Display device and motor vehicle having a display device

Abstract

A display device for representing information on a display includes at least one display module and at least one cover glass, wherein mechanical insulation is arranged between the display module and the cover glass, and at least one actuator is designed to induce a movement of the display.

Claims

1. A visual display device for reproducing information on a display, the visual display device comprising: at least one display module; at least one cover glass on which the display is shown; a mechanical insulation arranged between the display module and the cover glass; at least one actuator, which is designed to excite a movement of the cover glass, and a touch panel that is arranged between adjacent layers of the mechanical insulation; wherein: the mechanical insulation comprises a flexible bonding that is configured such that the cover glass is mechanically decoupled from the display module, and the flexible bonding comprises an adhesive.

2. The visual display device according to claim 1, wherein the flexible bonding further comprises a viscous medium.

3. The visual display device according to claim 1, wherein the actuator is arranged directly on the cover glass.

4. The visual display device according to claim 1, further comprising: a plastic frame that encloses the cover glass, wherein the actuator is arranged directly on the plastic frame.

5. The visual display device according to claim 1, wherein the actuator comprises one or more of an electric motor, an electromagnetic coil and a piezo element.

6. A motor vehicle comprising a visual display device according to claim 1.

7. The visual display device according to claim 1, wherein the flexible bonding extends entirely over a surface area of the display module that faces the cover glass.

8. The visual display device according to claim 1, wherein the flexible bonding fills an air gap between the display module and the cover glass.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a visual display device according to an embodiment of the invention for reproducing information on a display.

(2) FIG. 2 shows an alternative visual display device.

(3) FIG. 3 shows a further alternative visual display device.

(4) FIG. 4 shows a motor vehicle having a visual display device in accordance with FIG. 1.

DETAILED DESCRIPTION OF THE DRAWINGS

(5) FIG. 1 schematically shows a visual display device 10 for reproducing information on a display 12. The visual display device 10 has a display module 14 and a cover glass 16, wherein the cover glass 16 has a greater surface area than the display module 14. The display module 14 may have, for example, an LCD display. The display module 14 preferably has a touch display such that a user may perform an input by touching the visual display device, which input controls the information reproduced by the visual display device 10. A touch panel may be arranged on one side of the cover glass 16 for this purpose.

(6) A mechanical insulation 18 is arranged between the display module 14 and the cover glass 16, said mechanical insulation serving to mechanically decouple the cover glass 16 and the display module 14 from one another but at the same time to ensure securing between the two components. The mechanical insulation 18 may be formed, for example, as flexible bonding, wherein the flexibility of the bonding ensures the mechanical decoupling. In particular, the mechanical insulation may comprise a viscous medium. The bonding is preferably formed by the viscous medium. In particular, the flexible bonding may comprise an adhesive. In accordance with one exemplary embodiment, the flexible bonding comprises water and an adhesive. In particular, the flexible bonding may comprise a gel or consist of a gel.

(7) An actuator 20 is arranged, for example fixed, on the cover glass 16. The actuator may have an electric motor, an electromagnetic coil and/or a piezo element, which are not illustrated in the figures for the sake of simplicity.

(8) In an alternative embodiment, which is illustrated in FIG. 2, a plastic frame 22 is arranged around the cover glass 16. The plastic frame 22 serves to cover the sharp edges of the cover glass 16 and also to achieve an optically appealing design.

(9) A movement of the cover glass 16 may be excited by way of the actuator 20, for example a lateral movement. This movement may serve as haptic feedback in order to confirm to a user that a performed input was successful.

(10) FIG. 3 shows a further embodiment of a visual display device 10. In contrast to the embodiment shown in FIG. 1, in this case a first mechanical insulation 18 is arranged between the cover glass 16 and a touch panel 23. A further identically formed mechanical insulation is arranged between the touch panel 23 and the display module 14.

(11) FIG. 4 shows a motor vehicle 24 having a visual display device 10, which may be designed as described in FIGS. 1 to 3.

(12) The visual display device 10 is located in the center of the dashboard 26 of the motor vehicle 24. As a result, the visual display device 10 is able to be reached easily by a user sitting on the driver side or on the passenger side.

(13) The visual display device 10 is preferably part of an on-board computer of the motor vehicle 24, which may also have, inter alia, a navigation unit.

(14) The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
