Abstract

The invention relates to a display arrangement (1) for a motor vehicle, for displaying information for an occupant (12) of the motor vehicle. To be able to display the information as cost-effectively as possible in two display areas (4, 5) of the motor vehicle, the invention provides that the display arrangement (1) has an image splitter (9) for separating at least two juxtaposed image sections (B1, B2) of the image.

Claims

1. A device for displaying information for an occupant of a motor vehicle, comprising:

an image splitter configured to separate an image into a first image section and a second image section for projection of the first image section on a first display area and the second image section on a second display area,

wherein the first display area has a spatial separation from the second display area.

2. The display arrangement according to claim 1, wherein the image splitter is disposed in a projection path of the image.

3. The display arrangement according to claim 2, wherein the image splitter protrudes laterally into the projection path.

4. The display arrangement according to claim 1, wherein the image splitter comprises a concave reflector.

5. The display arrangement according to claim 1, further comprising a display screen on which the first display area is arranged.

6. The display arrangement according to claim 1, wherein the second display area is arranged on a field-of-view display.

7. The display arrangement according to claim 6, wherein the field-of-view display is transparent and the second image section is displayed as a virtual image.

8. The display arrangement according to claim 1, further comprising an image duplexer disposed in a projection path of the second image section.

9. The display arrangement according to claim 8, wherein the image duplexer is disposed after the image splitter along the projection path of the second image section.

10. The display arrangement according to claim 8, wherein the image duplexer is configured to project the second image section onto the second display area via two projection paths oriented in different directions.

11. The display arrangement according to claim 8, wherein the image duplexer is configured to project the second image section onto the second display area via two projection paths that are at least partly spaced from each other.

12. The display arrangement according to claim 1, further comprising at least one brightness adjuster, through which a projection path of the first image section or the second image section extends.

13. The display arrangement according to claim 1, wherein the image splitter comprises a concave reflector and wherein the first image section and the second image section are projected onto different focusing planes of the concave reflector.

14. The display arrangement according to claim 5, wherein the display screen is disposed in a dashboard or a center console of the motor vehicle.

15. The display arrangement according to claim 5, wherein the display screen protrudes from a center console of the motor vehicle.

16. The display arrangement according to claim 8, wherein the image duplexer comprises a beam splitter or a semitransparent mirror.

17. The display arrangement according to claim 1, wherein a first projection path of the first image section extends through a first brightness adjuster, the first brightness adjuster being configured to adjust brightness of the first display area, and wherein a second projection path of the second image section extends through a second brightness adjuster, the second brightness adjuster being configured to adjust brightness of the second display area.
