Abstract

A method integrates a display, in particular an electronic display, in an outer skin of a vehicle, in one region of a body of the vehicle. The outer skin of the vehicle body, at least in the region of the vehicle body, is formed by a plastic molding, or at least has such a plastic molding. The display is formed together with the plastic moulding, in a joint moulding step, to give a vehicle-body contour, wherein the display surface of the display faces away from the plastic molding.

First claim

The invention claimed is:

1. A method for integrating a display device into a body outer skin of a vehicle in a region of a body of the vehicle, wherein the body outer skin is formed by a molded plastics part at least in said region of the body or at least has such a molded plastics part, the method comprising:
forming the display device together with the molded plastics part in a common molding step to form a body contour, wherein
a display area of the display device faces away from the molded plastics part.

2. The method according to claim 1 , wherein
the display device is connected to the molded plastics part in the common molding step.

3. The method according to claim 2 , further comprising:
providing an adhesion promoter between a rear surface of the display device facing away from the display area of the display device and a surface of the molded plastics part facing the rear surface.

4. The method according to claim 1 , wherein the molded plastics part is formed as an injection molding part, the method further comprising:
placing the display device into a molding element of an injection mold;
closing the injection mold and injecting plastics material for the molded plastics part into the injection mold; and
removing the molded plastics part connected to the display device from the injection mold when opened.

5. The method according to claim 1 , wherein the molded plastics part is formed as a deep-drawn molded part, the method further comprising:
placing the display device into a molding element of a deep-drawing mold;
placing a blank plastics part for the molded plastics part into the molding element of the deep-drawing mold;
deep drawing the display device and the blank plastics part; and
removing the molded plastics part connected to the display device from the deep-drawing mold.

6. The method according to claim 5 , wherein
a rear surface of the display device facing away from the display area of the display device is provided with an adhesion promoter before the blank plastics part is placed into the molding element of the deep-drawing mold.

7. The method according to claim 1 , wherein the molded plastics part is formed as a deep-drawn molded part, the method further comprising:
connecting the display device to a blank plastics part,
placing the blank plastics part and the display device as a unit into a deep-drawing mold,
deep drawing the unit composed of the blank plastics part and the display device to form a molded plastics part connected to the display device, and
removing the molded plastics part connected to the display device from the deep-drawing mold.

8. A vehicle, comprising:
a vehicle body having a body outer skin;
a display unit having at least one display device integrated in the body outer skin by forming the display device together with a molded plastics part in a common molding step to form a body contour, wherein a display area of the display device faces away from the molded plastics part;
a display device controller of the display unit electrically connected to the display device.

9. The vehicle according to claim 8 , wherein
the display device has electrodes and a fluid provided with electrically charged particles, and
the display device operates according to an electrophoresis principle,
wherein an electric field applied to the electrodes of the display device effects an alignment of the electrically charged particles in the fluid.

10. The vehicle according to claim 8 , wherein
the display device is a reflective display device and has electrodes and a fluid provided with electrically charged particles, and
the display device is designed such that, by applying an electric field once, a display is permanently displayed without need for float voltage, wherein the display is deleted or changed by applying an electric field again.

11. The vehicle according to claim 10 , wherein
the display device operates according to an electrophoresis principle, wherein the electric field applied to the electrodes of the display device effects an alignment of the electrically charged particles in the fluid.

12. The vehicle according to claim 8 , wherein
the display device controller has a position data receiver or is connected with such a position data receiver and is configured to be able to ascertain its own current location, and
the display device controller is configured to display on the display device, in the form of text data and/or image data, static or dynamic texts and/or images that are stored in a data memory assigned to the display device controller, in dependence on its own current location.

13. The vehicle according to claim 8 , wherein
the vehicle is equipped with a user identification system, and
the display device controller is configured to display on the display device, in the form of text data and/or image data, static or dynamic texts and/or images that are stored in a data memory assigned to the display device controller, in dependence on user identification data ascertained by the user identification system.
