Abstract

A display device, notably for an automobile vehicle, comprises a head down display module, and a head up display module. Means are provided for adjusting the position at least of the head up display module. The inclination of one or both of the head up and the head down display modules may also be adjusted. In such cases, the inclination of the modules may be the same or different. An adjustment axis may be provided for such adjustments, and this axis may be generally perpendicular to a normal viewing direction.

Claims

1. A display device, notably for an automobile vehicle, comprising:

a head down display module, and

a head up display module,

wherein the display device comprises means for adjusting the position at least of the head up display module.

2. The display device as claimed in claim 1, wherein the inclination at least of the head up display module is adjustable with respect to an adjustment axis perpendicular to a normal viewing direction.

3. The display device as claimed in claim 1, wherein the inclination at least of the head up display module is adjustable according to a height of a viewing position of a user of the display device.

4. The display device as claimed in claim 1, wherein the means for adjusting is configured to permit adjustment of inclination of the head up display module and inclination of the head down display module with respect to the adjustment axis.

5. The display device as claimed in claim 1, wherein inclination of the head up display module and of the head down display module may both be changed.

6. The display device as claimed in claim 5, wherein when the inclination of the head up display module and of the head down display module is changed, the change in inclination of the head up display module and the change in inclination of the head down display module are equal.

7. The display device as claimed in claim 1, wherein the head down display module is positioned nearer to a user of the display device than the head up display module, and wherein an adjustment axis is designed to be between the head down display module and the head up display module.

8. The display device as claimed in claim 1, wherein the head down display module comprises at least one display surface with a mobile needle or with a numerical display element.
