Abstract

The invention relates to a display element for a display unit of a vehicle, said display element being formed from a substrate and a polarizing film. The display element may be backlit by means of a light source. The substrate may be imprinted with graphic symbols. The polarizing film may be a circular polarizing film.

Claims

1. A display element for a display unit of a vehicle, wherein the display element is formed from a substrate and a polarizing film.

2. The display element as claimed in claim 1, wherein the polarizing film is applied to a front side of the substrate.

3. The display element as claimed in claim 1, wherein the polarizing film is applied to the substrate in a non-positive fashion.

4. The display element as claimed in claim 1, characterized in that wherein the polarizing film is glued onto the substrate.

5. The display element (1) as claimed in claim 1, wherein the polarizing film is laminated onto the substrate.

6. The display element as claimed in claim 1, wherein the polarizing film is a circular polarizing film.

7. The display element as claimed in claim 1, wherein the substrate is printed.

8. The display element as claimed in claim 1, wherein the substrate and the polarizing film have substantially identical dimensions.

9. The display element as claimed in claim 1, wherein the display element is backlit by at least one light source.

10. The display element as claimed in claim 1, wherein the display unit is a component of a multifunction display unit of a vehicle.

11. The display element as claimed in claim 1, wherein the polarizing film is applied to the substrate in a positive fashion.

12. The display element as claimed in claim 1, wherein the polarizing film is applied to the substrate in a bonded fashion.
