Abstract

A display device for a motor vehicle includes a display control for generating a first image signal, an image multiplexer for combining the first image signal with a second image signal and for outputting a mixed image signal, and a screen for representing an image depending on the mixed image signal.

Claims

1. to 17. (canceled)

18. A display device for a motor vehicle, comprising:

a display control adapted to generate a first image signal;

an image multiplexer adapted to combine the first image signal with a second image signal and to output a mixed image signal; and

a monitor adapted to display an image as a function of the mixed image signal.

19. The display device according to claim 18, wherein the image multiplexer is adapted to prioritize the first image signal with respect to the second image signal.

20. The display device according to claim 18, further comprising an image-input interface adapted to read in the second image signal.

21. The display device according to claim 20, wherein the image-input interface includes a video interface.

22. The display device according to claim 20, wherein the image-input interface includes at least one of (a) an RGB interface, (b) an LVDS interface and (c) a DVI interface.

23. The display device according to claim 18, further comprising a control-signal interface adapted to read in a control signal.

24. The display device according to claim 23, wherein the display device is adapted to generate the first image signal as a function of the control signal.

25. The display device according to claim 18, further comprising an electromechanical display.

26. The display device according to claim 25, wherein the electromechanical display is controllable by the display device as a function of a control signal.

27. A display device for a motor vehicle, comprising:

a display control adapted to generate a first image signal; and

an image-input interface adapted to read in a second image signal.

28. A motor vehicle, comprising:

a display device including;

a display control adapted to generate a first image signal;

an image multiplexer adapted to combine the first image signal with a second image signal and to output a mixed image signal; and

a monitor adapted to display an image as a function of the mixed image signal.

29. The motor vehicle according to claim 28, wherein the display device includes a control-signal interface adapted to read in a control signal, the control signal including at least one of (a) a speed of the motor vehicle and (b) a rotational speed of an engine of the motor vehicle.

30. The motor vehicle according to claim 28, wherein the display device includes a control-signal interface adapted to read in a control signal, the control signal including at least one of (a) a temperature of an engine coolant, (b) an oil pressure of the motor vehicle, (c) a fill level of a tank of the motor vehicle. (d) at least one of (i) an instantaneous and (ii) an average fuel consumption of the motor vehicle, (e) a driven distance, (f) an average driving speed, (g) an ABS warning signal, (h) a closing status of a door of the motor vehicle, (i) a status of a parking brake, (j) a status of a safety belt, (k) a status of an airbag and (l) a signal of a driver-assistance system.

31. The motor vehicle according to claim 28, further comprising an infotainment system including an image-output interface connected to an image-input interface of the display device by a data link.

32. The motor vehicle according to claim 31, wherein the infotainment system is adapted to generate the second image signal.

33. The motor vehicle according to claim 28, wherein the second image signal includes an image signal for displaying information of at least one of (a) a navigation system, (b) a radio, (c) a DVD player, (d) a CD player, (e) a telephone, (f) a TV module and (g) an air-condition system.

34. The motor vehicle according to claim 28, further comprising a rearview camera connected to at least one of (a) an image-input interface of the display device and (b) an infotainment system of the motor vehicle by a data link, the second image signal including a video signal generatable by the rearview camera.

35. A motor vehicle, comprising:

a display device including;

a display control adapted to generate a first image signal; and

an image-input interface adapted to read in a second image signal.
