Abstract

The present invention relates to a display device, in particular for a motor vehicle, including a projection module for generating an image to be projected in a direction normal to the viewing direction of a user of the display device along an optical path, wherein the display device includes a reflection element that can be moved between a first rest position and a second display position, the reflection element in the display position thereof being provided in the direction normal to the viewing direction of the user, and the reflection element being subjected to a rotation movement about a fixed rotation axis during the movement of the reflection element between the first rest position and the second display position thereof.

Claims

1. A display device for a motor vehicle, comprising a projection module configured to generate an image to be projected in a normal direction of gaze of a user of the display device along an optical path, and a reflection element which is movable between a first rest position and a second display position, the reflection element in the second display position being arranged in the normal direction of gaze of the user and configured to direct the image along the optical path;

wherein the reflection element is configured to enable the user to look through the reflection element while the reflection element is in the second display position, the reflection element comprises a main extension plane, and, in the movement of the reflection element between the first rest position and the second display position, the reflection element is subjected to a rotational movement about a rotation axis, the rotation axis extending in a direction substantially perpendicular to the main extension plane of the reflection element; and

wherein the display device is associated with a dashboard, the dashboard comprises at least one dial indicator comprising a dial, the rotation axis of the reflection element extends in a direction substantially perpendicular to a main extension plane of the dial of the at least one dial indicator, the main extension plane of the reflection element and the main extension plane of the dial are arranged substantially parallel to one another, and in the first rest position of the reflection element, the reflection element is positioned behind and at least partially concealed by the dial along the normal direction of gaze of the user.

2. The display device as claimed in claim 1, wherein the display device comprises a cover configured to cover the reflection element when the reflection element is positioned in the first rest position.

3. The display device as claimed in claim 1, wherein the reflection element is configured to be driven between the first rest position and the second display position via a motor.

4. The display device as claimed in claim 1, wherein the reflection element is positioned in the first rest position in a slot of the dashboard.

5. The display device as claimed in claim 4, wherein the slot is positioned behind the main extension plane of the dial of the at least one dial indicator along the normal direction of gaze of the user.

6. The display device as claimed in claim 4, wherein the reflection element is subjected to the rotational movement only about the rotation axis from the first rest position in the slot to the second display position.
