (A),

wherein the surface of the transparent cover (3) has a planar inner region (2a) bonded by adhesive onto the display area (A) and a peripheral region (4), the peripheral region surrounding the planar inner region (2a) and having an arcuate cross-sectional profile that extends above the plane of the planar inner region (2a).

2. The display as claimed in claim 1, wherein the transparent cover (3) is bonded onto the display area (A) only in the planar inner region (2a).

3. The display as claimed in claim 2, wherein the transparent cover (3) is bonded at the inner region (2a) in areas of the display area (A) that can be perceived by the possible observer.

4. The display as claimed in claim 1, wherein the transparent cover (3) consists of a film.

5. The display as claimed in claim 4, wherein the film is deep-drawn.

6. The display as claimed in claim 4, wherein the film is printed.

7. The display as claimed in claim 6, wherein the film is printed on a side averted from the possible observer.

8. The display as claimed in claim 1, further comprising spacers (7) distributed in the adhesive (2).

9. The display as claimed in claim 8, wherein the spacers (7) are transparent and have the same refractive index as the adhesive (2).

10. The display as claimed in claim 8, wherein the spacers (7) are uniformly configured.

11. The display as claimed in claim 8, wherein adjacent spacers (7) are uniformly spaced with respect to one another.

12. The display as claimed in claim 8, wherein the spacers (7) each have a diameter of 0.4 mm.

13. A display with an electro-optical display module (1), comprising:

a display area (A);

a transparent cover (3) arranged between the display area (A) and a possible observer of the display area (A);

an adhesive configured to bond the transparent cover (3) onto the display area (A); and

light guides (9) arranged between the display area (A) and the transparent cover (3),

wherein the surface of the transparent cover (3) is configured in a three-dimensional manner.

14. The display as claimed in claim 13, wherein the light guides (9) are configured to decouple light via a light decoupling area (10) in the direction of the transparent cover (3).

15. The display as claimed in claim 14, further comprising a backlit symbol (5a-5i) arranged on the transparent cover (3) above the light decoupling area (10).
