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 for a vehicle, comprising:

a head down display module;

a head up display module comprising a reflection element configured to at least partially reflect an image from a projection module toward a user and to enable the user to see through the reflection element; and

an adjustment assembly configured to enable adjustment of a first inclination of the head up display module about an adjustment axis and to enable adjustment of a second inclination of the head down display module about the adjustment axis, wherein the adjustment axis is positioned between the head up display module and the head down display module and is substantially perpendicular to a normal viewing direction of the user.

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

3. The display device as claimed in claim 1, wherein the adjustment assembly is configured to incline the head up display module and the head down display module together such that a first change in the first inclination is substantially equal to a second change in the second inclination.

4. The display device as claimed in claim 1, wherein the adjustment assembly is configured to position the head down display module nearer to the user than the head up display module.

5. 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.

6. The display device as claimed in claim 1, wherein the head down display module comprises a first head down display module and a second head down display module.
